摘要(Abstract):

本文通过对酚醛纤维浸渍聚四氟乙烯填料的摩擦系数、磨耗量、压缩回弹、应力松弛、热失重等项性能的研究以及作为阀门密封填料的模拟工况寿命试验,分析了该种密封填料的优缺点。现场使用结果表明,该填料无污染,价格与石棉四氟编织填料相仿,是代替石棉的较理想的密封填料。
The advantages and disadvantages of the packing are analysed through research on the various performances of phenol-fibre impregnating PTTE packing and the test for the simulation operation lifetime of the packing in valve-sealing. On-side operation results showed that gives no environmental pollution and its market price is comparable to that of weaven asbestos PTTE packing.
