Polyurethane hloov tau ua npuasy yog siv dav hauv ntau yam kev lag luam vim lawv qhov muag muag vim lawv qhov muag muag, kav ntev, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility, thiab versatility. Lub luag haujlwm ntawm Polyurethane catalysts hauv cov txheej txheem ntau lawm yog qhov tseem ceeb rau kev ua tiav cov khoom lag luam zoo li pore cov kev sib dhos, kev siv zog, thiab txhim kho adhesion. Ob lub catalysts tshwj xeeb, MXC-BDMA thiab MxC {1}}}}}}}}, ua kom pom qhov tseem ceeb ntawm cov qauv ua npuas ncauj.
1. MXC-BDMA (CAS 103-83-3)- Benzyl dimethylamine catalyst
MXC-BDMA yog cov catalyst dav nyob rau hauv polyester polyurethane loj lub mos mos ua npuas ncauj, polyurethane rigid ua npuas ncauj, thiab cov ntawv nplaum thiab cov nplaum nplaum. Thaum nws yog qhov tseem ceeb siv rau hauv cov npuas pob ua npuas, nws tau tseem ceeb rau cov txiaj ntsig zoo hauv kev tsim khoom ua npuas ua npuas ua ke:
Thaum ntxov Fluidity:MXC-BDMA paub meej txog fluent fluently, tso cai rau polyurethane sib xyaw kom ntws ruaj khov rau pwm thiab cov kab noj hniav uas yog qhov tseem ceeb rau cov ntawv thov siv tau ua npuas ncauj.
Cov pores cev ris tsho hnav:Cov catalyst pab txhawb rau kev tsim cov khaub ncaws hnav, cov qauv ua npuas ncauj. Kev sib txuam ntawm cov qauv xov tooj ntawm tes yog qhov tseem ceeb rau kev ua npuas ncauj ua npuas dej xws li cushioning thiab kev rau siab.
Adhesion txhim kho:Rau cov ntawv thov uas yuav tsum tau ua npuas ncauj rau kev sib raug zoo, MXC-BDMA txhim kho adhesion, kom muaj cov khoom ruaj khov thiab ruaj khov.
2. MXC -70 (CAS 1739-84-0)- amine-based catalyst
MXC -70} Puas muaj lwm yam tseem ceeb hauv kev tsim txiaj, HR) flexs foams thiab ester-raws thaiv:
Kho thiab Brittleness txhim kho:Qhov no amine-based catalyst txhim kho cov txheej txheem kev kho, ua kom zoo nkauj nyob rau hauv cov khoom kawg, ua npuas ncauj ntxiv thiab tsis tshua muaj kev tawg.
Lub zog ntsuab ntxiv:MXC -70}}}}}}} Txawm txhim kho lub foam lub zog ntsuab, muab kev tuav zoo dua thaum lub sijhawm thaum ntxov ntawm kev tsim khoom. Cov cuab yeej no yog qhov tseem ceeb rau cov ua npuas ncauj siv tau siv hauv cov ntaub ntawv thiab rooj tog zaum, qhov twg ruaj khov.
Kev Siv Khoom Siv Yooj Yim:Cov catalyst ua haujlwm zoo nrog carbonized polyester thiab ester-based formulations, muab hloov pauv ntawm kev tsim cov khoom siv siab yooj yim.
Kab lus no tuaj yeem piav qhia txog tias kev ua kom zoo nkauj ua npuas ncauj, uas yog qhov ua kom zoo rau cov khoom siv xws li rooj tog, kev txaj pw, thiab rwb thaiv tsev.
