Cov ua npuas dej polyurethane yooj ywm siv dav hauv ntau yam lag luam vim lawv qhov mos, ruaj khov, thiab hloov pauv tau yooj yim. Lub luag haujlwm ntawm cov tshuaj polyurethane catalysts hauv cov txheej txheem tsim khoom yog qhov tseem ceeb rau kev ua tiav cov khoom xav tau xws li qhov sib npaug ntawm qhov pore, kev ywj pheej, thiab kev nplaum zoo dua. Ob lub tshuaj catalysts tshwj xeeb, MXC-BDMA thiab MXC-70, qhia txog qhov tseem ceeb ntawm cov tshuaj catalysts xaiv zoo hauv cov qauv ua npuas dej yooj ywm.
1. MXC-BDMA (CAS 103-83-3)- Benzyl Dimethylamine Catalyst
MXC-BDMA yog ib qho tshuaj catalyst siv dav hauv polyester polyurethane ua npuas ncauj mos, polyurethane ua npuas ncauj ruaj khov, thiab daim ntawv thiab cov nplaum txheej. Txawm hais tias nws feem ntau siv rau hauv cov npuas ncauj ruaj khov, nws muaj cov txiaj ntsig zoo hauv kev tsim cov npuas ncauj ywj pheej:
- Kev Ua Kua Thaum Ntxov:MXC-BDMA ua kom muaj kev sib xyaw ua ke zoo heev thaum ntxov, ua rau cov khoom sib xyaw polyurethane ntws mus rau hauv cov pwm thiab cov qhov, uas yog qhov tseem ceeb rau kev siv ua npuas ncauj uas yoog tau.
- Cov qhov hws sib xws:Cov tshuaj catalyst pab txhawb rau kev tsim cov hlwb ua npuas dej uas muaj cov qauv zoo sib xws. Kev sib npaug ntawm cov qauv ntawm cov hlwb yog qhov tseem ceeb rau kev ua tiav cov khoom ua npuas dej sib xws xws li kev ua kom lub ncoo thiab kev ywj pheej.
- Kev Txhim Kho Kev Sib Txuas:Rau cov ntawv thov uas xav tau cov ua npuas ncauj los lo rau lub substrate, MXC-BDMA txhim kho kev lo rau, ua kom cov khoom ruaj khov thiab siv tau ntev.
2. MXC-70 (CAS 1739-84-0)- Cov tshuaj catalyst uas yog amine
MXC-70 yog lwm yam catalyst uas siv tau ntau yam, feem ntau yog siv rau hauv cov qauv ua npuas ncauj tab sis muaj qhov zoo tseem ceeb hauv kev tsim cov npuas ncauj yooj ywm, tshwj xeeb tshaj yog hauv cov npuas ncauj yooj ywm siab (HR) thiab cov blocks ester-based:
- Kev Kho thiab Kev Txhim Kho Kev Nyuaj Siab:Cov tshuaj catalyst uas muaj amine no ua rau cov txheej txheem kho kom zoo dua, txo qhov brittleness hauv cov khoom kawg, ua rau cov ua npuas ncauj yooj ywm dua thiab tsis tshua muaj kev tawg.
- Kev Txhim Kho Lub Zog Ntsuab:MXC-70 kuj tseem ua kom lub zog ntsuab ntawm cov ua npuas ncauj zoo dua, ua rau kev tuav zoo dua thaum pib tsim khoom. Cov yam ntxwv no tshwj xeeb tshaj yog rau cov ua npuas ncauj uas yooj ywm siv rau hauv kev siv tsheb thiab rooj tog, qhov twg kev ruaj khov yog qhov tseem ceeb.
- Kev Yooj Yim Rau Daim Ntawv Thov:Cov catalyst ua haujlwm zoo nrog cov carbonized polyester thiab ester-based formulations, muab kev ywj pheej hauv kev tsim cov ua npuas dej ua haujlwm siab.
Tsab xov xwm no piav qhia txog ob qho tib si catalysts ua kom zoo dua qhov ua npuas ncauj, qhia txog lawv qhov cuam tshuam rau cov qauv cell sib xws thiab kev ua kom ruaj khov, uas yog qhov tseem ceeb rau kev siv kawg xws li rooj tog, ntaub pua chaw pw, rooj zaum hauv tsheb, thiab rwb thaiv tsev.
