Mingxu Chemicals yog tus neeg muag khoom hauv kev lag luam ntawm polyurethane catalysts, thiab tam sim no peb qhia txog kev ua tau ntau yam thiab kev siv yooj yim ntawm polyurethane ua npuas mos thiab lub luag haujlwm ntawm pebMXC-A1ua rau lawv cov khoom tsim tawm. Cov ua npuas dej mos polyurethane siv dav vim lawv qhov kev hloov pauv tau yooj yim thiab elasticity, txhawb nqa kev lag luam xws li rooj tog, tsheb, kis las, kev kho mob thiab kev ntim khoom. Nrog cov khoom zoo dua xws li cushioning, suab rwb thaiv tsev thiab lim dej, cov ua npuas dej mos yog cov khoom siv xaiv rau kev siv ua haujlwm siab.
Cov ua npuas dej mos polyurethane yog tsim los ntawm kev sib xyaw tshuaj ntawm diisocyanates thiab polyols, ob qho tib si feem ntau yog los ntawm roj av nyoos. Tsis tas li ntawd, polyols tuaj yeem tau txais los ntawm cov roj ntuj tsim dua tshiab, muab cov kev xaiv tsim khoom ruaj khov. Thaum ua ke, diisocyanate thiab polyol sib xyaw ua ke los ua ib lub npuas dej nrog cov qauv honeycomb. Cov qauv no muaj kev sib zog, elasticity thiab cov khoom zoo heev, ua rau nws zoo tagnrho rau kev siv hauv rooj tog, ntaub pua chaw pw, rooj zaum tsheb, khoom siv kis las, khoom siv kho mob, ntim khoom, khau thiab ntaub pua plag MATS. Cov qauv ntawm cov ua npuas dej mos polyurethane kuj txhim kho cov suab rwb thaiv tsev thiab cov khoom lim dej, ntxiv nthuav nws cov txiaj ntsig hauv ntau qhov chaw.
Tus yuam sij rau kev ua kom cov ua npuas dej zoo thiab cov qauv ruaj khov yog kev siv cov tshuaj catalysts thiab cov khoom ntxiv tshwj xeeb. Peb cov tshuaj catalyst MXC-A1, hu uaBDMAEE(CAS tus lej: 3033-62-3) lossis N,N,N',N' -tetramethyl-2,2′-oxybis (ethylamine), yog ib qho tshuaj catalyst tertiary amine uas muaj zog heev, feem ntau yog siv rau hauv kev tsim cov khoom ua npuas ncauj uas yoog tau, tshwj xeeb tshaj yog rau kev tsim cov khoom rov qab siab, RIM. Ua npuas ncauj Polyurethane yog tsim los ntawm kev sib xyaw ntawm diisocyanate thiab polyol. Cov kua tsis muaj xim rau me ntsis daj no txhawb nqa urea (dej-isocyanate) cov tshuaj tiv thaiv hauv cov ua npuas ncauj polyurethane mos thiab tawv, muab kev ua haujlwm catalytic thiab kev xaiv thaum lub sijhawm ua npuas ncauj.
Cov yam ntxwv tshwj xeeb ntawm MXC-A1 ua rau nws tsim nyog rau kev tsim yuav luag txhua hom ua npuas ncauj uas yoog tau, tshwj xeeb tshaj yog cov khoom lag luam uas rov qab zoo thiab cov ntawv thov Reaction Injection Molding (RIM). Los ntawm kev hloov qhov loj ntawm cov npuas thaum lub sijhawm ua tshuaj tiv thaiv ntawm polyols thiab isocyanates, cov tshuaj amine catalysts thiab surfactants tso cai rau kev hloov kho qhov ceev thiab kev ruaj khov ntawm cov npuas ncauj. Lwm cov khoom ntxiv xws li cov tshuaj tiv thaiv hluav taws thiab cov neeg sawv cev bacteriostatic ntxiv txhim kho qhov ntau ntawm cov npuas ncauj siv, tshwj xeeb tshaj yog hauv kev lag luam aerospace, tsheb, sab nraum zoov, thiab marine.
Nrog peb cov tshuaj catalyst MXC-A1, cov chaw tsim khoom ua npuas ncauj ywj pheej tuaj yeem ua tiav kev tsim khoom zoo, kev ua npuas ncauj zoo sib xws thiab kev siv ntau yam. Yog xav paub ntxiv txog MXC-A1 thiab lwm cov tshuaj catalysts, thov hu rau peb kom paub seb peb cov tshuaj catalysts tuaj yeem ua tau raws li koj cov kev xav tau ntawm kev tsim cov npuas ncauj polyurethane ywj pheej.
