Aerogels ane yakanyanya kuderera density, yakakwirira chaiyo nzvimbo uye yakakwirira porosity, iyo inoratidza yakasarudzika optical, thermal, acoustic, uye magetsi zvivakwa, izvo zvichave nehupamhi tarisiro yekushandisa muminda yakawanda.
Fiberglassairgel stitched combo mat inonyanya kuvharidzira zvinhu zvakagadzirwa neairgel uye girazi fiber composite. Haisi kungochengetedza maitiro ehutsika hwekupisa kwe aerogel, asi inewo maitiro ekugadzirisa uye kusimba kwepamusoro-soro, uye iri nyore kuvaka.Kuenzaniswa nemagariro ekugadzirisa zvinhu, girazi fiber airgel inonzwa ine zvakawanda zvakanakira maererano nekupisa kwekushisa, mechanical properties, kudzivirira kwemvura, uye kupisa moto.
Iyo inonyanya kuve nemhedzisiro yemurazvo retardant, kupisa kwemafuta, kupisa kwemafuta, kuvharidzira inzwi, kubatwa nekuvhunduka, etc. Inogona kushandiswa se substrate yekupisa yekupisa yemotokari nyowani simba, mota yemusuwo wepaneru sirin'i zvinhu, yekushongedza kwemukati mahwendefa ekushongedza, kuvaka, indasitiri uye zvimwe zvinopisa zvinopisa, zvinotora ruzha uye kupisa-kupisa zvinhu, girazi regirazi rekuisa zvinhu, girazi regirazi rekuisa zvinhu, girazi regirazi resimbi. etc. Substrate.
Nzira dzekugadzirira SiO₂ airgel composite zvinhu zvinowanzobatanidza in situ method, soaking method, chemical vapor permeation method, molding method, etc. Pakati pavo, in situ nzira uye nzira yekuumba inowanzoshandiswa kugadzirira fiber-reinforced SiO₂ airgel composite materials.
Nzira yekugadzira yefiberglass airgel matkunyanya inosanganisira matanho anotevera:
① Girazi faibha pretreatment: Matanho ekutanga ekuchenesa nekuomesa girazi fiber kuve nechokwadi chemhando uye kuchena kwefiber.
② Kugadzirira kweairgel sol: Matanho ekugadzira airgel sol akafanana neyakajairwa airgel yakanzwa, kureva silicon-yakatorwa makomisheni (senge silica) inosanganiswa nesolvent uye inopisa kuita yunifomu sol.
③ Coating fiber: Girazi fiber jira kana shinda inopinzwa uye yakaputirwa musol, kuitira kuti iyo fiber inosangana zvizere neairgel sol.
④ Gel formation: Mushure mokunge fiber yakaputirwa, inonzi gelatinized.Iyo nzira yegelation inogona kushandisa kupisa, kudzvinyirira, kana kemikari crosslinking agents kuti akurudzire kuumbwa kwejeri yakasimba yeaerogel.
⑤ Kubviswa kwesolvent: Zvakafanana nekugadzirwa kweiyo airgel yakanzwa, iyo gel inoda kuparadzwa kuitira kuti iyo chete yakasimba airgel chimiro chasara mufiber.
⑥ Kupisa kurapwa: Thefiberglass airgel matmushure mekuparadzwa kupisa kunorapwa kuti kuwedzere kugadzikana kwayo uye mechanical properties.The tembiricha uye nguva yekupisa kurapwa inogona kugadziriswa maererano nezvinodiwa chaizvo.
⑦ Kucheka / kuumba: Girazi fiber airgel yakanzwa mushure mekupisa kurapwa inogona kutemwa uye kuumbwa kuti iwane chimiro chinodiwa uye saizi.
⑧ Kurapwa kwepamusoro (kusarudza): Zvinoenderana nezvinodiwa, iyo pamusoro pefiberglass airgel mat inogona kuramba ichirapwa, senge kupfekedza, kufukidza kana kushanda, kusangana nezvinodiwa zvekushandisa.
Nguva yekutumira: Sep-23-2024
