Rajada Horumarinta ee Hydphenol A (HBPA)

Hydprenol-ka bisphenol a (HBPA) waa noocyo cusub oo guryo cayriin ah oo ku yaal bawdada warshadaha kiimikada ee wanaagsan. Waxaa lagu dhex abuuraa Bisphenol a (BPA) by dareere. Codsigooda asal ahaan waa isku mid. Bisphenol A waxaa inta badan loo isticmaalaa soo saarista polycarbonate, ephoxy Resin iyo agab kale oo polymer ah. Adduunyada, polycarbonate waa qaybta ugu badan ee isticmaalka BPA. In kasta oo ay joogaan Shiinaha, waxaa jira baahi weyn oo loogu talagalay sheygooda oo hoos udhaca, Resiny Resin. Si kastaba ha noqotee, kororka deg-degga ah ee waxsoosaarka Polycarbonarbonarbonarbonarbonarbonarbonarbonarbonarbonarbonarbonarbonarbon, baahida Shiinaha ee ku saabsan BPA ayaa sii kordheysa, iyo qaab dhismeedka istcimaaliga ayaa si tartiib tartiib ah u wada yeeshaan adduunka.

Waqtigan xaadirka ah, Shiinaha ayaa hogaaminaya heerka koritaanka sahayda iyo isticmaalka warshadaha BPA. Ilaa iyo sanadka 2014, baahida guriga ee BPA ayaa guud ahaan sii wata isbeddelka koriinka xasilloon. Sanadka 2018, waxay gaadhay 51.667 milyan oo tan oo tan ah, 2019, waxay gaadhay 11.9511 milyan oo tan, oo ay sanad walba kordhineysay sanadkii 17.01%. Sanadkii 2020, wax soo saarka soosaarka ee Shiinaha ee BPA waxay ahayd 1.4173 milyan oo tan, mugga soo dejinta isla muddadiisu ahayd 595000 tan iyo mudadii, iyo baahida Shiinaha, iyo baahida Shiinaha ee BPA-da ayaa ahayd 1.9993 milyan oo tan ah. Si kastaba ha noqotee, sababta oo ah caqabadaha farsamada ee sare ee soo saarista soosaarka HBPA, suuqa gudaha ayaa muddo dheer ku tiirsanaa dhoofinta Japan mana uusan sameynin suuqa warshadaha. Sanadkii 2019, wadarta guud ee Shiinaha ee HBPA waa qiyaastii 840 tan, 2020, waa qiyaastii 975 tan.

Marka la barbar dhigo badeecadaha resin ee ay sameeyaan bpa, alaabada resin ee ay ku jiraan HBPA waxay leeyihiin faa iidooyinka soo socda: sunta kiimikada, xasilloonida kiimikada, iska caabbinta UV, xasilloonida kuleylka iyo iska caabbinta cimilada. Marka laga reebo in astaamaha jireed ee sheyga la daaweeyay ay la mid yihiin, iska caabbinta cimilada si weyn ayaa loo xoojiyaa. Sidaa darteed, HBPA Epoxy Resin, sida resin cimilada u caabbinta ah, ayaa inta badan loo isticmaalaa soosaarida dhamaadka iyo aaladaha arjiga, oo ah qalabka korantada ee qiimaha sare leh, qaybo ka mid ah dahabka, qaybaha aaladda caafimaadka, isku-darka iyo beero kale.

Waqtigan xaadirka ah, sahayda iyo baahida suuqa caalamiga ah ee HBPA ayaa asal ahaan isu dheellitiran, laakiin wali waxaa jira farqiga u dhexeeya suuqa gudaha. Sanadka 2016, baahida guriga ayaa ahayd qiyaastii 349 tan, wax soo saarkuna waxay ahayd 62 tan oo keliya. Mustaqbalka, oo leh ballaarinta tartiib-tartiib ee qiyaasta dalabka ee hoos udhaca, HBPA gudaha HBPA waxay leedahay rajo ballaaran oo horumarineed. Saldhigga baahida weyn ee suuqa BPA waxay bixisaa meel ballaadhan oo ballaaran oo loogu talagalay alaabada HBPA ee suuqa sare. Iyada oo la casriyeeyo warshadaha joogtada ah ee adduunka, horumarinta deg-degga ah ee agabyada cusub iyo hagaajinta tartiib-tartiib ee shuruudaha dhamaadka macaamiisha iyo waxqabadka ee HBPA ay sidoo kale ka badan tahay soosaarka suuqa sare ee BPA iyo dhiirrigelinta soosaarka guud ee Shiinaha iyo qiimaha hoose ee Shiinaha.
