石墨转子是什么
石(shi)(shi)墨(mo)转子是(shi)一(yi)种以石(shi)(shi)墨(mo)材料为(wei)核心制成的(de)旋(xuan)转部件(jian),广(guang)泛应用(yong)于高(gao)(gao)(gao)温(wen)(wen)、腐蚀性(xing)或石(shi)(shi)墨(mo)转子凭借其(qi)独特(te)(te)(te)性(xing)能(neng),已成为(wei)高(gao)(gao)(gao)温(wen)(wen)、腐蚀工(gong)况下的(de)关键部件(jian),其(qi)应用(yong)深度和广(guang)度将持(chi)续拓展。特(te)(te)(te)殊(shu)工(gong)艺环境中(zhong),其(qi)核心特(te)(te)(te)性(xing)源(yuan)于石(shi)(shi)墨(mo)的(de)独特(te)(te)(te)物理和化学性(xing)质。核心材料:石(shi)(shi)墨(mo)的(de)熔点高(gao)(gao)(gao)达约3650°C,在惰性(xing)气(qi)氛(fen)中(zhong)可(ke)长期(qi)稳定工(gong)作于2500°C以下,短期(qi)甚至(zhi)能(neng)承受3000°C以上高(gao)(gao)(gao)温(wen)(wen),远超大多数金属材料。在常温(wen)(wen)下,石(shi)(shi)墨(mo)对酸(suan)、碱及有(you)机溶剂具有(you)极强抗腐蚀性(xing);高(gao)(gao)(gao)温(wen)(wen)下虽可(ke)能(neng)被强氧化性(xing)物质(如浓硝酸(suan)、浓硫酸(suan))侵蚀,但在惰性(xing)或还(hai)原性(xing)气(qi)氛(fen)中(zhong)(如氢气(qi)、氩气(qi))仍能(neng)保持(chi)稳定。
