Kuyambira Okutobala 2022, msika wapakhomo wa bisphenol A watsika kwambiri, ndipo udakhalabe wokhumudwa pambuyo pa Tsiku la Chaka Chatsopano, zomwe zimapangitsa msika kukhala wovuta kusinthasintha.Pofika pa Januware 11, msika wapakhomo wa bisphenol A udasinthiratu m'mbali, malingaliro odikira ndikuwona a omwe adatenga nawo gawo pamsika sanasinthe, zoyambira pamsika zidasintha pang'ono, malingaliro ogula a ogula anali osamala, ndipo msika wanthawi yayitali udasintha. mtunda wopapatiza.Kutsika kwapansi kumakhudzidwa makamaka ndi kutsutsana pakati pa zopereka ndi zofunikira, ndipo n'zovuta kuthandizira kumtunda ndi kumunsi kwa mayendedwe a mafakitale.

Mphamvu yopangira bisphenol A ikupitilira kukula, ndipo mphamvu yamagetsi ikadalipo
Kuyambira Okutobala 2022, kupezeka kwa bisphenol A kwakula kwambiri, kuphatikiza matani 200000/chaka a Luxi Chemical Group Co., Ltd., matani 240000/chaka cha Wanhua Chemical Group Co., Ltd., ndi matani 680000/chaka cha Jiangsu. Ruiheng New Material Technology Co., Ltd. Komabe, zida zapakhomo zidasungidwa kangapo mu Novembala, kutayika kunali kochepa kwambiri kuposa kukula kwa kupanga, komanso kupezeka kwapakhomo kwa bisphenol A kunakula kwambiri.Poyerekeza ndi kutulutsa kwapakati pamwezi kwa matani 1.82 miliyoni m'nthawi yapitayi, kuchuluka kwa gawo lonse lachinayi kunakula kwambiri.
Mu 2023, bisphenol A yaku China ikadali ndi kukula kwatsopano.Zikumveka kuti mphamvu yopanga bisphenol A idzawonjezeka ndi matani 610000 mu 2023, kuphatikiza matani 200000 pachaka ku Guangxi Huayi, matani 170000 / chaka ku South Asia Plastics, matani 240000 / chaka kwa Wanhua, ndi 680000 kotala lachinayi la matani 202 Akuti chiwerengero cha anthu chidzafika matani 5.1 miliyoni / chaka mu 2023, ndi kuwonjezeka kwa chaka ndi chaka pafupifupi 38%.Pakalipano, chuma chili mu nthawi yobwezeretsa, ndipo pali zosatsimikizika zosiyanasiyana mu theka loyamba la chaka, ndipo kukakamizidwa kopereka chifukwa cha kuwonjezeka kosalekeza kwa mphamvu zopanga kudakalipo.
Ndondomeko zingapo zakulitsa msika, ndipo kufunikira kwachuma kwabwerera pang'onopang'ono

Zochitika zaumoyo wa anthu zikadali ndi chiwopsezo chachikulu pakukula kwachuma chapakhomo komanso kubwezeretsanso kufunikira kwa mafakitale omaliza, makamaka mu theka loyamba la 2023, zomwe zizikhalabe cholinga chakukonzanso msika.Ngakhale ndondomeko zosiyanasiyana zakhazikitsidwa kuti ziwonjezeke msika, kubwezeretsanso kufunikira kumafunikirabe nthawi yopumula.Kufuna ndi kugwiritsidwa ntchito kwapansi pamtsinje kukuchepa.Kuyambira Novembala mpaka Tsiku la Chaka Chatsopano, zinthu zambiri zama PC zidagaya zopangira zomwe zili mgululi, ndipo cholinga chogula chidafowoka.Ndi kuchepa kwa ma terminal oda, kutsika kwa epoxy resin ndi zinthu zina zidatsikanso.Malinga ndi kuwunika kwa mabungwe azamalonda, madzi a epoxy resin ku East China atsika ndi 25% kuyambira kotala lachinayi, ndipo zinthu zama PC zidatsika ndi 8%.Pambuyo pa Tsiku la Chaka Chatsopano, kukonzekera kwazinthu zamakampani opanga magetsi akumtunda kwayenda bwino, koma kusinthasintha kwa msika sizodziwikiratu.
Mtengo wa bisphenol A unatsika kwambiri kuposa wa zopangira, ndipo phindu linatsika
Kuchokera pazithunzi zamakampani a bisphenol A, zitha kuwoneka kuti kuchepa kwa bisphenol A ndikokulirapo kuposa phenol yaiwisi ndi acetone, ndipo phindu la bisphenol A limachepa.Makamaka ndi kubwereranso kwa msika wa phenol / acetone mu December, bisphenol A sinawuke pansi pa chithandizo cha mtengo, koma anakhalabe wopsinjika maganizo pansi pa kukakamizidwa, ndipo phindu la malonda linalowa m'malo otayika.
M'madera awiri akumunsi kwa mtsinje, kuchepa kwa epoxy resin sikunali kosiyana kwambiri ndi zopangira, pamene kutsika kwa zinthu za PC kunali kotsika kwambiri kusiyana ndi zopangira chifukwa cha kukhudzidwa kwa zosowa zawo ndi zofuna zawo.Poyamba, PC inali yotayika chifukwa cha kukhudzidwa kwa bisphenol A yamtengo wapatali yamtengo wapatali, ndipo PC yotsika kwambiri inasanduka phindu m'miyezi iwiri kumapeto kwa chaka, ndipo phindu lalikulu la malonda linakula.Ndi kutulutsidwa kosalekeza kwa mphamvu zapamwamba-pansi ndi kugawanso phindu la makampani a bisphenol A, mphamvu ya node iliyonse idzawonjezeka kwambiri mu 2023. Kusintha kwa kaphatikizidwe ndi kufunikira kwa mbali ndi phindu pa node iliyonse kungaganizidwe.

Kukula kwa msika, BPA ikukakamizidwa mtsogolo

Pamene Chikondwerero cha Spring chikuyandikira, kufunikira kwa msika kumakhala kwaulesi, kukambirana kwa msika wa bisphenol A kumakhala chete, ndipo mbali yofunikira ya epoxy resin mumsika wamagetsi amagetsi akuyenda bwino pang'ono, koma kukula kwa kufunikira ndikocheperako kusiyana ndi kufalikira kwa magetsi. mbali, zomwe zimakhala zovuta kupanga chithandizo cha bisphenol A. Kutsika konse kwa phenol ndi acetone pamtengo wamtengo wapatali kumakhala kwakukulu kuposa kuwuka.Msika wasiya kugwa ndikuyambiranso posachedwa, koma ndizovuta kupanga chithandizo champhamvu chamtengo wapatali.Zikuyembekezeka kuti bisphenol A ipitiliza kugwira ntchito pakanthawi kochepa.Ndi kutulutsidwa kwapang'onopang'ono kwa mphamvu zatsopano zopangira, mbali yoperekera imakhala yotayirira, ndipo kupanikizika kwa msika kukadali kwakukulu.
