Polystyrene (PS) yog cov khoom siv hluavtaws ua los ntawm cov saw hlau ntawm styrene monomers thiab yog cov khoom sib txuas los ntawm cov khoom siv petrochemical.Cov qauv tshuaj polystyrene tsis tau pom ua ntej xyoo 1839, thiab ib puas xyoo yuav dhau mus ua ntej nws cov txheej txheem synthesis tuaj yeem ua lag luam.
Tsim nyob rau xyoo 1944, nthuav dav polystyrene (PSE lossis XPS) yog thawj zaug siv los ua cov rwb thaiv tsev hauv tsev, kev tsim kho, kev thauj mus los thiab kev lag luam ua zaub mov.
Niaj hnub no Polystyrene yog qhov tseem ceeb hauv ntau qhov chaw thiab kev lag luam.
Cov cuab yeej cuab tam kawg ntawm cov khoom siv no: nws tau yooj yim rov ua dua los ntawm cov txheej txheem granulation.
