铝板表面经脱脂、化学处理后，滚涂优质涂料，干燥固化。辊涂板表面漆膜的平整度应高于喷涂板的平整度。颜色分为珠光和哑光，珠光在市场上很常见。它的价格比喷雾的价格高。辊涂板最大的特点是色彩模拟度高；辊涂工艺的质量和等级差别很大。除了所有的材料外，它还与它的多次着色有关。例如，两道涂层和两道轧制，喷涂一次，烘烤一次，然后再喷涂和烘烤。这样，颜色更均匀、更平滑。一个好的辊涂板也是非常昂贵，现实和耐用。

进口氟碳辊涂也是一种辊涂，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。通常用于建筑物的外部装饰（不怕风雨）。价格和成本都很高。它是辊涂板的最高等级。
辊涂板的表面处理工艺如下：
辊涂板有面漆、底漆和背漆。背漆主要起到抗氧化作用，使其使用寿命更长。半成品。上部机器。成型。下部和检验。包装和仓储。
滚涂板表面应均匀光滑，无明显漏涂、缩孔、划伤、脱落等缺陷。然而，表面存在气泡、凹坑和夹杂物等微缺陷，这是正常现象。

After degreasing and chemical treatment on the surface of aluminum plate, roll coating high-quality coating, drying and curing. The flatness of the paint film on the surface of the roller coated plate shall be higher than that of the sprayed plate. The color is divided into pearlescent and matte, and pearlescent is common in the market. Its price is higher than that of spraying. The biggest feature of roller coating board is the high degree of color simulation; The quality and grade of roller coating process vary greatly. In addition to all materials, it is also related to its coloring several times. For example, two coating and two rolling, spraying once, baking once, and then spraying and baking again. In this way, the color is more uniform and smooth. A good roller coating board is also very expensive, realistic and durable.

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