Kev lag luam polyurethane tau siv cov tshuaj catalysts uas muaj tin ntev lawm vim lawv lub luag haujlwm zoo hauv kev ua kom cov tshuaj tiv thaiv thiab cov txheej txheem kho kom sai. Txawm li cas los xij, kev txhawj xeeb txog ib puag ncig thiab kev noj qab haus huv tau ua rau muaj kev tshawb nrhiav lwm txoj hauv kev zoo. Ib qho kev hloov pauv zoo yog MXC-B20, uas yog bismuth carboxylate cataly...
Cov tshuaj polyurethane catalysts, xws li MXC-T, ua lub luag haujlwm tseem ceeb hauv kev tsim ntau hom polyurethane ua npuas ncauj, suav nrog polyether ua npuas ncauj mos, ua npuas ncauj pwm, ua npuas ncauj semi-rigid, thiab ua npuas ncauj nruj. Ntawm cov no, ua npuas ncauj polyurethane mos sawv tawm rau nws daim ntawv thov dav dav thoob plaws ntau yam kev lag luam...
