彩钢板厂家教您如何防止一些影响产品外观的方法在生产中，消除黑点，使我们的产品更加美观。
黑点是一种在生产过程中很难发现或找不到的缺陷，它会影响后续的表面质量。黑点缺陷的研究对提高产品质量具有积极的作用。有三种典型的黑点，如下所示：
一。第一个黑点缺陷
黑点缺陷主要分布在钢带宽度方向的1/4或3/4处，沿钢带轧制方向分布。开卷后，周期性出现黑点，但周期由外圈到内圈逐渐减小，与开卷卷卷径相对应。最后，将镀锌线圈开卷到一定位置，黑点消失。
2.第二个黑点缺陷
这种黑点缺陷在开卷后没有发现，但经过深加工（冷拔、滚压）后，发现大部分零件分布在加工表面。
三。第三个黑点缺陷
黑点缺陷主要分布在钢带宽度方向的边缘，存在通带，沿钢带轧制方向呈液滴无序分布。同时，在板表面发现了摩擦痕迹。
黑点的预防措施如下：
一。规范运输和装载的防护条件，避免局部异常挤压和摩擦。
2.优化钝化工艺，确定合适的膜厚。特别是当客户对产品有冲压和拉深要求时，需要确定相应的膜厚，优化相应的工艺。
三。保护钝化剂不受飞溅的影响，避免钝化液未投入使用时落在带钢上。
知这一点，我们就能生产出更好、更完美的产品。

TangShan color coated board teaches you how to prevent some of the methods that affect the appearance of products in production, remove black spots and make our products more beautiful.

Black spot is a kind of defect which is difficult to find or can not be found in production, and it will affect the subsequent surface quality. Research on black spot defect has a positive effect on product quality improvement. There are three types of typical black spots, as follows:
1. The first black spot defect
The black spot defects are mostly distributed at 1/4 or 3/4 of the width direction of the steel band and strip distribution along the rolling direction of the steel strip. After uncoiling, black spots appear periodically, but the period decreases gradually from outer ring to inner ring, and corresponds to the diameter of uncoiling coil. Finally, galvanized coils are uncoiled to a certain position, and black spots disappear.
2. The Second Black Spot Defect
This kind of black spot defect is not found after uncoiling, but after deep processing (cold drawing, roll pressing), it is found that most of the parts are distributed on the machined surface.
3. The Third Black Spot Defect
The black spot defects are mostly distributed at the edge of the width direction of the steel band, and the pass band exists, which distributes in droplet disorder along the rolling direction of the steel band. At the same time, friction marks are found on the plate surface.
The prevention measures for black spot are as follows:
1. Standardize the protective conditions for transportation and loading to avoid local abnormal extrusion and friction.
2. Optimize the passivation process and determine the appropriate film thickness. Especially when there are stamping and drawing requirements for customers'products, it is necessary to determine the corresponding film thickness and optimize the corresponding process.
3. Protect the passivator against splash, and avoid the passivation liquid falling on the strip when it is not put into operation.
Knowing this, we can produce better and more perfect products.
