Umahluko phakathi kweeplastiki ezonakaliswayo kunye neeplastiki ezingonakali

Ekuqaleni kokuvalwa kweplastiki, kufuneka kubekho abantwana abaninzi abazibuza ukuba yintoni iplastiki enokubola.Uthini umahluko phakathi kweeplastiki ezingonakali kunye neeplastiki ezingonakali?Kutheni sisebenzisa i-biodegradableimveliso yeplastiki?zeziphi iingenelo zeeplastiki ezinokubola?Masijonge iinkcukacha.

Iiplastiki ezichithwayo zibhekisela kuhlobo lweeplastiki ezinokuthi zihlangabezane neemfuno zokusetyenziswa kwaye zihlale zingatshintshi ngexesha leshelufu, kodwa zinokutshatyalaliswa kwizinto ezingenabungozi kwindalo phantsi kweemeko zendalo zendalo emva kokusetyenziswa.Ke ngoko, ziiplastiki ezonakaliswa kokusingqongileyo.

Okwangoku, kukho iintlobo ezininzi ezintsha zeplastiki: iiplastiki ezinokuguquguquka, iiplastiki ezinomfanekiso, ukukhanya, i-oxidation / iplastiki enokubola, i-carbon dioxide-based biodegradable plastics, i-thermoplastic starch resin esonakalayo.Iingxowa zeplastiki ezonakaliswayo (oko kukuthi, iingxowa zeplastiki ezisingqongileyo) zenziwe ngezinto zepolymer ezifanaI-PLA,PHAs,PA,PBS.Ingxowa yeplastiki yesiNtu engonakaliyo yenziwe ngeplastiki yePE.

Izinto eziluncedo kwiiplastiki ezonakeleyo:
Xa kuthelekiswa neeplastiki "zenkunkuma emhlophe" ezinokunyamalala amakhulu eminyaka, phantsi kweemeko zomgquba, iimveliso ezihlanjululwe ngokupheleleyo ziyakwazi ukuchithwa ngaphezu kwe-90% ye-microorganisms ngaphakathi kweentsuku ze-30 kwaye ingene kwindalo ngendlela ye-carbon dioxide kunye namanzi.Phantsi kweemeko zokungafaki umgquba, indawo engacocwanga yemveliso enokubola ngokupheleleyo kwindawo yokucocwa kwenkunkuma iya kuthotywa kancinci kancinci kwiminyaka emi-2.
Izingxobo zeplastiki ezonakeleyo zinokubola kwisithuba sonyaka, ngelixa ukhuseleko lokusingqongileyo lweOlimpikiiingqayi zeplastikiinokuqala ukubola kwiintsuku ezingama-72 emva kokulahlwa.Izingxobo zeplastiki ezingonakaliyo zithatha iminyaka engama-200 ukuthotywa.

Kukho iindlela ezimbini eziphambili zokusetyenziswa kweeplastiki ezonakeleyo:

Enye yintsimi apho iiplastiki eziqhelekileyo zazisetyenziswa ekuqaleni.Kule mimandla, ubunzima bokuqokelela iimveliso zeplastiki emva kokusetyenziswa okanye ukusetyenziswa kunokubangela ingozi kwindalo, njengefilimu yeplastiki yezolimo kunye nokupakishwa kweplastiki elahlayo.
Okwesibini yintsimi yokutshintsha ezinye izinto ngeplastiki.Ukusetyenziswa kweeplastiki ezinokonakala kwezi ndawo kunokuzisa lula, njengezikhonkwane zebhola zegalufa kunye nezixhobo zokulungiswa kwezithole kumahlathi ashinyeneyo.

Ngeevenkile ezinkulu, ukuthathwa, ukutya kunye nezinye iindawo ziye zasabela kwizithintelo zeplastiki, zikhuthaza ngenkuthalo ukusetyenziswa kweemveliso zeplastiki ezinokuguquguquka, umahluko phakathi kweeplastiki ezinokonakala kunye neeplastiki ezingonakali kunye neenzuzo zeeplastiki ezonakalisayo nazo zinikezelwa kumntu wonke.
Okwangoku, izinto ezininzi ezithatha indawo yeemveliso zeplastiki zisahlolwa.
