I-Crucible ne-Sagger

I-crucible iyimbiza ye-ceramic esetshenziselwa ukubamba insimbi ukuze incibilikiswe esithandweni. Lena i-crucible yekhwalithi ephezulu, yezinga lezimboni esetshenziswa imboni yezingcezu zezentengiselwano.

Kudingeka i-crucible ukuze imelane namazinga okushisa aphezulu atholakala ezinsimbini ezincibilikayo. Izinto ezincibilikayo kumele zibe nephuzu lokuncibilika eliphakeme kakhulu kunelensimbi encibilikayo futhi kumele zibe namandla amahle ngisho noma zishisa kakhulu.

I-silicon carbide crucible eshisa kakhulu iyifenisha efanelekile ye-oven yezitofu zezimboni, efanelekile ukushiswa nokuncibilikiswa kwemikhiqizo ehlukahlukene, futhi isetshenziswa kabanzi kumakhemikhali, uphethiloli, ukuvikelwa kwemvelo kanye neminye imikhakha. I-silicon carbide iyisakhi samakhemikhali esiyinhloko se-silicon carbide germanium, enezici zobulukhuni obuphezulu. Ubulukhuni be-silicon carbide crucible buphakathi kwe-corundum nedayimane, amandla ayo okusebenza aphezulu kune-corundum, ngesilinganiso sokudlulisa ukushisa esiphezulu, ngakho-ke ingonga amandla amaningi.

I-RBSiC/SISIC crucible kanye ne-sagger iyisitsha se-ceramic esijulile. Ngenxa yokuthi ingcono kunezitsha zeglasi maqondana nokumelana nokushisa, isetshenziswa kahle lapho okuqinile kushiswa ngumlilo. I-Sagger ingenye yefenisha ye-oven ebalulekile yokushisa i-porcelain. Zonke izinhlobo ze-porcelain kumele zifakwe kuma-saggers kuqala bese zifakwa ku-oven ukuze ziyosiwe.

I-silicon carbide melting crucible iyizingxenye eziyinhloko zamathuluzi amakhemikhali, iyisitsha esisodwa esingasetshenziswa ukuncibilikisa, ukuhlanza, ukufudumeza kanye nokusabela. Kufakwe amamodeli nosayizi abaningi; akukho mkhawulo ekukhiqizweni, ubuningi noma izinto zokwakha.

I-Silicon carbide melting crucible iyizitsha ze-ceramic ezimise okwesitsha esijulile ezisetshenziswa kabanzi embonini yensimbi. Uma izinto eziqinile zishiswa ngomlilo omkhulu, kumele kube nesitsha esifanele. Kuyadingeka ukusebenzisa i-crucible ngenkathi ufudumeza ngoba ingamelana nokushisa okuphezulu kunezitsha zengilazi futhi iqinisekise ubumsulwa ekungcoleni. I-silicon carbide melting crucible ayikwazi ukugcwaliswa kakhulu okuqukethwe okuncibilikisiwe ngoba izinto ezishisayo zingabiliswa bese zifafazwa. Ngaphandle kwalokho, kubalulekile futhi ukugcina umoya ujikeleza ngokukhululeka ukuze kube nokusabela kwe-oxidation okungenzeka.

Isaziso:
1. Yigcine yomile futhi ihlanzekile. Kudingeka ifudunyezwe ku-500℃ kancane ngaphambi kokusebenzisa. Gcina zonke izitsha eziphekiwe endaweni eyomile. Umswakama ungabangela ukuthi isitsha esiphekiwe siqhekeke lapho sifudunyezwa. Uma sesigcinwe isikhathi eside kungcono ukuphinda ukufudumala. Izitsha eziphekiwe ze-silicon carbide ziyindlela engenakwenzeka kakhulu yokumunca amanzi lapho zigcinwa futhi ngokuvamile azidingi ukufudunyezwa ngaphambi kokusetshenziswa. Kungumqondo omuhle ukuthulula isitsha esiphekiwe esisha sibe bomvu ngaphambi kokusetshenziswa kwaso kokuqala ukuze sishaye futhi siqinise izimbozo zasefektri kanye nezihlanganisi.
2. Beka izinto ezisetshenziswayo ku-silicon carbide melting crucible ngokwevolumu yayo bese ugcina isikhala esifanele ukugwema ukuqhekeka kokushisa. Izinto kufanele zifakwe ku-crucible kalula. UNGALOKOTHI “upakishe” i-crucible, njengoba izinto ezisetshenziswayo zizokhula ekushiseni futhi zingaphula i-ceramic. Uma le nto isincibilikile ibe “isithende”, faka ngokucophelela izinto ezengeziwe echibini ukuze zincibilike. (ISEXWAYISO: Uma kukhona umswakama ezintweni ezintsha kuzovela UKUQHUBEKA komusi). Futhi, ungapakishi insimbi ngokuqinile. Qhubeka ufaka izinto ezisetshenziswayo ku-melting kuze kube yilapho inani elidingekayo selincibilikile.
3. Zonke izitsha zokubopha kufanele ziphathwe ngezitsha zokubopha ezifanele (ithuluzi lokuphakamisa). Izitsha zokubopha ezingafanele zingabangela umonakalo noma ukwehluleka ngokuphelele kwesitsha sokubopha ngesikhathi esibi kakhulu.
4. Gwema umlilo onamandla oshisiwe ovuthayo ngqo esitsheni sokushiswa. Kuzofinyeza isikhathi sokusebenzisa ngenxa yokushiswa kwezinto ezibonakalayo.
5. Ungabeki i-silicon carbide eshisayo encibilikayo ensimbi ebandayo noma endaweni yokhuni ngokushesha. Ukubanda okungazelelwe kuzoholela ekuqhekekeni noma ekuqhekekeni futhi indawo yokhuni ingabangela umlilo. Sicela uyishiye esitini noma epuletini eliqinile bese uyivumela ukuthi iphole ngokwemvelo.
