Amatafari asanzwe arwanya ubukana:Iyo urebye igiciro gusa, ushobora guhitamo amatafari asanzwe ahendutse, nk'amatafari y'ibumba. Iri tafari rirahendutse. Itafari rigura gusa $0.5 ~ 0.7 ku ikarito. Rifite uburyo bwinshi bwo kurikoresha. Ariko se, rikwiriye gukoreshwa? Ku bijyanye n'ibisabwa, iyo ritubahirijwe, rishobora gutera isuku kenshi bitewe no kwangirika no gucika, kandi rishobora kutabasha gukoreshwa uko bisanzwe. Gusubiramo ibikorwa bishobora gutuma ibikoresho bivugururwa hakiri kare ndetse bikangirika, ibyo bikaba bitakwiriye inyungu.
Amatafari y'ibumba ni ibikoresho bifite aside nkeya, bifite ubucucike bw'umubiri bwa 2.15g/cm3 n'ingano ya alumina ya ≤45%. Nubwo ubushobozi bwo kutarenza urugero buri hejuru ya 1670-1750C, ahanini ikoreshwa mu bushyuhe buri hejuru ya 1400C. Iki gicuruzwa gishobora gukoreshwa gusa mu gihe cyujuje ibisabwa. Ubushyuhe, bimwe mu bice bidakenewe, imbaraga zisanzwe zo gukanda amatafari y'ibumba ntabwo ari hejuru, ni 15-30MPa gusa, ibi bifitanye isano n'ibipimo by'ibicuruzwa, ari nayo mpamvu amatafari y'ibumba ahendutse.
Amatafari menshi ya alumina arwanya ibidukikije:Amatafari ya alumina menshi afite ibyiciro bine bishingiye kuri alumina. Kubera ko ingano ya alumina iri mu bikoresho fatizo iri hejuru y’amatafari y’ibumba, izina ry’amatafari ya alumina menshi rikomoka kuri ibi. Dukurikije ingano, iki gicuruzwa gishobora gukoreshwa mu bushyuhe buri hagati ya 1420 na 1550°C. Iyo gikoreshejwe, gishobora gushyirwa mu muriro. Ingufu zisanzwe zo gukanda ubushyuhe ni 50-80MPa. Iyo gishyizwe mu muriro, ubushyuhe bwo hejuru ntibushobora kuba hejuru y’ubushyuhe bwo gukora. Ibi bikunze kugirwaho ingaruka n’ubucucike bw’igicuruzwa n’ingano ya alumina.
Amatafari menshi:Amatafari ya Mullite arwanya ubushyuhe bwinshi n'ubushyuhe bwinshi bwo gukora. Aboneka mu bwoko buremereye n'ubworoheje. Amatafari ya Mullite akomeye arimo amatafari ya Mullite avanze n'amatafari ya Mullite akozwe mu buryo bwa sintered. Ubudahangarwa bw'ubushyuhe bw'icyo gicuruzwa ni bwiza; ibikoresho byoroheje bifite ubushobozi bwiza bwo gukingira ubushyuhe. Ibikoresho byoroheje ni: JM23, JM25, JM26, JM27, JM28, JM30, JM32. Ibikoresho bya Mullite byoroheje bishobora gushyirwa ku muriro, kandi imyenge ikwirakwizwa ku buryo bungana. Dukurikije uburemere bwihariye n'ingano y'ibikoresho fatizo by'icyo gicuruzwa, JM23 ishobora gukoreshwa munsi ya dogere 1260, JM26 munsi ya dogere 1350, na JM30 ishobora gukoreshwa mu bushyuhe bwinshi bwa dogere 1650. Iyi ni nayo mpamvu amatafari ya Mullite ahenze.
Itafari rya Corundum:Amatafari ya Corundum ni amatafari yo mu rwego rwo hejuru arwanya ubushyuhe afite ingano irenga 90%. Iki gicuruzwa gifite kandi ibikoresho byasinze kandi bivanze. Dukurikije ibikoresho fatizo, ibi bicuruzwa birimo: amatafari ya zirconium corundum (AZS, amatafari ya fused cast), amatafari ya chromium corundum, nibindi. Ubushyuhe busanzwe burengeje 100MPa kandi bushobora gukoreshwa igihe kirekire mu bushyuhe bwinshi bwa dogere 1,700. Igiciro cy'aya matafari arwanya ubushyuhe kiratandukanye kuva ku bihumbi byinshi kugeza ku bihumbi icumi bya yuan kuri toni bitewe n'ibintu nk'uburyo ikorwa n'ingano y'ibikoresho fatizo.
Amatafari y'umupira w'alumina afite ubugari:Amatafari y’umuhondo wa alumina ni amatafari ahenze cyane yoroshya ubushyuhe, agura hafi RMB 10.000 kuri toni. Bitewe n’ahantu hatandukanye ho gukoreshwa n’uburyo bwo kuyatunganya, harimo n’ingano ya alumina, n’ibindi, igiciro cy’umusaruro kigomba kuba kiri hejuru. , nk’uko bivugwa, agaciro k’amafaranga.
Ibi byavuzwe haruguru ni intangiriro y'ubucucike, ubushyuhe bwinshi n'igiciro cy'amatafari arwanya ubushyuhe. Muri rusange, ubucucike bw'ibikoresho birwanya ubucucike bupimwa mbere yo kuva mu ruganda. Ubucucike bw'ingano: bugaragaza ikigereranyo cy'uburemere bw'ibicuruzwa byumye n'ingano yabyo yose, bigaragazwa muri g/cm3.
