彩涂铝卷是指的经过辊涂设备将各种颜色的油漆涂层到铝卷表面，形成各种颜色的铝卷，颜色多样，色泽美观，使用寿命比彩钢板长，质量轻，强度高，而且防锈耐腐能力强，起到装饰和保护作用，在建筑装饰方面能较好的替代彩钢板。彩涂铝卷制作工艺比较简单，不过清洗步骤常常被厂家忽视，导致制作出来的彩涂铝卷色泽暗沉，而且质量差。那为什么彩涂铝卷制作中需要清洗呢？
Color-coated aluminum coil refers to the roll-coated e be a variety of colors of paint coated to the surface ofaluminum coil, forming a variety of colors of aluminum coil, colorand lustre, service life longer than color steel plate, lightweight, high strength, and corrosion resistance, play a decorativeand protective role in architectural decoration can better replaceColor plate. The color coated aluminum roll is easy to make, butthe cleaning steps are often neglected by manufacturers, resultingin dark color and poor of the color coated aluminum roll.Then why do we need to clean the painted aluminum coil?
彩涂铝板在冷轧制过程中，因轧辊与铝板表面摩擦和碾压，表面会产生细微的氧化铝粉脱落和吸附，轧制油及其附带悬浮成分会残留在铝板表面，对彩涂铝板的涂装、卷制等成品加工造成不利影响。而目拉弯矫直时，带材在辊上易产生剧烈弯曲变形。因此，如果彩涂铝板表面未经清洗，变形时氧化铝粉脱落，随着油污一起附在张力辊的辊面，使辊面产生磨损，并造成铝板损伤，故必须通过专门的清洗装置进行清洗。
In the cold rolling process of color coated aluminum sheet,because of the friction and rolling between the roll and thesurface of the aluminum sheet, fine aluminum oxide powder will falloff and adsorb on the surface, and the rolling oil and itsassociated suspension components will remain on the surface of thealuminum sheet, which will have adverse effects on the coating androlling of the color coated aluminum sheet. In the course ofstraightening, the bending of the strip on the roller is easy.Therefore, if the surface of the color coated aluminum plate is notcleaned, the alumina powder will fall off when it is deformed, andthe oil stains will attach to the surface of the tension rolltogether, which will cause wear and tear on the surface of the rolland damage to the aluminum plate. Therefore, it must be cleaned bya special cleaning device.
清洗就是利用压力泵对对彩涂铝板表面进行非接触式喷洗或接触式刷洗，使表面的铝粉油污溶解脱落到清洗介质中，再经挤干辊挤干和高压空气吹扫，甚至高温空气烘干，以获得洁净干燥的铝材，进而保证成品彩涂铝卷表面的洁净美观。
Cleaning is the use of pressure pumps on the surface ofcolor-coated aluminum plate for non-contact spray washing orcontact washing, so that the surface of aluminum powder oildissolved off to the cleaning medium, and then extruded by dryrolls and high-pressure air blowing, or even high-temperature airdrying, in order to obtain clean and dry aluminum, thus ensuringthe finished product color-coated aluminum coil surface.
