Kev siv
4,4'-diamino-3,3 '-dichlorodiphenylmetylmethane (moca) yog cov organic sib xyaw, thiab nws cov kev thov tseem ceeb yog li nram no:
- Synthesis Cov Khoom Siv Polyurethane: MOCA yog qhov tseem ceeb saw txuas rau Polyurethane Elastomers. In the production of polyurethane, isocyanate prepolymers need to react with chain extenders to form high - molecular - weight polyurethane polymers. MOCA muaj qhov siab reactivity nrog ortocyanates, uas tuaj yeem txuas ntxiv rau polyurethane molecular, lub zog, kua muag deforance thiab lwm yam khoom ntawm cov khoom. Nws yog feem ntau siv nyob rau hauv kev tsim cov khoom siab - Load - cov kabmob roj av, cov roj hmab rollers, ntaub qhwv, metallurgy, thiab roj av. Cov khoom no yuav tsum tau hnav zoo thiab cov khoom siv tshuab tshuab.
- Tus neeg sawv cev cev rau Epoxy Resins: MOCA tuaj yeem siv los ua tus kho tus neeg sawv cev rau epoxy resins. Nws undergoes tus ntoo khaub lig - sib txuas cov tshuaj tiv thaiv nrog cov qauv epoxy los ua ib qho qauv peb - qauv network, yog li kho tau lub respoxy. Lub resins epoxy resins muaj cov khoom siv zoo, tshuaj lom neeg tiv thaiv corrosion, thiab kub tsis kam. Nws yog feem ntau siv nyob rau hauv kev tsim cov khoom siv epoxy uas muaj kev xav tau siab - kev ua tau zoo, xws li hauv cov ntaub ntawv siv hluav taws xob thiab cov tshuaj pleev pem teb. Cov khoom siv hluav taws xob yuav tsum tau tiv thaiv kev tiv thaiv sab hauv cov hluav taws xob sib xyaw ntawm cov chaw sab nraud. Lub Epoxy Resin kho nrog kev koom tes ntawm MOCA tuaj yeem muab kev sib khi thiab kev tiv thaiv kho tshuab. Epoxy pem teb txheej hlau yuav tsum muaj cov khoom xws li kev coj ua ntawm cov chaw uas muaj kev cob qhia thiab muaj chaw nres tsheb.
