当今世界随着民用建筑业、运输业、电器业及日用工业等部门的急剧发展,对各种涂层钢板的需求与日俱增.据不完全统计,至1981年为止,全世界约有涂层作业线二百余条,总产量六百万吨以上,还有继续猛增的趋势.众所周知,涂层钢板大致可分为有机涂层钢板、无机涂层钢板和复合涂层钢板三种类型,而使用寿命能保证在15年甚至20年以上的合成树脂等涂层钢板是需求量最大的一种,其中有六种产品已大量投入市场销售.这六种产品是: 1.聚氯乙烯薄膜层压钢板; 2.丙烯酸薄膜层压钢板; 3.聚氟树脂涂层钢板; 4.聚氯乙烯复合薄膜层压钢板; 5.聚氟、聚氯乙烯复合薄膜层压钢板; 6.沥青浸渍石棉层压钢板. 目前,国外生产的有机涂层钢板、无机涂层钢板和生产采用的原板.对有机涂层钢板使用的有机材料,现在随着高分子化学的发展,涂层方法的改进,实际上可以提供各种各样的有机材料.
In today’s world, with the rapid development of civil construction, transportation, electrical appliances and daily use industries, the demand for various coated steel plates is increasing .According to incomplete statistics, until 1981, there are about coating operations in the world Line more than 200, the total output of more than 6 million tons, there are continuing to surge.As we all know, coated steel can be divided into three types of organic coated steel, inorganic coated steel and composite coated steel, and The service life can guarantee 15 years or even more than 20 years of synthetic resin coating steel is the most in demand, of which six kinds of products have been put into the market a lot. These six products are: 1. PVC film layer Plating; 2. Acrylic film laminated steel; 3. Polyfluoro resin coated steel; 4. PVC composite film laminate steel; 5. Poly fluorine, PVC laminated film laminate steel; 6. Asphalt impregnated asbestos At present, foreign production of organic coated steel, inorganic coated steel and the production of the original board. Organic materials used in organic coated steel, now with the development of polymer chemistry, coating methods to improve the actual Various can be provided on the Organic material.
