JM26 Mullite Insulation Brick
JM26 Mullite Insulation Brick
Refractoriness na JM26 tubalin mullite zai iya kaiwa sama da 1790 ℃. Zazzabi mai laushi yana farawa zafin jiki shine 1400. Ƙarfin matsawa a zafin jiki na ɗakin shine 3-8MPa. Good thermal buga juriya. Akwai nau’o’in tubalin mullite iri biyu da tubalin mullite. An yi tubalin mullite na katako da babban alumina bauxite clinker a matsayin babban kayan albarkatun ƙasa, yana ƙara ƙaramin yumɓu ko bauxite a matsayin mai ɗauri, da kuma yin harbe-harbe. An yi tubalin mullite na manyan alumina, alumina na masana’antu da yumɓu mai ƙyalƙyali azaman kayan masarufi, kuma ana ƙara gawayi ko barbashi mai kyau a matsayin masu ragewa. Bayan gyare -gyaren, ana ƙera su ta hanyar rage narkewar lantarki. Cristallization na fushin mullite ya fi girma fiye da na mullite mai ɓarna, kuma juriyarsa na zafi ya fi na samfuran da aka lalata. Babban aikin zafin su yafi dogara ne da abun ciki na alumina da daidaiton lokacin mullite da rarraba gilashi. Zuwa
An yi bulo mai rufi na JM26 mullite na babban bauxite clinker a matsayin babban kayan, da ƙaramin yumɓu. Yana kare albarkatun yumbu da kyau, don haka lokacin da tubalin rufin mullite ya bayyana, sun kasance samfuran fasahar zamani. A da, aluminium wani abu ne da manyan mutane za su iya amfani da su. Koyaya, fasahar zamani ta ba da damar aluminium a matsayin hanya don amfani da samfuran iri daban -daban.
Amfani da zafin jiki na abubuwa daban -daban na jumlolin mullite na jM na iya zama daga digiri 1300 zuwa digiri 1600, kuma ƙimar jiki na iya zama 0.6, gwargwadon buƙatun mai amfani.
Tsakanin 0.8, 1.0 da 1.2, yana aiki akan tanderu mai tsananin zafi don tuntuɓar harshen wuta kai tsaye, kuma yana da halayen tasirin rufi mai kyau, ƙarfin matsi mai ƙarfi, da ƙarancin yanayin zafi. Ya dace da ruɓaɓɓen murƙushe wutar lantarki, ɗimbin juzu’i masu jujjuyawa daban-daban, kiln rami, gas gas na nitrogen, da dai sauransu. Cristallization na fused mullite ya fi na sinadarin mullite ƙanƙara, kuma juriyarsa ta zafi ya fi na sintered samfurori. Babban aikin zafin su yafi dogara ne da abun ciki na alumina da daidaiton lokacin mullite da rarraba gilashi. Ana amfani da tubalin Mullite mafi yawa don saman murhun murhun wuta, jikin murhun wuta da ƙasa, mai gyara murhun murɗa wuta, murhun yumɓu mai ƙyalƙyali, matattarar kusurwar tsarin fasa bututun mai, da sauransu.
