Imipira ya Alumina ivunika ifite ubuziranenge bwiza bwimbaraga nyinshi, gukomera kwinshi, ubushobozi buhebuje bwo gukuramo, ubwinshi bwubwinshi bwimbaraga, imikorere yubushyuhe bwinshi, kurwanya ruswa, umwanda muke nibindi byiza byiza. imipira ya alumina yakoreshejwe cyane mukurangiza no gutunganya byimbitse ubwoko butandukanye bwa ceramic, enamel, ikirahure, imiti nibindi bikoresho binini kandi bikomeye.
Ibyiza bya Alumina Yumupira
- Kurwanya Ubushyuhe Bwinshi
- Kurwanya Ubushyuhe bwiza
- Imbaraga Zikomeye
- Ubuzima Burebure
Ibigize imipira ya Alumina
Imipira ya Alumina ivunika ikozwe muri AL2O3, kaolin, igiteranyo cyogukora, kristu ya mullite nibindi bikoresho. Ukurikije kuzunguruka hamwe nuburyo bwo gukanda. imipira ya aluminium yamashanyarazi ifite ibyiza byimbaraga nyinshi, guhangana nubushyuhe bwiza bwumuriro, gusimburwa byoroshye no gukora isuku, ubuzima bwa serivisi ndende nibindi.
Inzira ya Alumina Yumubyimba
Kugirango dukore imipira ya alumina yangiritse, electrode ishyirwa hepfo ya grafite ikomeye, kandi arc irashobora gutangira wongeyeho umubare munini wifu ya alumina yinganda. Gukoresha amashanyarazi 1.0kA, voltage 80 ~ 100V.Nyuma yo gukubita, nkuko Al2O3 yashongeshejwe, igapakira buhoro buhoro, kugeza amazi yibintu yuzuyemo grafite ya grafitike, ubushyuhe bwamazi yibintu ni 2200 ~ 2300 ℃ .Nyuma yibyo, ingenzi irasukwa kandi igisubizo. isohoka.

Gushyira mu bikorwa imipira ya Alumina
Imipira ya Alumina ivunika yakoreshejwe cyane mukurangiza no gutunganya byimbitse ubwoko butandukanye bwa ceramic, enamel, ikirahure, imiti nibindi bikoresho binini kandi bikomeye. Cyane cyane imipira ya aluminiyumu ikwiranye nibikoresho byo gutandukanya ikirere hamwe nubushyuhe bwo gutwika ibyuma hamwe nicyuma gishyushya itanura nkububiko bwubushyuhe
