镀锌板按板面分类:有锌花镀锌板和无锌花镀锌板

Galvanized plate according to plate surface: galvanized plate and galvanized galvanized plate.

镀锌板按锌层分类有:80G锌, 100G锌,120G锌,180G锌,275G锌

Galvanized plates are classified by zinc layer: 80G zinc, 100G zinc, 120G zinc, 180G zinc, 275G zinc.

镀锌层是用电镀、热浸或喷锌的方法在基体金属表面形成的锌覆层。主要用于防止钢铁在大气中腐蚀。因锌相对于钢为贱金属,可作为牺牲阳极而对基体起到阴极保护作用。其保护能力取决于实施方法、膜层厚度及使用环境。为提高其保护能力,常配有封闭层或其他非金属面层。锌为两性金属,对酸、碱均具敏感性,镀锌层的金属应控制在中性或弱碱性环境中使用。

Galvanizing layer is a zinc cladding formed on the surface of a matrix metal by plating, hot dip or zinc spray. It is mainly used to prevent steel from corrosion in the atmosphere. Because zinc is a base metal relative to steel, it can be used as a sacrificial anode to protect the substrate by the cathode. Its protection ability depends on the implementation method, the membrane layer thickness and the use environment. To improve its protection ability, often equipped with closed layer or other non-metallic surface layer. Zinc is an amphotropic metal, sensitive to acid and alkali. Galized metal should be used in neutral or weak alkaline environment.

在我们的生活中,在很多的地方都可以看到镀锌钢板,那么为什么要采用镀锌钢板呢?

镀锌层的主要作用是隔离空气与主体的直接接触,降低氧化的速度。对于金属材质的材料来说如果材质选用不当,那么就会很快生锈,热镀锌钢板的基材是经过热镀锌的处理,因为热镀锌的锌层就是防锈的基本来源。

The main effect of the galvanizing layer is to isolate the direct contact between the air and the main body, and to reduce the rate of oxidation. For metal material, if the material is not properly selected properly, then it will soon rust, the substrate of hot galvanized steel plate is hot galvanized treatment, because the hot galvanized zinc layer is the basic source of rust prevention.

热镀锌层是使熔融金属与铁基体反应而产生合金层,从而使基体和镀层二者相结合。热镀锌具有镀层均匀,附着力强,使用寿命长等优点。

Hot-dip galvanizing layer is to make the molten metal and iron matrix reaction and produce an alloy layer, so that the substrate and the coating layer are combined. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.

而高强度镀锌和普通镀锌主要是基板有差别,高强度的抗拉强度和屈服强度都要达到500以上,高强度镀锌可以作为冲压件。

And high strength galvanizing and ordinary galvanizing is mainly the substrate difference, high strength tensile strength and yield strength should reach more than 500, high strength galvanizing can be used as stamping parts.

国内普遍的是80G锌层镀锌,材质是SGCC或DX51D

Domestic common is 80G zinc layer galvanized, the material is SGCC or DX51D

高锌层主要用于室外防腐蚀比较高的产品或室内环境湿度比较高的产品以及产品要求防腐蚀比较高的产品。低锌层主要用于室内管道以及民用,对防生锈不太注重的环节

High zinc layer is mainly used for products with high outdoor corrosion prevention or products with high indoor environmental humidity and products with high outdoor corrosion prevention requirements. Low zinc layer is mainly used for indoor pipeline and civil use, to prevent rust does not pay much attention to the link.

高强镀锌就是结构刚镀锌板,高强镀锌有强度要求一般屈服强度都在320左右或者远超这个数值,普通镀锌板卷屈服强度是没有高强镀锌大,普通的51D,抗拉强度是270-550,越往上52 53 54 56D牌号越高,越软。

High strength galvanizing is the structure of just galvanized plate, high strength galvanizing strength requirements general yield strength is about 320 or far more than this value, ordinary galvanized not galvanized strength galvanizing, ordinary 51D, tensile strength is 270-550, the higher the 52 53 54 56D brand the higher, the softer.
