Ukupakishwa kokudlakuyisinyathelo esibalulekile sokuqinisekisa ukuthi ukuthuthwa, ukuthengiswa kanye nokusetshenziswa kwempahla akulinyazwa izimo zemvelo zangaphandle kanye nokwenza ngcono inani lempahla.Ngokuthuthuka okuqhubekayo kwezinga lempilo yezakhamizi, umthelela wezinto empilweni yansuku zonke yezakhamuzi uyakhula, futhi inkinga yokungcoliswa okumhlophe iya ngokuya iba mbi kakhulu.Izinto ze-polymer ezibolile seziphenduke indawo eshisayo ocwaningweni nasekuthuthukisweni kwezinto zokupakisha ukudla.Izinto ze-polymer ezibolayoayidingi indawo ekhethekile noma uchungechunge lwezimo zangaphandle ezifana nokukhanya, ukushisa namanzi enqubweni yokuwohloka.Badinga kuphela ukusebenzisa ama-microorganisms ukukhiqiza ukusabela okuhle kwe-physicochemical futhi ekugcineni bakhiqize i-carbon dioxide.Zonke izinhlobo zezinto ezikhiqizwa ukuwohloka ngeke ziveze noma yikuphi ukungcola futhi zibe usongo oluncane empilweni yomuntu.
I-Biodegradableizinto ze-polymer azidingi indawo ekhethekile noma uchungechunge lwezimo zangaphandle ezifana nokukhanya, ukushisa namanzi ohlelweni lokuwohloka.Badinga kuphela ukusetshenziswaama-microorganismsukukhiqiza ukusabela okuhle kwe-physicochemical futhi ekugcineni ukhiqizei-carbon dioxide.Zonke izinhlobo zezinto ezikhiqizwa ukuwohloka ngeke ziveze noma yikuphi ukungcola futhi zibe usongo oluncane empilweni yomuntu.
Izikhwama zokupakisha ze-biodegradable -izikhwama zekhofinezikhwama zokupakisha ezigaywa kabusha -izikhwama zokupakisha ukudlaikhiqizwe yi-Yantai Meifeng Plastic Packaging Co.
Kunezinhlobo ezintathu eziyinhloko zei-biodegradableizinto ze-polymer.Enye yizinto ze-polymer ezikhiqizwa ama-microorganisms, atholakala ngokuyinhloko ngokuvutshelwa kwe-microbial, futhi emele kakhulu i-polyhydroxybutyrate, enezici ezinhle zokubola kwe-biodegradation.Kodwa-ke, izindleko zokucubungula nokukhiqiza izinto ezinjalo ziphakeme kakhulu, futhi azivamile ukusetshenziswa ekukhiqizeni okuthile.Eyesibili i-synthetic polymer materials.Njengamanje, izinto zokwenziwa ze-polymer ezisetshenziswa kakhulu emakethe yaseChina yi-polyvinyl alcohol ne-polycaprolactone.Phakathi kwazo, i-polycaprolactone isetshenziswa kakhulu ekufakweni kokudla.Okwesithathu yizinto ze-polymer zemvelo.Izinto ezijwayelekile ze-polymer zemvelo zifaka i-cellulose, isitashi, amaprotheni, ne-chitosan njengezinto ze-matrix.Ngemuva kokusetshenziswa isikhathi esithile, izinto ze-polymer zemvelo zingonakaliswa kahle futhi zingabi namphumela endaweni yangaphandle yemvelo.noma yikuphi ukungcola.
I-Biodegradableama-polymers angenye yezinto ezintsha kakhulu emkhakheni wokupakisha.I-biodegradable polymers inezinzuzo zeimithombo ebanzi, ukusebenziseka kabusha, ukuvikelwa kwemvelo futhi akukho ukungcola,kodwa ama-biopolymers anemikhawulo ethile mayelana nokumelana nokushisa, i-oksijeni nezakhiwo zokuvimbela umhwamuko wamanzi, izindleko kanye nezakhiwo zemishini.Ngakho-ke, ucwaningo lwale nto yokupakisha idinga ukujuliswa ngokwengeziwe ukuze kuthuthukiswe impilo yeshalofu, inani lokudla okunomsoco kanye nokuphepha kokudla okubangelwa amagciwane.
Ngenxa yalokhu, ziyanda izinkampani seziqalile ukuthuthukisa ukupakishwa okwenziwe ngezinto ezibolayo, ezihambisana nokuthambekela kwezikhathi nokujwayela izimakethe ezintsha.
