(WintrustekItanga byombiAluminakandiMullite)
Alumina ceramic, rimwe na rimwe bivugwa nkaaluminium oxide (al2o3) or alumina, ni impyisi yinganda zinganda zigenda neza kandi ziramba cyane. Kubera imico yabo,Alumina Ceramicsbari mu banyabwenge bazwi cyane ku byaro, kwambara, n'imiterere y'icyuma. Mubisanzwe bikozwe muri bauxite, ceramics ya alumina irashobora kubumbwa no kwibumbanwa, gushinga imitekerereze, gupfa, gukanda yinda, kunyerera, kunyerera, na diyama.
Mulliteikorwa no guhuza silica na alumina muburyo butandukanye mugihe cyimikorere, bitera ibikoresho bitandukanye. Ku gitsina gabo, cyitwa Mullite; Ku amanota meza, byitwa Pullite mullite cyangwa korim.
Hariho ubwoko bubiri bwa synthetic mullite (al2o3-sio2): kubahwa kandi bidafite ishingiro. Imbaraga nyinshi nimbaraga zidasanzwe zo guhungabanya ubushyuhe zihujwe nabi (udahakana) mullite. Kwagura ibibanza bya mullite bike kandi ugereranije nimbaraga nyinshi zitanga urwego ruteye ubwoba bwo guhungabana.
Mullite ceramicsbakoreshwa mu mashanyarazi, itanura, gushyushya, no kwambara no gutangaza no kwambara kubera ubushyuhe bwo hejuru bukabije kandi bukora ubushyuhe bwo hejuru no ku ya 2910f (1600 ° C).
Umutungo w'ingenzi kuriAlumina:
Ubushyuhe buhamye
Imbaraga nyinshi no gukomera
Inshinge z'amashanyarazi
Kurwanya cyane kwambara no guterana amagambo
Ubushobozi bwo kwihanganira ruswa kubushyuhe bwo hejuru
Umutungo w'ingenzi kuriMullite:
Imiterere n'ibigize
Aluminium oxide (al2o3)Hamwe ninzego zisumba kuva kuri 75% kugeza hejuru ya 99% nikintu nyamukuru gikoreshwa mugukora ceramics ya alumina. Gukomera no kwambara kwiyongera kwiyongera hamwe na alumina. Imiterere ya kirisiti itanga iherezo ryiza nimbaraga zubukanishi.
Ibikoresho bigizemullite ceramicsEse Aluminim Yaseli (3alo3·2SiO2). Mubisanzwe biremwa nubushyuhe bwinshi bwa Silica na Alumina, bitanga imiterere yoroshye hamwe numutekano wo mu bushyuhe buhebuje. Kwihangana kwa Mullite kugeza mu bushyuhe kandi bwo kwaguka ubushyuhe buke bituma bifite agaciro.
Umutungo
Alumina'Kurwanya Ibikuru bya Aburamu bituma bituma bituma bigabanya ibikoresho no kurengera.
Mullite'Ibiranga umutwe bidasanzwe n'imbaraga (6-7 Mohs Hardness) bikahitamo neza ku indege zunganira indege no guhinduranya imiti.
Imiterere ya mashini
Aluminaazwiho gukomera gukomeye, imbaraga zo kwikuramo cyane, hamwe no kurwanya cyane. Ibi biranga bituma habaho guhitamo neza kwambara imirongo, gusya itangazamakuru, hamwe nibisabwa byinshi aho Aburamu ahangayikishijwe cyane.
Mullitentabwo bikomeye kuruta alumina, nyamara itanga imbaraga zihagije zamashini mugihe nazo ziri munsi yuburemere. Imico yacyo ya mashini iringanizwa nubushobozi bwayo bwo kurwanya imihindagurikire yubushyuhe.
Ubushyuhe no kurwanya imiti
Alumina Ceramicsirashobora kunanira ubushyuhe bukabije bukabije mugihe usigaye muburyo bwo kwambara bikomeye. Barwanya kandi acide na alkalis, bituma batunganya ibihe bibinga.
MulliteCeramics ihagaze cyane cyane kuri Thermal irwanya ubushyuhe bworoshye hamwe nu muco muto. Bakora neza mumatami menshi yubushyuhe, imirongo ya kiln, hamwe nibisabwa byoroshye aho gusiganwa ku magare bibaye kenshi.
Gusaba:
Alumina'Amashanyarazi ahindura imico akwiye kuba akwiriye gusimburwa na elegitoroniki n'ibikoresho bitangaje. Kubera iyanjye zidasanzwe zo kurwanya, ubutwari bwa Alumina bukunze gukoreshwa mumipira yo gusya, bambara imipira, imiyoboro aho ubuzima bwa serivisi busabwa.
Mullite'Ubushyuhe bwo hejuru butuje ni ngombwa kugirango tunjize iminyago no mu ndege.
Kurangiza,Alumina CeramicsNibikoresho byatoranijwe kugirango bimbure hejuru kandi bihendutse byangiza imiti kubera gukomera kwinshi, kwambara kurwanya, no kwihangana imiti.Mullite ceramicsKu rundi ruhande, ufite ubushyuhe buhebuje no kwihangana ku buryo bwo guhindagura ubushyuhe bwihuse, bigatuma barushaho kuba iby'ikirere cyo hejuru.
