腐蚀是农业机械失效的主要原因之一。涂料是防止农业机械腐蚀的最古老、同时也是应用最广泛的手段。因为,涂料施工方便,成本较低。目前,在防腐费用中,涂漆所占的比重最大,如日本在60%以上。国外农机产品采用的涂料和涂装工艺,随着石油化学工业和涂料工业的不断发展,从油性或普通醇酸涂料(手工刷涂或喷涂为主),逐渐过渡为氨基醇酸涂料(静电喷涂工艺)。60年代采用环氧酯等类水性电泳底漆,溶剂型氨基面漆。70年代以来,水性涂料、粉末涂料、高固体份涂料等发展较快。近年来,具有某
Corrosion is one of the main causes of agricultural machinery failure. Coating is to prevent the most ancient agricultural machinery corrosion, but also the most widely used means. Because, paint construction is convenient, the cost is lower. At present, the cost of anti-corrosion, paint the largest share, such as Japan in more than 60%. With the continuous development of the petrochemical industry and coating industry, the coating and coating technology adopted by overseas agricultural machinery products gradually transition from amino-acid coating to alkyd coating (mainly by manual brushing or spraying) Process). 60’s epoxy ester and other water-based electrophoresis primer, solvent-based amino finish. Since the 70s, water-based coatings, powder coatings, high-solid coatings and other rapid development. In recent years, with a certain
