    Now traditional hot encapsulation is difficult to meet the needs of the industry, so the roller polyurethane encapsulation cold encapsulation process came into being, which has the advantages of convenient on-site construction, high bonding strength, fast curing speed and long service life. Polyurethane rubber-coated wheels and rollers are generally provided by customers with roller cores that need to be rubberized or provide drawings and corresponding requirements. Our company's technical personnel are based on the color, size and hardness of the customer's requirements and the relevant requirements of the working environment. Select the corresponding formula for encapsulation processing.
    In the cold treatment of polyurethane encapsulation, the rubber on the surface of the drum should be shoveled off first, and the surface should be polished with an angle grinder. A grinding wheel or fiber polishing disc can be used for polishing.
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.
The rough-treated rubber roller core is sandblasted, and the 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.
