Due to different varieties of sanding belts, the changes caused by climate and environment are also different. Generally speaking, the warehouse where the abrasive belt is stored should be Shady, dry and ventilated. The sanding belt should be placed neatly on the cargo rack, and cannot be placed on the ground. The cargo rack should be kept at a distance of one meter from the ground and walls. while avoiding being close to the heat radiation and drainage devices.
The ideal temperature for belt storage is 18 ~ 22 degrees, and the humidity is 55%-65%. It is not good to open the package before using the abrasive belt.
Especially the requirements for storage conditions for polyester-cotton belts and paper belts are more strictly. They will become deformed and turn perishing at high temperatures and low humidity. Polyester cloth belts are more sensitive to cold and cannot be stored in cold warehouses.
As far as abrasive belts are concerned, ideal storage is important. But if they cannot be properly handled before use, it will still seriously affect its performance.
Before use, the belt should be suspended. The unpacked belt should be hung on a tube with a diameter of 100 ~ 250mm. Let it hang for 2 or 3 days. The principle of selecting the diameter of the tube is to choose a pipe with a large diameter for coarse particle belts(grit number is small, the grinding particle is more coarse). And a pipe with a smaller diameter fine particle belts(grit number is large, the grinding particle is fine)
The purpose of the belt suspension is to eliminate the curl caused by the packaging. And also let the belts adapt to the temperature and humidity of the working environment. When the abrasive belt is suspended, the joint should be on the pipe, and the pipe should be in a horizontal status.
Polyester belts must have sufficient warming time before use. The hanged belts shall be subjected to the necessary quality inspection before use, to check whether the joint of the sanding belt is firm, whether there are holes in the surface, whether the edges are neat and cracked, and if there are small cracks on the edges, it will not be affected after being cut into circular arc shape.
When using the belt, make sure that its running direction is the same as the direction marked on the back of the belt. Avoid the break of belts during operation or affect the surface quality of the workpiece surface. The belt should be unloading turned for a few minutes before grinding. And the grinding should start when the belt is running normally.
