Ama-aerogel anomthamo ophansi kakhulu, indawo ethile ephezulu kanye ne-porosity ephezulu, ebonisa izici eziyingqayizivele zokubuka, ezishisayo, ze-acoustic, nezikagesi, ezizoba nethuba elibanzi lokusetshenziswa emikhakheni eminingi.
I-FiberglassI-airgel ithungelwe i-combo mat ngokuyinhloko iyimpahla yokufakelwa eyenziwe nge-airgel ne-glass fiber composite. Ayigcini nje kuphela izici ze-conductivity ephansi yokushisa ye-aerogel, kodwa futhi inezici zokuguquguquka namandla aphezulu, futhi kulula ukwakha.Uma kuqhathaniswa nezinto zendabuko zokufakelwa, i-glass fiber airgel yazizwa inezinzuzo eziningi mayelana ne-conductivity yokushisa, izakhiwo zemishini, ukumelana kwamanzi, nokumelana nomlilo.
Ikakhulukazi inemiphumela ye-flame retardant, ukwahlukanisa okushisayo, ukwahlukanisa okushisayo, ukwahlukanisa umsindo, ukumuncwa ukushaqeka, njll. Ingasetshenziswa njenge-substrate yokushisa okushisayo kwezimoto ezintsha zamandla, izinto zokwakha zephaneli yomnyango wezimoto, umhlobiso wangaphakathi amapuleti okuhlobisa ayisisekelo, ukwakhiwa, imboni nokunye ukwahlukanisa okushisayo, ukumuncwa komsindo kanye nezinto zokufakelwa ukushisa, ingilazi ye-fiber-insulating materials, i-plastic-insulating materials njll. I-substrate.
Izindlela zokulungiselela ze-SiO₂ i-airgel composite materials ngokuvamile zifaka indlela ye-situ, indlela yokucwilisa, indlela yokufaka umhwamuko wamakhemikhali, indlela yokubumba, njll. Phakathi kwazo, indlela ye-in situ kanye nendlela yokubumba ngokuvamile isetshenziselwa ukulungisa izinto ezihlanganisiwe ze-SiO₂ ze-airgel ze-fiber-reinforced.
Inqubo yokukhiqiza yeI-fiberglass airgel matikakhulukazi kuhlanganisa izinyathelo ezilandelayo:
① I-Glass fiber pretreatment: Izinyathelo zokwelashwa kwangaphambili zokuhlanza nokomisa i-fiber yengilazi ukuqinisekisa ikhwalithi nokuhlanzeka kwefayibha.
② Ukulungiswa kwe-airgel sol: Izinyathelo zokulungiselela i-airgel sol zifana ne-airgel evamile ezwakalayo, okungukuthi izinhlanganisela ezithathwe ku-silicon (njenge-silica) zixutshwe ne-solvent bese zishiswa ukuze zenze i-sol efanayo.
③ I-coating fibre: Indwangu ye-fiber yengilazi noma intambo ifakwe futhi iboshwe ku-sol, ukuze i-fiber ixhumane ngokugcwele ne-airgel sol.
④ Ukwakhiwa kwejeli: Ngemva kokuba i-fiber iboshwe, i-gelatinized.Indlela ye-gelation ingasebenzisa ukushisa, ukucindezelwa, noma ama-agent amakhemikhali e-crosslinking ukukhuthaza ukwakheka kwesakhiwo sejeli esiqinile se-aerogel.
⑤ Ukususwa kwe-solvent: Ngokufanayo nenqubo yokukhiqiza ye-airgel ejwayelekile, ijeli idinga ukuchithwa ukuze kusele isakhiwo esiqinile se-airgel kuphela ku-fiber.
⑥ Ukwelashwa kokushisa: II-fiberglass airgel matemva kokuchithwa kuphathwa ukushisa ukuze kuthuthukiswe ukuzinza kwayo kanye nezakhiwo zemishini.Izinga lokushisa kanye nesikhathi sokwelashwa kokushisa kungalungiswa ngokuvumelana nezidingo ezithile.
⑦ Ukusika/ukwenza: I-airgel ye-glass fibre ezwakala ngemva kokwelashwa kokushisa ingasikwa futhi yakheke ukuze kutholwe umumo nosayizi oyifunayo.
⑧ Ukwelashwa okungaphezulu (ongakukhetha): Ngokwezidingo, ingaphezulu le-fiberglass airgel mat lingaqhubeka nokwelashwa, njengokumboza, ukumboza noma ukusebenza kahle, ukuze kuhlangatshezwane nezidingo ezithile zohlelo lokusebenza.
