The moisture contained in the color steel tile will reduce its compressive capacity, and the result is the deformation we see. Therefore, the drying treatment of the color steel tile is a very important step in the manufacturing project. What are the common drying treatment and grinding methods:

常用的烘干方法是用自己建的土窑对彩钢瓦的原材料进行烘干处理，减少对于成品烘干的成本。

The common drying method is to use the earth kiln built by ourselves to dry the raw materials of color steel tiles, so as to reduce the drying cost of finished products.

因为土窑是采用人工烧炕的方式加热，温度不均匀，经常会出现一部分已经烤干了，而有的还存在许多水分，也没有控制好开裂和变形的几率。所以除了要进行一次的蒸汽烘干以外，在加工之前还要进行二次的微波烘干，是的水分可以从里往外均衡蒸发。

Because the earth kiln is heated by manually burning Kang, the temperature is uneven, and often some have been dried, while some still have a lot of moisture, and the probability of cracking and deformation is not well controlled. Therefore, in addition to the primary steam drying, the secondary microwave drying should be carried out before processing. Yes, the water can evaporate evenly from inside to outside.

彩钢瓦在施工的时候，需要对彩钢瓦进行打磨，其目的是保持它的美观性，保证施工的安 全性。对于它的打磨方式分为干打磨、湿打磨和机械打磨三种：

During the construction of color steel tile, it is necessary to polish the color steel tile in order to maintain its beauty and ensure the safety of construction. Its grinding methods are divided into dry grinding, wet grinding and mechanical grinding:

1、机械打磨

1. Mechanical grinding

彩钢瓦大面积施工时，为了提高工作效率，可采用机械打磨方法，如电动打磨机，有圆盘式和振动式。

During large-area construction of colored steel tiles, in order to improve work efficiency, mechanical grinding methods can be adopted, such as electric grinder, including disc type and vibration type.

2、干打磨

2. Dry grinding

采用砂纸进行打磨，适用于硬而脆的漆种的打磨，这种对彩钢瓦进行打磨的缺点是操作过程中将产生很多粉尘，影响环境卫生。

Sandpaper is used for grinding, which is applicable to the grinding of hard and brittle paint. The disadvantage of this kind of grinding of color steel tile is that a lot of dust will be generated during operation, affecting environmental sanitation.

3、湿打磨

3. Wet grinding

用水砂纸蘸水或肥皂水打磨彩钢瓦，水磨能减少磨痕，提高涂层的平滑度，并且省砂纸、省力，但水磨后应注意喷涂下层油漆时，一是要等水磨层完全干透后才能涂下层油漆，否则漆层很容易泛白，另外吸水性很强的底材也不宜水磨。

Polish the colored steel tile with sand paper dipped in water or soapy water. Water grinding can reduce grinding marks, improve the smoothness of the coating, and save sand paper and labor. However, when spraying the lower layer of paint after water grinding, first, the lower layer of paint can be painted only after the water grinding layer is completely dry, otherwise the paint layer is easy to whiten, and the substrate with strong water absorption is not suitable for water grinding.
