Guud ahaan,polystyrenewaa polymer udgoon synthetic oo laga sameeyay monomer styrene, kaas oo ka soo jeeda benzene iyo ethylene, labadaba batroolka.Polystyrene wuxuu noqon karaa mid adag ama xumbo.Polystyrenewaa heerkulbeeg aan midab lahayn, hufan, kaas oo caadi ahaan loo isticmaalo in lagu sameeyo looxa xumbo ama sabuuradaha dahaarka ah iyo nooc ka mid ah dahaarka dabacsan oo ka kooban kuul yar oo polystyrene ah.Xumbo polystyrenewaa 95-98% hawo.Xumbo polystyrene waa dahaarka kulaylka wanaagsan oo sidaas daraaddeed inta badan waxaa loo isticmaalaa sida dhismaha dahaadhidda alaabta, sida insulate foomamka la taaban karo iyo qaab-dhismeedka dahaaran nidaamka dhismaha guddi.La fidiyay (EPS)iyopolystyrene extruded (XPS)Labaduba waxay ka samaysan yihiin polystyrene, laakiin EPS waxay ka kooban tahay kuulyo balaastiig ah oo yaryar oo la isku daray oo XPS waxay ku bilaabataa wax dhalaalid ah oo lagu cadaadiyo foom oo go'yaal ah.XPS waxaa inta badan loo isticmaalaa sida dahaarka looxa xumbo.
Balaadhan polystyrene (EPS)waa xumbo unug adag oo adag.Codsiyada dhismaha iyo dhismaha waxay ku xisaabtamaan saddex-meelood laba meelood baahida loo qabo polystyrene la balaariyay.Waxa loo isticmaalaa dahaarka (daloosha) gidaarada, saqafyada iyo sagxadaha shubka ah.Sababo la xiriira sifooyinka farsamo sida miisaanka oo hooseeya, qallafsanaanta, iyo qaabayntapolystyrene balaariyaywaxaa loo isticmaali karaa codsiyo kala duwan oo kala duwan, tusaale ahaan saxaarad, saxanno iyo sanduuqyo kalluunka.
Inkasta oo polystyrene la balaariyay iyo kuwa la sii saaray labaduba ay leeyihiin qaab-dhismeedka unug-xiran, haddana waa la daadin karaa molecules-ka biyaha oo looma tixgelin karo xannibaad uumiga.Balaadhinta polystyrene waxaa jira faraqyo isdhexgal ah oo u dhexeeya pellets-cell-la-xiran ee la ballaadhiyay kuwaas oo sameeya shabakad furan oo kanaalo ah oo u dhexeeya pellets-ka xidhan.Haddii biyuhu ay baraf galaan, way balaadhaan oo waxay keeni karaan pellets polystyrene inay ka soo baxaan xumbo.
