Xyoo 2022, kev lag luam tshuaj lom neeg hauv tsev tau pom tias muaj kev poob qis. Hauv qhov xwm txheej ntawm kev nce thiab nqis, kev ua tau zoo ntawm kev lag luam tshuaj lom neeg tshiab zoo dua li kev lag luam tshuaj lom neeg ib txwm muaj thiab ua tus thawj coj hauv kev lag luam.
Lub tswv yim ntawm lub zog tshiab yog tsav, thiab cov khoom siv raw upstream tau nce ntxiv. Raws li cov ntaub ntawv txheeb cais, tsib yam khoom siv tshuaj lom neeg saum toj kawg nkaus hauv xyoo 2022 yog lithium hydroxide, lithium carbonate (cov khoom lag luam), butadiene, lithium iron phosphate, thiab phosphate ore. Ntawm lawv, tshwj tsis yog phosphorus ore koom nrog lub tswv yim ntawm lub zog tshiab. Xyoo 2022, tsav los ntawm kev lag luam tsheb fais fab tshiab, tus nqi ntawm lithium hydroxide, lithium carbonate, thiab lithium iron phosphate, uas muaj feem cuam tshuam nrog lithium roj teeb, tau qhia txog kev nce ntxiv. Raws li cov khoom uas muaj kev sib raug zoo nrog cov tsheb fais fab tshiab, butadiene tau mus txog 144% hauv thawj ib nrab ntawm xyoo 2022. Phosphorus ore tau txais txiaj ntsig los ntawm kev nce ntxiv ntawm kev thov rau phosphate chiv thiab cov peev txheej tsawg, thiab tau txuas ntxiv nce txij li xyoo 2021.
Kev lag luam tshuaj lom neeg ib txwm muaj kev cuam tshuam dav dav. Xyoo 2022, feem ntau ntawm cov khoom siv tshuaj lom neeg ib txwm muaj kev poob qis, thiab qhov cuam tshuam ntawm cov saw hlau kev lag luam tau pom tseeb. Piv txwv li, qhov poob qis hauv 1,4-butanol, tetrahydrofuu, N, N-di metamimamamide (DMF), dichlorogenesis, sulfuric acid, acetic acid, hydrochloric acid, thiab lwm yam, qhov poob qis yog 68%, 68%, 61, feem. %, 60%, 56%, 52%, 45%. Tsis tas li ntawd, qhov poob qis ntawm cov khoom xws li du anhydride, sulfur, titanium liab, thiab phenol yog 22% txog 43%. Los ntawm cov qauv ntawm cov khoom no, nws tuaj yeem pom tias qhov nce ntxov ntawm cov khoom siv tshuaj lom neeg ib txwm muaj tau pib poob qis, cov khoom xav tau qaug zog ib qho tom qab ib qho, thiab ib zaug ua rau muaj kev cuam tshuam thoob ntiaj teb ntawm cov saw hlau khoom koom tes.
Cov khoom siv raw yooj yim tau ruaj khov rau theem siab thiab feem ntau rov qab mus rau txoj cai ntawm kev ua lag luam. Lwm yam ntxwv ntawm kev ua lag luam khoom siv tshuaj hauv xyoo 2022 yog tias cov khoom siv raw yooj yim tau ruaj khov ntawm theem nruab nrab mus rau theem siab, thiab ntaus lub siab tshiab hauv thawj ib nrab ntawm lub xyoo, thiab ib nrab xyoo tom qab tau rov zoo. Txawm hais tias tus nqi ntawm qee cov peev txheej loj, cov organic, inorganic, thiab cov chiv tau poob rau hauv ib nrab xyoo tom qab, lawv tau rov qab los rau lub sijhawm tom qab, thiab feem ntau rov qab mus rau txoj cai ntawm kev ua lag luam. Piv txwv li, qhov nce txhua xyoo yog 13%, 12%, 9%, thiab 5% ntawm pyrine, benzide, nitric acid, thiab aniline, uas tau poob qis thaum lub khw siab hauv nruab nrab-2022 lossis Lub Kaum Hli. Vim tias cov khoom siv tshuaj no yog qhov xav tau dav rau cov khoom siv raw yooj yim, lawv tseem tuaj yeem tswj hwm txoj haujlwm ua lag luam muaj zog tom qab kev hloov kho poob qis. Ntxiv rau, cov khoom xws li cycloidone, benzene ntshiab, ethylene oxide, styrene, thiab acryline tau poob qis los ntawm 14%, 10%, 9%, 5%, thiab 4%, raws li. Tom qab cov kev nce siab no, lawv tau poob qis mus rau hauv 14% ntawm qhov nce thiab qhov poob qis hauv 14%. Tus nqi kiag li yog nyob rau hauv nruab nrab-mus-siab txoj haujlwm, thiab nws ruaj khov. Lub luag haujlwm ntawm kev lag luam kev muab khoom thiab kev thov kev cai maj mam txhim kho.
Kev tshuaj xyuas dav dav qhia tau hais tias xyoo 2022, kev ua lag luam tshuaj lom neeg yuav qhia txog kev rov qab los ntawm kev ua lag luam rov qab mus rau qhov muaj laj thawj thiab ua raws li cov cai ntawm kev ua lag luam. Tib lub sijhawm, qhov kev kwv yees ntawm kev ua lag luam tau txias zuj zus, uas yog qhov pom tseeb tshwj xeeb hauv kev ua lag luam tshuaj lom neeg ib txwm muaj. Saib mus rau yav tom ntej, cov khoom siv raw khoom yooj yim yuav poob qis thiab ruaj khov hauv xyoo 2023, cov khoom siv tshuaj lom neeg ib txwm tsis txiav txim siab qhov ua tau ntawm kev sib koom ua ke, cov khoom siv hluav taws xob tshiab nyuaj rau qhia txog kev nce hauv xyoo 2022, tab sis qhov kev cia siab ntawm kev txhim kho tseem muaj kev cia siab.
