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 mankhwala organic, chilinganizo mankhwala C3H3N, ndi colorless pungent madzi, kuyaka, nthunzi ndi mpweya akhoza kupanga kuphulika osakaniza, pa nkhani ya moto lotseguka, kutentha kwambiri n'kosavuta kuyambitsa kuyaka, ndi kumasula mpweya wapoizoni, ndi oxidant, asidi amphamvu, maziko amphamvu, amine, bromine reaction mwankhanza.

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

Azovuta

Acrylonitrile ndi zinthu zitatu zazikulu zopangira (pulasitiki, mphira wopangira, mphira wopangira) zofunika zopangira, dziko lathu la acrylonitrile kunsi kwamtsinje limakhala mu ABS, acrylic ndi acrylamide minda itatu, nkhani zitatu za 80% yakugwiritsa ntchito okwana 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.

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

1. propane monga zopangira za acrylonitrile kupanga mzere pang'onopang'ono kulimbikitsa;
2. kafukufuku wa zoyambitsa zatsopano akadali mutu wofufuza wa akatswiri kunyumba ndi kunja;
3. chipangizo chachikulu;
4. kuteteza mphamvu ndi kuchepetsa umuna, ndondomeko kukhathamiritsa ndi zofunika kwambiri;
5. Kuchiza kwa madzi onyansa kwakhala chinthu chofunika kwambiri pa kafukufuku.
