Msika wapadziko lonse lapansi waphthalic anhydrideakuyembekezeka kuchitira umboni kukula kwakukulu m'zaka zikubwerazi, malinga ndi nkhani zaposachedwa zamsika zapachaka za 2024. Phthalic anhydride ndi mankhwala ofunikira kwambiri omwe amagwiritsidwa ntchito popanga zinthu zosiyanasiyana, kuphatikiza mapulasitiki, utomoni, ndi utoto. Kuchuluka kwazinthu zogwiritsidwa ntchito kumapeto kwa mafakitale monga magalimoto, zomangamanga, ndi zinthu zogula kukuyendetsa kukula kwa msika wa phthalic anhydride.
Chimodzi mwazinthu zazikulu zomwe zikupanga msika ndikukwera kwa kufunikira kwa mapulasitiki opanda phthalate. Ndi chidziwitso chokulirapo pazathanzi komanso kuwopsa kwa chilengedwe komwe kumakhudzana ndi ma phthalates, pali kusintha kogwiritsa ntchito mapulasitiki ena opangidwa kuchokera ku bio-based or non-phthalate sources. Izi zikuyembekezeka kukhudza momwe msika ukuyendera ndikuyendetsa chitukuko cha zatsopano ndi zogulitsa m'zaka zikubwerazi.
Chinthu chinanso chofunikira chomwe chikuthandizira msika ndikuchulukirachulukira kwazinthu zokhazikika zopangira. Opanga akuika ndalama muukadaulo womwe umachepetsa kukhudzidwa kwa chilengedwe ndi kupanga phthalic anhydride, monga kutengera njira za catalytic oxidation ndi kugwiritsa ntchito zakudya zongowonjezera. Izi zikuyembekezeka kuyendetsa msika ku mayankho okhazikika komanso ochezeka ndi zachilengedwe, mogwirizana ndi kukakamiza kwapadziko lonse kupanga mankhwala obiriwira.
Pankhani ya kayendetsedwe ka zigawo, Asia-Pacific ikuyembekezeka kukhalabe msika waukulu wa phthalic anhydride, motsogozedwa ndi kukwera kwachangu komanso kukwera kwamatauni m'maiko ngati China ndi India. Magawo opanga mphamvu m'derali komanso kuchuluka kwa ogula akukulitsa kufunikira kwa phthalic anhydride pamagwiritsidwe osiyanasiyana.
Kuyang'ana m'tsogolo, msika wa phthalic anhydride watsala pang'ono kukula, mothandizidwa ndi kupita patsogolo kwaukadaulo, kusinthika kwamalo owongolera, ndikusintha zomwe ogula amakonda. Komabe, zovuta monga mitengo yosasinthika yazinthu zopangira komanso zoletsa zama phthalates m'magawo ena zitha kukhudza kukula kwa msika pamlingo wina.
Pomaliza, msika wa phthalic anhydride ukuyembekezeka kuchitira umboni zochitika ndi mwayi muzaka zikubwerazi, motsogozedwa ndi zomwe zikuchitika m'makampani komanso kufunafuna mayankho okhazikika komanso anzeru. Ogwira nawo ntchito pazambiri zamtengo wapatali, kuyambira opanga mpaka ogwiritsa ntchito omaliza, adzafunika kusintha kusinthaku ndikupindula ndi zomwe zikuyembekezeka pamsika.
