我们最近发现一个问题,在小版本的新材料生产彩涂卷。随着天气越来越冷,在许多地方,不同类型的彩涂卷上出现了油漆过度爆炸的现象。这真的是天气的原因吗?事实上,这并不是全部。今天,我们来谈谈原因。
 
 
 
1.钝化板的温度生产过程要求每两小时检查一次,原因是检查时工作人员没有定期跟踪钝化板的温度。尤其在冬季,2小时内的温度变化较大,最终会导致彩涂卷老化,压印时划伤油漆。
 
 
 
2.第二步。在生产过程中,出口检查镜和一些辊上有灰尘。灰尘会直接影响彩涂卷的表面质量。它可能不会出现在开始,但一旦长时间出现,或在阳光下,油漆会发生爆炸现象。
 
 
 
三。先加入钝化液,再加水。由于钝化液的密度问题,如当钝化液的密度高于水的密度时,原料的混合物不均匀,钝化层与基体的粘附性不好,彩涂卷很容易使表面的颜色C燕麦卷爆炸。
 
 
 
彩涂卷我们应该更好地了解彩色涂料和爆炸性涂料的现象。因此,我们仍然需要规范经营,认真经营,生产出高质量的产品。
 
We have recently found a problem in the small edition of new materials for the production of colour-coated rolls. As the weather is getting colder and colder, the phenomenon of over-exploding paint appears in different types of colour-coated rolls in many places. Is this really the reason of the weather? In fact, it is not all. Today, let's talk about the reason.
 
1. Passivation plate temperature production process is required to check once every two hours, the reason is that staff did not regularly track the temperature of the passivation plate during the inspection. Especially in winter, the temperature changes within 2 hours are relatively large, which will eventually lead to the aging of the color coating roll, and scratch the paint when pressing.
 
2. In the process of production, there is dust on the exit inspection mirror and on some rolls. Dust will directly affect the surface quality of the rolls. It may not appear at the beginning, but once a long time, or in the sunshine, the phenomenon of paint explosion will occur.
 
3. Passivating liquid is added first, then water is added. Because of the density problem of passivation solution, such as when the density of passivation solution is higher than that of water, the mixture of raw materials is not uniform, and the adhesion between passivation layer and substrate is not good, so it is very easy to make the surface of color coating roll explode.
 
We should have a better understanding of the phenomenon of color coatings and explosive coatings. Therefore, we still need to standardize the operation, seriously operate, and produce high-quality products.
