Ua npuas dej polyurethane yog ib yam khoom siv ua npuas dej uas siv tau ntau yam thiab feem ntau siv, uas muaj ntau yam siv tau hauv ntau yam lag luam. Nws siv rau hauv feem ntau ntawm cov rooj tog sab hauv tsev hauv Tebchaws Meskas thiab txawv teb chaws, tshwj xeeb tshaj yog hauv kev lag luam rooj tog, qhov twg muaj ntau yam qhov ceev thiab qhov tawv sib txawv ua rau nws haum rau ntau yam kev siv, feem ntau siv rau hauv cov ntaub thaiv, txaj pw, ncoo thiab rwb thaiv tsev. Ua npuas dej polyurethane qhib-cell, tshwj xeeb tshaj yog, yog mos, yoog tau thiab sib dua, ua rau nws yog thawj qhov kev xaiv rau cov khoom uas xav tau kev nplij siab thiab kev ruaj khov. Qhov xwm txheej ntawm cov npuas dej no ua rau nws cov khoom rwb thaiv tsev kub thiab suab nrov zoo dua, ua rau nws haum rau ntau yam kev siv los ntawm kev kho kom zoo nkauj sab hauv tsev mus rau cov ntaub ntawv rwb thaiv tsev.
Cov catalysts xws liMXC-A33thiab MXC-T ua lub luag haujlwm tseem ceeb hauv kev tsim cov ua npuas ncauj polyurethane qhib. Cov catalysts no pab txhawb cov txheej txheem ua npuas ncauj los ntawm kev ua kom cov tshuaj lom neeg sai dua ntawm isocyanates, xws li toluene diisocyanate lossis TDI, thiab polyols. Lawv lub luag haujlwm yog xyuas kom meej tias cov ua npuas ncauj tsim nws cov qauv qhib-cell, ua rau cov khoom siv uas ua pa tau thiab ywj.
MXC-A33 siv tau rau cov npuas mos, tawv thiab ib nrab tawv. Nws kuj tseem yaj tau lwm cov kuab tshuaj xws li MEG, DEG, BDO, thiab lwm yam, rau ntau yam kev siv sib txawv.
MXC-Tsiv los tsim cov polyether flexible foams, molded foams, semi-rigid foams thiab rigid foams. Nws yog siv tshwj xeeb hauv tsheb.
Cov ua npuas ncauj polyurethane qhib-cell siv dav hauv cov rooj tog zaum sab hauv tsev thiab sab nraum zoov, cov txaj pw ua npuas ncauj nco, cov ncoo zaum thiab txawm tias cov ntim khoom kho mob vim nws muaj peev xwm haum rau lub cev thiab muab kev nplij siab. Nws qhov mos mos thiab kev ywj pheej, ua ke nrog cov khoom zoo heev rau kev rwb thaiv tsev kub thiab suab, ua rau nws yog qhov kev xaiv nrov rau kev rwb thaiv tsev txuag hluav taws xob hauv cov tsev.
Hauv kev xaus lus, kev siv cov tshuaj polyurethane catalysts xws li MXC-A33 thiab MXC-T hauv kev tsim cov foams qhib-cell txhim kho kev ua haujlwm ua npuas ncauj, xyuas kom meej tias cov khoom kawg ua tau raws li cov yam ntxwv xav tau rau ntau yam kev siv xws li rooj tog thiab cov ntaub ntawv rwb thaiv tsev. Mingxu Chemical Company tau tsim cov tshuaj polyurethane catalysts rau ntau tshaj 20 xyoo, peb muaj txoj kev ua haujlwm zoo tshaj plaws thiab pab pawg kws tshaj lij los txhim kho thiab hloov kho cov khoom catalyst rau kev ua lag luam, muaj ntau qhov chaw, txais tos cov neeg siv khoom tuaj sab laj.
