1,Ukuhlaziywa Kwesenzo Semakethe

Kusukela ngo-Ephreli, imakethe yasekhaya ye-bisphenol A ikhombise ukukhuphuka okucacile. Lo mkhuba usekelwa ikakhulukazi ukukhuphuka kwamanani ezinto ezimbili zokusetshenziswa kwe-phenol ne-acetone. Intengo ecashuniwe evamile e-East China ikhuphuke yafinyelela cishe ku-9500 yuan/ton. Ngasikhathi sinye, ukusebenza okuphezulu okuqhubekayo kwamanani kawoyela ongahluziwe nakho kunikeza isikhala esikhuphukayo semakethe ye-bisphenol A. Kulo mongo, imakethe ye-bisphenol A ibonise ukuthambekela kokululama.

2,Ukwehla komthwalo wokukhiqiza kanye nomthelela wokunakekelwa kwemishini

Muva nje, umthwalo wokukhiqizwa kwe-bisphenol A e-China wehlile, futhi amanani acashunwe abakhiqizi nawo akhuphuke ngokufanele. Kusukela ekupheleni kukaMashi kuya ekuqaleni kuka-April, isibalo sokuvalwa kwemboni ye-bisphenol A yasekhaya ukuze silungiswe sikhule, okuholele ekushodekeni kwesikhashana kokuhlinzekwa kwezimakethe. Ukwengeza, ngenxa yesimo samanje sokwenza ukulahlekelwa kwamafekthri asekhaya, izinga lokusebenza kwemboni lehle laya cishe ku-60%, lafinyelela ezingeni eliphansi elisha ezinyangeni eziyisithupha. Kusukela mhla ziyi-12 kuMbasa, umthamo wokukhiqiza wezindawo zokupaka usufinyelele amathani acishe abe yisigidi, okubalelwa ku-20% yenani eliphelele lokukhiqiza ekhaya. Lezi zinto zihlangene zenyuse intengo ye-bisphenol A.

3,Isidingo esiphansi somfula sivimbela ukukhula

Nakuba imakethe ye-bisphenol A ibonisa ukukhuphuka, ukwehla okuqhubekayo kwesidingo esiphansi somfula kuyikhinyabeze ukukhuphuka kwayo. I-Bisphenol A isetshenziswa kakhulu ekukhiqizeni i-epoxy resin kanye ne-polycarbonate (PC), futhi lezi zimboni ezimbili ezansi nomfula zenza cishe u-95% wengqikithi yomthamo wokukhiqiza we-bisphenol A. Nokho, ezikhathini zamuva nje, kube nokulinda okuqinile-futhi. -bona imizwa emakethe ye-PC engezansi, futhi okokusebenza kungase kulungiswe endaweni eyodwa, okuholela ekwenyukeni okuncane kuphela kwemakethe. Ngesikhathi esifanayo, imakethe ye-epoxy resin nayo ikhombisa ukuthambekela okubuthakathaka, njengoba isidingo sesiphetho sisonke sivilapha futhi izinga lokusebenza kwezitshalo ze-epoxy resin liphansi, okwenza kube nzima ukuhambisana nokukhuphuka kwe-bisphenol A. Ngakho-ke, i isidingo sisonke se-bisphenol A emikhiqizweni esezansi nomfula sinciphile, okube yisici esiyinhloko esikhawulela ukukhula kwayo.

4,Isimo Samanje Nezinselelo Zomkhakha We-Bisphenol A YaseShayina

Kusukela ngo-2010, umthamo wokukhiqiza waseShayina we-bisphenol A ukhule ngokushesha futhi manje usungumkhiqizi omkhulu emhlabeni wonke kanye nomnikezeli we-bisphenol A. Kodwa-ke, ngokwanda komthamo wokukhiqiza, inkinga yezinhlelo zokusebenza ezigxile ezansi nomfula iya ngokuya igqama. Njengamanje, inqwaba yezinto ezisetshenziswayo zamakhemikhali ayisisekelo kanye nemikhiqizo yamakhemikhali esezingeni eliphakathi kuya kwesisezingeni eliphansi ngokuvamile isesimweni sensalela noma insalela enkulu. Naphezu kwamathuba amakhulu okuthengwa kwempahla yasekhaya, indlela yokuvuselela amandla okusetshenziswa nokukhuthaza ukusungulwa kwemboni nentuthuko kuyinselele enkulu ebhekene nemboni ye-bisphenol A.

5,Izitayela namathuba entuthuko yesikhathi esizayo

Ukuze unqobe inkinga yokusetshenziswa okugxilile, imboni ye-bisphenol A idinga ukukhulisa imizamo yayo yokuthuthukisa kanye nokukhiqiza emikhiqizweni engaphansi komfula njengama-flame retardants kanye nezinto ezintsha ze-polyetherimide PEI. Ngokusungula izinto ezintsha zobuchwepheshe kanye nokuthuthukiswa komkhiqizo, nwebisa izinkambu zokusetshenziswa kwe-bisphenol A futhi uthuthukise ukuncintisana kwayo ezimakethe. Ngesikhathi esifanayo, imboni nayo idinga ukunaka izinguquko ezifunwayo zemakethe futhi ilungise amasu okukhiqiza ukuze ivumelane nezinguquko zemakethe.

Kafushane, nakuba imakethe ye-bisphenol A isekelwa ukukhuphuka kwezintengo zempahla eluhlaza kanye nokunikezwa okuqinile, isidingo esibuthaka esisezansi nomfula kuseyisici esibalulekile esikhawulela ukukhula kwayo. Ngokuzayo, ngokunwetshwa kwamandla okukhiqiza kanye nezindawo zokufaka izicelo ezansi nomfula, imboni ye-bisphenol A izobhekana namathuba amasha okuthuthukiswa nezinselele. Imboni idinga ukusungula izinto ezintsha njalo futhi ilungise amasu ukuze ivumelane nezinguquko zemakethe futhi izuze intuthuko esimeme.
