Li-crucible tsa graphiteli sebelisoa haholo lits'ebetsong tse fapaneng, 'me ho bohlokoa ho etsa tlhahlobo e phethahetseng le ho khetha thepa e nepahetseng ka hloko. Litaelo tse ling tsa ho hlahloba le ho khetha ke tsenalikotlolo tsa graphite:
Pele o Sebelisa Tlhahlobo: Pele o sebelisagraphite crucible, hlahloba mapetsong le tšenyo. Ehlile ha ho na mapetsong a bonahalang, hoa hlokahala ho futhumatsa crucible ho mocheso o ka holimo ho 600 ° C ho etsa bonnete ba ho omisa ka ho feletseng.
Tokisetso ea Tikoloho: Etsa bonnete ba hore ha ho na metsi a bokelletsoeng ka sebōping kapa sekoting moo crucible e tla behoa teng. Hape, boloka lintho tse sa amaneng hole le sebaka sa graphite crucible.
Ho sebetsana le Material: Nka mehato ea ho itšireletsa ha u tšoara thepa ea sebōpi. Netefatsa hore lisebelisoa ha li phatlohe 'me li chesitsoe pele 'me li omisitsoe hantle. Ha u eketsa lisebelisoa ho graphite crucible, e etse butle-butle le ka mokhoa o tsitsitseng.
Ho bohlokoa ho latela litataiso tsena tsa tlhahlobo ho thibela likotsi tse ka bang teng le ho phatloha ha u sebelisa li-crucible tsa graphite.
Li-crucible tsa graphite li sebelisoa haholo ho futhumatsa lisebelisoa tsa liteko. Li na le boholo le mefuta e sa tšoaneng, e lumellang khetho ea crucible e loketseng ho latela palo, mofuta, le katoloso ea mocheso oa thepa e futhumatsang. Ho bohlokoa ho qoba ho tlatsa crucible ka lintho tse futhumetseng, kaha sena se ka baka likotsi nakong ea liteko mme sa ama bophelo ba crucible haholo. Ho phaella moo, ha crucible e futhumetse ho mocheso o phahameng, hangata o pota-potileng 400-500 ° C, ke habohlokoa ho sebetsana le eona ka hloko le ho qoba ho e tšoara ka matsoho a sa roala letho kaha e ka baka ho chesa ho matla.
Khetho ea thepa bakeng sa li-crucible tsa graphite e kenyelletsa ho nahana ka lintlha tse latelang:
Refractoriness: Graphite crucibles hloka refractoriness e phahameng ho mamella mocheso o feteletseng. Ka hona, ho bohlokoa ho lekola ho hanyetsa mollo ha thepa ea graphite crucible ho netefatsa ts'ebeliso e bolokehileng.
Botsitso ba Lik'hemik'hale: Li-crucible tsa graphite li atisa ho sebelisoa lits'ebetsong tsa lik'hemik'hale tse senyang. Kahoo, botsitso ba lik'hemik'hale ba lintho tse crucible bo bohlokoa ho fokotsa kutu.
Ho thatafala le ho tiea: Ho thatafala le ho tiea ha thepa ea graphite crucible e lokela ho nkoa e le ho thibela ho robeha ha brittle nakong ea tšebeliso.
Ka ho khomarela litekanyetso tse ka holimo tsa khetho ea thepa, re ka netefatsa ts'ebetso e nepahetseng ea li-crucible tsa graphite.
Re tšepa hore tataiso ena ea tlhahlobo le khetho ea thepa e fana ka lintlha tsa bohlokoa bakeng sa tlhahiso le tšebeliso ea li-graphite crucibles, tse lumellang hore ho be le ts'ebetso e sireletsehileng le e sebetsang hantle.
