家電所用的材料品種較多，冷軋板、電鍍鋅板、熱鍍鋅板、熱鍍鋅鐵合金板、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.

對面板進(jìn)行處理的方法，早期采用粉末涂層的比例很高，噴粉屬“后涂裝”工藝，家電外殼在加工成型后噴粉涂裝，其涂膜厚、成本高、效率低、花色品種單一，而且占用空間大，所以無法滿足日新月異的家電市場要求。特別是由于噴粉后需要進(jìn)行加熱固化，所有家電廠都需建固化爐，會產(chǎn)生大量VOCs氣體，對環(huán)境的影響較大，以此目前已經(jīng)開始大批量使用彩涂板生產(chǎn)家電，不但可以減少家電廠的生產(chǎn)工序，減薄涂層，降低成本，而且便于VOCs氣體的集中處理。彩涂板屬于“預(yù)涂裝”工藝，在家電行業(yè)稱為PCM板，根據(jù)正面涂裝道數(shù)劃分，目前主要有一涂一烘（直接涂裝面漆）、二涂二烘（底漆與面漆）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).

與PCM板相提并論的還有覆膜板，這是家電板特有的品種，是在冷軋板或鍍鋅板表面進(jìn)行高溫腹膜后獲得，其裝飾效果和表面質(zhì)量很好，在電冰箱等產(chǎn)品中得到廣泛應(yīng)用。覆膜板又分為PVC（聚氯乙烯）膜的VCM板和覆PET（耐高溫聚脂）膜的ECM面板。VCM板是在預(yù)鈍化處理的鋼板上涂上膠粘劑后，在一定的溫度下層壓PVC膜而制備。

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.
