Amatafari asanzwe yangiritse:Niba ureba gusa igiciro, urashobora guhitamo amatafari asanzwe ahendutse, nk'amatafari y'ibumba. Amatafari ahendutse. Amatafari agura amadorari 0.5 ~ 0.7 / guhagarika. Ifite uburyo butandukanye bwo gukoresha. Ariko, birakwiriye gukoreshwa? Kubijyanye nibisabwa, niba bitujujwe, birashobora gutera kubungabunga kenshi kubera kwambara no kurira, kandi ntibishobora gukoreshwa mubisanzwe. Kubungabunga inshuro nyinshi birashobora gutuma hakosorwa hakiri kare ndetse bikangirika no kwangiza ibikoresho, bidakwiye inyungu.
Amatafari y'ibumba ni ibikoresho bya acide nkeya, hamwe nubucucike bwumubiri bugera kuri 2.15g / cm3 hamwe na alumina irimo ≤ 45%. Nubwo kuvunika ari hejuru ya 1670-1750C, ikoreshwa cyane mubushyuhe bwo hejuru bwa 1400C. Iki gicuruzwa gishobora gukoreshwa gusa hubahirijwe ibisabwa. Ubushyuhe, ibice bimwe bidafite akamaro, imbaraga zisanzwe zo gukanda imbaraga zamatafari yibumba ntabwo ari hejuru, 15-30MPa gusa, ibi bifitanye isano nibipimo byibicuruzwa, ari nayo mpamvu ituma amatafari yibumba ahendutse.
Amatafari maremare ya alumina:Amatafari maremare ya alumina afite amanota ane ashingiye kuri alumina. Kuberako aluminiyumu yibikoresho bibisi iruta iy'amatafari y'ibumba, izina amatafari maremare ya alumina akomoka aha. Ukurikije icyiciro, iki gicuruzwa gishobora gukoreshwa mubushyuhe bwo hejuru bwa 1420 kugeza 1550 ° C. Iyo ikoreshejwe, irashobora guhura numuriro. Ubushyuhe busanzwe bwo guhonyora ni hejuru ya 50-80MPa. Iyo uhuye numuriro, ubushyuhe bwubuso ntibushobora kuba hejuru yubushyuhe bwo gukora. Ibi byibasiwe cyane nubucucike bwibicuruzwa nibirimo alumina.
Amatafari ya mullite:Amatafari ya mullite yamashanyarazi afite ubukana bwinshi nubushyuhe bwo hejuru. Baraboneka muburyo buremereye kandi bworoshye. Amatafari mullite aremereye arimo amatafari ya mullite hamwe n'amatafari ya mullite. Ibicuruzwa bya Thermal shock resistance nibyiza; ibicuruzwa byoroheje bifite ingaruka nziza zo kubika ubushyuhe. Ibicuruzwa byoroheje ni: JM23, JM25, JM26, JM27, JM28, JM30, JM32. Ibicuruzwa byoroheje bya mullite birashobora guhura n’umuriro, kandi imyenge igabanywa neza Ukurikije uburemere bwihariye n’ibikoresho fatizo byibicuruzwa, JM23 irashobora gukoreshwa munsi ya dogere 1260, JM26 munsi ya dogere 1350, na JM30 irashobora gukoreshwa muri ubushyuhe buri hejuru ya dogere 1650. Ninimpamvu ituma amatafari ya mullite ahenze.
Amatafari ya Corundum:Amatafari ya Corundum ni amatafari yo mu rwego rwohejuru yamatafari afite alumina irenga 90%. Iki gicuruzwa nacyo cyacumuye kandi gihuza ibicuruzwa. Ukurikije ibikoresho fatizo, ibicuruzwa birimo: amatafari ya zirconium corundum yahujwe (AZS, amatafari yometseho amatafari), amatafari ya chromium corundum, nibindi. ya dogere 1.700. Igiciro cyaya matafari yangiritse kiratandukanye kuva ku bihumbi byinshi kugeza ku bihumbi icumi byamafaranga kuri toni bitewe nimpamvu nkibikorwa byo kubyaza umusaruro nibirimo ibikoresho fatizo.
Amatafari ya Alumina yubusa:Amatafari ya Alumina yuzuye amatafari ahenze cyane kubumba amatafari yoroheje, atwara amafaranga agera ku 10,000. Bitewe no gukoresha ibidukikije bitandukanye nibikorwa byumusaruro, harimo ibirimo alumina, nibindi, igiciro cyibicuruzwa kigomba kuba kinini. , nkuko bivugwa, agaciro kumafaranga.
Ibyavuzwe haruguru ni intangiriro yubucucike, ubushyuhe bwo hejuru hamwe nigiciro cyamatafari yangiritse. Mubisanzwe, ubwinshi bwibikoresho byangiritse bipimwa mbere yo kuva muruganda. Ubucucike bwijwi: bwerekana igipimo cyubwinshi bwibicuruzwa byumye nubunini bwacyo, bigaragarira muri g / cm3.
