Kev lag luam thoob ntiaj teb rauphthalic anhydridexav tias yuav pom kev loj hlob tseem ceeb nyob rau hauv lub xyoo tom ntej, raws li cov xov xwm kev lag luam tshiab tshaj plaws rau xyoo 2024. Phthalic anhydride yog ib qho tshuaj tseem ceeb nruab nrab siv hauv kev tsim khoom ntawm ntau yam khoom, suav nrog plasticizers, resins, thiab dyes. Qhov kev thov nce ntxiv rau cov khoom siv kawg no thoob plaws kev lag luam xws li tsheb, kev tsim kho, thiab cov neeg siv khoom lag luam yog tsav kev loj hlob ntawm kev lag luam phthalic anhydride.
Ib qho ntawm cov kev hloov pauv tseem ceeb hauv kev ua lag luam yog qhov kev thov nce ntxiv rau phthalate-dawb plasticizers. Nrog rau kev loj hlob ntawm kev paub txog kev noj qab haus huv thiab ib puag ncig kev pheej hmoo cuam tshuam nrog phthalates, muaj kev hloov pauv mus rau kev siv lwm yam plasticizers muab los ntawm bio-based lossis non-phthalate qhov chaw. Cov qauv no xav tias yuav cuam tshuam rau kev lag luam kev lag luam thiab tsav kev txhim kho cov qauv tshiab thiab cov khoom lag luam hauv xyoo tom ntej.
Lwm qhov tseem ceeb uas cuam tshuam rau kev ua lag luam yog kev tsom mus rau kev tsim khoom kom ruaj khov. Cov neeg tsim khoom lag luam tau nqis peev hauv cov thev naus laus zis uas txo cov kev cuam tshuam ib puag ncig ntawm phthalic anhydride ntau lawm, xws li kev siv cov txheej txheem catalytic oxidation thiab siv cov khoom siv txuas ntxiv. Cov phiaj xwm no yuav tsum tau tsav lub lag luam mus rau cov kev daws teeb meem zoo dua qub thiab eco-phooj ywg, ua ke nrog lub ntiaj teb thawb rau kev tsim tshuaj ntsuab.
Hais txog kev muaj zog hauv cheeb tsam, Asia-Pacific tau cia siab tias yuav nyob twj ywm ua lag luam tseem ceeb rau phthalic anhydride, uas tau tsav los ntawm kev lag luam sai thiab kev lag luam hauv nroog hauv cov teb chaws xws li Tuam Tshoj thiab Is Nrias teb. Lub cheeb tsam kev lag luam muaj zog thiab kev loj hlob ntawm cov neeg siv khoom lag luam tau txhawb nqa qhov kev thov rau phthalic anhydride thoob plaws ntau daim ntawv thov.
Saib tom ntej, kev ua lag luam rau phthalic anhydride yog npaj rau kev loj hlob tsis tu ncua, txhawb nqa los ntawm kev siv thev naus laus zis tsis tu ncua, hloov kho thaj chaw tswj hwm, thiab hloov cov neeg siv khoom nyiam. Txawm li cas los xij, cov kev sib tw xws li cov nqi raw khoom tsis hloov pauv thiab kev tswj hwm kev txwv ntawm phthalates hauv qee thaj chaw tuaj yeem cuam tshuam kev lag luam loj hlob rau qee qhov.
Hauv kev xaus, kev lag luam phthalic anhydride tau teeb tsa los ua pov thawj qhov tseem ceeb ntawm kev txhim kho thiab cov hauv kev hauv xyoo tom ntej, uas tau tsav los ntawm kev hloov pauv kev lag luam thiab kev nrhiav cov kev daws teeb meem zoo thiab tsim kho tshiab. Cov neeg muaj feem cuam tshuam thoob plaws tus nqi saw, los ntawm cov tuam txhab lag luam mus rau cov neeg siv kawg, yuav tsum tau hloov kho rau cov kev hloov pauv no thiab ua kom muaj txiaj ntsig ntawm cov kev cia siab tshiab hauv kev ua lag luam.
