Ukupakishwa kokudlaIsilinganiso esibalulekile sokuqinisekisa ukuthi izinto zokuhamba, ukuthengisa nokusebenzisa impahla azinakaliswa yizimo zangaphandle zemvelo futhi zithuthukise inani lezimpahla. Ngokuthuthuka okuqhubekayo kwekhwalithi yempilo yabahlali, umthelela wezinto ezenzeka empilweni yansuku zonke yabahlali uyanda, futhi inkinga yokungcoliswa okumhlophe iya ngokuya imbi kakhulu. Izinto ze-polyrhradable polymer ziye zaba yindawo eshisayo ocwaningweni nasekuthuthukisweni kwezinto zokupakisha zokudla.Izinto ze-biodegradable polymerAwudingi indawo ekhethekile noma uchungechunge lwezimo zangaphandle ezinjengokukhanya, ukushisa namanzi kwinqubo yokucekelwa phansi. Badinga kuphela ukusebenzisa ama-microorganisms ukukhiqiza ukusabela okuhle kwe-physicochemical futhi ekugcineni bakhiqize i-carbon dioxide. Zonke izinhlobo zezinto ezikhiqizwe ukusabela kokucekelwa phansi ngeke zikhiqize ukungcoliswa komhlaba futhi zibeke usongo oluncane empilweni yabantu.
BiodegradableIzinto ze-polymer azidingi imvelo ekhethekile noma uchungechunge lwezimo zangaphandle ezinjengokukhanya, ukushisa namanzi kwinqubo yokucekelwa phansi. Badinga nje ukusebenzisaama-microorganismsukukhiqiza ukusabela okuhle kwe-physicochemical futhi ekugcineni ukhiqizeI-Carbon Dioxide. Zonke izinhlobo zezinto ezikhiqizwe ukusabela kokucekelwa phansi ngeke zikhiqize ukungcoliswa komhlaba futhi zibeke usongo oluncane empilweni yabantu.
Izikhwama zokupakisha ezingathandeki -Izikhwama zekhofikanye nezikhwama zokufaka kabusha kabusha -Izikhwama zokupakisha zokudlaKukhiqizwe yi-Yantai Meifeng Plastic Packaging Co
Kunezinhlobo ezintathu eziphambili zebiodegradableizinto ze-polymer. Enye yezinto ezisetshenziswayo ze-polymer ezikhiqizwe ama-microorganisms, atholakala ikakhulu ukuvutshelwa kwe-microbial, futhi okumele kakhulu yi-polyhydroxybaterate, enezindawo ezinhle ze-biodegradation. Kodwa-ke, izindleko zokulungisa nezikhiqizwa kwezinto ezinjalo ziphakeme kakhulu, futhi azivamile ukusetshenziswa emkhiqizweni othile. Okwesibili izinto zokwenziwa polymer. Njengamanje, izinto ezisetshenziswa kakhulu ze-polymer ezimakethe zaseChina ziyi-polyvinyl alcohol ne-polycapropactone. Phakathi kwazo, i-polycaproractone isetshenziswa kabanzi ekuphaketheni ukudla. Okwesithathu izinto zemvelo ze-polymer. Izinto ze-polymer ezijwayelekile zifaka i-cellulose, isitashi, amaprotheni, ne-chitosan njengezinto zokwenziwa ze-matrix. Ngemuva kokusebenzisa isikhathi esithile, izinto zemvelo ze-polymer zingadilizwa kahle futhi awunamthelela endaweni yemvelo yangaphandle. noma yikuphi ukungcoliswa.
BiodegradableAma-polymers angenye yezinto ezintsha kakhulu ensimini yokufaka. Ama-polymers angama-bioderhradable anezinzuzo zeImithombo ebanzi, ukutholwa kabusha, ukuvikelwa kwemvelo futhi akukho ukungcoliswa,Kepha ama-biopolymers anokulinganiselwa okuthile ngokuya ngokumelana nokushisa, umoya-mpilo kanye namanzi okuvila izithiyo zamanzi, izindleko kanye nezakhiwo zemishini. Ngakho-ke, ucwaningo lwale nto yokufaka impahla ludinga ukujula ukuze kuthuthukiswe impilo yeshelufu, inani lokudla okunempilo kanye nokuphepha kwe-microbial kokudla.
Ngenxa yalokhu, izinkampani eziningi ngokwengeziwe seziqalile ukuthuthukisa ukufakwa okwenziwe ngezinto ezibonakalayo, zihambisana nomkhuba wezikhathi futhi zivumelanise nezimakethe ezintsha.
