Imikhiqizo
i-styrene ye-PS
i-styrene ye-PS,
i-styrene ye-Polystyrene, i-styrene esetshenziselwa ukukhiqiza ama-polystyrene resins, i-styrene esetshenziselwa ukukhiqizwa kwe-polystyrene,
I-Polystyrene (PS) i-polymer yokwenziwa eyenziwe ngeketango lama-styrene monomers futhi ihlanganiswe kusuka kumikhiqizo ye-petrochemical.Ifomula yamakhemikhali ye-polystyrene ayizange itholakale ngaphambi kuka-1839, futhi kuzodlula ikhulunyaka ngaphambi kokuba inqubo yayo yokuhlanganisa yenziwe ibe yizimboni.
Yasungulwa ngo-1944, i-polystyrene eyandisiwe (i-PSE noma i-XPS) yaqala ukusetshenziswa njenge-insulator ezakhiweni, ezokwakha, ezokuthutha kanye nembonini yokucubungula ukudla.
Namuhla i-Polystyrene ibalulekile ezizindeni eziningi nasezimbonini.
Impahla yokugcina yale nto: igaywa kabusha kalula ngenqubo ye-granulation.
