广东镀锌白铁皮 家电彩涂基板无花钝化轻涂油0.35mm
镀锌钢板也叫（白铁皮）是为防止钢板表面遭受腐蚀延长其使用寿命，在钢板表面涂以一层金属锌，这种涂锌的钢板称为镀锌板。Galvanized steel plate is also called (white iron sheet) is to prevent the steel plate surface from suffering corrosion to prolong its service life, in the steel plate surface coated with a layer of metal zinc, this kind of zinc coated steel plate is called galvanized plate.空调室内机背板，柜机背板，内件，外壳，室外机内部均采用镀锌板制作，空调平均需消耗镀锌板22kg。此外，每台洗衣机消耗8公斤镀锌板，每台冰箱消耗3公斤镀锌板。汽车工业也是镀锌板消费的主要行业，其重量比家用电器重得多。Air conditioning indoor unit backplane, cabinet machine backplane, interior, shell, outdoor unit interior are made of galvanized plate, the average consumption of 22kg galvanized plate. In addition, each washing machine consumes 8 kg of galvanized plate, and each refrigerator consumes 3 kg of galvanized plate. The automotive industry is also a major sector of galvanized sheet consumption, weighing much more than household appliances.钝化镀锌板是为了减少在潮湿条件下产生白锈，在镀锌以后的产品表面进一步涂敷一层钝化保护膜。按钝化膜，的种类又分为六价铬钝化、三阶铬钝化、无铬钝化等产品，一般不用于锌铁合金板。Passivation galvanized plate is to reduce the production of white rust in wet conditions and apply a further passivation protective film on the surface of galvanized products. According to the passivation film, the types are divided into hexavalent chromium passivation, third order chromium passivation, no chromium passivation and other products, generally not used in zinc ferroalloy plate.
