I talked about the use of PTFE for anti-corrosion and sealing. Today, we will introduce the third type of load-bearing, which is mostly used for roller protection, various rods, tubes, sheet films, belts, ropes, packing, gaskets, and Graphite, molybdenum disulfide, aluminum oxide, glass fiber, and carbon fiber are used as fillers to improve the mechanical properties of pure PTFE. It can be roughly divided into the following categories: anti-corrosion; sealing; load-bearing; insulation ; Anti-sticking category; Temperature resistant category; Other medical category

Three, bearing class

1. Filled with PTFE bearings, used in food, chemical, papermaking, textile machinery;

2. Porous copper-impregnated fluoroplastic metal bearings can be used normally under high temperature, high pressure, dry friction, and vacuum conditions;

3. The bearing lining made of composite fabric made of PTFE fiber blended with glass fiber or other fiber of PTFE fiber bearing is used for low speed and high load;

4. Filled with PTFE piston ring, guide ring, machine tool guide rail and bridge slider;

聚四氟乙烯用于承荷类

前面讲了聚四氟乙烯用于防腐类，密封类，今天介绍第三类承载类，多用于滚轴保护，各种棒、管、板膜、带、绳、盘根、垫片,及用石墨、二硫化钼、三氧化二铝、玻纤、碳纤维作为填充物,来提高纯聚四氟乙烯力学性能.大致可以分为以下几大类，防腐类；密封类；承荷类；绝缘类；防粘类；耐温类；其他类医用类

三、承荷类

1.填充聚四氟乙烯轴承，用于食品化工造纸、纺织机械；

2.多孔铜浸渍氟塑料金属轴承，可在高温高压干摩擦、真空条件下正常使用；

3.聚四氟乙烯纤维轴承的聚四氟乙烯纤维与玻纤或其他纤维混纺的复合织物制成的轴承内衬，用于低速高负荷；
