Li Guodong, mokambi molandi ya Departema ya biloko ya chimique biologique ya East China Branch ya Sinopec Chemicals Sales Co., LTD{1}}, alobaki ete biloko ya styrène ebengami banda kala "biloko ya zabolo", mingi mingi mpo na makoki ya bokeli ya moke ya styrène ya ndako liboso ya 2018, oyo ekoki kokokisa te bamposa ya{3}} ya biloko ya mboka na yango ya monene ya 4 ya ba oyo ya zando ya mboka na yango ya monene ya 4*} 2018, volume ya boyei na mboka ekiti mbula na mbula, mpe bozangi bondimi ya boyei na mboka na 2018 ekitisami na 26%.
Na oyo etali makoki ya bokeli, kobanda 2014 kino 2018, makoki ya bokeli ya styrène ya mboka emati uta 6.95 millions ya ba tonnes kino 9.21 millions ya ba tonnes, mpe makoki emati na 32,5%. Na oyo etali consommation apparente, consommation apparente interne na 2014 ezalaki 8,42 millions ya ba tonnes, mpe na 2018 emati na 2,6 millions ya tonnes na 11,02 millions ya ba tonnes, bomati ya 30,9%. Bokoli ya makoki ya bokeli mpe bomeli ezali na tina moko, pe taux ya exploitation emati mbula na mbula, uta 67,48% na 2014 kino 88,06% na 2018.
Li Guodong akotisaki, na oyo etali ba tendances ya ba prix, na kotalaka zando ya Jiangsu Styrene na mibu mitano oyo eleki, intervalle ya fonctionnement ya prix na 2014 ezalaki 6400-12100 Yuan / Ton, 2015 6600-11200 Yuan / Ton, 2016 7700-10900 Yuan / Ton, 2017 8180 - 12,{{5} TON / TON, 4 TON, 4.{6}, 4 TON, 8.{6}, 4 TON, 8.{6}, 4 TON, 8.{6}, 4 TON, 8.{6}, 8.{6}, 8.{6}, 8.{6}, 4.{6},{6} TOnne Tendances ya prix ya styrène na kati ya ndako ezali na boyokani, mpe styrène ezali na corrélation makasi na matière première principale phényl.
For the supply and demand of domestic styrene in 2019-2023, Li Guodong made a prediction.
