MXC-B20 yog ib qho catalyst uas siv bismuth los ua kom cov txheej txheem tsim polyurethane sai dua thaum xav txog kev nyab xeeb ib puag ncig. MXC-B20 yog ib qho catalyst uas siv hlau pab tau zoo heev uas ua haujlwm ua ke nrog tertiary amines los ua kom cov tshuaj tiv thaiv ntawm isocyanates thiab polyols sai dua, ua kom cov tshuaj kho sai dua thiab txhim kho kev ua haujlwm ntawm cov khoom. Nws tsis muaj mercury, lead thiab dibutyltin, ua rau nws muaj kev nyab xeeb dua thiab ruaj khov dua li cov catalysts uas siv tin.
Dab tsi yog Bismuth-Based Catalyst?
Ib qho kev xaiv uas muaj kev nyab xeeb dua thiab zoo dua rau ib puag ncig piv rau cov tshuaj catalysts uas muaj tin, bismuth catalysts yog cov tshuaj catalysts uas ua haujlwm tau zoo thiab tau lees paub tias yog cov tshuaj catalysts gel ceev uas siv tau rau ntau yam kev siv, suav nrog cov tshuaj pleev xim, cov nplaum, cov sealants thiab polyurethane elastomers. Cov nocov tshuaj catalystsua lub luag haujlwm tseem ceeb hauv kev pab txhawb kev ua haujlwm ntawm polyurethane, ua kom lub sijhawm kho sai thiab cov khoom tiav ruaj khov. Thaum kev lag luam polyurethane txav mus rau cov kev daws teeb meem uas zoo rau ib puag ncig, cov tshuaj bismuth catalysts xws li MXC-B20 tau siv dav.
Yuav ua li casMXC-B20Ua haujlwm?
Lub MXC-B20 muaj kev ua tau zoo heev hauv ob qho tib si tshuaj tsuag ua npuas ncauj thiab cov txheej txheem ua npuas ncauj ruaj khov. Thaum siv tsawg, nws ua rau muaj kev sib sau ua ke ntawm cov viscosity qeeb, ua rau lub sijhawm ua haujlwm ntev dua thaum txhawb kev kho kom zoo tom qab. Qhov sib npaug no tso cai rau kev tswj hwm thiab kev ywj pheej ntau dua hauv cov txheej txheem tsim khoom, yog li ua kom ntseeg tau tias cov khoom polyurethane muaj qhov tsis zoo tsawg tshaj plaws thiab zoo dua. MXC-B20 yog tus cwj pwm los ntawm kev hloov pauv tsawg thiab tsawg lossis tsis muaj ntxhiab, ua rau nws yooj yim rau kev tuav hauv ib puag ncig tsim khoom.
Kev Sib Tw thiab Kev Siv Tau Ntau Yam
MXC-B20 siv tau nrog cov polyols ua npuas ncauj tawv thiab mos thiab yog qhov kev xaiv zoo rau ntau yam kev siv ua npuas ncauj. Nws siv tau zoo hauv cov npuas ncauj thaiv yooj ywm, cov npuas ncauj ceev ceev, cov npuas ncauj microcellular, cov npuas dej tsuag thiab cov tshuab ua npuas ncauj ruaj khov. Qhov kev hloov pauv no ua rau cov chaw tsim khoom ua tiav kev ua tau zoo hauv ntau yam khoom, los ntawm cov ntaub ntawv rwb thaiv tsev mus rau cov khoom siv hauv tsheb.
Ib Txoj Kev Xaiv Uas Muaj Kev Nyab Xeeb Dua, Muaj Kev Ruaj Ntseg Dua
Hauv kev ua lag luam uas tsom mus rau kev ruaj khov ntau zuj zus, cov tshuaj catalysts gel uas ua los ntawm bismuth xws li MXC-B20 tau hloov cov tshuaj catalysts uas ua los ntawm tin nrog cov tshuaj bismuth uas ua rau muaj kev ua haujlwm siab. Cov chaw tsim khoom tuaj yeem cia siab rau MXC-B20 los tsim cov khoom polyurethane zoo kom tau raws li qhov xav tau ntawm kev daws teeb meem uas muaj kev nyab xeeb dua thiab ruaj khov dua.
Yog xav paub ntxiv txog MXC-B20 thiab nws yuav ua li cas thiaj txhim kho koj cov polyurethane ntau lawm, hu rau peb hnub no vim peb muaj txoj kev ua haujlwm zoo tshaj plaws thiab pab neeg mob siab rau hloov kho cov khoom catalyst rau kev ua lag luam zoo tshaj plaws.
