styrene kwa PS,
styrene ya Polystyrene, styrene yomwe imagwiritsidwa ntchito popanga utomoni wa polystyrene, styrene yomwe imagwiritsidwa ntchito popanga polystyrene,
Polystyrene (PS) ndi polima wopangidwa kuchokera ku unyolo wa styrene monomers ndipo amapangidwa kuchokera ku petrochemical byproducts.Mankhwala a polystyrene sanapezeke chaka cha 1839 chisanafike, ndipo zaka zana zidzadutsa kuti kaphatikizidwe kake kapangidwe kake kakhale kopanga mafakitale.
Anapangidwa mu 1944, polystyrene yowonjezera (PSE kapena XPS) idagwiritsidwa ntchito koyamba ngati insulator m'nyumba, zomangamanga, zoyendetsa ndi kukonza chakudya.
Masiku ano polystyrene ndiyofunikira m'magawo ambiri ndi mafakitale.
Chofunikira kwambiri pazachinthu ichi: chimatha kubwezeretsedwanso mosavuta pogwiritsa ntchito granulation.
