彩涂板在日常使用中为什么会爆漆

彩涂板在我们的生活中得到了广泛的应用,这种产品在使用过程中,有时会出现油漆爆炸的现象,造成这种现象的原因是什么?在彩色涂布机表面涂布2号水淬盖板槽时,发现有淤泥和灰尘, 彩涂板出口检查镜上有灰尘,部分辊子表面也有浮尘。粉尘会影响山东彩涂板的表面质量,尤其是老化爆漆的质量缺陷。钝化板温度生产过程每2小时调节一次,不实时跟踪钝化板温度。

彩涂板环境温度为10℃ 在冬季,环2122112的温度变化可能导致钝化后2小时内的温度变化,最终导致山东彩涂板老化和成型过程中油漆划伤。加水前加钝化液。当钝化液的密度高于水的密度时,会造成混合不均匀,钝化层与基体的附着力差,容易造成面漆质量缺陷。


Color coated board has been widely used in our life, this product operation, but in the process of use, sometimes appear the phenomenon of paint explosion, what are the reasons for this phenomenon? When No. 2 water quenched cover plate slot was coated on the surface of color coating machine, silt and dust were found, dust was found on the exit inspection mirror, and floating dust was also found on the surface of some rollers. Dust will affect the surface quality of Shandong color coated sheet, especially the quality defects of aging paint explosion. The production process of passivation plate temperature is regulated to check every 2 hours, and the passivation plate temperature is not tracked in real time.

When the ambient temperature is 10 ℃ in winter, the temperature change of ring 2122112 may cause the temperature change after passivation within 2 hours, which eventually leads to the aging of Shandong color coated plate and the scratch of paint during the molding. Add passivation solution before adding water. When the density of passivation solution is higher than that of water, it will cause uneven mixing, poor adhesion between passivation layer and substrate, and easy to cause quality defects of top coat.
