Kev tsim khoom thiab kev ua haujlwm ntawm SPF tuaj yeem ua kom zoo dua los ntawm kev ntxiv cov tshuaj catalysts xws li MXC-37 (2-[2- (dimethylamino) ethoxy] ethanol, DMAEE)Cov tshuaj catalysts no zoo heev rau kev daws teeb meem xws li ntxhiab amine thiab kev sib npaug ntawm cov tshuaj reactivity hauv cov formulations uas muaj cov dej ntau.

1. Lub Luag Haujlwm ntawm MXC-37 hauv SPFs

MXC-37 siv tau ua tus tseem ceeb lossis tus pab txhawb kom ua npuas thiab kho cov txheej txheem:

Txo cov saj amine:Ib qho ntawm cov txiaj ntsig tseem ceeb tshaj plaws ntawmMXC-37yog nws lub peev xwm los txo qhov saj amine ib txwm muaj hauv cov khoom tiav. Cov hydrogen uas nquag ua haujlwm hauv nws cov qauv tau koom ua ke rau hauv cov polymer matrix, txo cov amines uas tseem tshuav.

Kev sib raug zoo ntawm dej siab:MXC-37 muaj cov tshuaj catalytic siab hauv cov mis uas muaj dej ua, ua rau nws yog ib qho kev xaiv dav rau cov tshuab ua npuas dej uas siv dej ua tus neeg sawv cev rau dej.

Kev siv tau yooj yim:nws tuaj yeem siv ua lub catalyst tseem ceeb 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 kev siv nyiaj.

2. Cov txiaj ntsig ntawm SPF Production

MXC-37 siv tau ua tus tseem ceeb lossis tus pab txhawb kom ua npuas thiab kho cov txheej txheem:

Txo cov saj amine:Ib qho ntawm cov txiaj ntsig tseem ceeb tshaj plaws ntawm MXC-37 yog nws lub peev xwm los txo qhov saj amine ib txwm muaj hauv cov khoom tiav. Cov hydrogen uas nquag ua haujlwm hauv nws cov qauv tau koom ua ke rau hauv cov polymer matrix, txo cov amines uas tseem tshuav.

Kev sib raug zoo ntawm dej siab:MXC-37 muaj cov tshuaj catalytic siab hauv cov mis uas muaj dej ua, ua rau nws yog ib qho kev xaiv dav rau cov tshuab ua npuas dej uas siv dej ua tus neeg sawv cev rau dej.

Kev siv tau yooj yim:nws tuaj yeem siv ua lub catalyst tseem ceeb 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 kev siv nyiaj.

3. Cov Kev Siv Tseem Ceeb ntawm Porous SPFs

Cov SPFs uas muaj qhov ntxeem tau uas MXC-37 ua rau pom cov ntawv thov hauv ntau qhov chaw:

Kev rwb thaiv tsev kub:Siv rau hauv kev tsim phab ntsa, ru tsev, thiab cov kav dej kev lag luam los txhim kho kev siv hluav taws xob.

Kev tiv thaiv suab nrov:Cov qauv qhib-cell ntawm cov SPFs porous nqus cov suab nthwv dej, ua rau lawv tsim nyog rau kev rwb thaiv tsev acoustic hauv cov chaw nyob thiab chaw lag luam.

Cov Khoom Siv Sib Tw:Cov SPFs uas muaj qhov nqus tau yog siv rau hauv cov ntaub ntawv tsim kho uas tsis hnyav, txo qhov hnyav tag nrho yam tsis muaj kev cuam tshuam rau lub zog.

Cov Khoom Siv Ntim Khoom:Lawv cov yam ntxwv uas nqus tau kev co ua rau lawv zoo tagnrho rau kev ntim khoom tiv thaiv.

4. MXC-37 ua tus Cocatalyst

Thaum siv ua ke nrog BDMAEE lossis lwm yam amine catalysts, MXC-37 muab:

Kev Tswj Xyuas Kev Ua Haujlwm Zoo Dua:Sib npaug cov tshuaj ua npuas ncauj thiab cov tshuaj gel, ua kom cov npuas ncauj zoo ib yam.

Txo Cov Tshuaj Catalyst:Txo qhov xav tau cov BDMAEE ntau dua, ua rau txuag tau nqi thiab txo cov pa phem.

Kev Ua Tau Raws Li Koj Xav Tau:Tso cai rau kev kho kom zoo ntawm lub kaw lus catalyst rau cov xwm txheej ua haujlwm tshwj xeeb thiab cov kev xav tau kev ua tau zoo.

Vim li cas ho xaiv MXC-37 rau SPFs?

1. Txo Cov Tsw Qab: Txo cov ntxhiab tsw ntawm amine hauv cov khoom kawg, txhim kho kev paub ntawm tus neeg siv.

2. Kev Siv Tau Ntau Yam: Haum rau ob qho tib si qhib-cell thiab kaw-cell ua npuas ncauj.

3. Zoo rau ib puag ncig: Ua raws li cov qauv VOC qis thiab cov pa phem tsawg.

4. Kev Siv Nyiaj Txiag Zoo: Txo kev vam khom rau cov tshuaj catalysts kim dua lossis muaj ntxhiab tsw zoo li BDMAEE.

5. Kev Ua Npuas Ncauj Zoo Dua: Xyuas kom cov qauv cell sib xws, porosity siab, thiab lo rau zoo.

Los ntawm kev siv MXC-37 rau hauv cov tshuab ua npuas dej polyurethane uas muaj qhov nqus tau, cov chaw tsim khoom tuaj yeem tsim cov npuas dej zoo, tsis muaj kuab paug nrog cov ntxhiab tsw tsawg dua thiab kev ua haujlwm zoo dua, ua tau raws li qhov xav tau ntawm kev lag luam rwb thaiv tsev thiab kev tsim kho niaj hnub.
