首先，我们需要知道什么是锌花，它是钢板热浸镀层凝固过程中金属表面镀层的结晶形态。在了解了什么是彩涂板锌花后，进入本文的主要话题，本文主要探讨了锌花的形成，让我们有所了解。

一。喷水：当锌层表面的纯锌溶液凝固时，由于细水雾（水和水蒸汽或水和空气的混合物）的作用而成核。未凝固的液态锌扩散形成锌花。
2。表面吹塑法：当彩色镀锌板上的纯锌层凝固时，如果锌晶体能使表面通过蒸汽流或二氧化硫流顺利生长，则可获得大的图案。该方法还可以形成高密度的空气氧化膜，提高锌镀层的耐蚀性。
三。钢丝网法：本方法仅适用于镀锌钢板。它是用来将钢丝网与锌层和磁辊表面接触来达到这一目的的。由于钢网节点的接触部分首先冷却，节点中的固体颗粒首先形成晶核。另一种非凝固锌液，即晶核开始向外膨胀形成锌花。
锌花的生产关系到成品的质量。在彩色印刷铜版纸上制作大型锌花，应考虑多种因素。

First of all, we need to know what is zinc flower, which is the crystal pattern of coating metal on the surface of hot-dip coating of steel plate during solidification. After understanding what is the color coated plate zinc flower, enter the main topic of this paper, this paper mainly discusses the formation of zinc flower, let's get to know.

1. Water spray: when the pure zinc solution on the surface of zinc coating solidifies, the nucleation is caused by water mist (water and steam or mixture of water and air). The non solidified liquid zinc diffuses to form zinc flower.

2. Surface blow molding method: when the pure zinc layer on the color galvanized sheet is to be solidified, if the zinc crystal can make the surface grow smoothly through steam flow or sulfur dioxide flow, large patterns can be obtained. The method can also form high density air oxidation film and improve the corrosion resistance of zinc coating.
3. Wire mesh method: this method is only applicable to galvanized steel plate. It is used to contact the steel wire mesh with the surface of zinc layer and magnetic roller to achieve this purpose. Because the contact part of the steel mesh node first cools, the solid particles in the node first form crystal nucleus. Another kind of non solidified zinc liquid, namely, the crystal nucleus begins to expand outward to form zinc flower.
The production of zinc flower is related to the quality of finished products. Many factors should be taken into consideration when making large-scale zinc flowers on the printed color coated paper.
