I-Crucible kunye ne-Sagger

I-crucible yimbiza ye-ceramic esetyenziselwa ukubamba isinyithi sokunyibilika kwiziko. Lo ngumgangatho ophezulu, ibakala lemveliso elisetyenziswa lishishini elisisiseko sorhwebo.

I-crucible iyafuneka ukumelana namaqondo obushushu agqithisileyo afunyenwe kwiintsimbi ezinyibilikayo. Izinto ezicholwayo kufuneka zibe nenqanaba eliphezulu lokunyibilika kunelo lentsimbi enyibilikayo kwaye kufuneka libe namandla alungileyo naxa kushushu kumhlophe.

Ubushushu obuphezulu be-silicon carbide crucible yifenitshala ye-kiln efanelekileyo yeziko lamashishini, ilungele ukuntywila kunye nokunyibilikiswa kweemveliso ezahlukeneyo, kwaye isetyenziswa kakhulu kwimichiza, i-petroleum, ukhuseleko lokusingqongileyo kunye namanye amacandelo. I-silicon carbide iyona nxalenye yeekhemikhali eziphambili ze-silicon carbide germanium, eneempawu eziphezulu zobunzima. Ubunzima be-silicon carbide crucible buphakathi kwe-corundum kunye nedayimane, amandla ayo omatshini angaphezulu kwe-corundum, enezinga eliphezulu lokudlulisa ukushisa, ngoko inokugcina amandla amaninzi.

I-RBSiC / SISIC i-crucible kunye ne-sagger yisitya esinzulu se-ceramic. Ngenxa yokuba iphezulu kwi-glassware malunga nokumelana nokushisa, isetyenziswe kakuhle xa i-solid itshiswa ngumlilo. I-Sagger yenye yefenitshala ye-kiln ebalulekileyo yokutshisa i-porcelain. Zonke iintlobo zeporcelain kufuneka zifakwe kwi-saggers kuqala kwaye emva koko zifakwe kwi-oven ukuze zigcadwe.

I-silicon carbide i-melting crucible iyona nxalenye eziphambili zezixhobo zeekhemikhali, yisitya esinye esingasetyenziselwa ukunyibilika, ukucocwa, ukufudumeza kunye nokuphendula. Iimodeli ezininzi kunye nobukhulu zibandakanyiwe; akukho mda kwimveliso, ubuninzi okanye izinto.

I-silicon carbide melting crucible sisitya esinzulu sesitya se-ceramic esisetyenziswa kakhulu kwishishini lesinyithi. Xa izinto eziqinileyo zitshiswa ngumlilo omkhulu, kufuneka kubekho isikhongozeli esifanelekileyo. Kuyimfuneko ukusebenzisa i-crucible ngelixa ufudumeza kuba inokumelana nokushisa okuphezulu kune-glassware kwaye iqinisekise ukucoceka kokungcola. I-silicon carbide crucible melting crucible ayinakuzaliswa ngokugqithisileyo yimixholo etyhidiweyo ibangela ukuba izinto ezifudumeleyo zibiliswe kwaye zitshizwe ngaphandle. Ngaphandle koko, kukwabalulekile ukugcina umoya ujikeleza ngokukhululekileyo ukwenzela ukusabela okunokwenzeka kwe-oxidation.

Isaziso:
1. Yigcine yomile kwaye icocekile. Kufuneka ifudunyezwe ukuya kutsho kuma-500℃ kancinane phambi kokuba uyisebenzise. Gcina zonke ii-crucibles kwindawo eyomileyo. Ubumanzi bunokubangela ukuba i-crucible iqhekeke ekufudumeni. Ukuba igcinwe ixesha elide, kungcono ukuphinda ubushushu. I-silicon carbide crucibles lolona hlobo luncinci lokufunxa amanzi kwindawo yogcino kwaye aludingi kucutshungulwa phambi kokusetyenziswa. Kungumbono olungileyo ukutshisa i-crucible entsha kubushushu obubomvu ngaphambi kokusetyenziswa kwayo kokuqala ukuqhubela phambili kunye nokuqinisa iingubo zefektri kunye nezibophelelo.
2. Beka izinto kwi-silicon carbide melting crucible ngokomthamo wayo kwaye ugcine indawo efanelekileyo yokuphepha ukuphuka kwe-thermal ukwanda. Izinto eziphathekayo kufuneka zifakwe kwi-crucible KAKHULU ngokukhululekileyo. UNGAZE "upakishe" i-crucible, njengoko izinto eziphathekayo ziya kwandiswa ekufudumeni kwaye zikwazi ukuqhekeza i-ceramic. Emva kokuba le nto inyibilikile "kwisithende", layisha ngokucophelela izinto ezininzi kwi-puddle yokunyibilika. (ISILUMKISO: Ukuba KUKHO NAKUPHI ukufuma kwimathiriyeli entsha kuya kubakho UKUPHUPHUMA komphunga). Kwakhona, musa ukupakisha ngokuqinileyo kwintsimbi. Gcina ukondla izinto eziphathekayo kwi-melted de ubuninzi obufunekayo buncibilike.
3. Zonke ii-crucibles kufuneka ziphathwe ngeetongs ezifanelekileyo (isixhobo sokuphakamisa). I-tongs engafanelekanga inokubangela umonakalo okanye ukungaphumeleli ngokupheleleyo kwe-crucible ngexesha elibi kakhulu.
4. Gwema umlilo oqinileyo oxidized ovuthayo ngokuthe ngqo kwi-crucible. Iya kunciphisa ixesha lokusebenzisa ngenxa ye-oxidation yezinto eziphathekayo.
5. Musa ukubeka i-silicon carbide crucible enyibilikayo kwintsimbi ebandayo okanye kwindawo yokhuni ngokukhawuleza. Ingqele yesiquphe ikhokelela kwiintanda okanye ukwaphuka kwaye umphezulu weplanga unokubangela umlilo. Nceda uyishiye kwisitena esichasayo okanye kwipleyiti kwaye uyiyeke iphole ngokwemvelo.
