[Foshan Wanqing Materials] What are the common factors that affect the color difference of black color coating board?
影響黑色彩涂板色差的常見因素
Common factors affecting the color difference of the black color coating board
01涂層厚度
01 Coating thickness
涂層厚薄與應(yīng)用環(huán)境息息相關(guān)。底材的顏色、涂料的厚度改變而產(chǎn)生光澤等因素改變，在涂料調(diào)色過(guò)程中必須考慮充分。
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溶劑揮發(fā)速率
02 Solvent volatilization rate
溶劑的揮發(fā)影響涂層的表面光澤和顏料的定向排列，進(jìn)而影響顏色的色相。
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溶劑的親水性
03 The hydrophilic nature of the solvent
在高濕環(huán)境下，如果涉及到溫度劇烈變化，在溶劑揮發(fā)過(guò)程中，涂層表面因溶劑揮發(fā)而出現(xiàn)溫差，導(dǎo)致涂層表面產(chǎn)生薄層水霧，造成涂層發(fā)白而產(chǎn)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涂層的均勻性
04 Uniformity of the coating
不同顏料因調(diào)配使顏色飽和度不同，相同顏色因不同的施工方式、不同的操作習(xí)慣導(dǎo)致同一塊板材表面產(chǎn)生色斑或?qū)е虏煌宀闹g的厚薄差異，從而影響涂層色差。
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.
影響黑色彩涂板光澤的常見因素
Common factors affecting the gloss of the black color coating board
黑色彩涂板質(zhì)量的好壞不僅和原材料基板有很大關(guān)系，生產(chǎn)工藝對(duì)成品質(zhì)量的好壞起著至關(guān)重要的作用，彩涂板的光澤度就受烘烤工藝等因素的影響。
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.
雖然黑色彩涂板的表面光澤度主要取決于涂料本身，但烘烤工藝、涂料的使用粘度、膜厚以及基板的粗糙度也是決定涂層表面光澤的主要因素。
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.
試驗(yàn)結(jié)果表明，PMT與涂層光澤度有負(fù)相關(guān)的關(guān)系，溫度越高，光澤度越低，但烘烤參數(shù)對(duì)產(chǎn)品光澤度的影響程度較輕。
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.
為控制涂料固化過(guò)程中揮發(fā)的溶劑氣體對(duì)環(huán)境造成的危害，將烘烤爐排出的尾氣，引入焚燒爐內(nèi)燃燒，轉(zhuǎn)變?yōu)闊o(wú)害的水和二氧化碳，燃燒釋放出的熱量繼續(xù)利用來(lái)加熱新鮮空氣。
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.
黑色彩涂板的光澤度是考察產(chǎn)品質(zhì)量的重要因素之一，也會(huì)對(duì)產(chǎn)品的外觀造成一定程度的影響，所以在生產(chǎn)過(guò)程中一定要把握好各個(gè)環(huán)節(jié)對(duì)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.
