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 e sebetsana 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.Ka hona, botsitso ba lik'hemik'hale ba thepa ea 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.
