Ukuqalisa
Ipulasitiki elinengozi libhekisela kuhlobo lwepulasitiki ahlangabezana nalo izidingo zokusebenzisa, ukusebenza kuhlala kungashintshiwe ngesikhathi sokulondolozwa, futhi kungadilizwa ngezinto ezinobungani bemvelo ngemuva kokusebenzisa. Ngakho-ke, kwaziwa nangokuthi njengepulasitiki enokonakala imvelo.
Kunezinhlobonhlobo zamapulasitiki amasha: Plastics we-PhotodeGradable, iplastiki ye-biodegradable, isithombe / i-oxidation / iplastiji ye-bioderics esekelwe e-bioderics, amapulasitiki asuselwa ku-carboplistic asuselwa ku-starch asele.
Ukuwohloka kwe-polymer kubhekisele kwinqubo yokwephula i-macromolecular chain ye-polymerization ebangelwa izici zamakhemikhali nezibonakalayo. Inqubo yokuwohloka lapho ama-polymers evezwa khona ngezimo zemvelo ezinjenge-oksijini, amanzi, imisebe, amakhemikhali, ukungcola, amabutho emishini, izinambuzane nezinye izilwane, futhi ama-microorganisms abizwa ngokuthi izinambuzane. Ukuwohloka kunciphisa isisindo se-polymer se-polymer futhi kunciphisa izakhiwo ezibonakalayo ze-polymer impahla kuze kube yilapho impahla ye-polymer ilahlekelwa ukusetshenziswa kwayo, into eyaziwa ngokuthi ukuwohloka kokuguga kwezinto ezibonakalayo ze-polymer.
Ukuwohloka kokuguga kwama-polymers kuhlobene ngqo nokuqina kwama-polymers. Ukuwohloka kokuguga kwama-polymers kunciphisa impilo yenkonzo yamapulasitiki.
Kusukela kwasungulwa amapulasitiki, ososayensi baye bazibophezela ekuhlanganeni kwalezi zinto, okungukuthi, isifundo sokuzinza, ukuze ososayensi bakwazi ukuqina ama-polymer, futhi ososayensi emazweni ahlukahlukene basebenzisa nokuziphatha okusokisanayo kwama-polymers.
Izindawo eziphambili zezicelo zamapulasitiki angonakalisiwe yilezi: Ifilimu lezolimo le-Mulch, izinhlobo ezahlukahlukene zezikhwama zokupakisha zepulasitiki, izikhwama zodoti, izikhwama zezitolo ezitolo ezinkulu zezitolo kanye nezitsha zokupheka.
Umqondo wokuwohloka
Inqubo yokucekelwa phansi yemvelo enokonakala imvelo ikakhulukazi ibandakanya i-biodegradation, i-photodegradation kanye nokuwohloka kwamakhemikhali, futhi lezi zinqubo ezintathu eziphambili eziphambili zinemiphumela emibumbene, futhi inemiphumela ehambisanayo. Isibonelo, i-photodegradation kanye nokonakala kwe-oxide kuvame ukuqhubeka ngasikhathi sinye futhi kugqugquzele omunye komunye; I-BiodeGradation kungenzeka ukuthi yenzeke ngemuva kwenqubo ye-PhotoDegradation.
Umkhuba wesikhathi esizayo
Ukufunwa ngopulasitiki ongonakalayo kulindeleke ukuthi kwandiswe njalo, futhi kancane kancane faka iningi lemikhiqizo eyenziwe ngepulasitiki yendabuko.
Kunezizathu ezimbili ezinkulu eziholela kulokhu, 1) Ukwazisa okwandayo komphakathi ekuvikelweni kwemvelo kugqugquzela abantu abaningi abajwayele umkhiqizo we-eco-friendly. 2) Ukuthuthuka ku-Technology ukwehlisa izindleko zokukhiqiza zemikhiqizo yepulasitiki engathandeki. Kodwa-ke, izindleko eziphezulu zama-resins angonakalayo kanye nokuhlala okuqinile kwezimakethe zawo ngamapulasitiki ahlukahlukene asevele ekhona okwenza kube nzima kumapulasithi we-biodegradable ukungena emakethe. Ngakho-ke, ipulasitiki egcwele i-biodegramable ngeke ikwazi ukufaka esikhundleni sepulasitiki yendabuko kumculo omfishane.
Ukuzikhulula: Yonke imininingwane nolwazi olutholwe nge-EcooPro Prometic Co, Ltd kufaka phakathi kepha kungagcini ekufanelekelweni ngokwezinto ezibonakalayo, izakhiwo ezibonakalayo, ezenziwa, izici nezindleko zinikezwa ngenjongo yolwazi kuphela. Akufanele kubhekwe njengokucaciswa okubophayo. Ukuzimisela kokufaneleka kwalolu lwazi nganoma yikuphi ukusetshenziswa okuthile kungumsebenzi womsebenzisi. Ngaphambi kokusebenza nganoma iyiphi impahla, abasebenzisi kufanele baxhumane nabahlinzeki bezinto ezibonakalayo, i-ejensi kahulumeni, noma i-ejensi yesitifiketi ukuze bathole imininingwane ethile, ephelele futhi enemininingwane mayelana nokuqukethwe abakucabangayo. Ingxenye yedatha nolwazi lisakhishwe ngokwakheka ngokusekelwe ezincwadini zentengiso ezinikezwe ngabahlinzeki be-polymer nezinye izingxenye zivela ekuhlolweni kochwepheshe bethu.
