采用塑料涂层防止汽车生锈的两项新技术正在美国进行试验:一种方法是用粉末聚酯;另一种方法是用聚氯乙烯基塑料溶胶,这种塑料溶胶多来一直被用作家用地板砖的耐磨顶层涂料。聚酯涂层不是靠使用喷涂法和浸渍法,而是靠采用静电技术镀上去的。操作时,让聚 Two new technologies that use plastic coatings to prevent rusting of automobiles are being tested in the United States: one is to use powdered polyester; the other is to use a polyvinyl chloride-based plastisol, which has been used for many years Floor tiles wear-resistant top coating. Polyester coating is not by using the spray method and impregnation method, but by using electrostatic plating technology. When operating, let gather
