Cov xwm txheej tam sim no ntawm cov txheej txheem rwb thaiv tsev ua npuas dej
Cov khoom siv ua npuas dej polyurethane txau tau dhau los ua cov thev naus laus zis tseem ceeb ntawm cov haujlwm txuag hluav taws xob niaj hnub no. Nrog nws cov kev ua tau zoo ntawm kev rwb thaiv tsev kub thiab cov yam ntxwv tsim kho tsis muaj kev sib txhuam, nws nyob hauv txoj haujlwm tseem ceeb hauv kev lag luam rwb thaiv tsev thoob ntiaj teb. Cov thev naus laus zis tsim kho no txau cov isocyanate thiab polyol sib xyaw ncaj qha rau ntawm qhov chaw ntawm lub substrate, thiab teb sai sai hauv qab kev ua haujlwm ntawm cov catalyst los tsim cov qauv ua npuas dej kaw lossis qhib kom ua tiav cov txiaj ntsig rwb thaiv tsev zoo heev.
Cov ua npuas dej kaw-cell tau dhau los ua qhov kev daws teeb meem zoo tshaj plaws rau kev rwb thaiv tsev ntawm phab ntsa sab nraud, ru tsev thiab chaw cia khoom txias vim nws qhov kev ua tau zoo heev ntawm kev rwb thaiv tsev (thermal conductivity 0.020-0.028W / (m · K)) thiab cov yam ntxwv ntawm kev txhawb nqa cov qauv. Qhov tseem ceeb rau kev ua tiav qhov kev ua tau zoo zoo no yog nyob rau hauv kev tswj hwm qhov tseeb ntawm lub kaw lus catalyst rau cov tshuaj tiv thaiv trimerization ntawm polyisocyanurate.
Kev tshawb pom tshiab ntawmMXC-TMAcov tshuaj ua kom lub cev muaj zog
MXC-TMA catalyst yog ib tiam tshiab ntawm trimerization catalyst tsim tshwj xeeb rau cov tshuaj tsuag ua npuas ncauj. Nws cov mis tshiab daws tau ntau yam teeb meem kev siv tshuab ntawm cov tshuaj catalysts potassium ib txwm muaj thaum lub sijhawm tsim kho. Cov khoom ua kua tsis muaj xim rau daj daj no ua tiav kev tswj hwm qhov kev ua haujlwm ntawm polyurethane los ntawm nws cov tshuaj lom neeg tshwj xeeb.
Hais txog kev tswj cov tshuaj tiv thaiv, MXC-TMA muab cov kab nkhaus nce siab sib npaug thiab tswj tau zoo dua, txo qhov tshwm sim ntawm kev sagging thaum lub sijhawm txau tshuaj. Nws cov khoom xyaw tshwj xeeb sib npaug cov tshuaj tiv thaiv foaming thiab gelling, zam kev tsim cov qhov tsis zoo ntawm qhov chaw, thaum ua kom qhov ceev ntawm kev kho thiab luv lub sijhawm tsim kho.
Kev ua kom cov kua dej zoo dua yog lwm qhov txiaj ntsig tseem ceeb ntawm MXC-TMA. Cov khoom no tuaj yeem txhim kho cov yam ntxwv ntawm cov mis uas muaj cov khoom khov kho thiab ua kom cov npuas dej sib npaug zoo dua, uas yog qhov tsim nyog rau kev txau cov khoom siv rau ntawm cov duab geometric nyuaj. Piv nrog cov catalysts uas muaj potassium, MXC-TMA tseem tuaj yeem ua haujlwm zoo hauv qhov chaw kub qis, ua rau kev siv cov khoom siv kub ntau dua.
Cov ntsiab cai kev siv tshuab thiab cov txiaj ntsig ntawm kev ua tau zoo
MXC-TMAtxhawb nqa cov tshuaj tiv thaiv trimerization ntawm isocyanates los tsim cov qauv isocyanurate ruaj khov. Cov qauv tshuaj tshwj xeeb no muab peb qhov zoo rau cov khoom ua npuas ncauj: kev ruaj khov thermal zoo dua, qhov kub ntawm kev lwj tuaj yeem nce ntxiv los ntawm 30-50 ℃; kev tiv thaiv hluav taws zoo heev, cov pa oxygen tuaj yeem ncav cuag 26-28; kev ruaj khov zoo heev, kev hloov pauv ntim tswj tau hauv 1%.
Hauv kev siv ua haujlwm, peb pom zoo kom siv MXC-TMA ua ke nrog cov tshuaj amine catalysts, nrog rau qhov sib piv tswj tau ntawm 30-50% ntawm tag nrho cov tshuaj catalyst. Cov khoom muaj qhov kub thiab txias ua haujlwm dav (15-35 ℃), sib xws nrog ntau yam tshuaj ua npuas ncauj xws li HFC-245fa thiab HFO-1234ze, thiab siv tau ua ke nrog feem ntau polyether/polyester polyols thiab cov tshuaj tiv thaiv hluav taws.
