Thaum lub Cuaj Hlis 2023, isopropanol kev ua lag luam tau qhia txog tus nqi nce siab, nrog cov nqi txuas ntxiv mus txog qhov siab tshiab, ntxiv dag zog rau kev lag luam. Kab lus no yuav txheeb xyuas qhov kev txhim kho tshiab hauv kev ua lag luam no, suav nrog cov laj thawj ntawm tus nqi nce, tus nqi ntawm cov khoom siv, cov khoom siv thiab kev xav tau, thiab kev kwv yees yav tom ntej.

Sau tus nqi siab

Raws li lub Cuaj Hlis 13, 2023, tus nqi lag luam nruab nrab ntawm isopropanol hauv Suav teb tau mus txog 9000 yuan ib tuj, nce 300 yuan lossis 3.45% piv rau hnub ua haujlwm dhau los. Qhov no tau coj tus nqi ntawm isopropanol nyob ze rau nws qib siab tshaj plaws nyob rau hauv ze li peb xyoos thiab tau txais kev saib xyuas thoob plaws.

Tus nqi tseem ceeb

Tus nqi sab yog ib qho tseem ceeb uas ua rau tus nqi ntawm isopropanol. Acetone, raws li cov khoom siv tseem ceeb rau isopropanol, kuj tau pom qhov nce ntxiv ntawm nws cov nqi. Tam sim no, tus nqi lag luam nruab nrab ntawm acetone yog 7585 yuan ib tuj, nce 2.62% piv rau hnub ua haujlwm dhau los. Kev xa khoom ntawm acetone hauv kev ua lag luam yog nruj, nrog rau feem ntau cov neeg muag khoom muag thiab cov chaw tsim khoom tau kaw ntau dua, ua rau muaj qhov tsis txaus ntawm cov khw muag khoom. Tsis tas li ntawd, kev lag luam tus nqi ntawm propylene kuj tseem nce ntxiv, nrog tus nqi nruab nrab ntawm 7050 yuan ib tuj, nce 1.44% piv rau hnub ua haujlwm dhau los. Qhov no muaj feem xyuam nrog kev nce hauv cov nqi roj av thoob ntiaj teb thiab qhov tseem ceeb ntawm cov khoom lag luam hauv qab polypropylene yav tom ntej thiab cov nqi hmoov hmoov, uas tau ua rau kev ua lag luam kom muaj tus cwj pwm zoo rau cov nqi propylene. Zuag qhia tag nrho, qhov kev sib tw siab ntawm tus nqi sab nraud tau muab kev txhawb nqa tseem ceeb rau tus nqi ntawm isopropanol, ua rau cov nqi nce.

Nyob rau sab khoom

Ntawm qhov chaw muab khoom, tus nqi khiav haujlwm ntawm isopropanol cog tau nce me ntsis rau lub lim tiam no, xav tias yuav nyob ib puag ncig 48%. Txawm hais tias qee lub tuam txhab cov khoom siv tau rov pib dua, qee qhov isopropanol units hauv Shandong cheeb tsam tseem tsis tau rov pib dua li qub kev thauj khoom. Txawm li cas los xij, kev xa tawm hauv nruab nrab ntawm kev xa khoom xa tawm tau ua rau muaj qhov tsis txaus ntawm qhov chaw muab khoom, ua rau kev lag luam cov khoom muag qis. Cov neeg tuav tswj hwm tus cwj pwm ceev faj vim muaj cov khoom muag tsawg, uas rau qee qhov txhawb tus nqi nce.

Supply thiab xav tau qhov xwm txheej

Nyob rau hauv cov nqe lus ntawm kev thov, downstream terminals thiab cov tub lag luam tau maj mam nce lawv cov khoom xav tau nyob rau hauv nruab nrab thiab lig theem, uas tau tsim kev txhawb nqa zoo rau cov nqi lag luam. Tsis tas li ntawd, kev thov xa tawm kuj tau nce ntxiv, ntxiv rau kev tsav tsheb nce nqi. Zuag qhia tag nrho, cov khoom muag thiab kev thov sab tau pom qhov zoo sib xws, nrog ntau lub khw muag khoom muaj kev tsis txaus, nce kev thov rau cov khoom kawg, thiab txuas ntxiv cov xov xwm zoo.

Kev kwv yees yav tom ntej

Txawm hais tias cov khoom siv raw khoom siab thiab ruaj khov, cov khoom siv sab nraud tseem txwv, thiab qhov kev thov sab qhia pom qhov zoo, nrog rau ntau yam zoo txhawb kev nce hauv isopropanol tus nqi. Nws cia siab tias tseem muaj chaw rau kev txhim kho hauv kev lag luam hauv tsev isopropanol lub lim tiam tom ntej, thiab tus nqi tseem ceeb yuav hloov pauv ntawm 9000-9400 yuan / tuj.

Cov ntsiab lus

Thaum lub Cuaj Hlis 2023, tus nqi lag luam ntawm isopropanol tau mus txog qhov siab tshiab, tau tsav los ntawm kev sib cuam tshuam ntawm tus nqi sab thiab cov khoom siv sab nraud. Txawm hais tias kev ua lag luam yuav muaj kev hloov pauv, qhov kev sib tw mus sij hawm ntev tseem nce siab. Kev ua lag luam yuav ua tib zoo saib xyuas cov nqi thiab cov khoom siv thiab cov kev xav tau kom nkag siab ntxiv txog kev loj hlob ntawm kev ua lag luam.
