四氟盘根 PTFE packing 型号 Type 聚四氟乙烯类盘根 types of PTFE packing TD-650 白四氟盘根 PTFE packing TD-650Y 含油白四氟盘根 PTFE packing with oil TD-650SC 白四氟盘根硅胶芯盘根 PTFE packing with rubber core TD-650YC 含油白四氟盘根硅胶芯盘根 PTFE packing with oil & rubber core 白四氟乙烯盘根,又称洁净型耐腐蚀盘根。该盘根由聚四氟乙烯线制成的编织盘根。不浸渍任何聚四氟乙烯乳液和油脂类。聚四氟乙烯具有很多优良的特性,耐腐蚀,自润滑,不粘贴。但也存在传热差,热膨胀系数大,有冷流等缺点。 The packing is a braided packing made from PTFE dispersion and lubricant are not impregnated。PTFE has characteristics of excellent anticorrosion, good self-lubrication and non-sticking. However, it is also substance with low heat conductivity, cold flow and great thermal expansion coefficient. 适用于压力不高的阀门及转速较低的应用,但对介质的纯度及抗腐蚀性有较高要求的地方,如:食品行业、医药、造纸、化纤等。 Designed for valves and lower shaft speed applications under medial pressure in food processing, pharmaceuticals, paper mills, fibre plants where high purity and corrosion resistance is required. 服务范围 SERVI
