镀锌瓦 波浪镀锌瓦片 铁皮




热浸镀锌钢板。将薄钢板浸入熔解的锌槽中,使其表面粘附一层锌的薄钢板。目前主要采用连续镀锌工艺生产,即把成卷的钢板连续浸在熔解有锌的镀槽中制成镀锌钢板
②合金化镀锌钢板。这种钢板也是用热浸法制造,但在出槽后,立即把它加热到500℃左右,使其生成锌和铁的合金薄膜。这种镀锌板具有良好的涂料的密着性和焊接性;

③电镀锌钢板。用电镀法制造这种镀锌钢板具有良好的加工性。但镀层较薄,耐腐蚀性不如热浸法镀锌板;

④单面镀和双面差镀锌钢板。单面镀锌钢板,即只在一面镀锌的产品。在焊接、涂装、防锈处理、加工等方面,具有比双面镀锌板更好的适应性。为克服单面未涂锌的缺点,又有一种在另面涂以薄层锌的镀锌板,即双面差镀锌板;

⑤合金、复合镀锌钢板。它是用锌和其他金属如铝、铅、锌等制成合金乃至复合镀成的钢板。这种钢板既具有卓越的防锈性能,又有良好的涂装性能;
