Kev lag luam isopropanol poob rau lub lim tiam no. Hnub Thursday kawg, tus nqi nruab nrab ntawm isopropanol hauv Suav teb yog 7140 yuan / tuj, hnub Thursday tus nqi nruab nrab yog 6890 yuan / ton, thiab tus nqi nruab nrab txhua lub lim tiam yog 3.5%.

Lub lim tiam no, kev lag luam hauv tsev isopropanol tau poob qis, uas tau nyiam kev lag luam. Kev ua lag luam lub teeb ci tau nce ntxiv, thiab kev ua kom pom tseeb ntawm kev lag luam isopropanol hauv tsev tau poob qis. Qhov kev poob qis no feem ntau cuam tshuam los ntawm kev txo qis hauv cov nqi hluav taws xob acetone thiab acrylic acid, uas ua rau tsis muaj nqi txhawb rau isopropanol. Meanwhile, downstream procurement enthusiasm yog qhov tsawg, feem ntau lees txais kev txiav txim ntawm kev thov, ua rau cov khoom lag luam qis tag nrho. Cov neeg ua haujlwm feem ntau tau txais kev tos-thiab-pom tus cwj pwm, nrog txo kev thov rau kev nug thiab kev qeeb hauv kev xa khoom ceev.
Raws li cov ntaub ntawv ua lag luam, tam sim no, cov lus hais rau isopropanol hauv cheeb tsam Shandong yog kwv yees li 6600-6900 yuan / tuj, thaum cov lus hais rau isopropanol hauv cheeb tsam Jiangsu thiab Zhejiang yog li 6900-7400 yuan / ton. Qhov no qhia tau hais tias tus nqi lag luam tau poob qis rau qee qhov, thiab cov khoom siv thiab kev xav tau kev sib raug zoo kuj tsis muaj zog.

Hais txog acetone nyoos, kev lag luam acetone kuj tau poob rau lub lim tiam no. Cov ntaub ntawv qhia tau hais tias tus nqi nruab nrab ntawm acetone hnub Thursday kawg yog 6420 yuan / tuj, thaum hnub Thursday tus nqi nruab nrab yog 5987.5 yuan / ton, txo qis ntawm 6.74% piv rau lub lim tiam dhau los. Lub Hoobkas txo nqi ntsuas ntawm kev ua lag luam tau pom meej tias muaj kev cuam tshuam tsis zoo rau kev ua lag luam. Txawm hais tias kev khiav hauj lwm tus nqi ntawm domestic phenolic ketone cov nroj tsuag tau txo qis, cov khoom lag luam siab ntawm cov chaw tsim khoom kuj tsawg. Txawm li cas los xij, kev lag luam kev lag luam tsis muaj zog thiab qhov kev thov davhlau ya nyob twg tsis ua haujlwm, ua rau tsis txaus qhov kev txiav txim siab.

Kev lag luam acrylic acid kuj tau cuam tshuam los ntawm kev poob qis, nrog rau cov nqi qhia txog kev poob qis. Raws li kev txheeb cais, tus nqi nruab nrab ntawm acrylic acid nyob rau hauv Shandong hnub Thursday kawg yog 6952.6 yuan / ton, thaum lub sij hawm hnub Thursday tus nqi nruab nrab yog 6450.75 yuan / ton, ib tug txo ntawm 7.22% piv rau lub lim tiam dhau los. Kev lag luam tsis muaj zog yog qhov laj thawj tseem ceeb rau qhov kev poob qis no, nrog rau kev nce siab hauv cov khoom muag. Txhawm rau txhawb nqa cov khoom xa tuaj, lub Hoobkas yuav tsum tau txo tus nqi ntxiv thiab ua cov khoom lag luam emissions. Txawm li cas los xij, vim kev ceev faj txog kev yuav khoom thiab kev lag luam muaj zog tos-thiab-pom kev xav, kev thov kev loj hlob yog txwv. Nws cia siab tias qhov kev thov qis qis yuav tsis zoo dua nyob rau lub sijhawm luv luv, thiab kev lag luam acrylic acid yuav txuas ntxiv kom muaj qhov tsis muaj zog.
Zuag qhia tag nrho, tam sim no isopropanol kev ua lag luam feem ntau tsis muaj zog, thiab kev poob qis ntawm cov khoom siv raw acetone thiab acrylic acid nqi tau ua rau muaj kev nyuaj siab rau kev lag luam isopropanol. Qhov tseem ceeb txo qis ntawm cov khoom siv raw acetone thiab acrylic acid tus nqi tau ua rau kev lag luam tsis muaj zog tag nrho, nrog rau kev xav tau qis qis, ua rau kev lag luam tsis zoo. Cov neeg siv hauv qab thiab cov tub lag luam muaj kev txaus siab yuav khoom tsawg thiab tos-thiab-saib tus cwj pwm ntawm kev ua lag luam, ua rau kev lag luam tsis txaus ntseeg. Nws cia siab tias isopropanol kev ua lag luam tseem yuav tsis muaj zog nyob rau lub sijhawm luv.
Txawm li cas los xij, cov neeg soj ntsuam kev lag luam ntseeg tias txawm hais tias kev lag luam isopropanol tam sim no tab tom ntsib kev poob qis, kuj tseem muaj qee yam zoo. Ua ntej, nrog kev txhim kho tas mus li ntawm lub teb chaws ib puag ncig cov cai, isopropanol, raws li ib puag ncig tus phooj ywg hnyav, tseem muaj qee yam kev loj hlob hauv qee thaj chaw. Thib ob, kev rov qab los ntawm kev tsim khoom lag luam hauv tebchaws thiab thoob ntiaj teb, nrog rau kev txhim kho ntawm thaj chaw tshiab xws li txheej txheej, number case, plastics, thiab lwm yam lag luam, xav tias yuav txhawb kev lag luam isopropanol. Tsis tas li ntawd, qee cov tsoomfwv hauv nroog tau txhawb nqa kev txhim kho ntawm isopropanol ntsig txog kev lag luam, txhaj tshuaj tshiab tseem ceeb rau hauv kev ua lag luam los ntawm kev txhawb nqa txoj cai thiab kev coj ua tshiab.
Los ntawm kev xav ntawm kev ua lag luam thoob ntiaj teb, kev ua lag luam isopropanol thoob ntiaj teb kuj ntsib qee yam kev cov nyom thiab cov hauv kev. Ntawm qhov tod tes, qhov cuam tshuam ntawm yam xws li kev hloov pauv ntawm cov nqi roj thoob ntiaj teb, kev pheej hmoo ntawm thaj chaw, thiab kev tsis paub tseeb hauv kev lag luam sab nraud ntawm isopropanol kev ua lag luam tsis tuaj yeem tsis quav ntsej. Ntawm qhov tod tes, kev kos npe ntawm qee qhov kev cog lus thoob ntiaj teb kev lag luam thiab kev txhawb nqa kev koom tes hauv cheeb tsam kev lag luam tau muab cov hauv kev tshiab thiab kev lag luam loj hlob qhov chaw rau kev xa tawm ntawm isopropanol.
Hauv cov ntsiab lus no, cov tuam txhab lag luam hauv isopropanol kev lag luam yuav tsum tau hloov pauv hloov pauv hauv kev lag luam, ntxiv dag zog rau kev tshawb fawb thiab kev tsim kho thiab cov khoom lag luam tshiab, txhim kho cov khoom zoo thiab cov nqi ntxiv, thiab nrhiav cov ntsiab lus loj hlob tshiab. Nyob rau tib lub sijhawm, ntxiv dag zog rau kev tshawb fawb txog kev lag luam thiab kev sau cov ntaub ntawv, kev tuav lub sijhawm ua lag luam sib txawv, thiab hloov kho cov tswv yim tsim khoom thiab kev muag khoom los txhim kho kev lag luam kev sib tw.
