Ukusukela ekuqaleni kuka-2020, ubhubhani omtsha wesithsaba ugquba kwihlabathi jikelele kwaye ubenempembelelo kushishino lwePCB yehlabathi. I-China ihlalutya umthamo wedatha wenyanga wokuthumela ngaphandle we-PCB yaseTshayina ekhutshwe nguLawulo Jikelele lweZinto. Ukusukela ngoMatshi ukuya kuNovemba ka-2020, umthamo wokuthunyelwa kwe-PCB waseTshayina ufikelele kwiiseti zeebhiliyoni ezingama-28, ukonyuka konyaka-ngonyaka nge-10.20%, irekhodi eliphezulu kule minyaka ilishumi idlulileyo.
Phakathi kwabo, ukusuka ngoMatshi ukuya ku-Epreli ka-2020, ukuthunyelwa kwe-PCB yaseTshayina kunyuke kakhulu, kunyuke nge-13.06% kunye ne-21.56% unyaka nonyaka. Izizathu zohlalutyo: phantsi kweempembelelo zobhubhani ekuqaleni kuka-2020, izinga lokusebenza kweefektri zePCB zaseTshayina kwilizwe laseTshayina, ukuthunyelwa kwakhona emva kokuqaliswa komsebenzi, kunye nokugcinwa kwakhona kwemizi-mveliso yaphesheya kweelwandle .
Ukususela ngoJulayi ukuya kuNovemba ka-2020, ukuthunyelwa kwe-PCB yaseTshayina kunyuke kakhulu unyaka nonyaka, ngakumbi ngo-Okthobha, okunyuke nge-35.79% unyaka nonyaka. Oku kunokubangwa ikakhulu kukufumana kwakhona amashishini asezantsi kunye nokwanda kwemfuno yeefektri zePCB zaphesheya. Phantsi kobhubhane, umthamo wobonelelo lweefektri zePCB zaphesheya azizinzanga. Iinkampani zaseTshayina ezikuMainland zenza iiodolo zokuTshintshela kumazwe aphesheya.
Ngokutsho kwedatha yePrismark, ukusuka kwi-2016 ukuya ku-2021, izinga lokukhula kwexabiso lemveliso yecandelo ngalinye leshishini lePCB yaseTshayina liphezulu kunomndilili wehlabathi, ngakumbi kumxholo wobuchwephesha obufana neebhodi eziphezulu, iibhodi ze-HDI, iibhodi eziguquguqukayo. kunye nokupakisha substrates. PCB. Thatha i-package substrates njengomzekelo. Ukusukela ngowama-2016 ukuya kowama-2021, ixabiso lemveliso yelizwe lam lokupakisha lilindeleke ukuba likhule ngesantya esihlanganisiweyo sonyaka sokukhula esimalunga ne-3.55%, ngelixa i-avareji yehlabathi iyi-0.14% kuphela. Umkhwa wokudluliselwa kwamashishini ucacile. Ubhubhane kulindeleke ukuba lukhawulezise ukudluliselwa kweshishini le-PCB e-China, kunye nokudluliselwa Yinkqubo eqhubekayo.
