镀锌板大锌花、小锌花的区别

正常锌花(小锌花、大锌花、无锌花)热镀锌钢板是热镀锌钢板在锌液含锑或铅的条件下热浸镀后,在正常凝固过程中,锌晶粒自由长大形成的具有明显锌花形貌的镀层板。正常热镀锌钢板主要以裸露的方式使用,有锌花镀锌板和没锌花镀锌板只是外观区别,没有质量区别。

所以,小锌花、大锌花、无锌花)热镀锌钢板的用途是一样的。

一、无锌花热镀锌钢板
在锌液中添加锌花促进元素,锌层凝固时没有锌花形成,晶粒很细,光洁平整,因而叫无锌花产品。其耐腐蚀性能优越,涂装性能较好。
二、大锌花热镀锌钢板
在锌液中添加了锌花促进元素,因而镀层凝固时形成了美丽的锌花。在使用初期外观性能较好,但晶粒粗大,存在细微的凹凸不平。
三、小锌花热镀锌钢板
小锌花产品并没有严格的定义,一般只是将锌花小一些的产品叫小锌花产品。小锌花产品是以大锌花产品同样的成分,为了克服大锌花产品涂装性能不好的缺陷,在冷却时采用各种办法来抑制锌花的长大,最好形成直径很小的锌花。由于它既不像大锌花那样具有镜面的光滑表面,又不像无锌花产品那样很光洁,所以涂装性能很好。

Normal zinc flower (small zinc flower, large zinc flower, no zinc flower) hot-dip galvanized steel plate is a kind of plating plate with obvious zinc flower shape formed by free growth of zinc grains in the normal solidification process after hot-dip galvanized steel plate with antimony or lead in the zinc solution. The normal hot-dip galvanized steel plate is mainly used in the exposed way. The galvanized plate with zinc flowers and the galvanized plate without zinc flowers are only different in appearance and quality.

Therefore, small zinc flower, large zinc flower and no zinc flower) the purpose of hot-dip galvanized steel plate is the same.
1、 Zinc free hot dip galvanized steel sheet
When zinc layer is solidified, there is no formation of zinc flower. The grain is very fine and smooth, so it is called non zinc flower product. It has excellent corrosion resistance and good coating performance.
2、 Large zinc flower hot galvanized steel plate
In the zinc bath, the element of zinc flower is added to promote the formation of beautiful zinc flower when the coating solidifies. In the early stage of use, the appearance performance is good, but the grains are coarse and there are fine unevenness
3、 Small zinc flower hot-dip galvanized steel plate
There is no strict definition of small zinc flower products. Generally, small zinc flower products are called small zinc flower products. In order to overcome the defects of poor coating performance of large zinc flower products, various methods are used to inhibit the growth of zinc flower during cooling, and it is best to form zinc flower with small diameter. Because it is not as smooth as the mirror surface of the big zinc flower, nor as smooth as the non zinc flower products, so the coating performance is very good.
