[Foshan Wanqing Materials] What are the common factors that affect the color difference of black color coating board?
影响黑色彩涂板色差的常见因素
Common factors affecting the color difference of the black color coating board
01涂层厚度
01 Coating thickness
涂层厚薄与应用环境息息相关。底材的颜色、涂料的厚度改变而产生光泽等因素改变,在涂料调色过程中必须考虑充分。
The coating thickness is closely related to the application environment.The color of substrate, the thickness of coating and other factors change, must be fully considered in the process of coating color adjustment.
02溶剂挥发速率
02 Solvent volatilization rate
溶剂的挥发影响涂层的表面光泽和颜料的定向排列,进而影响颜色的色相。
The volatilization of the solvent affects the surface luster of the coating and the directional arrangement of the pigment, thus affecting the color phase.
03溶剂的亲水性
03 The hydrophilic nature of the solvent
在高湿环境下,如果涉及到温度剧烈变化,在溶剂挥发过程中,涂层表面因溶剂挥发而出现温差,导致涂层表面产生薄层水雾,造成涂层发白而产生色差。
In the high humidity environment, if a drastic temperature change is involved, in the process of solvent volatilization, the coating surface appears in temperature difference due to solvent volatilization, resulting in a thin layer of water mist on the coating surface, resulting in white coating and color difference.
04涂层的均匀性
04 Uniformity of the coating
不同颜料因调配使颜色饱和度不同,相同颜色因不同的施工方式、不同的操作习惯导致同一块板材表面产生色斑或导致不同板材之间的厚薄差异,从而影响涂层色差。
Different pigments have different color saturation due to the deployment, and the same color is due to different construction methods, different operation habits
The surface of the same plate produces color spots or causes the thickness difference between different plates, which affects the color difference of the coating.
影响黑色彩涂板光泽的常见因素
Common factors affecting the gloss of the black color coating board
黑色彩涂板质量的好坏不仅和原材料基板有很大关系,生产工艺对成品质量的好坏起着至关重要的作用,彩涂板的光泽度就受烘烤工艺等因素的影响。
The quality of black color coating board is not only related to the raw material substrate, the production process plays a vital role in the quality of finished products, the gloss of color coating board is affected by the baking process and other factors.
虽然黑色彩涂板的表面光泽度主要取决于涂料本身,但烘烤工艺、涂料的使用粘度、膜厚以及基板的粗糙度也是决定涂层表面光泽的主要因素。
Although the surface gloss of the black color coating board mainly depends on the coating itself, the baking process, the viscosity of the coating, the film thickness and the roughness of the substrate are also the main factors that determine the burnish of the coating surface.
试验结果表明,PMT与涂层光泽度有负相关的关系,温度越高,光泽度越低,但烘烤参数对产品光泽度的影响程度较轻。
The test results show that the PMT and the coating gloss have a negative correlation, the higher the temperature, the lower the gloss, but the baking parameters have less influence on the product gloss.
为控制涂料固化过程中挥发的溶剂气体对环境造成的危害,将烘烤炉排出的尾气,引入焚烧炉内燃烧,转变为无害的水和二氧化碳,燃烧释放出的热量继续利用来加热新鲜空气。
In order to control the environmental harm caused by the volatile solvent gas in the curing process of coating curing, the exhaust gas from the baking oven is introduced into the incinerator for combustion and transformed into harmless water and carbon dioxide. The heat released by the combustion continues to be used to heat the fresh air.
黑色彩涂板的光泽度是考察产品质量的重要因素之一,也会对产品的外观造成一定程度的影响,所以在生产过程中一定要把握好各个环节对它的控制。
The gloss of black color coating board is one of the important factors to investigate the quality of products, and will also cause a certain degree of impact on the appearance of the product, so we must grasp the control of each link in the production process.
