石棉橡胶板是用于化工、化纤、原子能、热电厂等工矿企业设备及法兰联接处的密封材料。因为普通石棉橡胶板中含有较多的氯离子,它对金属法兰产生较强的腐蚀,对不锈钢法兰腐蚀更厉害。为此国外一些先进国家在80年代初期开始研制低氯离子的橡胶板,其氯离子含量为≤100ppm。我国目前使用的低氯离子的橡胶板主要依靠进口,每年耗费大量外汇。我厂于1986.10开始研制低氯缓蚀石棉橡胶板(简称低氯板)。1988年初在实验室试制成功的基础上继续扩大实验,取得可喜的效果。目前我厂已送北京燕山石化总公司、上海金山石化总厂等7个化工、化纤单位试验使用一年多,均反映性能良好。深受欢迎。
Asbestos rubber sheet is used for chemical, chemical fiber, atomic energy, thermal power plants and other mining equipment and flange joints at the sealing material. Because ordinary asbestos rubber sheet contains more chloride ions, it has a strong metal flange corrosion, corrosion of stainless steel flange more powerful. To this end some foreign advanced countries in the early 80s began developing low chloride ion rubber plate, the chloride ion content of ≤ 100ppm. The low chloride ion rubber plate currently used in our country mainly relies on imports, consuming a large amount of foreign exchange every year. I plant in 1986.10 began developing low chloride corrosion asbestos rubber sheet (referred to as low-chloride plate). In early 1988 based on the success of the laboratory trial continued to expand the experiment, and achieved gratifying results. At present, I plant has been sent to Beijing Yanshan Petrochemical Corporation, Shanghai Jinshan Petrochemical Plant and other seven chemical, chemical fiber unit test more than a year, all reflect the good performance. very popular.
