I-Aluminium oxide Crucible AL2O3 Crucible
isethulo somkhiqizo
I-Aluminium oxide crucible evame ukwaziwa ngokuthi i-corundum crucible, abantu ngokuvamile bazokuqukethwe kwe-alumina ku-crucible engaphezu kuka-95% ebizwa ngokuthi i-corundum crucible.I-Corundum crucible ukumelana nokuncibilika okuqinile, ukumelana nokushisa okuphezulu, ukumelana ne-asidi ne-alkali, ukumelana nokubanda nokushisa, ukumelana nokugqwala kwamakhemikhali.Ilungele ezinye izinto ezine-alkali ezibuthakathaka njenge-anhydrous Na2CO3 njengamasampula okuncibilika kwe-flux, kodwa hhayi i-Na2O2, i-NaOH, njll. Izinto eziqinile ze-alkaline nezinto ezine-asidi ezisetshenziswa njengamasampula okuncibilika kwe-flux... i-alumina crucible enobumsulwa obungu-99.70% inokushisa okuphezulu okuhle ukwahlukanisa namandla emishini endaweni ye-redox engu-1650℃ -1700℃, enezinga lokushisa eliphakeme elingu-1800℃ ngesikhathi esifushane.Ngokwemibandela yohlelo lokusebenza, ama-alumina crucibles atholakala ngobukhulu obuhlukahlukene kanye nokwakheka.
Izici Eziyinhloko
Izici Eziyinhloko ze-alumina ceramic crucible: ukumelana nokushisa okungaba amadigri ayi-1200, afanele i-K2S207 namanye amasampula okuncibilika kwe-asidi.Ngokuvamile, akufanele isetshenziselwe ukuncibilika kwe-Na0H, Na202 kanye ne-Na2CO3, ukuze ingagqwali i-porcelain crucible.I-porcelain crucible ayikwazi ukuxhumana ne-hydrofluoric acid.
I-alumina ceramic crucible ingabiliswa nge-HCl ukuqinisekisa ubumsulwa bezinto ezibonakalayo kanye nokumelana nokushisa okuphezulu.Indaba inokuminyana okuphezulu, ukumelana okuhle kwe-oxidation, ama-degree angama-400-500 aphakeme kune-graphite material, afinyelela ku-900 degrees ephakeme, impilo ende yesevisi.Ngokumelana nokushisa okuphezulu, i-coefficient ephansi yokwandisa okushisayo, ukushisa okuhle nokumelana nokushaqeka nokumelana nokugqwala okuhle.Ukusebenza kwamakhemikhali kuzinzile futhi ngokuyisisekelo akusabeli ngensimbi encibilikisiwe, ukuthuthukisa ukuhlanzeka kwe-alloy.
(1) Kulula ukuwasha nokugcina kuhlanzekile.I-glaze ye-ceramic crucible ikhanya futhi ithambile, futhi kulula ukuyigeza ngemuva kokusetshenziswa.
(2) I-porcelain stoma incane kakhulu, futhi izinga lokumuncwa kwamanzi liphansi kakhulu.Ukugcinwa kwesisombululo nge-ceramic crucible kanye nokuvala uphawu okuqinile kungavimbela ukuvuthwa, ukungena kanye nokuhlasela kwamagciwane angaphandle.
(3) Ukuzinza kwamakhemikhali nokuqina.Leli phuzu liphakeme kunemikhiqizo yensimbi efana nethusi, insimbi, i-aluminium, njll., i-ceramic crucible inokumelana okuthile ne-asidi, i-alkali, usawoti kanye nokuguguleka kwegesi ye-carbonate emkhathini, akulula ukuba nokusabela kwamakhemikhali ngalezi zinto, hhayi ukugqwala. ukuguga.
(4) Ukuzinza okuhle kokushisa nokudlulisa ukushisa kancane.I-Ceramic crucible inokusebenza kokuya kumehluko othile wokushisa, okungcono kune-glassware, i-conductor embi yokushisa, ukudlulisa ukushisa okuhamba kancane, okusetshenziselwa ukubamba amanzi abilayo noma isisombululo esishisayo, ukuphela akushisi kakhulu.
Isicelo somkhiqizo
I-Alumina isetshenziswa kabanzi kakhulu, i-electronics, i-petroleum, ikhemikhali, i-refractory, i-ceramics, ipulasitiki, izindwangu, iphepha, kanye nemithi kanye neminye imikhakha eminingi ingabonakala isibalo sayo, ngokuvamile siyizakhiwo ezikhethekile ze-alumina ne-aluminium hydroxide.Kodwa-ke, ngaphezu kwamaphesenti angama-90 we-alumina isetshenziswa njengempahla eluhlaza ye-aluminium electrolytic.
Njengamanje, kunezinhlobo eziningi ze-non-alumina zokwelapha, izinhlobo ezingaphezu kuka-300, ngayinye enezakhiwo ezinhle kakhulu zomzimba namakhemikhali, kodwa intengo iphakeme kakhulu kune-alumina yokwelashwa.
Ekuhlanzekeni okuphezulu kwe-ultrafine alumina, isibonelo, ngenxa yezinga eliphezulu lokuncibilika, ukuqina okuphezulu, ukumelana okuphezulu, izakhiwo ezinhle zemishini, ukumelana nokugqoka, ukumelana nokugqwala, ukumelana nokushisa nezinye izici ezinhle kakhulu ze-2.Main, ngakho-ke isetshenziswa kabanzi ezintweni ze-crystal eyodwa. , i-porcelain ethuthukisiwe, ithambo lokwenziwa, i-semiconductor, izinto zokugaya, i-substrate yesifunda ehlanganisiwe, i-tape filler yokurekhoda, i-catalyst kanye nenkampani yayo yenethiwekhi, izinto ze-laser, amathuluzi okusika, njll.
