【真(zhen)空(kong)镀(du)(du)膜机之真(zhen)空(kong)电(dian)镀(du)(du)】真(zhen)空(kong)电(dian)镀(du)(du)是一(yi)种物理沉(chen)积现(xian)象。即(ji)在真(zhen)空(kong)状态下注入氩(ya)气，氩(ya)气撞击(ji)靶材(cai)，靶材(cai)分(fen)离成分(fen)子被导电(dian)的货(huo)品吸(xi)附形成一(yi)层均匀光(guang)滑(hua)的仿金属表面层。 适(shi)用材(cai)料(liao)： 1、很多材(cai)料(liao)可以进(jin)行真(zhen)空(kong)电(dian)镀(du)(du)，包括金属，软(ruan)硬塑料(liao)，复合材(cai)料(liao)，陶瓷和玻璃。其中(zhong)*常见用于电(dian)镀(du)(du)表面处理的是铝材(cai)，其次是银和铜。 2、自然材(cai)料(liao)不适(shi)合进(jin)行真(zhen)空(kong)电(dian)镀(du)(du)处理，因为自然材(cai)料(liao)本(ben)(ben)(ben)身的水(shui)分(fen)会影响真(zhen)空(kong)环境。 工艺成本(ben)(ben)(ben)：真(zhen)空(kong)电(dian)镀(du)(du)过程中(zhong)，工件需要喷涂(tu)，装载，卸载和再喷涂(tu)，所以人(ren)力成本(ben)(ben)(ben)相(xiang)当高(gao)，但(dan)是也取决于工件的复杂度和数量。 环境影响：真(zhen)空(kong)电(dian)镀(du)(du)对环境污染很小，类似于喷涂(tu)对环境的影响。国产真(zhen)空(kong)镀(du)(du)膜机厂商推荐(jian)。上海真(zhen)空(kong)镀(du)(du)膜机什么品牌(pai)好
