彩钢板是指彩涂钢板，是一种带有有机涂层的钢板，可以说是人们较为熟悉的板材，当然使用时候会发生的质量问题是不可避免的，下面
济南彩钢小编来列举几项，提前了解并预防。
Color steel plate refers to color coated steel plate, which is a kind of steel plate with organic coating. It can be said that it is a familiar plate. Of course, the quality problems that will occur when used are inevitable. The following Jinan color steel editor will list several items to understand and prevent in advance.
弯曲性不良（T弯）
Poor bending (T-bend)
钢材弯曲180度试验时，加工部位的涂层发生龟裂及涂层剥离。
During the 180 degree bending test of steel, the coating on the processing part cracks and peels off.
发生原因： 1、前处理的掌握量过多。2、涂层厚度过厚。3、过度烘烤。4、下涂涂料同上涂涂料的制造厂家不同，或稀料的使用不当。
Causes: 1. Too much pre-treatment. 2. The coating thickness is too thick. 3. Over bake. 4. The lower coating is different from the manufacturer of the coating, or the thinner is improperly used.
边部气泡
Edge bubble
两侧沾有涂料，经烘干，出现气泡。
There is paint on both sides. After drying, bubbles appear.
发生原因：原材有毛刺沾有涂料多，两边出现缝隙。
Cause of occurrence: raw materials have burrs and paint, and cracks appear on both sides.
麻点
Pitting
特点：从外部混入的异物或灰尘在涂装后,部分或全部表面,有米粒样的突出。
Features: foreign matters or dust mixed from the outside will protrude on some or all surfaces after coating.
发生原因：1、涂料中混入其它种类或其它公司的涂料。2、涂料中有异物混入引起。3、前处理过程中水洗不良。
Causes: 1. The paint is mixed with other kinds of paint or paint from other companies. 2. It is caused by the mixing of foreign matters in the paint. 3. Poor washing during pretreatment.
橘皮
Orange peel
特点：已干燥的表面涂层象橘子皮一样粗糙，不均匀。
Features: the dried surface coating is as rough and uneven as orange peel.
发生原因：1、湿膜过厚。2、涂料的黏度较高时。
Causes: 1. The wet film is too thick. 2. When the viscosity of paint is high.
耐溶剂性能差（MEK)
Poor solvent resistance (MEK)
特点：擦拭有点状掉漆。
Features: there are dots of paint falling off after wiping.
发生原因：1、烘烤温度没有达到要求。 2、涂料的固化有问题。3、前处理清洗不干净。
Causes: 1. The baking temperature did not meet the requirements. 2. There is a problem with the curing of the coating. 3. The pretreatment and cleaning are not clean.
缩孔
Shrinkage cavity
特点： 漆膜不平整，局部露底。
Features: the paint film is uneven and partially exposed.
发生原因：1、钢带表面不洁净。2、底漆冷却水不洁净。3、涂料粘度没达到上机要求。
Causes: 1. The steel strip surface is not clean. 2. The cooling water of primer is not clean. 3. The viscosity of the coating did not meet the requirements of the machine.
漏涂
Holiday coating
特点：面漆未涂上。
Features: topcoat is not applied.
发生原因：1、边部面漆未涂上，基板板型不好或涂辊与大背辊间压力不足。2、板面中间面漆未涂上，底漆冷却后板面有水或其它异物。
Causes: 1. The edge finish paint is not applied, the base plate shape is not good, or the pressure between the coating roll and the large back roll is insufficient. 2. The middle finish of the plate surface is not painted, and there is water or other foreign matters on the plate surface after the primer is cooled.
塌卷
Collapse roll
特点：钢卷卷取后在仓库存储时内径变形。
Features: the inner diameter of the steel coil is deformed when it is stored in the warehouse after coiling.
发生原因： 1、钢卷卷取后受外力的影响。2、收卷张力不正确。3、荷重不均。
Causes: 1. The steel coil is affected by external force after coiling. 2. The winding tension is incorrect. 3. Uneven load.
反粘
Anti adhesion
特点：开卷时有轻度剥离，底漆返沾会出现类似小米粒状颗粒，涂面漆后表面凹凸不平。
Features: there is slight peeling when uncoiling, and there will be particles similar to millet particles when the primer is back stained, and the surface will be uneven after coating the top coat.
发生原因：1、卷取前冷却不够。2、烘烤不足。3、部分载重过大。
Causes: 1. Insufficient cooling before coiling. 2. Insufficient baking. 3. Part of the load is too large.
压伤
Crush injury
特点：在涂敷之后的压坑。
Features: pressure pit after coating.
发生原因：1、原料卷有压伤。2、在涂敷之前通过各种辊子压伤。3、在涂敷之后和涂料一块的压伤。
Causes: 1. The raw material roll is crushed. 2. Crush by various rollers before coating. 3. Crushing with paint after coating.
