The process flow of polyurethane coated wheels processing
The processing of polyurethane coated wheels needs to go through the following process:
1. Cleaning the iron core: The new rubber roller iron core needs to be cleaned of oil on the surface of the iron core with a cleaning agent.
2. The surface of the rubber roller iron core is roughened: the surface of the rubber roller iron core is roughened to increase the bonding area between the surface of the rubber roller iron core and the encapsulation.
3. Sandblasting: The rough-treated rubber roller core is sandblasted. Sandblasting will select different types of sand according to the material of the rubber roller core for sandblasting. Sandblasting is to make the surface of the rubber roller rougher, and the glue and the iron core can be better bonded after encapsulation.
4. Coating: The rubber roller core after the above treatment is coated according to the customer's requirements.
5. Rubber-coated wheel vulcanization: The rubber-coated rubber roller generally needs 10-15 hours of vulcanization time. After vulcanization, the core of the rubber roller and the rubber will be tightly bonded, and the rubber-coated wheel will be formed.
6. Grinding of rubber-coated wheels: Grind according to the size and shape required by customers. When some customers have high requirements on the surface of the rubber roller, they need to use a CNC grinder to polish the rubber roller.
After the above 6 processes, the polyurethane coated wheel is processed.
