Organic coatings are widely used to protect steel structures. The performance of the coating system depends upon the atmospheric conditions prevailing in the chemical industry. Before selecting a protective system, the corrosivity of the atmosphere has to be determined. A study has been made for selecting a good protective system for a soda ash chemical industry where chemicals such as soda ash, sodium chloride and hydrochloric acid are produced by using sea water as a raw material. Under these conditions, after collecting the corrosivity rate at various places of industrial areas, coated steel panels with various paint combinations were exposed in different sites for a period of 2 years. The performance of the coatings was monitored by EIS studies besides visual inspection. The corrosion protection performance of the various coating systems of zinc rich primer with different types of under coats and top coats has been studied and the results are reported. 相似文献

Calcium carbonate deposition on cotton fabric from soda ash-based detergents containing polycarboxylates is measured and related
to polymer composition and molecular weight, under varying conditions of temperature, water hardness and detergent composition.
Deposition effects on fabric are compared with threshold inhibition effects and calcium binding capacities of the polymers.
Polyacrylic acids with molecular weights of 2000–5000 are most effective in preventing calcium carbonate deposition on fabric.
A 1.5:1 acrylic acid:maleic acid copolymer is more effective than polyacrylic acid. Detergents with LAS left somewhat higher
calcium carbonate deposits than detergents with a nonionic surfactant.
Prevention of visible calcium carbonate precipitation in the absence of fabric (“threshold effects”) appears at polymer levels
considerably lower than those necessary to prevent calcium carbonate deposition on fabric. Deposition on fabric can be prevented
at levels of polymer much less than that necessary to bind most of the calcium ions, as determined by the calcium binding
capacity.
