Hauv kev lag luam polyurethane niaj hnub no, kev ua tau zoo, kev nyab xeeb, thiab kev ruaj khov yog cov tsav tsheb tseem ceeb rau kev tsim kho tshiab. Thaum cov kev cai nruj dua thiab cov chaw tsim khoom nrhiav kev tshem tawm cov hlau hnyav ntawm lawv cov qauv, MXC-B20 tshwm sim ua cov tshuaj polyurethane tiam tom ntej uas ua tau raws li cov kev xav tau no yam tsis muaj kev cuam tshuam rau kev ua tau zoo.
Yog Dab TsiMXC-B20?
MXC-B20 yog ib qho catalyst bismuth hlau carboxylate uas tsim los ua lwm txoj hauv kev ua haujlwm siab rau cov catalysts uas muaj tin xws li dibutyltin dilaurate. Sib npaug rau MB20, MXC-B20 yog tsim los ua haujlwm synergistically nrog tertiary amine catalysts los txhawb cov tshuaj polyurethane thiab kev kho.
Tsis zoo li cov tshuaj catalysts ib txwm muaj uas yuav tso tawm cov ntxhiab tsw phem lossis muaj cov hlau phom sij xws li mercury, lead, lossis tin, MXC-B20 yog ib qho kev xaiv uas tsis muaj ntxhiab tsw, tsis hloov pauv ntau, thiab tsis ua rau ib puag ncig puas tsuaj, pab cov tuam txhab tsim khoom ua tiav ob qho tib si lub hom phiaj kev siv tshuab thiab kev cai lij choj.
Cov yam ntxwv tseem ceeb ntawmMXC-B20
✅ Tsis Muaj Tshuaj Lom: Tsis muaj mercury, lead, thiab dibutyltin.
✅ Tsis Muaj Tsw Qab: Zoo tagnrho rau cov tshuaj uas tswj tau tsw qab tseem ceeb heev.
✅ Kev Hloov Pauv Qis: Txhim kho kev nyab xeeb hauv chaw ua haujlwm thiab kev ruaj khov ntawm cov khoom.
✅ Sib xws nrog ntau lub tshuab: Ua haujlwm zoo nrog cov polyols ua npuas ncauj thiab yoog tau.
✅ Cov Qauv Tshuaj Tiv Thaiv Zoo Tshaj Plaws: Muab kev ncua sijhawm pem hauv ntej nrog kev kho kom zoo tom qab, zoo tagnrho rau cov qauv sib xyaw.
