Polyurethane elastomer yog ib hom khoom siv dav dav, nws muaj kev ywj pheej zoo, ruaj khov thiab tiv taus kev hnav, yog li nws tau siv dav hauv txhua qhov chaw ntawm lub neej. Ib qho ntawm cov ntsiab lus tseem ceeb hauv kev tsim cov polyurethane elastomers yog kev siv cov catalysts uas ua kom cov tshuaj tiv thaiv sai dua thaum lub sijhawm tsim cov khoom kawg. Cov catalysts no yog qhov tseem ceeb rau kev tswj cov txheej txheem polymerization, xyuas kom meej tias cov khoom xav tau ntawm elastomer tau ua tiav. Ntawm ntau yam catalysts muaj, MXC-A33 muaj cov khoom sib xyaw tshwj xeeb uas tuaj yeem siv rau hauv ntau yam polyurethane ua npuas ncauj thiab elastomers.
Yog dab tsiMXC-A33?
MXC-A33 yog ib qho tshuaj polyurethane uas ua rau cov tshuaj tiv thaiv ntawm polyols thiab isocyanates zoo dua, uas yog cov khoom tseem ceeb ntawm cov khoom siv polyurethane. Cov tshuaj catalyst no muaj 33% TEDA (triethylene diamine) thiab 67% DPG (monoconjugated dipropylene glycol). Cov tshuaj no muab kev ua tau zoo tshaj plaws hauv kev tsim cov polyurethane ua npuas ncauj thiab elastomers.
- TEDA (Triethylenediamine): Ib qho catalyst tertiary amine zoo heev uas txhawb nqa cov tshuaj gelling ntawm cov hydroxyl thiab isocyanate pawg.
- DPG (Monoconjugated Dipropylene Glycol): Ib qho tshuaj uas pab txo qhov viscosity thiab txhim kho kev sib tov ntawm cov ntaub ntawv, ua kom cov txheej txheem tshuaj tiv thaiv du.
Daim ntawv thov hauv Polyurethane Elastomers
MXC-A33 siv dav hauv kev tsim cov polyurethane elastomers vim nws cov nyhuv catalytic sib npaug, uas ua kom ntseeg tau tias cov tshuaj tiv thaiv polymerization tshwm sim ntawm qhov nrawm tswj. Qhov kev tswj hwm reactivity no yog qhov tseem ceeb rau kev tsim cov elastomers nrog cov khoom siv kho tshuab xav tau xws li elasticity, lub zog tensile thiab kev tiv thaiv hnav.
Cov tshuaj catalyst txhawb kev tsim cov qauv polymer sib txuas ua ke, uas tuaj yeem ua tau raws li kev ua tau zoo ntawm elastomers hauv cov ntawv thov uas xav tau ntau. Polyurethane elastomers ua los ntawm MXC-A33 feem ntau siv rau hauv cov khoom siv tsheb, cov menyuam dov hauv kev lag luam, thiab cov foob ua haujlwm siab, uas ua rau muaj kev xav tau ntau rau lawv qhov ruaj khov thiab elasticity.
