[Introduction] : Pib txij xyoo 2020, Tuam Tshoj cov polyethylene tau nkag mus rau qhov tshiab ntawm kev nthuav dav hauv nruab nrab, thiab nws cov peev txheej tsim tau txuas ntxiv, nrog rau 2.6 lab tons ntawm cov peev txheej tshiab hauv xyoo 2023, thiab tag nrho ntawm 32.41 lab tons ntawm polyethylene muaj peev xwm ntau lawm. , nce 8.72% piv nrog 2022; Xyoo 2023, Tuam Tshoj cov khoom siv polyethylene yuav tsum yog 28.1423 lab tons, nce 11.16% tshaj 2022.

Los ntawm 2019 txog 2023, Tuam Tshoj tus polyethylene tsim muaj peev xwm nce tsis tu ncua, nrog kev loj hlob ntawm 13.31%. Txij li xyoo 2020, nrog kev nce ntawm cov lag luam hauv zos, polyethylene tau nkag mus rau lub sijhawm tshiab ntawm kev nthuav dav hauv nruab nrab, sawv cev ntawm cov tuam txhab Wanhua Chemical, Zhejiang Petrochemical thiab Lianyungang Petrochemical, polyethylene raw cov ntaub ntawv muaj ntau haiv neeg, thiab lub suab ntawm cov lag luam hauv zos tau txhim kho tas li. .

Tom qab xyoo 2020, Tuam Tshoj tau nkag mus rau lub sijhawm ntawm kev ua kom zoo thiab tshuaj lom neeg muaj peev xwm nthuav dav, nrog rau kev nce qib ntawm kev ua kom zoo thiab tshuaj lom neeg kev koom ua ke thiab kev ua kom zoo dua qub thiab txhim kho cov qauv kev lag luam, kev lag luam cuam tshuam kuj tseem muaj zog, thiab kev vam khom ntawm polyethylene ntshuam kuj tseem muaj. maj mam poob qis, thiab kev vam khom ntawm polyethylene ntshuam yuav tsum poob mus txog 32% hauv 2023. Los ntawm qhov kev xav ntawm tag nrho cov khoom tsim ntawm kev lag luam hauv tsev, txawm hais tias feem ntau ntawm cov khoom siv tshwj xeeb tau nce, feem ntau ntawm cov ntaub ntawv tseem yog ib yam nkaus. loj, homogenization yog loj, thiab kev sib tw ntawm cov lag luam yog nce intensified.

Nyob rau hauv 2023, tag nrho ntawm 2.6 lab tons ntawm polyethylene muaj peev xwm yuav ntxiv, nrog HDPE thiab tag nrho-density installations tseem yog lub ntsiab sawv daws yuav, uas HDPE ntau lawm muaj peev xwm yuav nce 1.9 lab tons thiab LLDPE ntau lawm muaj peev xwm yuav nce 700,000 tons. . Los ntawm cheeb tsam, cov tuam txhab muab tso rau hauv kev tsim khoom feem ntau yog nyob rau sab qab teb Tuam Tshoj, South Tuam Tshoj txoj kev tsim khoom tshiab muaj peev xwm tag nrho 1.8 lab tons, suav txog 69.23% ntawm txhua xyoo nce, thiab cov khoom siv siab hauv South Tuam Tshoj tau nce. Nyob rau hauv 2023, Tuam Tshoj tus polyethylene muaj peev xwm muaj tag nrho 32.41 lab tons, nce 8.72% piv nrog 2022. Ntawm lawv, HDPE muaj peev xwm ntawm 15.115 lab tons, LDPE muaj peev xwm ntawm 4.635 lab tons (suav nrog 1.3 lab tons ntawm LDPE / EVA. co-production units), thiab LLDPE muaj peev xwm ntawm 12.66 lab tons.

Tuam Tshoj txoj kev lag luam polyethylene muaj peev xwm txuas ntxiv nthuav dav, tau tsav los ntawm kev nce hauv kev tsim khoom ib xyoos ib zaug, 2023 polyethylene tshiab muaj peev xwm ntawm 2.6 lab tons, superposition roj crude nqi poob los ntawm xyoo tas los siab, kev lag luam muaj peev xwm siv tau raug kho, ntau lawm tsis tu ncua. Raws li kev txheeb cais los ntawm Longzhong Cov Ntaub Ntawv, qhov sib xyaw ua ke ntawm polyethylene ntau lawm hauv Suav teb los ntawm 2019 txog 2023 yuav tsum yog 12.39%, thiab cov khoom tsim tawm txhua xyoo ntawm polyethylene hauv Suav teb xyoo 2023 yuav tsum yog 28.1423 lab tons, nce ntawm 11.16%. piv nrog 2022.

Nyob rau hauv 2023, Tuam Tshoj tus HDPE polyethylene ntau lawm accounted rau 46.50% ntawm tag nrho cov zis, LLDPE polyethylene ntau lawm accounted rau 42.22% ntawm tag nrho cov zis, LDPE polyethylene ntau lawm accounted rau 11.28% ntawm tag nrho cov zis, thiab cov cuab yeej muab tso rau hauv lub lag luam nyob rau hauv 2023. Yeej los ntawm HDPE thiab cov khoom siv hluav taws xob puv nthab, thiab cov txiaj ntsig piv ntawm HDPE tau nce. Qhov kev faib ua feem ntawm LDPE thiab LLDPE ntau lawm poob me ntsis.
