I-Aluminiyam i-Oxide I-Crucible AL2O3 I-Crucible
umboniso wemveliso
I-Aluminium oxide crucible eyaziwa ngokuba yi-corundum crucible, abantu ngokuqhelekileyo baya kumxholo we-alumina ngaphezu kwe-95% ye-crucible ebizwa ngokuba yi-corundum crucible.I-Corundum crucible inamandla okumelana nokunyibilika, ukumelana nobushushu obuphezulu, ukuxhathisa kwe-asidi kunye ne-alkali, ukumelana nokubanda kunye nobushushu, ukuxhathisa ukubola kweekhemikhali.Ifanelekile kwezinye izinto ezibuthathaka ze-alkaline ezifana ne-anhydrous Na2CO3 njengeesampuli zokunyibilika kwe-flux, kodwa kungekhona i-Na2O2, i-NaOH, njl. ukugquma kunye namandla omatshini kwi-redox umoya we-1650 ℃ -1700 ℃, kunye nobushushu obuninzi be-1800 ℃ ngexesha elifutshane.Ngokweemeko zesicelo, ii-alumina crucibles zifumaneka ngobukhulu obuhlukeneyo kunye nemilo.
Iimpawu eziphambili
Iimpawu eziphambili ze-alumina ceramic crucible: ukumelana nobushushu malunga ne-1200 degrees, ilungele i-K2S207 kunye nezinye iisampuli ze-asidi ezinyibilikayo.Ngokuqhelekileyo, akufanele isetyenziselwe ukunyibilika kwe-Na0H, i-Na202 kunye ne-Na2CO3, ukuze ingadli i-porcelain crucible.I-porcelain crucible ayikwazi ukudibanisa ne-hydrofluoric acid.
I-alumina ceramic crucible inokubiliswa nge-HCl ukuqinisekisa ukucoceka kwezinto kunye nokumelana nokushisa okuphezulu.Izinto eziphathekayo zinokuxinwa okuphezulu, ukuxhathisa okulungileyo kwe-oxidation, i-400-500 degrees ephezulu kune-graphite material, ukuya kuma-900 degrees aphezulu, ubomi benkonzo ende.Ngokumelana nobushushu obuphezulu, i-coefficient ephantsi yokwandiswa kwe-thermal, ubushushu obuhle kunye nokuxhathisa ukothuka kunye nokuxhathisa okulungileyo kokuhlwa.Ukusebenza kweekhemikhali kuzinzile kwaye ngokusisiseko akwenzi ngesinyithi esinyibilikisiweyo, ukuphucula ukucoceka kwe-alloy.
(1) Kulula ukuyihlamba nokuyigcina icocekile.I-glaze ye-ceramic crucible ikhanya kwaye ithambile, kwaye kulula ukuyihlamba emva kokusetyenziswa.
(2) I-porcelain stoma imbalwa kakhulu, kwaye nesantya sokufunxa kwamanzi siphantsi kakhulu.Ukugcinwa kwesisombululo kunye ne-ceramic crucible kunye nokutywinwa okungqongqo kunokuthintela ukuguquka, ukungena kunye nokuhlaselwa kweebhaktheriya zangaphandle.
(3) Ukuzinza kweekhemikhali kunye nokuqina.Eli nqaku liphezulu kwiimveliso zetsimbi ezifana nobhedu, isinyithi, i-aluminium, njl., i-ceramic crucible inokumelana okuthile ne-asidi, i-alkali, ityuwa kunye nokhukuliseko lwegesi ye-carbonate emoyeni, akukho lula ukusabela kweekhemikhali ngezi zinto, kungekhona umhlwa. ukwaluphala.
(4) Uzinzo oluhle lwe-thermal kunye nokudluliselwa kobushushu obucothayo.I-Ceramic crucible inomsebenzi wokuya kumlinganiselo othile weqondo lokushisa, ongcono kune-glassware, i-conductor embi yokushisa, ukuhanjiswa kobushushu obucothayo, esetyenziselwa ukubamba amanzi abilayo okanye isisombululo esishushu, isiphelo asishushu kakhulu.
Isicelo seMveliso
I-alumina isetyenziswa kakhulu, i-electronics, i-petroleum, ikhemikhali, i-refractory, i-ceramics, i-plastiki, i-textile, iphepha, i-pharmaceutical kunye nezinye iindawo ezininzi zinokubonwa umzobo wayo, ngokubanzi ziipropati ezikhethekileyo ze-alumina kunye ne-aluminium hydroxide.Nangona kunjalo, ngaphezu kwe-90 yepesenti ye-alumina isetyenziswa njengento ekrwada ye-aluminiyam ye-electrolytic.
Okwangoku, kukho iintlobo ezininzi ze-non-alumina zonyango, iintlobo ezingaphezu kwama-300, nganye yazo ineempawu ezibalaseleyo zomzimba kunye nemichiza, kodwa ixabiso liphezulu kakhulu kune-alumina yonyango.
Ekucocekeni okuphezulu kwe-alumina ye-ultrafine, umzekelo, ngenxa yeqondo eliphezulu lokunyibilika, ubunzima obuphezulu, ukuxhathisa okuphezulu, iipropati ezilungileyo ze-mechanical, ukumelana nokunxiba, ukuxhathisa ukubola, ukumelana nobushushu kunye nezinye iimpawu ezibalaseleyo ze-2.Main, ngoko isetyenziswa ngokubanzi kwizinto zekristale enye , i-porcelain ephezulu, ithambo lokufakelwa, i-semiconductor, izinto zokugaya, i-substrate yesiphaluka edibeneyo, i-tape filler yokurekhoda, i-catalyst kunye nomphathi wayo, izinto ze-laser, izixhobo zokusika, njl.
