辊涂铝卷形成缺陷与什么有关?

来源:

1、原材料
1. Raw materials
涂装过程中最能影响涂装质量的因素是涂料和铝卷,因为涂料的批次之间存在色差,涂料细度不够而涂覆率不高,涂料与溶剂配合不佳、分层等等会直接影响涂装效果而产生缺陷’铝卷基材的不平整、膜厚不均匀、边部挠曲度不佳等也直接影响产品质量和整体使用。因此,对于原材料的选购,大家需相当谨慎严格。
The most influential factors in the coating process are coatings and aluminum rolls, because there are chromatic aberration between the batches, the coating fineness is not enough, the coating rate is not high, the compatibility of the coating and solvent, the delamination and so on will directly affect the coating effect and produce the defects' aluminum roll base material unevenness, film thickness uneven, side deflection. Poor and so on also directly affect product quality and overall use. Therefore, we need to be cautious and strict in choosing raw materials.
2、涂装工艺
2. Coating process
涂装工艺流程要严格规范,一旦某一环节出现差错,则会造成铝卷的缺陷。因此,要对涂装辊、提漆辊、计量辊和基材相对线速比率控制在一定的范围内。要根据不同的体系和涂装产品的膜厚,对涂料设定一定的粘度范围,保证涂装顺利进行,促进产品质量的提高。涂料的固化工艺, 烘箱控制必须按要求控制,不得任意变动,否则将严重影响涂装质量。
The coating process must be strictly regulated, and if there is a mistake in one link, it will cause defects in the aluminum coil. Therefore, it is necessary to control the relative speed ratio of coating roller, paint roller, metering roller and substrate in a certain range. According to different systems and film thickness of coating products, set a certain viscosity range for coatings, ensure smooth coating and improve product quality. The curing process of the coating and oven control must be controlled according to the requirements, and it must not be changed arbitrarily, otherwise, the quality of coating will be seriously affected.

3、涂装设备
3. Coating equipment
涂装设备要求运转平稳,不能有横、纵向抖动,涂装辊要求研磨细腻。涂装机所有辊子横向跳动, 必须控制在允许范围内,否则将严重影响涂层表面质量。
The painting equipment requires smooth operation, no horizontal and vertical jitter, and the coating roller requires fine grinding. All rollers of the painting machine must be controlled within the allowable range, otherwise the surface quality of the coating will be seriously affected.
4、环境因素
4, environmental factors
要保持涂装室内部清洁干净,做到防尘、防虫和一定的通风性能,保证涂装表面质量不受污染。
Keep the paint room clean and clean, dust proof, insect proof and certain ventilation performance to ensure that the surface quality of the painting is not polluted.
5、人为因素
5, human factors
如果辊涂铝卷的操编辑经验欠佳,责任心低,则也会造成铝卷形成缺陷。因此,要加强对操编辑的培训和让操编辑掌握涂装技术的原理和要点,提升技术熟练程度和操作的规范性,加强责任性,严格按操作规程进行操作,以保证高质量的涂装产品。
If the operator who rolls the aluminum roll is not well experienced and the sense of responsibility is low, it will also cause the formation defect of the aluminum coil. Therefore, we should strengthen the training of the operator and the principle and key points for the operator to master the painting technology, improve the technical proficiency and the standardization of operation, strengthen the responsibility, and operate strictly according to the operating rules, so as to ensure the high quality of the coating product.
