Txawm tiasphenol thiab ketone yog cov khoom sib koom ua ke, cov lus qhia noj phenol thiab acetone sib txawv heev. Acetone yog dav siv los ua tshuaj nruab nrab thiab hnyav. Cov dej ntws loj heev yog isopropanol, MMA thiab bisphenol A.
Nws tau tshaj tawm tias kev lag luam acetone thoob ntiaj teb yog nyob rau hauv qhov xwm txheej ntawm kev xa khoom ntau dhau. Suav lag luam yog qhov chaw tseem ceeb tshaj plaws rau kev ncig ntawm cov khoom thoob ntiaj teb. Tam sim no, Tuam Tshoj tseem muaj cov khoom lag luam loj ntawm acetone, thiab cov khoom siv hauv tsev kuj tseem nce ntxiv.
Txawm li cas los xij, ntawm qhov xav tau, tshwj tsis yog rau kev txhim kho ntawm bisphenol A, qhov kev loj hlob ntawm lwm cov kev lag luam hauv qab loj yog qeeb, ua rau qhov kev xav tau qeeb qeeb ntawm acetone tshaj qhov kev loj hlob ntawm cov khoom siv, thiab qhov kev thov qeeb qeeb dua li qhov nruab nrab ntawm theem tsis ntev los no. tsib xyoos, uas tsis haum rau tus nqi nce.
Hauv xyoo 2022, nrog kev txhim kho ntawm acetone hauv qab dej, qhov kev faib ua feem ntawm cov dej ntws tau hloov pauv ntau, thiab bisphenol A thiab MMA yog qhov tseem ceeb tshaj plaws hauv qab acetone. Lub peev xwm ntawm MMA yuav nce 47% hauv 2022, thiab qhov nruab nrab txhua xyoo kev loj hlob yuav yog 25% hauv 2018-2022. Hauv qee lub sijhawm, qhov kev thov rau acetone kuj muaj lub luag haujlwm txhawb nqa.
Lub peev xwm tsim tawm ntawm isopropanol nyob rau hauv thawj downstream tau poob qis, thiab kev noj cov isopropanol yuav qhia qhov kev loj hlob tsis zoo nyob rau hauv 2022, nrog rau qhov nruab nrab txhua xyoo kev loj hlob ntawm 5% hauv 2018-2022. Txawm li cas los xij, isopropanol export lag luam yog qhov zoo. Nyob rau hauv 2022, lub export ntim yuav nce los ntawm 62%, tsav lub domestic output kom loj hlob los ntawm 9%, thiab ua kom muaj kev loj hlob siab tshaj plaws nyob rau hauv lub lag luam saw nrog ib tug tag nrho cov nyiaj tau los ntawm 188%.

Kev loj hlob ntawm acetone xav tau qeeb, thiab tus nqi siab yuav tsum muaj

Hauv xyoo 2022, nrog kev txhim kho ntawm acetone hauv qab dej, qhov kev faib ua feem ntawm cov dej ntws tau hloov pauv ntau, thiab bisphenol A thiab MMA yog qhov tseem ceeb tshaj plaws hauv qab acetone. Lub peev xwm ntawm MMA yuav nce 47% hauv 2022, thiab qhov nruab nrab txhua xyoo kev loj hlob yuav yog 25% hauv 2018-2022.

Lub peev xwm tsim tawm ntawm isopropanol nyob rau hauv thawj downstream tau poob qis, thiab kev noj cov isopropanol yuav qhia qhov kev loj hlob tsis zoo nyob rau hauv 2022, nrog rau qhov nruab nrab txhua xyoo kev loj hlob ntawm 5% hauv 2018-2022.
