活化填充聚四氟乙烯软板,是以聚四氟乙烯为基础材料,添加青铜粉、炭纤维、玻璃纤维、石墨、二硫化铝等填充剂经加工而成。为了提高粘接强度,在其表面进行化学活化处理。这种材料具有摩擦系数小、移动轻快、耐磨和防止低速爬行的特点,有自润滑性,可以保护机床导轨面不拉伤,延长机器使用寿命。在设备维修中,多用于各种机床滑动导轨面的粘接,以恢复其精度。开始,我们将其用于中小型机床上,现用于大型机床上获得了成功。我们从日本进口的大型专用铣床,在使用中由于多种原因,使两个铣头的滑鞍导轨面严重拉伤,拉伤面积达90％以上,拉伤深度达2.5毫米。两个平导轨面宽为300毫米。有两个主导轨面和两个副导轨
Activated filling polytetrafluoroethylene soft board, based on PTFE as the base material, add bronze powder, carbon fiber, glass fiber, graphite, aluminum disulfide and other fillers processed. In order to improve the bonding strength, the surface of the chemical activation treatment. This material has the characteristics of small friction coefficient, moving light, wear-resistant and prevent low-speed crawling, self-lubricating, can protect the machine rail surface is not strain, extend the service life of the machine. In equipment maintenance, used for a variety of machine sliding guide surface bonding to restore its accuracy. At the beginning, we used it for small and medium-sized machine tools and are now successful on large machine tools. We imported from Japan for large-scale special milling machine, in use for a variety of reasons, so that the two rail head saddle rail face serious strain, more than 90% of the injury area, strain of up to 2.5 mm. Two flat rail surface width of 300 mm. There are two main rails and two sub rails
