Txij li thaum Lub Ob Hlis, kev lag luam hauv tsev propylene oxide tau pom qhov nce tsis tu ncua, thiab nyob rau hauv kev sib koom ua ke ntawm tus nqi sab, muab khoom thiab kev xav tau thiab lwm yam zoo, kev ua lag luam propylene oxide tau qhia txog kev nce siab txij li lub Ob Hlis kawg. Raws li lub Peb Hlis 3, tus nqi xa tawm ntawm propylene oxide hauv Shandong tau nce mus rau 10900-11000 yuan / ton, qhov siab tshiab txij li Lub Rau Hli 2022, 1100 yuan / ton lossis 11% siab dua tus nqi ntawm Lub Ob Hlis 23.
Los ntawm qhov kev xav ntawm kev muab khoom, Ningbo Zhenhai Refining thiab Chemical Plant Phase I tau raug kaw rau kev saib xyuas thaum Lub Ob Hlis 24. Lub sijhawm kwv yees yog li ib thiab ib nrab lub hlis. Kev ua tau zoo ntawm cov chaw muab kev pabcuam hauv kev lag luam yav qab teb tau nruj, thaum cov kev hloov pauv ntawm cov khoom lag luam sab qaum teb tsis loj. Qee lub tuam txhab muaj kev ua haujlwm tsis zoo, thiab cov khoom muag qis ntawm cov lag luam muaj kev muag khoom tsawg. Muaj qee qhov kev txhawb nqa zoo hauv lub khw muag khoom; Tsis tas li ntawd, kev tsim cov peev txheej tshiab tsis yog raws li qhov xav tau. Tianjin Petrochemical Cog tau raug kaw thaum nruab nrab Lub Ob Hlis txhawm rau tshem tawm qhov tsis xws luag. Satellite Petrochemical tswj kev ua haujlwm qis. Txawm hais tias cov khoom tsim nyog tau tsim, lawv tsis tau xa tawm ntau ntau. Shandong Qixiang thiab Jiangsu Yida cov nroj tsuag tseem tsis tau rov ua dua tshiab. Jincheng Petrochemical xav tias yuav muab tso rau hauv kev tsim khoom hauv lub Peb Hlis.
Nyob rau hauv cov nqe lus ntawm kev thov, tom qab lub caij nplooj ntoos hlav Festival nyob rau hauv Tuam Tshoj, tag nrho cov rov qab los ntawm domestic thov thiab xa tawm nyob rau hauv ntau yam domestic industries yog tsawg tshaj li qhov xav tau. Txawm li cas los xij, vim yog tus nqi siab ntawm propylene oxide, tus nqi ntawm cov dej hauv qab polyether tau nce siab, kev ua lag luam kuj zoo nyob rau hauv kev yuav khoom thiab cov khoom lag luam, thiab tus nqi ntawm propylene oxide tseem siab. Kev txhawb nqa los ntawm kev xav ntawm kev yuav nce thiab tsis yuav qis, tsis ntev los no downstream polyether tuam txhab ua raws li ntau thiab ntau incrementally, tsav lub lag luam ntawm propylene oxide mus txuas ntxiv txhim kho.
Nyob rau hauv cov nqe lus ntawm tus nqi, nyob rau hauv nam ntawm propylene, tsis ntev los no tus me nyuam lub siab ntawm propylene ntau lawm tuam txhab uas muag tau eased thiab qhov kev thov tau rebounded. Tsav los ntawm kev rov qab los ntawm polypropylene yav tom ntej, tag nrho kev lag luam kev lag luam huab cua tau zoo tuaj, thiab qhov chaw hloov pauv tau thawb. Raws li lub Peb Hlis 3, tus nqi lag luam tseem ceeb ntawm propylene hauv xeev Shandong tau 7390-7500 yuan / tuj; Nyob rau hauv cov nqe lus ntawm cov kua chlorine, vim yog kev txhim kho ntawm downstream auxiliary chlorine noj cov cuab yeej, sab nrauv muag ntim ntawm cov kua chlorine tau poob, txhawb tus nqi nce mus rau theem siab ntawm 400 yuan / ton dua. Kev txhawb nqa los ntawm kev nce nqi ntawm cov kua chlorine, raws li lub Peb Hlis 3, PO tus nqi ntawm chlorohydrin txoj kev nce li ntawm 4% piv rau Lub Ob Hlis 23.
Hais txog cov txiaj ntsig, txij li lub Peb Hlis 3, PO cov txiaj ntsig ntawm chlorohydrin txoj kev yog kwv yees li 1604 yuan / ton, nce 91% txij Lub Ob Hlis 23.
Nyob rau hauv lub neej yav tom ntej, kev lag luam propylene ntawm cov khoom siv raw khoom kawg yuav nce ntxiv me ntsis, cov kua chlorine ua lag luam tuaj yeem tswj xyuas kev ua haujlwm zoo, thiab kev txhawb nqa ntawm cov khoom siv raw khoom kawg tseem pom tseeb; Tus neeg muag khoom tseem nruj, tab sis nws tseem yuav tsum tau tos thiab pom kev ua haujlwm ntawm cov khoom siv tshiab tso rau hauv kev ua haujlwm; Ntawm qhov kev thov sab, nyob rau hauv lub caij nyoog xav tau ntawm lub caij ntuj sov lub caij ntuj sov, qhov kev xav tau ntawm lub khw muag khoom ntawm polyether tuaj yeem tuav lub zog rov qab qeeb, tab sis vim tias tam sim no yuam tus nqi siab dua ntawm polyether, qhov kev xav ntawm kev yuav khoom yuav muaj qhov sib txawv qeeb; Ntawm qhov tod tes, tseem muaj kev txhawb nqa rau cov khoom lag luam luv luv. Nws cia siab tias kev lag luam propylene oxide yuav tuav ruaj khov, nruab nrab thiab muaj zog ua haujlwm nyob rau lub sijhawm luv luv, thiab peb yuav tos rau cov nqes dej polyether xaj.
