style="text-indent:25px">化學(xué)鍍鎳在金屬表的應(yīng)用：乳狀液型防銹劑。乳狀液型防銹劑有二種:一種是油的顆粒在水中的混液，即水包油型乳化油，一般呈奶白色;另一種是水的顆粒在油中的混液，即油包水型乳化油，一般是全透明的或透明色的液體。乳狀液型防銹劑既具備防銹處理特性，又具備潤(rùn)濕性能和制冷特性，因而常見(jiàn)作金屬材料鉆削生產(chǎn)加工工的潤(rùn)化冷凍液。乳狀液型防銹劑中的破乳劑以往常見(jiàn)油脂經(jīng)皂腳生產(chǎn)加工而成，近些年則應(yīng)用脂肪酸三乙醇胺、磺化油或者非正離子表活劑等。以便提升防銹處理特性，在放水配制成乳化油時(shí)，還可添加一定量的水溶防銹劑，如亞硝酸鈉與碳酸鉀、亞硝酸鈉與三乙醇胺等。除此之外，以便避免和緩解乳化油發(fā)出臭味霉變，還可添加小量除霉劑，如甲酸、五氨酚、苯甲酸鈉等。化學(xué)鍍鎳的電流來(lái)自化學(xué)反應(yīng)，而不是由外電源提供。義烏化學(xué)鍍鎳后處理</p><p
