Acrylonitrile rau NBR
Acrylonitrile rau NBR,
Acrylonitrile Rau Nitrile Roj Hmab,
Nitrile (feem ntau hu ua buna-N roj hmab lossis perbunan) yog feem ntau siv elastomer hauv kev lag luam foob.Nitrile yog ib copolymer ntawm ob monomers: acrylonitrile (ACN) thiab butadiene.Cov khoom ntawm cov roj hmab sib txuas yog txiav txim siab los ntawm nws cov ntsiab lus ACN, uas tau muab faib ua peb pawg:
High nitrile> 45% ACN cov ntsiab lus,
Nruab nrab nitrile 30-45% ACN cov ntsiab lus,
Tsawg nitrile <30% ACN cov ntsiab lus.
Qhov siab dua ntawm ACN cov ntsiab lus, qhov zoo dua nws tiv thaiv cov roj hydrocarbon.Qhov qis dua cov ntsiab lus ACN qhov zoo dua nws qhov yooj yim hauv cov ntawv thov kub tsawg.Medium nitrile yog, yog li ntawd, feem ntau tau teev tseg vim nws qhov zoo tag nrho qhov sib npaug hauv feem ntau daim ntawv thov.Feem ntau, nitriles tuaj yeem sib xyaw ua haujlwm tshaj qhov kub ntawm -35 ° C txog + 120 ° C thiab zoo tshaj rau feem ntau cov elastomers hais txog compression teeb, tsim kua muag thiab puas.

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.
