How to correctly choose polyurethane rubber rollers is divided into six points:

1. Excellent high temperature resistance, the highest operating temperature can reach more than 250 degrees, 2. High wear resistance, can withstand the pattern of deep-grained rollers without wear, more wear-resistant than polyurethane PU rubber rollers, 3. Better thermal conductivity. 4. Good release and anti-stick properties, can be used for high-viscosity plastics. 5. Good antistatic properties, can produce ultra-thin plastic films without sticking to rollers. 6. The matteness of the sanded rubber roller is uniform.

As for the self-help troubleshooting on the magnetic vibration grinder, first of all, the vibration of the machine will be relatively large. Then, we must pay attention to check whether there is a force position at each corner of the machine. Then, we must pay attention to directly adjust its own length.

The storage room of the polyurethane rubber roller should avoid strong light and radiation, and avoid storage with acids, alkalis, oils and sharp and hard substances. Printing rubber rollers should be stored in a cool, dry, ventilated place in a vertical or horizontal state (temperature 20℃～25℃, relative humidity 60%～70%). When storing rubber rollers horizontally, the rubber head should be placed on the frame to support the shaft shoulders on both sides, and the rubber roller should be kept parallel to the ground. It is strictly forbidden to stack or squeeze the rubber surfaces to prevent the rubber surfaces from being deformed or stuck under pressure. If the rubber rollers are stored for too long, they will naturally age, wrinkle, and the shaft head will rust. Therefore, according to the actual production situation,
