Imikhiqizo yokumboza i-Airgel Thermal
Imikhiqizo yokumboza ye-Airgel Thermal,
I-Airgel enamathela efudumele,
Izici Zokusebenza
1. Ukumelana nokushisa okuphezulu kwe-Adiabatic
I-thermal conductivity ephansi, umkhiqizo ojwayelekile we-thermal conductivity 0.018~0.020 W/(m•K), ophansi kakhulu ukuya ku-0.014 W/(m•K), isigaba sokushisa siphansi kunemikhiqizo yontanga, esiphezulu singakwazi ukumelana no-1100℃ izinga lokushisa eliphezulu, ukushisa ukulondolozwa kanye nomphumela wokwahlukanisa izikhathi ezingu-3-5 zezinto zendabuko, ukusebenza kahle okuphezulu nokonga amandla.
2. Ingangeni manzi futhi iyaphefumula
Ngokusebenza okuhle kakhulu kokuvikela amanzi, izinga le-hydrophobic ≥99%, ukuhlukaniswa kwamanzi awuketshezi, nokuvumela umhwamuko ukuthi udlule.
3. Umlilo futhi ongashi
Ithole ibanga elingu-A1 eliphakeme kunawo wonke ezingeni lebanga lokuvutha kwezakhiwo kanye nebanga elingu-A eliphakeme kakhulu elingashi ebangeni lezinto ezivuthayo zangaphakathi zezimoto.
4. Ukuphepha kanye nokuvikelwa kwemvelo
Imikhiqizo idlulile ku-RoHS, ukutholwa kwe-REACH, akuqukethe izinto eziyingozi emzimbeni womuntu, okuqukethwe kwe-chloride encibilikayo kuncane kakhulu.
5. Ukumelana nokuqina nokucindezela, ukwakhiwa okulula nokuhamba
Ukuvumelana nezimo okuhle namandla aqinile/acindezelayo, ukusetshenziswa kwesikhathi eside kokungaxazululi, akukho ukuguquguquka;Ukukhanya futhi kulula, ukusika kulula, ukusebenza kahle kokwakhiwa okuphezulu, kufanelekile izidingo ezihlukahlukene zomumo oyinkimbinkimbi, izindleko zokuthutha eziphansi.
Isicelo
Emkhakheni wezimboni
Isitoreji samandla kagesi, imboni ye-petrochemical, izimboni zezimboni kanye nezinye izimboni ezidinga ukufakwa kwamapayipi noma izingxenye zokufakwa kwesithando somlilo zidinga ukusebenzisa izinto ezigcina ukushisa kahle kakhulu, izinto zokufakelwa kwe-airgel zinganciphisa ngempumelelo ukulahlekelwa ukushisa futhi zonge amandla okushisa, zithuthukise ukusebenza kahle kokushisa. umthombo, umphumela wokufaka ukushisa uyinto yendabuko izikhathi ezi-3 ~ 5, nempilo ende.
Endimeni ye-aerospace
I-Airgel thermal insulation material ingasetshenziswa njengezinto zokushisa ezishisayo zendlu yezindiza, ezingathuthukisa umphumela wokushisa oshisayo, ukunciphisa izinga lokushisa le-cabin, ukunciphisa ngempumelelo inani le-thermal insulation material, ukwandisa isikhala sokusebenzisa ekamelweni, futhi kuthuthukise ngempumelelo ezihlukahlukene. izindawo zokusebenza.I-Airgel thermal insulation material ingafinyelela umphumela ongcono wokushisa oshisayo ngesisindo esilula kanye nevolumu encane, enezinzuzo ezinhle emkhakheni wezokundiza kanye nezicelo ze-aerospace.
Emkhakheni wokwakha
Ngokuthuthuka okuqhubekayo kwezidingo zikazwelonke zokongiwa kwamandla kanye nokunciphisa ukungcola, kanye nokuphishekela kwabantu izinga lempilo, ukwahlukanisa izakhiwo sekuphenduke isihloko esibalulekile kancane kancane emkhakheni wokwakha.Ukuze isakhiwo, cishe zonke izingxenye, zihilelekile esidingweni sokushisa okushisayo, ikakhulukazi ekwakhiweni kodonga lwesakhiwo, ukufakwa kwe-roof floor.I-silica airgel ingakwazi ukumelana nokushisa okuphezulu, ngokuvamile ku-800 ℃, ukwakheka kwayo, ukusebenza akunanguquko esobala, iphephile, yonga amandla, ivikela imvelo yezinto eziphezulu zokufakelwa.
Emkhakheni wezokuthutha
Ukusebenza kokufakwa kokushisa kophahla lwemoto kungenye yezinto eziyinhloko ezithinta ukudluliswa kokushisa komzimba wemoto.Kubaluleke kakhulu ekuhlaziyeni ukusetshenziswa kwamandla okusebenza kwemoto, ukunquma umthwalo wayo wesimo somoya, ukugwema ukuvela kwezimo ezimbi zokusebenza, nokugcina indawo eshisayo ekhululekile ngaphakathi kwemoto.Emkhakheni wezimoto zamandla amasha, umlilo wemoto kagesi kanye nezingozi zokuqhuma okubangelwa ibhethri ye-lithium ion "i-thermal runaway" ibikwe kaningi.Ukuqinisekisa kanjani ngokuphumelelayo ukushabalaliswa kokushisa nokuphepha kwebhethri ye-lithium sekuphenduke "inkemba ye-Damocles" ilenga phezu kwekhanda lezimboni zezimoto kanye namabhizinisi ebhethri lamandla.I-Nanoporous airgel composite insulation materials isetshenziswe ezitimeleni ezinesivinini esikhulu, endizeni yasekhaya yabagibeli i-C919, nasezimotweni zamandla amasha, okugxile kakhulu ekushiseni kokushisa kwezimoto zokuhamba kanye nokuvikelwa kwamabhethri e-lithium ezimotweni zamandla amasha.
Ukucaciswa
Ngokuvumelana nokukhethwa kwe-substrate ehlukene, i-airgel mat ingakhetha uchungechunge oluyinhlanganisela oluhlukene ngokuya ngezidingo ezihlukene zamakhasimende kanye nezimo.Njengamanje, kukhona ikakhulukazi uchungechunge olune lwama-aerogel enziwe ngengilazi (HHA-GZ), i-preoxygenated wire fibre composite aerogels (HHA-YYZ), ama-aerogels ahlanganiswe ne-silicon oxygen fiber composite (HHA-HGZ) kanye nama-aerogel e-ceramic fiber composite (HHA-TCZ ).Amapharamitha wokucaciswa ami kanje:
Ngokusho komshini wokushisa ukushisa, ukufakwa kwendwangu yokushisa ukushisa kungahlukaniswa ngezinhlobo ezintathu: uhlobo lokuvimbela, uhlobo lokubonisa kanye nohlobo lwemisebe.thina Suzhou supxtech singanikela ngobuchwepheshe be-Airgel coating.ingasetshenziselwa kabanzi indwangu neshidi kanye nenani elizwakalayo lendawo .
I-Barrier insulation insulation coating iwuhlobo lokupholisa olwenziwayo olubona ukufakwa kokushisa ngomphumela ovimbelayo wokudluliswa kokushisa.Umshini wokushisa ukushisa ulula, futhi ukubunjwa okune-conductivity ephansi yokushisa noma umoya ophansi kakhulu we-thermal conductivity ungeniswa kwifilimu ukuze uthole umphumela omuhle wokushisa ukushisa.Ngokuvamile inezici zokuminyana kwenqwaba encane, ukuhanjiswa kwe-thermal okuphansi kanye ne-dielectric encane engaguquki.
I-reflective heat insulation coating iwukuhlukanisa amandla elanga ngendlela yokubonisa.Izinto ezivezwayo ezivame ukusetshenziswa zifaka impushana ye-ceramic, i-aluminium powder, i-titanium dioxide kanye ne-ATO (i-antimony doped tin dioxide) powder.
I-agent evamile yokuvimbela ukushisa kwendwangu yokushisa ukushisa ngokusho kwesakhiwo samakhemikhali, ikakhulukazi i-polyvinyl chloride (PVC), i-polyacrylate (PA), i-polyurethane (PU), i-silicone, i-emulsion yerabha kanye ne-polytetrafluoroethylene, phakathi kwayo i-PA ne-PU esetshenziswa kakhulu;Ngokusebenzisa okuphakathi, ingahlukaniswa ibe yi-solvent namanzi ahlakazekile uhlobo 2.
I-SiO2 airgel iyimpahla e-amorphous nanoporous enesakhiwo esilawulekayo kanye nesakhiwo senethiwekhi esinezinhlangothi ezintathu esiqhubekayo.Futhi ukuminyana kwayo kuyalungiseka phakathi kuka-3 ~ 500mg/cm3, kuwukuminyana okuphansi kakhulu komhlaba kwezinto eziqinile, i-porosity ingafinyelela ku-80% ~ 99.8%, usayizi wembotshana ophakathi kuka-1 ~ 100nm, indawo ethile engaphezulu ingaba ngu-1000m2/g.Ngenxa yesakhiwo sayo esiyingqayizivele se-nanoporous, ukusebenza kwayo okushisayo kuphansi kakhulu, kuze kufike ku-0.017W/ (m•K) ekamelweni lokushisa nokucindezela, okuyenza ibe into ephansi eyaziwayo eqinile ene-thermal conductivity.Ngenxa yokuthi iyunithi yesakhiwo ye-airgel skeleton incane kunobude begagasi bokukhanya okubonakalayo, futhi inokusebenza okuhle kokudlulisa ukukhanya.Ngesikhathi esifanayo, i-inorganic material, enomphumela ongashi noma we-flame retardant, emkhakheni we-thermal insulation inezinhlobonhlobo zamathemba okufaka isicelo.
