Acrylonitrile rau NBR
Acrylonitrile rau NBR,
Acrylonitrile rau NBR Nitrile, Acrylonitrile rau Acrylonitrile Butadiene Rubber, Acrylonitrile rau Nitrile roj hmab,
NBR (Nitrile), tshuaj, yog ib copolymer ntawm butadiene thiab acrylonitrile.Acrylonitrile cov ntsiab lus sib txawv hauv cov khoom lag luam los ntawm 18% mus rau 50%.Raws li cov ntsiab lus NBR nce, kev tiv thaiv rau roj av hauv paus roj thiab hydrocarbon fuels nce, tab sis tsis tshua muaj kub hloov tau txo.
Hais txog NBR
Vim nws cov khoom zoo heev rau cov khoom siv roj av, thiab nws lub peev xwm los sib xyaw ua ke rau kev pabcuam tshaj qhov kub ntawm -35 ° C txog + 120 ° C (-30 ° F txog + 250 ° F), Nitrile / NBR yog qhov dav tshaj plaws. siv elastomer hauv kev lag luam foob niaj hnub no.Tsis tas li ntawd ntau cov tub rog roj hmab specifications rau roj thiab roj resistant O-rings yuav tsum tau nitrile raws li cov tebchaw.
Nws yuav tsum tau hais tias kom tau txais kev tiv thaiv zoo rau qhov kub thiab txias, nws yog ib qho tsim nyog yuav tau txi qee qhov kub tsis kam.Nitrile tebchaw yog superior rau feem ntau elastomers hais txog compression set, tsim kua muag, thiab abrasion kuj.Nitrile compounds tsis muaj kev tiv thaiv zoo rau ozone, tshav ntuj, lossis huab cua.Lawv yuav tsum tsis txhob muab khaws cia ze ntawm lub tshuab hluav taws xob lossis lwm yam khoom siv ozone.

Khoom siv
Acrylonitrile yog ua lag luam los ntawm propylene ammoxidation, nyob rau hauv uas propylene, ammonia, thiab cua yog reacted los ntawm catalyst nyob rau hauv ib tug fluidized txaj.Acrylonitrile feem ntau yog siv los ua co-monomer hauv kev tsim cov acrylic thiab modacrylic fibers.Kev siv muaj xws li kev tsim cov yas, txheej txheej, nitrile elastomers, barrier resins, thiab cov nplaum.Nws kuj yog ib qho tshuaj nruab nrab hauv cov synthesis ntawm ntau yam antioxidants, tshuaj, dyes, thiab nto-active.
1. Acrylonitrile ua los ntawm polyacrylonitrile fiber, uas yog acrylic fiber.
2. Acrylonitrile thiab butadiene tuaj yeem ua copolymerized los tsim cov roj hmab nitrile.
3. Acrylonitrile, butadiene, styrene copolymerized los npaj ABS resin.
4. Acrylonitrile hydrolysis tuaj yeem tsim acrylamide, acrylic acid thiab nws cov esters.
