讲述彩涂铝板表面滚涂工艺

彩涂铝板表面除油、化学处理后,在彩涂铝板表面涂上优质涂料,干燥固化。辊涂板表面漆膜的平整度高于喷涂板。颜色分为珠光和哑光,市面上常见的是珠光。它的价格比喷雾的价格高。滚涂板大的特点是颜色模拟度很高,滚涂工艺质量差别很大。除了所有的材料,也有一些事情在几次。比如两道漆两卷,也就是说,喷一次就是烤一次,再喷再烤,这样颜色就更均匀、更光滑了。好的滚涂板价格也很贵,颜色逼真耐用。

彩涂铝板进口氟碳辊涂也是滚涂的一种,即在颜料中加入氟碳,使颜色附着力更强,使用寿命更长,耐酸碱、耐腐蚀。它常用于建筑物的外装饰(不怕风雨),价格高,成本高,是目前世界上档次高的滚涂板之一。
滚涂板表面处理工艺如下:
辊涂板上有面漆、底漆和背漆。背涂层主要起到抗氧化作用,使用寿命更长。半成品-机械-成型-卸货和检验-包装和仓储。
滚涂板表面均匀光滑,无漏涂、缩孔、划伤、脱落等明显缺陷。但表面存在一些微缺陷,如气泡、凹坑、夹杂物等,属于正常现象。


After degreasing and chemical treatment on the surface of aluminum plate, high-quality coating is applied on the surface of aluminum plate, which is dried and solidified. The flatness of the paint film on the surface of the roller coating plate is higher than that of the spray coating board. The color is divided into pearlescent and matte, the most common on the market is pearlescent. Its price is higher than that of spraying. The biggest feature of roll coating board is that the color simulation degree is very high; the quality of roll coating process is very different. Besides all materials, there is also something to do with it in several times. For example, two coats and two rolls, that is, spraying once is baking once, and then spraying and baking again, so that the color is more uniform and smooth. The price of good roll coating board is also very expensive, the color is lifelike and durable.

Imported fluorocarbon roller coating is also a kind of roll coating, that is, adding fluorocarbon in the pigment makes the color adhesion stronger, the service life longer, the acid and alkali resistance and the corrosion resistance. It is often used in the external decoration of buildings (not afraid of wind and rain), with high price and cost, and it is one of the highest grades of roll coating board.
The surface treatment process of roll coating plate is as follows:
There are top coat, primer and back paint on the roller coated plate. The back coating mainly plays an anti-oxidation effect and makes its service life longer. Semi finished products - machine - forming - unloading and inspection - packaging and warehousing.
The surface of the roll coating plate is uniform and smooth, without obvious defects such as missing coating, shrinkage cavity, scratch and falling off. However, there are some micro defects on the surface, such as bubbles, pits and inclusions, which are normal phenomena.
