家电所用的材料品种较多，冷轧板、电镀锌板、热镀锌板、热镀锌铁合金板、彩涂板、覆膜板等均有一定的比例。

More materials used in home appliances, cold rolled plate, electric galvanized plate, hot galvanized plate, hot galvanized ferroalloy plate, color coated plate, coated plate have a certain proportion.

对面板进行处理的方法，早期采用粉末涂层的比例很高，喷粉属“后涂装”工艺，家电外壳在加工成型后喷粉涂装，其涂膜厚、成本高、效率低、花色品种单一，而且占用空间大，所以无法满足日新月异的家电市场要求。特别是由于喷粉后需要进行加热固化，所有家电厂都需建固化炉，会产生大量VOCs气体，对环境的影响较大，以此目前已经开始大批量使用彩涂板生产家电，不但可以减少家电厂的生产工序，减薄涂层，降低成本，而且便于VOCs气体的集中处理。彩涂板属于“预涂装”工艺，在家电行业称为PCM板，根据正面涂装道数划分，目前主要有一涂一烘（直接涂装面漆）、二涂二烘（底漆与面漆）和三涂三烘（底漆、面漆和罩光清漆）。

The method of treatment of the panel, the early use of powder coating proportion is very high, powder coating is a "after coating" process, home appliance shell in processing and molding powder coating, its coating thickness, high cost, low efficiency, single variety, and occupy large space, so it cannot meet the ever-changing requirements of the home appliance market.Especially because of the powder after heating curing, all power plant need to build curing furnace, will produce a large number of VOCs gas, is bigger to the influence on the environment, which has begun mass use color coating plate production home appliances, not only can reduce the production process of power plant, thinning coating, reduce costs, and facilitate the centralized treatment of VOCs gas.Color coating board belongs to the "pre-coating" process, in the home appliance industry called PCM board, according to the number of front painting road division, there are mainly one coating one drying (direct coating surface paint), two coating two drying (primer and surface paint) and three coating three drying (primer, surface paint and cover light varnish).

与PCM板相提并论的还有覆膜板，这是家电板特有的品种，是在冷轧板或镀锌板表面进行高温腹膜后获得，其装饰效果和表面质量很好，在电冰箱等产品中得到广泛应用。覆膜板又分为PVC（聚氯乙烯）膜的VCM板和覆PET（耐高温聚脂）膜的ECM面板。VCM板是在预钝化处理的钢板上涂上胶粘剂后，在一定的温度下层压PVC膜而制备。

Compared to PCM plate, there is also coated plate, which is a unique variety of home appliance plate, which is obtained after high temperature peritoneal on cold rolled sheet or galvanized sheet surface. Its decorative effect and surface quality are very good, and it is widely used in refrigerators and other products.The coated plate is divided into VCM plate covered with PVC (polyvinyl chloride) film and ECM plate covered with PET (high temperature polyester resistance) film.VCM plates were prepared by pressing the PVC film at a certain temperature after applying adhesive on pre-passivation plates.
