Lisebelisoa tsa cenospheres ho Foundries ke life?
1.Lintho tse Refractory tse bobebe: Li-cenospheres li bobebe, li na le likaroloana tse se nang lethoe babatsehang insulating thepa. Li ka ekeletsoa ho thepa ea refractory e sebelisoang ho li-foundries ho fokotsa bongata ba thepa ntle le ho senya matla a eona. Sena se thusa ho finyellaho boloka matlalentlafatsa ts'ebetso e akaretsang ea ts'ebetso ea ts'ebetso.
2.Ho Tlatsa Core : Cenospheres e ka sebelisoa e le lisebelisoa tsa ho tlatsa li-cores tsa motheo. Li-Foundry cores li sebelisetsoa ho etsa li-cavities le libopeho tse rarahaneng ho li-castings. Ka ho kenyelletsa li-cenospheres ho thepa ea mantlha, boima ba mantlha bo fokotsehile, bo etsa hore ho be bonolo ho sebetsana le ho etsa hore tšebeliso e fokotsehileng ea thepa ea mantlha e theko e boima.
3.Keketso ea lehlabathe : Li-cenospheres li ka kopanngoa le lehlabathe la motheo ho ntlafatsa thepa ea tsona. Ho eketsoa ha li-cenospheres ho ka ntlafatsa phallo ea lehlabathe, ho fokotsa sekhahla sa lona, le ho ntlafatsa boleng ba ho lahla ka kakaretso. Li-cenospheres li boetse li fana ka mokelikeli oa mocheso ho hlobo, e leng se bakang ho fokotseha ha linako tsa ho tiisa le ho ntlafatsa ho qeta ho lahla.
4.Thermal Barrier Coatings : Li-cenospheres li ka sebelisoa ho li-coatings tsa thermal barriers (TBCs) tse sebelisoang ho hlobo le li-cores. Li-TBC li sebelisetsoa ho sireletsa hlobo le li-cores ho pepesehela mocheso o phahameng, ho thibela ho peperana le ho ntlafatsa bophelo ba tsona ka kakaretso. Li-cenospheres li ka kenyelletsoa ho lihlahisoa tsa TBC ho ntlafatsa thepa ea tsona ea ho sireletsa le ho fokotsa mocheso oa mocheso.
5.Tlhophiso : Cenospheres e ka sebelisoa e le mokhoa oa ho sefa ho li-Foundries. Li ka eketsoa ho li-filters tse sebelisoang lits'ebetsong tsa tšepe tse qhibilihisitsoeng ho tšoara litšila le likaroloana tse tiileng, tse hlahisang tšepe e hloekileng le boleng bo ntlafetseng ba ho lahla.
6. Li-Fillers tse bobebe: Li-cenospheres li ka sebelisoa e le li-fillers tse bobebe lihlahisoa tsa lihlahisoa, tse kang liphahlo le li-composite. Ba ntlafatsa karo-karolelano ea matla ho boima ba sehlahisoa sa ho qetela, ba fokotsa sekhahla, 'me ba matlafatsa thepa ea ho kenya letsoho.
Ka kakaretso, li-cenospheres li fumana lits'ebetso tse fapaneng litsing tsa motheo, ho tloha ho lisebelisoa tse bobebe tse bobebe ho isa ho ho tlatsoa ha mantlha, li-additives tsa lehlabathe, li-barriers barriers, filtration le li-filter tse bobebe. Mehaho ea bona e ikhethang e ba etsa tlatsetso ea bohlokoa bakeng sa ho ntlafatsa lits'ebetso tsa foundry le ho ntlafatsa boleng le katleho ea ts'ebetso ea ho lahla.
Li-cenospheres ke li-microspheres tse bobebe, tse se nang letho tseo hangata li sebelisoang e le lisebelisoa tsa ho tlatsa lits'ebetsong tse fapaneng, ho kenyeletsoa lits'ebetso tsa ho qala joalo ka ho lahla. Matsoho a riser, a tsejoang hape ka hore ke li-feeders, a sebelisoa ha ho etsoa casting ho fana ka phepelo e tsitsitseng ea tšepe e qhibilihisitsoeng ho lefella ho honyela ha tšepe e fola le ho tiea. Ho kenyelletsa li-cenospheres ho li-sleeve tsa riser ho ka fana ka melemo e itseng, empa ts'ebeliso ea tsona e hloka ho nahanisisoa ka hloko.
Mona ke kamoo li-cenospheres li ka sebelisoang ka matsoho a risepe le melemo e ka bang teng:
Boima bo Fokotseng: Li-cenospheres li bobebe, tse ka thusang ho fokotsa boima ba kakaretso ea sleeve ea riser. Sena se ka ba molemo lits'ebetsong moo boima ba riser bo lokelang ho fokotsoa.
Insulation: Li-cenospheres li na le thepa e ntle ea ho itšireletsa. Ho li kenya holim'a letsoho la risepe ho ka thusa ho fokotsa tahlehelo ea mocheso ho tloha tšepe e qhibilihisitsoeng, ho e lumella ho lula nako e telele e qhibiliha le ho etsa bonnete ba ho fepa ka katleho ha ho ntse ho tiisa.
Controlled Cooling: Thepa e sireletsang ea cenospheres e ka lebisa ho pholiso e laoloang le butle-butle ea tšepe e qhibilihisitsoeng ka har'a letsoho la risepe. Pholiso ena e laoloang e ka fokotsa sebopeho sa likoli joalo ka meokho e chesang le mapetsong a ho lahla.
Matšeliso a Shrinkage: Cenospheres e ka thusa ho lefella shrinkage e tiileng ka ho fana ka mohloli oa tšepe e qhibilihisitsoeng ha ho pholile ho pholile. Sena se ka ntlafatsa boleng ba kakaretso ea "casting" ka ho fokotsa menyetla ea mathata a amanang le shrinkage.
