Airgel Spunlace Non-woven Npuag
Khoom Taw Qhia:
Airgel spunlace non-woven npuag yog ib hom tshiab ntawm cov khoom siv ua haujlwm siab ua los ntawm kev sib xyaw ntawm cov khoom siv airgel / fibers nrog cov pa fibers (xws li polyester thiab viscose) los ntawm cov txheej txheem spunlace. Nws cov txiaj ntsig tseem ceeb yog "qhov kawg thermal rwb thaiv tsev + lub teeb yuag".
Nws khaws cov cuab yeej thermal rwb thaiv tsev super ntawm aerogel, nrog rau qhov tsis tshua muaj thermal conductivity, uas tuaj yeem tiv thaiv kom tsis txhob muaj cua sov. Nyob rau tib lub sijhawm, cia siab rau cov txheej txheem spunlace, nws yog mos thiab hloov tau yooj yim hauv kev ntxhib los mos, tshem tawm cov brittleness ntawm cov tsoos aerogels. Nws kuj muaj lub teeb yuag, qee qhov ua pa thiab tsis yooj yim rau deformation.
Daim ntawv thov tsom mus rau cov xwm txheej ntawm cov hluav taws xob hluav taws xob zoo: xws li cov hauv ob sab hauv ntawm cov khaub ncaws txias thiab cov hnab pw tsaug zog, cov txheej txheem rwb thaiv tsev ntawm cov phab ntsa thiab cov kav dej, cov cua sov dissipation tsis siv cov khoom siv hluav taws xob (xws li cov roj teeb thiab cov chips), thiab cov khoom siv hluav taws xob sib xyaw ua ke hauv lub tshav dav hlau, ntsuas qhov ntsuas kub ntawm kev ua haujlwm thiab kev siv.
YDL Nonwovens tshwj xeeb hauv kev tsim cov airgel non-woven npuag thiab txhawb kev tsim kho raws li cov neeg siv khoom xav tau.
Cov hauv qab no yog kev qhia txog cov yam ntxwv thiab daim ntawv thov teb ntawm airgel spunlace nonwoven fabric:
I. Cov yam ntxwv tseem ceeb
Thaum tshav kub kub rwb thaiv tsev thiab lub teeb yuag: Cov ntsiab lus tseem ceeb, aerogel, yog ib qho ntawm cov khoom siv nrog cov thermal conductivity qis tshaj. Lub thermal conductivity ntawm cov khoom tiav yog feem ntau tsawg dua 0.03W / (m · K), thiab nws cov rwb thaiv tsev kub zoo tshaj li ntawm cov tsoos tsis-woven fabrics. Ntxiv mus, lub airgel nws tus kheej muaj qhov tsawg tsis tshua muaj zog (tsuas yog 3-50kg / m³), thiab ua ke nrog cov txheej txheem flungry, cov khoom siv ua ib qho kev sib xyaw ua ke thiab tsis muaj kev nkag siab hnyav.
Ua txhaum los ntawm cov kev txwv ntawm cov tsoos aerogels: Cov tsoos aerogels yog nkig thiab ua rau tawg. Txawm li cas los xij, cov txheej txheem spunlace ruaj khov kho cov airgel particles / fibers los ntawm fiber ntau interweaving, endowing cov khoom nrog softness thiab toughness, cia nws yuav tsum tau khoov, folded, thiab yooj yim txiav thiab ua tiav. Nyob rau tib lub sijhawm, nws khaws qee qhov kev ua pa ntawm kev ua pa, tsis txhob hnov qab txog qhov mob.
Cov huab cua ruaj khov thiab kev nyab xeeb: Nws muaj ntau yam ntawm qhov kub thiab txias tsis kam thiab tuaj yeem ua haujlwm ruaj khov hauv ib puag ncig ntawm -196 ℃ to 200 ℃. Feem ntau hom tsis yog-flammable, tsis tso tshuaj lom, thiab tiv taus kev laus thiab corrosion. Lawv cov hluav taws kub rwb thaiv tsev ua haujlwm tsis yooj yim poob rau hauv qhov chaw ntub dej, acidic lossis alkaline ib puag ncig, thiab lawv muaj kev nyab xeeb thiab siv tau ntev.
II. Main Application Fields
Hauv kev tiv thaiv kev tiv thaiv thermal: Nws yog siv los ua cov ntaub hauv cov khaub ncaws txias-pov thawj, cov ris tsho nce toj, cov kev tshawb fawb txog kev tshawb fawb txog kev sib tw, nrog rau cov khoom ntim rau sab nraum zoov pw tsaug zog hnab thiab hnab looj tes, ua kom muaj kev tiv thaiv thermal los ntawm kev sib tw thiab txo cov load. Nws kuj tseem tuaj yeem siv los ua cov rwb thaiv tsev kub tiv thaiv txheej rau cov neeg tua hluav taws thiab cov neeg ua haujlwm hlau los tiv thaiv kev raug mob kub.
Lub tsev thiab kev lag luam rwb thaiv tsev: Raws li cov khoom siv rwb thaiv tsev rau lub tsev sab nrauv phab ntsa thiab lub ru tsev, los yog txheej rwb thaiv tsev rau cov kav dej thiab cov tso tsheb hlau luam, nws txo qis kev siv hluav taws xob. Hauv kev lag luam, nws yog siv los ua cov ntaub ntawv insulating rau cov khoom siv xws li cov tshuab hluav taws xob thiab cov boilers, nrog rau cov khoom siv hluav taws xob tsis zoo rau cov khoom siv hluav taws xob (xws li lithium roj teeb thiab chips), los tiv thaiv cov cua sov hauv zos.
Aerospace thiab kev thauj mus los: Ua tau raws li qhov yuav tsum tau ua ntawm lub teeb yuag ntawm cov khoom siv hauv aerospace, xws li cov txheej rwb thaiv tsev rau lub dav hlau cabins thiab kev tiv thaiv rau cov khoom siv satellite; Hauv kev thauj mus los, nws tuaj yeem siv los ua cov khoom siv insulating rau cov khoom siv roj teeb ntawm cov tsheb tshiab lub zog lossis ua cov txheej txheem hluav taws kub thiab cov cua sov-insulating rau sab hauv ntawm cov tsheb ciav hlau ceev thiab dav hlau, suav nrog kev nyab xeeb thiab qhov hnyav.
