E like me ke ʻano o ka wela wela, hiki ke hoʻokaʻawale ʻia ka uhi wela wela i ʻekolu ʻano: ʻano pale, ʻano noʻonoʻo a me ke ʻano radiation.Hiki iā mākou ka hui ʻo suzhou supxtech ke hāʻawi i ka ʻenehana hoʻopili ʻo Airgel a me nā mīkini, hiki ke hoʻohana ʻia no ka colth, ka pepa plastik a me ka manaʻo.hoohana nui ia no ka wahi mehana.

ʻO ka uhi ʻana i ka wela wela ke ʻano o ka uhi hoʻoluʻu passive e ʻike i ka hoʻokaʻawale wela ma o ka hopena impedance o ka hoʻoili wela.He mea maʻalahi ke ʻano o ka wela wela, a ua hoʻokomo ʻia ke ʻano me ka conductivity thermal haʻahaʻa a i ʻole ka ea me ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa i loko o ke kiʻiʻoniʻoni e loaʻa ai ka hopena insulation wela maikaʻi.Loaʻa iā ia nā hiʻohiʻona o ka puʻupuʻu puʻupuʻu liʻiliʻi, haʻahaʻa thermal conductivity a me ka liʻiliʻi dielectric mau.

ʻO ka uhi ʻana i ka wela wela e hoʻokaʻawale i ka ikehu o ka lā ma ke ʻano o ka noʻonoʻo.ʻO nā mea hoʻomanaʻo maʻamau i hoʻohana ʻia me ka pauka ceramic, ka pauka aluminika, ka titanium dioxide a me ka pauka ATO (antimony doped tin dioxide).

ʻO ka mea pale maʻamau ka lole pale wela e like me ka hoʻolālā kemika, ka nui o ka polyvinyl chloride (PVC), polyacrylate (PA), polyurethane (PU), silicone, rubber emulsion a me polytetrafluoroethylene, ma waena o ka PA a me ka PU i hoʻohana nui ʻia;E like me ka hoʻohana ʻana i ka medium, hiki ke hoʻokaʻawale ʻia i ka solvent a me ka wai i hoʻopuehu ʻia i ke ʻano 2.

ʻO SiO2 airgel kahi mea nanoporous amorphous me ka hoʻolālā hiki ke hoʻopaʻa ʻia a me ka hoʻomau ʻana o ka ʻoihana pūnaewele ʻekolu-dimensional.A hiki ke hoʻololi ʻia kona density ma waena o 3 ~ 500mg/cm3, ʻo ia ka haʻahaʻa haʻahaʻa loa o ka honua o kahi mea paʻa, hiki i ka porosity ke hiki i 80% ~ 99.8%, ka nui o ka pore ma waena o 1 ~ 100nm, kahi kikoʻī kikoʻī hiki ke piʻi i 1000m2/g.Ma muli o kona ʻano nanoporous kū hoʻokahi, he haʻahaʻa loa kona conductivity wela, e like me ka haʻahaʻa e like me ka 0.017W/ (m•K) ma ka lumi wela a me ke kaomi, e lilo ia i mea paʻa haʻahaʻa loa me ka conductivity thermal.No ka mea ʻoi aku ka liʻiliʻi o ka ʻāpana o ka ʻiʻo airgel ma mua o ka lōʻihi o ka nalu o ke kukui ʻike ʻia, ʻoi aku ka maikaʻi o ka lawe ʻana i ka māmā.I ka manawa like, he ʻano mea inorganic, me ka hopena non-combustible a i ʻole ka lapalapa ahi, ma ke kahua o ka thermal insulation he ākea ka nui o nā noi.
