Njengamanje izinto eziwohlokayo ezaziwa kakhulu ziyiI-PLAkanye ne-PBAT, zombili ezingaboli ngokugcwele.
Amapulasitiki angawohlokabhekisela ekilasini lamapulasitiki imikhiqizo yawo engahlangabezana nezidingo zokusetshenziswa ngokwemibandela yokusebenza, ihlale ingashintshile phakathi nesikhathi sokugcinwa, futhi ingacekelwa phansi ibe izinto ezingenabungozi emvelweni ngaphansi kwezimo zemvelo zemvelo ngemva kokusetshenziswa.Ngakho-ke, kubizwa nangokuthi ipulasitiki eyonakaliswa imvelo.
Kunezinhlobonhlobo zezinhlobo ezintsha zamapulastiki: amapulasitiki angaboleka izithombe, amapulasitiki angaboli,ukukhanya/i-oxidation/amapulasitiki awonakaliswa ngokwebhayoloji ngokuphelele, amapulasitiki angaboli asuselwa ku-carbon dioxide, kanye namapulasitiki awonakaliswa yisitashi se-thermoplastic.
Ukuwohloka kwe-polymer kubhekisela enqubweni yokuphula amaketanga e-macromolecular e-polymerized ngenxa yezinto zamakhemikhali nezomzimba.Inqubo yokuwohloka kwe-macromolecular chain breakage yama-polymers evezwe umoya-mpilo, amanzi, imisebe, amakhemikhali, ukungcola, amandla emishini, izinambuzane nezinye izilwane kanye nama-microorganisms kubizwa ngokuthi ukucekelwa phansi kwemvelo.
Ukuwohloka kunciphisa isisindo samangqamuzana e-polymer, futhi izakhiwo ezibonakalayo ze-polymer material ziyancipha kuze kube yilapho into ye-polymer ilahlekelwa ukusebenziseka kwayo.Lesi simo sibizwa nangokuthi ukuwohloka kokuguga kwezinto ze-polymer.
Ukuwohloka kokuguga kwama-polymers kuhlobene ngokuqondile nokuzinza kwama-polymers.Ukuwohloka kokuguga kwama-polymers kunciphisa impilo yesevisi yamapulasitiki.Ngenxa yalesi sizathu, kusukela ekufikeni kwamapulasitiki, ososayensi baye bazinikela ocwaningweni lokulwa nokuguga kwezinto ezinjalo, okungukuthi, ukuzinza, ukuze kukhiqizwe izinto eziqinile ze-polymer, futhi ososayensi abavela emazweni ahlukahlukene basebenzisa. ukuziphatha kokuguga kwe-polymers.Umjaho wokuthuthukisa amapulasitiki awonakaliswa imvelo.
Izinkambu eziyinhloko zokusetshenziswa kwamapulasitiki awonakele yilezi: ifilimu ye-mulch yezolimo, pizikhwama zokupakisha ze-lastic,izikhwama zikadoti, izikhwama zokuthenga ezitolo ezinkulu kanye ne-tableware elahlayo, njll.
