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 useChina, kunesidingo esikhulu somkhiqizo wawo 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 eJapan futhi ayikakhi imakethe yezimboni.Ngo-2019, isidingo sisonke saseChina se-HBPA singamathani angama-840, kanti ngo-2020, singamathani 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 engamelana 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 kuyalinganisela, 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 wonke, 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.
