Polyurethane (PU) Ua npuas ncauj tau siv dav hauv ntau yam kev lag luam vim lawv cov khoom lag luam ntau, xws li rwb thaiv tsev, thiab cov qauv kev ncaj ncees. Kev ua yeeb yam ntawm cov npaus ua npuas no yog nyob ntawm hom ua npuas ncauj raug tsim, txawm tias nws yog qhib-cell lossis catalytic system siv los tswj cov tshuaj tiv thaiv kinetics thaum ua npuas ncauj.Polyurethane catalystsUa si lub luag haujlwm tseem ceeb hauv kev kho qhov qhib-cell rau kaw-cell piv, kom ua npuas ncauj tau raws li cov kev thov. Cov ntawv sau no tshawb txog cov nyhuv ntawm polyurethane catalysts ntawm ntau hom polyurethane ua npuas thiab catalethane foams thiab li cas catalethane foams thiab li cas catalethane foams thiab li cas catalethans zoo li MXC-DPA tuaj yeem siv tau zoo rau cov khoom siv ua npuas zoo.
Hom polyurethane ua npuas ncauj
Qhib-cell ua npuas:
Qhib-Cell ua npuas ncauj muaj cov qauv uas lub hlwb lossis npuas hauv lub npo yog sib cuam tshuam nrog lawv. Cov fooams no yog lub teeb yuag, muaj cov suab zoo nqus tau cov khoom, thiab muaj feem ntau siv nyob rau hauv acoustic rwb thaiv tsev, cushioning, thiab kev thov kev pab.
-Cell Ua npuas ncauj:
Kaw cov xov tooj ntawm tes, hauv kev sib piv, muaj cov hlwb cais uas muaj roj, ua rau lawv muaj ntau dua, denser, thiab nrog cov khoom siv hluav taws xob zoo dua. Lawv feem ntau yog siv rau hauv cov ntawv thov xws li thermal rwb thaiv tsev panels, tshuaj lom neeg rwb thaiv tsev uas muaj zog, noo noo tsis kam, yog qhov tseem ceeb.
Lub luag haujlwm ntawm catalysts hauv kev tsim ua npuas
Catalysts tseem ceeb nyob rau hauv polyurethane ua npuas ntau ntau lawm thaum lawv nrawm qhov kev tawm tsam ntawm polyols thiab isocyanates, maj mam muab kev tsim ntawm qhov URethane thiab urea sib txuas. Hom thiab concentration ntawm catalysts txiav txim siab txog tus nqi ntawm ob qho tseem ceeb:
Kev tawm tsam gelation: Qhov tshuaj tiv thaiv no ua rau kev tsim cov saw polymer uas muab cov ntaub ntawv ua npuas dej.
Cov tshuaj tiv thaiv: Qhov tshuaj tiv thaiv no tsim cov roj av uas tsim kom lub foam tus qauv cell, txawm tias qhib-cell lossis kaw-cell.
Los ntawm kev sib npaug zoo ntawm ob qho kev cuam tshuam no, catalysts tuaj yeem cuam tshuam rau cov qauv xov tooj ntawm tes, ua npuas ncauj, yog li cuam tshuam seb puas muaj kev qhib lossis kaw-cell qauv.
Catalysts rau qhib-cell thiab kaw-cell ua npuas
Hauv kev qhib ua npuas ncauj-cell Catalysts nrog kev tswj kom zoo dua gelation thiab ua npuas ncauj kom ntseeg tau tias cov npuaj tsis dhau los ua kom nruj thiab tswj hwm cov khoom siv. Nyob rau hauv cov kaw tes ua npuas, gelation ceev yog feem ntau yuav tsum tau cuab cov roj hauv lub hlwb, uas ua rau lub cev tsis sib xws.
Polyurethane catalysts zoo liMXC-DPA(N - ({3- dimethylascopropyl)-}}}}} {}} MXC-DPA yog qhov tsawg-emission catalalyst muajzoo gelation thiab firmity, ua rau nws zoo tagnrho rau kev tswj hwm cov qauv ntawm tes thiab ua npuas ncauj tsim hauv ob qho tib si qhib-cell thiab kaw-cell ua npuas.
MXC-DPA hauv qhib-cell thiab kaw-cell ua npuas ncauj thov
TusMXC-DPAcatalyst feem ntau siv nyob rau hauv ether-raws stabilizers rau cov khoom siv ua npuas dej, HR) Moulders ua npuas ncauj, elastomers, thiab rigid ntim ua npuas ncauj. Lub plab qis, txuas nrog nwszoo gelation thiab firmity, Ua rau nws muaj ntau yam xaiv hauv kev kho cov qauv ua npuas ncauj.
Qhib-cell ua npuas:
Hauv cov ntawv thov xws li HR moulded mos ua npuas thiab frocellbular ua npuas, MXC-DPA txhim kho lub foam lub gelation thaum tso cai rau kev tswj hwm ntawm cov npuas dej. Qhov no ua rau cov khoom muag muag, ua npuas ncauj, hloov cov qauv qhib-ntawm tes, uas yog qhov tseem ceeb rau cov ntawv thov uas yuav tsum tau nqus cov pa, thiab nqus tau.
-Cell Ua npuas ncauj:
Rau cov neeg ua npuas ncauj kaw, xws li cov neeg siv hauv kev siv npuas dej ceev, MXC Nws cov fluicity ntseeg tau tias cov npaus puv nkaus li cov foam footh tusyees, ua rau nws haum qhov ntsuas thiab lub zog.
Hloov kho qhib-cell thiab kaw-cell piv nrog catalysts
Polyurethane tsim nyog tuaj yeem ua kom haum ntawm hom catalyst thiab Dosages, cuam tshuam qhov sib npaug ntawm cov qhib-cell thiab kaw-cell piv.MXC-DPAyog siv tau tshwj xeeb hauv kev muab cov qauv nrog kev hloov pauv kom kho cov yam ntxwv ua npuas ncauj los ntawm kev tswj hwm cov tshuaj tiv thaiv cov tshuaj tiv thaiv ntawm polyol thiab isocyanate Cheebtsam.
Piv txwv li, nce tus MXC-DPA tuaj yeem ua kom nrawm dua cov tshuaj tiv thaiv kev ua kom zoo nkauj thiab ua npuas ncauj, ntau dua ua npuas ncauj, ua npuas ncauj ntau. Hloov siab, txo cov tshuaj platuralst lossis sib txuas nrog lub tshuab catalalt tuaj yeem ua rau cov qauv qhib-cell, tsim cov tsiaj ua npuas dej uas yog softer thiab ntau ntxeem tau.
