根据国内外无石棉密封材料的发展和应用，采用橡胶模压工艺，以芳砜纶纤维代替石棉纤维作为增强材料，研制开发了一种无石棉垫片密封板材，并利用正交试验设计法研究了影响材料基本性能的主要因素，确定了较好的材料组成和工艺条件
According to the development and application of non-asbestos sealing materials both at home and abroad, a non-asbestos gaskets sealing plate was developed by using rubber molding technology and polysulfone fiber instead of asbestos fibers. The orthogonal test design method was used to study The main factors affecting the basic properties of the material to determine the better material composition and process conditions
