試験するガスケットを、セルのフランジと覆いとの間でＩＩキログラムのボルト トルクにｊ″でポル１−締めする。この完成した系を２４０℃に維持した空気炉 に入れ、３時間かけて加熱して、あらかじめ決定されている３２バールの内部水 圧を生む。この系を炉から取り出し、３時間、室温で放冷する。このす、イクル を４０［１まで繰り返す。The gasket to be tested is connected with II kilogram bolts between the flange of the cell and the shroud. Tighten to a torque of J''. Place this completed system in an air furnace maintained at 240°C. and heated for 3 hours to create a predetermined internal water pressure of 32 bar. generate pressure. The system is removed from the oven and allowed to cool at room temperature for 3 hours. This is Ikuru Repeat until 40 [1.
各試験ガスケットに関する百分率水分損失（４回の試験の平均値）を表１に示し である。加えて、アスベストとケブラー２パルプとの市販のガスケット（Ｃ）に 対する本発明記載のガス炉・ソト（ＡおよびＢ）ｌこ関する低い水分損失を示し 得るように、水分損失を拡大スケールで点描しである。The percentage water loss (average of four tests) for each test gasket is shown in Table 1. It is. In addition, a commercially available gasket (C) made of asbestos and Kevlar 2 pulp The gas furnaces according to the invention (A and B) exhibit low moisture loss relative to As obtained, water loss is stippled on an enlarged scale.
