Lub lim tiam no, kev ua lag luam epoxy resin hauv tebchaws tau sib xyaw. Thaum lub lim tiam, qhov chaw nruab nrab ntawm lub ntiajteb txawj nqus ntawm kev ua lag luam kua resin tsis muaj zog, thiab kev ua lag luam resin khov kho tau tshaj tawm tias muaj kev nce ntxiv. Txij li thaum kaw lub Ib Hlis 7, tus nqi tseem ceeb ntawm cov kua resin hauv kev ua lag luam Sab Hnub Tuaj Suav teb yog rau kev siv ntawm 20,500-21,500 yuan / ton hauv cov thoob khib nyiab. Hauv cov ntaub ntawv raw, cov khoom siv raw bisphenol A tseem ceeb tsis poob thiab rov qab los, thaum lwm cov khoom siv raw epichlorohydrin poob dua. Hauv cov ntaub ntawv ntawm kev muab khoom thiab kev thov, kev ua lag luam epoxy resin tau ua haujlwm ruaj khov thaum lub lim tiam, thiab tus nqi ua haujlwm tau nce ntxiv tas li. Txawm li cas los xij, kev ua lag luam epoxy resin tam sim no tau nkag mus rau lub caij tsis muaj zog thiab kev thov tau qeeb.

Thaum pib xyoo 2021, qhov kev tsom mus rau kev lag luam epoxy resin tau nce siab. Ua tsaug rau qhov kev nres luv luv ntawm cov khoom siv raw khoom thiab kev tsis txaus ntawm cov khoom siv, kev txhawb nqa tus nqi tam sim no tau muaj zog, thiab kev muab cov tuam txhab tsim cov resin tau nce siab.

Cov noodles nyoos
Bisphenol A: Lub lim tiam no, kev ua lag luam bisphenol A tau hloov pauv thiab rov qab los. Thaum lub lim tiam, kev ua lag luam bisphenol A tau hloov pauv nws qhov kev poob qis thiab kev muab khoom maj mam nce. Cov khoom siv raw phenol khiav tsis muaj zog, qhov chaw ntawm lub ntiajteb txawj nqus ntawm acetone txav mus rau saum, thiab sab nqi feem ntau tau txhawb nqa. Hais txog kev muab khoom, lub Hoobkas bisphenol A tau hloov pauv ntau dua lub lim tiam no, thiab qib kev ua haujlwm tau poob qis. Tag nrho cov nqi ua haujlwm yog nyob ib puag ncig 60%. Ntawm lawv, Nantong Xingchen lub nra hnyav tau poob qis mus rau 40%. Sinopec Mitsubishi lub Hoobkas tau kaw ib ntus, thiab kev muab khoom ntawm qhov chaw tau nruj. Hais txog kev thov, cov PCs downstream tseem ceeb thawj zaug poob qis thiab tom qab ntawd nce siab, kev ua lag luam tau txais, thiab epoxy resins tsis tau ua raws li. Txij li thaum kaw ntawm Lub Ib Hlis 7, tus nqi sib tham tseem ceeb ntawm BPA hauv East China yuav raug xa ntawm RMB 12,900-13,000 / ton.

Epichlorohydrin: Lub lim tiam no, epichlorohydrin ua haujlwm tsis zoo. Thaum lub lim tiam, cov chaw tsim khoom tsis muaj kev txhawb nqa zoo, thiab kev ua lag luam epichlorohydrin txuas ntxiv poob qis. Cov khoom siv raw propylene thiab glycerin tau teeb tsa ua ntu zus, thiab sab nqi hloov pauv me ntsis. Ntawm sab kev muab khoom, lub lim tiam no lub Hoobkas epichlorohydrin tseem qis, tus nqi ua haujlwm ntawm kev lag luam yog li 45%, Hoobkas Shandong Binhua rov pib dua, thiab Ningbo Huanyang kaw rau kev saib xyuas. Hais txog kev thov, kev ua lag luam resin qis dua txias, thiab kev thov nyuaj rau txhim kho. Txij li thaum kaw lub Ib Hlis 7, tus nqi sib tham tseem ceeb ntawm epichlorohydrin hauv East China tau xa tuaj ntawm 11300-11400 yuan / ton.

Sab muab khoom
Lub lim tiam no, tus nqi ua haujlwm ntawm lub Hoobkas ua kua roj hmab tau tswj hwm ntawm kwv yees li 60%, thiab cov khoom siv hauv qhov chaw muaj ntau heev. Nws Tuam Tshoj Capital Chemical Industry tseem nyob rau hauv lub xeev kaw, thiab hnub pib tsis tau txiav txim siab. Nws nyuaj rau nce qhov hnyav ntawm lub Hoobkas ua kua roj hmab khov kho, thiab tus nqi ua haujlwm yog kwv yees li 40%. Ntawm lawv, Huangshan Jinfeng kev kho dua tshiab nres, thiab qhov chaw sib tham tag nrho nyuaj rau txhim kho.

Sab kev thov
Tam sim no, kev ua lag luam resin tseem nyob rau lub caij tsis muaj neeg xav tau, cov lus nug hauv qab tsis zoo siab, thiab cov kev lag luam tsis tshua muaj. Kev xav tsis zoo ntawm kev lag luam tsuas yog nce ntxiv, thiab kev ua haujlwm ceev faj, thiab qhov xwm txheej tam sim no nyuaj rau hloov.

Kev kwv yees yav tom ntej

Xyoo 2020, kev ua lag luam resin tau siv ib xyoo "khawv koob". Thaum pib ntawm xyoo 2021, epoxy resin zoo li tsis muaj zog nyob rau hauv kev txhawb nqa ntawm tus nqi, tab sis undercurrents yeej nce siab. Cov yam tseem ceeb uas cuam tshuam rau kev ua lag luam tam sim no yog raws li nram no:
Ntawm sab khoom siv raw, bisphenol A tuaj yeem piav qhia tias yog "tus pab txhawb" tseem ceeb rau kev lag luam resin nce hauv lub voj voog no. Txawm li cas los xij, qhov cuam tshuam zoo ntawm cov khoom siv no yog txwv. Lwm cov khoom siv raw epichlorohydrin qhia txog qhov sib txawv nqaim, thiab kev txhawb nqa tus nqi tsis zoo; sab khoom siv, kev ua lag luam Hauv qhov xwm txheej ntawm kev ua haujlwm khoom siv sab hauv ruaj khov, cov khoom siv resin txaus, thiab nws nyuaj rau txhawb nqa nws; sab kev thov, tus nqi thiab tsis muaj qhov xwm txheej ua lag luam nyuaj rau tawg, cov lag luam downstream siv feem ntau ntawm cov khoom muag, thiab qib kev thov tseem tsis zoo. Nws xav tias kev lag luam epoxy resin hauv tsev yuav tswj hwm qhov xwm txheej hloov pauv hauv lub sijhawm luv luv, thiab kev ua raws li tseem yuav tsum tau them sai sai rau cov khoom siv raw thiab kev muab khoom thiab kev thov.
