TPU solding machine Production.Tips for maintaining embossing rollers

　　To ensure the surface pattern of the embossing roller, it is usually necessary to perform cleaning treatment on the embossing roller, such as using 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. The surface roughness of the embossing roller has been increased through sandblasting treatment, which can increase the surface area of the bonding interface by several times or even dozens of times, correspondingly improving the adhesion between the surface pattern and the embossing roller. The uneven surface caused by sandblasting treatment can improve the bonding strength of the embossing roller surface.

　　Also, the embossing roller should be kept dry to prevent rusting again. Especially in summer, the water in the air can form a layer of water film on the treated roller surface, 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, not use brute force, and carefully follow the direction of the patterns.
