style="text-indent:25px">有一種處理劑的主要成分是磷酸。其中加入一些成膜劑、活性劑等物質(zhì)。這種處理劑比第一種處理劑有很大改進(jìn),一般宣稱為二合一或者四合一處理劑。它主要通過磷酸和活性劑等物質(zhì)的共同作用,在金屬外表層形成磷化膜,不但可以實現(xiàn)去油除銹的目的,同時還可以隔絕空氣,起到防銹的目的。而且使用比較方便,可以直接涂抹在金屬材料表面。但是這種處理劑也有其自身的不足,那就是這種處理劑在金屬外層形成的磷化膜是一種灰黑色的物質(zhì),手感比較粗糙,這對于那些不能改變原來顏色和手感的金屬物質(zhì),就不能使用這樣的操作方式進(jìn)行外表處理。常州低磷化學(xué)鎳藥劑價格</p><p
