Daim Ntawv Thov Txoj Cai ntawmMXC-T12
MXC-T12 ua haujlwm tseem ceeb los ntawm kev txhawb nqa cov tshuaj gelling lossis polymerization ntawm polyols thiab isocyanates hauv polyurethane formulations. Cov tshuaj no ua rau muaj kev sib txuas urethane, uas ua rau polyurethane nws qhov kev ywj pheej, kev ruaj khov, thiab lub zog. Ua ib qho catalyst raws li dibutyltin, MXC-T12 muaj txiaj ntsig zoo hauv kev tswj hwm qhov sib npaug ntawm ntau theem ntawm kev tsim polyurethane, xws li cov tshuaj blowing (uas tsim cov qauv ua npuas ncauj) thiab cov tshuaj gelling (uas ua rau cov qauv ua npuas ncauj khov).
Hauv kev siv ua npuas polyurethane, MXC-T12 txhawb kev ua kom cov tshuaj gelling, ua rau muaj kev tswj hwm ntau dua ntawm kev tsim ua npuas. Qhov no ua kom ntseeg tau tias cov npuas tswj tau nws cov qauv thiab cov khoom xav tau, xws li qhov loj me ntawm cov cell, qhov ceev, thiab kev ywj pheej. Lub peev xwm ntawm cov catalyst los sib npaug cov tshuaj no yog qhov tseem ceeb heev hauv kev tsim cov npuas thaiv, qhov twg nws txhim kho cov khoom siv kho tshuab xws li lub zog tensile thiab kev tiv thaiv kev tsim kua muag. Tsis tas li ntawd, MXC-T12 ua rau lub sijhawm tsis muaj tack, uas yog qhov chaw uas qhov chaw ua npuas tsis hnov ntxhiab ntxiv lawm, yog li ua kom cov txheej txheem tsim khoom sai dua.
Cov ntawv thov ntawmMXC-T12
1. Cov Ua Npuas Ncauj Polyurethane Uas Muaj Zog Thiab Rigid
MXC-T12 siv rau hauv kev tsim cov ua npuas polyurethane uas yoog tau thiab tawv. Hauv cov ua npuas uas yoog tau, nws txhawb kom muaj cov qauv sib npaug, muab cov ua npuas nrog cov khoom siv uas tsim nyog rau kev ywj pheej thiab kev nplij siab. Cov ua npuas no feem ntau siv rau hauv rooj tog, ntaub pua chaw pw, sab hauv tsheb, thiab cov ntaub ntawv ntim khoom. Hauv cov ua npuas tawv, MXC-T12 txhim kho cov khoom rwb thaiv tsev thiab kev ruaj khov ntawm cov qauv, ua rau lawv zoo tagnrho rau kev siv hauv kev rwb thaiv tsev, tub yees, thiab kev rwb thaiv tsev hauv kev lag luam.
2. Cov nplaum thiab cov khoom siv foob ob yam
Hauv cov khoom siv polyurethane nplaum thiab sealant uas muaj ob yam khoom, MXC-T12 ua haujlwm ua tus catalyst tseem ceeb rau kev pib ua kom tawv. Tus catalyst no ua rau cov tshuaj sib xyaw ua ke ntawm polyol thiab isocyanate sai dua, ua rau tawv sai dua thiab txhim kho lub zog sib txuas. Qhov no ua rau MXC-T12 zoo tagnrho rau cov nplaum siv hauv tsheb, kev tsim kho, thiab kev ntim khoom, qhov twg qhov kev nplaum zoo thiab lub sijhawm tawv sai yog qhov tseem ceeb.
Cov txiaj ntsig ntawm MXC-T12
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev siv MXC-T12 yog nws lub peev xwm los txhim kho cov khoom siv kho tshuab ntawm cov khoom polyurethane. Los ntawm kev ua kom zoo dua qhov kev sib xyaw ua ke, cov catalyst ua kom ntseeg tau tias cov ua npuas ncauj lossis cov nplaum muaj zog, ruaj khov, thiab yooj ywm. Hauv kev siv ua npuas ncauj thaiv, MXC-T12 ua rau cov ua npuas ncauj tsis yooj yim rau kev hloov pauv thiab kev rhuav tshem, ua rau nws tsim nyog rau kev siv ua haujlwm siab.
Tsis tas li ntawd xwb, MXC-T12 ua kom cov khoom tsim tau zoo dua los ntawm kev txhawb kom kho sai dua thiab txo lub sijhawm tsis muaj kua nplaum. Qhov no tso cai rau cov chaw tsim khoom kom ua kom lawv cov txheej txheem tsim khoom sai dua yam tsis muaj kev cuam tshuam rau qhov zoo ntawm cov khoom kawg.
Xaus lus
MXC-T12, nrog nws cov dibutyltin dilaurate sib xyaw, yog ib qho tshuaj catalyst zoo heev rau ntau yam kev siv polyurethane. Nws lub peev xwm los ua kom cov tshuaj gelling sai dua, txhim kho cov khoom siv kho tshuab, thiab txo lub sijhawm kho ua rau nws yog ib qho khoom tseem ceeb hauv kev tsim cov ua npuas ncauj thiab cov khoom tawv, cov nplaum, thiab cov sealants. Los ntawm kev siv cov txiaj ntsig tshwj xeeb ntawm MXC-T12, cov chaw tsim khoom tuaj yeem txhim kho kev ua haujlwm ntawm cov khoom, ua kom cov txheej txheem tsim khoom yooj yim dua, thiab ua tau raws li qhov xav tau ntawm ntau yam kev siv hauv kev lag luam.
