Polyurethane rollers are more and more widely used, polyurethane rollers are composed of metal core, adhesive layer and covered polyurethane rubber layer, in the process of making rollers, in order to improve quality, the technical requirements for the corresponding metal core are as follows: the material of the metal roller core can be cast iron or steel plate, steel pipe and other metal materials.
Polyurethane rollers are more and more widely used, polyurethane rollers are composed of metal core, adhesive layer and covered with polyurethane rubber layer, in the process of making rollers, in order to improve quality, the technical requirements for the corresponding metal core are as follows:
1. The material of the metal roller core can be cast iron or steel plate, steel pipe and other metal materials. The wall thickness of cast iron cores is generally not less than 10mm. The wall thickness of the roller core made of steel plate or steel pipe should comply with the regulations;
2. The metal roller core is a hollow cylinder, and the wall thickness should be uniform and consistent;
3. The structural size and surface processing of the metal roller core should comply with the provisions of the agreement between the production and the user;
4. The metal core surface of the polyurethane roller shall not have defects such as trachoma and pores;
5. The shaft of the metal core must have center holes at both ends;
6. The metal core of the polyurethane roller should have the requirements of the physical tolerance (runout, coaxiality, cylindrical degree), and be consistent with the rubberized polyurethane roller;
7. The requirements for the static balance of metal cores shall be agreed upon by both supply and demand.
Polyurethane rollers are widely used in papermaking, steel, printing and dyeing, textile and other industries. Strictly in accordance with the requirements of metal core production polyurethane rollers, to ensure quality, is conducive to improve the production efficiency of various industries.
