Txij li xyoo 2020, cov nroj tsuag polyethylene hauv tsev tau nkag mus rau hauv lub voj voog nthuav dav, thiab lub peev xwm tsim khoom txhua xyoo ntawm PE hauv tsev tau nce sai, nrog rau qhov nruab nrab txhua xyoo kev loj hlob ntawm ntau dua 10%. Kev tsim cov polyethylene tsim hauv tsev tau nce sai, nrog rau cov khoom lag luam sib xyaw ua ke thiab kev sib tw hnyav hauv kev lag luam polyethylene. Txawm hais tias qhov kev thov rau polyethylene kuj tau qhia txog kev loj hlob hauv xyoo tas los no, qhov kev thov loj hlob tsis tau nrawm npaum li qhov kev loj hlob ntawm kev muab khoom. Txij li xyoo 2017 txog 2020, lub peev xwm tsim khoom tshiab ntawm polyethylene hauv tsev feem ntau tsom mus rau cov hluav taws xob qis thiab cov kab ncaj, thiab tsis muaj cov khoom siv hluav taws xob siab tau muab tso rau hauv kev ua haujlwm hauv Suav teb, ua rau muaj kev ua tau zoo hauv kev lag luam hluav taws xob siab. Xyoo 2020, raws li qhov sib txawv ntawm tus nqi ntawm LDPE thiab LLDPE maj mam nthuav dav, kev saib xyuas ntawm cov khoom LDPE tau nce ntxiv. Chav tsev tsim khoom EVA thiab chav tsev Zhejiang Petrochemical LDPE tau muab tso rau hauv kev ua haujlwm hauv xyoo 2022, nrog rau lub peev xwm tsim khoom siab hauv tsev ntawm 3.335 lab tons txij li hnub dhau los.
Xyoo 2023, kev ua lag luam siab tau qhia txog kev hloov pauv thiab poob qis. Piv txwv li, kev ua lag luam sab qaum teb Tuam Tshoj, tus nqi nruab nrab ntawm lub Ib Hlis mus txog rau lub Tsib Hlis yog 8853 yuan / ton, qhov poob qis tseem ceeb ntawm 24.24% xyoo-rau-xyoo. Thaum lub caij siab tshaj plaws ntawm kev thov yas zaj duab xis hauv peb lub hlis thawj zaug, tus nqi linear tau muaj zog heev. Tus nqi nruab nrab ntawm lub Ib Hlis mus txog rau lub Plaub Hlis yog 8273, qhov poob qis ntawm 7.42% xyoo-rau-xyoo. Qhov sib txawv ntawm tus nqi hluav taws xob siab thiab linear tau nqaim heev. Txij li thaum Lub Tsib Hlis 23, cov khoom siv hauv tsev hauv kev ua lag luam sab qaum teb Tuam Tshoj yog 7700-7950 yuan / ton, thaum cov yeeb yaj kiab hauv tsev hauv tsev siab tau tshaj tawm ntawm 8000-8200 yuan / ton. Qhov sib txawv ntawm tus nqi hluav taws xob siab thiab linear yog 250-300 yuan / ton.
Zuag qhia tag nrho, nrog rau kev nthuav dav ntawm cov peev xwm tsim khoom polyethylene hauv tsev thiab kev nce qib maj mam ntawm kev muab khoom hauv tsev, qhov teeb meem ntawm kev muab khoom ntau dhau hauv kev lag luam polyethylene tau nce ntxiv. Txawm hais tias tus nqi tsim khoom rau qhov hluav taws xob siab me ntsis siab dua li linear, vim yog qhov hloov pauv ntawm linear thiab metallocene hauv qee qhov chaw tsim khoom, nws nyuaj rau txhawb nqa tus nqi siab thiab cov txiaj ntsig siab hauv kev lag luam polyethylene tsis muaj zog tam sim no, thiab qhov sib txawv ntawm tus nqi ntawm qhov hluav taws xob siab thiab linear tau nqaim heev.
