Iimveliso zokugquma i-Airgel Thermal,
Airgel ukutyabeka efudumeleyo,
Iimpawu zokuSebenza
1. Ukumelana nobushushu obuphezulu be-Adiabatic
I-conductivity ephantsi ye-thermal, imveliso eqhelekileyo ye-thermal conductivity 0.018 ~ 0.020 W / (m• K), ephantsi ukuya kwi-0.014 W / (m• K), icandelo lobushushu lingaphantsi kweemveliso zentanga, i-higher inokumelana ne-1100 ℃ ubushushu obuphezulu, ubushushu. ukugcinwa kunye nefuthe lokufaka i-insulation ngamaxesha angama-3-5 ezinto zemveli, ukusebenza kakuhle kunye nokugcinwa kwamandla.
2. Ukungangeni kwamanzi kunye nokuphefumla
Ngomsebenzi ogqwesileyo ogqwesileyo wokungangeni manzi, izinga le-hydrophobic ≥99%, ukwahlukaniswa kwamanzi angamalwelo, kunye nokuvumela umphunga wamanzi udlule.
3. Umlilo kunye nokungatsha
Ifikelele elona bakala liphezulu le-A1 kumgangatho webakala lokutsha kwesakhiwo kunye nelona bakala liphezulu A elingenakutsha kwibakala lokutsha kwezinto zangaphakathi zeemoto.
4. Ukhuseleko kunye nokukhuselwa kwendalo
Iimveliso zidlulile i-RoHS, i-REACH ifunyenwe, ayinayo izinto ezinobungozi kumzimba womntu, umxholo we-chloride onyibilikayo uncinci kakhulu.
5. Ukunyanzeliswa kunye nokuxhatshazwa koxinzelelo, ukwakhiwa okufanelekileyo kunye nokuthutha
Ukuguquguquka okuhle kunye nokuqina / amandla oxinzelelo, ukusetyenziswa kwexesha elide lokungahlali, akukho kuguqulwa;Ukukhanya kunye nokulungeleka, kulula ukusika, ukusebenza kakuhle kolwakhiwo, kufanelekile kwiimfuno ezahlukeneyo zemilo enzima, iindleko zokuthutha eziphantsi.
Isicelo
Kwintsimi yezoshishino
Ugcino lwamandla ombane, imveliso yepetrochemical, iikhilni zemizi mveliso kunye namanye amashishini afuna ukugqunywa kwemibhobho okanye iindawo zokugquma iziko kufuneka zisebenzise izinto eziphezulu zokugcina ubushushu, imathiriyeli yokugquma i-airgel inokunciphisa ngokufanelekileyo ilahleko yobushushu kunye nokugcina amandla obushushu, ukuphucula ukusebenza kakuhle kobushushu. umthombo, impembelelo yokufakelwa kobushushu yinto yemveli 3 ~ 5 amaxesha, kunye nobomi obude.
Kwibala le-aerospace
I-Airgel i-thermal insulation imathiriyeli ingasetyenziswa njengesixhobo sokufakelwa kwe-thermal ye-cabin yenqwelomoya, enokuphucula i-thermal insulation effect, ukunciphisa ubushushu bekhabhinethi, ukunciphisa ngokufanelekileyo inani le-thermal insulation material, ukwandisa indawo yokusetyenziswa kwikhabhathi, kunye nokuphucula ngokufanelekileyo iindidi ezahlukeneyo. iindawo zokusebenza.I-Airgel i-thermal insulation material inokufezekisa i-thermal insulation isiphumo esingcono kunye nobunzima obulula kunye nevolumu encinci, enenzuzo enkulu kwintsimi ye-aviation kunye nezicelo ze-aerospace.
Kwintsimi yokwakha
Ngokuphuculwa okuqhubekayo kweemfuno zelizwe zokugcinwa kwamandla kunye nokunciphisa ukukhutshwa kwamandla, kunye nokuphishekela kwabantu umgangatho wobomi, ukugquma kwesakhiwo kuye kwaba yinto ephambili kwintsimi yokwakha.Kwisakhiwo, phantse zonke iinxalenye, zibandakanyeka kwisidingo sokufakelwa kwe-thermal, ngokukodwa kwi-insulation wall insulation, uphahla lwe-roofing floor.I-Silica airgel inokumelana nobushushu obuphezulu, ngokubanzi kwi-800 ℃, ubume bayo, ukusebenza akukho tshintsho lucacileyo, lukhuselekile, lugcina amandla, ukhuseleko lokusingqongileyo lwezinto eziphezulu zokugquma.
Kwintsimi yezothutho
Ukusebenza kokushisa ubushushu bophahla lwesithuthi yenye yezinto eziphambili ezichaphazela ukuhanjiswa kobushushu bomzimba wesithuthi.Kubaluleke kakhulu ukuhlalutya ukusetyenziswa kwamandla okusebenza kwesithuthi, ukugqiba umthwalo we-air conditioning, ukuphepha ukwenzeka kweemeko ezimbi zokusebenza, kunye nokugcina indawo epholileyo yokufudumala ngaphakathi kwesithuthi.Kwintsimi yezithuthi zamandla amatsha, umlilo wemoto yombane kunye neengozi eziqhumayo ezibangelwa ibhetri ye-lithium ion "i-thermal runaway" ixelwe rhoqo.Indlela yokuqinisekisa ngokufanelekileyo ukutshatyalaliswa kobushushu kunye nokukhuseleka kwebhetri ye-lithium ibe "ikrele leDamocles" elixhonywe phezu kwentloko yeefektri zemoto kunye namashishini ebhetri yamandla.I-Nanoporous airgel composite insulation materials isetyenziswe koololiwe abahamba ngesantya esiphezulu, inqwelomoya yasekhaya iC919 yabakhweli, kunye nezithuthi zamandla amatsha, ikakhulu zijolise kubushushu bezithuthi zothutho kunye nokukhuselwa kweebhetri ze-lithium kwizithuthi zamandla amatsha.
Inkcazo
Ngokokhetho lwe-substrate eyahlukileyo, i-airgel mat inokukhetha uthotho olwahlukileyo oludibeneyo ngokweemfuno ezahlukeneyo zabathengi kunye neemeko.Okwangoku, kukho ii-aerogels ezine zeglasi ezine-fiber composite (HHA-GZ), i-preoxygenated wire fiber composite aerogels (HHA-YYZ), i-silicon ephezulu ye-oxygen fiber composite aerogels (HHA-HGZ) kunye ne-ceramic fibre composite aerogels (HHA-TCZ) ).Iiparamitha zokuchaza zimi ngolu hlobo lulandelayo:
Ngokwendlela yokugquma ubushushu, ilaphu lokugquma ubushushu linokwahlulwa libe ziindidi ezintathu: uhlobo lomqobo, uhlobo lokubonisa kunye nohlobo lwemitha.thina iSuzhou supxtech sinokubonelela ngetekhnoloji yokwaleka ye-Airgel.inokusetyenziswa ngokubanzi kwilaphu kunye neshiti kunye nexabiso eliphezulu elivakalayo.
Umqobo wokugquma ubushushu luhlobo oluthile lokupholisa okupholisayo oluqaphela ukugqunywa kobushushu ngempembelelo yokuthintela ukudluliselwa kobushushu.Isixhobo sokufakelwa kobushushu silula, kwaye ukubunjwa okune-conductivity ephantsi ye-thermal okanye umoya ophantsi kakhulu we-thermal conductivity ungeniswa kwifilimu ukuze ufumane isiphumo esihle sokufudumala ukushisa.Ngokuqhelekileyo ineempawu zokuxinana kwe-bulk encinci, i-conductivity ephantsi ye-thermal kunye ne-dielectric encinci.
I-Reflective heat insulation coating kukwahlula amandla elanga ngendlela yokubonakalisa.Izinto eziqhelekileyo ezisetyenziselwa ukubonakalisa ziquka umgubo weceramic, umgubo we-aluminium, i-titanium dioxide kunye ne-ATO (i-antimony doped tin dioxide) umgubo.
Umqobo oqhelekileyo welaphu lokugquma ubushushu be-agent ngokuhambelana nesakhiwo sekhemikhali, ikakhulu ibandakanya i-polyvinyl chloride (PVC), i-polyacrylate (PA), i-polyurethane (PU), i-silicone, i-emulsion yerabha kunye ne-polytetrafluoroethylene, phakathi kwayo i-PA kunye ne-PU zisetyenziswa kakhulu;Ngokusetyenziswa kwe-medium, inokwahlulwa ibe yi-solvent kunye namanzi asasazwe ngohlobo lwe-2.
I-SiO2 i-airgel yimpahla ye-amorphous nanoporous enesakhiwo esilawulwayo kunye nesakhiwo esiqhubekayo se-network-dimensional network.Kwaye ukuxinana kwayo kulungelelaniswa phakathi kwe-3 ~ 500mg / cm3, yeyona nto iphantsi kwehlabathi yezinto eziqinileyo, i-porosity inokufikelela kwi-80% ~ 99.8%, ubukhulu be-pore phakathi kwe-1 ~ 100nm, indawo ethile yendawo ingafikelela kwi-1000m2 / g.Ngenxa yolwakhiwo olukhethekileyo lwe-nanoporous, i-thermal conductivity yayo iphantsi kakhulu, iphantsi njenge-0.017W/ (m•K) kwiqondo lobushushu begumbi kunye noxinzelelo, iyenza ibe yeyona nto iphantsi eyaziwayo eqinileyo ene-thermal conductivity.Ngenxa yokuba iyunithi yolwakhiwo lwe-airgel skeleton incinci kunobude bokukhanya okubonakalayo, ikwanokuhanjiswa kokukhanya okulungileyo.Ngexesha elifanayo, liyi-inorganic material, enefuthe elingenakutsha okanye elivuthayo, kwintsimi ye-thermal insulation inoluhlu olubanzi lwamathemba okusebenza.
