8910001 钢/涂层界面处的水溶性杂质对涂层寿命的影响——Morcillo M.Jorunal of the Oil & Colourchemists’ association,1988,71(1):11～17(英文) 在受污染大气侵蚀后的钢上涂漆会导致涂层的预计寿命显著缩短。大气中的SO_2和NaCl污染物可在锈中形成水溶性硫酸盐和氯化物,而这些产物引起了涂层过早变质恶化。分析了在钢/涂层界面处不同浓度的上述腐蚀促进剂对典型涂层性能的影响作用。实验是在西班牙不同的大气环境下以及在气候试验箱和盐雾试验箱中进行的。结果表明NaCl浓度仅100mg/m~2或FeSO_4浓度仅1000mg/m~2就足以使常用的涂层寿命显著缩短。另一方面,这种现象在“富锌”硅酸盐型涂层上尚未发现。8910002带烷氧基的钛酸盐和锆酸盐作涂料缓蚀剂
8910001 Effect of Water Soluble Impurities at the Steel / Coating Interface on Coating Life - Morcillo M. Jorunal of the Oil & Colourchemists’ association, 1988, 71 (1): 11-17 (English) Of the steel coating will lead to a significantly shorter life expectancy of the coating. Atmospheric SO 2 and NaCl contaminants can form water-soluble sulfates and chlorides in the rust, and these products cause premature deterioration of the coating. The effects of different concentrations of the above corrosion promoters on typical coating properties at the steel / coating interface were analyzed. Experiments were conducted in different atmospheric environments in Spain and in climate chambers and salt spray chambers. The results show that NaCl concentration of only 100mg / m ~ 2 or FeSO_4 concentration of only 1000mg / m ~ 2 is enough to make the commonly used coating life is significantly shortened. On the other hand, this phenomenon has not been found on “zinc-rich” silicate coatings. 8910002 titanate with alkoxy and zirconate as coating inhibitor
