TPU heat cutting machine sales.There are techniques for maintaining the embossing roller, and you should also know

　　To ensure the surface pattern of the embossing roller, it is usually necessary to perform cleaning treatment on the embossing roller, such as acid pickling to remove rust, using organic substances to remove oil stains, etc., to ensure that its surface is clean and free of dirt. Mechanical sandblasting is usually one of the effective methods to improve its effectiveness. By sandblasting treatment, the surface roughness of the embossing roller is increased, which can increase the surface area of the bonding interface by several times or even dozens of times, thereby improving the bonding force between the surface pattern and the embossing roller. The unevenness of the ground surface caused by sandblasting treatment can improve the bonding strength of the embossing roller surface.

　　Another thing is to keep the embossing roller dry to prevent rusting again. Especially in summer, the moisture in the air can form a layer of water film on the surface of the treated roller, causing rust on the embossing roller. The maintenance of the embossing roller is also important, especially for the surface patterns. It is important to clean them in a timely manner to prevent dirt from blocking the patterns. When cleaning, it is important to use specific tools and not use brute force. Be careful to clean according to the direction of the patterns.
