1. Taw Qhia: Thoob plaws ntawm Airgel thiab kev sib cav sib ceg ntawm kev nyab xeeb tawv nqaij
Nyob rau hauv xyoo tsis ntev los no, Airgel tau ua lub luag haujlwm tseem ceeb hauv kev tsim kho, kev tsim kho thiab lwm cov teb nrog rwb thaiv tsev nakal, cua sov thiab kev hnyav. Nrog kev txhim kho thev naus laus zis, Airgel tau koom nrog cov khoom lag luam thermal, xws li, nws muaj kev nyab xeeb hauv kev sib cuag nrog daim tawv nqaij tau ua rau muaj kev sib raug zoo. Ntawm ib sab tes, cov tuam txhab ua lag luamairgel khoomuas tuaj yeem coj kev yooj yim thiab sov siab; Ntawm qhov tod tes, cov neeg siv cov neeg siv tau txhawj xeeb tias nws yuav ua rau cov tawv nqaij ua xua, voos thiab lwm yam teeb meem.
2. Muaj pes tsawg leeg thiab cov yam ntxwv ntawm Airgel: Lub hauv paus ntawm kev ntsuas kev nyab xeeb
Aerogels tuaj yeem faib ua silicon airgel, carbon ò, hlau oxide oxigel, thiab lwm yam raws li lawv muaj pes tsawg leeg. Cov muaj pes tsawg leeg thiab cov yam ntxwv ntawm cov sib txawv cuam tshuam rau lawv txoj kev nyab xeeb rau lawv txoj kev sib cuag nrog daim tawv nqaij, raws li qhia hauv qab no:
| Airgel Hom | Cov khoom xyaw tseem ceeb | Porosity ntau | Cov yam ntxwv ntom ntom | Tshuaj Muaj Peev Xwm |
| Silicon Airgel | Silicon Dioxide (\ (sio _2 \)) | 80% - 99.8% | Tsawg heev, ze rau lossis me ntsis siab dua cua | Tshuaj lom neeg muaj qhov ruaj khov thiab tsis hnov mob nrog cov acids thiab hauv paus |
| Carbon Airgel | Cov Khoom Siv Hluav Taws Xob Cov Khoom Siv | Siab porosity (txawv los ntawm subtype) | Tsawg, nyob ntawm cov pa roj carbon chaw thiab cov qauv | Kev ruaj khov zoo, tab sis qee cov ntaub ntawv carbon yuav cuam tshuam cov tshuaj carbon muaj cov muaj zog oxidants |
| Hlau Oxide Airgel | Hlau oxides (xws li \ (tio _2 \), \ (al {1} {2}}) | Siab porosity | Sib txawv vim hlau oxide thiab npaj txoj kev | Tshuaj lom neeg zoo, tab sis qee cov hlau oxides yuav yaj nyob rau hauv qee cov kua qaub-hauv paus |
Txawm hais tias airgel nws tus kheej yog chemically ruaj khov, organic cov kuab tshuaj xws li Methanol thiab ethanol thiab hloov cov kev ntxiv nyob rau hauv cov txheej txheem npaj. Yog tias cov tshuaj no nyob, lawv yuav ua rau daim tawv; Qee cov ntaub ntawv siv hauv kev hloov kho saum npoo kuj muaj kev txaus ntshai. Tsis tas li, cov qauv tsis txaus ntseeg ntawm airgel yog nquag los ua cov khoom zoo, uas ua rau muaj kev pheej hmoo ntawm kev sib cuag nrog daim tawv nqaij.
3. Kev nyab xeeb nyob rau hauv ib txwm siv: tib neeg kev soj ntsuam thiab sim cov ntaub ntawv
Nyob rau hauv ib txwm muaj xwm txheej, airgel muaj kev nyab xeeb rau nkag mus ncaj qha rau daim tawv nqaij. Nws lub ntsiab tivthaiv, silicon dioxide, yog cov ensically inert thiab tsis nquag rau kev ua xua. Thaum Airgel tau ua rau cov khoom lag luam xws li khaub ncaws, feem ntau nws yog qhov txuas nrog lwm cov ntaub kom txo cov chaw sib cuag ncaj qha.
Qhov no yog paub tseeb los ntawm ntau tus neeg hnav cov ntaub ntawv ntsuas. Ib hom kev paub sab nraum zoov hom ua rau peb-lub hlis ntsuas cua sov cov khaub ncaws rau 1, 000 neeg tuaj yeem pab dawb. Cov txiaj ntsig tau pom tias tsuas yog 8 tus neeg ua haujlwm pub dawb (account}. 8%) qhia txog cov tawv nqaij uas rhiab thiab hnav khaub ncaws, tsis ncaj qha los ntawm Airgel. Lwm cov qauv kev ntsuas pom tau pom tias cov txheej txheem ntxig ua rau nws ua pa ntawm cov tawv nqaij txias
4. Cov xwm txheej muaj kev pheej hmoo: Kev puas tsuaj, kub thiab cov khoom xyaw tseem ceeb
Txawm hais tias muaj kev nyab xeeb rau kev siv Aerogel, Aerogels ua rau cov kev pheej hmoo ntawm daim tawv nqaij tshwj xeeb. Thaum cov khoom puas lawm, cov khoom zoo tso tawm los ntawm lub airgel yuav nkag mus rau cov hws thiab ua kom khaus, liab thiab o ntawm daim tawv nqaij. Kev ntsuam xyuas ntawm cov neeg muaj cov tawv nqaij rhiab uas tau ntsib cov tsos mob txawv ntawm cov nqaij tawv nqaij tom qab sib cuag nrog Airgel hais.
Cov seem ntawm cov kuab tshuaj organic thiab hloov kho thaum lub sijhawm npaj tau npaj kuj yog pose kev pheej hmoo. Cov kev tshawb fawb pom tau tias yog tias cov khoom methanol nyob rau hauv cov khoom tshaj li 15% ntawm 15% ntawm kev ntsuas tshuaj yuav tsim cov tsos mob tom qab 72 teev ntawm kev sib cuag tom qab. Tsis tas li ntawd, qhov chaw kub ib puag ncig tuaj yeem cuam tshuam rau cov tshuaj ruaj khov ntawm aerogels. Tom qab qee lub hom phiaj ntawm Airgel Cov Kev Tiv Thaiv Kev Ntaus Pob Ncaws Pob tau siv rau 45 degree, nws tau pom tias cov teeb meem phom sij tau tso tawm, ua rau pob khaus tawv nqaij hauv 12% ntawm cov neeg siv.
5. Kev Lag Luam Cov Qauv Kev Lag Luam thiab Kev Tiv Thaiv Kev Tiv Thaiv: Cov Qauv los xyuas kom muaj kev nyab xeeb
Txhawm rau kom muaj kev nyab xeeb ntawmTsho tiv no nrog rwb thaiv tsev airgel, kev lag luam tau teeb tsa cov qauv nruj. Hauv kuv lub teb chaws, nws tau hais tias cov residual cov ntsiab lus hauv {{{}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} EU ncav cuag cov cai tseem yuav muab cov ncauj lus kom ntxaws rau cov khoom siv thiab kev nyab xeeb ntawm cov qauv kev nyab xeeb rau kev tiv thaiv tawv nqaij.
Kev lag luam nquag nquag siv kev tiv thaiv kev tiv thaiv. Ua kom tau cov txheej txheem ntau lawm, xws li siv cov thev naus laus zis ua kom qhuav, tuaj yeem txo cov residual organic kuab cov ntsiab lus kom tsawg dua 0. 05%; Ntxiv dag zog rau cov txheej txheem sib xyaw ua ke thaum cov khoom tsim qauv, xws li cov tshuab hluav taws xob nruj nrog polyester fiber, yog li cov khoom lag luam tiv thaiv kev puas tsuaj yog nce 40%. Nyob rau tib lub sijhawm, cov phau ntawv khoom yuav ua kom meej meej khij lub tuam txhab kev ua kom muaj kev nyab xeeb kom ntseeg tau tias cov tswv yim muaj kev nyab xeeb yog ua raws sijhawm.
6. Kev thov cov xwm txheej thiab cov zeem muag: kev nyab xeeb thiab kev txhim kho ob sab tes ua ke
Ntawm tam sim no, Aerogels tau siv dav hauv cov khoom sib chwv rau hauv cov khoom lag luam tawv nqaij thiab muaj cov kev cia siab. Hauv daim teb ntawm cov me nyuam cov khoom, ib hom phiaj ntawm Airgel tus menyuam pw tsaug zog tau txais kev ntsuas cov tawv nqaij nruj me me, thiab cov tshuaj tua hluav taws xob nruj thiab ua kom cov niam txiv muaj kev nyiam kev nyab xeeb; Hauv cov teb kho mob, cov ntaub qhwv cov cua sov tuaj yeem ua kom muaj qhov txhab ruaj khov thiab txo qhov tshwm sim ntawm daim tawv nqaij teeb meem los ntawm 18%.
Nyob rau hauv lub neej yav tom ntej, nrog thev naus laus zis kev nce qib, airgel cov khoom yuav muaj kev nyab xeeb dua. Cov kws tshawb nrhiav tab tom txhim kho cov khoom tsis muaj tshuaj ntxiv thiab kev npaj ua kom txo cov tawv nqaij tiv thaiv cov tawv nqaij tiv thaiv ntawm 50%. Tib lub sijhawm, cov huab cua yuav tsum nthuav mus rau hauv cov ntaub hnav ntse, kev zoo nkauj thiab tu tawv nqaij, thiab lwm thaj chaw, nqa khoom muaj kev nyab xeeb thiab xis nyob rau cov neeg siv khoom.
7. Xaus: Muaj kuab lomition txhawb kev nyab xeeb kev siv Airgel
Nyob rau hauv dav dav, Airgel kuj muaj kev nyab xeeb rau daim tawv nqaij hauv ib txwm siv, tab sis muaj kev pheej hmoo hauv cov xwm txheej tshwj xeeb. Kev phom sij tuaj yeem txo qis los ntawm kev tshawb fawb, txhim kho cov qauv thiab kev tiv thaiv zoo. Cov neeg tau txais kev pab yuav tsum saib cov khoom siv airgel rationally thiab xyuam xim rau cov lus qhia rau kev siv; Cov tuam txhab yuav tsum tau txuas ntxiv kom ua kom muaj kev nyab xeeb kom ntseeg tau tias cov khoom muaj kev nyab xeeb. Kev sib koom tes ntawm txhua tus neeg yuav txhawb nqa kev nyab xeeb thiab thoob plaws ntawm Airgel hauv thaj teb ntawm daim tawv nqaij hu.
