探讨镀锌钢板的归类有什么镀锌板表层镀有一层锌的厚钢板

镀锌板是一种表面有一层锌的厚钢板。热浸镀锌是一种经济发展合理的防锈处理方法。世界上大约一半的锌产量用于这种加工技术。那么镀锌钢板的分类是什么呢?镀锌钢板制造商告诉你。

按制造加工方法可分为以下几类:
① 热浸镀锌板。冷轧钢板渗入熔融锌浴中
表面有一层锌的冷轧钢板。现阶段的关键是采用连续热镀锌工艺制造,即将厚钢板连续浸入熔锌槽中制成镀锌钢板;
② 细晶粒强化镀锌钢板。这种厚钢板是用热浸法生产的,但从罐中排出后,立即加热到500℃,变成锌铁铝合金塑料膜。这种镀锌板对建筑涂料具有良好的附着力和焊接性;
镀锌板。这种电镀生产的镀锌钢板具有优良的工艺性能。但镀层较薄,耐蚀性不如热镀锌板;
④ 单面和双面电镀和双面差异镀锌板。单面和双面镀锌钢板,即只有单面热浸镀锌的货物。在焊接、喷涂、防锈、生产加工等方面,比两侧镀锌板具有更强的适应性。
为了消除两侧未镀锌的缺陷,另一侧有另一种镀锌板,即两侧有差异的镀锌板;
⑤ 铝合金复合镀锌钢板。它由锌和其他金属材料制成,如铝、铅、锌等。它是由铝合金,甚至复合镀厚钢板。这种厚钢板不仅具有特殊的防锈处理特性,而且具有优良的喷涂特性;
除五彩镀锌钢板外,还有彩色镀锌钢板、服装印花喷涂镀锌钢板、聚乙烯层压镀锌钢板等,但现阶段最常见的还是热镀锌钢板。主要制造商和进口国:
① 国内重点生产企业:武钢、首钢、鞍钢黄石、中冶恒通、首钢、攀枝花钢铁、邯郸钢铁、马鞍山钢铁、福建开京等;
② 日本、法国、乌克兰、荷兰、日本等是海外的主要制造国。

Galvanized sheet is a thick steel plate with a layer of zinc on the surface. Hot dip galvanizing is a kind of economic development and reasonable antirust treatment. About half of the world's zinc production is used for this kind of processing technology. So what is the classification of galvanized steel sheet? The manufacturer of galvanized steel sheet tells you.

According to manufacturing and processing methods, it can be divided into the following categories:
① Hot dip galvanized steel plate. The cold rolled steel sheet is infiltrated into the molten zinc bath
A cold rolled steel plate with a layer of zinc adhered to its surface. At the present stage, the key is to use continuous hot-dip galvanizing process to manufacture, that is, to continuously immerse the plate of thick steel in the bath with molten zinc to make galvanized steel plate;
② Fine grain strengthening galvanized steel sheet. This kind of thick steel plate is produced by hot-dip method, but after it is discharged from the tank, it is heated to 500 ℃ immediately to convert it into aluminum alloy plastic film of zinc and iron. This kind of galvanized sheet has excellent adhesion and weldability of architectural coatings;
③ Galvanized steel sheet. This kind of galvanized steel sheet produced by electroplating has excellent technological properties. However, the coating is thin and its corrosion resistance is not as good as that of hot dip galvanized sheet;
④ Single and double side plating and double side difference galvanized steel sheet. Single and double-sided galvanized steel sheet, that is, only on one side of the hot-dip galvanized goods. In welding, spraying, rust prevention, production and processing, it has stronger adaptability than galvanized sheet on both sides.
In order to get rid of the defect of uncoated zinc on both sides, there is another kind of galvanized sheet coated with chromatographic zinc on the other side, that is, galvanized sheet with difference between two sides;
⑤ Aluminum alloy, composite galvanized steel sheet. It is made of zinc and other metal materials, such as aluminum, lead, zinc and so on. It is made of aluminum alloy and even composite plated thick steel plate. This kind of thick steel plate not only has special anti rust treatment characteristics, but also has excellent spraying characteristics;
In addition to the five, there are also colorful galvanized steel sheets, clothing printing spraying galvanized steel sheets, polyethylene laminated galvanized steel sheets, etc. But at this stage the most common is still hot-dip galvanized sheet. Key manufacturers and importing countries:
① Key manufacturers in China: WISCO, Shougang, Angang Huangshi, MCC Hengtong, Shougang, Panzhihua Iron and Steel Co., Ltd., Handan Iron and Steel Co., Ltd., Maanshan Iron and Steel Co., Ltd., Fujian Kaijing, etc;
② Japan, France, Ukraine, the Netherlands, Japan, etc. are the key manufacturing countries overseas.
