Kubbadaha alumina ee adkaysi u leh waxay leeyihiin tayo wanaagsan oo ah xoog sare, adkaysi sare, awood xoqid oo aad u fiican, cufnaanta cufan ee mugga, waxqabadka heerkulka sare, iska caabbinta daxalka, wasakhowga yar iyo sifooyin kale oo aad u fiican. Kubbadaha alumina waxaa si weyn loogu isticmaalay dhammaystirka iyo farsamaynta qoto dheer ee noocyada kala duwan ee dhoobada, dhaldhalaalka, galaaska, kiimikooyinka iyo walxaha kale ee qaro weyn iyo kuwa adag.
Sifooyinka Kubbadaha Alumina ee aan la isticmaalin
- Iska caabinta Heerkulka Sare
- Iska caabinta Kulaylka Wanaagsan
- Xoog Farsamo Sare
- Cimri Dheer oo Adeeg ah
Halabuurka Kubbadaha Alumina ee aan la isticmaalin
Kubbadaha alumina ee adkaysi u leh waxaa laga sameeyay AL2O3, kaolin, isku-darka synthetic, kiristaalka mullite iyo agab kale. Sida waafaqsan habka duubista iyo habka wax lagu sameeyo ee riixista, kubbadaha adkaysi u leh aluminiumku waxay leeyihiin faa'iidooyin ah xoog sare, iska caabin shoogga kulaylka oo wanaagsan, beddel habboon iyo nadiifin, cimri dheer oo adeeg ah iwm.
Habka Kubadaha Alumina ee aan la adkeyn karin
Si loo sameeyo kubbado alumina ah oo aan dhalaalin, elektaroodhka waxaa la dhigayaa salka hoose ee graphite crucible, qaansadana waxaa lagu bilaabi karaa iyadoo lagu darayo xaddi cayiman oo budada alumina warshadaha ah. Hadda shaqeynaya 1.0kA, danab 80~100V. Ka dib marka la garaaco, sida Al2O3 u dhalaalayso, si tartiib tartiib ah ayuu u rarayaa, ilaa dareeraha maaddada uu ka buuxo graphite crucible, heerkulka dareeraha ee maaddada waa 2200 ~ 2300 ℃. Intaa ka dib, charcible-ka waa la shubayaa oo xalku wuu soo baxayaa.

Codsiga Kubadaha Alumina ee aan la adkeyn karin
Kubbadaha alumina ee alumina-ka ah ayaa si weyn loogu isticmaalay dhammaystirka iyo farsamaynta qoto dheer ee noocyada kala duwan ee dhoobada, dhaldhalaalka, galaaska, kiimikooyinka iyo agab kale oo qaro weyn oo adag. Gaar ahaan kubbadaha alumina-ka ah ee adkaysiga leh ee ku habboon qalabka kala-soocidda hawada ee qalabka kala-soocidda kulaylka iyo foornada birta ah ee gaaska kululaynta sida buuxinta kaydinta kulaylka.
