Ekuphishekeleni ukukhulisa ubude bempilo kanye nokusebenzisa izici zeama-graphite crucibles, imboni yethu yenze ucwaningo olunzulu nokuhlola ekukhiqizeni nasekusebenzeni kwayo.Nansi imiyalo yokusebenza yezinsimbi ze-graphite:
Izinyathelo zokuphepha ezikhethekile ze-high-purity graphite crucibles:
Gwema ukushayisana kwemishini futhi ungawisi noma ushaye i-crucible usuka phezulu.Futhi gcina yomile futhi kude ifomu umswakama.Ungawathinti amanzi ngemva kokuba esebasiwe futhi omisiwe.
Uma usebenzisa, gwema ukuqondisa ilangabi ngqo phansi kwe-crucible.Ukuchayeka elangabini eliqondile kungashiya amamaki amnyama abalulekile.
Ngemva kokuvala isithando somlilo, susa noma iyiphi i-aluminiyamu esele noma impahla yethusi ku-crucible futhi ugweme ukushiya noma iyiphi insalela.
Sebenzisa izinto ezine-asidi (ezifana nokuguquguquka) ngokulingene ukuze uvimbele ukugqwala nokuqhekeka kwe-crucible.
Uma wengeza izinto, gwema ukushaya i-crucible futhi uyeke ukusebenzisa amandla omshini.
Ukugcinwa nokudluliswa kwama-graphite crucibles:
I-high-purity graphite crucibles iyazwela emanzini, ngakho-ke kufanele ivikelwe ekumswakama nokuchayeka kwamanzi.
Naka ukugwema ukulimala kwendawo.Ungabeki i-crucible ngqo phansi;esikhundleni salokho, sebenzisa i-pallet noma ibhodi lesitaki.
Uma uhambisa i-crucible, gwema ukuyigingqa ibhekise eceleni phansi.Uma idinga ukuphendukiswa iqonde phezulu, beka ikhadibhodi eliwugqinsi noma indwangu phansi ukuze uvimbele imihuzuko noma imihuzuko phansi.
Ngesikhathi sokudlulisa, qaphela ngokukhethekile ukuthi ungawisi noma ushaye i-crucible.
Ukufakwa kwezinsimbi ze-graphite:
I-crucible stand (iplatifomu e-crucible) kufanele ibe nobubanzi obufanayo noma obukhudlwana njengendawo engezansi ye-crucible.Ubude beplatifomu kufanele bube phezulu kunombobo welangabi ukuze kuvinjwe ilangabi ukuthi lifinyelele ku-crucible ngokuqondile.
Uma usebenzisa izitini eziphikisayo endaweni yesikhulumi, izitini eziyindilinga zikhethwa, futhi kufanele zibe flat ngaphandle kokugoba.Gwema ukusebenzisa izitini eziyingxenye noma ezingalingani, futhi kunconywa ukusebenzisa amapulatifomu e-graphite angenisiwe.
Beka indawo yokumisa ama-crucible phakathi nendawo yokuncibilika noma ukucwiliswa, bese usebenzisa impushana ye-carbon, i-rice husk ash, noma ukotini ophikisayo njengomcamelo ukuze uvimbele ukuthi i-crucible inganamatheli esitendini.Ngemuva kokubeka i-crucible, qiniseka ukuthi ilinganisiwe (usebenzisa izinga lomoya).
Khetha izinsimbi ezilinganayo ezihambisana nesithando somlilo, futhi ugcine igebe elifanele (okungenani (okungenani (40mm)) phakathi kwe-crucible nodonga lwesithando somlilo.
Uma usebenzisa i-crucible ene-spout, shiya isikhala esilinganiselwa ku-30-50mm phakathi kwe-spout nesitini esiphikisayo ngezansi.Ungabeki lutho ngaphansi, futhi sebenzisa ukotini ophikisayo ukwenza bushelelezi ukuxhumana phakathi kwe-spout nodonga lwesithando somlilo.Udonga lwesithando somlilo kufanele lube nezitini eziqinile eziphikisayo (amaphuzu amathathu), kanye nekhadibhodi likathayela cishe u-3mm ubukhulu kufanele libekwe ngaphansi kwe-crucible ukuvumela ukunwetshwa okushisayo ngemva kokushisa.
Ukushisa kanye nokomisa kwezinsimbi ze-graphite:
Shisisa i-crucible eduze kwesithando somlilo samafutha amahora angu-4-5 ngaphambi kokusetshenziswa ukuze usize ekususeni umswakama endaweni ye-crucible.
Ezitsheni ezintsha, faka amalahle noma ukhuni ngaphakathi kwe-crucible bese uyishisa cishe amahora amane ukuze usize ukususa umswakama.
Izikhathi zokushisisa ezinconyiwe ze-crucible entsha zimi kanje:
0℃ ukuya ku-200℃: Khulisa kancane izinga lokushisa ngaphezu kwamahora angu-4.
Ezithandweni zikawoyela: Khulisa izinga lokushisa kancane kancane ihora elingu-1, lisuka ku-0℃ liye ku-300 ℃, futhi lidinga amahora angu-4 ukusuka ku-200℃ liye ku-300℃,
Ezithandweni zikagesi: dinga amahora ama-4 wokushisisa ukusuka ku-300 ℃ kuye ku-800 ℃, bese amahora ama-4 ukusuka ku-300 ℃ kuye ku-400 ℃.kusuka ku-400 ℃ kuya ku-600 ℃, khulisa izinga lokushisa ngokushesha futhi ugcine amahora ama-2.
Ngemva kokuvala isithando somlilo, izikhathi ezinconyiwe zokushisisa kabusha zimi kanje:
Okwezithando zikawoyela nezikagesi: Kudingeka ihora elingu-1 isikhathi sokushisisa ukusuka ku-0℃ ukuya ku-300℃.Udinga amahora angu-4 wokushisisa ukusuka ku-300℃ ukuya ku-600℃.Khulisa ngokushesha izinga lokushisa liye ezingeni olifunayo.
Izinto zokushaja:
Uma usebenzisa i-high-purity graphite crucibles, qala ngokungeza izinto ezincane zamakhona ngaphambi kokwengeza izingcezu ezinkulu.Sebenzisa izindlawu ukubeka ngokucophelela nangokuthula izinto ku-crucible.Gwema ukulayisha ngokweqile i-crucible ukuze uvimbele ukuthi ingaphuki.
Ezithandweni zikawoyela, izinto zokwakha zingangezwa ngemva kokufinyelela ku-300 ℃.
Okwezithando zikagesi:
Ukusuka ku-200 ℃ kuya ku-300 ℃, qala ukungeza izinto ezincane.Kusukela ku-400℃ kuye phambili, kancane kancane engeza izinto ezinkulu.Uma ungeza izinto ngesikhathi sokukhiqiza okuqhubekayo, gwema ukuzifaka endaweni efanayo ukuze uvimbele i-oxidation emlonyeni we-crucible.
Ukuze uthole izithando zokushisa zikagesi, shisa kuqala ku-500 ℃ ngaphambi kokuthela i-aluminium encibilikayo.
Izinyathelo zokuqapha ngesikhathi sokusetshenziswa kwe-graphite crucibles:
Bamba izinto ngokunakekela uma uzingeza ku-crucible, ugwema ukubeka ngamandla ukuze uvimbele ukulimaza i-crucible.
Kuma-crucible asetshenziswa ngokuqhubekayo amahora angama-24, impilo yawo inganwetshwa.Ekupheleni kosuku lomsebenzi kanye nokuvalwa kwesithando somlilo, izinto ezincibilikisiwe ku-crucible kufanele zisuswe ukuze kuvinjelwe ukuqina nokwanda okulandelayo, okungaholela ekushintshashintsheni kwe-crucible noma ukuphuka.
Uma usebenzisa izinto ezincibilikayo (ezifana ne-FLLUX kuma-alloys e-aluminium noma i-borax kuma-alloys ethusi), zisebenzise kancane ukuze ugweme ukugqwala kwezindonga ezibohlayo.Engeza ama-agent lapho ukuncibilika kwe-aluminium sekukude nemizuzu engu-8 ukuthi igcwale, inyakaze ngobumnene ukuze ibavimbele ekubambeleleni ezindongeni ezibhobozayo.
Qaphela: Uma i-ejenti encibilikayo iqukethe ngaphezu kuka-10% we-sodium (Na) okuqukethwe, kudingeka i-crucible ekhethekile eyenziwe ngezinto ezithile.
Ekupheleni kosuku ngalunye lomsebenzi, ngenkathi i-crucible isashisa, susa ngokushesha noma iyiphi insimbi enamathela ezindongeni ezihlabayo ukuze uvimbele izinsalela eziningi, ezingase zithinte ukudluliswa kokushisa nokwandisa isikhathi sokuhlakazeka, okubangela ukwanda okushisayo kanye nokuqhekeka okungenzeka kwe-crucible.
Kunconywa ukuthi uhlole isimo se-crucible cishe njalo ezinyangeni ezimbili ukuze uthole ama-alloys e-aluminium (masonto onke ama-alloys ethusi).Hlola indawo yangaphandle bese uhlanza igumbi lesithando somlilo.Ukwengeza, zungezisa i-crucible ukuze uqinisekise ukuguga, okusiza ukunweba ubude besikhathi sempilo ye-high-purity graphite crucibles.
Ngokulandela le miyalo yokusebenza, abasebenzisi bangakwazi ukukhulisa isikhathi sokuphila nokusebenza kahle kwe-graphite crucibles yabo, baqinisekise ukusebenza okuhle ezinhlelweni ezihlukahlukene.
