Acrylonitrile rau ABS resins
Acrylonitrile rau ABS resins,
Acrylonitrile rau Aacrylonitrile Butadiene Styrene, Acrylonitrile rauABS,
Acrylonitrile-butadiene-styrene (ABS) polymers yog tsim los ntawm elastomer dispersed raws li grafted particulate theem nyob rau hauv ib tug thermoplastic matrix ntawm styrene thiab acrylonitrile copolymer (SAN).Lub xub ntiag ntawm SAN grafted mus rau elastomeric tivthaiv, feem ntau polybutadiene los yog butadiene copolymer, compatabilizes cov roj hmab nrog cov SAN tivthaiv.Cov khoom zoo yog muab los ntawm cov graft terpolymer no muaj xws li zoo heev toughness, zoo seem stability, zoo processability, thiab tshuaj tsis kam.Qhov system yog structurally complex.Qhov no tso cai rau ntau ntau yam hauv kev txiav cov khoom kom tau raws li cov khoom lag luam tshwj xeeb.Yog li ntawd, kev tshawb fawb thiab kev loj hlob hauv ABS systems yog ua haujlwm.Ntau qib ntawm ABS muaj, suav nrog cov alloys tshiab thiab qib tshwj xeeb rau kev kub siab, nplaim taws-retardant, lossis cov khoom lag luam zoo li qub.Cov tshuaj tiv thaiv zoo ua ke nrog cov dej nqus dej tsawg

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.
