Pamsika wonse wa bisphenol A wa chaka chino, mtengo wake ndi wotsika kwambiri kuposa 10000 yuan (mtengo wa matani, womwewo pansipa), womwe ndi wosiyana ndi nthawi yaulemerero yopitilira 20000 yuan zaka zam'mbuyomu. Wolembayo amakhulupirira kuti kusagwirizana pakati pa kupereka ndi kufunikira kumalepheretsa msika, ndipo makampani akupita patsogolo pansi pa zovuta. Mitengo yochepera 10000 yuan ikhoza kukhala yodziwika bwino pamsika wamtsogolo wa bisphenol A.
Makamaka, choyamba, mphamvu yopanga bisphenol A yawonjezeka kwambiri. Kuyambira kuchiyambi kwa chaka chino, mphamvu yopangira bisphenol A ikupitilirabe kutulutsidwa, ndipo mphamvu zonse zopanga mabizinesi awiriwa zafika matani 440000 pachaka. Kukhudzidwa ndi izi, China okwana chaka kupanga mphamvu bisphenol A anafika matani miliyoni 4.265, kuwonjezeka pafupifupi 55% pachaka, ndi pafupifupi mwezi kupanga anafika matani 288000, kuika latsopano mbiri yakale. M'tsogolomu, kukula kwa kupanga bisphenol A sikunayime, ndipo zikuyembekezeredwa kuti mphamvu yatsopano yopangira bisphenol A idzapitirira matani 1.2 miliyoni chaka chino. Ngati atayikidwa pakupanga pa nthawi yake, mphamvu yopanga pachaka ya bisphenol A ku China idzakula mpaka matani 5.5 miliyoni, kuwonjezeka kwa chaka ndi 45%. Panthawiyo, chiopsezo chotsika mtengo pansi pa 9000 yuan chidzapitirirabe.
Kachiwiri, phindu lamakampani silikhala labwino. Kuyambira kuchiyambi kwa chaka chino, chitukuko cha makampani a bisphenol A chikuchepa. Kuchokera pakuwona zinthu zakumtunda, Msika wa phenolic ketone umatanthauzidwa ngati "msika wa phenolic ketone" M Zomwe zimachitika m'gawo loyamba, mabizinesi a phenolic ketone anali otayika, ndipo m'gawo lachiwiri, mabizinesi ambiri adatembenuka. zopindulitsa zabwino. Komabe, mkatikati mwa Meyi, msika wa phenolic ketone udatsika, pomwe acetone idatsika ndi yuan yopitilira 1000 ndipo phenol idatsika ndi yuan yopitilira 600, kupititsa patsogolo phindu labisphenol a mabizinesi. Komabe, ngakhale zili choncho, bizinesi ya bisphenol idakalipobe mozungulira mtengo. Pakadali pano, zida za bisphenol a zikupitilizabe kusamalidwa, ndipo kuchuluka kwa magwiridwe antchito amakampani kwatsika. Nthawi yokonza yatha Pambuyo pa tsiku lomaliza, zikuyembekezeredwa kuti chiwerengero chonse cha bisphenol A chidzawonjezeka, ndipo mpikisano wothamanga ukhoza kupitiriza kuwonjezeka panthawiyo. Maonedwe a phindu akadali opanda chiyembekezo.
Chachitatu, chithandizo chamankhwala chimafunikira. Kuphulika kwamphamvu kwa bisphenol A sikunafanane ndi kukula kwa kufunikira kwa mtsinjewu munthawi yake, zomwe zidapangitsa kuti pakhale kutsutsana kwazomwe zimafunikira, zomwe ndizofunikira kwambiri pakukhazikika kwa msika. Kutsika kwa madzi a polycarbonate (PC) bisphenol A kumapitilira 60%. Kuyambira 2022, makampani a PC alowa m'gulu lazinthu zogaya chakudya, ndipo kufunikira kocheperako kumakhala kocheperako kuposa kuchuluka kwazinthu. Kusagwirizana pakati pa kupezeka ndi kufunikira kwa msika ndizodziwikiratu, ndipo mitengo ya PC ikupitilirabe kutsika, zomwe zikukhudza chidwi cha mabizinesi kuti ayambe kumanga. Pakalipano, kugwiritsa ntchito mphamvu zopangira ma PC ndi zosakwana 70%, zomwe zimakhala zovuta kusintha pakapita nthawi. Kumbali ina, ngakhale kutsika kwa epoxy resin kupanga mphamvu kukukulirakulirabe, kufunikira kwamakampani opanga zokutira ndikuchepera, ndipo ndizovuta kukonza kwambiri ma terminals monga zamagetsi, zamagetsi, ndi zida zophatikizika. Zolepheretsa zofunidwa zikadalipo, ndipo kuchuluka kwamakampani omwe amagwiritsa ntchito mphamvu ndi ochepera 50%. Ponseponse, PC yotsika ndi utomoni wa epoxy sungathe kuthandizira bisphenol A.
