Ngo-2023, ukwanda okugxilisiweyo kweShishini lePC yaseTshayina kufike esiphelweni, kwaye ishishini lingenise umjikelo wokugaya umthamo okhoyo wokuvelisa. Ngenxa yexesha lokwandiswa okuphakathi kweendawo eziphakamileyo, inzuzo ye-PC ephezulu ye-PC iye yanda kakhulu, ingeniso yomzi-mveliso wePC sele iphucule kakhulu, kwaye ireyithi yokusetyenziswa kunye nemveliso yemveliso yasekhaya ikwanda kakhulu.

Ngo-2023, imveliso ye-PC yasekhaya ibonakalise imeko yenyanga nenyanga, ingaphezulu kakhulu kunenqanaba lembali ngexesha elinye. Ngokweenkcukacha-mali, ukusuka kuJanuwari ukuya kwi-2023, ukuveliswa kwePC eTshayina yayimalunga ne-1.05 yezigidi, ukunyuka kwexabiso lokusetyenziswa komgangatho elidlulileyo, kwaye umyinge ophakathi usebenzisa i-68.27%. Phakathi kwazo, ukuveliswa komndilili ukusuka ku-Matshi ukuya kudlula iitoni ezingama-200000 eziphindwe kabini kwinqanaba le-avareji ngonyaka we-2021.
1. Ukwanda okuphakathi komthamo wasekhaya kuye kwaphela, kwaye isikhundla esitsha semveliso kule minyaka mihlanu izayo silinganiselwe.
Ukusukela ngo-2018, amandla e-CHC ye-China eChina akhule ngokukhawuleza. Ukugqibela kwe-2022, i-PC iyonke i-PC yemveliso ye-TIT ifikelele kwiitoni ezi-3.2 ezigidi, ukunyuka kwe-266% ithelekiswa nokuphela konyaka ka-2017, kunye nenqanaba lokukhula minyaka le le-30%. Ngo-2023, i-China iya kukhulisa kuphela imigangatho yemveliso nge-160000 yeetoni ze-wahuua kwaye iqale ngokutsha kwemveliso yeetoni ezingama-70000 ngonyaka kwi-Gansu, eHubei. Ukususela ngo-2024 ukuya kwi-2027, i-China entsha ye-China i-China kulindeleke ukuba igqithe kuphela i-1.3 yezigidi zeetoni, ngomgangatho ophantsi wokukhula kunexesha elidlulileyo. Ke ngoko, kule minyaka mihlanu izayo, ukugayisela amandla endalo, ukuphuculwa ngokuthe chu umgangatho wemveliso, ukuveliswa kwemveliso, ukuvelisa okungeneyo, nokutshintsha impahla yokungenisa impahla ye-PC ye-China yePC yaseTshayina.
2. Izinto ezingafunekiyo zingenise ixesha lokwandiswa komhlaba, okukhokelela ekunciphiseni okubonakalayo kwiindleko zekhonkco lokusasaza kunye nokwehla kancinci kwenzuzo.

Ngokutsho kotshintsho kwi-bisphenol ye-bisphenol ephambili kule minyaka mihlanu idlulileyo, umahluko kwimveliso ephantsi ye-2022 ifikelele kwinqanaba eliphantsi kwiminyaka emihlanu, kwiitoni ezizigidi ezili-1.93 ngonyaka. Ngowama-2022, amandla okuvelisa e-Bisphenol A, i-PC, kunye ne-Epoxy Retin ngamanqanaba okukhula kweminyaka engama-76.6%, 13.07%, kunye ne-16.50%, ngeyona ndlela iphantsi, ngeyona ndlela iphantsi. Ngenxa yokwandiswa okubalulekileyo kunye nenzuzo ye-bisphenol a, ingeniso yomzi-mveliso wePC iye yanda kakhulu ngo-2023, ifikelela kwinqanaba layo elililo kule minyaka idlulileyo.

Kwinguqu yenzuzo yePC kunye ne-bisphenol A kule minyaka mithathu idlulileyo, ishishini lokufumana inzuzo ukusuka kwi-2021 ukuya kwi-2022 ijolise ikakhulu kwisiphelo esingaphezulu. Nangona iPC ikwanazo inzuzo equkeni, umda uye waphanga kude kakhulu kunezinto eziluhlaza; NgoDisemba 2022, imeko ibuyiselwe ngokusemthethweni ne-PC iguqule ilahleko kwinzuzo, i-bisphenol egqithileyo iqale (i-1402 yuan kunye -125 yuan). Ngo-2023, ingeniso yeshishini lePC iqhubeke idlula i-bisphenol A. Ukususela ngoJanuwari ukuya kuthi ga kwi-1100 yuan / i-Yuan / Ton kunye ne-124 yuan / ngetoni, ngokulandelelana. Nangona kunjalo, kulo nyaka, isiphelo esingaphezulu se-phenol ketom satoli sasikwindawo ebalulekileyo yelahleko, kwaye i-PC iguqule ilahleko ngokusemthethweni.
Kule minyaka mihlanu izayo, amandla okuvelisa amatophe, i-bisphenol a, kunye ne-Epongqi iya kuqhubeka nokwandisa kakhulu, kwaye i-PC kulindeleke ukuba iqhubeke ukuba yinzuzo njengenye yeemveliso ezimbalwa kwishishini.
3. Imowudi yokungenisa elizweni inciphile kakhulu, ngelixa kuthunyelwa kwelinye ilizwe yenze ezinye iinyawo.

Ngo-2023, ukungenisa i-PH ye-PC yasekhaya kuyatya kakhulu. Ukususela ngoJanuwari ukuya ku-Epreli, ivolumu yokungenisa elizweni i-PH yayiyiitoni ezingama-358400, ngomthamo wokungenisa ngaphandle kwe-126600, ukunciphisa iitoni ezili-161200 okanye i-41% xa kuthelekiswa nexesha elifanayo kunyaka ophelileyo. Enkosi ngokurhoxiswa kwezinto ezingeniswayo ezingeniswe ngaphakathi
NgoJuni, ngenxa yolondolozo olucwangcisiweyo lwamashishini amabini afumana inkxaso-mali, imveliso yePC yasekhaya inokuthi inciphise itekishiwe kuMeyi; Kwisiqingatha sesibini sonyaka, izinto ezingafunekiyo eziqhubekayo ziyachaphazeleka kukwanda kwamandla, kusenza kube nzima ukuphucula iinzuzo, ngelixa ezantsi i-PP iqhubekile nokwenza inzuzo. Ngokuchasene nale mboleko ngasemva, ingeniso egciniweyo yamashishini ePC kulindeleke ukuba iqhubeke. Ngaphandle kwemveliso enkulu yePC esenze izicwangciso zesondlo ukusuka ngo-Agasti ukuya kuSeptemba ukuya kuSeptemba, eziya kuthi zichaphazele imveliso yenyanga, enokuchaphazela umthamo wenyanga, ukusetyenziswa komthamo wasekhaya kunye nemveliso iya kuhlala ikwinqanaba eliphezulu. Ke ngoko, kulindeleke ukuba imveliso ye-PC yendawo kwisiqingatha sesibini sonyaka siza kuqhubeka nokukhula xa kuthelekiswa nesiqingatha sokuqala.
