一、前言近几年来,气动技术在自动化、节能等方面受到了产业界的好评。气缸的需求量也不断增加。从润滑维护和防止环境污染的观点出发,目前的气动系统已迅速向无润滑方面发展,对气缸的要求亦是如此。现在无润滑气缸已作为标准件在市场上出售。华尔卡工业公司开发了一种新型的无润滑气缸所使用的“TAFURIRU”密封材料。并已着手进行标准化的工作。这种密封材料与一般的NBR(丙烯腈橡胶)相比,具有更好的耐磨性及变形恢复能力等特点,它是一种无润滑密封材料。
First, the foreword In recent years, pneumatic technology in the automation, energy saving and other aspects of the industry has been praised. Demand for cylinders is also on the rise. From the standpoint of lubrication maintenance and prevention of environmental pollution, the current pneumatic system has rapidly developed to a non-lubricated, as well as to cylinder requirements. Non-lubricated cylinders are now on the market for sale as standard parts. WALKER INDUSTRIES has developed a new “TAFURIRU” sealing material for use in non-lubricated cylinders. It has also started work on standardization. Compared with the general NBR (acrylonitrile rubber), this kind of sealing material has the characteristics of better abrasion resistance and deformation recovery ability, and it is a non-lubricating sealing material.
