1. Zoo txhua yam kev puas tsuaj kuj:muaj zoo tensile, compressive thiab dabtsi yog khoov tsis kam, nyob rau hauv lub installation thiab siv cov txheej txheem, txawm yog raug rau ib tug tej degree ntawm sab nraud quab yuam, nws tsis yooj yim rau tawg, tawg, thiab lwm yam., kom ntseeg tau tias nws ib txwm siv nyob rau hauv complex tej yam kev mob.
2. Lub teeb yuag:Airgel nws tus kheej yog cov khoom siv tsawg tsawg, airgel phaj tau txais cov yam ntxwv no, kuj lub teeb, yooj yim rau kev tswj, kev teeb tsa thiab kev tsim kho, tuaj yeem txo kev siv zog thiab kev tsim kho nyuaj, tab sis kuj txo cov kev xav tau ntawm cov qauv kev txhawb nqa, hauv kev nruj. Cov kev txwv ntawm qhov hnyav, xws li aerospace, muaj txiaj ntsig zoo.
3. Kev tiv thaiv ib puag ncig thiab txuag hluav taws xob:Airgel phaj yog non-toxic, tasteless, non-polluting, harmless rau tib neeg lub cev thiab ib puag ncig. Nws cov txheej txheem ntau lawm feem ntau yog siv cov khoom siv raw khoom thiab cov txheej txheem, tsis muaj cov khoom tsim kev puas tsuaj, raws li kev txhim kho lub tswv yim ntawm kev tiv thaiv ib puag ncig qis. Tsis tas li ntawd, nws cov thermal rwb thaiv tsev ua tau zoo tuaj yeem txo qis kev siv hluav taws xob hauv tsev thiab kev siv hluav taws xob ntawm cov khoom siv, txo cov hluav taws xob pov tseg thiab carbon dioxide emissions.
Cov txheej txheem ntau lawm
1.Sol-gel txheej txheem
Raw khoom xaiv thiab sib tov:Xaiv cov khoom siv silicon uas tsim nyog, xws li methyl orthosilicate, ethyl orthosilicate, sodium silicate, thiab lwm yam, thiab sib tov nrog cov kuab tshuaj thiab cov catalysts. Siv ethyl orthosilicate ua piv txwv, feem ntau tov nrog ethanol thiab lwm cov kuab tshuaj, thiab ntxiv cov kua qaub los yog lub hauv paus tsim nyog, xws li hydrochloric acid, ammonia thiab lwm yam.
Hydrolysis thiab polycondensation cov tshuaj tiv thaiv:Nyob rau hauv tej yam kub thiab nplawm tej yam kev mob, silicon qhov chaw yog hydrolyzed los tsim silanol. Lub silanol yog ntxiv cov tshuaj tiv thaiv polycondensation, tsim cov qauv peb-dimensional network ntawm cov gel ntub dej. Thaum lub sij hawm cov txheej txheem tshuaj tiv thaiv, tsis xws li cov tshuaj tiv thaiv kub, lub sij hawm thiab pH tus nqi yuav tsum tau tswj kom tau cov gel nrog cov khoom uas xav tau.
2.Kev tsim thiab kev laus
Txhaj tshuaj molding:Cov gel ntub dej yog nchuav rau hauv cov pwm tsim ua ntej, kom nws tau tsim rau hauv cov phaj xav tau hauv pwm. Cov khoom thiab cov duab ntawm cov pwm yuav cuam tshuam qhov loj thiab qhov zoo ntawm cov phaj airgel.
Kev laus kev kho mob:Cov gel tom qab txhaj tshuaj yog muaj hnub nyoog nyob rau hauv tej yam kub thiab av noo tej yam kev mob, thiaj li hais tias cov qauv ntawm cov gel yog ruaj khov thiab zoo meej, feem ntau cov laus lub sij hawm txawv ntawm ob peb teev mus rau ob peb hnub.
3. Kev kho kom qhuav
Supercritical drying:Qhov no yog feem ntau siv txoj kev ziab khaub ncaws, cov laus ntub dej gel yog muab tso rau hauv ib qho autoclave, cov kuab tshuaj yog rhuab thiab pressurized kom ncav cuag lub xeev supercritical, thiab tom qab ntawd lub siab maj mam txo, kom cov kuab tshuaj raug tshem tawm hauv lub xeev supercritical, yog li kom tsis txhob muaj cov qauv gel tsoo vim muaj zog capillary thaum lub sijhawm ziab. Supercritical drying yuav tsum nruj tswj qhov kub, siab thiab lub sij hawm ziab.
Atmospheric qhuav:Qee zaum, huab cua kom qhuav kuj tuaj yeem siv tau, tab sis kev kho tshwj xeeb ntawm cov gel yog xav tau, xws li ntxiv cov tshuaj tiv thaiv ziab kom qhuav, kom txo tau qhov shrinkage thiab tawg ntawm cov gel thaum lub sij hawm ziab.
4.Postprocessing
Txiav thiab ua:Raws li daim ntawv thov tiag tiag xav tau, lub phaj airgel qhuav yog txiav rau hauv qhov loj thiab zoo, thiab kev kho saum npoo yog nqa tawm, xws li kev sib tsoo, polishing, thiab lwm yam, txhawm rau txhim kho qhov smoothness thiab tiav.
Composite thiab reinforcement:Txhawm rau txhim kho cov khoom siv thiab kev ua tau zoo ntawm cov phaj airgel, cov phaj airgel feem ntau yog sib xyaw nrog lwm cov ntaub ntawv, xws li pasting cov khoom siv ntxiv xws li iav fiber ntau daim ntaub thiab cov ntaub ntawv carbon fiber nyob rau saum npoo ntawm lub phaj airgel, los yog sib tov cov airgel. thiab fiber ntau los ua cov phaj sib xyaw.
