NgoJanuwari 2023, ngenxa “yolindelo oluqinileyo” kunye nokugcinwa nokulibaziseka kothotho lwezixhobo zasekhaya, i-spot end, nangona imfuno iphantsi, kodwa ixabiso lemarike liqinile nje. Emva koMnyhadala weNtwasahlobo, i-spot end ayiphucukanga, kwaye imakethi ye-styrene yasekhaya ibuthathaka kwaye ayiguquguquki. Emva kweholide ye-May Day, imakethi ye-styrene yasekhaya yaphinda yabuthathaka emva kokungavisisani, yaza yawa ngaphantsi kwe-“8″ thousand mark phakathi kuMeyi, yaza yaqhubeka nokuhla. Imakethi ye-styrene yaseMpuma China ukusukela ekuqaleni konyaka i-8400 yuan/ton, yehla ukuya kwi-7360 yuan/ton yangoku, ukwehla kwe-12.38%.

Ukususela ekuqaleni kuka-2023, isiphelo sexabiso le-styrene kunye nezinto ezikrwada ze-benzene ecocekileyo sibonise umkhwa "wokuqala ububanzi kunye nomxinwa", umahluko ophakathi wamaxabiso phakathi kwe-styrene kunye ne-benzene ecocekileyo yayiyi-1349 yuan/ton, ukwanda kwe-17.20% kwixesha elifanayo kunyaka ophelileyo, kwaye inzuzo ephakathi yezixhobo ezingadibaniyo ze-styrene yayimalunga ne--28 yuan/ton, ukunyuka okuhambelanayo kwe-92.86% kwixesha elifanayo kunyaka ophelileyo. Nangona ixabiso le-styrene kunye ne-benzene ecocekileyo ngo-2023 lehle ngokulinganayo xa lithelekiswa nexesha elifanayo kunyaka ophelileyo, kodwa inxalenye yonyaka isicwangciso sokufaka i-styrene, ukugcinwa kwangaphandle kuxhaphake ngakumbi, inqanaba lemarike labonakala "ukubonelela kunye nokulingana okuqinileyo", kwaye kwicala lezinto ezikrwada ze-benzene ecocekileyo kukho ingcamango "yenzuzo ephezulu", umahluko wamaxabiso phakathi kwezi zimbini ukwinqanaba eliphezulu. Phantsi komjikelo omkhulu wemveliso ye-styrene, ukungqubana phakathi kokunikezelwa kunye nemfuno kuyaqhubeka nokwanda, kwaye inzuzo yezixhobo ezingadibaniyo ze-styrene iyaqhubeka nokulungiswa, isiphelo sezinto eziluhlaza asinakunika inkxaso enamandla ye-styrene.

Ukuphikisana phakathi kokunikezelwa kunye nemfuno kuyaqina: i-styrene iyanda ngokukhawuleza, kwaye imfuno incinci.

Kwixesha elifutshane, i-styrene kwikota yesithathu isekwinqanaba lokwanda okukhulu kwamandla kunye nemveliso, kwaye idatha ibonisa ukuba ukwanda okutsha kwesixhobo esisecaleni lobonelelo kuya kuba kukhulu kunokwanda okutsha kwesixhobo esisecaleni lokufuna. Okwangoku, umbono weendaba oqhelekileyo, i-styrene kunye nokwehla kwisiqingatha sesibini sonyaka, nangona kuchatshazelwa lutshintsho kwimveliso kunye nengeniso yentengiso, iiseti ezininzi zezixhobo ziya kulibaziseka, zibonelela ngezinto eziguquguqukayo ezinkulu zokunyuka kobonelelo kunye nemfuno ye-styrene, kodwa xa izixhobo ezintsha zifakwa kwimveliso, kulindeleke ukuba unikezelo olunyukayo lwe-styrene kwikota yesithathu, kwaye unikezelo kunye nemfuno kwimarike kwixesha lobushushu eliphezulu ngoJulayi nango-Agasti zibuthathaka. Imarike yawugaya ngokukhawuleza ukwanda kwaye yalungisa ulwakhiwo lonikezelo kunye nemfuno emva kokuba isixhobo esitsha singene kwimarike, sibekwe ngaphezulu ukuze kuthintelwe ubushushu obuphezulu ngaphandle kwexesha, kwaye imakethi yawa. Ngo-Agasti okanye ekuqaleni kokunyuka, ixesha lokuvelisa lemveli elithi "gold nine silver ten" liyaqhubeka nokubonelela imakethi ngesithuba sokunyuka kwamaxabiso, ngokubanzi, kwikota yesithathu yemarike yasekhaya yestyrene okanye "kwindlela ebuthathaka emva kwemkhwa onamandla", imakethi yestyrene isasekelwe kwixabiso kunye nokubonelela kunye nemfuno yemigca emibini ephambili yempembelelo.
