一、前言聚酯漆涂层钢板是有机涂层钢板的一种,它是在钢板上辊涂聚酯漆并经烘烤固化而成的一种新型钢材料,兼有钢板和涂料二者之长,具有良好的加工成型性和耐腐蚀性;可广泛用于建筑、船舶及车辆制造等行业。二、制造过程冷轧钢板为基板的聚酯漆涂层钢板的制造过程:1、工艺流程基板→表面预处理→干燥→辊涂底漆→烘烤固化→冷却→辊涂聚酯面漆→烘烤固化→冷却。2、表面预处理工艺由于金属与有机涂料是两类完全不同的物质,二者的结合力受多种因素的影响,通过对基板进行表面预处理,可以形成一层无机盐转化膜,使基板和涂料之间有了一种双 I. Introduction Polyester lacquer coated steel plate is a kind of organic coated steel plate. It is a new type of steel material which is made of roller-coated polyester paint on the steel plate and baked and solidified, and has both steel plate and paint Long, with good formability and corrosion resistance; can be widely used in construction, shipbuilding and vehicle manufacturing industries. Second, the manufacturing process Cold-rolled steel substrate for the polyester paint coating steel manufacturing process: 1, the process of substrate → surface pretreatment → drying → primer coating → bake curing → cooling → roller coating polyester topcoat → Baking curing → cooling. 2, the surface pretreatment process As the metal and organic coatings are two completely different substances, the combination of the two factors by a variety of factors, through the substrate surface pretreatment, you can form a layer of inorganic salt conversion coating, so that the substrate There is a double between paint and paint
