胶辊表面粗糙度的控制实践

Surface Roughness Control Practice of Rubber-coverd Roll

阐述影响胶辊表面粗糙度的因素,探讨胶辊表面粗糙度与纺纱质量的关系。简述了胶辊表面粗糙度的形态特征,从胶辊的磨砺、磨削量、回磨次数、硬度、表面处理等方面分析,确定合理的胶辊表面粗糙度的范围。指出:应根据纺纱工艺的要求、配棉混纺的成分、纤维的性能来确定胶辊表面粗糙度,才能使胶辊上机不缠花,从而稳定提高纺纱质量。要根据纺纱生产的实际情况,确定胶辊表面粗糙度和粗糙度不匀,以充分发挥胶辊在纺纱中的重要作用。

Factors affecting surface roughness of rubber-coverd roll were elaborated,relationship between surface roughness of rubber-coverd roll and spinning quality was discussed.Surface roughness morphological characteristics of rubber-coverd roll were briefly described.Analyzed from the aspects of grinding,grinding amount,grinding times,hardness and surface treatment of rubber-coverd roll,reasonable surface roughness range of rubber-coverd roll was determined.It is pointed out that surface roughness of rubber-coverd roll should be determined according to requirements of spinning process,composition of blended cotton assorting and properties of fiber,so that rubber-coverd roll would not be entangled and spinning quality can be stably improved.According to actual situation of spinning production,surface roughness and roughness eveness of rubber-coverd roll should be determined to fully play the important role of rubber-coverd roll in spinning.
