贴可剥离保护膜的彩涂板有什么特点

在冷弯成形后处理中，具有可剥离保护膜的彩涂板不会出现弯辊挤压掉漆现象。所形成的保护膜的结合强度取决于温度，应在20～25℃下剥离。在剥离保护膜的过程中，应注意，由于周围空气干燥程度的影响，可能会产生轻微的静电。当彩涂板保护膜长时间粘附时，

不会剥落或变色，特别是在阳光直射或紫外线照射下，或环境温度为40℃时。剥离保护膜后，表面光泽度偶尔会略有增加，但随着时间的延长或稍微加热，这种现象就会消失。彩涂板在堆码、装载、贮存过程中，如果在生长期施加压力，剥离后保护膜的颜色会发生变化或彩涂板表面光泽度不均匀，

In the post-processing of cold bending forming, the color coated sheet with strippable protective film will not have the phenomenon of paint dropping from the extrusion of bending roll. The bonding strength of the formed protective film depends on the temperature, and should be peeled at 20 ~ 25 ℃. In the stripping process of the protective film, it should be noted that slight static electricity may be generated due to the influence of the drying degree of the surrounding air. When the protective film adheres for a long time, it may not peel off or change color, especially when exposed to direct sunlight or ultraviolet light, or when the ambient temperature is 40 ℃. After stripping the protective film, the surface gloss will increase slightly occasionally, but this phenomenon will disappear with the extension of time or a little heating. In the process of stacking, loading and storage of color coated boards, if the pressure is applied during the growth time, the color of the protective film may change or the surface gloss of color coated boards may be uneven after stripping,
