Generally, the printing rubber rollers usually appear, wear, and holes in the work project. If the new roller is replaced, the cost is too high and the production progress is affected. Rubber repairing agent can be used for repair. Repairing process, take BD916 rubber repairing agent produced by DECAI factory as an example:
1. Surface treatment: Clean, decontaminate, degrease, and dry the touch hair to be repaired.
2. For repairing with glue, pour the rubber repair agent curing agent B group into the iron can of the main agent group A, quickly stir evenly (A:B=1:1), and then pour it to the place to be repaired and smooth it
3. Curing: It can be used for 4-6 hours after curing at room temperature, and the maximum strength is reached within 48 hours.
Classification of rubber rolls
According to the purpose, it can be divided into: papermaking rubber roller, printing and dyeing rubber roller, printing rubber roller, grain hulling rubber roller, metallurgical rubber roller and mimeograph rubber roller, etc.;
According to the surface morphology, it can be divided into: flat roller and patterned rubber roller;
According to the material, it can be divided into: butyl rubber roller, nitrile rubber roller, polyurethane rubber roller and silicone rubber rubber roller, etc.
The rubber roller is generally composed of outer rubber, hard rubber layer, metal core, roll neck and ventilation holes. Its processing includes roll core sandblasting, bonding treatment, glue forming, cloth wrapping, wire winding, vulcanization tank vulcanization and surface processing. and other processes.
Rubber rollers are mainly used in papermaking, printing and dyeing, printing, food processing, metallurgy, plastic processing and so on.
Natural rubber roller Excellent elasticity and mechanical strength, good alkali resistance, used in textile, paper, leather, packaging and other equipment pressing type rubber roller and metallurgy, mining and other industries traction type rubber roller.
Nitrile rubber roller has excellent oil resistance, and good wear resistance, aging resistance and heat resistance. It is used in printing, printing and dyeing, chemical fiber, papermaking, packaging, plastic processing and other equipment and other occasions that contact oil and aliphatic hydrocarbon solvents .
Neoprene rubber roller has excellent abrasion resistance, high fire resistance, aging resistance, good heat resistance, oil resistance and acid and alkali resistance, used in printed board corrosion machines, plastics, leather, printing, food printing, general Coating machines and other equipment.
