NBR feem ntau yog tsim los ntawm qhov kub thiab txias emulsion polymerization txoj kev, nrog rau cov roj zoo heev, muaj zog abrasion tsis kam, zoo kub tsis kam thiab muaj zog adhesion.Nws qhov tsis zoo yog qhov tsis zoo ntawm qhov kub thiab txias tsis kam, tsis zoo ozone tsis kam, tsis zoo rwb thaiv tsev kev ua haujlwm, thiab qis elasticity me ntsis.NBR feem ntau yog siv rau hauv kev tsim cov khoom siv roj hmab, ntau yam roj-resistant gaskets, gaskets, lub tes tsho, mos ntim, mos hose, luam ntawv thiab dyeing rollers, cable roj hmab cov ntaub ntawv, thiab lwm yam. Nws tau dhau los ua cov khoom tseem ceeb elastic. nyob rau hauv automotive, aviation, roj av, luam ntawv thiab lwm yam lag luam.
NBR feem ntau yog tsim los ntawm qhov kub thiab txias emulsion polymerization txoj kev, nrog rau cov roj zoo heev, hnav tsis kam, zoo kub tsis kam thiab muaj zog adhesion.Nws qhov tsis zoo yog qhov tsis zoo ntawm qhov kub thiab txias tsis kam, tsis zoo ozone tsis kam, tsis zoo rwb thaiv tsev kev ua haujlwm, thiab qis elasticity me ntsis.NBR feem ntau yog siv rau hauv kev tsim cov khoom siv roj hmab-resistant, ntau yam roj-resistant gaskets, gaskets, lub tes tsho, mos ntim, mos roj hmab raj, luam ntawv thiab dyeing rollers, cable roj hmab cov ntaub ntawv, thiab lwm yam. Nws tau dhau los ua ib qho tseem ceeb elastic. cov khoom siv hauv tsheb, aviation, roj av, luam ntawv thiab lwm yam lag luam.
NBR muaj roj zoo heev.Butadiene monomer tuaj yeem ua copolymerized rau hauv peb txoj kab sib txawv: cis, trans thiab 1,2-焼 pawg.Tus qauv NBR feem ntau yog hais txog 78% trans.Vim muaj cov cyano nyob rau hauv NBR molecular saw qauv, cov roj kuj (xws li, rau cov roj ntxhia, kua roj, tsiaj thiab zaub roj, thiab cov kuab tshuaj) zoo dua li cov roj hmab ntuj, neoprene, thiab styrene-butadiene roj hmab.Piv nrog rau lwm cov roj hmab, NBR muaj qhov dav ntawm qhov kev pabcuam kub, nws qhov kub thiab txias yog 120oC.Lub caij no, NBR muaj qhov kub thiab txias tsis kam, qhov kub hloov pauv iav qis tshaj plaws tuaj yeem ncav cuag -55oC.
NBR muaj tshuaj lom neeg ruaj khov thiab kev ua haujlwm zoo.Raws li nws cov txheeb ze ceev nce nrog cov ntsiab lus ntawm propylene nitrile nyob rau hauv nws cov qauv, lub vulcanization ceev yog ceev thiab lub tensile zog kev ua tau zoo dua, tab sis cov resilience kev ua tau zoo txo thiab qhov txias kuj yuav tsis zoo.NBR yog cov roj hmab semiconductor vim tias cyano hauv NBR tau yooj yim polarized los ntawm hluav taws xob teb, yog li cov cuab yeej dielectric txo.nBR tuaj yeem muab faib ua 5 pawg ntawm ultra-siab, siab, nruab nrab-siab, nruab nrab thiab qis propylene nitrile raws li qib ntawm ACN cov ntsiab lus.Cov txheej txheem ntau lawm yog muab faib ua cov txheej txheem nruam thiab sib cuam tshuam polymerization.Nruam txoj kev polymerization feem ntau yog siv rau ob peb ntau yam thiab loj ntau lawm ntim ntau lawm nrog tsawg noj.Intermittent polymerization txoj kev yog tsim rau ntau ntau yam thiab me me batch ntau lawm, polymerization kos npe siv ib tug tsawg tus nqi siab ntawm engineering thiab kev tsim kho.Txog tam sim no, nws tsis pom qhov sib txawv ntawm kev sib hloov.
Txawm hais tias NBR muaj lub cev zoo thiab kev ua haujlwm zoo thiab kev ua haujlwm zoo, tab sis lub sijhawm ntev hauv cov roj av acidic thiab kub siab (150oC) ib puag ncig tsis zoo li kev ua haujlwm ntawm fluorine-zoo li roj hmab thiab propionic acid txias roj hmab, vim li no cov tuam txhab German. , Canadian tuam txhab thiab Japanese tuam txhab uas muag los txhim kho kev ua tau zoo ntawm hydrogenated nitrile roj hmab (HNBR).Tsis tas li ntawd, peb kuj tau tsim NBR nrog kev ua haujlwm txias txias thiab siab purity thiab XNBR.
