Ukususela ngo-2023, ukubuyiselwa kokusetyenziswa kwesiphelo sendlela kuhamba kancinci, kwaye imfuno ye-onstream engalandeli ngokwaneleyo. Kwikota yokuqala, amandla okutsha kwemveliso engama-440000 ye-bisphenol a asebenze, eqaqambisa iimfuno zokuhanjiswa ngokuchasene ne-bisphenol yentengiso. Izinto ezibuthathaka ze-phenol ziyaguquka eziphindaphindiweyo, kwaye iziko elipheleleyo lokuhla lihle liyancipha, kodwa ukuncipha kuncinana kwe-bisphenol A. Ilahleko ye-bisphenol A.
Ukusukela ngo-Matshi, i-bisphenol intengiso inyuke kwaye yawa rhoqo, kodwa uluhlu lwamaxabiso entengiso lupheleleyo lulinganiselwe, phakathi kwe-9250-9800 yuan / ton. Emva kwe-18 ka-Epreli, umoya we-bisphenol "ngequbuliso" uphuculwe, ukonyuka kwemakethi esematshini, kunye ne-dull

Imeko ye-bisphenol yaphukile.

Nge-25 ka-Epreli, i-bisphenol yentengiso eMpuma China iyaqhubeka ukuqinisa, ngelixa i-bisphenol yasekhaya inyuka imarike. Indawo yokubonelela kwimarike iqinile, kwaye umnikelo obambe umthwalo uye watyhilelwa. Ngokukhawuleza nje ukuba abantu kwimarike bafuna ukubuza, baya kuthethathethana nokulandela ngobunono ngokweemfuno zabo. Kwixesha elifutshane, imakethi isebenza ngexabiso eliphezulu, kwaye iikowuteshini zentengiso ziyaqhubeka nokuphakama kwi-10000-10100 yuan / ton!

Okwangoku, inqanaba lemveliso elipheleleyo lokulinganisa i-bisphenol a e-china lijikeleze i-70%, ukuncipha kwamanqaku ali-11 xa kuthelekiswa noMatshi. Ukususela ngo-Matshi, umthwalo we-singoopec sanjung kunye neeyunithi ze-NANGOng Xingchen inciphe, kunye nenqanaba lokusetyenziswa kwe-bispheal ye-bisphenol inciphile ukuya kuthi ga kwiipesenti ezingama-75. I-huizhou zhongxin kunye ne-yanhua polycarbon ivale ngokulandelelana kwesondlo ekupheleni kuka-Matshi nasekuqalekeni kwenqanaba lokusetyenziswa kwe-bisphenol ukuba ngama-70%. Iimveliso zikamelo ikakhulu zizisebenzisa kwaye zibonelela kubathengi bexesha elide, okukhokelela ekunciphiseni kwendawo yendawo. Kwangelo xesha, njengoko kukho imfuneko ye-sporadic yokufumana i-Dowstream, indawo yendawo idlalwa kancinci.

Ukusukela emantla ka-Epreli, ngenxa yokunikezelwa kwekhaya kunye nokungenisa kwakhona kwe-bisphenol a, kunye nokuphehlelelwa kwe-EPOXY i-EPOXY kunye ne-PC, imfuno yemihla ngemihla ye-bisphenol a ngokuthe ngcembe ithathe ibhalansi yonciphiso lwe-inventri. Ukusukela ngoFebruwari, indawo yenzuzo yenzuzo ye-bisphenol a iphantsi, inzondelelo yabasebenzi abathathe inxaxheba inciphile, kwaye uluhlu lweemveliso ezirhwetyiweyo zinciphile. Okwangoku, akukho zibonelelo zamabala kwi-bisphenol, kwaye abanini bamazi bengafuni kuthengiswa, bebonisa injongo ephezulu yokutyhala.

Kwicala elingezantsi, ukusukela ngonyaka wama-2023, ukubuyiselwa kwemfuno yesiphelo sendlela esezantsi kakhulu kunelitye kunokuba bekulindelwe, kwaye ugxininiso lwentengiso ye-Epoxy kunye neemarike ze-EPOXY. I-bisphenol a isetyenziselwa ukulungisa ukusetyenziswa kwemvumelwano, kwaye bambalwa abafuna nje ukuthenga ngexabiso elifanelekileyo. Umthamo wokurhweba wemiyalelo yendawo ulinganiselwe. Okwangoku, inqanaba lokusebenza kwemveliso ye-Epoxy ijikeleze i-50%, ngelixa ishishini lePC lingama-70%. Kutshanje, i-bisphenol a kunye neemveliso ezinxulumene ne-ECH ziye zanda ngaxeshanye, zikhokelela ekunyukeni kweendleko kwi-Epoxy Retin kunye nonyuko oluxineneyo kwintengiso. Nangona kunjalo, bekukho izinto ezimbalwa zokugcina izinto zokugcina i-PC ngaphambi kokuba suku, kunye nokunikezelwa kwemveliso kunye neengcinezelo zemfuno zisekhona. Ngapha koko, izinto ezingafunekiyo i-bisphenol ye-bisphenol iqhubeka ikhula ngamandla, zibonelele kwaye zifuna iingxabano kunye noxinzelelo lweendleko. Amashishini ikakhulu akwisitali esizinzileyo kwaye alindile, kwaye ukhumbule ezantsi kwemfuno ayonelanga, kubangela ukurhweba ngokunqabileyo.
Ngasekupheleni kwenyanga, akukho xinzelelo kukuthunyelwa komnini wenqwelo, kwaye uxinzelelo lweendleko lusekhona. Umnini wempahla unenjongo eyomeleleyo yokutyhala. Nangona kulumkele ukulumkisa ukuba amaxabiso aphezulu asezantsi, ikakhulu ekuthengeni kwimfuno, kunzima ukufumana ixabiso eliphantsi kwintengiso, kwaye kugxilwe kwimarike yemakethi ukuya kumaxabiso aphezulu. Kulindelwe ukuba i-bisphenol a ayizukuqhubeka nokufumana ukugcwala okuqinileyo kwaye inikele ingqalelo ekulandeleni imfuneko yokulandela.
