Airgel Thermal insulator yekuputira zvigadzirwa
Isu tinochengeta zviri nani uye kunatsa zvinhu zvedu zvekutengesa uye sevhisi.Panguva imwecheteyo, isu tinoita basa racho nekushingairira kuita tsvakiridzo nekuvandudza kweAirgel Thermal insulator yekuisa zvigadzirwa, Kubva pakavambwa mukutanga 1990s, isu takagadzira yedu yekutengesa network muUSA, Germany, Asia, uye akati wandei Middle East nyika.Isu tinovavarira kuve wepamusoro kirasi mutengesi weOEM yepasirese uye aftermarket!
Isu tinochengeta zviri nani uye kunatsa zvinhu zvedu zvekutengesa uye sevhisi.Panguva imwecheteyo, tinoita basa racho nekushingaira kuita tsvakurudzo nekuvandudzakupfeka fibic sio2, Hatizongoenderera mberi tichiunza hutungamiri hwehunyanzvi hwenyanzvi kubva kumba nekune dzimwe nyika, asi zvakare kugadzira zvigadzirwa zvitsva uye zvepamberi nguva dzose kuti zvizadzise zvinogutsa zvinodiwa nevatengi vedu pasi rese.
Maitiro Ekuita
1. Adiabatic high temperature resistance
Low thermal conductivity, yakajairika chigadzirwa thermal conductivity 0.018 ~ 0.020 W/(m•K), yakaderera kusvika 0.014 W/(m•K), tembiricha chikamu chakaderera pane vezera zvigadzirwa, yepamusoro-soro inogona kumira 1100 ℃ yakakwirira tembiricha, kupisa. kuchengetedza uye kupinza mhedzisiro ndeye 3-5 nguva dzechinyakare zvinhu, kushanda kwakanyanya uye kuchengetedza simba.
2. Mvura uye inofema
Nekuita kwakanakisa kwese kusapinda mvura, hydrophobic mwero ≥99%, kuparadzaniswa kwemvura yemvura, uye kubvumira mhute yemvura kuburikidza.
3. Moto uye usingabatike
Iyo yakawana iyo yepamusoro giredhi A1 muchivako chekupisa giredhi chiyero uye chepamusoro giredhi A isingabatike mumotokari yemukati zvinhu zvinopisa giredhi.
4. Kuchengetedza uye kuchengetedzwa kwezvakatipoteredza
Zvigadzirwa zvakapfuura RoHS, REACH kuona, haina zvinhu zvinokuvadza kumuviri wemunhu, soluble chloride yemukati idiki kwazvo.
5. Tensile uye compressive kuramba, nyore kuvaka uye kutakura
Kuchinja kwakanaka uye kusimba / kudzvinyirira simba, kushandiswa kwenguva refu kwekusagadzikana, hapana deformation;Chiedza uye chakanakira, chiri nyore kucheka, kushanda kwekuvaka kwakanyanya, kwakakodzera kune dzakasiyana siyana dzakaoma chimiro zvinodiwa, yakaderera mutengo wekufambisa.
Application
Mumunda wemaindasitiri
Iwo emagetsi ekuchengetedza simba, petrochemical indasitiri, maindasitiri kilns uye mamwe maindasitiri anoda kuvharirwa kwepombi kana simbi yekuvharisa zvikamu zvinodiwa kushandisa yakanyanya kunaka kuchengetedza kupisa, airgel insulation zvinhu zvinogona kunyatso kudzikisa kupisa uye kuchengetedza kupisa simba, kunatsiridza mashandisiro ekupisa. tsime, kupisa kwekudzivirira mhedzisiro ndiyo yechinyakare zvinhu 3 ~ 5 nguva, uye hupenyu hurefu.
Mumunda wemuchadenga
Airgel thermal insulation material inogona kushandiswa sechinhu chinopisa chekudzivirira chemukati wendege, chinogona kusimudzira kupisa kwekupisa, kuderedza tembiricha yekabhini, kunyatso dzikisa huwandu hwemafuta ekudzivirira, kuwedzera nzvimbo yekushandiswa mukabhini, uye nekuvandudza zvakasiyana-siyana. nzvimbo dzekushanda.Airgel thermal insulation material inogona kuwana zvirinani kupisa kwemafuta ekudzivirira nekureruka mashoma uye vhoriyamu diki, iyo ine mabhenefiti makuru mumunda wendege uye aerospace application.
Mumunda wekuvaka
Nekuenderera mberi kwekuvandudzwa kwezvinodiwa zvenyika zvekuchengetedza simba uye kuderedzwa kwekubuda, uye kutsvaga kwevanhu kwehupenyu hwehupenyu, kuvharwa kwekuvaka kwave zvishoma nezvishoma kuve musoro wakakosha mumunda wekuvaka.Kune chivako, zvinenge zvikamu zvose, zvinobatanidzwa mukudiwa kwekupisa kwekushisa, kunyanya mumadziro emadziro emadziro, denga rekuvhara pasi.Silica airgel inogona kumira tembiricha yakanyanya, kazhinji pa800 ℃, chimiro chayo, kuita kwayo hakuna shanduko iri pachena, yakachengeteka, inochengetedza simba, kuchengetedzwa kwezvakatipoteredza kweiyo super insulation zvinhu.
Mumunda wekutakura
Iko kupisa kwekudzivirira kwekuita kwedenga remotokari ndechimwe chezvinhu zvikuru zvinokanganisa kutamisa kupisa kwemuviri wemotokari.Izvo zvakakosha zvikuru pakuongorora mashandisirwo emagetsi ekufambisa kwemotokari, kuona mutoro wayo wemhepo, kudzivirira kuitika kwemamiriro ekushanda akaipa, uye kuchengetedza nharaunda yekudziya inopisa mukati memotokari.Mumunda wemagetsi emagetsi matsva, moto wemotokari yemagetsi uye njodzi dzinoputika dzinokonzerwa ne lithium ion bhatiri "thermal runaway" zvakataurwa kakawanda.Maitiro ekunyatso simbisa kupisa kwekushisa uye kuchengetedzeka kwe lithium bhatiri rave "bakatwa reDamocles" rakarembera pamusoro pemusoro wemafekitori emotokari uye emagetsi mabhatiri mabhizinesi.Nanoporous airgel composite insulation materials yakaiswa kune zvitima zvinomhanya-mhanya, ndege yemumba yeC919 yevatyairi, uye mota nyowani dzine simba, kunyanya yakatarisana nekupisa kwekupisa kwemotokari dzekutakura uye kuchengetedzwa kwemabhatiri e lithium mumotokari nyowani dzesimba.
Tsanangudzo
Zvinoenderana nekusarudzwa kweakasiyana substrate, airgel mat inogona kusarudza akasiyana composite akateedzana zvichienderana neakasiyana zvinodiwa nevatengi uye mamiriro.Parizvino, pane kunyanya mana akatevedzana egirazi faibha inoumba aerogels (HHA-GZ), preoxygenated waya faibha inoumba aerogels (HHA-YYZ), yakakwirira silicon okisijeni faibha composite aerogels (HHA-HGZ) uye ceramic fiber composite aerogels (HHA-TCZ )Iyo yakatarwa parameters ndeiyi inotevera:
Zvinoenderana neaya ekudzivirira kupisa masisitimu, machira ekupisa kupisa evhavha anogona kupatsanurwa mumhando nhatu: chipingamupinyi rudzi, kuratidzira mhando uye radiation mhando.isu suzhou supxtech kambani inogona kupa iyo Airgel coating tekinoroji uye muchina, inogona kushandiswa kune colth, pepa repurasitiki uye kunzwa.Inoshandiswa zvakanyanya munzvimbo inodziya.
Barrier heat insulation coating imhando yekusevha kutonhora coating iyo inoziva kupisa kwekushisa kuburikidza ne impedance mhedzisiro yekupisa kupisa.Iyo yekupisa yekupisa nzira iri nyore, uye iyo inoumbwa ine yakaderera thermal conductivity kana mhepo ine yakaderera kwazvo yekupisa conductivity inounzwa mufirimu kuti iwane yakanaka yekupisa kupisa.Iyo inowanzo ine hunhu hwehudiki huzhinji density, yakaderera thermal conductivity uye diki dielectric constant.
Reflective heat insulation coating ndeyekuparadzanisa simba rezuva muchimiro chekuratidzira.Zvinowanzoshandiswa zvinoratidzira zvinosanganisira ceramic powder, aluminium poda, titanium dioxide uye ATO (antimony doped tin dioxide) poda.
Yakajairika chipingamupinyi chinopisa chinopisa chivhariso chekuisa mumiriri zvinoenderana nechimiro chemakemikari, kunyanya inosanganisira polyvinyl chloride (PVC), polyacrylate (PA), polyurethane (PU), silicone, emulsion yerabha uye polytetrafluoroethylene, pakati peiyo PA nePU inonyanya kushandiswa;Zvinoenderana nekushandiswa kwepakati, inogona kukamurwa kuita solvent uye mvura yakaparadzirwa mhando 2.
SiO2 airgel is an amorphous nanoporous material ine controllable structure uye inoenderera ine matatu-dimensional network chimiro.Uye kuwanda kwayo kunogadziriswa pakati pe3 ~ 500mg/cm3, ndiyo yakaderera pasi rose density yechinhu chakasimba, porosity inogona kusvika 80% ~ 99.8%, pore size pakati pe1 ~ 100nm, nzvimbo chaiyo inogona kusvika ku1000m2/g.Nekuda kweiyo yakasarudzika nanoporous dhizaini, yayo yekupisa conductivity yakadzikira zvakanyanya, yakaderera se0.017W/ (m • K) pakamuri tembiricha uye kudzvanywa, zvichiita kuti ive yakaderera inozivikanwa yakasimba zvinhu ine thermal conductivity.Nekuti iyo unit unit yeairgel skeleton idiki pane wavelength yechiedza chinooneka, ine zvakare yakanaka kutapurirana mwenje kuita.Panguva imwecheteyo, iyo inorganic material, ine-isina-kupisa kana murazvo wemoto, mumunda wekupisa kwekushisa kune huwandu hwakawanda hwemashandisirwo.
