Rubber roller for polishing machine

A Rubber Roller can be simply defined as "a roller core of metal or other materials covered with rubber or other elastic substances." Rubber Rollers utilize the following unique properties of rubber and are used in a variety of applications.Plastic Roller
Properties of rubber roller:
1. The coefficient of friction is high.
2. It can quickly return to its original shape after deformation.
3. Resistant to chemicals and protects roller cores and shafts.
4． Prevents scratches and impact marks.
5. Correct for minor changes in mechanical accuracy.
What are the properties of the rubber roller that can be used well:
1. Wettability: Mainly due to the affinity of the rubber roller to ink (the ink roller must have good lipophilic and water-repellent properties so that the ink can spread well on the surface of the ink roller. This is the basic condition for smoothing the ink layer; enhancing water In addition to selecting polymer materials with sexual groups for roller wettability, the rubber roller also needs to increase the specific surface area of the water roller)
2. Restorability: Since the rubber roller runs in the ink (water) device and is subject to periodic rolling, the rubber roller will be affected by three types of deformation: sensitive elasticity, anelasticity and plastic deformation. The rubber roller is required to have corresponding hardness. Down. At the same time, the rubber roller provided can accurately express the surface pressure, and the pressure performance with good elasticity is obvious. Helps to adjust the pressure correctly according to the indentation between the rollers.
3. Properties: good abrasion resistance helps to maintain the capillary pores on the surface of the rubber roller, increases the anti-glazing ability, and maintains the wettability of the rubber roller.Silicone Roller
