无花镀锌板按生产及加工方法可分为以下几类:①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被膜。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铅、锌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。
Flower galvanized plate can be divided into the following categories according to production and processing method: ① hot dip galvanized steel plate.
Imp the sheet into a molten zinc tank to attach a sheet of zinc to its surface.At present, the continuous galvanizing process is mainly used, that is,
the rolled steel plate is continuously immersed in the molten galvanized plating tank to make the galvanized steel plate; ② alloyed galvanized steel plate.
This plate was also made by hot dip, but immediately after leaving the trough, it was heated to about 500℃, causing it to produce an alloy coating of zinc and iron.
This galvanized plate has good coating tightness and welding properties; ③ galvanized steel plate.Making this galvanized steel plate by plating has good
machining properties.However, the coating is thin, and the corrosion resistance is less than the hot-dip galvanized plate; ④ single-sided plating and two-sided differential galvanized steel plate.Single galvanized sheet, galvanized only on one side.In welding, coating, anti-rust treatment, processing and other aspects,
it has a better adaptability than the double-sided galvanized plate.To overcome the disadvantage of no zinc coating, there is a galvanized plate with thin zinc
coating on the other surface, namely double-sided differential galvanized plate, ⑤ alloy and composite galvanized steel plate.It is made of alloy and even
composite plating with zinc and other metals such as lead and zinc.This steel plate has both excellent rust resistance and good coating performance.
