I-graphite crucibleszisetshenziswa kabanzi ezinhlelweni ezahlukahlukene, futhi kubalulekile ukuhlola ngokucophelela bese ukhetha ngokucophelela izinto ezifanele. Nansi eminye imihlahlandlela yokuhlola nokukhethaama-graphite crucibles:
Ngaphambi kokusebenzisa Ukuhlola: Ngaphambi kokusebenzisa i-i-graphite crucible, hlola imifantu kanye nomonakalo. Ngokuqinisekile ayikho imifantu ebonakalayo, kuyadingeka ukushisa i-crucible ezingeni lokushisa elingaphezu kuka-600 ° C ukuze uqinisekise ukoma ngokuphelele.
Ukulungiswa Kwendawo: Qinisekisa ukuthi awekho amanzi aqoqiwe esithandweni noma emgodini lapho kuzobekwa khona i-crucible. Futhi, gcina izinto ezingahlobene kude eduze kwe-graphite crucible.
Ukuphatha Impahla: Thatha izinyathelo zokuphepha lapho uphatha izinto zesithando somlilo. Qinisekisa ukuthi izinto aziqhumi futhi zishisiwe futhi zomiswa kahle. Uma ungeza izinto ku-graphite crucible, kwenze kancane futhi kancane.
Kubalulekile ukulandela lezi ziqondiso zokuhlola ukuvimbela izingozi ezingase zibe khona nokuqhuma lapho usebenzisa izinsimbi ze-graphite.
I-graphite crucibles isetshenziselwa ngokuyinhloko ukushisa izinto zokuhlola. Zinobukhulu obuhlukahlukene nezinhlobo, okuvumela ukukhethwa kwe-crucible efanele ngokusekelwe enanini, uhlobo, nokunwetshwa okushisayo kwezinto ezishiswayo. Kubalulekile ukugwema ukugcwalisa i-crucible ngezinto ezishisiwe, njengoba kungaholela ezingozini phakathi nokuhlolwa futhi kube nomthelela ngokuphawulekayo ubude bempilo ye-crucible. Ukwengeza, lapho i-crucible ishisa ukushisa okuphezulu, ngokuvamile cishe ku-400-500 ° C, kubalulekile ukuyiphatha ngokucophelela futhi ugweme ukuyithinta ngezandla ezingenalutho njengoba ingabangela ukushisa okukhulu.
Ukukhethwa kwempahla ye-graphite crucibles kubandakanya ukucabangela izici ezilandelayo:
I-Refractoriness: I-graphite crucibles idinga ukuqina okuphezulu ukumelana nezinga lokushisa elidlulele. Ngakho-ke, kubalulekile ukuhlola ukumelana nomlilo kwe-graphite crucible material ukuqinisekisa ukusetshenziswa okuphephile.
Ukuzinza Kwekhemikhali: Izinsimbi ze-graphite zivame ukusetshenziswa ezinqubweni zamakhemikhali ezonakalisayo. Ngakho-ke, ukuzinza kwamakhemikhali we-crucible material kubalulekile ukuze kuncishiswe ukugqwala.
Ukuqina Nokuqina: Ukuqina nokuqina kwe-graphite crucible material kufanele kucatshangelwe ukuvimbela ukuphuka kwe-brittle ngesikhathi sokusetshenziswa.
Ngokunamathela kule mibandela engenhla yokukhetha impahla, singaqinisekisa ukusebenza kahle kwezinsimbi ze-graphite.
Sithemba ukuthi lokhu kuhlola kanye nemihlahlandlela yokukhetha izinto ezibonakalayo kuhlinzeka ngemininingwane ebalulekile yokukhiqiza kanye nokusetshenziswa kwama-graphite crucibles, okuvumela ukusebenza okuphephile nokusebenza kahle.
