Hauv kev tsim cov ua npuas polyurethane, kev xaiv cov catalyst tsim nyog yog qhov tseem ceeb heev rau kev ua tiav qhov sib npaug ntawm kev ua haujlwm, kev kho, thiab kev nplaum. Cov catalyst tsis yog tsuas yog ua kom cov tshuaj tiv thaiv ntawm cov khoom polyol thiab isocyanate sai dua xwb tab sis kuj cuam tshuam rau cov khoom kawg ntawm cov ua npuas, xws li kev ywj pheej, kev ruaj khov, thiab kev nplaum rau cov khoom siv. Ntawm ntau yam catalysts muaj, MXC-R40 sawv tawm ua ib qho kev daws teeb meem siab heev uas tsim los ua kom tau raws li qhov xav tau ntawm ob qho tib si kev siv ua npuas polyurethane ywj pheej thiab tawv.
Vim li cas ho siv MXC-R40 ua ib qhoPolyurethane Catalyst?
MXC-R40 yog ib qho tshuaj amine catalyst uas tsis muaj ntxhiab tsw, tsis muaj pa phem, tsim los muab cov tshuaj ua kom du thiab tswj tau, ua kom cov npuas dej zoo sib xws rau ntau yam kev siv. Tsis zoo li cov tshuaj amine catalysts ib txwm muaj, uas yuav tsim cov ntxhiab tsw thiab pa phem heev, MXC-R40 muaj lwm txoj hauv kev zoo dua rau ib puag ncig yam tsis muaj kev cuam tshuam rau kev ua haujlwm.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm MXC-R40 yog nws lub peev xwm los txhim kho kev kho thiab kev sib txuas ntawm cov polyurethane ua npuas ncauj rau ntau yam substrates. Txawm siv rau hauv kev tsim cov npuas ncauj yooj ywm rau cov cushions thiab cov ntaub pua chaw pw lossis cov npuas ncauj ruaj khov rau cov vaj huam sib luag rwb thaiv tsev thiab cov khoom siv, MXC-R40 ua kom ntseeg tau tias cov npuas ncauj sib txuas zoo rau cov chaw uas nws kov, ua rau muaj kev ruaj khov thiab kev ua tau zoo dua.
Kev Sib Npaug ntawm Foaming thiab Gelation
MXC-R40 muaj txiaj ntsig zoo thaum siv ua ke nrog dej ua tus neeg sawv cev pab ua npuas dej. Kev sib xyaw ua ke no ua rau muaj kev sib npaug ntawm cov txheej txheem ua npuas dej thiab gelation, uas yog qhov tseem ceeb rau kev ua tiav cov qauv ua npuas dej thiab qhov ceev uas xav tau. Cov tshuaj catalyst ua rau muaj kev nce siab ntawm cov npuas dej, ua kom ntseeg tau tias cov khoom kawg muaj cov qauv cell sib xws thiab cov khoom siv kho tshuab zoo tshaj plaws.
Hauv cov ntawv thov xws li cov khoom siv hluav taws xob, cov vaj huam sib luag ruaj khov, cov ua npuas dej tsuag, thiab cov ua npuas lub thawv, qhov sib npaug no yog qhov tseem ceeb heev. Piv txwv li, hauv cov vaj huam sib luag ruaj khov, qhov sib npaug ntawm kev ua npuas dej thiab kev sib npaug ntawm cov gelation ua kom cov vaj huam sib luag muaj lub zog thiab cov khoom rwb thaiv tsev thermal tsim nyog. Hauv cov ua npuas dej ywj pheej, nws pab txhawb rau kev nplij siab thiab kev ywj pheej uas xav tau rau cov ntawv thov xws li rooj zaum thiab txaj pw.
