Acrylonitrile rau Acrylic fiber
Acrylonitrile rau Acrylic fiber,
Acrylonitrile siv hauv kev tsim cov Modacrylic Fibers,
Acrylic fiber ntau yog cov hluavtaws fiber ntau zoo ib yam li cov ntaub plaub.Acrylic fibers yog tsim los ntawm spinning acrylonitrile copolymer uas muaj tsawg kawg yog 85% acrylonitrile monomer.Txhawm rau tsim cov filaments txuas ntxiv, cov polymer yog yaj hauv qhov hnyav thiab extruded los ntawm spinnerets.Tom qab ntawd, cov filaments tsis tu ncua yog ntxuav thiab qhuav.

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.
