Kuyo yonke imarike yebisphenol A yalo nyaka, ixabiso ngokwesiseko lingaphantsi kwe-10000 yuan (ixabiso letoni, elifana ngezantsi), elahlukileyo kwixesha elizukileyo elingaphezu kwama-20000 yuan kwiminyaka edlulileyo.Umbhali ukholelwa ukuba ukungalingani phakathi konikezelo kunye neemfuno zithintela imarike, kwaye ishishini liqhubela phambili phantsi koxinzelelo.Amaxabiso angaphantsi kwe-10000 yuan anokuba yinto eqhelekileyo kwimarike ye-bisphenol A yexesha elizayo.
Ngokukodwa, okokuqala, amandla okuvelisa i-bisphenol A anyuke kakhulu.Ukususela ekuqaleni kwalo nyaka, amandla okuvelisa i-bisphenol A aqhubekile nokukhululwa, kunye nomthamo wemveliso yonyaka yamashishini amabini afikelela kwiitoni ze-440000.Ukuchatshazelwa koku, umthamo wemveliso wonyaka waseTshayina we-bisphenol A ufikelele kwi-4.265 yezigidi zeetoni, ukwanda malunga ne-55% ngonyaka, kwaye imveliso yenyanga yenyanga ifikelele kwiitoni ezingama-288000, ibeka imbali entsha.Kwixesha elizayo, ukwandiswa kwemveliso ye-bisphenol A akuyekanga, kwaye kulindeleke ukuba amandla amatsha okuvelisa i-bisphenol A aya kudlula i-1.2 yezigidi zeetoni kulo nyaka.Ukuba kufakwe kwimveliso ngexesha, umthamo wonyaka wemveliso ye-bisphenol A e-China uya kwanda ukuya malunga ne-5.5 yezigidi zeetoni, ukunyuka konyaka-ngonyaka ngama-45%.Ngelo xesha, umngcipheko wokuhla kwexabiso elingaphantsi kwe-9000 yuan liya kuqhubeka liqokelela.
Okwesibini, iingeniso zenkampani azinathemba.Ukusukela ekuqaleni kwalo nyaka, ukuchuma kwekhonkco leshishini le-bisphenol A liye lehla.Ukususela kumbono wezinto eziluhlaza ezinyukayo, Imarike ye-phenolic ketone ichazwa ngokuthi "imarike ye-phenolic ketone" M Isiqhelo kukuba kwikota yokuqala, amashishini e-phenolic ketone ayesisiseko sokulahlekelwa, kwaye kwikota yesibini, amaninzi amashishini ajika. iingeniso ezintle.Nangona kunjalo, phakathi kukaMeyi, imarike ye-phenolic ketone yaphuka ngendlela ehlayo, kunye ne-acetone ewela ngaphezu kwe-yuan ye-1000 kunye ne-phenol ewela ngaphezu kwe-yuan ye-600, iphucula ngokuthe ngqo inzuzo ye-bisphenol amashishini.Nangona kunjalo, nangona kunjalo, i-bisphenol ishishini lisajikeleza kumgca weendleko.Okwangoku, izixhobo ze-bisphenol ziyaqhubeka nokugcinwa, kwaye izinga lokusebenzisa umthamo weshishini lehlile.Ixesha lokugcinwa liphelile Emva komhla wokugqibela, kulindeleke ukuba ukunikezelwa ngokubanzi kwe-bisphenol A kuya kwanda, kwaye uxinzelelo lokukhuphisana lunokuqhubeka lukhula ngelo xesha.Imbonakalo yengeniso ayikabi nethemba.
Okwesithathu, inkxaso yemfuno ebuthathaka.Ukukhula kwemveliso ye-bisphenol A kusilele ukuhambelana nokukhula kwemfuno esezantsi ngexesha elifanelekileyo, okukhokelela ekuchaselweni okucacileyo kwemfuno yobonelelo, eyona nto ibalulekileyo ekusebenzeni okuphantsi komgangatho wentengiso.Ukusetyenziswa okusezantsi kwepolycarbonate (PC) bisphenol A kubalela ngaphezu kwe-60%.Ukusukela ngo-2022, ishishini lePC lingene kumjikelo wokugaya umthamo wokuvelisa isitokhwe, kunye nemfuno yesiphelo esisezantsi kunokongezwa kobonelelo.Ukuchasana phakathi konikezelo kunye nemfuno kwimarike kucacile, kwaye amaxabiso ePC ayaqhubeka nokuhla, okuchaphazela umdla wamashishini ukuqalisa ukwakhiwa.Okwangoku, izinga lokusetyenziswa kwamandla okuvelisa i-PC lingaphantsi kwe-70%, okunzima ukuyiphucula kwixesha elifutshane.Kwelinye icala, nangona umthamo wemveliso ye-epoxy resin esezantsi iqhubeka nokukhula, imfuno yeshishini lee-terminal coatings iyacotha, kwaye kunzima ukuphucula kakhulu ukusetyenziswa kwe-terminal efana ne-elektroniki, i-elektroniki, kunye nezixhobo ezidibeneyo.Izithintelo zecala lemfuno zisekhona, kwaye izinga lokusetyenziswa kwamandla kwishishini lingaphantsi kwama-50%.Ngokubanzi, i-PC esezantsi kunye ne-epoxy resin ayinakuxhasa i-bisphenol A eluhlaza.
