我们所看到的彩钢瓦的变形主要是由于彩钢瓦中含有的水分使其抗压能力下降,所以会出现变形情况。因此,彩钢瓦的干燥处理是制造工程中的一个关键工序,常用的干燥处理和研磨方法有哪些。

常用的干燥方法是用自建的土窑对彩钢瓦原料进行干燥,以降低产品的干燥成本。由于土窑采用人工烧炕的方法加热,温度不均匀,往往有些土窑已经干燥,有些土窑还有大量的水,无法控制土窑的开裂和变形。
因此,除第一次蒸汽干燥外,第二次微波干燥应在加工前进行,使水分从内向外均匀蒸腾。彩钢瓦施工时,必须对彩钢瓦进行打磨。其用意是坚持其美观,确保施工安全。有三种研磨方法:干研磨、湿研磨和机械研磨。
为了提高工作效率,可以选择机械磨削方法,如电动磨床、圆盘式和摆动式。干磨选用砂纸,适用于硬脆油漆的磨削。这种研磨方式的缺点是在操作过程中会产生大量的粉尘,影响环境健康。
湿磨使用砂纸蘸水或肥皂水抛光彩钢瓷砖。水磨可减少磨痕,提高涂层的平整度,节省砂纸和人力。但是,在水磨后喷涂底漆时,首先要待水磨层完全干燥后才能施涂底漆,否则漆层很简单且呈白色,其他吸水性强的基材不适合水磨。

The deformation of the color steel tile we have seen is mainly due to the moisture contained in the color steel tile which makes its compressive ability drop, so it will present a deformation condition. Therefore, the drying treatment of the color steel tile is a crucial process in the manufacturing engineering, so what are the commonly used drying treatment and grinding methods.

The commonly used drying method is to dry the raw materials of color steel tile with the earth kiln built by ourselves, so as to reduce the cost of drying products. Because the earth kiln is heated by the method of artificial Kang burning, the temperature is not uniform, and often some of them have been dried, and some of them still have a lot of water, and there is no chance to control the cracking and deformation.
Therefore, in addition to the first steam drying, the second microwave drying should be carried out before processing, so that the water can be evenly transpiration from the inside out. During the construction of color steel tile, it is necessary to polish the color steel tile. The intention is to adhere to its beauty and ensure the safety of construction. There are three methods of grinding: dry grinding, wet grinding and mechanical grinding.
In order to improve the working efficiency, mechanical grinding methods can be selected, such as electric grinder, disc type and oscillating type. Sand paper is selected for dry grinding, which is suitable for grinding hard and brittle paint. The defect of this kind of grinding is that there will be a lot of dust in the operation process, which will affect the environmental health.
Wet grinding uses abrasive paper dipped in water or soapy water to polish color steel tiles. Water grinding can reduce grinding marks, improve the smoothness of coating, and save abrasive paper and labor. However, when spraying base paint after water grinding, first, the base paint can only be applied after the water grinding layer is completely dry, otherwise the paint layer is very simple and white, and other base materials with strong water absorption are not suitable for water grinding.
