What are the processes needed for rubber roll wrap processing?
The cleaning roller core: if the new rollers need to iron core surface pollution, cleaning agent for cleaning; if the old roller core, the outer rollers need to old plastic bag removal, and cleaning agent for the surface of the iron core residual glue clean.
Plastic bags: after the treatment of roller core customers according to the requirements of plastic bags, plastic bags of different materials to different requirements, such as: Rubber resistant ink performance, wear resistant performance package polyurethane adhesive, silica gel bag good temperature resistance.
Sand blasting: the rough treated roller core shall be sand blasted, and sand blasting will be carried out according to the material of the roller core to select sand of different properties. Sand blasting is to make the surface of rubber roller more rough, and the glue is better bonded with the core.
Rough surface treatment of the core of industrial Cots: roughening the surface of the roller core to increase the adhesion area between the core surface of the roller and the glue.
Top roller vulcanization: the rubber covered roller usually needs 10-15 hours of vulcanization time. After vulcanization, the rubber roller core and the bag glue are tightly bonded, and a rubber covered roller is formed.
