Polyurethane rubber roller is composed of a metal core, an adhesive layer and an outer polyurethane rubber layer, wherein the inner metal core is a very important factor related to the safety of its use. In the process of making the polyurethane rubber roller, Improve the quality of the corresponding metal core of the technical requirements are as follows:
1, metal roller core material available cast iron or steel, steel and other metal materials, metal wall thickness of different materials to meet the requirements and security requirements.
2, polyurethane rubber roller metal core as a hollow cylinder, wall thickness should be uniform.
3, the size of the structure with the overall size of polyurethane rubber roller meet, and the surface processing to comply with the provisions of the agreement with the production and use.
4, the surface shall not have trachoma, porosity and other defects.
5, both ends of the shaft must have a center hole.
In the paper, steel, printing and dyeing, textile and other industries use polyurethane roller strength is different, so we for the internal quality of the metal core to make a certain design, making it to meet everyone's requirements.
