Kev siv
Ib qho ntawm cov kev siv tseem ceeb ntawm acrylonitrile yog kev tsim cov polyacrylonitrile, ntau yam polymer nrog thermal stability thiab tshuaj lom neeg. Cov polymer no tau siv dav hauv kev lag luam textile los tsim cov khaub ncaws ua haujlwm siab thiab cov ntaub uas tuaj yeem tiv taus ib puag ncig hnyav. Tsis tas li ntawd, acrylonitrile yog ib qho tseem ceeb hauv tsev thaiv hauv kev tsim cov roj hmab nitrile, uas paub txog nws cov roj zoo heev thiab tshuaj lom neeg. Qhov no ua rau nws yog qhov kev xaiv nrov rau kev tsim cov hnab looj tes, cov ntsaws ruaj ruaj thiab gaskets siv hauv tsheb, kev kho mob thiab roj av kev lag luam.
Acrylonitrile tseem ua lub luag haujlwm tseem ceeb hauv kev tsim cov dyes thiab cov khoom siv hluavtaws. Nws cov qauv tshuaj tuaj yeem siv los tsim cov xim zoo nkauj thiab ntev ntev rau kev siv xws li textiles mus rau luam ntawv inks. Tsis tas li ntawd, nws siv rau hauv cov khoom siv hluavtaws ua rau kev txhim kho cov khoom siv ruaj khov thiab lub teeb yuag rau kev tsim kho, rooj tog zaum thiab automotive industries. Cov khoom zoo no ua rau acrylonitrile yog ib qho tseem ceeb rau kev ua cov khoom uas yuav tsum tau muaj zog thiab zoo nkauj.
Ntxiv rau nws cov ntawv thov hauv kev tsim khoom, acrylonitrile kuj tseem siv hauv kev lag luam kws tshuaj. Nws yog lub tsev thaiv rau ntau yam tshuaj, suav nrog tshuaj tua kab mob, tshuaj tiv thaiv kab mob thiab tshuaj qog noj ntshav. Nws lub peev xwm los teb nrog lwm cov tebchaw tso cai rau kev sib txuas ntawm cov molecules complex nrog cov khoom kho mob. Qhov no qhia txog qhov tseem ceeb ntawm acrylonitrile hauv kev kho mob, pab txhim kho cov tshuaj cawm txoj sia.
Hauv kev xaus, acrylonitrile yog ib qho khoom tseem ceeb uas tau hloov pauv ntau yam kev lag luam. Txawm hais tias nws cov nplaim taws thiab muaj peev xwm ua rau muaj kev phom sij, nws siv hauv kev tsim cov polyacrylonitrile, nitrile roj hmab, dyes, hluavtaws resins, thiab kws tshuaj ua rau nws yog ib qho tseem ceeb ntawm kev tsim khoom niaj hnub. Txawm hais tias ua cov ntaub ntawv muaj txiaj ntsig zoo, cov khoom siv hluav taws xob ruaj khov lossis cov tshuaj cawm txoj sia, acrylonitrile ua lub luag haujlwm tseem ceeb hauv kev tsim lub ntiaj teb peb nyob niaj hnub no.
