Ukuqonda imigaqo yokufunxa ubushushu yeGraphite Silicon Carbide Crucibles

I-graphite ye-silicon carbide cruciblesngamacandelo abalulekileyo kwizicelo ezahlukeneyo zobushushu obuphezulu, kubandakanya isinyithi, iilebhu zekhemikhali, kunye neenkqubo zoshishino. Ezi crucibles zidume ngeempawu zazo ezikhethekileyo zokufunxa ubushushu, eziyimfuneko ekugcineni uzinzo kunye nokusebenza kakuhle phantsi kweemeko ezinzima. Kweli nqaku, sihlolisisa imigaqo engaphantsi elawula amandla okufunxa ubushushu be-graphite silicon carbide crucibles.

1. Umthamo weThermal oPhezulu

Esinye sezizathu eziphambili zegraphite silicon carbide crucibles zigqwesa ekufunxeni ubushushu kumthamo wazo omkhulu wokufudumeza. Olu phawu lubavumela ukuba bathathe ngokukhawuleza kwaye bagcine inani elibalulekileyo lobushushu. Xa zibonakaliswe kumaqondo obushushu aphezulu, ezi crucibles azifunxa nje amandla kwindawo ezingqongileyo kodwa zikwagcina amaqondo obushushu aphezulu ixesha elide. Obu buchule bokumelana nokugcina amaqondo obushushu aphezulu bubenza babaluleke kakhulu kwiimvavanyo kunye neenkqubo ezifuna ukuvezwa kubushushu obugqithisileyo.

2. Iipropati zeMichiza

Ukongeza kumandla obushushu, iipropathi zeekhemikhali zegraphite silicon carbide crucibles zidlala indima ebalulekileyo ekufunxeni kwabo ubushushu. Kwiqondo lokushisa eliphakamileyo, inxalenye yegraphite ye-crucible inokusabela nge-oksijini ukwenza i-carbon dioxide gas. Le mpendulo ihamba kunye nokukhululwa kwamandla, igalelo kwi-crucible yokufunxa ubushushu. Ukudibana phakathi kokwakheka kweekhemikhali zezinto kunye neemeko zokusingqongileyo kwandisa amandla ayo okufunxa ubushushu ngokufanelekileyo.

3. Adsorption Izakhono

Iicrucibles ze-graphite silicon carbide nazo zinamandla okubhengeza, okubavumela ukuba batsale kwaye bagcine ukufuma kunye nobunye ukungcola okuvela kwindawo ezingqongileyo. Le propati ye-adsorption ibonelela ngendlela eyongezelelweyo yokufunxa ubushushu, iphinda ikhulise amandla okulawula ubushushu be-crucible.

Ukuqukumbela

Isixhobo sokufunxa ubushushu se-graphite silicon carbide crucibles yintsebenziswano entsonkothileyo yezinto zabo eziphathekayo kunye neempawu zekhemikhali. Umthamo wabo omkhulu we-thermal, indalo yekhemikhali esebenzayo, kunye nezakhono ze-adsorption ngokudibeneyo zinegalelo ekukwazini kwabo ukufunxa ngokufanelekileyo ubushushu kunye nokugcina uzinzo phantsi kweemeko zobushushu obugqithisileyo. Ezi mpawu zenza i-graphite silicon carbide crucibles ibe sisixhobo esibalulekileyo kwizicelo ezahlukeneyo zobushushu obuphezulu, ukuqinisekisa ukuchaneka kunye nokusebenza kakuhle kwiinkqubo ezifuna ulawulo olungqongqo lwe-thermal.
