炭石景材料促进了现代科学技术的大发展,人造石墨电极的成果攻克了当今电炉炼钢的难关,石墨密封材料推动了机械工业、精密仪器、高速旋转发动的进步。现代科学技术的大发展,又同时要求提供性能崭新的炭石墨材料。普通石墨材料的强度和气密性,除了浸渍树脂与低溶点金属合金之外,是否有更简单的工艺呢?本文通过试验研究认为.化学浸银可以提高普通人造石墨的强度和气密性。试验方法:金属浸渍方法是将已高温熔融金属压入炭石墨材料内孔表面,其压力在10atm,甚至100atm以上。而现住采用熔融硝酸银,将已准备好的
Carbon stone scene material to promote the great development of modern science and technology, artificial graphite electrode overcome the current difficulties in EAF steel, graphite seal material to promote the machinery industry, precision instruments, high-speed rotation of the progress. The great development of modern science and technology, but also requested the performance of new carbon graphite materials. Ordinary graphite material strength and air tightness, in addition to impregnating resin and low melting point metal alloy, whether there is a more simple process? This paper through experimental studies suggest that chemical immersion silver can improve the ordinary artificial graphite strength and air tightness. Test Method: The method of metal impregnation is to press the hot molten metal into the inner surface of the carbon graphite material with a pressure of 10 atm and even over 100 atm. Now living with molten silver nitrate, will be ready
