Imakethe yomhlaba wonke yei-phthalic anhydridekulindeleke ukuthi kube nokukhula okuphawulekayo eminyakeni ezayo, ngokwezindaba zakamuva zemakethe zonyaka zango-2024. I-Phthalic anhydride iyikhemikhali ebalulekile ephakathi nendawo esetshenziswa ekukhiqizeni imikhiqizo ehlukahlukene, okuhlanganisa ama-plasticizers, ama-resin, nodayi. Isidingo esikhulayo sale mikhiqizo esetshenziswa ekugcineni kuzo zonke izimboni ezinjengezezimoto, ezokwakha, nezimpahla zabathengi kuqhuba ukukhula kwemakethe ye-phthalic anhydride.
Enye yezindlela ezibalulekile ezakha imakethe ukwanda kwesidingo samapulasitiki angenawo i-phthalate. Ngokuqwashisa okwandayo mayelana nezingozi ezingaba khona zezempilo nezemvelo ezihlobene nama-phthalates, kukhona ukushintshela ekusetshenzisweni kwamanye ama-plasticizer asuselwe emithonjeni ye-bio-based noma engeyona i-phthalate. Lo mkhuba kulindeleke ukuthi ube nomthelela ekuguquguqukeni kwemakethe futhi uqhubekisele phambili ukuthuthukiswa kokwakheka okusha nemikhiqizo eminyakeni ezayo.
Enye into ebalulekile enomthelela emakethe ukwanda kokugxila kwezinqubo zokukhiqiza ezizinzile. Abakhiqizi batshala imali kubuchwepheshe obunciphisa umthelela wemvelo wokukhiqizwa kwe-phthalic anhydride, njengokwamukelwa kwezinqubo ze-catalytic oxidation kanye nokusetshenziswa kwe-feedstocks evuselelekayo. Lezi zinhlelo kulindeleke ukuthi ziqhubekisele phambili imakethe ekuxazululeni izisombululo ezisimeme futhi ezinobungani bemvelo, ezihambisana nomgomo womhlaba wonke wokukhiqiza amakhemikhali aluhlaza.
Mayelana nokuguquguquka kwesifunda, i-Asia-Pacific kulindeleke ukuthi ihlale iyimakethe ehamba phambili ye-phthalic anhydride, eqhutshwa ukuthuthuka kwezimboni kanye nokufudukela emadolobheni emazweni afana neChina neNdiya. Umkhakha wokukhiqiza oqinile wesifunda kanye nesisekelo esikhulayo sabathengi sibhebhezela isidingo se-phthalic anhydride kuzo zonke izinhlelo zokusebenza.
Uma ubheka phambili, imakethe ye-phthalic anhydride ilungele ukukhula okuqinile, isekelwa ukuthuthuka okuqhubekayo kwezobuchwepheshe, ukuvela kwezindawo zokulawula, kanye nokushintshashintsha okuthandwayo kwabathengi. Kodwa-ke, izinselelo ezinjengamanani entengo yempahla eluhlaza kanye nemikhawulo yokulawula kuma-phthalates ezifundeni ezithile kungaba nomthelela ekukhuleni kwemakethe ngokwezinga elithile.
Sengiphetha, imakethe ye-phthalic anhydride isethelwe ukufakaza intuthuko namathuba aphawulekayo eminyakeni ezayo, iqhutshwa ukuvela kwemikhuba yezimboni kanye nokuphishekela izixazululo ezizinzile nezintsha. Ababambiqhaza kulo lonke uchungechunge lwenani, kusukela kubakhiqizi kuya kubasebenzisi bokugcina, kuzodingeka bazivumelanise nalezi zinguquko futhi basebenzise amathuba avelayo emakethe.
