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.

Thepa:

1. Ho hanyetsa mocheso o phahameng haholo:Clay graphite cruciblee itšetlehile ka mokhoa o babatsehang oa ho tsamaisa mocheso oa graphite 'me e khona ho mamella mocheso o phahameng ho fihlela ho 1800 ° C ntle le ho nolofatsa kapa ho qhibiliha. E loketse haholo-holo liteko tsa mocheso o phahameng le ho qhibilihisa indasteri.
2. Matla a phahameng: Graphite le letsopa li kopantsoe ho etsa lisebelisoa tse nang le matla a phahameng, tse etsang hore crucible e se ke ea robeha ha e le tlas'a tšusumetso ea ka ntle 'me e na le nako e ntle ea nako e telele.
3. Khanyetso e matla ea kutu: Ho hanyetsa kutu ea tlhaho ea graphite ho etsa hore letsopa la graphite crucible le sebelisoe nako e telele libakeng tse fapaneng tse senyang, 'me li loketse ho boloka le ho sebetsana le litharollo tse fapaneng tse senyang.Likarolo tsa tšebeliso
   Clay graphite crucible e na le mefuta e mengata ea ts'ebeliso le ts'ebetso e ntle haholo, haholo-holo:
   1. Tšebeliso e pharaletseng: Ebang ke tlhahlobo ea laboratori, alchemy, kapa liteko tse ling tsa lik'hemik'hale, letsopa la graphite crucible le loketse ts'ebetso e fapaneng ea mocheso o phahameng 'me ke khetho e nepahetseng.
   2. Bophelo ba nako e telele ea tšebeletso: Ka lebaka la thepa ea eona e phahameng, li-crucible tsa letsopa tsa graphite hangata li ka sebelisoa ka makhetlo a makholo, ho fokotsa haholo makhetlo a mangata le litšenyehelo tsa ho nkela sebaka.
   3. Tlhokomelo e bonolo le e bonolo: Sebaka sa crucible se boreleli ebile ho bonolo ho se hloekisa, 'me tlhokomelo ea letsatsi le letsatsi e bonolo haholo, e fa basebelisi boiketlo bo boholo.

   Mehato ya tlhokomelo
   E le ho netefatsa ts'ebetso e ntle ka ho fetisisa le bophelo bo bolelele ba tšebeletso ea letsopa la graphite crucible, lintlha tse latelang li lokela ho lebisoa tlhokomelo nakong ea tšebeliso:

   1. Qoba tikoloho ea oxidizing: Ha ho khothalletsoe ho sebelisa li-crucibles tse nang le likarolo, lintho kapa litharollo tse nang le oxidized habonolo ho thibela tšenyo ea oxidative.
   2. Khetho e nepahetseng ea bokhoni: Ha u sebelisa, u lokela ho khetha bokhoni bo loketseng ba crucible le ho laola ho hlahisa mocheso ho qoba tšenyo ea crucible ka lebaka la ho phahama ka tšohanyetso ha mocheso.
   3. Qoba tšebeliso ea nako e telele ea mocheso o phahameng: Litharollong tse senyang tse kang acid e matla le alkali e matla, tšebeliso ea nako e telele ea mocheso o phahameng e lokela ho qojoa ka hohle kamoo ho ka khonehang ho qoba ho ama ho tšoarella ha crucible.

   Ha re phethela
   Ka kakaretso, letsopa graphite crucible e se e le sesebelisoa sa bohlokoa bakeng sa ts'ebetso e phahameng ea mocheso lilaboratoring le libakeng tsa indasteri ka lebaka la ho hanyetsa mocheso o phahameng haholo, matla a phahameng le ho hanyetsa kutu. Tšebeliso e nepahetseng le tlhokomelo e ka netefatsa bophelo ba eona bo bolelele ba ts'ebeletso le ts'ebetso e tsitsitseng. Clay graphite crucible e bonts'a menyetla e mengata ea ts'ebeliso ea ho qhibiliha, indasteri ea lik'hemik'hale, laboratori le likarolo tse ling, 'me ke khetho e nepahetseng bakeng sa liteko tsa hau tsa mocheso o phahameng le tlhahiso.
