彩色涂层彩涂板饰面安装要点和注意事项

我们都知道彩色镀锌板的颜色是多种多样的。彩涂镀锌板的颜色问题以及如何控制色差是我国生产厂家需要克服的问题,也是保证产品质量的关键。
不同尺寸的基体锌花会在晶界形成大量的小凹坑,对色差的形成有影响,尤其是对浅色。选择无锌花或小锌花的基质效果较好。
如何控制彩涂镀锌板的色差?我们的生产设备是用天然气来供应烘箱温度的,所以烘箱温度是平衡的,不会有时间差,生产前必须把油漆调整均匀。

膜厚的稳定性对彩涂板的色差有很大的影响。膜厚的调整主要包括:涂布粘度、调整粘辊与涂布辊之间的间隙、改变涂布辊与粘辊的辊速、调整涂布辊与带钢支承辊之间的压力。
对于彩涂镀锌板的控制,漏涂是由于基体、变形、氧化等因素造成的。当然,控制色差是保证产品质量的关键因素,因此必须引起每个经营者的重视,从而更有效地保证产品的可用性。
由于涂料混合不均匀或涂料在不同桶内粘度高,托盘中的涂料从进料口一侧向回料口方向延伸,呈现色差带。另外,改变涂层颜色时,颜色对比度大。由于清洗不干净,污染形成色差。

We all know that the color of color coated galvanized sheet is diverse. The color problem and how to control the color difference of color coated galvanized sheet are the problems that our manufacturers need to overcome, and also the key to ensure the quality of products.

The different size of the substrate zinc flower will form a lot of small pits in the grain boundary, which has an impact on the formation of color ifference, especially for light color. It is better to select the substrate without zinc flower or small zinc flower.
How to control the color difference of color coated galvanized sheet? Our production equipment uses natural gas to supply the oven temperature, so the oven temperature is balanced, there will be no time difference, and the paint must be adjusted evenly before production.
The stability of film thickness has a great influence on the color difference of color coated sheet. The adjustment of film thickness mainly includes: coating viscosity, adjusting the gap between the sticking roll and the coating roll, changing the roll speed of the coating roll and the sticking roll, and adjusting the pressure between the coating roll and the strip backup roll.
As for the control of color coated galvanized sheet, the missing coating is caused by the substrate, deformation, oxidation and other factors. Of course, controlling the color difference is the key factor to ensure the product quality, so we must attract the attention of every operator, so as to more effectively ensure the usability of the product.
Due to the uneven mixing of the coating or the high viscosity of the coating in different barrels, the coating in the tray extends from the side of the feed port to the direction of the return port, showing a color difference band. In addition, when changing the color of the coating, the color contrast is large. Due to the unclean cleaning, the pollution forms the color difference.
