柔性石墨密封材料在真空或惰性介质中,可以在-200～2,000℃范围内使用。在石油化工中,用以制作各种垫片、填料、密封圈等,具有耐高低温、耐温度骤变等优点。这种材料已经一机部上海材料研究所研制成功,产品主要性接近或达到国外同类产品水平,上海炼油厂与该所协作,已初步取得多项试用成功: 催化裂化烟气能量回收中,用作耐温640℃以上(短时可达740℃)、压力2.5公斤/厘米~2(绝)、口
Flexible graphite sealing materials in vacuum or inert medium, can be -200 ~ 2,000 ℃ range of use. In the petrochemical industry, to produce all kinds of gaskets, packing, seals, etc., with high temperature, temperature resistance and other advantages. This material has been successfully developed by Shanghai Institute of Materia Medica, a part of the company. Its main products are close to or reach the level of similar foreign products. In cooperation with Shanghai Refinery, a number of trial successes have been initially achieved. In the energy recovery of FCC flue gas, For temperature above 640 ℃ (short-term up to 740 ℃), pressure 2.5 kg / cm ~ 2 (absolutely), the mouth
