Why are there pressure spots on the surface of fireproof color steel plate? Today, Xiaobian will analyze it specifically for you. I hope it will be helpful to you.

防火彩钢板在剪切使用时，表面时常会出现一种缺陷——表面压斑缺陷，该缺陷是彩涂板涂层烘烤、冷却后卷取时，由于卷取张力导致涂层表面的轻微变形，有时表面呈现出粗糙,表现出了视觉可见的压斑形态。这是什么原因造成的呢?

When the fireproof color steel plate is cut and used, there is often a defect on the surface - surface pressure spot defect. This defect is the slight deformation of the coating surface caused by the coiling tension when the color coated plate coating is baked and cooled. Sometimes the surface is rough, showing a visually visible pressure spot shape. What causes this?

轻微的压斑缺陷会随防火彩钢板存放时间的延长而逐渐消失，经过加热也可去除。但是较为严重的压斑缺陷即使采用上述措施也不能解决，从而影响用户使用。防火彩钢板压斑是生产过程中产生的一种缺陷，若是在生产过程中寻找产生这种缺陷的原因及影响因素，需要经过多次停机查排，影响生产计划，提高生产成本。因此需要通过实验室模拟、复制这种缺陷，并对其进行评价，从各个方面寻找产生缺陷的原因与影响这种缺陷的因素。

Slight pressure spot defects will gradually disappear with the extension of storage time of fire-resistant color steel plate, and can also be removed after heating. However, the more serious pressure spot defect can not be solved even with the above measures, which affects the use of users. Fire color steel plate plaque is a defect in the production process. If the causes and influencing factors of this defect are found in the production process, it needs to be stopped for many times, which will affect the production plan and improve the production cost. Therefore, it is necessary to simulate, copy and evaluate this defect in the laboratory to find the causes and factors affecting this defect from all aspects.
