Separate the metal from the environment with a physical barrier. Many corrosion inhibitors make use of this principal to protect metals. Proper use of an appropriate inhibitor may reduce or eliminate pitting. Pits are frequently initiation sites for corrosion-fatigue cracks. The effectiveness of inhibitors depends upon their application to clean metal surfaces. An example of this method is the use of zinc coatings on steel to stifle pit formation. 

A profile of methylene chloride is presented including US production capacities, demand, growth rate, price, uses, strength, weakness and outlook. Paint stripping and removal accounts for 30% of MeC by end-use application, adhesives 20%, metal cleaning 10%, aerosols 10%, pharmaceuticals 10%, chemical processing 10% and flexible PU foams 5%. Because of occupational concerns, users of MeC are under pressure to limit use, restrict... 

In the chemical industry and in research alone more than 1700 trade name products and chemicals are used as solvents (Ash and Ash, 1996). The worldwide solvents market is estimated at over 30 billions pounds per year. Solvents are used in a wide range of industries and applications including metal cleaning and degreasing, dry cleaning operations, automotive and aviation fuel additives, paints, varnishes, lacquers, paint removers, plastics and rubber products, adhesives, textiles, printing inks, pharmaceuticals, and food processing. 

Alkylphenol ethoxylates are chemically stable and highly versatile surfactants that find application in a large variety of industrial products including acid and alkaline metal cleaning formulations, hospital cleaners, herbicides (qv) and insecticides, oil-well drilling fluids, synthetic latices, and many others (see Disinfectants and antiseptics Elastomers, synthetic Insect control technology Metal surface treatments Pesticides Petroleum, drilling fluids). 

Trichloroethane is likely to enter the environment from air emissions or in wastewater from its production and use in vapour degreasing, metal cleaning and other applications. It can also enter the environment in leachates and volatile emissions from landfills. It has been detected at low levels in wastewater, groundwater, drinking-water, ambient water, ambient air, and urban air samples (United States National Library of Medicine, 1997).

There are a number of industrial applications for paraffin sulphonates, such as EOR, leather processing and metal cleaning, which exploit their high solubility, chemical stability and electrolyte tolerance. 

Like the amphoacetates and amphopropionates above, the amphohydroxypropylsulfonates are derived from hydrolyzed alkyl hydroxyethyl imidazolines. In this, amido-functional alkanolamine hydrolysis product is alkylated with sodium l-chloro-2-hydroxypropane sulfonic acid (see Figure 6.13). These products have good hard water tolerance and have applications including metal cleaning as well as personal cleansing. 

Surfactants based on aliphatic alcohols are used as cleaners in both domestic and industrial applications. They provide excellent properties such as wetting, dispersion, and emulsification. The ethoxylates derived from alkylphenols are chemically stable and highly versatile, finding more use in industrial practice than in domestic applications. They are used both as processing aids and as components in various products. Their applications include metal cleaning, hospital cleaners and disinfectants, agricultural chemical formulation surfactants, insecticides and herbicides, oil-well drilling fluids, and many others. 

Applications Mono-, di- and trisodium phosphates are used in metal cleaning, for phosphatizing, in boiler water treatment and for buffer systems e.g. in the textile industry. Disodium hydrogen phosphate is used in the food sector and in animal nutrition. 

In this review the various modes of SIMS and examples of their applications are discussed. SIMS depth profiles are widely used to study dopant profiles and Intermetallic diffusion. The extreme surface sensitivity and low concentration detection limits of SIMS make It useful for Investigation of substrate and metallization cleaning processes. SIMS elemental Imaging Is also used In contamination studies. The ability of SIMS to provide Isotopic Information has allowed elegant mechanistic studies. The Identification and determination of the relative abundance of various molecular or elemental species by SIMS Is applicable to the development characterization and understanding of microelectronic processing. The capability of SIMS In the area of quantitative analyses Is also discussed. 

These are used for preparing adhesives and for metal cleaning by removing grease, oils, dirt, etc. Trichloroethylene, toluene, xylene, ethyl acetate, methyl ethyl ketone and hexane are the most commonly used solvents in rubber lining manufacture and application. Sometimes a mixture of one or two of the above solvents is used for evaporation make up of the adhesive solutions. For closed tank linings trichloroethylene is the preferred solvents from the safety point of view. 

The group of chemical surface pretreatment methods also includes pickling. Here, thinned acids are applied, which remove layers on the metal surfaces via chemical reactions resulting in metallically clean surfaces. The respective application regulations apply, too.
