SuperCORR A Dry Lubricant Spray

SuperCORR A

SuperCORR A dry lubricant and protective spray reduces production downtime on industrial automation systemse

Improving manufacturing productivity needs increasing numbers of robots, handling and positioning systems and conveyors which in factory environments need both scheduled and emergency maintenance plans to ensure continuous reliability. Failure of any part of the system will result in downtime and seriously disrupt production.

SuperCORR A  from EnviroTech Surface Technologies is an innovative thin film dry lubricant spray with corrosion protective properties which does not attract dust or dirt, is stable and coats surfaces with an ultra-thin self healing, lubricant film unaffected by water or solvents and resistant to harsh corrosive atmospheres and high temperatures.

A recent case affected some clients of specialist cleaning equipment manufacturer C&C Hydrosonics a division of U.S giant Crest Ultrasonics to solve a problem occurring on x-y axis linear tracks on the Transystem automatic handling system fitted to enclosed multi tank cleaning systems both aqueous and solvent based.

Transystem automatic handling systems are programmable to automatically process baskets or jigs through liquid immersion cleaning cycles, transferring between the tanks, lowering and raising work between the tanks of cleaning liquids. The motorised carriages use nylon wheels running on case hardened mild steel tracks which can corrode during immersion and in the harsh humid atmospheres within the machine canopies.

Corrosion prevents smooth running with wheels seizing and binding on the tracks. Vibration can then cause components to be shaken from jigs or in extreme cases the carriage will stall requiring intervention by maintenance engineers to physically remove surface corrosion and re-lubricate tracks with oil. This is only a temporary measure as the oil is quickly removed by the solvents or water-based cleaning solutions with corrosion reoccurring in a short time.

Extensive trials over a six-month period with both water and solvent based systems demonstrated that SuperCORR A  offered a simple solution to the problem with no corrosion of tracks or seizures during the trial period. Previously seizures needing attention occurred every few weeks now an aerosol spray of SuperCORR A  is used only during normal service visits and is used as the routine lubricant during manufacture of the handling system.

Lee Casey, Managing Director of C&C Hydrosonics is delighted with the cost savings on reduced service and maintenance calls using SuperCORR A and that the inconvenience for users of the Transystem equipment has been eliminated. Use of SuperCORR A is recommended on all Crest handling systems worldwide.

Reduce maintenance costs and protect automation equipment with SuperCORR A .
Now available from EnviroTech Europe Ltd and distributors worldwide.

Eco Friendly Industrial Solvent Cleaners

Clarea Solvent Cleaners

Eco Friendly Industrial Solvent Cleaners, Safe for Users and the Environment.

Cleaning solvents are used in many industries to remove dirt, oil, grease, or other contaminants from machined and fabricated metal, plastic and composite surfaces. Due consideration must be given to the effects on users and the environment.  Some of the benefits of using  Clarea® solvents for these applications are discussed in this article.

Solvents used for cleaning must be highly refined and leave no residues on drying. They have to be very effective in removal of oils and soils without causing damage or corrosion of the parts or components being cleaned and leave minimal residues which will be the result of process design. Cleaning to remove process oils and particles can use single or multitank spray washers or immersion tanks with ultrasonics or agitation depending on the volume of components and cleaning specifications. These vary widely from very demanding automotive and aerospace applications to less demanding applications where critical cleaning is not a requirement.

Pre-used parts or assemblies from the transportation, aerospace or manufacturing equipment sectors are often very heavily contaminated when removed from service but must be free of these oils, soils, grease, dirt and contaminants before handling to disassemble prior to refurbishing and rebuilding. Much of this work will be manual and the considerations for the safety of operators, hand wiping or brush cleaning is paramount. Provision of personal protection equipment (PPE) such as gloves, overalls, safety glasses and possibly masks must be carefully considered to be sure the PPEs are compatible with the solvents.

Among other considerations are the working space where the cleaning applications are to be carried out. Flammability versus drying time is always an issue. It is preferable to use a slower drying high flash point solvent in enclosed areas. Good ventilation with a high extraction rate of air will assist drying. In enclosed machines with automatic handling a positive extraction rate of air and heated and extracted final tank can lower process times. Flame proofing requirements and the insurance implications of the faster drying times of more volatile flammable solvents is often mitigated by the use of less volatile, lower VOC materials by design of machines and careful consideration of costs which these solvents offer in lower usage and longer tank life with much lower disposal costs of used materials.

The growing concerns regarding environmental and health hazards of the most commonly used chlorinated solvents for industrial degreasing and cleaning has led to the formulation by EnviroTech Surface Technologies  of the Clarea®  range of safer cleaning solvents.

Clarea® solvents can be used for spray or immersion cleaning for very heavy soiling or in multitank processes to meet the highest standards demanded for critical cleaning. They can be used as wipe or brush cleaners for large surface areas prior to painting or powder coating.

Why should you choose Clarea® industrial cleaning solvents.

The solvents applied during production or finishing processes have a direct effect on the health of workers and the environment. Volatile organic compounds or VOCs are chemicals which vaporise at room temperatures. Traditional solvents used for cleaning have low boiling points and a high VOCs making them harmful to use and less eco-friendly Exposure to the VOC’s released by these cleaning agents must be controlled to prevent respiratory, allergic, and immune system complications for users. If your company uses industrial degreasing agents regularly, it is time to evaluate the implications of this choice.

Clarea® is a less volatile alternative than conventional cleaners. Highly refined aliphatic hydrocarbons with minimal residues and tight vaporisation ranges are capable of providing the same results and can be substituted to create a safer, sustainable, eco-friendly workplace. The low odour, low flammability and low toxicity of Clarea® solvents provides performance and operator and environmental acceptability using less material at lower costs. Multipurpose use can reduce the inventory of cleaning fluids stocked.

Clarea® HC40 for brush and hand wiping, air dries. Flash point 40℃.

Clarea® HC62  for dip cleaning with agitation or ultrasonics. Low evaporation. Non-flammable.

Condensation Cleaning

The future for solvent vapour degreasing equipment – Innovation driven by legislation.

Vapour degreasing is the simplest but most effective degreasing and cleaning process for industrial use.  It has, until recently, been subject to little change since it was first invented in the early part of the last century. The name for the process is a misnomer as the cleaning is achieved  by solvent vapour condensing on the cooler target parts the hot liquid solvent dissolving oil and removing dirt.

Vapour degreasing is a mature chemical technology on which legislation is now effecting changes so fundamental that the more accurate name for the process “Condensation Cleaning” should be used to reflect the way in which it works. The open topped tanks so ubiquitous in factories and workshops worldwide are no longer acceptable and the alternatives in equipment design and their  fundamental differences in  technology  which guarantee the continuing use of vapour degreasing in the future need to be considered and understood.

In Europe the United States and in other advanced industrialised economies increasingly stringent legislation to control emissions of VOCs and especially solvents has led to new formulations for paints and other coatings where water replaces most of the solvent. In the early days the quality of the coatings was not as good as solvent based coatings but innovation has driven the development of new polymers with results as good as, if not better than, the solvent based originals.

As with coatings, cleaning systems have had to change. With increased regulation users of solvent have been targeted and alternatives are encouraged by the relevant authorities and law makers often without serious consideration of unintended consequences.

For example water based cleaning is the obvious alternative but this has many disadvantages compared to condensation cleaning as although the machines are simple and relatively cheap the processes require multiple tanks for immersion or spray processing or long programmed cycles in batch machines for cleaning, rinsing and drying. Water based processes are slow, energy intensive and occupy more floor space than  condensation cleaning equivalent where only one tank with small footprint is needed delivering shorter process times and most importantly using minimal energy.

The ideal cleaning process would be “Condensation Cleaning” with water but due to the physical characteristics of the water vapour/steam and the inability to carry onto the surface of the targeted parts surfactants to remove the oil, grease and soils and the difficulty of rinsing and especially drying this can only ever be a dream.

A little history of the chemistry helps to explain the changes since the introduction of the vapour degreasing process. Suitable chemicals must be very good solvents for oil, grease, and other industrial soils non-flammable, safe for users and the environment and very stable when heated continuously for long periods.

Halogenated hydrocarbons are the solvents of choice for “Condensation Cleaning”. The process is essentially simple. A tank with a sump to contain the solvent, heaters at the base and condensation coils around the top section to control the height of the vapour is all that is required.  When heated in the sump halogenated solvents produce, a saturated vapour between 3 and 4 times heavier than air at a temperature greater than the ambient conditions. This allows the solvent vapour to condense on the surface of the parts to be cleaned. The condensate dissolves the contaminants such as oil, greases and soils returning the used solvent into the sump of the machine for recycling into vapour which continuously condenses onto the parts until they have achieved the same temperature as the solvent vapour when, with no further condensation, the process is complete. Parts removed from the cleaning machines are very clean, warm and dry.

The most common halogenated solvents, in use for commercial purposes, are non-flammable so present no risk in this process. Perchloroethylene, used mainly for dry cleaning, methylene chloride used more widely in paint strippers and trichloroethylene used for vapour degreasing were the original materials used based on chlorine chemistry. However continuing concern about the environmental impact and danger to operators by exposure to chlorine based solvents, especially trichloroethylene, has led to a continuing search for safer alternatives.

1,1,1 trichloroethane (Genklene from ICI and Chlorothene from Dow Chemicals)  both of which were based on another chlorinated solvent  were to become ubiquitous in the mid part of the last century as a much safer, non- carcinogenic replacement for trichloroethylene. This was an excellent solvent safe for users but which, with increased awareness of the environmental impact of solvents, proved to be depleting the protective ozone layer around the Earth and was subsequently, banned. With the development of the REACH legislation in Europe, which now classifies trichloroethylene as a human carcinogen, usage is allowed but with restrictions and stringent controls for use  authorised in machines which control factory emissions to very low figures close to zero.

Meanwhile cleaning solvents based on 1-bromopropane such as EnSolv were developed in the United States as a drop in replacement for trtichloroethane. EnSolv has an identical profile, stable, non-flammable, with the same physical characteristics such as boiling point and specific gravity and it is an excellent cleaning solvent but without the potential for ozone depletion.

During this time new halogenated solvent blends using trans1.2 dichloroethylene, a highly flammable solvent with similar chemistry to trichloroethylene were also developed for condensation cleaning.  The trans 1.2 dichloroethylene is blended with a variety of different fluorocarbon solvents which are not suitable as cleaning solvents, as they have very low solvency, but are used in these blends as a fire retardants.  An extremely expensive answer to a simple problem, already solved by the development of machines able to safely use the more economical solvents.

As with all legislation for the use of chemicals regulation and restrictions drive development of associated processes and equipment. The most important developments in machines to use solvents for condensation cleaning use two different approaches and  raise difficult questions as to which is the best most economical and simplest in use.

Solvac Automatic hermetically sealed vapour/liquid cleaning system

Figure 1 – Solvac Automatic hermetically sealed vapour/liquid cleaning system conveyor fed.

The single tank hermetically sealed machines favoured by some equipment manufacturers uses a process tank to contain the solvent and a separate storage tank/vapour generator. Baskets, containing soiled parts, are loaded from the top or through access points on the side of the tank. Lids or doors close over the opening and the process tank is hermetically sealed.  Baskets are immersed in solvent, where agitation, ultrasonics or pumped liquid is circulated through the parts.

When the immersion process is completde solvent is removed to the storage tank and vapour fed to the process tank from a vapour generator for rinsing and drying. On completion of the cycle coil,s located within the process tank  collapse the vapour.  The process tank is evacuated by vacuum and recycled through carbon absorption units to remove traces of solvent from the air until the concentration is below limits set by regulators when the lid opens automatically for the basket of parts, clean and dry, to be safely removed and replaced with a further basket.

Variations of process within the hermetically sealed tank are possible using sprays of cold or hot condensed solvent, immersion with or without ultrasonics and revolving baskets to deal with the problems experienced when processing machined and fabricated parts. Continuous external distillation of the contents of the vapour generator is also an option depending on contamination.

The alternative technology is much simpler and cheaper using well tried techniques not requiring the long recovery times of the hermetically sealed processes. The multilevel system uses a standard vapour degreasing tank design with a sealed loading section above the process tank.

Solvac 1000

Figure 2 Solvac 1000 – Hermetically sealed multilevel vapour degreasing system for manual load batch processing.

Components, to be cleaned, in baskets or on jigs, are fed to the automated hoist in the load section manually, by hoist or conveyor. The loading door is  sealed pneumatically to completely isolate the process. The process tank sealing lid opens and the basket lowered into the process chamber. Depending on the soils  simple condensation cleaning can be used or with the lower section being filled with clean solvent for immersion cleaning with or without ultrasonics or power sprays. Revolving baskets are a further option to improve cleaning in blind or through holes or oil ways in castings and fabrications.

With the process completed the basket rises to the freeboard area where the condensation coils are located and parts allowed to drain and dry.  The tank seal opens to allow the basket into the load section while the lid closes to seal the  process tank. A fan is then activated which produces a negative vacuum in the load area. The loading door partially opens to allow a flow of air through the loading section which is exhausted to atmosphere or can be recycled through carbon absorption systems.

As baskets entering the loading space contain parts drained and dried only very small amounts of solvent are carried in the exhausted air which is monitored to ensure compliance with appropriate legislation. When this is completed the door opens fully for removal of cleaned components. The loading section can be fitted with top or side sealed doors allowing baskets to flow through on conveyor systems or be loaded from hoists. No solvent enters the work area.

Both processes will produce parts cleaned to the highest standards but the choice of which offers the best solution needs a little more consideration.

The hermetically sealed vacuum process is complicated with the need to move liquids in the machine. It is relatively slow as the carbon adsorption process needs to remove high levels of solvent from the recirculated airstream from the process tank. This is inefficient as adsorption rates for carbon fall rapidly with increasing saturation.  Final levels of solvent in the tank when the lid or loading door opens will be emmited into the workspace and the area in which the operator is working. Long process cycles reduce throughput.

The simpler multilevel systems where movement of liquids is not required are more efficient and offer much faster process times.  Cost of manufacture is also lower as no liquid movement or vacuum is involved. The extracted loading section ensures no leakage of solvent into the work area which gives complete safety for operators and factory staff.  The disadvantage of the multilevel machine is the height of the equipment compared to the hermetically sealed machine.  This will often need the equipment be installed in a pit for easy access.

Both designs of process machines fully comply with the emission regulations of the EU and U.S authorities. Which to choose will depend on many factors which should be discussed with both the equipment and solvent suppliers who have the experience to advise on which offers the best process for the application. Equipment and solvent work together as a process and it is essential to ensure that the suppliers work closely together to offer a package with high levels of responsible care and product stewardship to ensure the best results and safest installation.

The “Condensation cleaning” process still gives the highest levels of economical cleaning with minimum energy usage, low footprint on the factory floor, safety for the operator, and high production rates with low solvent usage or environmental impact. With the new generation of sealed cleaning machines its future as the process of choice for industrial cleaning is assured.

Reduce Corrosion Fretting

Why use of SuperCORR A for maintenance of electrical connections on Gas Turbines improves performance by reducing corrosion fretting.

SuperCORR A for maintenance of electrical connectionsLP Gas Turbines are used throughout the world by extraction industries and manufacturing plants in remote and hostile locations for essential power production. Dusty and wet environments in deserts, mines, grinding mills, pulp and paper mills and on land or sea drilling rigs for gas and oil production. Turbines powering aircraft services while stationary connect and disconnect many times a day in extreme conditions. These applications and locations test connector sealing continuously allowing dust or water to penetrate. This with the flexing of the connecting cables allows sufficient movement between the metal surfaces of the connecting pins to produce fretting corrosion which reduces, interrupts or produces failures in supply.

Regular maintenance of electrical connectors is essential to be certain of uninterrupted supply.

SuperCORR A is an aerosol lubricant containing corrosion preventive compounds, and, as is the case with all lubricants, they can be worn off over time. A manufacturer of connectors tested SuperCORR A to see what the “life” of the lubricant was in a “rub test”. The typical test is 20,000 cycles, i.e. unplug, plug in is one cycle. The test results demonstrated that after 20,000 cycles there were no failures. It was decided to take it one more step and run the same tests for 200,000 cycles. The results again showed no indications of galling or scoring on the connectors at all. The connector looked and tested as good as new. This test
was run under clean conditions in a laboratory but demonstrates the effectiveness of the protective lubricant in SuperCORR A.

As it meets Mil-DLT-87177B specifications it is used by the U.S. Air Force to protect the intricate workings of the F-16 and F-15 fighter jets and by the U.S. Navy on the P 3 Orion electronic surveillance aircraft. Savings for the U.S. government is estimated at $50 million per year. Commercial Aviation aircraft manufacturers recommend it for avionics and electrical switches and connectors and close mechanical application, especially where flights are in salt fog or high humidity.

Containing extremely long-lasting, proprietary anti-corrosive inhibitors SuperCORR A provides a superior lubrication coefficient and protects components against moisture, wear, general and fretting corrosion, surface static electricity, corona, and other electro migration problems. The super thin non-flammable lubricant film is only 7 microns (0.0007 inch) thick and is formulated without sulphates, chlorides or halogens to meet the RoHS directive. It is unexcelled in preventing deterioration and contamination on all surfaces of electronic equipment.

Very fast drying environmentally acceptable solvents are used as carriers and propellants which will not affect most plastics, substrates, metals or other materials used in connector manufacture. The aerosols are supplied with probes which allow access to pins and connector tubes where the low surface tension repels water, dirt dust and metal particles from blind holes and surfaces to produce thoroughly clean holes and surfaces before a second application applies the lubricant film. Reconnection to the supply with cleaned sections of the connector ensures reliable operation even in the most testing of environments. This easy maintenance from one can of SuperCORR A allows this essential task to be carried out in any conditions quickly, easily and securely.

Managing “false alarms” and “no fault found” events in Military avionic systems.

Paper presented at the recent 2017 Aviation Electronics Europe Expo in Munich by Dr. Mustafa Ilarslan, PhD.

In a paper presented at the recent 2017 Aviation Electronics Europe Expo in Munich, Germany, Dr. Mustafa Ilarslan, PhD, discussed –  “The management of “False Alarms” and “No Fault Found” events in Military avionic systems”.

In his paper Dr. Ilarslan explains that “False alarms (FAs) impose a devastating impact on military systems.  An entire aircraft can be grounded because of a single avionics for which there are insufficient spares available. If a FA causes a particular Line Replaceable Unit (LRU) to be called out incorrectly, there is a better than even probability that a second copy of the same LRU will also experience FA and much sooner than expected, the fleet will be deprived of all spares for that LRU.  To then find that the LRUs replaced had No Fault Found (NFF) at the repair depot adds “salt to the wound.” while adding huge sums  for lost time in servicing, aircraft downtime  and unnecessarily high stocks of replacement parts.

SuperCORR-A was designed specifically to prevent  these problems in avionic as well as electrical and electronic components and systems failures caused by corrosion, including no fault found failures and problems caused by Cadmium corrosion. SuperCORR-A is a proprietary Ultra-Thin Film, Water Displacing Lubricant and Corrosion Preventative Compound, manufactured under license in the UK by EnviroTech Europe Ltd.

SuperCORR-A  is being used on both military and civilian aircraft to prevent fretting corrosion on electronic and electrical connectors, including F-16, P-3 Orion, Boeing 737’s, C-130, F-15,  DHC-6 Twin Otter, Bell helicopters, Bombardier BD-700 series and Bombardier Challenger 300/350, Learjet 45, Legacy 650, and Hawker to name but a few.

SuperCORR-A  is also being used at BAE Systems, Honeywell and Raytheon Systems to prevent corrosion from causing avionic, electronics, and electrical systems and components failures and for lubrication and protection of moving parts with a thin dry film.

SuperCORR-A meets the requirements of  MIL-L-87177A and Mil-DTL-87177B.

Preventing hydrogen sulphide corrosion in electrical and electronic equipment

CORR-EX LCP-177

A Cost Effective and Proven Corrosion Preventative Solution.

By Larry Clark, EnviroTech Europe Ltd

Electrical and electronic equipment and components that are used in adverse work environments, e.g. the oil and gas industry, waste water treatment plants, and the pulp and paper industry, where corrosive gases such as hydrogen sulphide are found cause severe corrosion and the rapid deterioration of the electronic components and equipment including connectors and switches used in these and other work environments. One economical way to prevent or inhibit corrosion from destroying electronics and electrical components is to use CORR-EX LCP-177, Ultra Thin Film, Water Displacing, Lubricant and Corrosion Inhibiting Compound.

If you or your company aren’t worried about costs then by default you aren’t concerned about corrosion or it’s associated costs in lost productivity and lost revenue caused by plant and equipment down time then this a paper that you should just skip. But if you and your company are concerned about costs including the amount money and man hours to repair or replace components to keep an electrical system or electronics operating, an aircraft flying, or a machine running because of failures caused by corrosion then this paper is for you!

Corrosion, in its many forms, is costing both private and public sector hundreds of billions of Euros a year! While all metals corrode due to a number of different factors there is no simple or single solution to the overall corrosion problem. However there are some very cost effective and proven ways to prevent corrosion and failures caused by corrosion and thereby reducing or eliminating associated costs and increasing safety which should be foremost in the mind set of any Preventative Maintenance Programme manager.

One proven and cost effective solution to the corrosion problem is CORR-EX LCP-177, a water displacing, ultra thin film lubricant with corrosion preventative properties. CORR-EX LCP-177 was designed specifically to lubricate and prevent corrosion in electrical fittings and connectors; electrical and avionic harness assemblies and connectors; electrical and electronic switches; close tolerance and dissimilar metal components; lighting connectors and sockets; and the list goes on and on.

CORR-EX LCP-177 is a unique non-flammable “self healing” ultra thin film lubricant with a proprietary corrosion preventive compound that will not harden or crack. CORR-EX LCP-177 is not a wax or oil based product and is formulated without sulphates, chlorides or halogens.

CORR-EX LCP-177 inhibits corrosion caused by exposure to both fresh and salt water moisture as well as the corrosive vapours from Sulphur dioxide (SO2), Nitrogen dioxide (NO2), Hydrogen Sulphide (H2S), Ammonia (NH3), and Chlorine (CL12) based gases found in waste water and sewer treatment plants, pulp and paper mills and plants, chemical and petroleum plants, maritime industry, aircraft/airline industry, military equipment including ships, aircraft, and rolling stock, auto industry, farming and agriculture industry, and the list goes on. Extending the working life of electrical components and systems and other critical items by preventing the deterioration and/or failure caused by corrosion can significantly reduce downtime and operating and maintenance costs as well as enhance safety.

The question for you is: What is the cost of NOT using CORR-EX LCP-177 in your Preventative Maintenance Programme?

CORR-EX LCP-177 is available from EnviroTech Europe Ltd and distributors worldwide.

More information about CORR-EX LCP-177 is available here.
