Tsuas muaj ob peb hnub ua haujlwm nyob rau lub Kaum Ib Hlis, thiab thaum kawg ntawm lub hli, vim muaj kev txhawb nqa nruj hauv kev lag luam hauv tsev ntawm bisphenol A, tus nqi tau rov qab mus rau 10000 yuan. Raws li niaj hnub no, tus nqi ntawm bisphenol A nyob rau sab hnub tuaj Tuam Tshoj ua lag luam tau nce mus rau 10100 yuan / ton. Txij li thaum tus nqi poob qis dua 10000 yuan cim thaum pib ntawm lub hli, nws tau rov qab mus rau ntau dua 10000 yuan thaum kawg ntawm lub hli. Saib rov qab ntawm kev ua lag luam sib txawv ntawm bisphenol A nyob rau lub hli dhau los, cov nqi tau qhia qhov hloov pauv thiab hloov pauv.

Nyob rau hauv thawj ib nrab ntawm lub hlis no, lub lag luam tus nqi nruab nrab ntawm bisphenol A hloov downwards. Qhov laj thawj tseem ceeb yog tias tus nqi ntawm cov khoom siv raw ntawm cov phenolic ketones tseem pheej poob qis, thiab tus nqi them nyiaj yug rau lub khw muag khoom bisphenol A tau poob qis. Nyob rau tib lub sijhawm, tus nqi ntawm ob cov khoom lag luam downstream, epoxy resin thiab PC, kuj tseem poob qis, ua rau muaj kev txhawb nqa tsis txaus rau tag nrho bisphenol A kev lag luam saw, kev lag luam poob qis, kev muag khoom tsis zoo ntawm cov tuav, nce cov khoom muag siab, nqes nqes, thiab kev ua lag luam. kev xav raug cuam tshuam.
Nyob rau hauv nruab nrab thiab lig lub hlis, tus nqi nruab nrab ntawm bisphenol A nyob rau hauv lub lag luam maj mam rebounded. Ntawm qhov tod tes, cov khoom siv raw khoom phenolic ketone tus nqi tau rov qab los, ua rau kev lag luam poob ntau tshaj 1000 yuan. Tus neeg muag khoom tus nqi siab yog siab, thiab qhov kev xav ntawm tus nqi txhawb nqa yog maj mam nce. Ntawm qhov tod tes, tau muaj kev nce hauv cov cuab yeej siv hauv tsev kaw, thiab qhov kev nyuaj siab ntawm cov neeg muag khoom los yuav cov khoom lag luam tau poob qis, ua rau cov nqi nce ntxiv. Nyob rau tib lub sijhawm, muaj qee qhov kev xav tau nruj qis qis, thiab nws nyuaj rau nrhiav cov khoom siv qis qis, yog li kev tsom mus rau kev sib tham tau maj mam hloov mus rau sab saud.
Txawm hais tias tus nqi theoretical tus nqi ntawm kev lag luam hauv tsev bisphenol A tau poob qis los ntawm 790 yuan / ton piv rau lub hli dhau los, tus nqi nruab nrab ntawm cov theoretical txhua hli yog 10679 yuan / ton. Txawm li cas los xij, kev lag luam bisphenol A tseem ua rau poob ze li 1000 yuan. Raws li niaj hnub no, qhov theoretical tag nrho cov txiaj ntsig ntawm kev lag luam bisphenol A yog -924 yuan / ton, tsuas yog nce me ntsis ntawm 2 yuan / ton piv rau lub hli dhau los. Tus neeg muag khoom raug kev poob qis, yog li muaj kev hloov kho tsis tu ncua rau kev pib ua haujlwm. Ntau qhov kev kaw tsis tau npaj tseg ntawm cov cuab yeej siv hauv lub hlis tau txo qis tag nrho kev ua haujlwm ntawm kev lag luam. Raws li kev txheeb cais, qhov nruab nrab ntawm kev ua haujlwm ntawm bisphenol A kev lag luam lub hlis no yog 63.55%, qhov txo qis ntawm 10.51% ntawm lub hli dhau los. Cov khoom siv chaw nres tsheb muaj nyob hauv Beijing, Zhejiang, Jiangsu, Lianyungang, Guangxi, Hebei, Shandong thiab lwm qhov chaw.
Los ntawm qhov kev xav qis qis, epoxy resin thiab PC lag luam tsis muaj zog, thiab tag nrho cov nqi tsom mus rau qhov tsis muaj zog. Kev nce hauv chaw nres tsheb ntawm cov khoom siv PC tau txo qis qhov kev thov nruj rau bisphenol A. Qhov kev txiav txim txais tos ntawm cov tuam txhab epoxy resin tsis yog qhov zoo tagnrho, thiab kev lag luam kev tsim khoom tau khaws cia nyob rau theem qis. Kev yuav khoom ntawm cov khoom siv raw bisphenol A yog qhov txwv tsis pub, feem ntau yog vim qhov yuav tsum tau ua raws li tus nqi tsim nyog. Kev ua haujlwm ntawm kev lag luam epoxy resin lub hlis no yog 46.9%, nce ntawm 1.91% piv rau lub hli dhau los; Kev khiav haujlwm ntawm PC kev lag luam yog 61.69%, qhov txo qis ntawm 8.92% ntawm lub hli dhau los.
Thaum kawg ntawm lub Kaum Ib Hlis, tus nqi lag luam ntawm bisphenol A rov qab mus rau 10000 yuan cim. Txawm li cas los xij, ntsib qhov xwm txheej tam sim no ntawm kev poob thiab qhov kev xav tau qis qis, kev ua lag luam tseem ntsib kev nyuaj siab. Kev txhim kho yav tom ntej ntawm bisphenol A kev ua lag luam tseem yuav tsum tau ua tib zoo saib rau ntau yam xws li kev hloov pauv ntawm cov khoom siv raw, cov khoom siv thiab kev xav tau, thiab kev xav ntawm kev lag luam.
