Polyurethane is a polymer containing urethane groups in the main chain of the macromolecule. It is usually divided into two categories: polyester polyurethane and polyether polyurethane. The material is very soft and can be used to make many types of industrial products. Polyurethane roller encapsulation is one of the more widely used products. Let's learn about the processing flow of polyurethane encapsulation.
1. Cleaning the iron core provided by the customer: If it is a new rubber roller iron core, the oil on the surface of the iron core should be cleaned with a cleaning agent; if it is an old rubber roller iron core, the outer coating of the old rubber roller needs to be removed At the same time, clean the remaining glue 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 for sandblasting according to the material of the rubber roller core. 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 roller 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 mirror surface.
