Ukusetshenziswa kwe-silica ezimbozweni kuhilela kakhulu ukuthuthukisa ukunamathela, ukumelana nesimo sezulu, izakhiwo zokulwa nokuqina, kanye nokuthuthukisa i-thixotropy. Ifaneleka ezimbozweni zezakhiwo, ezimbozweni ezisekelwe emanzini, kanye nopende we-acrylic resin.
I. Ukuhambisana kwezinhlobo ze-Silica nezinhlelo zokumboza
1. I-Silica Efuthwe Ngomoya
Izindawo Zokusebenza: Izembozo ezilaphekayo ze-UV (isb., izembozo zokhuni ze-UV, izembozo zepulasitiki ze-UV), izembozo zefilimu eqinile yezimboni, kanye nezembozo zempuphu.
Izinzuzo Zokusebenza: I-thixotropy enamandla, imiphumela emihle kakhulu yokulwa nokuwa kanye neyokulwa nokuxazulula izinkinga.
Umthelela Wezindleko: Nakuba intengo yeyunithi iphezulu, umthamo odingekayo uphansi (0.5%–3%), okwenza izindleko zizonke zilawuleke.
2. I-Silica Enezimvula
Izindawo Zokusebenza: Izembozo zokwakha, izembozo zezimboni eziphakathi nendawo kuya kweziphansi.
Izinzuzo Zokusebenza: Izindleko eziphansi, yize kudingeka umthamo ophezulu (3%–10%); umphumela omuhle wokubumbana uma kuqhathaniswa ne-silica evuthayo.
Imikhawulo: Ukusatshalaliswa kosayizi wezinhlayiya ezibanzi, ukunemba okuphansi ekulawulweni kwe-rheology.
3. I-Silica Airgel
Izicelo Ezikhethekile: Izembozo ezingashi, izembozo ezivikelayo zemishini eshisa kakhulu.
Inkinga Yezindleko: Inqubo yokulungiselela eyinkimbinkimbi; izindleko zifinyelela emashumini ezinkulungwane ze-RMB/kg, ngaleyo ndlela zisetshenziswa kuphela emasimini anenani eliphezulu.
II. Ukuthuthukiswa Kokusebenza Kokumboza
1. Ukuthuthukiswa Kokusebenza Kwe-Rheology kanye Nokusetshenziswa
I-silica efumile yakha isakhiwo senethiwekhi esinezinhlangothi ezintathu ngokusebenzisa amaqembu e-hydroxyl angaphezulu, okunikeza i-thixotropy: ngaphansi kwamandla okusika, i-viscosity iyancipha ukuze kube lula ukuyisebenzisa; lapho i-static, i-viscosity iyalulama ukuze kuvinjelwe ukugoba nokwakheka komphetho. I-silica evundile ithuthukisa ukuzinza kwe-coating, ivimbela ukuqina kwe-pigment, futhi yandisa isikhathi sokugcina.
2. Ukulwa Nokugaywa Kwezinkukhu Nokuhlakazeka Okuthuthukisiwe
I-silica ethambile kakhulu, njengesithako sangaphandle, inamathela ebusweni be-powder coating ukuze idale "umphumela wokuthwala ibhola," ithuthukisa ukugeleza kanye nokumelana nokugaywa. Amandla aphezulu ebusweni be-silica efumile anciphisa isikhathi sokuhlakazeka futhi athuthukise ukufana kombala.
3. Ukuthuthukiswa Kokusebenza
Umphumela Wokubambana: Ama-microparticle e-Silica anciphisa ukukhanya ngokukhanya okusabalele, okwenza kube nokugqama okukhanyayo kuya kokungagqamile.
Izakhiwo Zomshini: Kuthuthukisa ubulukhuni bokumboza, ukumelana nokuguguleka, kanye nokumelana nesimo sezulu, okwandisa isikhathi senkonzo.
Izakhiwo Zokubona: Kuthuthukisa ukusabalala kwe-UV ukuze kukwazi ukulwa nokuguga ngenkathi kugcinwa ukukhanya.
4. Izimo Zokusebenza Ezikhethekile
Izembozo zefilimu ejiyile (isb., upende wasolwandle): Kuxhomeke ku-silica thixotropy efumile ukuqinisekisa ukujiya kwefilimu.
Ukwemboza phansi: Thuthukisa ukuleveli kanye nokumelana nokuklwebheka.
Ukukhetha Uhlobo: Izinhlobo ezahlukene ze-silica (ezifuthwe/ezimanzi) kufanele zikhethwe ngokusekelwe ezidingweni zokumboza—isibonelo, i-silica efuthwe ukuze kulawulwe i-rheology enembile, kuyilapho i-silica efuthwe inikeza ibhalansi engcono yokusebenza kwezindleko ekufakeni i-matting.
III. Izincomo Zokulinganisela Izindleko Nokusebenza
Izembozo zekhwalithi ephezulu (isb., izembozo zezimoto, izembozo ze-UV): I-silica efumile iyathandwa, naphezu kwentengo yayo ephezulu, njengoba ithuthukisa kakhulu ukusebenza (isb., ukumelana nokuguguleka okuphindwe kabili).
Izembozo eziphakathi kuya kweziphansi (isb., izembozo zezakhiwo): I-silica evundile inikeza isilinganiso esingcono sokusebenza kwezindleko, futhi ukuhambisana kungathuthukiswa ngokuguqulwa kwendawo.
Izidingo ezikhethekile zokusebenza (ukungashisi umlilo/ukushisa): I-silica airgel ayinakushintshwa kodwa idinga ukuhlolwa okuphelele kokusebenza kahle kwezindleko.
Isiphetho: Embonini yokugqoka, i-silica yehlisa izindleko eziphelele ngokungaqondile ngokuthuthukisa ukusebenza. Kodwa-ke, intengo yezinto zokusetshenziswa kanye nokutshalwa kwezimali kwenqubo kumele kulinganiswe. Ukusetshenziswa okuphezulu kuvame ukusebenzisa i-silica evuthayo, kuyilapho izimakethe eziphakathi kuya kweziphansi zikhetha i-silica evundile ukuze kube nokusebenza kahle kwezindleko.
