Sebōpi sa Graphite sa letsopa
Sebōpi sa Graphite sa Clay (se boetse se bitsoa Sebōpi sa Graphite se Kopantsoeng sa Clay)ke mofuta oa sejana sa ho qhibilihisa se sebetsang hantle, se entsoeng ka graphite e hloekileng haholo le letsopa le hanyetsang e le thepa e tala ea mantlha, ka ho kopanya, ho bopa, ho besa ka mocheso o phahameng le ts'ebetso e khethehileng ea ho phekola.
E kopanya melemo ea graphite (mocheso o motle oa ho tsamaisa mocheso, ho hanyetsa mocheso o phahameng) le letsopa (matla a matle, ho hanyetsa oxidation, sebopeho se tsitsitseng), e leng se etsang hore e be sebōpi sa setso se sebelisoang haholo bakeng sa ho qhibilihisa tšepe e seng ea ferrous, ho e lahla le ho qhibiliha ha laboratori.
Sekhahla sa ho Itlhophisa:
1. Ho iketsetsa boholo:Bophara ba kahare bo ka fetoloang, bophara ba kantle, bophahamo le botenya ba lebota, ho tloha ho di-crucible tse nyane tsa laboratori ho isa ho tse kgolo tsa indasteri.
2. Ho iketsetsa Sebopeho:Selikalikoe/sekhoune se tloaelehileng, kapa se nang le sebopeho se ikgethang (sekwere, se elliptical, se nang le kou/tsebe e khelosang) bakeng sa disebediswa tse ikgethang.
3. Ho iketsetsa karo-karolelano ea thepa:Karolelano ea graphite-letsopa e ka fetoloang (boleng ba graphite bo ikhethileng) ho latela tšepe e qhibilihisitsoeng, mocheso oa ho sebetsa le bophelo ba ts'ebeletso.
4. Tlhahisoleseding e qaqileng:Boreledi ba lebota la kahare bo iketseditsweng, kalafo ya lebota la kantle e thibelang ho thella le ho betla (letshwao, ditlhaloso) ha ho hlokahala.
Litšobotsi tsa Bohlokoa le Melemo:
1. Ho tsamaisa mocheso hantle haholo, ho futhumatsa ka potlako le katleho e phahameng ea ho qhibiliha, ho boloka nako ea tlhahiso haholo
2. Khanyetso e matla ea mocheso o phahameng, mocheso o sireletsehileng oa ho sebetsa ho fihlela ho 1200℃–1650℃, o loketse maemo a fapaneng a ho qhibiliha ha mocheso o phahameng
3. Ho hanyetsa oxidation hantle, sekhahla sa khoholeho ea mobu se liehang le bophelo bo bolelele ba ts'ebeletso, ho fokotsa litšenyehelo tsa ho nkela sebaka le tahlehelo ea nako ea ho phomola
4. Boima bo phahameng, masoba a tlase, ho hanyetsa mocheso hantle, ha ho bonolo ho petsoha kapa ho robeha nakong ea ts'ebeliso
5. Matla a matle a mechini le khanyetso ea tšusumetso, e loketse liteko tse nyane tsa ho qhibiliha ha boima ba indasteri le tsa laboratori
6. Thepa e tsitsitseng ea lik'hemik'hale, ha ho na tšilafalo ho litšepe tse qhibilihisitsoeng, ho netefatsa bohloeki ba sehlahisoa (haholo-holo se loketse ho qhibiliha ha tšepe ea bohlokoa)
7. Boreletsa lebota la kahare, le bonolo ho hlwekisa le ho tshela tshepe e qhibilihisitsweng, le fokotsang ditshila tsa thepa
8. Litlhaloso tse felletseng, boholo bo ka fetoloang, sebopeho le karolelano ea thepa ho latela litlhoko tsa bareki, ho ikamahanya le lisebelisoa tse khethehileng le maemo a mosebetsi
