Foamed iav

foamed iav
Kuj hu ua porous iav los yog iav ua npuas ncauj. Nws yog ib qho iav insulating tsim los ntawm cov pores sib xws nrog lub porosity ntawm ntau dua 90%. Vim nws cov qauv pore muaj lub cev muaj zog ntawm borosilicate, nws yog siv los ua cov khoom siv thermal rwb thaiv tsev nrog cov yam ntxwv xws li tsis muaj permeability, tsis combustion, tsis deformation, tsis deterioration, thiab tsis kis ntawm cov zaub mov. Yog li ntawd, nws tsis yog tsuas yog siv los ua cov khoom siv hluav taws xob tsis zoo rau cov khoom siv hauv tsev thiab sab nraum zoov, tab sis kuj rau cov khoom noj khoom haus khov fermentation thiab brewing, kua qib ntsuas floats, thiab lwm yam.
ntau lawm txoj cai
Ua npuas ncauj iav yog thawj zaug tsim los ntawm Corning, Pittsburgh, Tebchaws Asmeskas. Nws yog ib qho inorganic uas tsis yog- iav cov khoom siv hlau ua los ntawm cullet, foaming agent, hloov kho additive thiab foaming accelerator, uas yog finely crushed thiab sib tov sib xyaw, ces melted, foamed thiab annealed ntawm kub. Nws yog tsim los ntawm ib tug loj tus naj npawb ntawm cov qauv ua npuas ncauj nrog ib txoj kab uas hla ntawm 1-2 millimeters. Ntawm lawv, lub suab absorbing ua npuas ncauj iav muaj ntau tshaj 50% ntawm cov xov tooj ntawm tes qhib npuas, thiab cov thermal rwb thaiv tsev ua npuas ncauj iav muaj ntau tshaj 75% ntawm cov xov tooj ntawm tes kaw npuas, uas tuaj yeem hloov kho los ntawm kev hloov cov khoom tsim tawm raws li kev siv.
Vim nws cov dej noo- pov thawj, fireproof, thiab los tiv thaiv- corrosion kuj, nrog rau lub sij hawm ntev - kev ua tau zoo ntawm iav cov ntaub ntawv, cov khoom tshiab no nyiam heev los ntawm cov neeg siv nyob rau hauv ib puag ncig hnyav xws li rwb thaiv tsev, sib sib zog nqus txias, hauv av, sab nraum zoov, flammable, humid, thiab tshuaj yaig. Dav siv nyob rau hauv cov phab ntsa rwb thaiv tsev, roj av, tshuaj, tshuab chav tsev suab nrov txo, kev loj suab-absorbing phab ntsa, fais fab, tub rog khoom, thiab lwm yam., nws yog hu ua ib tug ntsuab thiab environmentally phooj ywg rwb thaiv tsev khoom los ntawm cov neeg siv.
Raws li ntau yam khoom ntawm cov iav ua npuas ncauj, nws tuaj yeem siv los ua cov khoom siv thermal rwb thaiv tsev hauv ntau lub tuam tsev ntawm kev tsim kho engineering, nrog rau hauv kev tsim nkoj, tshuaj lom neeg kev lag luam, tsis tshua muaj kub thiab kub siab. Dawb thiab xim iav kuj tseem siv los ua suab- nqus thiab cov khoom siv zoo nkauj. Cov khoom pov tseg hauv kev tsim khoom - ua npuas ncauj iav hmoov thiab cov khoom seem tuaj yeem siv los ua cov khoom siv rau cov pob zeb zoo nkauj thiab lwm yam. Raws li kev siv sib txawv, cov khoom siv iav ua npuas dej ua los ntawm cov txheej txheem sib xws tuaj yeem muab faib ua plaub pawg, xws li, thermal rwb thaiv tsev ua npuas ncauj iav, suab- nqus cov iav ua npuas ncauj, cov iav ua npuas ncauj zoo nkauj thiab cov iav ua npuas ncauj.
kev ntsuas kev ua haujlwm
Lub ntim hnyav ntawm cov iav rwb thaiv tsev yog lub teeb, txog 160kg / m; 2. Lub thermal conductivity yog me me, qis dua 0.058 w / m * k, thiab thermal conductivity yog ruaj khov; 3. Tsis breathable; 4. Kev nqus dej tsawg, nyob ib ncig ntawm 0.2%; 5 tsis hlawv; 6. Tsis muaj pwm lossis corrosion; 7. Lub zog siab, compressive zog Ntau dua lossis sib npaug ntawm 0.7Mpa, flexural zog Ntau dua lossis sib npaug ntawm 0.5Mpa; 8. tuaj yeem tiv taus acid corrosion (tsis suav nrog hydrogen fluoride); 9 tsis yog{13}} tshuaj lom thiab tsis muaj CFC (chlorofluorocarbon carbon) lossis HCFCs (hydrochlorofluorocarbon); 10 Lub cev thiab tshuaj lom neeg ruaj khov, ruaj khov, yooj yim txiav 3 ua npuas ncauj iav rwb thaiv tsev sab nrauv phab ntsa rwb thaiv tsev system tsim cov txheej txheem txheej txheem ntawm cov iav iav sab nrauv phab ntsa rwb thaiv tsev los ntawm sab hauv mus rau sab nrauv yuav tsum yog: kev sib txuas txheej, foam iav rwb thaiv tsev txheej, ntsej muag txheej, txheej txheej, uas cov txheej txheej plastering tsuas yog siv rau qib phab ntsa txheej txheej phab ntsa, ruaj khov thiab tiv thaiv cov iav txheej txheej ntawm phab ntsa. lub firmness ntawm lub zog rwb thaiv tsev system thiab tiv thaiv dej seepage. Lub thickness ntawm foam iav rwb thaiv tsev txheej yuav tsum tau xam thiab txiav txim raws li cov khoom thiab thickness ntawm lub sab nrauv phab ntsa puag thiab lub zog txuag yuav tsum tau ntawm lub sab nrauv phab ntsa. Cov iav ua npuas ncauj sab nrauv phab ntsa rwb thaiv tsev tuaj yeem ua ke nrog cov txheej txheem phab ntsa sab nrauv ntawm lwm cov ntaub ntawv organic raws li cov txheej txheem rwb thaiv tsev los tiv thaiv phab ntsa sab nraud los ntawm kev kub hnyiab.
