PTFE的摩擦因数随滑动速率的增大而增大，当线速度达到0.5一1.0m/s以上时趋于稳定;而且静摩擦因数小于动摩擦因数，将这种特性用于轴承制造，可减小其起动阻力，使之从起动到运转都十分平稳。PTFE的摩擦因数随随载荷增加而减小，当载荷达到0.8MPa以上时趋于恒定。在高速、高载荷下，PTFE的摩擦因数低于0.01。从超低温到PTFE熔点，
The friction factor of PTFE increases with the increase of the sliding rate, and tends to be stable when the line speed reaches 0.5 or more 1.0m/s, and the static friction factor is less than the dynamic friction factor. This characteristic is used in the bearing manufacturing, and the starting resistance can be reduced, so it is very stable from starting to operation. The friction coefficient of PTFE decreases with increasing load, and tends to be c***tant when the load reaches 0.8MPa. Under high speed and high load, the friction coefficient of PTFE is less than 0.01. From ultra low temperature to PTFE melting point,
其摩擦因数几乎不变，只有在表面温度高于熔点时，摩擦因数为才急剧增大。
The friction coefficient is almost unchanged. Only when the surface temperature is higher than the melting point, the friction coefficient will increase sharply.
由于分子间引力小，PTFE的硬度低，易被其他材料磨损。但是，只要对磨材料表面粗糙度合适，可在相当程度上降低PTEF的磨损量。
Because of the ***all intermolecular attraction, PTFE has low hardness and is easily worn by other materials. However, as long as the surface roughness of the grinding material is suitable, the wear volume of PTEF can be reduced to a certain extent.

TEP :F－46具有较好的加工工艺性能。可采用通常的挤出法包覆电线电缆的绝缘层。为了正确设计挤出机和模具，控制和掌握F－46树脂的加工条件，首先应了解F－46的流变性能。F－46在390℃温度下剪切应力与剪切速率的关系。其粘度μA随剪切速率加而下降。 F－46的临界剪切速率，如果剪切速率超过此数值，就会引起塑料流动的下均匀，结果使制品表面粗糙，无光泽和起层。F－46的临界剪切速率值与聚 ，尼龙相比相差悬殊，因而熔融***问题尤为严重。pc 8210-31
TEP: F - 40 has good processing performance. The insulation layer of wire and cable can be covered by usual extrusion method. In order to correctly design extruders and moulds, control and master the processing conditi*** of F - 40 resins, we should first understand the rheological properties of F - 40. The relati***hip between shear stress and shear rate at temperature of 390? The viscosity of A decreases with the shear rate. The critical shear rate of F - 46, if the shear rate exceeds this value, will lead to the uniform flow of the plastic, which results in rough surface, luster and layer. The critical shear rate of F4 is quite different from that of poly (nylon), so the problem of melt fracture is particularly serious. PC 8210-31

F－46树脂在加工中有两个特征，即具有熔融***的倾向和熔融状态时有特高的可拉伸性。为了在电线电缆生产中尽量消除或改善熔融***和提高生产率，通常采取以下措施：diyi，采用挤管式模具，扩大模子的开口，以减慢聚合物在模口的流速，使之在低于临界剪切速率的适中挤出速度下挤出树脂，并提高生产率；第二，在不致使树脂分解的前提下，尽可能提高熔融树脂的温度，以降低树脂粘度，从而提高其临界剪切速率
There are two characteristics in the processing of F - 46 resin, that is, the tendency to melt and break and the high tensile property when melting. In order to eliminate or improve melt fracture and increase productivity as far as possible in wire and cable production, the following measures are usually taken as follows: Diyi, using a extruded die to expand the opening of the mold to reduce the flow velocity of the polymer at the die mouth so that the resin is extruded at a moderate extrusion speed below the critical shear rate, and the productivity is increased. Second, without causing the decomposition of resin, the temperature of melted resin can be raised as far as possible, so as to reduce the viscosity of resin and increase its critical shear rate.
