Rajada Horumarinta ee Bisphenol A(HBPA)

Hydrogenated Bisphenol A (HBPA) waa shey cusub oo cusub oo muhiim ah oo ceeriin ah oo ku saabsan warshadaha kiimikada ee wanaagsan. Waxay ka samaysan tahay Bisphenol A (BPA) iyadoo loo marayo hydrogenation. Codsigoodu asal ahaan waa isku mid. Bisphenol A waxaa inta badan loo isticmaalaa soo saarista polycarbonate, resin epoxy iyo qalabyada kale ee polymer. Adduunka, Polycarbonate waa goobta ugu weyn ee isticmaalka BPA. Halka Shiinaha, waxaa jira baahi weyn oo loo qabo badeecadeeda hoos u socota, resin epoxy. Si kastaba ha noqotee, kororka degdega ah ee awoodda wax-soo-saarka polycarbonate, baahida Shiinaha ee BPA ayaa sii socota inay kordhiso, iyo qaab-dhismeedka isticmaalka ayaa si tartiib tartiib ah ula mid ah adduunka.

Waqtigan xaadirka ah, Shiinaha ayaa hogaaminaya heerka kobaca saadka iyo isticmaalka warshadaha BPA. Laga soo bilaabo 2014, baahida gudaha ee BPA waxay guud ahaan ilaalisay isbeddel koritaan oo deggan. Sannadkii 2018, waxa uu gaadhay 51.6675 million ton, 2019, waxa uu gaadhay 11.9511 million ton, iyada oo sanadba sanadka ka dambeeya uu kordhay 17.01%. 2020, wax soo saarka gudaha Shiinaha ee BPA wuxuu ahaa 1.4173 milyan oo tan, mugga soo dejinta isla muddadaas wuxuu ahaa 595000 tan, mugga dhoofinta wuxuu ahaa 13000 tan, iyo baahida Shiinaha ee BPA waxay ahayd 1.9993 milyan oo tan. Si kastaba ha ahaatee, caqabadaha sare ee farsamada ee hortaagan wax-soo-saarka HBPA, suuqa waddanku wuxuu muddo dheer ku tiirsanaa badeecadaha laga keeno Japan oo aan weli samayn suuqa warshadaha. Sannadka 2019, guud ahaan baahida Shiinaha ee HBPA waa ilaa 840 tan, sanadka 2020, waa ilaa 975 tan.

Marka la barbardhigo alaabada xabagta ee ay farsamaysay BPA, alaabta resin ee ay samaysay HBPA waxay leeyihiin faa'iidooyinka soo socda: sun la'aan, xasiloonida kiimikada, caabbinta UV, xasilloonida kulaylka iyo caabbinta cimilada. Marka laga reebo in sifooyinka jireed ee alaabta la daaweeyay ay isku mid yihiin, caabbinta cimilada si weyn ayaa loo xoojiyay. Sidaa darteed, xabagta epoxy HBPA, sida resin epoxy adkaysi u ah cimilada, waxaa inta badan loo isticmaalaa in dhamaadka-dhamaadka sare beeraha iyo codsiyada, sida baakadaha LED-qiimaha sare, alaabta dahaarka korantada oo qiimo sare leh, daahan marawaxad, qaybaha qalabka caafimaadka, ka kooban iyo beeraha kale.

Waqtigan xaadirka ah, sahayda iyo baahida suuqa caalamiga ah ee HBPA asal ahaan waa isku dheeli tiran tahay, laakiin weli waxaa jira farqi suuqa gudaha ah. Sannadkii 2016, baahida waddanku waxay ahayd qiyaastii 349 tan, wax soo saarkuna wuxuu ahaa 62 tan oo keliya. Mustaqbalka, iyadoo si tartiib tartiib ah loo ballaarinayo cabbirka codsiga hoose, HBPA gudaha waxay leedahay rajooyin horumarineed oo ballaaran. Saldhigga baahida weyn ee suuqa BPA waxa ay siisaa boos ballaadhan oo beddelka ah ee alaabada HBPA ee suuqa-dhamaadka sare. Iyada oo kor u kaca joogtada ah ee warshadaha resin-ka adduunka, horumarinta degdega ah ee agabka cusub iyo hagaajinta tartiib tartiib ah ee shuruudaha macaamiisha dhamaadka tayada iyo waxqabadka, sifooyinka wanaagsan ee HBPA waxay sidoo kale bedeli doontaa qayb ka mid ah saamiga suuqa-dhamaadka sare ee BPA iyo sii kor u qaadida wax soo saarka resin ee Shiinaha iyo codsiga hoose.
