Acrylonitrile: Ndi mafakitale ati omwe amagwiritsidwa ntchito kwambiri? Tsogolo la acrylonitrile ndi lotani?

Acrylonitrile amapangidwa ndi oxidation reaction ndi njira yoyenga pogwiritsa ntchito propylene ndi ammonia madzi ngati zopangira.Ndi mtundu wa organic mankhwala, chilinganizo mankhwala C3H3N, ndi colorless pungent madzi, kuyaka, nthunzi ndi mpweya akhoza kupanga kuphulika osakaniza, pa nkhani ya moto lotseguka, kutentha n'zosavuta chifukwa kuyaka, ndi kumasula mpweya wakupha, ndi oxidant. , asidi amphamvu, maziko amphamvu, amine, bromine amachita mwachiwawa.

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

Acrylonitrilentchito zamsika

Acrylonitrile ndi zinthu zitatu zazikulu zopangira (pulasitiki, mphira wopangira, ulusi wopangira) zofunika zopangira,dziko lathu acrylonitrile kutsika kwa madzi akugwiritsidwa ntchito mu ABS, acrylic ndi acrylamide minda atatu, atatu nkhani pafupifupi 80% ya okwana kumwa acrylonitrile. M'zaka zaposachedwa, ndi chitukuko cha zida zapakhomo ndi magalimoto, China yakhala imodzi mwamayiko omwe akukula mwachangu pamsika wapadziko lonse wa acrylonitrile. Zogulitsa zapansi panthaka zimagwiritsidwa ntchito kwambiri pazida zam'nyumba, zovala, magalimoto, mankhwala ndi zina pazachuma cha dziko.

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

Mpweya wa carbon, monga imodzi mwazinthu zofunika kwambiri zomwe zimagwiritsidwa ntchito kumunsi kwa acrylonitrile, ndi chinthu chatsopano chomwe chimayang'ana pa kafukufuku ndi chitukuko ku China.Mpweya wa kaboni wakhala chinthu chofunikira kwambiri pazida zopepuka, ndipo pang'onopang'ono kuchokera ku zida zam'mbuyomu zachitsulo, m'mabwalo ankhondo ndi zankhondo zakhala zofunikira kwambiri.

Ndi chitukuko chosalekeza cha sayansi ndi ukadaulo,acrylonitrilemsika uli ndi chitukuko chachikulu:

Choyamba, propane monga zopangira za mzere wopanga acrylonitrile zimalimbikitsidwa pang'onopang'ono;
Chachiwiri, kafukufuku wa zoyambitsa zatsopano akadali mutu wofufuza wa akatswiri kunyumba ndi kunja;
Chachitatu, chipangizo chachikulu;
Chachinayi, kuteteza mphamvu ndi kuchepetsa umuna, kukhathamiritsa kwa ndondomeko ndikofunika kwambiri;
Chachisanu, chithandizo chamadzi onyansa chakhala chofunikira kwambiri pa kafukufuku.

Chitukuko chamtsogolo cha acrylonitrile
Malinga ndi zonenedweratu, acrylonitrile zaka 5 zikubwerazi dziko lathu kupanga mphamvu kukula ndi yaikulu kuposa kutsika kufunikira kukula, voliyumu yochokera kunja adzatsika, kunja kupitiriza kuwonjezeka, kuti kuchepetsa kupanikizika kwa ntchito msika wapakhomo.
