除了工艺控制和涂装外，选择优质、合格的基材是生产高品质、高端定制彩涂板——家电彩涂板的另一个非常重要的条件。如果原板表面存在缺陷，通常很难依靠20微米以上的涂层来弥补缺陷。





目前，在 家电彩涂板厂家的实际生产过程中，由于工艺基本固定，原有色板的质量已上升为影响产品最终质量的最重要问题。下面介绍了目前应用最广泛的家电彩涂板厂家生产的家用电器彩涂板的表面热镀锌检测方法。一般家用电器面板应按表面无明显缺陷的标准进行检查验收。常见的缺陷有：印痕、滚印、滚印、划痕、镀后划痕、气刀痕、锌痕波纹。锌渣、污垢（油或其他污水）、装饰花、羽毛、折痕、水印、锌花、亮边、锌灰等。





在上述缺陷中，一般的非 定制彩涂板厂家由于热镀锌线中异物的挤压，很难直接用肉眼观察到带钢表面的许多明显凹陷或突起，但涂漆后，压痕上会出现色差点。部分原因。因此，来料应通过油石研磨进行检查。抛光检查在水平检查平台上进行。下表面和上表面应分开。抛光油石应均匀地铺在钢板上。抛光力不要太重。用油石将镀锌板表面抛光后，一些非常细的凹凸点会变成暗点或亮点。很容易发现。在光线充足的环境下，将钢板从侧面向前倾斜30度，检查钢板表面是否有凹凸痕迹或其他不可检测的缺陷。应采用抛光时发现缺陷的检验方法。当发现可疑缺陷时，应及时在缺陷上做标记。如果发现周期性压印，应测量边缘与两点之间的距离，暂时不应闭合线圈。

因此，很有必要选择一家正规的彩涂板厂家来定制家电彩涂板。天物彩板多年来一直从事高端彩涂板定制。他们质量好，经验丰富。欢迎购买！

In addition to process control and coating, another very important condition for producing high-quality and high-grade color coated panel for household appliances is to select high-quality and qualified substrate. If there are defects on the surface of the original plate, it is often difficult to make up for the defects by relying on a coating of more than 20 microns.



At present, in the actual production process of color panel for household appliances, the quality of the original panel has risen to be the most important problem affecting the final quality of the product because the process has been basically fixed. Following is an introduction of how to inspect the surface of the color coated panel of household appliances by hot-dip galvanizing, which is the most widely used substrate at present. Usually, the panel of household appliances should be checked and accepted according to the standard of no obvious surface defect. The common defects are: impression, roll print, roll mark, scratch, scratch after plating, air knife mark, zinc mark ripple. Zinc dregs, dirt (oil or other sewage), finishing flowers, feathers, creases, watermarks, zinc flowers, bright edges, zinc ash, etc.



Among the defects mentioned above, it is difficult to observe directly with the naked eye many obvious depressions or protrusions on the surface of strip steel due to the extrusion of foreign bodies in hot galvanizing line, but after painting, there will be spots of color difference on the impression part. Therefore, the incoming materials should be checked by oil stone grinding. The polishing inspection is carried out on the horizontal inspection platform. The lower surface and the upper surface should be separated. The polishing oil stone should be evenly laid on the steel plate. The polishing force should not be too heavy. After polishing the surface of galvanized sheet with oil stone, some very fine concave and convex spots will become dark spots or bright spots. It is easy to find out. Under the full light environment, the steel plate will be angled 30 degrees from the lateral and forward to the horizontal plane to check whether there are concave and convex marks or other undetectable defects on the surface. The inspection method of finding defects while polishing should be adopted. When suspected defects are found, marks should be made on the defects in time. If periodic imprinting is found, the distance between edge and two points should be measured, and the coil should not be closed for the time being.



Therefore, it is very necessary to choose a regular color coated plate manufacturer. Qianye new building materials have been engaged in color coated plate production for many years. They are of good quality and have rich experience. Welcome to buy them!
