Vinyl acetate (VAC) yog ib qho tseem ceeb organic chemical raw khoom nrog cov mis molecular ntawm C4H6O2, tseem hu ua vinyl acetate thiab vinyl acetate. Vinyl acetate feem ntau yog siv los tsim cov polyvinyl cawv, ethylene-vinyl acetate copolymer (EVA resin), ethylene-vinyl cawv copolymer (EVOH resin), vinyl acetate-vinyl chloride copolymer (vinyl chloride resin), dawb latex, acrylic fiber thiab lwm yam khoom. Nws yog dav siv nyob rau hauv lub teb ntawm hluavtaws fiber, txheej, slurry, zaj duab xis, tawv ua, kev txhim kho av, thiab muaj ib tug dav zeem muag ntawm kev loj hlob thiab kev siv. Cov txheej txheem ntawm vinyl acetate muaj xws li carbide acetylene method, natural gas acetylene method and petroleum ethylene method. Txoj kev carbide acetylene feem ntau yog siv hauv Suav teb, thiab cov peev txheej ntawm carbide acetylene txoj kev yuav ncav cuag 62% hauv 2020.
Nyob rau hauv xyoo tas los no, kev lag luam xav tau ntawm vinyl acetate hauv Suav teb tau qhia tag nrho kev nce siab. Raws li kev txheeb cais ntawm Tuam Tshoj Chemical Fiber Industry Association, xyoo 2016, qhov pom tseeb ntawm kev siv vinyl acetate hauv Suav teb yog 1.94 lab tons, uas tau nce mus rau 2.33 lab tons hauv 2019. cuam tshuam los ntawm COVID-19 hauv thawj ib nrab xyoo 2020, kev khiav hauj lwm tus nqi ntawm downstream industries yog tsawg, ua rau ib tug me me poob nyob rau hauv lub pom meej noj vinyl acetate rau 2.16 lab tons; Nrog rau kev ruaj khov ntawm cov xwm txheej sib kis nyob rau hauv ib nrab ntawm lub xyoo thiab kev rov qab los ntawm kev lag luam sai, qhov kev thov rau vinyl acetate tau rov qab los sai sai txij li ib nrab xyoo 2020 txog rau thawj ib nrab xyoo 2021, tus nqi lag luam tau nce siab, thiab kev lag luam rov zoo.
Cov qauv kev thov ntawm vinyl acetate hauv Suav teb yog qhov ruaj khov, nrog polyvinyl cawv, polyvinyl acetate, VAE lotion thiab EVA resin ua cov khoom tseem ceeb. Xyoo 2020, qhov feem pua ​​​​ntawm polyvinyl cawv hauv cov qauv siv hauv tsev ntawm vinyl acetate yuav ncav cuag 65%, thiab tag nrho cov feem ntawm polyvinyl acetate, VAE lotion thiab EAV resin yuav yog 31%.
Tam sim no, Tuam Tshoj muaj peev xwm loj tshaj plaws ntawm vinyl acetate hauv ntiaj teb. Xyoo 2020, Tuam Tshoj lub peev xwm ntawm vinyl acetate yuav ncav cuag 2.65 lab tons, suav txog li 40% ntawm lub ntiaj teb tag nrho lub peev xwm. Nyob rau hauv xyoo tas los no, lub peev xwm rov qab nyob rau hauv Tuam Tshoj txoj kev lag luam yas acetate tau maj mam thim rov qab, thiab muaj peev xwm siab ntxiv tau ntxiv los ua lag luam sib txawv. Nrog rau kev txhim kho tas mus li ntawm kev lag luam cov qauv, Tuam Tshoj cov yas acetate ntau lawm tau qhia txog kev loj hlob tag nrho. Raws li kev txheeb cais ntawm Tuam Tshoj Chemical Fiber Industry Association, cov khoom siv hauv tsev vinyl acetate tau nce los ntawm 1.91 lab tons hauv 2016 txog 2.28 lab tons hauv 2019, nrog rau kev loj hlob txhua xyoo ntawm 5.98%; Xyoo 2020, vim tias cov nqi roj thoob ntiaj teb qis, cov nqi tsim khoom ntawm cov roj av ethylene txawv teb chaws raug txo, kev xa khoom ntawm vinyl acetate hauv Suav teb tau nce, thiab cov khoom siv hauv tsev ntawm vinyl acetate poob mus rau 1.99 lab tons; Txij li thaum lub thib ob ib nrab ntawm 2020, nrog rau lub ntiaj teb no kev lag luam rov qab thiab nce ntawm cov nqi roj thoob ntiaj teb, kev tsim khoom ntawm domestic vinyl acetate kev lag luam tau sov so.
