Various technical indicators are different from ordinary rubber crawlers. Not all manufacturers can produce qualified rubber blasting machines for shot blasting machines. Consumers must learn to identify them. The main points are as follows:
1. Look at the colloid. The rubber track of the shot blasting machine consists of three layers. The outermost part is covered with glue. It is directly in contact with the workpiece to be cleaned, and it is hit by the steel shot, so the wear is severe and it bears great destructive power. The life of the top cover rubber is almost the life of the shot blasting machine track. The glue is also exposed to the outermost rubber, and the quality can be seen and touched.
2, touch by hand, good rubber is elastic, rubber is made by the mold, in order to let the gas in the cavity discharge, the mold has exhaust pores, will leave the exhaust line on the rubber, with the hand Pull the exhaust line and feel the elastic foot, then the rubber is good;
3. The spot on the surface of the shot blasting machine's track is the rubber stain that has been applied to the mold for a long time without affecting the quality.
