NBR O Nplhaib Rau Cov Ntawv Thov Dav
NBR (Nitrile), tshuaj, yog lub copolymer ntawm butadiene thiab acrylonitrile. Acrylonitrile cov ntsiab lus sib txawv hauv cov khoom lag luam tawm los ntawm 18% mus rau 50%. Raws li cov ntsiab lus NBR nce ntxiv, tiv taus cov roj hauv paus roj thiab cov roj hydrocarbon ntxiv nce, tab sis kub tsis hloov qis dua.

Raws li cov ntsiab lus NBR nce ntxiv, tiv taus cov roj hauv paus roj thiab cov roj hydrocarbon ntxiv nce, tab sis kub tsis hloov qis dua.
Txog NBR
Vim nws ua tau zoo heev rau cov khoom siv roj av, thiab nws lub peev xwm yuav tsum sib xyaw rau kev pabcuam ntau dua li qhov kub thiab txias ntawm -35 ° C rau +120 ° C (-30 ° F rau +250 ° F), Nitrile / NBR yog qhov feem ntau dav siv elastomer hauv kev lag luam tsiaj hiav txwv hnub no. Kuj tseem muaj ntau cov tub rog roj hmab cov lus qhia tshwj xeeb rau roj thiab roj resistant O-rings yuav tsum muaj nitrile nyob sib txuas.
Nws yuav tsum hais tias kom tau txais qhov ua tau zoo rau qhov kub tsawg, feem ntau nws yuav tsum tau txi qee qhov kub tsis kam. Nitrile tebchaw ua tau zoo tshaj rau cov feem ntau elastomers nrog kev hais txog compression teeb, tsim kua muag, thiab puas ua haujlwm. Nitrile tebchaw tsis muaj cov tshuaj tiv thaiv zoo rau ozone, tshav ntuj, lossis huab cua. Lawv yuav tsum tsis txhob cia nyob ze cov cav hluav taws xob lossis lwm yam khoom siv roj ozone.
Cov ntawv thov NBR
NBR ntu yuav tsum khaws cia ntawm lub hnub ncaj qha. Txawm li cas los xij, qhov no tuaj yeem hloov kho los ntawm kev sib xyaw. NBR yog cov khoom txheem rau cov tshuab nqus dej thiab cov hlab ntsws. NBR tiv thaiv cov kua roj-ua kua roj, cov rog, tsiaj thiab zaub roj, nplaim taws rov qab ua kua (HFA, HFB, HFC), roj, dej, thiab huab cua. Qhov tshwj xeeb qis-kub sib xyaw ua ke muaj rau cov ntxhia roj-ua kua. Los ntawm hydrogenation, carboxylic acid ntxiv, lossis PVC blending, nitrile polymer tuaj yeem ua tau raws li ntau cov kev xav tau ntawm lub cev lossis tshuaj. Qhov zoo ntawm Nitrile-tebchaw nyob ntawm qhov feem pua ntawm acrylonitrile hauv lub hauv paus polymer.
