El i-petroleum inezicelo eziningi okunye okusetshenziswe kakhulu ukwenza igwebu i-polystyrene umkhiqizo osetshenziswa kakhulu ezinkulungwaneni zemikhiqizo amashumi eminyaka. Kepha lo mkhiqizo awungcolisi nje kuphela ukwenziwa kwawo kepha ukonakala kwawo kwezemvelo nakho kunzima kakhulu, kudala inqwaba yemfucuza engcolisayo.
Abaphenyi baseCase Western Reserve University benze igwebu le-polystyrene -ngenzeka izingxenye zalo ubisi, ubumba kanye ne-glyceraldehyde.
Le nto inamandla futhi inezici ezifanayo ne-petroleum-based polystyrene. Lo mkhiqizo omusha ungasetshenziselwa ukwahlukanisa, ukupakisha, izikhwama, amathreyi, ifenisha, njll.
I-Polystyrene isempilweni yawo wonke umuntu yansuku zonke ngoba inani lemikhiqizo eliyisebenzisa njengezinto eziluhlaza likhulu kakhulu.
Kubalulekile ukuthi okuphuma kukaphethiloli kuqale ukushintshwa lapho kwenziwa imikhiqizo ehlukahlukene ngoba esikhathini esifushane kuzobe kungenzeki kwezomnotho futhi kungabhekeki kahle emvelweni, ngenxa umthelela wezemvelo elikhiqizayo.
Ngenxa yezakhi ezisetshenziselwe ukudala i-polystyrene ebolayo futhi inqubo elula yokukhiqiza, impela lo mkhiqizo uzobiza kakhulu ngezindleko zawo futhi ungasetshenziselwa ukuthengisa.
Akukaziwa ukuthi kungakhiqizwa nini ngobuningi kepha ngokuqinisekile esikhathini esifushane kuzoba semakethe, ngenxa yezimfanelo ezinhle zalolu daba.
Lezi zintuthuko zikhombisa ukuthi kuyenzeka ukuthi kuyekwe ngokuya ngoyela nangokuphuma kwawo nokuthi ezinye izinto noma izinto ezinobungani bemvelo zingasetshenziselwa izinhlelo ezahlukahlukene.
Ukusebenzisa le nto kuzonciphisa i- ukungcola nenani lemfucuza, ngoba i-polystyrene isetshenziswa emhlabeni wonke nasekusetshenzisweni okuhlukahlukene.
Ukuthuthuka kobuchwepheshe kuyadida kangangokuba uma ucwaningo lwezinto zemvelo lusekelwa, isimo sendawo nezomhlaba wonke sizothuthukiswa kakhulu ngesikhathi esifushane.
