常用的在成形前進(jìn)行預(yù)先防腐處理的板材主要有彩涂板和覆膜板兩種。在家電板材中習(xí)慣稱彩涂板為PCM，覆膜板為VCM。

The commonly used boards for pre-anticorrosion treatment before forming mainly include color coating board and film covering plate. In the home appliance plate used color coating plate for PCM, coated plate for VCM.

制作電冰箱、空調(diào)等家用電器生產(chǎn)廠在加工制作外殼中對(duì)彩涂板的彎曲成型性也十分苛刻，要求彎曲變形處涂層無裂紋，因此要求涂層的附著力較高，普通建材板上T彎≤3T即可，而家電彩涂板則要求0T。

The production of refrigerators, air conditioners and other household appliances manufacturers in the processing of the shell of the color coating plate bending molding is also very harsh, the bending deformation coating without crack, so the adhesion of the coating is higher, ordinary building materials board T can bend 3T, and home appliances color coating plate requires 0T.

顏色方面，家電彩涂板大部分白色家電板均是白色或接近白色，所以對(duì)色差要求也很嚴(yán)格。

Color respect, home appliance color is coated with board most white home appliance board is white or close to white, so to color difference requirement is very strict also.

家電板涂膜體系復(fù)雜，品種多。根據(jù)不同用途，家電板正面漆可以分為單涂層、二涂層和三涂層，對(duì)于某些特殊的產(chǎn)品甚至需要四涂層體系才能達(dá)到外觀要求。不同涂層體系的彩涂板性能相差很大。多涂層體系在外觀上和防腐性能方面要好于單涂層，但在加工性能上差些，如T彎，單涂層和雙涂層體系往往能達(dá)到0T，而且性能和粘污染性能保持良好，但三涂層體系硬度和柔韌性難以平衡。

The home appliance board coating system is complex, with many varieties. According to different uses, the front paint of the home appliance board can be divided into single coating, two coating and three coating, for some special products even need four coating system to meet the appearance requirements. The properties of the color coating plates of different coating systems vary greatly. The multi-coating system is better than the single-coating in terms of appearance and anti-corrosion performance, but worse in terms of processing performance, such as T bend, single coating and double coating system often can reach 0T, and the performance and sticky pollution performance are good, but the hardness and flexibility of the three-coating system are difficult to balance.
