Kev tsim kev cia siab ntawm hydrogenated bisphenol a (HBPA)

Hydrogenated Bisphenol A (HBPA) yog qhov tseem ceeb tshiab cov khoom lag luam tshiab raw nyob hauv kev ua teb ntawm tshuaj lom neeg zoo tshuaj. Nws yog synthesized los ntawm bisphenol a (bpa) los ntawm hydrogenation. Lawv daim ntawv thov yog ib qho zoo ib yam. Bisphenol Ib feem ntau yog siv nyob rau hauv kev tsim polycarbonate, epoxy cob thiab lwm cov ntaub ntawv polymer. Nyob hauv lub ntiaj teb, Polycarbonate yog qhov loj tshaj kev noj ntawm BPA. Thaum nyob hauv Suav teb, muaj ib qho kev thov loj rau nws cov khoom hauv qab, epoxy cob. Txawm li cas los xij, nrog kev nce qib sai ntawm Polycarbonate ntau lawm, cov neeg xav tau rau BPA tseem nce ntxiv, thiab cov qauv kev siv tau hloov pauv nrog lub ntiaj teb.

Tam sim no, Tuam Tshoj tab tom ua tus nqi ntawm kev muab khoom thiab kev noj ntawm BPA kev lag luam. Txij li xyoo 2014, cov kev thov hauv tsev rau BPA feem ntau tswj cov kev loj hlob ruaj khov. Nyob rau hauv 2018, nws tau txog 51.6675 lab tons, thiab xyoo 2019, nws tau mus txog 11.9511 lab tons, nrog ib xyoos-nyob rau xyoo 17.01%. Hauv 2020, Tuam Tshoj cov zis hauv tsev ntawm BPA yog 1.4173 lab tons, cov ntaub ntawv xa tawm nyob rau hauv tib lub sijhawm yog 13000 tons, thiab Tuam Tshoj txoj kev thov rau BPA yog 1.993 lab tons. Txawm li cas los xij, vim muaj kev cuam tshuam ntau rau HBPA, kev ua lag luam hauv tsev tau ua haujlwm ntev rau ntawm Nyij Pooj thiab tseem tsis tau tsim cov lag luam lag luam. Hauv 2019, Tuam Tshoj tag nrho cov kev thov rau HBPA yog kwv yees li 840 tons, thiab hauv 2020, nws yog kwv yees li 975 tons.

Piv nrog cov khoom lag luam hluav taws xob synthesized los ntawm BPA, cov khoom cob qhia synthesized los ntawm cov txiaj ntsig hauv qab no: UV tsis muaj tshuaj, UV tsis muaj tshuaj, thermal tsis kam thiab huab cua tsis kam. Tsuas yog tias cov khoom siv lub cev tsuas yog cov khoom noj zoo sib xws, tej huab cua tsis yog txhim kho. Yog li ntawd, HBPa Epoxy Resin, raws li huab cua resist epoxy cob, yog cov khoom siv hluav taws xob zoo, xws li cov khoom siv kho mob, xws li cov khoom siv kho mob, cov khoom siv kho mob thiab lwm thaj teb.

Tam sim no, cov khoom siv thiab kev thov ntawm kev ua lag luam HBPA HBPA yog qhov sib npaug, tab sis tseem muaj qhov sib txawv hauv kev ua lag luam hauv tsev. Xyoo 2016, cov kev thov hauv tsev tau hais txog 349 tons, thiab cov zis tsuas yog 62 tons. Nyob rau yav tom ntej, nrog maj mam nthuav dav ntawm ownstream daim ntawv thov nplai, hauv tsev HBPA muaj kev txhim kho dav dav. Qhov kev thov khoom loj ntawm BPA kev lag luam muab qhov chaw xaiv dav rau HBPA cov khoom lag luam hauv kev ua lag luam siab. Nrog kev txhim kho txuas ntxiv ntawm lub ntiaj teb kev lag luam, kev txhim kho sai ntawm HBPA yuav tau hloov ib feem ntawm BPA thiab ntxiv txhawb suav cov khoom lag luam ntawm Tuam Tshoj dua thiab cov khoom siv hauv qab.
