The polyurethane roll is generally provided by the customer need to roll core plastic bags, the technical personnel of our company according to customer requirements related to the color, size and hardness of rubber processing.
Polyurethane rubber tire processing needs to go through the following process flow:
1, core cleaning customers: if you are new to the iron core roller surface pollution, cleaning agent 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.
2, the surface of cot core is roughened: the surface of cot core is roughened, so as to increase the adhesion area between the core surface of rubber roller and the glue
3, sandblasting: cots core rough treated sand blasting, blasting will be carried out according to the material of the roller core sand sand of different nature. In order to make the roller surface sandblasting is more rough, plastic bags after the glue and adhesive core better.
4, glue: after the above treatment of COTS core, according to the requirements of the customer glue
5, the package rubber wheel vulcanization: rubber covered roller generally need 10-15 hours of vulcanization time, after vulcanization, rubber roller core and package will be closely bonded, wrapped rubber wheel forming
6, grinding wheel package: according to customer requirements of the size and shape of the roller surface grinding, part of the customer requirements is high, needs to be polished to mirror rollers with CNC grinder.
Through the above 6 processes, polyurethane rubber processing. Wuxi jiunai recommended products of polyurethane products Co. Ltd: polyurethane PU round belt type V non-standard pieces of polyurethane rubber belt pattern with polyurethane polyurethane polyurethane cushion with polyurethane polyurethane polyurethane rubber rollers.
