亚博网站首页登录在使用后出现爆漆现象的原因!

来源:/ 日期:2020-07-21 发布人:jiangucaigang
亚博网站首页登录目前被广泛使用与学校、医院、产业园、娱乐场所、厂房、库房等。亚博网站首页登录是一种有着很多优秀性能的材料,同时也会有问题出现,在使用后会有爆漆的现象,那么这是什么原因造成的?
  Color steel plate is widely used in schools, hospitals, industrial parks, entertainment places, factories, warehouses, etc. Color steel plate is a kind of material with many excellent properties. At the same time, there will be problems. There will be paint explosion after use. So what is the cause?
  1、配槽时先加钝化液,后加水。由于钝化液的密度问题,比如钝化液的密度高于水的时候会造成原料混合不均匀,会出现钝化层与基板附着力不好,非常容易使彩涂卷的表面出现爆漆的现象。
  1. Add passivation solution before adding water. Due to the density problem of passivation solution, for example, when the density of passivation solution is higher than that of water, it will cause uneven mixing of raw materials, poor adhesion between passivation layer and substrate, which is very easy to cause paint explosion on the surface of color coated roll.
  2、还有钝化板温生产工艺规定是2小时检查一次,原因就是工作人员在检查的时候没有定时的对钝化板温进行跟踪。尤其是冬天的时候,2小时内温度变化也比较大,更终会造成彩涂卷时效,在压型的时候会发生划伤掉漆的现象。
  2. In addition, the production process of passivation plate temperature is stipulated to be checked once every two hours, because the staff did not track the passivation plate temperature regularly during the inspection. Especially in winter, the temperature changes greatly within 2 hours, which will eventually lead to the aging of the color coating roll, and the phenomenon of scratching off the paint will occur when pressing.
  3、在彩涂卷生产的过程中,出口检查镜上有灰尘,还有部分辊子上也有灰尘,灰尘会直接影响到彩涂卷的表面质量,或许刚开始的时候表现不出来,但是一旦时间长了,或者在阳光的暴晒下就会出现爆漆的现象。
  3. In the production process of color coating roll, there is dust on the exit inspection mirror and some rollers. The dust will directly affect the surface quality of color coating roll. It may not appear at the beginning, but once the time is long, or under the sun, the phenomenon of paint explosion will appear.
