Muna 2025, indasitiri ye styrene yakaratidza maitiro ekuti "kudzikira kwekutanga kwozodzoka" pakati pekubatana pakati pekuburitswa kwesimba rakawanda uye kusiyana kwezvinodiwa. Sezvo kumanikidzwa kwechikamu chekugovera kwakadzikira zvishoma, zviratidzo zvekuderera kwemusika zvakava pachena zvakanyanya. Zvisinei, kusawirirana kwechimiro pakati pezvinhu zvakawanda uye kusiyana kwezvinodiwa kwakaramba kusina kugadziriswa, zvichideredza mukana wekudzoka kwemitengo.
Kushomeka kwesimba remagetsi kudivi rekupa ndiro raive chinhu chikuru chainetsa musika muhafu yekutanga yegore. Muna 2025, kugona kwekugadzira styrene itsva munyika kwakatanga kuenderera mberi, uko kugona kwekugadzira styrene itsva kwakawedzera pagore kwakapfuura matani mamiriyoni maviri. Mapurojekiti makuru ekuchenesa nekubatanidza makemikari akadai seLiaoning Baolai neZhejiang Petrochemical akabatsira kuwedzera kukuru, zvichiita kuti kugona kwemagetsi kukure ne18%. Kuburitswa kwesimba remagetsi, pamwe chete nemwaka wekunze kwemwaka wekunze kwemwaka wekutanga, zvakawedzera kusawirirana kwezvinodiwa nevatengi mumusika. Mitengo yestyrene yakaramba ichiderera kubva pa8,200 yuan patani pakutanga kwegore, ichisvika pakaderera pagore re6,800 yuan patani pakupera kwaGumiguru, zvichiratidza kudzikira kwe17% kubva pakutanga kwegore.
Mushure mepakati paMbudzi, musika wakawedzera kukwira zvishoma nezvishoma, nemitengo ichikwira kusvika pa7,200 yuan patani, kuwedzera kweinenge 6%, zvichiratidza kutanga kwekubuda kwehunhu hwekudzika. Kudzoka kwacho kwakakonzereswa nezvinhu zviviri zvikuru. Chekutanga, divi rekugovera rakaderera: mafekitori matatu ane huwandu hwematani miriyoni 1.2 pagore muShandong, Jiangsu nedzimwe nzvimbo dzakamira kushanda kwenguva pfupi nekuda kwekugadzirisa michina kana kurasikirwa nepurofiti, zvichideredza mwero wekushanda kwevhiki nevhiki kubva pa85% kusvika pa78%. Chechipiri, divi rekudhura rakapa rutsigiro: zvichikonzerwa nekukwira kwemitengo yemafuta epasi rose uye kudzikira kwezvikamu zvepachiteshi, mutengo webenzene yekudya wakakwira ne5.2%, zvichikwidza mutengo wekugadzira westyrene. Kunyange zvakadaro, zvinhu zvakawanda zvakaramba zviri chipingamupinyi chikuru. Pakupera kwaMbudzi, zvinhu zvestyrene pachiteshi cheEast China zvakasvika matani 164,200, 23% yakakwira kupfuura nguva imwe chete gore rapfuura. Mazuva ekuchinjana kwezvinhu akagara pamazuva gumi nemaviri, achipfuura zvakanyanya mazuva masere, zvichideredza kuwedzera kwemitengo.
Maitiro akasiyana ekudiwa kwemotokari akawedzera kuoma kwemusika, zvichikonzera "kushanda kwematanho maviri" muzvikamu zvikuru zviri pasi. Indasitiri yeABS (Acrylonitrile-Butadiene-Styrene) yakabuda senzvimbo inonyanya kukosha: ichibatsirwa nekuwedzera kuri kuita kutengeswa kwemotokari itsva dzemagetsi nemidziyo yemumba yakangwara, kudiwa kwayo kwegore negore kwakawedzera ne27.5% gore negore. Vagadziri vakuru veABS vemuno vakaramba vaine mwero wekushanda weanopfuura 90%, zvichiita kuti kudiwa kwestyrene kuve kwakasimba. Kusiyana neizvi, indasitiri yePS (Polystyrene) neEPS (Expandable Polystyrene) dzakatambura nekudiwa kwakaderera, zvichikonzerwa nekusasimba kwenguva refu mumusika wezvivakwa. EPS inonyanya kushandiswa muzvinhu zvekudzivirira madziro ekunze; kudzikira kwe15% pagore mukutanga kwekuvaka dzimba itsva kwakaita kuti varimi veEPS vashande vari pasi pe50%. Panguva imwe chete, varimi vePS vakaona mwero wekushanda kwavo uri pa60%, pasi pehuwandu hwenguva imwe chete gore rapfuura, nekuda kwekuderera kwekukura kweindasitiri dzemwenje dzakadai sekurongedza nematoyi.
Parizvino, musika we styrene uri muchikamu chakaenzana chinoratidzwa ne "kudzikira kwekupa zvinhu zvichipa musiyano wepasi uye kudiwa kunoderedza mukana wekuwedzera". Kunyangwe hunhu hwepasi hwabuda, simba rekudzoka richiri kumirira kubviswa kwezvinhu zvinobudirira uye kudzoreredzwa kwezvinodiwa zvizere. Munguva pfupi, zvichidziviswa nemiganhu yekufambisa zvigadzirwa zvemakemikari munguva yechando uye kutangazve kwemamwe mafekitori ekugadzirisa, musika unotarisirwa kuchinja-chinja. Munguva yepakati nepakati, kutariswa kunofanirwa kupihwa kune kuwedzera kwemhedzisiro yemitemo yezvivakwa yakasununguka pakudiwa kwePS neEPS, pamwe nekuwedzera kwekuda kweABS muchikamu chekugadzira chepamusoro-soro. Zvinhu izvi zvichasarudza pamwe chete kukwirira kwekudzoserwa kwemitengo ye styrene.
