Muna 2023, kuwedzera kwakawedzera kweindasitiri yePC yeChina kwasvika kumagumo, uye indasitiri yakapinda mudenderedzwa rekugaya iripo yekugadzira.Nekuda kweiyo nguva yekuwedzera yekuwedzera yezvigadzirwa zvemhando yepamusoro, purofiti yePC yakaderera yakawedzera zvakanyanya, purofiti yePC indasitiri yakawedzera zvakanyanya, uye chiyero chekushandisa uye kubuda kwesimba rekugadzira mudzimba zvakawedzera zvakanyanya.

Muna 2023, kugadzirwa kwePC yemumba kwakaratidza kukwira kwepamwedzi, kwakakwira zvakanyanya kupfuura nhoroondo yenguva imwe cheteyo.Zvinoenderana nenhamba, kubva muna Ndira kusvika Chivabvu 2023, iyo yakazara kugadzirwa kwePC muChina yaive matani miriyoni 1.05, kuwedzera kweanopfuura 50% zvichienzaniswa nenguva yakafanana gore rapfuura, uye avhareji yehuwandu hwekushandisa yakasvika 68.27%.Pakati pavo, avhareji yekugadzirwa kubva munaKurume kusvika Chivabvu yakapfuura 200000 matani, inova yakapetwa kaviri avhareji yegore muna 2021.
1. Kuwedzera kwepakati kwesimba remumba kwakapera, uye huwandu hutsva hwekugadzira mumakore mashanu anotevera hushoma.
Kubva 2018, China yekugadzira PC yekugadzira yakawedzera nekukurumidza.Kubva pakupera kwa2022, huwandu hwese hwekugadzira PC hwepamba hwakasvika 3.2 miriyoni matani / gore, kuwedzera kwe266% zvichienzaniswa nekupera kwa2017, nekukura kwegore negore kukura kwe30%.Muna 2023, China inongowedzera huwandu hwekugadzira ne160000 matani eWanhua Chemical uye kutangazve kugona kugadzira nematani 70000 pagore muGansu, Hubei.Kubva 2024 kusvika 2027, hutsva hwekugadzira PC yeChina hunotarisirwa kungopfuura matani miriyoni 1.3, nekukura kwakaderera zvakanyanya kupfuura kare.Naizvozvo, mumakore mashanu anotevera, kugaya iripo yekugadzira kugadzirwa, zvishoma nezvishoma kuvandudza kunaka kwechigadzirwa, kupatsanurwa kugadzirwa, kutsiva kunze kwenyika, uye kuwedzera kunze kwenyika kuchava iyo toni huru yeChina PC indasitiri.
2. Raw zvinhu zvakapinda munguva yekuwedzera kwepakati, zvichikonzera kuderera kukuru kwemitengo yeketani yeindasitiri uye kuderera zvishoma nezvishoma mupurofiti.

Zvinoenderana neshanduko mubisphenol A uye maviri makuru ekugadzira dhizaini mumakore mashanu apfuura, mutsauko wekukwira nekudzika kwegomba rekugadzira muna 2022 wakasvika padanho rakaderera mumakore mashanu, pamamirioni 1.93 pagore.Muna 2022, huwandu hwekugadzira bisphenol A, PC, uye epoxy resin ine gore-pa-gore kukura mitengo ye76.6%, 13.07%, uye 16.56%, zvichiteerana, yaive yakaderera mumaindasitiri.Nekuda kwekuwedzera kwakakosha uye kuita pundutso kwebisphenol A, purofiti yePC indasitiri yakawedzera zvakanyanya muna 2023, ichisvika padanho rayo repamusoro mumakore achangopfuura.

Kubva pakuchinja kwepurofiti yePC uye bisphenol A mumakore matatu apfuura, iyo indasitiri cheni purofiti kubva 2021 kusvika 2022 inonyanya kutariswa kumusoro.Kunyangwe PC inewo yakakosha purofiti, muganho wakadzikira zvakanyanya pane wezvigadzirwa;Muna Zvita 2022, mamiriro ezvinhu akachinja zviri pamutemo uye PC yakashandura zviri pamutemo kurasikirwa kuita purofiti, ichipfuura bisphenol A zvakanyanya kekutanga (1402 yuan uye -125 yuan zvichiteerana).Muna 2023, purofiti yeindasitiri yePC yakaramba ichidarika iyo yebisphenol A. Kubva muna Ndira kusvika Chivabvu, avhareji yepurofiti yeaviri yaive 1100 yuan/ton uye -243 yuan/ton, zvichiteerana.Nekudaro, gore rino, iyo yepamusoro yekupedzisira mbishi zvinhu phenol ketone yaivewo mune yakakura kurasikirwa mamiriro, uye PC zviri pamutemo yakashandura kurasikirwa.
Mumakore mashanu anotevera, simba rekugadzira phenolic ketones, bisphenol A, uye epoxy resins richaramba richikura zvakanyanya, uye PC inotarisirwa kuenderera mberi nekuita pundutso seimwe yezvigadzirwa zvishoma mumaketani eindasitiri.
3. Huwandu hwekupinza munyika hwakadzikira zvakanyanya, ukuwo kutengesa kunze kwenyika kwave kuita mabhindauko.

Muna 2023, iyo mambure ekunze ePC yepamba akadzikira zvakanyanya.Kubva muna Ndira kusvika Kubvumbi, huwandu hwese hwekupinza kwePC hwepamba hwaive matani 358400, nehuwandu hwekuwedzera kunze kwenyika hunosvika 126600 matani uye net yekupinda vhoriyamu ye231800 matani, kuderera kwe161200 matani kana 41% zvichienzaniswa nenguva yakafanana gore rapfuura.Nekuda kwekuita / kungoita kubviswa kwezvinhu zvinotengeswa kunze kwenyika uye kukura kwekutengesa kunze kwenyika, kutsiva kwezvinhu zvemumba pakati pevashandisi vepasi kwakawedzera zvakanyanya, izvo zvakakurudzira zvikuru kukura kwekugadzirwa kwePC yepamba gore rino.
Muna Chikumi, nekuda kwekugadzirisa kwakarongwa kwemabhizinesi maviri anopihwa mari kunze kwenyika, kugadzirwa kwePC yemumba kunogona kunge kwakadzikira zvichienzaniswa naMay;Muchikamu chechipiri chegore, zvinhu zvakasvibirira zvekumusoro zvakaramba zvichikanganiswa nekuwedzera kwesimba, zvichiita kuti zvive zvakaoma kuvandudza purofiti, nepo PC yakadzika yakaramba ichiita purofiti.Kutarisana nemamiriro ezvinhu aya, purofiti yakaramba iripo yePC indasitiri inotarisirwa kuenderera.Kunze kwemafekitori makuru ePC ayo achiri akagadzira zvirongwa zvekugadzirisa kubva Nyamavhuvhu kusvika Gunyana, izvo zvichakanganisa kugadzirwa kwemwedzi, kushandiswa kwesimba repamba uye kugadzirwa kucharamba kuri padanho repamusoro kwenguva yasara.Naizvozvo, zvinotarisirwa kuti kugadzirwa kwePC yemumba muhafu yechipiri yegore kucharamba kuchikura kana ichienzaniswa nehafu yekutanga.
