Kubva Gumiguru 2022, musika webisphenol A wakadzikira zvakanyanya, uye wakaramba wakaora mwoyo mushure meZuva reGore Idzva, zvichiita kuti musika uome kushanduka. Kubva muna Ndira 11, musika weBisphenol A wepamusha wakachinja-chinja, maitiro ekumirira-uye-kuona evatori vechikamu pamusika haana kushanduka, zvakakosha zvemusika zvakachinja zvishoma, manzwiro ekutenga evashandisi aive akangwarira, uye musika wenguva pfupi wakachinja-chinja mune nhete. Kudzikira kwemaitiro kunonyanya kukanganiswa nekupokana pakati pekupa uye kudiwa, uye zvakaoma kutsigira kumusoro nekudzika kweiyo indasitiri cheni.

Kugona kwekugadzira kwebisphenol A kuri kuramba kuchiwedzera, uye kumanikidza kwekupa kuchiripo
Kubva Gumiguru 2022, kuwanikwa kwebisphenol A mudzimba kwakawedzera zvakanyanya, kusanganisira 200000 matani / gore yeLuxi Chemical Group Co., Ltd., 240000 matani / gore reWanhua Chemical Group Co., Ltd., uye 680000 matani / gore reJiangsu Ruiheng New Material Technology Co., Ltd. kukura kwekugadzirwa, uye kuwanikwa kwemukati kwebisphenol A kwakawedzera zvakanyanya. Zvichienzaniswa neavhareji pamwedzi kubuda kwemamiriyoni e1.82 emamiriyoni emunguva yapfuura, kuwanikwa kwese mukota yechina kwakawedzera zvakanyanya.
Muna 2023, China bisphenol A ichine hutsva hwekukura. Zvinonzwisiswa kuti bisphenol A yekugadzira huwandu huchawedzera ne610000 matani muna 2023, kusanganisira 200000 matani / gore yeGuangxi Huayi, 170000 matani / gore yeSouth Asia Plastics, 240000 matani / gore yeWanhua, uye 680000 kota yechina inosvika matani makumi maviri nemaviri. 5.1 miriyoni matani / gore muna 2023, nekuwedzera kwegore-pa-gore kweanenge 38%. Parizvino, hupfumi huri munguva yekudzoreredza, uye kuchine kusavimbika kwakasiyana-siyana muhafu yekutanga yegore, uye kumanikidzwa kwekupa kunokonzerwa nekuenderera mberi kwekuwedzera kwesimba rekugadzira kuripo.
Mitemo yakati wandei yakawedzera musika, uye kudiwa kwekupedzisira kwave kupora zvishoma nezvishoma

Zviitiko zvehutano hweveruzhinji zvichine simba guru mukusimudzira hupfumi hwepamba uye kudzoreredza kwekuda kwemafekitori ekupedzisira, kunyanya muhafu yekutanga ya2023, iyo icharamba iri iyo pfungwa yekudzoreredza musika. Kunyangwe marongero akasiyana akaunzwa kusimudzira musika, kudzoreredza kwezvinodiwa kuchiri kuda nguva yekugaya. Kudzika kwemvura kudiwa uye kushandiswa kuri kudzikira. Kubva muna Mbudzi kusvika kuZuva reGore Idzva, zvizhinji zvezvigadzirwa zvePC zvakagaya zvigadzirwa muzvitoro, uye chinangwa chekutenga chakadzikira. Nekudzikira kwematerminal mirairo, yakadzika epoxy resin uye zvimwe zvigadzirwa zvakarambawo. Zvinoenderana nekutariswa kwemasangano emabhizinesi, iyo liquid epoxy resin muEast China yadzikira ne25% kubva kota yechina, uye zvigadzirwa zvePC zvadzikira ne8%. Mushure meZuva reGore Idzva, kugadzirira kwezvinhu zveindasitiri yemagetsi emhepo yakadzika, asi kushanduka kwemusika hakusi pachena.
Mutengo webisphenol A wakadzikira kupfuura wezvigadzirwa, uye mari yepurofiti yakadzikira
Kubva pabisphenol A industry chain diagram, zvinogona kuonekwa kuti kuderera kwebisphenol A kwakakura kudarika kwepenol mbishi uye acetone, uye purofiti yebisphenol A inoderera. Kunyanya ne rebound yemusika we phenol / acetone muna Zvita, bisphenol A haina kusimuka pasi pekutsigirwa kwemutengo, asi yakaramba yakaora mwoyo pasi pekumanikidzwa kwekupa, uye purofiti yeindasitiri yakapinda mukurasikirwa.
Mumatunhu maviri ari pasi pemvura, kudzikira kwe epoxy resin kwanga kusinganyanyo siyana neayo ezvigadzirwa, ukuwo kudzikira kwezvigadzirwa zvePC kwaive kwakadzikira pane izvo zvekushandisa nekuda kwekukanganisa kwekupa kwavo uye kuda kwavo. Kare, PC yaive mukurasikirwa nekuda kwekukanganisa kwemutengo wepamusoro webisphenol A, uye yakadzika PC yakashanduka kuita purofiti mumwedzi miviri pakupera kwegore, uye purofiti yakakura yeindasitiri yakawedzera. Nekuenderera mberi kuburitswa kwepamusoro-pasi kugona uye purofiti kugoverwa kwebisphenol A indasitiri, kugona kwenode imwe neimwe kuchawedzera zvakanyanya muna 2023. Shanduko dzekugovera uye kudiwa kwedivi uye purofiti pane imwe neimwe node inogona kutariswa.

Kukura kwemusika kuwandisa, BPA pasi pekumanikidzwa mune ramangwana

Sezvo Mutambo weChirimo wava kusvika, kudiwa kwemusika kuri kuita husimbe, misika yenhaurirano yebisphenol A yakanyarara, uye chikamu chinodiwa cheepoxy resin muindasitiri yemagetsi yemhepo yakawedzera zvishoma, asi kukura kuri kuita kushoma pane kuwedzera kwedivi rekupa, izvo zvakaoma kugadzira rutsigiro rwebisphenol A. Kuderera kwese kukwira kwephenol padivi uye kuderera kukuru. Musika wacho wakamira kudonha uye wakawedzera zvakare munguva pfupi yapfuura, asi zvakaoma kuumba yakasimba mutengo rutsigiro. Zvinotarisirwa kuti bisphenol A ichachengetedza mashandiro ekuita munguva pfupi. Nekuburitswa zvishoma nezvishoma kwehunyanzvi hwekugadzira hutsva, rutivi rwekugovera rwakasununguka, uye kudzvanywa kwemusika kuchiri kukuru.
