Ke Hobane'ng ha U Sebelisana le Rona?

Ha u re khetha, u fumana ho feta sehlahisoa-u fumana molekane.

• Bohlale: Lilemo tse mashome tsa boiphihlelo indastering ea metheo.
• Customization: Litharollo tse etselitsoeng ho fihlela litlhoko tsa hau tse ikhethileng.
• Tšehetso: Ho tloha khetho ho ea ho kenya, re na le uena mohato o mong le o mong oa tsela.

Carbon Crucible ke bahale ba sa tsejoeng ba ho akhela tšepe. Ebile, ba bapala karolo ea bohlokoa ho sebetsana le mathata a thata ka ho fetisisa a ho qhibiliha libakeng tsa motheo le maemo a mocheso o phahameng. A na u ne u tseba hore li-crucibles tsee li khona ho mamella mocheso o feteletseng oa 1600 ° C? Seo ha se ntho e nyane! Ho tšoarella ha tsona, ho kopantsoe le mokhoa o ikhethang oa mocheso, ho etsa hore e be tsa bohlokoa haholo lefatšeng la tšepe.

Morero oa rona e tla ba ho ba mofani oa thepa ea theknoloji e phahameng le lisebelisoa tsa puisano ka ho fana ka sebopeho se ekelitsoeng, tlhahiso ea maemo a lefats'e, le bokhoni ba ts'ebeletso bakeng sa Carbon Crucible, Khamphani ea rona e tla tsoelapele ho latela "boleng bo phahameng, bo tsebahalang, mosebelisi pele" ka pelo eohle. Re amohela ka mofuthu metsoalle e tsoang likarolong tsohle tsa bophelo ho etela le ho fana ka tataiso, ho sebetsa 'moho le ho theha bokamoso bo khanyang!
Li-Carbon Bonded Silicon Carbide Crucibles li sebelisoa haholo masimong a ho qhibilihisa le ho lahlela litšepe tse fapaneng tse se nang ferrous joalo ka koporo, aluminium, khauta, silevera, lead, zinki le lialloys. Tšebeliso ea li-crucibles tsena e fella ka boleng bo tsitsitseng, bophelo bo bolelele ba tšebeletso, ho fokotsa haholo tšebeliso ea mafura le matla a mosebetsi. Ho feta moo, e ntlafatsa katleho ea mosebetsi le ho fana ka melemo e babatsehang ea moruo.

Lisebelisoa le Kaho
Li-crucible tsa graphite li entsoe ka lisebelisoa tse 'maloa:

• Graphite (45-55%): Karolo ea mantlha, e fanang ka phetisetso e ntle ea mocheso le botsitso ba mocheso.
• Silicon carbide, silica, le letsopa: Lisebelisoa tsena li matlafatsa matla a mochini oa crucible le ho hanyetsa ho bola, haholo-holo maemong a mocheso o feteletseng.
• Clay binder: E netefatsa momahano e nepahetseng ea thepa, e fa crucible sebopeho sa eona le botšepehi ba sebopeho.

Boholo ba karoloana ea graphite e sebelisitsoeng le bona bo fapana ho latela boholo le morero oa crucible. Ka mohlala, li-crucibles tse kholo li sebelisa graphite e mahoashe, ha li-crucible tse nyenyane li hloka graphite e ntle bakeng sa ho nepahala le ho sebetsa hantle.

Lisebelisoa tsa Graphite Crucible
Graphite carbon crucibles e sebelisoa haholo makaleng a fapaneng:

• Ho lahla tšepe e seng ferrous: E loketse litšepe tse kang koporo, khauta, silevera le koporo ka lebaka la coefficient ea tsona e tlase ea katoloso ea mocheso.
• Li-firnaces tsa induction: Maemong a mang, li-crucible li etselitsoe ho sebetsa ka maqhubu a khethehileng a sebōpi ho ntlafatsa matla a matla le taolo ea mocheso.
• Ts'ebetso ea lik'hemik'hale: Ho tsitsa ha tsona ka lik'hemik'hale ho li etsa hore li tšoanelehe ho sebelisoa libakeng tse pepesehileng lintho tse nang le asiti kapa alkaline.

Malebela a Bohlokoa a Tlhokomelo
Ho eketsa nako ea bophelo ea graphite carbon crucible, tlhokomelo e nepahetseng le polokelo li bohlokoa:

1. Cooling: Netefatsa hore crucible e pholile ka ho feletseng pele e bolokoa ho thibela mocheso oa mocheso.
2. Ho hloekisa: Kamehla tlosa tšepe e setseng le ho phalla ka mor'a tšebeliso e 'ngoe le e' ngoe ho thibela tšoaetso.
3. Ho boloka: Boloka crucible sebakeng se omeletseng, hole le mehloli ea mocheso o tobileng, ho qoba ho monya mongobo, ho ka lebisang ho senyeha ha sebopeho.
