Hollow microspheres cenospheres bakeng sa li-sealant tsa mocheso o phahameng le likhomaretsi
Li-cenospheres li ka bapala likarolo tse 'maloa ho li-sealants le li-adhesive tse nang le mocheso o phahameng. Li-cenospheres li bobebe, likotoana tse se nang letho tse entsoeng haholo-holo ka silika le alumina, tseo hangata li fumanoang e le sehlahisoa sa ho tuka ha mashala lifemeng tsa motlakase. Ha e kenngoa ka har'a li-sealants le li-adhesives,cenospheres e ka fana ka melemo e fapaneng,haholo-holo lits'ebetsong tsa mocheso o phahameng . Tse ling tsa likarolo tseo ba li bapalang ke tsena:
Mocheso oa mocheso : Li-cenospheres li na le thepa e ntle ea ho itšireletsa ka lebaka la sebopeho sa tsona se sekoti. Ha li kenngoa ho li-sealants le li-adhesives, li etsa mokoallo o fokotsang mocheso oa mocheso, kahoo o thusa ho sireletsa substrate kapa motsoako ho tloha mocheso o phahameng. Thepa ena ea ho kenya letsoho e bohlokoa haholo lits'ebetsong moo ho fokotsa mocheso ho hlokahalang ho fokotsoa.
Boima bo fokotseng : Li-cenospheres li bobebe, ho bolelang hore li ka fokotsa haholo boholo ba li-sealants le li-adhesives ha li kenyelelitsoe mefuteng ea tsona. Tšobotsi ena e bobebe ea lakatseha lits'ebetsong moo boima ba thepa bo hlokang ho fokotsoa, joalo ka sebakeng sa sefofane kapa lisebelisoa tsa likoloi.
Rheology e ntlafalitsoeng : Ho eketsoa ha li-cenospheres ho ka ntlafatsa thepa ea rheological ea li-sealants tse phahameng tsa mocheso le li-adhesives. Ba sebetsa e le mahlahana a thixotropic, ho bolelang hore ba ka thusa ho laola ho phalla le viscosity ea thepa. Thepa ena e lumella sealant kapa sekhomaretsi hore se sebelisoe habonolo, se hasane, 'me se khomarele holimo ha se ntse se boloka sebopeho sa sona le botsitso.
Lisebelisoa tse ntlafalitsoeng tsa mochini : Li-cenospheres li ka ntlafatsa matla a mochini le ho hanyetsa ha li-sealants le likhomaretsi. Ha li kenngoa, li ka matlafatsa thepa, li ntlafatsa ho hanyetsa khatello ea kelello le deformation. Thepa ena ea matlafatso e na le molemo ka ho khetheha lits'ebetsong tsa mocheso o phahameng moo thepa e ka bang tlas'a libaesekele tse futhumetseng kapa khatello ea mochini.
Ho hanyetsa lik'hemik'hale : Cenospheres e fana ka khanyetso e ntle ea lik'hemik'hale, e etsa hore e tšoanelehe bakeng sa lits'ebetso moo sealant kapa sekhomaretsi se hlokang ho mamella ho pepesehela lik'hemik'hale tse fapaneng, li-acid kapa alkalis. Li ka thusa ho ntlafatsa khanyetso ea lik'hemik'hale ka kakaretso ea thepa, ho matlafatsa nako ea eona le nako ea bophelo.
Ke habohlokoa ho hlokomela hore mesebetsi le melemo e khethehileng ea li-cenospheres ho li-sealants le li-adhesives tse nang le mocheso o phahameng li ka fapana ho itšetlehile ka sebopeho, tšebeliso, le lisebelisoa tse ling tse sebelisoang hammoho le tsona.
