Raws li cov khoom siv raw ntawm PC, bisphenol A tau nce zuj zus, thiab cov khoom lag luam tseem nruj. Ntxiv rau PC, epoxy cob kuj tseem siv nws, thiab tus nqi ntawm epoxy resin tau nce ntau dua PC! Tom ntej no, peb saib bisphenol kev ua lag luam niaj hnub no.
Thaum Lub Kaum Hli 13, Sinopec Mitsui' s bisphenol A quotation tau tsa los ntawm 100 los siv 12,500 yuan/tuj. Tam sim no, lub tuam txhab' s bisphenol A cov khoom lag luam feem ntau yog muab rau cov neeg siv khoom mus sij hawm ntev, thiab 120,000 tons/xyoo bisphenol A cog tau ua haujlwm tiav.
Tam sim no tus nqi ntawm epoxy cob kuj tseem ua tiav dhau lub hom phiaj ntawm 20,000 yuan ib tuj. Nws tau cia siab tias kev lag luam hauv tsev yuav nyob hauv lub xeev no rau ib lub sijhawm. Tus nqi qis yog qhov nyuaj nrhiav, thiab cov nqi epoxy resin yuav ib txwm nyob siab.
Tus nqi ntawm epoxy cob yuav ib txwm siab. Qhov tseeb, muaj teeb meem ntawm cov khoom siv raw. Epoxy resin yog cov khoom ntawm epichlorohydrin thiab bisphenol A lossis polyol. Cov khoom siv raw propylene hauv epichlorohydrin yog qhov pib tsis ntau. Floating, tus nqi ntawm glycerin tau nce, yog li tus nqi yog qhov ruaj khov.
Tab sis bisphenol A tsis ruaj khov. Ua ntej Hnub National, tus nqi ntawm bisphenol A tau nce thaum cov tuam txhab tau ntim ntau ntau.
Tam sim no, hauv kev ua lag luam, cov tuam txhab tau dhau los ua ntau dua thiab tiv taus cov nqi siab ntawm cov khoom siv raw, thiab kev muab cov tshuaj epoxy cob yog qhov nruj. Nws tuaj yeem hais tau tias cov khoom siv ntau tshaj qhov khoom siv. Txawm hais tias kev kis mob tau yooj yim dua, qhov cuam tshuam ib txwm muaj nyob hauv khw. Hauv lub sijhawm tsis ntev los no, tus nqi ntawm epoxy resin tau hloov pauv ntawm qib siab. Nws tseem tsim nyog los daws qhov teeb meem ntawm cov khoom siv raw thiab cov lag luam nqes peev kom sai li sai tau.
Hauv lub sijhawm luv, PC cov nqi lag luam txuas ntxiv mus rau qib siab, thiab qhov xwm txheej nruj tsis tau yooj yim nyob rau lub sijhawm luv. Cov khoom siv raw bisphenol A muab siab, thiab cov tuam txhab hauv tsev tseem muaj chav rau cov khoom lag luam yav dhau los, thiab lub hom phiaj kom poob qis hauv lub sijhawm luv yog tsis muaj zog.
