Malingana ndi makina opangira kutentha, nsalu yotchinga kutentha imatha kugawidwa m'magulu atatu: chotchinga, mtundu wonyezimira ndi mtundu wa radiation.ife Suzhou supxtech kampani akhoza kupereka luso ❖ kuyanika Airgel ndi makina, zikhoza kugwiritsidwa ntchito kwa colth, pepala pulasitiki ndi anamva.imagwiritsa ntchito kwambiri malo ofunda.

Chotchinga chotchinga chotchinga kutentha ndi mtundu wa zokutira zoziziritsa zomwe zimazindikira kutsekereza kutentha kudzera muzoletsa za kusamutsa kutentha.The kutentha kutchinjiriza limagwirira ndi yosavuta, ndi zikuchokera ndi otsika matenthedwe madutsidwe kapena mpweya ndi otsika kwambiri matenthedwe madutsidwe madutsidwe anayambitsa mu filimu kupeza zabwino kutentha kutchinjiriza kwenikweni.Nthawi zambiri amakhala ndi mawonekedwe ang'onoang'ono kachulukidwe kachulukidwe kakang'ono, kachulukidwe kakang'ono kazakudya komanso kachulukidwe kakang'ono ka dielectric.

Chophimba chonyezimira chotenthetsera kutentha ndikulekanitsa mphamvu ya dzuwa mwa mawonekedwe owunikira.Zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizira ufa wa ceramic, ufa wa aluminiyamu, titaniyamu woipa ndi ATO (antimony doped tin dioxide) ufa.

Common chotchinga nsalu kutentha kutchinjiriza ❖ kuyanika wothandizila malinga ndi kapangidwe mankhwala, makamaka polyvinyl kolorayidi (PVC), polyacrylate (PA), polyurethane (PU), silikoni, mphira emulsion ndi polytetrafluoroethylene, pakati PA ndi PU ntchito kwambiri;Malinga ndi ntchito sing'anga, akhoza kugawidwa mu zosungunulira ndi madzi omwazika mtundu 2.

SiO2 airgel ndi amorphous nanoporous zakuthupi ndi dongosolo controllable ndi mosalekeza atatu azithunzithunzi maukonde dongosolo.Ndipo kachulukidwe kake ndi kosinthika pakati pa 3 ~ 500mg/cm3, ndi kachulukidwe otsika kwambiri padziko lonse lapansi wa zinthu zolimba, porosity imatha kufika 80% ~ 99.8%, pore kukula pakati pa 1 ~ 100nm, malo enieni amatha kukhala mpaka 1000m2/g.Chifukwa cha mawonekedwe ake apadera a nanoporous, matenthedwe ake otenthetsera amakhala otsika kwambiri, otsika ngati 0.017W/ (m•K) kutentha ndi kupanikizika, zomwe zimapangitsa kukhala chinthu chotsika kwambiri chodziwika bwino chokhala ndi matenthedwe amafuta.Chifukwa gulu la mafupa a airgel ndi laling'ono kuposa kutalika kwa kuwala kowoneka, limakhalanso ndi ntchito yabwino yotumizira kuwala.Pa nthawi yomweyo, ndi inorganic zakuthupi, ndi sanali kuyaka kapena lawi retardant kwenikweni, m'munda wa kutchinjiriza matenthedwe ali osiyanasiyana chiyembekezo ntchito.
