Silica Airgel Supplier

Amadziwika chifukwa cha zinthu zake zabwino kwambiri zotsekera matenthedwe, silica airgel ndi lotseguka, porous, zokonzedwa bwino, opepuka, hydrophobic synthetic amorphous silica. Mapangidwe ake amachepetsa njira yaulere ya mpweya, potero kuchepetsa matenthedwe madutsidwe ake. Komanso ndi kwambiri pothamangitsa madzi ndi nthunzi permeable. Choncho angagwiritsidwe ntchito pomanga ntchito kupereka kasamalidwe ndi kulamulira chinyezi.

Ma silika aerogels amapangidwa ndi njira ya sol-gel pogwiritsa ntchito zoyambira zotsika mtengo za alkoxide monga TEOS kapena TMOS kapena silicic acid yosungunuka m'madzi. (Na2SiO3). Kuchuluka kwa ma gelation awa kumatha kuyambitsidwa ndi kuwonjezeka kwa kutentha, kusintha pH, adsorption kapena ma radiation-induced nucleation. Ma silika aerogels amadziwika ndi malo awo okwera kwambiri kuyambira mmwamba mpaka 1000 m2 g1). Maonekedwe awo ndi amorphous, sanali crystalline, ndi kukhala ndi kuwonekera kwapamwamba komanso index yotsika ya refractive. Ma doping a ma aerogel okhala ndi ma transition metal oxides ngati vanadia amabweretsa zothandizira bwino.[1]

Komanso, amawonetsa zinthu zosangalatsa monga kusinthasintha kwakukulu komanso kutha kubwezeretsa mawonekedwe pambuyo potsitsa. Pachifukwa ichi, ndi okongola kwa ntchito zambiri. Pofuna kuyesa katundu wawo makina, mndandanda wa zitsanzo anapangidwa mwa kusakaniza ndende zosiyanasiyana (5 wt% ndi 10 wt%) ya silica airgel yokhala ndi mphira wobwezerezedwanso ndi PVB. Zophatikizika izi zidayesedwa kupsinjika-kupsinjika pa Carver laboratory hydraulic press.. Makhalidwe omwe adabwezedwa a Young's modulus a zitsanzo adachokera 69-98 Pa, kusonyeza elasticity yawo yabwino. Komanso, zitsanzo zonse anasonyeza kukhoza kwambiri kuyamwa organic zamadzimadzi.
