一、引言PTFE是聚四氟乙烯的英文缩写。它具有较高的化学稳定性,在所有固体材料中摩擦系数最低,温度范围宽,同时防粘性能亦厲上乘,因而在工业领域中的应用日趋广泛。PTFE树脂在助剂作用下,分散于水相中即得到PTFE悬浮液。喷涂于各种基材表面并经烘烤固化即成PTFE涂层。我厂研制的G146B浆纱机上,有一φ800×200p毫米的1Cr18Ni9Ti不锈钢烘筒,要求外工作面既有高度的化学稳定性,可耐高温(T=
First, the introduction of PTFE PTFE is the English abbreviation. It has a high chemical stability, the lowest coefficient of friction in all solid materials, wide temperature range, while also excellent anti-sticking performance, which in the field of industrial applications increasingly widespread. PTFE resin in the role of additives, dispersed in the aqueous phase to obtain PTFE suspension. Sprayed on a variety of substrate surface and baked to become PTFE coating. Our factory developed G146B sizing machine, there is a φ800 × 200p mm 1Cr18Ni9Ti stainless steel drying cylinder, requiring both the outer face of a high degree of chemical stability, high temperature (T =
