I-Crucible ne-Sagger

I-crucible ibhodwe le-ceramic elisetshenziswa ukubamba insimbi ukuze inyibilike esithandweni. Lesi yikhwalithi ephezulu, i-crucible yebanga lezimboni esetshenziswa imboni yezohwebo.

I-crucible iyadingeka ukuze imelane namazinga okushisa adlulele okuhlangatshezwana nawo ekuncibilikeni kwezinsimbi. I-crucible material kufanele ibe nendawo yokuncibilika ephakeme kakhulu kunaleyo yensimbi encibilikayo futhi kufanele ibe namandla amahle ngisho nalapho kushisa okumhlophe.

I-high-temperature silicon carbide crucible iyifenisha efanelekile yeziko lezimboni, ifanele ukushiswa nokuncibilikiswa kwemikhiqizo ehlukahlukene, futhi isetshenziswa kabanzi kumakhemikhali, uphethiloli, ukuvikelwa kwemvelo neminye imikhakha. I-Silicon carbide iyingxenye yamakhemikhali eyinhloko ye-silicon carbide germanium, enezici zokuqina okuphezulu. Ukuqina kwe-silicon carbide crucible kuphakathi kwe-corundum nedayimane, amandla ayo omshini aphakeme kune-corundum, enezinga eliphezulu lokudlulisa ukushisa, ngakho-ke ingonga amandla amaningi.

I-RBSiC/SISIC crucible kanye ne-sagger iyisitsha esijulile se-ceramic. Ngenxa yokuthi iphakeme kune-glassware mayelana nokumelana nokushisa, isetshenziswa kahle lapho okuqinile kushiswa ngomlilo. I-Sagger ingenye yefenisha yomlilo ebalulekile yokushisa i-porcelain. Zonke izinhlobo ze-porcelain kufanele zifakwe ku-saggers kuqala bese zifakwa kuhhavini ukuze ziyosiwe.

I-silicon carbide melting crucible yizingxenye eziyinhloko zamathuluzi amakhemikhali, iyisitsha esisodwa esingasetshenziselwa ukuncibilika, ukuhlanzwa, ukushisa nokusabela. Amamodeli amaningi namasayizi afakiwe; awukho umkhawulo ovela ekukhiqizeni, ubuningi noma izinto zokwakha.

I-Silicon carbide melting crucible iyisitsha esijulile somumo wesitsha se-ceramic esisetshenziswa kakhulu embonini ye-metallurgy. Lapho okuqinile kushiswa umlilo omkhulu, kufanele kube nesiqukathi esifanele. Kudingekile ukusebenzisa i-crucible ngenkathi ushisa ngoba ingakwazi ukumelana nezinga lokushisa eliphakeme kune-glassware futhi iphinde iqinisekise ukuhlanzeka ekungcoleni. I-silicon carbide melting crucible ayikwazi ukugcwaliswa ngokweqile okuqukethwe okuncibilikisiwe kubangele ukuthi izinto ezishisiwe zingabiliswa futhi zifafazwe. Uma kungenjalo, kubalulekile futhi ukugcina umoya uzungeza ngokukhululekile ukuze uthole ukusabela okungenzeka kwe-oxidation.

Isaziso:
1. Yigcine yomile futhi ihlanzekile. Kudingeka ukushisisa ku-500 ℃ kancane ngaphambi kokusebenzisa. Gcina zonke izitsha endaweni eyomile. Umswakama ungabangela ukuthi i-crucible iqhekeke ekushiseni. Uma igcinwe isikhathi eside kungcono ukuphinda ukufutheka. I-silicon carbide crucibles iwuhlobo oluncane okungenzeka lumunce amanzi endaweni yokugcina futhi ngokuvamile ayidingi ukuthukutheliswa ngaphambi kokusetshenziswa. Kungumbono omuhle ukushisa i-crucible entsha ekushiseni okubomvu ngaphambi kokusetshenziswa kwayo kokuqala ukushayela futhi uqinise ama-coatings asefekthri nezibophezelo.
2. Beka izinto ku-silicon carbide encibilika i-crucible ngokusho kwevolumu yayo futhi ugcine isikhala esifanele ukuze ugweme ukuhlukana kokwanda okushisayo. Impahla kufanele ifakwe ku-crucible ngokukhululeka KAKHULU. UNGALOKOTHI "upakishe" i-crucible, njengoba impahla izokhula ekushiseni futhi ingaqhekeka i-ceramic. Uma le nto isincibilikile ibe "isithende", layisha ngokucophelela izinto eziningi emgodleni ukuze zincibilike. (ISEXWAYISO: Uma YILUPHI umswakama okhona kwinto entsha kuzovela UKUPHUMULA kwesitimu). Nalapha futhi, musa ukupakisha ngokuqinile ensimbi. Qhubeka uphakela uketshezi ekuncibilikeni kuze kube yilapho inani elidingekayo selincibilikile.
3. Zonke izinsimbi kufanele ziphathwe ngodlawu olulingana kahle (ithuluzi lokuphakamisa). Ama-tongs angalungile angabangela umonakalo noma ukwehluleka okuphelele kwe-crucible ngesikhathi esibi kakhulu.
4. Gwema umlilo onamandla oksijini ovutha ngqo ku-crucible. Izonciphisa isikhathi sokusebenzisa ngenxa ye-oxidation yezinto ezibonakalayo.
5. Ungabeki i-silicon carbide encibilikayo crucible phezu kwensimbi ebandayo noma endaweni yokhuni ngokushesha. Umkhuhlane ongazelelwe uzoholela ekuqhekekeni noma ekuqhekekeni futhi indawo yokhuni ingabangela umlilo. Sicela uyishiye esitini esiphikisayo noma epuletini futhi uyiyeke iphole ngokwemvelo.
