The rubber roller is a roll-shaped product made of metal or other materials as the core and covered with rubber through vulcanization. Rubber rollers are generally composed of outer rubber, hard rubber layer, metal core, roller neck and vent holes. Its processing includes roller core sandblasting, bonding treatment, glue forming, cloth wrapping, iron wire winding, vulcanizing tank vulcanization and surface processing And other processes. Rubber rollers are mainly used in papermaking, printing and dyeing, printing, food processing, metallurgy, plastic processing, etc. The rubber roller utilizes the characteristics of the rubber body and is widely used in various industrial production.
Usually rubber rollers have the following characteristics:
1. Higher friction coefficient;
2. The original shape can be quickly restored after deformation;
3. It has certain compatibility with chemicals and can protect the roller core and shaft;
4. Prevent scratches and impact marks;
5. A small amount of change in mechanical accuracy is corrected;
6. Other special functions.
※ Good dielectric or insulator.
※ The electrical characteristics can be changed to become a conductor or a semiconductor.
※ Using low surface energy to achieve anti-sticking effect (silica gel).
※ Special processing of rubber surface (grooved rollers, spiral processing, etc.).
※ High temperature resistance, etc.
The production of rubber rollers from the above rubber characteristics requires a variety of complex technologies and experience:
1. The rubber material related properties of the rubber roller
The rubber of the same raw material also varies greatly in performance according to the formula and processing technology. This fully reflects the strength of manufacturers.
2. Polishing accuracy
Diameter, length, straightness, roundness, runout, middle height, surface roughness, etc.
3. Quality stability
The uniformity of strength and hardness prevents the occurrence of foreign matter pinholes.
4. Roll core material and structure
Reasonably choose materials for different purposes and corresponding processing plans to avoid products that may cause problems.
5. Bonding strength of roller core and rubber
Insufficient adhesion may cause problems such as rubber falling off the roller core and cracking.
