实用涂料防腐蚀技术问答 总被引:4,自引:0,他引:4
实用涂料防腐蚀技术问答王泳厚(广州制漆厂,510380)6防腐蚀涂料如何分类从涂料的保护作用来看,常分为防锈涂料和防腐蚀涂料两大类。防锈涂料就是用于防止钢铁受自然因素锈蚀的各种底漆。而防上钢铁受化学介质或化学烟雾腐蚀的各种涂料,则称为防腐蚀涂料。按照... 相似文献

Comparison of the efficiency of inorganic nonmetal pigments with zinc powder in anticorrosion paints
This paper deals with the study of properties of anticorrosion pigments of varying chemical composition in epoxyester paints. Two type lines of paints were prepared. The first line comprised an anticorrosion pigment with a PVC concentration of 10% while the other line comprised an anticorrosion pigment with a PVC concentration = CPVC. The following nontoxic anticorrosion pigments were observed: zinc phosphate, zinc phosphomolybdate, calcium hydrogen phosphate, zinc phosphate modified with an organic corrosion inhibitor, strontium–aluminum polyphosphosilicate, zinc–aluminum polyphosphate, calcium metaborate, calcium ferrite, calcium borosolicate, and strontium chromate. The epoxyester primers were observed for the effect of the type of pigment on the anticorrosion properties. Anticorrosion efficiency was derived from tests in a condenser chamber and in a salt spray cabinet as well as from a test of chemical resistance of pigmented coatings. The evaluation of anticorrosion efficiency of inorganic nonmetal pigments was carried out by means of comparison with anticorrosion efficiency of metal dust. 相似文献
