鍍錫。錫具有銀白色的外觀，原子量為118.7，密度為7.3g/cm^3，熔點(diǎn)為231.89℃，原子價(jià)為二價(jià)和四價(jià)，故電化當(dāng)量分別為2.12g/A.h和1.107g/A.h。錫具有抗腐蝕、無毒、易鐵焊、柔軟和延展性好等優(yōu)點(diǎn)。錫鍍層有如下特點(diǎn)和用途： </p> <p> 1、化學(xué)穩(wěn)定性高； </p> <p> 2、在電化序中錫的標(biāo)準(zhǔn)電位紕鐵正，對鋼鐵來說是陰極性鍍層，只有在鍍層無孔隙時才能有效地保護(hù)基體； </p> <p> 3、錫導(dǎo)電性好，易焊； </p> <p> 4、錫從-130℃起結(jié)晶開始開始發(fā)生變異，到-300℃將完全轉(zhuǎn)變?yōu)橐环N晶型的同素異構(gòu)體，俗稱”錫瘟”，此時已完全失去錫的性質(zhì)； </p> <p> 5、錫同鋅、鎘鍍層一樣，銅排鍍錫表面處理加工，在高溫、潮濕和密閉條件下能長成晶須，稱為長毛；6、鍍錫后在231.89℃以上的熱油中重溶處理，可獲得有光澤的花紋錫層，銅排鍍錫表面處理加工，銅排鍍錫表面處理加工，可作日用品的裝飾鍍層，上海眾霖五金有限公司為上海眾新五金有限公司下屬子公司，主要從事各類金屬零件電鍍業(yè)務(wù)，其鍍種主要有：鍍鋅、鋅鎳合金、化學(xué)鍍鎳、電鍍鎳、鍍金、鍍銀、鍍錫等。如您需要鍍錫業(yè)務(wù)，請聯(lián)系我們。
