Porous spray-coated polyurethane foams (SPF) yog dav siv rau thermal rwb thaiv tsev, suab rwb thaiv tsev thiab lub teeb yuag cov ntaub ntawv. Kev tsim khoom thiab kev ua tau zoo ntawm SPF tuaj yeem ua kom zoo dua los ntawm kev ntxiv cov catalysts xws liMXC-37 (2-[2- (dimethylamino) ethoxy] ethanol, DMAEE). Cov catalysts zoo li no muaj txiaj ntsig zoo hauv kev daws cov teeb meem xws li amine tsw thiab hauv kev sib npaug reactivity hauv formulations nrog cov ntsiab lus dej siab.
1. Lub luag haujlwm ntawm MXC-37 hauv SPFs
MXC-37 tuaj yeem siv los ua lub ntsiab lossis co-catalyst los txhim kho cov txheej txheem foaming thiab kho:
Txo amine saj:Ib qho txiaj ntsig tseem ceeb tshaj plaws ntawm MXC-37 yog nws lub peev xwm los txo qis cov amine saj hauv cov khoom tiav. Lub active hydrogen nyob rau hauv nws cov qauv yog incorporated rau hauv lub polymer matrix, txo cov residual volatile amines.
High dej compatibility:MXC-37 nthuav tawm cov kev ua haujlwm siab catalytic hauv cov qauv dej, ua rau nws xaiv dav rau cov tshuab ua npuas ncauj uas siv dej ua tus neeg sawv cev fowing.
Kev siv yooj yim:nws tuaj yeem siv los ua lub ntsiab catalyst ib leeg, lossis nrog BDMAEE (bis [2- (dimethylamino) ethyl] ether) thiab lwm yam tertiary amines ua cocatalysts los txo qhov kev thov rau BDMAEE thiab txhim kho tus nqi efficiency.
2. Qhov zoo ntawm SPF ntau lawm
MXC-37 tuaj yeem siv los ua lub ntsiab lossis co-catalyst los txhim kho cov txheej txheem foaming thiab kho:
Txo amine saj:Ib qho ntawm qhov tseem ceeb tshaj plaws ntawmMXC -37yog nws lub peev xwm los txo qhov raug amine saj hauv cov khoom tiav. Lub active hydrogen nyob rau hauv nws cov qauv yog incorporated rau hauv lub polymer matrix, txo cov residual volatile amines.
High dej compatibility:MXC-37 nthuav tawm cov kev ua haujlwm siab catalytic hauv cov qauv dej, ua rau nws xaiv dav rau cov tshuab ua npuas ncauj uas siv dej ua tus neeg sawv cev fowing.
Kev siv yooj yim:nws tuaj yeem siv los ua lub ntsiab catalyst ib leeg, lossis nrog BDMAEE (bis [2- (dimethylamino) ethyl] ether) thiab lwm yam tertiary amines ua cocatalysts los txo qhov kev thov rau BDMAEE thiab txhim kho tus nqi efficiency.
3. Cov ntawv thov tseem ceeb ntawm Porous SPFs
Porous SPFs catalyzed los ntawm MXC-37 pom cov ntawv thov hauv ntau qhov chaw:
Thermal rwb thaiv tsev:Siv nyob rau hauv lub tsev phab ntsa, ru tsev, thiab industrial pipelines los txhim kho lub zog efficiency.
Soundproofing:Cov qauv qhib-cell ntawm ntxeem tau SPFs absorbs suab nthwv dej, ua rau lawv haum rau acoustic rwb thaiv tsev nyob rau hauv cov chaw nyob thiab ua lag luam.
Lightweight Fillers:Porous SPFs yog siv nyob rau hauv cov khoom siv hnyav, txo qhov hnyav tag nrho yam tsis muaj kev cuam tshuam lub zog.
Cov khoom ntim:Lawv cov khoom poob siab-absorbing ua rau lawv zoo tagnrho rau kev tiv thaiv ntim.
4. MXC-37 as a Cocatalyst
Thaum siv nrog BDMAEE lossis lwm yam amine catalysts, MXC-37 muab:
Txhim kho Reactivity Control:Ntsuas cov foaming thiab gel cov tshuaj tiv thaiv, kom ntseeg tau tias ua npuas ncauj zoo.
Txo Catalyst Dosage:Txo qhov kev xav tau rau ntau dua ntawm BDMAEE, ua rau cov nqi txuag thiab txo qis emissions.
Customizable Performance:Tso cai rau kev kho kom zoo ntawm cov catalyst system rau kev ua haujlwm tshwj xeeb thiab cov kev xav tau ua haujlwm.
Vim li cas thiaj xaiv MXC -37 rau SPFs?
1. Txo cov ntxhiab tsw: Txo cov ntxhiab tsw amine hauv cov khoom kawg, txhim kho cov neeg siv kev paub.
2. Versatility: Haum rau ob qho tib si qhib-cell thiab kaw-cell ua npuas ncauj tshuab.
3. Eco-Friendly: Ua raws li cov qauv qis-VOC thiab qis-emissions.
4. Nqi-Efficiency: Txo kev cia siab rau cov khoom siv kim dua lossis ntxhiab tsw zoo li BDMAEE.
5. Kev Txhim Kho Ua Npuas Ncauj Zoo: Ua kom cov qauv ntawm tes zoo ib yam, porosity siab, thiab muaj zog adhesion.
Los ntawm kev koom ua ke MXC -37 rau hauv cov ntxeem tau tshuaj tsuag polyurethane ua npuas ncauj tshuab, cov chaw tsim khoom tuaj yeem tsim cov khoom zoo, eco-friendly foams nrog txo cov ntxhiab thiab txhim kho kev ua tau zoo, ua tau raws li cov kev xav tau ntawm cov niaj hnub rwb thaiv tsev thiab kev tsim kho kev lag luam.
