Corrosion tsis kam ntawm cov khoom siv rau li qub - NBR

NBR yog tau los ntawm emulsion polymerization ntawm butadiene thiab acrylonitrile, thiab NBR yog tsuas yog tsim los ntawm tsis tshua muaj kub emulsion polymerization. Cov roj ua haujlwm zoo, siab hnav tsis kam, zoo tshav kub tsis kam, muaj zog adhesion. Nws qhov tsis zoo yog qhov tsis zoo ntawm qhov kub thiab txias tsis kam, tsis zoo ozone kuj, tsis zoo rwb thaiv tsev kev ua tau zoo thiab tsis tshua muaj elasticity. NBR feem ntau yog siv los ua cov khoom siv roj hmab resistant. NBR yog ib hom roj hmab hluavtaws ua los ntawm butadiene thiab acrylonitrile. Nws yog cov roj hmab hluavtaws nrog cov roj zoo (tshwj xeeb yog cov roj alkane) thiab kev laus ua haujlwm. Acrylonitrile cov ntsiab lus (%) nyob rau hauv NBR yog 42 ~ 46, 36 ~ 41, 31 ~ 35, 25 ~ 30 thiab 18 ~ 24. Cov ntsiab lus ntawm acrylonitrile ntau dua, cov roj kuj zoo dua, tab sis qhov qis dua qhov txias tsis kam. Tsis tas li ntawd, nws muaj dej tsis kam, huab cua nruj thiab zoo adhesion. Nws yog dav siv nyob rau hauv ua ntau yam roj resistant roj hmab cov khoom, ntau yam roj resistant gaskets, gaskets, lub tes tsho, saj zawg zog ntim, saj zawg zog hose, luam ntawv thiab dyeing cots, cable roj hmab cov ntaub ntawv, thiab lwm yam. nws tau los ua ib tug indispensable elastic khoom nyob rau hauv tsheb, aviation, roj av, luam ntawv thiab lwm yam kev lag luam.
