涂装是铝板制造中比较重要的工序,涂装质量的优劣,直接影响了铝板的装饰效果.造成铝板涂装优劣的因素主要有四点,下面就让大家铝板厂家来带大家了解一下这方面的内容吧.对这方面感兴趣的朋友一定不能错过.
Coating is an important process in aluminum plate manufacturing. The quality of coating directly affects the decorative effect of aluminum plate. There are four main factors causing the quality of aluminum plate coating. Let's take you to know about this aspect. Friends who are interested in this aspect must not miss it
1.环境。要求涂装室内部清洁干净,做到防尘、防虫和一定的通风性能,保证铝板涂装表面质量不受污染.同时由于气温变化而及时更改工艺条件.
1. Environment. It is required that the interior of painting room should be clean, dust-proof, insect proof and ventilation performance should be ensured, so as to ensure the surface quality of aluminum coating not to be polluted. At the same time, the process conditions should be changed in time due to the change of air temperature


2.原材料。涂料和铝板是涂装过程中最能影响涂装质量的因素,由于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,在选择原材料时,应严格控制.
2. Raw materials. Coating and aluminum plate are the most important factors affecting the coating quality in the coating process. Due to the color difference between batches of coating, insufficient coating fineness and low coating rate, poor coordination between coating and solvent, delamination and so on, the coating effect will be directly affected, resulting in defects. Uneven aluminum coil substrate, uneven film thickness, poor edge flexibility and so on also directly affect the product quality and overall use Therefore, the selection of raw materials should be strictly controlled
3.设备。涂装线要求涂装设备完好,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.
3. Equipment. The coating line requires the coating equipment to be in good condition, the coating equipment shall run smoothly without transverse and longitudinal vibration, and the coating roller shall be ground finely. The transverse runout of all rollers of the coating machine must be controlled within the allowable range, otherwise the coating surface quality will be seriously affected
4.工艺。涂装工艺对涂装的质量关系密切,要求对涂装辊、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产品的色差和性能.
4. Technology. The coating process is closely related to the coating quality. It is required to control the relative linear speed ratio of coating roller, paint lifting roller, metering roller and substrate in a certain range. According to different systems and coating product film thickness, a certain viscosity range should be set for the coating to ensure the smooth progress of coating and promote the improvement of product quality. The curing process of coating and oven control must be controlled according to the requirements It should not be changed arbitrarily, otherwise it will seriously affect the color difference and performance of coating products
