浙江慈溪密封材料厂与机械工业部上海内燃机研究所合作,自1983年起将膨胀石墨这种新型密封材料用来作为内燃机气缸垫,开展了试验研究,旨在解决现行气缸垫密封性能差,使用寿命短的问题。为了使这种材料能用于内燃机气缸的密封,首先研制成由薄金属板与柔性石墨组成的复合板,其主要技术指标如右表: 由柔性石墨复合板材冲制成的解放、东风及上海牌等车型的发动机气缸垫,经过台
Cixi, Zhejiang, sealing materials plant and the Ministry of Machinery Industry, Shanghai Institute of Internal Combustion Engineers since 1983 will be expanded graphite as a new sealing material used as cylinder engine gasket, conducted a pilot study to address the current cylinder gasket sealing performance is poor, the use of Short life expectancy. In order to make this kind of material suitable for the sealing of the cylinder of the internal combustion engine, the composite board made of thin metal plate and flexible graphite is first developed. Its main technical indexes are shown in the table on the right: Jiefang, Dongfeng and Shanghai made of flexible graphite composite sheet Licensing and other models of the engine cylinder pad, after Taiwan
