Dab tsi yog Nitrile Roj Hmab
Jun 07, 2021
Roj hmab Nitrile (NBR) yog cov copolymer tsim los ntawm polymerization ntawm acrylonitrile thiab butadiene monomers. Nws yog tsim los ntawm qhov kub thiab txias emulsion polymerization. Nws muaj cov roj ua haujlwm zoo, ua haujlwm hnyav, tiv tshav kub zoo, thiab nplaum. Cov relay muaj zog.
Roj hmab Nitrile feem ntau yog siv los ua cov khoom siv roj-resistant roj hmab. Cov ntsiab lus acrylonitrile (%) hauv cov roj hmab nitrile muaj tsib hom: 42-46, 36-41, 31-35, 25-30, 18-24. Qhov ntau acrylonitrile cov ntsiab lus, zoo dua cov roj ua haujlwm, tab sis qhov txias tsis kam txo qis raws li. Nws tuaj yeem siv tau 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 tau zoo. Siv dav hauv kev tsim khoom ntawm ntau yam roj-resistant roj hmab cov khoom, ntau yam roj-resistant gaskets, gaskets, casings, ntim tau hloov pauv, hloov tau yooj yim hoses, luam ntawv thiab zas xim cov menyuam roj hmab, cov khoom siv roj hmab, thiab lwm yam Nws tau dhau los ua qhov tsis tseem ceeb hauv kev lag luam xws li xws li tsheb, aviation, roj av, thiab luam. Cov khoom siv ywj pheej
