Problems caused by conventional cleaning and metal pretreatment systems

metal treatment

Exploring a new solution to the problems caused by conventional cleaning and metal pretreatment systems in product finishing.

EnviroTech Surface Technologies looks at some of the traditional problems associated with solvent and aqueous degreasing prior to painting and powder coating and explains how the DriPHOS® option can offer a viable alternative to conventional processes. The DriPHOS® surface treatment process has evolved to produce a revolution in metal finishing.

DriPHOS

DriPHOS® the start of a great finish

Traditionally jobbing painters and/or manufacturers of parts who have to subsequently degrease and then paint or powder coat have had the same problems that they have learnt to live with. These include: reject rates of between 3 – 8% after painting; residues of particulate that require further manual wiping after degreasing and prior to painting; paint schemes lifting or blistering; corrosion forming under painted areas; parts slowing down the production because the drying oven takes an excessively long time to dry sufficiently; or parts simply going rusty during the dwell time between cleaning and subsequent painting.

Finally, when using conventional solvents, long dwell times whilst the components cool down to a temperature that can take the paint prior to curing in the oven. More recently, classification of Trichloroethylene has also caused concern. These and others must sound familiar to you.

 

What causes this to happen?
Obviously a lot of factors come to mind but generally they fall into four main areas as follows:

● Inadequate degreasing
● Residual contamination
● Retained moisture or solvent under the surface of crimped areas, spot welds and seams etc
● No protection from rusting whilst awaiting painting

Why does this happen?
To try to simplify this we have broken it down into aqueous cleaning and solvent cleaning with some of the reasons under each of the four headings above as follows:

MAIN CAUSES AQUEOUS METHOD SOLVENT METHOD
INADEQUATE DEGREASING – Solution out of spec or contaminated
– Temperature to low
– Rinses contaminated
– Filters blocked
– Only vapour used
– Poor loading
– Wrong solvent used
– Solvent turned acidic
RESIDUAL CONTAMINATION – Wrong product used
– Contaminated rinse water
– Poor loading
– Particulate left by vapour
– Solvent turned acidic
– Poor loading
RETAINED MOISTURE – Insufficient time to dry
– Poor loading
– Parts not designed to drain properly
– Solvent trapped in parts
– Parts not designed to drain properly
NO INTERIM PROTECTION – No corrosion inhibitor
– Residual contamination
– Solution out of specification
– High temperature draws moisture from atmosphere

All of the above are avoidable but may mean tighter controls and different process methods are required. The way the components are loaded is vitally important as overlapping can prevent access for both the aqueous and solvent processes. Unfortunately most paint shop managers will not feel they can afford the time to load more carefully even when they realise the advantages.

What can be used as an alternative?
The answer is DriPHOS®  the new  single tank surface treatment process.

What is DriPHOS®?
It is a solvent-based degreasing and pretreatment process. Based on a well-tried and tested blend of solvents and sophisticated additives and surface activators, DriPHOS® really is the quickest, most economical answer to degreasing and surface treatment  problems. Operating at only 42°C the parts come out of the process totally clean, dry and with a crystalline primed surface to enhance painting and cool enough to handle or to go straight into the paint area. One tank is all that is needed.

How does it work?
It works by a combination of vapour and immersion stages in one tank.  After initial degreasing in the vapour, parts are then immersed into the DriPHOS® boiling sump where the residual oils and particulate is removed and the phosphate coating is chemically bonded to the surface of all of the parts. After a mini rinse/ final vapour stage the parts are left in the freeboard area for a short time before coming out of the tank totally clean, dry and with a protective surface coating. This gives an excellent bond for subsequent painting operations, with minimal reject rates due to delamination or undercoat staining. . The crystalline coating gives inter-stage protection until painting is needed. Another bonus is the colour change of the metal surface  gives a visual indication of quality. The process can be used on steel or aluminium components or mixed metal components or fabrications. For steel parts a total process time can be as little as 3 – 5 minutes. Aluminium parts will be 1 –2 minutes. Bath life averages 2 years. One tank needs little space and uses only small amounts of energy. A very fast, economical and simple to run process.

Why doesn’t everyone use it?
The truth is that, like all processes, it will not work for every application but a quick visit by one of our DriPHOS specialists will confirm if it would be a practical solution to improve the finish on your products. We back this up with full technical support, solvent monitoring, equipment advice, operator training, and a lot more.

Degreasing and rust prevention is essential for stored metal parts

metal treatment

How degreasing and rust prevention is essential for stored metal parts in flexible manufacturing processes.

Flexible batch production for variable numbers and colours of finished products is very difficult to achieve when producing fabricated items in mild steel sheet due to storage of the unpainted parts being subject to rusting and corrosion when processed by conventional water based processes. This paper describes a typical manufacturing cycle for office and educational equipment where rust free storage allows JIT deliveries.

DriPHOS

To satisfy contracts to produce a wide range of metal cabinets, chests, and lockers in many different sizes with a range of cabinets and shelving, all in different colours, for the education sector which have to be delivered within 7 days, needs very careful production planning. It is necessary to stock drawers, tops and backs, punched, laid flat, unpainted, and then produce sides to order. Three pieces of equipment allow successful operation of this production process. A CNC controlled sheet metal folding and bending centre an automatic DriPHOS combined degreasing and metal pre-treatment process tank and a fast colour change powder or paint coating plant and an oven.

In the case of the bending operation, a stock of pre-punched blanks is carried which when a ‘rush’ order is received the automated CNC folding system, will typically produce the end folds in a pair of sides, within ten minutes – without disrupting normal planned production.

The DriPHOS pre-treatment operation is critical to achieving these very tight schedules. A fully integrated CAD/CAM system enables a product to be taken from concept to finished item. Manufacture of batches of storage cabinets from tens to 500 off will need up to 20,000 items of sheet metal work and shelving. Batches of machined parts which must be stored, for long periods, can be transferred to the pre-treatment cell and loaded into a basket or jig, positioned to allow good circulation of DriPHOS solution around the parts.

The loaded basket is placed onto an automated handling system to raise and lower work within the enclosed process tank to a defined cycle. The DriPHOS process is similar to vapour degreasing and requires minimal space as only one tank is involved rather than the altern ative multi tank water based systems. Held in the vapour zone above the boiling DriPHOS solution, vapour condenses on the components until the temperature equalises at 31°C. This degreases the surfaces and removes loose dirt as it is flushed away by the condensed DriPHOS. After immersion in the solution for 2- 3 minutes, the basket/ jig is raised into the vapour zone where it is spray-rinsed for 30 seconds with cooled DriPHOS distillate to remove traces of process liquid. Residual condensate flash evaporates as the basket is slowly removed from the tank. The whole cycle takes only five minutes.

DriPHOS enables finished parts to be degreased, pre-treated and protected prior to assembly. Any other process would have to see parts painted in no more than an hour after treatment during which time rusting may occur. DriPHOS on the other hand presents a physical barrier against moisture, inhibiting rust and corrosion. Parts can be assembled and painted up to a year after treatment.
Whether direct from the degreasing and pre-treatment cell or from pre-treated stock from storage, cabinet ‘carcases’ are assembled, TIG welded and ‘jigged up’, along with shelving, doors etc on a motorised overhead carousel. They progress into an automated paint or powder booth with two open stations, for manual spray operations, for operators to ensure all internal corners are covered. The complex crystal structure applied by the DriPHOS process uses thin layer technology (TLT) to produce a crystalline bond that is integral with the metal substrate, increasing the surface area and providing an excellent key for paint, powder and other finishes.

Painted units are passed through ovens from where final assembly sees shelves, doors, handles etc fitted. Finished units can be packaged and despatched the same day. Providing metal storage systems from stock would not be possible without DriPHOS as a pre-treatment solution for rust and corrosion free storage of the sheet metal parts.

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.

Trichloroethylene a known human carcinogen

Trichloroethylene formally listed as a “Known Human Carcinogen”.

Replace Trichloroethylene

After many years of being listed as a possible or probable human carcinogen, the widely used solvent trichloroethylene (TCE) has now been listed by the National Toxicology Program (NTP) of the U.S. Department of Health and Human Services as a “known human carcinogen.” Ref; NTP’s 14th Report on Carcinogens (November 3, 2016).

Trichloroethylene is widely used in manufacturing industries as a vapour degreasing solvent but its principal uses are as an intermediate raw material in hydrofluorocarbon chemical manufacture. In the light of a number of human studies showing a causal connection between TCE exposure and an increased risk of kidney cancer, NTP re-evaluated and ultimately reclassified TCE. In addition to cancer risk, other problems that have been attributed to TCE exposure include immunotoxicity, neurotoxicity, reproductive toxicity and developmental toxicity, such as potential fetal cardiac defects.

As a known carcinogen exposure to TCE is highly regulated already in the European Union. From April 2016 its use has required authorisation for specified applications.

The ban on the use of TCE for vapour degreasing, a very widely used cleaning process, causes many problems in the engineering and manufacturing industries where oil and soils need to be removed between stages in the production processes and on finished products. The use of alternative water based cleaners are inconvenient and increase process times and costs.

A safer alternative, EnSolv is available as an established “drop in” replacement for TCE often using existing  vapour degreasing  equipment. For more information on conversion, help or advice from EnviroTech Europe Specialist team go to www.vapour-degreasing.com.

DriPHOS Metal Cleaning

DriPHOS Metal Treatment

DriPHOS Metal Cleaning – One tank cleaning and surface treatment revolutionises metal finishing.

DriPHOS TLT is a new solvent based, single tank metal cleaning and pre-treatment process developed by EnviroTech Surface Technologies which uses Thin Layer Technology to produce consistent high quality finishes.  Completely different to conventional pre-treatment processes it uses only one tank to clean, pre-treat, rinse and dry components which emerge warm to touch and with a crystalline coating on the surface which improves adhesion and protects metals against in house rusting or corrosion.    DriPHOS metal cleaning can replace current aqueous multi-tank systems reducing energy usage by at least 50%, reducing process times to 5 minute cycles, increasing throughput and uses 60%  less space releasing floor area for more productive work.

This new system will be familiar to users of the vapour degreasing process on which it is based but with the added benefit of surface pre-treatment in one tank. The  footprint of the equipment  will be the same as a vapour degreasing tank processing similar sized components.  DriPHOS TLT uses a proprietary blend of compounds in a stable low boiling point solvent carrier to dissolve the active chemicals which produce the protective crystalline structure on the metal surface.

The DriPHOS TLT metal pre-treatment process cleans surfaces to a very  high  standard   and produces a nano-thickness protective crystalline primer coating which is part of the metal surface. The coatings are extremely flexible with a very large surface area to improve the adhesion of subsequent coatings such as paint or powder coatings which are then more resistant to impact damage or scratches.

DriPHOS Metal Treatment

DriPHOS Crystal Structure magnified x 1000

The Nano thickness DriPHOS TLT crystalline coating does not change dimensions of components but flexes with the metal preventing delamination of coating films when knocked or bent which greatly increases corrosion protection compared to the random amorphous coating of conventional aqueous pre-treatments.

The very large increase in surface area is due to the unique “fish scale” structure of overlapping crystals growing from and an integral part of the metal surface. This produces more keying area priming the metal for subsequent paint, powder and other finishes to improve the adhesion of these coatings which are then more resistant to impact damage or scratches.

The DriPHOS TLT formulation has minimal environmental impact the blend of non- flammable compounds and solvents are short lived in the atmosphere and do not pose a significant potential for global warming or have an adverse effect on the ozone layer or accumulate in soils or water. Operating temperature is only 40C and no drying is required after treatment so energy usage for the whole process is very low, reducing costs and production of CO2.

Simple, sophisticated technology reduces costs while improving quality. Processed components are warm to the touch and instantly available for further fabrication, assembly or finishing. In industries such domestic and office furniture, point of sale and retail displays where small batches of different colours are needed. Stored parts will not rust or corrode for long periods under normal conditions allowing larger more cost effective batches of components to be produced.

Operators use the process safely with equipment designed to  ensure  minimal emissions or exposure to solvent.  The DRiPHOS TLT process is   simple   to   maintain   with ongoing technical support from EnviroTech partners, product specialists Fraser Technologies. Regular testing of the liquids ensures trouble free operations. Operators are trained on site to maintain the bath using the test  kits supplied and most importantly the quality control can be visually monitored instantly by the colour change on the metal surface. Iridescent blue through, gold to red instantly shows the level of crystalline coating which ensures management have complete assurance of process integrity. Price includes sample reports with regular visits by product specialists to guarantee the very highest quality of pre-treatment and final finish on products with safety for people and the environment.

CORR-EX LCP-177 Lubricant And Corrosion Inhibitor

Filed under: News — Tags: , , , — admin @ 4:27 pm
CORR-EX LCP-177

How CORR-EX LCP-177 protective lubricant prevents seizures of automatic handling systems in the harsh conditions of Industrial cleaning systems.

Specialist cleaning equipment manufacturer C&C Hydrosonics a division of U.S giant Crest Ultrasonics have solved a problem with seizures occurring the on x-y axis linear tracks on their automatic handling systems fitted to multi tank cleaning systems both aqueous and solvent based.

The automatic handling systems are programmed to process baskets or jigs through a cleaning cycle transferring between tanks, lowering and raising work from the liquids. The motorised carriages use nylon wheels running on case hardened mild steel tracks (stainless steel is not available) which corrode in the chemical atmospheres in the machine canopies.
The corrosion prevents smooth running with wheels seizing and binding on the tracks. The vibration can cause components to be shaken from jigs or in extreme cases the carriage will stall requiring intervention by service engineers to remove corrosion and re-lubricate tracks with oil. This is a temporary measure as the oil is quickly removed by the solvents and water based cleaning solutions with corrosion recurring in a short time.

CORR-EX LLC-177

CORR-EX LCP-177 from EnviroTech Surface Technologies is an innovative dry lubricant formulation  with protective properties which forms a self-healing film applied from an aerosol. The inorganic lubricant is unaffected by water and acts a barrier against rusting and corrosion. Extensive Trials by C&C Hydrosonics over a six month period with both solvent and water based systems demonstrated that CORR-EX LCP-177 offered a simple solution to the problem with no seizures during the trial period. Previously maintenance every six weeks was needed, now an aerosol spray of CORR-EX LCP-177 is used only during service  visits as a routine lubrication  and applied during production of the handling system.

Lee Casey Managing Director of C&C is delighted with the cost savings on reduced service and maintenance calls using CORR-EX LCP-177 but is even more pleased that the inconvenience to customers has been eliminated. Use of CORR-EX LCP-177  has now been extended worldwide on Crest automated handling systems.

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

The only realistic “drop in” replacement for TRIKE.

Filed under: News — admin @ 4:39 pm
 

Replace Trichloroethylene

Why EnSolv is the only realistic “drop in” replacement for TRIKE as a Vapour Degreasing Solvent.


Syd Treacher, a Surface Cleaning Consultant discusses the current controversy regarding replacements for trichloroethylene, the most commonly used vapour degreasing solvent, which was to be phased out of use in industrial applications in April  2016.

This article was prompted while reading an article where the author claimed that a grade of fluorocarbon solvent was a “drop in” replacement for TRIKE (trichloroethylene) and n- propyl bromide. This statement is not true for the majority of applications for which trichloroethylene is used – vapour degreasing or more correctly condensation cleaning.

As a consultant in surface cleaning technology I have studied the options available and come to the conclusion that the stabilised n-propyl bromide (nPB) sold in the UK under the brand name EnSolv® is the ONLY realistic “drop in” replacement for trichloroethylene when used for vapour degreasing. It is on average up to 50% cheaper than fluorocarbon formulations being proposed as alternatives.

From my evaluation it is clear current users of EnSolv® can continue to use the solvent and equipment or if still if using TRIKE you can make the change to EnSolv® in a day. A decision has to be made quickly as the “sunset date” after which TRIKE will not be available  for industrial use without authorisation in the EU was April 2016 but you can substitute with only minor changes to control settings on equipment. The legislation regarding the use of nPB may change in the future but if this happens you will have at least 3 years to decide on the alternative so the savings in solvent costs over this period will be considerable compared to alternative materials.    Read  the full article here..

Degreasing And Cleaning – Key Questions To Ask

 

There can be no doubt that manufacturers of metal components have remained keenly interested in the advantages to be found in process cleaning, while being confused by the amount of misinformation that seems presented to them.

 

There can only be two reasons for this. These is an intention to mislead or simply a lack of understanding of the subject.

In any event, the user needs to take time to match what is said to what is fact. Too often companies generalise on the basis that they are not keen for users to look deeply at the subject, yet this is vital if good decisions are to be made.

In the end, the final judgement of the user is what matters but how many people express frustration at some of the suppliers they have met who spent more time criticising a proven product rather than validating their own.

Too often, suppliers are advising what not to do rather than dealing with what really works. This is negative selling and appears on the increase as the market shrinks, regulation gets tighter and independent specialists are more limited in numbers.

Recent history suggests that larger suppliers rely on their size to justify their competence when in fact the really satisfied customers are saying smaller companies with real specialists provided the best solutions.

No one can argue against the fact that the popular choice for metal cleaning and degreasing is still vapour degreasing. This is confirmed by the companies involved in making machinery for degreasing. The order books are heavily stacked in favour of vapour degreasing. If there is one slight disadvantage currently, lead times are often 20 weeks to delivery of machines.

It is clear though that these highly cost-effective systems, which use very little solvent, are likely to remain the first choice for some considerable time.

Arguments related to the Solvent Emissions Directive carry little weight with modern machines as they are so well engineered that they are compliant with regulatory requirements. If there is one common request made by users it remains that they wish there was a single company capable of offering the total solution, e.g. both their own product and machinery together. This would shorten the circle and place more pressure on the supplier to be responsible for promises made.

Most machinery companies work with a multitude of chemistry suppliers, since they want the maximum sale of machines, but should disputes arise this can be a protracted problem as it’s easy to blame someone else for the issues involved.

Much is said about vacuum and hermetically sealed systems being the best solution. They are certainly the most expensive. Speak to an independent specialist to ensure you know the limits of these machines and the cost benefits of alternative designs.

Suppliers who claim aqueous systems are superior need to ensure they advise the user that more energy, more space, longer cleaning cycles more risk of residues and waste disposal issues should be taken into account. Global warming is an issue for all of us so factor in the amount of energy required for heating and drying. To accept that water is safer or better, needs to be well argued. Never forget that water-based cleaning solutions need changing regularly and the oils and metals produced by these processes are waste and needs correct and very expensive disposal.

When considering vapour degreasing it will often be suggested that product transfer systems attached to the existing open-topped machine bring a number of benefits. For handling benefits it is true but never doubt they will not contribute to reducing your consumption, so will do nothing for emission targets.

The best way forward is to make a supplier talk to you about their own product. Beware of those who distract you from this. If a claim is made that seems suspect, ask for the claims to be made in writing. Transparency is a vital ingredient in any relationship with your supplier.

The target audience for most suppliers are those using the carcinogen Trichloroethylene. This is now banned for general use and requires specific authorisation for use in cleaning applications. Do your research, set the questions and insist on the evidence for the arguments put forward. Protecting your business, your staff and the community around you gives a sound basis to ensure a real assessment.
