Ithemba Lokuthuthukiswa Kwe-Hydrogenated Bisphenol A(HBPA)

I-Hydrogenated Bisphenol A(HBPA) iyinto entsha ebalulekile ye-resin eluhlaza emkhakheni wemboni yamakhemikhali emihle. Ihlanganiswa kusuka ku-Bisphenol A(BPA) nge-hydrogenation. Ukusetshenziswa kwabo kuyafana. I-Bisphenol A isetshenziswa kakhulu ekukhiqizeni i-polycarbonate, i-epoxy resin nezinye izinto ze-polymer. Emhlabeni, i-Polycarbonate iyinkambu esetshenziswa kakhulu ye-BPA. Ngenkathi ise-China, kunesidingo esikhulu somkhiqizo wayo osakazwa phansi, i-epoxy resin. Kodwa-ke, ngokukhula okusheshayo kwamandla okukhiqiza i-polycarbonate, isidingo saseChina se-BPA siyaqhubeka nokwanda, futhi nesakhiwo sokusetshenziswa sihlangana kancane kancane nomhlaba.

Njengamanje, i-China ihola izinga lokukhula lokuhlinzekwa kanye nokusetshenziswa kwemboni ye-BPA. Kusukela ngo-2014, isidingo sasekhaya se-BPA ngokuvamile sigcine umkhuba wokukhula ozinzile. Ngo-2018, ifinyelele amathani ayizigidi ezingama-51.6675, kwathi ngo-2019, yafinyelela kumathani ayizigidi eziyi-11.9511, nokunyuka konyaka ngonyaka ngama-17.01%. Ngo-2020, umkhiqizo waseChina wasekhaya we-BPA wawungamathani ayizigidi eziyi-1.4173, umthamo wokungenisa ngesikhathi esifanayo wawungamathani angama-595000, umthamo wokuthekelisa wawungamathani ayi-13000, kanti isidingo saseChina se-BPA sasingamathani ayizigidi eziyi-1.9993. Kodwa-ke, ngenxa yezithiyo eziphezulu zobuchwepheshe ekukhiqizweni kwe-HBPA, imakethe yasekhaya sekuyisikhathi eside ithembele ekuthengisweni okuvela e-Japan futhi ayikakhi imakethe yezimboni. Ngo-2019, inani eliphelele lesidingo se-HBPA laseChina licishe libe ngamathani angama-840, kanti ngo-2020, lingamathani angama-975.

Uma kuqhathaniswa nemikhiqizo ye-resin ehlanganiswe yi-BPA, imikhiqizo ye-resin ehlanganiswe yi-HBPA inezinzuzo ezilandelayo: ukungabi nabuthi, ukuqina kwamakhemikhali, ukumelana ne-UV, ukuzinza okushisayo kanye nokumelana nesimo sezulu. Ngaphandle kokuthi izici ezibonakalayo zomkhiqizo ophulukisiwe ziyefana, ukumelana nesimo sezulu kuthuthukiswa kakhulu. Ngakho-ke, i-HBPA epoxy resin, njenge-epoxy resin emelana nesimo sezulu, isetshenziswa kakhulu ezindaweni zokukhiqiza nezisetshenziswa ezisezingeni eliphezulu, njengokupakishwa kwe-LED enenani eliphakeme, izinto zokufaka ugesi ezinenani eliphakeme, ukumbozwa kwe-fan blade, izingxenye zemishini yezokwelapha, izinhlanganisela kanye ezinye izinkambu.

Njengamanje, ukuhlinzekwa kanye nesidingo semakethe ye-HBPA yomhlaba wonke kuyalingana, kodwa lisekhona igebe emakethe yasekhaya. Ngo-2016, isidingo sasekhaya sasicishe sibe ngamathani angama-349, kanti umphumela wawungamathani angama-62 kuphela. Ngokuzayo, ngokwanda kancane kancane kwesikali sesicelo esingezansi, i-HBPA yasekhaya inamathuba abanzi okuthuthukiswa. Isisekelo esikhulu sesidingo semakethe ye-BPA sinikeza enye indawo ebanzi yemikhiqizo ye-HBPA emakethe esezingeni eliphezulu. Ngokuthuthuka okuqhubekayo kwemboni ye-resin yomhlaba, ukuthuthuka okusheshayo kwezinto ezintsha kanye nokwenza ngcono kancane kancane kwezidingo zabathengi bokugcina ngekhwalithi nokusebenza komkhiqizo, izici ezinhle kakhulu ze-HBPA zizothatha indawo yengxenye yesabelo semakethe esiphezulu se-BPA kanye thuthukisa futhi ukukhiqizwa kwe-resin yaseChina kanye nokusetshenziswa komfula ongezansi.
