The performance of the polyurethane rubber wheel has a huge impact on the whole machine, and it is extremely strict on the process operation and production quality. Many of its products have been classified as fine products. The selection of rubber and plastic materials and the control of product dimensional accuracy are the key. Utilizing its high temperature resistance, ozone resistance, chemical inertness and non-adhesion to plastics, it is used to process hot-bonded products, such as polyethylene calendering, embossing, printing and dyeing, film and fabric coating adhesives, plastic composites, corona Processing machinery is also used as a release roller on sugar production and packaging machines and non-woven fabric manufacturing.
At present, there are various methods of grinding polyurethane rubber wheels, but mainly mechanical turning and polishing. For this reason, the grinding method, grinding tools and abrasives used are very important, and enterprises often regard them as technical know-how and maintain an unannounced attitude. The biggest problem is how to solve the heat generation of rubber during grinding and maintain the best deflection of the surface after grinding.
Polyurethane rubber wheel molding is mainly to paste coated rubber on the metal core, including wrapping method, extrusion method, molding method, injection pressure method and injection method. At present, the main domestic use is mechanical or manual paste molding, and most foreign countries have achieved mechanical automation.
