用低级石棉生产高强度、大弧度、薄形摩擦材料,目前在国内外都是一个研究课题。过去,大弧度、薄形刹车片都是以石棉布或石棉线作为主填料的,但是制品摩擦性能始终达不到“建标”要求;石棉布或石棉线本身价格也较贵,冉加上纺织时粉尘污染极其严重,问题较多。我们希望以目前生产常用的短纤维石棉为主填料,并掺用网格玻璃布,以求达到既扩大低级棉的使用,又保证制品质量的目标。 Low-grade asbestos production of high strength, large arc, thin friction material, at home and abroad are currently a research topic. In the past, the large radian and thin brake pads were mainly made of asbestos or asbestos, but the friction performance of the products did not meet the requirements of “building standard”; asbestos or asbestos itself was more expensive, Textile dust pollution is extremely serious, more problems. We hope that the current production of commonly used short fiber asbestos-based filler, and mixed with grid glass cloth, in order to achieve both to expand the use of low-grade cotton, but also to ensure product quality goals.
