铝板卷材涂装质量要怎么看?

1.原材料
1. Raw materials
涂层和铝卷是涂层过程中最重要的影响因素。由于涂料批次之间的色差,铝板涂料细度不够,涂装率不高。涂层与溶剂匹配不好,脱层等都会直接影响涂层效果,产生缺陷。铝线圈基板的不平整、膜厚不均匀、边缘偏转不良也直接影响产品的质量和整体使用。因此,原材料的选择要严格控制。
Coating and aluminum coil are the most important factors in the coating process. Due to the color difference between coating batches, the fineness of aluminum plate coating is not enough, and the coating rate is not high. Poor matching between coating and solvent and delamination will directly affect the coating effect and produce defects. The unevenness of aluminum coil substrate, uneven film thickness and poor edge deflection also directly affect the quality and overall use of products. Therefore, the selection of raw materials should be strictly controlled.
2.装备
2. Equipment
涂装线要求涂装设备状态良好,涂装设备运转平稳,不得有水平和垂直晃动,涂装辊要磨细。涂布机各辊的横向跳动必须控制在允许范围内,否则会严重影响涂层表面质量。
The coating line requires the coating equipment to be in good condition, the coating equipment to operate stably without horizontal and vertical shaking, and the coating roller to be ground. The lateral runout of each roll of the coater must be controlled within the allowable range, otherwise the coating surface quality will be seriously affected.

3.过程
3. Process
铝板涂布过程与涂布质量密切相关,要求涂布辊、提漆辊、计量辊和基材的相对线速度比控制在一定范围内。根据涂层产品的不同体系和膜厚,应为涂层设定一定的粘度范围,以保证涂层的光滑,促进涂层产品质量的提高。涂料的固化过程和烘箱控制必须按要求控制,不允许任意改变,否则会严重影响涂料产品的色差和性能。
The coating process of aluminum plate is closely related to the coating quality. The relative linear speed ratio of coating roller, paint lifting roller, metering roller and substrate is required to be controlled within a certain range. According to different systems and film thickness of coating products, a certain viscosity range should be set for the coating to ensure the smoothness of the coating and improve the quality of coating products. The curing process and oven control of the coating must be controlled according to the requirements, and no arbitrary change is allowed, otherwise the color difference and performance of the coating products will be seriously affected.
4.环境
4. Environment
要求喷漆室内部清洁、防尘、防虫、通风,确保喷漆表面质量不受污染。同时,由于气温的变化,工艺条件也及时发生变化。
The interior of the paint booth shall be clean, dustproof, insect proof and ventilated to ensure that the painted surface quality is not polluted. At the same time, due to the change of temperature, the process conditions also change in time.
5.人性因素
5. Human factors
铝板操作员的责任、技术熟练程度和操作的标准化是获得高质量涂层效果的关键。因此,要更加重视操作人员培训,让操作人员掌握涂装工艺的原理和要点,强化责任,严格按照操作规程操作,确保高质量涂装产品。
The responsibility, technical proficiency and operation standardization of aluminum plate operators are the key to obtain high-quality coating effect. Therefore, more attention should be paid to the training of operators, so that operators can master the principles and key points of coating process, strengthen responsibility, operate in strict accordance with operating procedures, and ensure high-quality coating products.
