Njengoba imithetho yokuphepha komlilo emhlabeni wonke iya ngokuya iba nzima futhi isidingo sengilazi yezinga eliphezulu yezakhiwo evikelwe emlilweni siqhubeka sikhula, abakhiqizi baphendukela ezintweni ezikhethekile ezithuthukisiwe ukuze bakhulise ukuqina komkhiqizo, ukusebenza kwezinga lokuvikela ukushisa kanye nokungaguquguquki kokubona. Phakathi kwalezi zinto, i-fumed silica yezinga lezimboni isiphenduke into ebalulekile yokuthuthukisa ukusebenza ethuthukisa kokubili ukusebenziseka kokukhiqiza kanye nokuthembeka komkhiqizo wokugcina wezinhlelo zengilazi evikelwe emlilweni.

Ikhiqizwa nge-high-temperature flame hydrolysis, i-high-purity amorphous fumed silica inemisebenzi eminingi engathathelwa indawo ku-inorganic fire gel interlayer — ingxenye eyisisekelo yokuvikela ukushisa yengilazi yezinga A evikelwe emlilweni egcwalisiwe.

Okokuqala, inikeza ukulawulwa okunembile kwe-rheological. Isakhiwo sayo esiyingqayizivele senethiwekhi yezinhlangothi ezintathu ze-nano-scale sinikeza izakhiwo zokuncipha kwe-shear kumafomula ejeli lomlilo. Ngesikhathi sokukhiqizwa kwe-vacuum infusion, ijeli igcina i-viscosity ephansi ukuze kuthululwe kahle ngaphandle kwamabhamu; lapho iphumule, inikeza amandla anele okuqinisa ukuvimbela ukuhlehla kwezinto zokugcwalisa kanye nokuhlukaniswa kwezendlalelo, okuqinisekisa ukuzinza kokugcinwa isikhathi eside.

Okwesibili, iqinisa isakhiwo se-high-temperature thermal barrier. Lapho ibhekene nezimo zomlilo, i-fumed silica ibamba iqhaza ekuphenduleni kwe-sintering ye-silica matrix ukuze yakhe i-ceramic skeleton ekhuluphele kakhulu, elinganayo futhi enezimbobo. Lesi sakhiwo sehlisa i-thermal conductivity, sithuthukisa ubuqotho besakhiwo se-high-temperature, futhi sibopha izingcezu zengilazi eziqhekekile ngokuqinile ukuze kugcinwe ukuphelela kwe-fire barrier futhi kuvinjwe ukungena kwelangabi nentuthu.

Okwesithathu, kuthuthukisa ukuzinza kokukhanya nokuhamba kwesikhathi. I-fumed silica ephezulu yokuhlanzeka enobukhulu bezinhlayiyana ezilawulwayo ithuthukisa ukucaca kwengxenye ye-fire gel ephakathi, yehlisa i-haze, futhi imelana nokuphuzi kanye ne-alkali efflorescence ngaphansi kokuchayeka isikhathi eside kwe-UV kanye nesimo sezulu sangaphandle.

I-fumed silica yamukelwa kabanzi ekukhiqizeni imikhiqizo yengilazi evimbela umlilo yezinga eliphezulu, okuhlanganisa ingilazi evimbela umlilo ye-Class A insulated grouted yezindonga zangaphandle zezakhiwo, ingilazi evimbela umlilo ye-high borosilicate yezakhiwo eziphakeme nezindawo zezimboni, izihlukanisi zengilazi ezivimbela umlilo zezikhungo zedatha nezakhiwo ezinkulu zezentengiselwano, kanye nengilazi evimbela umlilo emise okukhethekile yamaphrojekthi amakhulu ezakhiwo.

Njengoba imboni yezinto zokuvikela umlilo yomhlaba wonke iqhubeka nokuthuthuka, i-fumed silica yezinga lezimboni yekhwalithi ephezulu izohlala iyinto eyisisekelo esemqoka ekuthuthukiseni ukusebenza kwengilazi evimbela umlilo. Kubakhiqizi bengilazi, ukukhetha i-fumed silica enosayizi wezinhlayiya ongaguquki, ukuhlanzeka okuphezulu kanye nekhwalithi ezinzile kuyisinyathelo esibalulekile sokuthuthukisa ukuncintisana komkhiqizo nokuhlangabezana nezidingo eziqinile zokuphepha komlilo zamazwe ngamazwe.
