- Kev Hloov Pauv Tsawg thiab Tsw QabMXC-B20 pab tsim kom muaj ib puag ncig ua haujlwm huv dua, txhim kho kev nyab xeeb thiab kev xis nyob rau cov neeg ua haujlwm.
- Kev Sib Haum XeebMXC-B20 sib xws nrog ntau yam polyols ua npuas ncauj uas tawv thiab yoog tau, ua rau nws hloov tau yooj yim rau ntau hom ua npuas ncauj.
Cov ntawv thov ntawmMXC-B20hauv Polyurethane Systems
Cov yam ntxwv tshwj xeeb ntawm MXC-B20 ua rau nws haum rau ntau yam kev siv polyurethane, tshwj xeeb tshaj yog siv los hloov cov catalysts uas siv tin. Hauv qab no yog qee qhov chaw siv tseem ceeb:
- Cov Ntawv Uas Yooj YimHauv kev tsim cov ntawv polyurethane uas yoog tau, MXC-B20 muab kev ua haujlwm du thiab qeeb qeeb nrog kev tsim cov viscosity. Nws ua rau cov ua npuas ncauj kawg ua kom ruaj khov thiab muaj zog dua.
- Cov Ua Npuas Uas Muaj Qhov Ceev SiabCov ua npuas dej uas muaj zog thiab yoog tau yooj yim, siv rau hauv cov ntawv thov xws li rooj zaum thiab txaj pw, tau txais txiaj ntsig los ntawm MXC-B20 cov khoom kho tau zoo heev, ua kom ntseeg tau tias cov ua npuas dej ruaj khov thiab siv tau ntev.
- Cov Tshuab Ua Npuas Ncauj TsuagMXC-B20 yog ib qho kev xaiv zoo heev rau cov tshuab txau ua npuas ncauj vim nws cov qauv tshuaj tiv thaiv qeeb, ua rau tswj tau cov qauv txau thiab cov txheej sib sau ua ke zoo dua. Qhov no ua rau muaj cov khoom rwb thaiv tsev zoo thiab sib xws.
- Ua Npuas Ncauj MicrocellularRau cov ntawv thov tshwj xeeb xws li cov ua npuas dej me me, MXC-B20 muab kev tswj hwm cov qauv cell zoo tshaj plaws, ua kom ntseeg tau tias cov ua npuas dej ceev thiab sib xws rau cov khoom kawg xws li khau thiab cov khoom lag luam.
- Cov Txheej Txheem Ua Npuas Ncauj RigidCov ua npuas ncauj ruaj khov siv rau hauv kev rwb thaiv tsev thiab cov khoom siv hauv tsev tau txais txiaj ntsig los ntawm MXC-B20 lub peev xwm los sib npaug kev tswj hwm pem hauv ntej thiab kev kho tom qab, ua rau muaj cov khoom siv kho tshuab zoo tshaj plaws thiab kev ruaj khov hauv cov ua npuas ncauj tiav.
Lwm Txoj Hauv Kev Siv Tin-Based Catalysts
MXC-B20 ua haujlwm hloov pauv ncaj qha rau cov catalysts ua los ntawm tin, uas feem ntau cuam tshuam nrog kev txhawj xeeb txog ib puag ncig thiab kev noj qab haus huv. Los ntawm kev tshem tawm cov hlau hnyav thiab muab kev ua tau zoo sib xws, yog tias tsis zoo dua, MXC-B20 yog qhov kev xaiv zoo tshaj plaws rau cov chaw tsim khoom uas tab tom nrhiav kev tsim cov polyurethane uas tsis ua rau ib puag ncig puas tsuaj yam tsis muaj kev cuam tshuam rau qhov zoo lossis kev ua haujlwm zoo.
Xaus lus
MXC-B20 yog ib qho khoom siv uas hloov tau yooj yim, ua haujlwm tau zoo, thiab tsis ua rau ib puag ncig puas tsuaj rau cov polyurethane systems. Nws sib haum nrog cov polyols ua npuas ncauj uas ruaj khov thiab yoog tau, ua ke nrog nws qhov kev ua tau zoo tshaj plaws thiab kev tsim khoom ruaj khov, ua rau nws yog ib qho khoom siv ntxiv rau ntau yam kev siv PU. Txawm tias koj ua haujlwm rau cov npuas ncauj uas yoog tau, cov microcellular systems, lossis cov rwb thaiv tsev ruaj khov, MXC-B20 muaj kev ua tau zoo thiab kev ua tau zoo kom tau raws li koj cov kev xav tau ntau lawm.
