The deformation of Jinan color steel tile is mainly due to the decrease of its compressive capacity due to the moisture content of the color steel tile. Therefore, the drying treatment of color steel tile is a crucial process in manufacturing engineering. What are the common drying treatment and grinding methods?
Jinan color steel tile
The commonly used drying method is to dry the raw materials of the color steel tile with the soil kiln built by ourselves, so as to reduce the cost of drying the products. Because the earth kiln is heated by using the method of artificial Kang burning, the temperature is not uniform, and some of them are dried, while some of them still have a lot of moisture, and there is no chance of cracking and deformation.
Therefore, in addition to the first steam drying, the second microwave drying should be carried out before processing, so that the moisture can be evenly transpiration from inside to outside. During the construction of color steel tile, Jinan color steel tile needs to be polished. Its intention is to adhere to its beauty and ensure the safety of construction. There are three grinding methods: dry grinding, wet grinding and mechanical grinding.
In order to improve the work efficiency, mechanical grinding method can be used in large area construction of mechanical grinding color steel tile, such as electric grinding machine, disc type and oscillating type. Sand paper is used for dry grinding, which is suitable for grinding hard and brittle paint. The defect of this kind of grinding for color steel tile is that a lot of dust will occur in the operation process, which will affect the environmental health.
Wet grinding uses sandpaper dipped in water or soapy water to polish color steel tile. Water grinding can reduce grinding marks, improve the smoothness of coating, and save sandpaper and labor. However, when spraying base paint after water grinding, one should wait until the water grinding layer is dry, otherwise the paint layer is very simple and white, and other base materials with strong water absorption are not suitable for water grinding.
The above is the Jinan color steel tile drying and grinding methods, I hope this article can help you. In addition, we must pay special attention to drying and grinding, to avoid causing some unnecessary trouble!
