Imipira ya Alumina ivunika ifite ubwiza bwimbaraga nyinshi, gukomera kwinshi, ubushobozi bwiza bwo gukuramo, ubwinshi bwinshi, imikorere yubushyuhe bwinshi, kurwanya ruswa, kwanduza gake nibindi bintu 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 Imipira
- 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, gusimbuza byoroshye no gukora isuku, ubuzima bwigihe kirekire nibindi.
Inzira ya Alumina Yumubyimba
Kugirango ukore imipira ya alumina ivunika, electrode ishyirwa hepfo ya grafite ikomeye, kandi arc irashobora gutangira wongeyeho umubare munini wifu ya alumina yinganda. Gukoresha ubu 1.0kA, voltage 80 ~ 100V.Nyuma yo gukubita, nkuko Al2O3 yashongeshejwe, ikapakira buhoro buhoro, kugeza igihe ibintu byuzuye byuzuyemo grafitike, ubushyuhe bwamazi ni 2200 ~ 2300 ℃ .Nyuma yibyo, igikonjo kirasukwa 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 ikwirakwiza ibikoresho byo gutandukanya ikirere hamwe nubushyuhe bwa gaz itanura rya gaz nkububiko bwubushyuhe
