镀锌彩涂板要注意涂料的选择
1、 一般来说，可根据制造商的标准颜色选择彩色涂层镀锌板，这可以缩短生产初期的工作量。如果需要特殊颜色，则只有在涂料制造商准备好样品且所有性能满足要求后才能生产涂料，因此从订购到彩色涂层板的生产时间将更长。
2、 通过60度反射角测量的涂层表面光泽度越高，光泽度越高。建筑涂料为中哑光，范围为30至55。这是因为高光泽涂料对建筑物内的阳光具有强烈的反射和眩光；如果你在室内，晚上在灯光下很容易引起视觉疲劳。
3、 彩色涂层镀锌板的涂层采用合成树脂涂层烘烤。当在室外使用时，由于阳光、温度和雨水的影响，薄膜会逐渐劣化。如果你仔细观察钢板表面或用手指轻轻触摸，你会发现白色粉末。这种现象就是薄膜的粉碎，这是不可避免的。
4、 彩色镀锌板应选择不同类型的涂层，以延迟粉碎时间。此外，在不同地区，如沿海地区、工业区和农村地区，其使用寿命也不同。如果出现涂层粉化、开裂等腐蚀，应重新喷涂，以延长使用寿命。
锌花是指在镀锌板生产过程中，通过降低镀锌板的凝固温度，使彩涂镀锌板凝固。锌花是如何形成的？作为彩色涂层镀锌板的制造商，让我们解释一下锌花的形成过程：
1.钢板与锌的界面出现不均匀形核。
① 这个过程需要很短的时间（不超过百分之几秒），但锌花的最终形状和大小已经确定。
② 批量晶体沿钢板/锌界面快速生长，直至覆盖整个表面，而表面仍为液态。
2.第二阶段为n层枝晶增厚过程，缓慢。择优取向的枝晶生长迅速，溶质元素在枝晶前析出。当达到空气/锌界面时，锌枝晶停止凝固。
① 镀锌板，锌花在镀锌板表面形成的方式决定了锌花的灰色外观。
② 富含溶质元素的残余液相的凝固过程。
1、 Generally speaking, the color coated galvanized sheet can be selected according to the manufacturer's standard color, which can shorten the workload in the early stage of production. If a special color is required, the coating can be produced only after the coating manufacturer has prepared samples and all properties meet the requirements, so the production time from ordering to color coated plate will be longer.
2、 The higher the gloss of the coating surface measured by the 60 degree reflection angle, the higher the gloss. The architectural coating is medium matte, ranging from 30 to 55. This is because the high gloss coating has strong reflection and glare to the sunlight in the building; If you are indoors, it is easy to cause visual fatigue under the light at night.
3、 The coating film of color coated galvanized sheet is baked with synthetic resin coating. When used outdoors, the film will deteriorate gradually due to the influence of sunlight, temperature and rain. If you carefully observe the surface of the steel plate or touch it gently with your fingers, you will find white powder. This phenomenon is the pulverization of the film, which is inevitable.
4、 Different types of coatings shall be selected for color coated galvanized sheet to delay the pulverization period. In addition, it has different service life in different areas such as coastal areas, industrial areas and rural areas. In case of corrosion such as coating pulverization and cracking, re spraying shall be carried out to prolong the service life.
Zinc flower refers to the solidification of color coated galvanized sheet by reducing the solidification temperature of galvanized sheet in the production process of galvanized sheet. How is zinc flower formed? As a manufacturer of color coated galvanized sheet, let's explain the formation process of zinc flower:
1。 Uneven nucleation occurs at the interface between steel plate and zinc.
① This process takes a short time (no more than a few percent of a second), but the final shape and size of the zinc flower have been determined.
② Batch crystals grow rapidly along the steel plate / zinc interface until they cover the whole surface, while the surface is still liquid.
2。 The second stage is the n-layer dendrite thickening process, which is slow. The dendrite with preferred orientation grows rapidly and solute elements precipitate in front of the dendrite. When the air / zinc interface is reached, the solidification of zinc dendrites stops.
① Galvanized sheet, how zinc flowers are formed on the surface of galvanized sheet determines the gray appearance of zinc flowers.
② Solidification process of residual liquid phase rich in solute elements.
