El petroleum Izicelo ezininzi enye yezona zisetyenzisiweyo kukwenza amagwebu IPolystyrene imveliso esetyenziswa ngokubanzi kumawaka eemveliso kumashumi eminyaka. Kodwa le mveliso ayingcolisi kuphela ukwenziwa kwayo kodwa ukonakaliswa kwayo kwendalo esingqongileyo nako kunzima kakhulu, kuvelisa isixa esikhulu senkunkuma engcolisayo.
Abaphandi abavela kwiYunivesithi yase-Case Western Reserve benze i-polystyrene foam biodegradable ezinamacandelo obisi, udongwe kunye neglyceraldehyde.
Ezi zinto zomelele kwaye zineempawu ezifanayo ne-petroleum-based polystyrene. Le mveliso intsha inokusetyenziselwa ukugquma, ukupakisha, iibhegi, iitreyi, ifanitshala, njl.
IPolystyrene kubomi bemihla ngemihla bomntu wonke kuba inani leemveliso ezizisebenzisayo njengezinto ezingafunekiyo zinkulu.
Kubalulekile ukuba iziphumo ze-petroleum ziqale ukutshintshwa ekwenziweni kweemveliso ezahlukeneyo kuba ngexeshana elifutshane kuya kuba yinto engenakwenzeka kwezoqoqosho kunye nokungahoywa kwendalo, ngenxa mpe mbelelo ukuba ivelisa.
Ngenxa yezinto ezazisetyenziselwa ukwenza i-polystyrene enokuboliswa yintsholongwane kunye nenkqubo elula yokuvelisa, ngokuqinisekileyo le mveliso iya kufikeleleka kakhulu ngexabiso layo kwaye inokusetyenziselwa urhwebo.
Akukaziwa ukuba inokuveliswa nini kodwa ngokuqinisekileyo ngexeshana elincinci iya kuba kwintengiso, ngenxa yeempawu ezintle zeli nqaku.
Olu phuhliso lubonisa ukuba kunokwenzeka ukuyeka ngokuxhomekeke kwioyile nakwizinto eziphuma kuyo kwaye ezinye izinto ezinobungozi kokusingqongileyo okanye izinto zinokusetyenziselwa usetyenziso olwahlukeneyo.
Sebenzisa le nto kuya kunciphisa Ungcoliseko kunye nobungakanani benkunkuma, kuba i-polystyrene isetyenziswa kwihlabathi liphela kunye nokusetyenziswa ngeendlela ezahlukeneyo.
Ukuqhubela phambili kwetekhnoloji kuyothusa kangangokuba ukuba uphando lwezixhobo zendalo luyaxhaswa, imeko yengingqi kunye nehlabathi iya kuphuculwa kakhulu ngexesha elifutshane.
