Cov ntaub ntawv khoom lag luam
Nitrile roj hmab yog siv dav hauv kev tsim cov khoom siv roj av ua cov roj-resistant. NBR yog cov roj hmab hluavtaws npaj los ntawm copolymerization ntawm butadiene thiab acrylonitrile. Nws yog cov roj hmab hluavtaws nrog roj zoo kuj (tshwj xeeb alkane roj) thiab kev laus tiv. Cov ntsiab lus ntawm acrylonitrile hauv NBR (%) yog 42-46, 36-41, 31-35, 25-30, 18-24 thiab lwm yam. Cov ntsiab lus siab dua ntawm acrylonitrile, qhov zoo dua cov roj tsis kam, tab sis qis dua qhov txias txias yog. Nws tuaj yeem siv tau ntev ntev hauv huab cua ntawm 120 C lossis roj ntawm 150 C. Ib qho ntxiv, nws kuj muaj cov dej tsis kam zoo, huab cua nruj thiab cov khoom sib txuas zoo heev.
