Ndi mafakitale ati omwe amagwiritsidwa ntchito kwambiri ndi acrylonitrile?

Acrylonitrile imapangidwa ndi propylene ndi ammonia ngati zida zopangira makutidwe ndi okosijeni komanso njira yoyenga.Ndi mtundu wa organic pawiri, mankhwala chilinganizo ndi C3H3N, ndi colorless madzi ndi fungo lamphamvu, kuyaka, nthunzi yake ndi mpweya akhoza kupanga kuphulika osakaniza, ngati moto lotseguka, kutentha kwambiri n'zosavuta kuyambitsa kuyaka, ndi kumasula mpweya wapoizoni. , ndi okosijeni, asidi amphamvu, maziko amphamvu, amines, bromine reaction.

Amagwiritsidwa ntchito makamaka ngati zopangira za acrylic fiber ndi ABS/SAN resin.Komanso, chimagwiritsidwa ntchito kupanga acrylamide, phala ndi adiponitrile, kupanga mphira, Latex, etc.

Mapulogalamu amsika a Acrylonitrile

Acrylonitrile ndi zofunika zopangira zinthu zitatu zopangira (pulasitiki, mphira wopangira, fiber).Kutsika kwa mtsinje wa acrylonitrile kumayikidwa m'madera atatu a ABS, acrylic ndi acrylamide, omwe amawerengera oposa 80% a mowa wonse wa acrylonitrile.M'zaka zaposachedwa, ndi chitukuko cha zida zapanyumba ndi mafakitale amagalimoto, China yakhala imodzi mwamisika yomwe ikukula mwachangu kwambiri padziko lonse lapansi ya acrylonitrile.Zogulitsa zapansi panthaka zimagwiritsidwa ntchito kwambiri pazida zapakhomo, zovala, magalimoto, mankhwala ndi madera ena azachuma cha dziko.

Acrylonitrile imapangidwa ndi makutidwe ndi okosijeni komanso kuyenga kwa propylene ndi madzi ammonia.Amagwiritsidwa ntchito kwambiri popanga utomoni ndi mafakitale a acrylic fiber.Carbon fiber ndiye gawo logwiritsira ntchito lomwe likukula mwachangu mtsogolo.

Monga imodzi mwazinthu zofunika kwambiri kumunsi kwa acrylonitrile, kaboni fiber ndi chinthu chatsopano chomwe chimafufuzidwa ndikupangidwa ku China.Mpweya wa kaboni wakhala chinthu chofunikira kwambiri pazida zopepuka, ndipo pang'onopang'ono kuchokera ku zida zam'mbuyomu zachitsulo, zakhala zofunikira kwambiri pantchito zankhondo ndi zankhondo.

Chifukwa chakukula kwachuma kwadziko lathu, kufunikira kwa kaboni fiber ndi zinthu zake zambiri kukukulirakulira.Malinga ndi ziwerengero zoyenera, kufunikira kwa China kwa carbon fiber kudafika matani 48,800 mu 2020, kuwonjezeka kwa 29% poyerekeza ndi 2019.

Ndikukula kosalekeza kwa sayansi ndi ukadaulo, msika wa acrylonitrile ukuwonetsa chitukuko chachikulu:

Mmodzi ndi propane monga zopangira acrylonitrile kupanga mzere kukwezedwa pang'onopang'ono;

Chachiwiri, kafukufuku wa zolimbikitsa zatsopano akadali mutu wofufuza wa akatswiri apakhomo ndi akunja;

Chachitatu, chipangizo chachikulu;

Chachinayi, kupulumutsa mphamvu ndi kuchepetsa umuna, kukhathamiritsa kwa ndondomeko ndikofunika kwambiri;

Chachisanu, chithandizo chamadzi onyansa chakhala chofunikira kwambiri pa kafukufuku.
