镀锌彩钢板有哪些种类 镀锌板和不锈钢彩钢板有什么区别?

镀锌板彩钢板:镀锌板是指表面有一层锌的钢板。镀锌是常用的一种经济有效的防锈方法。世界上大约一半的锌生产都用在这一过程中。
不锈钢:不锈钢是不锈钢的缩写,它能抵抗空气、蒸汽、水等弱腐蚀性介质,或不锈钢;具有耐化学腐蚀(酸、碱、盐和其他化学腐蚀)的钢称为钢。

有什么镀锌板
1热镀锌板彩钢板。一种薄钢板,其表面附着一层锌,将其浸入熔融锌浴中。目前主要采用连续镀锌工艺,即将轧制钢板连续浸入熔锌槽中,制成镀锌钢板;
2合金镀锌板彩钢板。这种钢板也采用热浸法,但出槽后立即加热到500℃左右,形成锌铁合金膜。镀锌板具有良好的涂层附着力和焊接性;
三。电镀锌钢板。这种镀锌钢板具有良好的加工性能。但镀层较薄,耐蚀性不如热镀锌板;
4单面镀双面差热镀锌钢板。单面镀锌钢板,即只有单面镀锌产品。在焊接、涂装、防锈处理、加工等方面均优于双面镀锌板。为了克服单面未镀锌的问题,另一种镀锌板在另一面涂上一层薄薄的锌;
5合金,复合镀锌钢板。它由锌和其他金属制成,如铝、铅、锌等,甚至是复合镀层钢板。这种钢板不仅具有优良的防锈性能,而且具有良好的涂装性能;

Galvanized sheet: galvanized sheet refers to the steel plate with a layer of zinc on its surface. Galvanizing is an economical and effective antirust method which is often used. About half of the world's zinc production is used in this process.


Stainless steel: stainless steel is the abbreviation of stainless steel, which is resistant to weak corrosive media such as air, steam, water, etc., or stainless steel; and the steel with chemical corrosion resistance (acid, alkali, salt and other chemical etching) corrosion is called steel.

What kinds of galvanized sheet are there

1. Hot dip galvanized steel plate. A thin steel sheet with a layer of zinc adhered to its surface by immersing it in a molten zinc bath. At present, continuous galvanizing process is mainly used, that is, the rolled steel plate is continuously immersed in the bath with zinc melting to make galvanized steel plate;

2. Alloyed galvanized steel sheet. This kind of steel plate is also made by hot-dip method, but it is heated to about 500 ℃ immediately after it is out of the groove to form alloy films of zinc and iron. The galvanized sheet has good coating adhesion and weldability;

3. Electro galvanized steel sheet. This kind of galvanized steel plate has good processability. However, the coating is thinner and its corrosion resistance is not as good as that of hot dip galvanized sheet;

4. Single side plating and double side differential galvanizing steel plate. Single side galvanized steel sheet, that is, only one side galvanized products. It has better adaptability than double-sided galvanized sheet in welding, coating, antirust treatment and processing. In order to overcome the point that one side is not coated with zinc, there is another kind of galvanized sheet coated with a thin layer of zinc on the other side;

5. Alloy, composite galvanized steel sheet. It is made of zinc and other metals, such as aluminum, lead, zinc, etc., and even composite plated steel plate. This kind of steel plate not only has excellent antirust performance, but also has good coating performance;
