Acrylonitrile yog ua los ntawm propylene thiab ammonia ua raw khoom los ntawm oxidation cov tshuaj tiv thaiv thiab refining txheej txheem.Yog ib hom organic compound, chemical formula yog C3H3N, yog cov kua xim tsis muaj xim nrog pungent tsw, flammable, nws vapor thiab huab cua tuaj yeem tsim kev sib xyaw tawg, thaum qhib hluav taws, kub kub yog ib qho yooj yim ua rau combustion, thiab tso tawm cov pa phem. , thiab oxidants, muaj zog acids, muaj zog bases, amines, bromine cov tshuaj tiv thaiv.
Nws yog tsuas yog siv los ua raw khoom rau acrylic fiber thiab ABS / SAN resin.Tsis tas li ntawd, nws yog dav siv nyob rau hauv zus tau tej cov acrylamide, muab tshuaj txhuam thiab adiponitrile, hluavtaws roj hmab, Latex, thiab lwm yam.
Kev lag luam Acrylonitrile
Acrylonitrile yog ib qho tseem ceeb raw khoom ntawm peb cov khoom siv hluavtaws (yas, hluavtaws roj hmab, hluavtaws fiber ntau).Kev noj qab haus huv ntawm acrylonitrile yog concentrated nyob rau hauv peb qhov chaw ntawm ABS, acrylic thiab acrylamide, uas suav txog ntau dua 80% ntawm tag nrho cov kev siv acrylonitrile.Nyob rau hauv xyoo tas los no, nrog rau kev txhim kho cov khoom siv hauv tsev thiab kev lag luam tsheb, Tuam Tshoj tau dhau los ua ib qho ntawm lub ntiaj teb kev lag luam acrylonitrile loj tshaj plaws.Cov khoom siv hauv qab no tau siv dav hauv cov khoom siv hauv tsev, khaub ncaws, tsheb, tshuaj thiab lwm yam kev lag luam hauv lub tebchaws.
Acrylonitrile yog tsim los ntawm oxidation cov tshuaj tiv thaiv thiab refining txheej txheem ntawm propylene thiab ammonia dej.Nws yog dav siv nyob rau hauv zus tau tej cov resin thiab acrylic fiber kev lag luam.Carbon fiber yog daim ntawv thov teb nrog kev loj hlob sai ntawm kev thov yav tom ntej.
Raws li ib qho ntawm cov kev siv tseem ceeb ntawm acrylonitrile, carbon fiber yog cov khoom siv tshiab uas tau tshawb fawb thiab tsim hauv Suav teb.Cov pa roj carbon fiber tau dhau los ua ib feem tseem ceeb ntawm cov khoom siv hnyav, thiab maj mam los ntawm cov ntaub ntawv hlau yav dhau los, tau dhau los ua cov khoom siv tseem ceeb hauv kev ua tub rog thiab tub rog.
Nrog kev txhim kho kev lag luam nrawm nrawm ntawm peb lub teb chaws, qhov kev thov rau carbon fiber ntau thiab nws cov khoom sib xyaw tau nce zuj zus.Raws li kev txheeb cais, Tuam Tshoj qhov kev thov rau carbon fiber tau mus txog 48,800 tons hauv 2020, nce 29% piv nrog 2019.
Nrog kev txhim kho txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis, kev lag luam acrylonitrile qhia tau hais tias muaj kev txhim kho zoo:
Ib qho yog propane li raw khoom acrylonitrile ntau lawm kab nyob rau hauv gradual nce qib;
Qhov thib ob, kev tshawb fawb ntawm cov catalysts tshiab tseem yog cov ncauj lus tshawb fawb ntawm cov kws tshawb fawb hauv tsev thiab txawv teb chaws;
Thib peb, cov cuab yeej loj loj;
Plaub, kev txuag hluav taws xob thiab txo qis emissions, kev ua kom zoo dua yog qhov tseem ceeb ntxiv;
Thib tsib, kev kho dej khib nyiab tau dhau los ua cov ntsiab lus tshawb fawb tseem ceeb.
