Li-Crucibles tse Fetohang li Etsa bonnete ba ho qhibiliha ka mokhoa o Sebetsang le ho Hloekisa Litšepe

Crucible Bakeng sa ho Qhibiliha Koporo

Li-crucible li tla ka mefuta le litlhaloso tse fapaneng, li fana ka mefuta e mengata ea lisebelisoa ntle le ho lekanyetsoa ke tekanyo ea tlhahiso, boholo ba batch kapa mefuta e fapaneng ea lisebelisoa tse qhibilihisang. Ho feto-fetoha ha maemo ho tiisa ho ikamahanya le maemo ho matla le ho tiisa bohloeki ba thepa e qhibilihang.
Litaelo tsa Tšebeliso:
Kamora ho sebelisoa, beha crucible sebakeng se omileng 'me u qobe ho pepesehela metsi a pula. Pele o e sebelisa hape, butle-butle futhumatsa crucible ho likhato tse 500 tsa Celsius.
Ha u eketsa lisebelisoa ho crucible, qoba ho tlatsa ho thibela tšepe hore e se ke ea atolosa le ho senya crucible ka lebaka la ho atolosoa ha mocheso.
Ha u ntša tšepe e qhibilihisitsoeng ho crucible, sebelisa khaba neng kapa neng ha ho khoneha 'me u fokotse tšebeliso ea lipampiri. Haeba tongs kapa lisebelisoa tse ling li hlokahala, etsa bonnete ba hore li lumellana le sebopeho sa crucible ho thibela matla a mangata a sebakeng seo le ho lelefatsa bophelo ba eona.
Nako ea bophelo ea crucible e angoa ke tšebeliso ea eona. Qoba ho lebisa malakabe a phahameng a oxidation ka kotloloho holim'a crucible, kaha sena se ka baka oxidation e potlakileng ea thepa ea crucible.
Lisebelisoa tsa Tlhahiso ea Crucible: Lisebelisoa tsa tlhahiso ea li-crucible li ka akaretsoa ka mefuta e meraro e meholo: graphite ea tlhaho ea crystalline, letsopa la refractory la polasetiki, le lisebelisoa tse thata tse kang kaolin tse thata. Ho tloha ka 2008, lisebelisoa tsa maiketsetso tse hanyetsanang le mocheso o phahameng joalo ka silicon carbide, alumina corundum, le silicon iron le tsona li 'nile tsa sebelisoa e le lisebelisoa tsa moralo oa li-crucibles. Lisebelisoa tsena li ntlafatsa haholo boleng, letsoalo le matla a mochini a lihlahisoa tsa crucible.
Lisebelisoa: Li-crucibles li sebelisoa hangata bakeng sa:
Ho chesa lintho tse tiileng
Evaporation, mahloriso, kapa crystallization ea tharollo (ha lijana tse mouoane li le sieo, li-crucibles li ka sebelisoa ho e-na le hoo)
Lintlha tsa bohlokoa tsa tšebeliso:
Li-crucibles li ka futhumatsoa ka ho toba, empa ha lia lokela ho pholile ka potlako ka mor'a ho futhumatsa. Sebelisa matlapa a crucible ho a tšoara ha a chesa.
Beha crucible holim'a kgutlotharo ea letsopa nakong ea mocheso.
Hlohlelletsa lintho tse ka hare ha li fetoha mouoane 'me u sebelise mocheso o setseng bakeng sa ho omisa hoo ho seng ho felile.
Khethollo ea Li-crucibles: Li-crucible li ka aroloa ka ho pharaletseng ka lihlopha tse tharo: li-graphite crucibles, li-crucible tsa letsopa le li-crucibles tsa tšepe. Ka har'a sehlopha sa graphite crucible, ho na le li-crucibles tse tloaelehileng tsa graphite, li-crucible tsa graphite tse nang le sebōpeho se khethehileng, le li-crucible tsa graphite tse hloekileng haholo. Mofuta o mong le o mong oa crucible o fapana ka ts'ebetso, ts'ebeliso, le maemo a ts'ebetso, e lebisang phapanong ea lisebelisoa tse tala, mekhoa ea tlhahiso, mekhoa ea tlhahiso le litlhaloso tsa sehlahisoa.
Litlhaloso le Linomoro: Litlhaloso tsa Crucible (boholo) hangata li hlalosoa ka linomoro tse latellanang. Mohlala, crucible ea # 1 e ka ts'oara bolumo ea 1000g ea koporo mme e boima ba 180g. Matla a ho qhibiliha bakeng sa litšepe tse fapaneng kapa li-alloys li ka baloa ka ho atisa tekanyo ea boima ba 'mele ho ea boima ba crucible ka tšepe e loketseng kapa coefficient ea alloy.
Likopo tse khethehileng: Li-crucible tsa nickel li loketse lisampole tse qhibilihang tse nang le NaOH, Na2O2, Na2CO3, NaHCO3, le KNO3 ka li-solvents tsa alkaline. Leha ho le joalo, ha lia lokela ho qhibiliha lisampole tse nang le KHSO4, NaHS04, K2S2O7, kapa Na2S2O7, kapa metsoako e meng ea asiti, hammoho le sulfide ea alkaline e nang le sebabole.
Qetellong, li-crucibles li fana ka mefuta e fapaneng ea lits'ebetso liindastering tse fapaneng, 'me ka ho latela litataiso tse nepahetseng tsa ts'ebeliso, bophelo ba bona bo bolelele le bokhoni bo ka eketsoa.
