Ukusetyenziswa kwe-silica kwiingubo kubandakanya ukuphucula ukunamathela, ukumelana nemozulu, iimpawu zokungahlali kakuhle, kunye nokuphucula i-thixotropy. Ifanelekile kwiingubo zokwakha, iingubo ezisekelwe emanzini, kunye neepeyinti ze-acrylic resin.
I. Ukuhambelana kweendidi zeSilica kunye neeNkqubo zokuCoating
1. I-Silica efumileyo
Iindawo Zokusetyenziswa: Iingubo ezinyangekayo ze-UV (umz., iingubo zomthi ze-UV, iingubo zeplastiki ze-UV), iingubo zefilimu engqindilili yemizi-mveliso, kunye neengubo zomgubo.
Iingenelo Zokusebenza: I-thixotropy enamandla, imiphumo emihle kakhulu yokulwa nokuwa kunye neyokuthomalalisa.
Impembelelo yeendleko: Nangona ixabiso leyunithi liphezulu, idosi efunekayo iphantsi (0.5%–3%), nto leyo eyenza ukuba iindleko zizonke zilawuleke.
2. I-Silica evuthulukileyo
Iindawo Zokusetyenziswa: Iingubo zoyilo, iingubo zoshishino eziphakathi ukuya kwezisezantsi.
Iingenelo Zokusebenza: Ixabiso liphantsi, nangona kufuneka idosi ephezulu (3%–10%); isiphumo esingcono sokumathisa xa kuthelekiswa ne-fumed silica.
Imida: Ukusasazwa ngokubanzi kobungakanani bamasuntswana, ukuchaneka okuphantsi kulawulo lwe-rheology.
3. I-Silica Airgel
Izicelo ezikhethekileyo: Iingubo ezingatshiyo, iingubo ezikhuselayo zezixhobo ezishushu kakhulu.
Ingxaki yeendleko: Inkqubo yokulungiselela enzima; ixabiso lifikelela kumashumi amawaka e-RMB/kg, ngaloo ndlela lisetyenziswa kuphela kwiindawo ezinexabiso eliphezulu.
II. Ukuphuculwa kokusebenza kokugquma
1. Ukulungiswa kweRheology kunye nokuSebenza kakuhle kweSicelo
I-silica efumileyo yenza isakhiwo senethiwekhi esinemilinganiselo emithathu ngokusebenzisa amaqela e-hydroxyl engaphezulu, nto leyo enika i-thixotropy: phantsi kwamandla okucheba, i-viscosity iyancipha ukuze kube lula ukuyisebenzisa; xa i-static, i-viscosity ibuyela kwimeko yayo ukuze kuthintelwe ukugoba kunye nokwakheka komphetho. I-silica evuthuzayo iphucula uzinzo lwe-coating, ithintela ukuqina kwe-pigment, kwaye yandisa ubomi bokugcina.
2. Ukungabanjwa kweCake kunye nokuPhuculwa kokusasazeka
I-silica ethambileyo kakhulu, njengesithako sangaphandle, ifunxa phezu komphezulu weengubo zomgubo ukuze idale "impembelelo yokuthwala ibhola," iphucula ukuhamba kwamanzi kunye nokumelana nokugaywa. Amandla aphezulu omphezulu we-silica efumileyo anciphisa ixesha lokusasazeka kwaye aphucula ukufana kombala.
3. Uphuculo Lokusebenza
Isiphumo sokuMatana: Ii-microparticles zeSilica zinciphisa ukukhanya ngokusebenzisa ukubonakaliswa okusasazekayo, zifikelela kwi-matte ukuya kwi-semi-matte finishes.
Iimpawu zoomatshini: Iphucula ubulukhuni bokugquma, ukumelana nokukrweleka, kunye nokumelana nemozulu, yandisa ubomi benkonzo.
Iimpawu Zokubona: Iphucula ukusasazeka kwe-UV ukuze ikwazi ukulwa nokwaluphala ngelixa igcina ukukhanya.
4. Imizekelo yesicelo esikhethekileyo
Iingubo ezixineneyo (umz., iipeyinti zaselwandle): Zixhomekeke kwi-silica thixotropy efumileyo ukuqinisekisa ukutyeba kwefilimu.
Iingubo zomgangatho: Ziphucula ukuthambekela kunye nokumelana nokukrwela.
Ukukhetha Uhlobo: Iintlobo ezahlukeneyo ze-silica (ezifumileyo/ezimanzi) kufuneka zikhethwe ngokusekelwe kwiimfuno zokugquma—umzekelo, i-silica efumileyo yokulawula i-rheology ngokuchanekileyo, ngelixa i-silica efumileyo inika ibhalansi engcono yokusebenza kweendleko kwi-matting.
III. Iingcebiso zokulinganisela iindleko kunye nokusebenza
Iingubo ezikumgangatho ophezulu (umz., iingubo zeemoto, iingubo ze-UV): I-silica efumileyo iyathandwa, nangona ixabiso layo liphezulu, njengoko iphucula kakhulu ukusebenza kwayo (umz., ukumelana nokukrweleka kabini).
Iingubo eziphakathi ukuya kwezisezantsi (umz., iingubo zoyilo): I-silica evuthulukileyo inika umlinganiselo ongcono weendleko-ukusebenza, kwaye ukuhambelana kwayo kunokuphuculwa ngokuguqulwa komphezulu.
Iimfuno ezikhethekileyo zokusebenza (ukugquma umlilo/ukugquma ubushushu): I-silica airgel ayinakuthathelwa indawo kodwa ifuna uvavanyo olupheleleyo lokusetyenziswa kakuhle kweendleko.
Isiphelo: Kwishishini lokugquma, i-silica inciphisa iindleko ngokubanzi ngokungathanga ngqo ngokuphucula ukusebenza. Nangona kunjalo, ixabiso lezinto eziluhlaza kunye notyalo-mali lwenkqubo kufuneka zilinganiswe. Ukusetyenziswa okuphezulu kudla ngokusebenzisa i-silica efumileyo, ngelixa iimarike eziphakathi ukuya kwezisezantsi zikhetha i-silica ekhawulezileyo ukuze kusetyenziswe ngcono iindleko.
