Zirconium Mullite Brick

Fa’idodin samfur: babban ƙima mai yawa, ƙarar girma, babban ƙarfin injiniya a ɗakin zafin jiki da babban zafin jiki, kwanciyar hankali mai ɗorewa mai ɗorewa, ƙarancin ƙonawa da raguwar zafin zafin jiki, da kyakkyawan kwanciyar hankali na sinadarai da juriya ga kafofin watsa labarai na alkaline.

Amfani mai wadatarwa: Layin samarwa mai ƙyalƙyali mai fasaha ta atomatik, isar da ƙasa

Aikace -aikacen samfur: An fi amfani da shi a cikin mahimman sassan kilns kamar gilashin gilashi, kiln fiber na gilashi, ƙusoshin ulu na dutsen, ƙona kona shara, yumɓu mai ƙyalli mai ƙyalƙyali, murhun wutar lantarki, da sauransu.

Zirconium mullite tubalin yana inganta tsarin mullite ta hanyar gabatar da ZrO2 cikin tubalin A12O3-SiO2, wanda zai iya haɓaka juriya na sunadarai, juriya mai ɗorewar zafi da rage adadin maɗaukakin mullite. An yi shi gabaɗaya ta hanyar electrofusion. Hakanan ana samun sa ta hanyar nutsewa.

Zirconium mullite tubali abu ne mai ƙyalƙyali na musamman wanda aka yi ta amfani da alumina na masana’antu da zircon mai da hankali azaman kayan albarkatu da gabatar da zirconia a cikin matrix mullite ta hanyar tsarin nutsewa mai aiki.

Zirconium mullite tubalin yana gabatar da zirconia a cikin tubalin mullite, kuma canjin lokaci na tsaurin zirconia na iya haɓaka ƙimar kayan aikin zafin jiki na kayan mullite. Zirconia yana haɓaka narkar da kayan mullite. Bugu da ƙari na ZrO2 na iya hanzarta haɓakawa da nutsewar kayan ZTM saboda ƙaruwar ƙananan abubuwan narkewa da samuwar guraben aiki. Lokacin da guntun taro na zirconium mullite tubalin shine 30%, ƙarancin ka’idar ka’idar koren jikin da aka harba a 1530 ° C ya kai 98%, ƙarfin ya kai 378MPa, kuma taurin ya kai 4.3MPa · m1/2.

Ana yin tubalin mirite na zirconium daga alumina na masana’antu da zircon ta hanyar nutsewa. Saboda dauki da sintering ana aiwatar da su a lokaci guda, sarrafa tsari yana da wahala. Gabaɗaya, tubalin mullite na zirconium yana da zafi a 1450 ° C don sa su yi yawa yayin harbi, sannan a mai da su zuwa 1600 ° C don ɗaukar nauyi. ZrSiO4 ya ruɓe cikin ZrO2 da SiO2 a zafin jiki mafi girma fiye da 1535 ° C, kuma SiO2 da Al2O3 suna amsawa don samar da Mullite Stone, saboda wani sashi na lokacin ruwa yana bayyana yayin rarrabuwa na ZrSiO4, kuma bazuwar ZrSiO4 na iya tace barbashi, ƙaruwa takamaiman yanki, da haɓaka sintering.
