Abstract
Characteristics and application of polyurethane rubber-covered roll were discussed. Problems of nitrile rubber-covered roll were analyzed. Basic property, manufacturing methods and application features of polyurethane rubber-covered roll were introduced. The spinning performance of polyurethane rubber-covered roll and nitrile rubber-covered roll was contrasted. The result shows that there are many advantages for polyurethane rubber-covered roll,such as better elasticity and wearability ,smaller deformation, thermal insulation and vibration absorption, stable hardness,resistance to oil & light & ozone, stronger anti-aging cracking, better antistatic and absorbing or releasing moisture after adding antistatic agent or conductive composition. It is proved by long time comparison test,the spinning yam quality and anti-winding is better than that of nitrile rubber-covered roll. The grinding cycle and life are longer than of nitrile rubber-covered roll. Currently,it is considered that each property demands of rubber-covered roll can be satisfied well by adopting pouring processing. Yarn quality can be improved, spinnability of rubber-covered roll can be increased and production cost can be reduced by using polyurethane rubber-covered roll.关键词
