山东彩涂卷在生产过程中出现塌卷原因

山东彩涂卷在生产过程中,难免会出现问题,很多厂家在生产彩涂卷材时出现塌板现象,这是一开始就头疼的问题,那么造成彩涂卷材厂家在生产工程中出现这种现象的原因是什么呢?

山东彩涂卷造成折叠现象的直接原因是色板卷曲和展开(色辊离线)。由于线圈单位厚度层数减少,线圈比强度低于正常状态,水平线圈在自身重力作用下发生坍塌。松卷主要是指钢带之间的相对滑动,即钢带之间没有足够的静摩擦力,也就是说钢带之间较大的静摩擦力不足以阻止钢带的相对运动。
山东彩涂卷 在实际生产中,冷轧、热轧卷取过程中经常出现卷边塌陷现象。解决方法通常是纠正张力。设定值一般在普通钢材的基础上增加一定的张力,以增加层间摩擦力。对于不同的聚酯彩涂板,其较大的静摩擦力与环境温度、湿度以及摩擦表面的微观状态有关,尤其是后者。涂层固化后,涂层之间的接触方式为表面接触,涂层不会产生压缩变形。适当增大卷取张力,增加层间静摩擦力,可有效防止塌辊现象的发生。

In the production process, it is inevitable that there will be problems, many manufacturers in the production of color coated coil plate collapse phenomenon, which is a headache at the beginning, so what are the reasons for the phenomenon of color coated coiled plate manufacturers in the production engineering?

Color coated roll
The direct cause of the collapse phenomenon is that the color plate curls and unwinds (the color roll is off-line). Because of the reduction of the number of layers per unit thickness of the coil, the specific strength of the coil is lower than that of the normal state, and the horizontal coil collapses under its own gravity. Loose coil mainly refers to the relative slip between the steel strips, that is, there is not enough static friction between the steel strips, that is to say, the large static friction force between the steel strips is not enough to prevent the relative movement of the steel strips.
In practice, the phenomenon of coil collapse often occurs in the coiling of cold-rolled and hot-rolled coils. The solution is usually to correct the tension. The set value generally increases a certain tension on the basis of ordinary steel, so as to increase the friction between layers. For different polyester color coated boards, the large static friction force is related to the environment temperature, humidity and the micro state of the friction surfaces, especially the latter. After the coating is cured, the contact mode between the coatings is surface to surface contact, and the coating will not produce compression deformation. Properly increasing the coiling tension and increasing the static friction force between layers can effectively prevent collapse Roll phenomenon occurs.
