Ukwethulwa kwempahla eluhlaza yepulasitiki ebolayo
Itemu elithi “Amapulastiki e-Biodegradable” libhekisela ohlotsheni lwepulasitiki olungahlangabezana nezidingo zokusetshenziswa nokugcina izakhiwo zalo phakathi nesikhathi sokuphila kwalo, kodwa lungehliswa lube yizinto ezingavumelani nemvelo ngemva kokusetshenziswa ngaphansi kwezimo zemvelo zemvelo.Ngokuthuthukisa ukukhetha kwezinto ezingavuthiwe kanye nenqubo yokukhiqiza, ipulasitiki ye-Biodegradable ingabola kancane kancane ibe yizicucu futhi ekugcineni ibole ngokuphelele ngaphansi kwesenzo esihlangene sokukhanya kwelanga, imvula kanye nama-microorganisms izinsuku ezimbalwa noma izinyanga.
Izinzuzo zepulasitiki ebolayo
Ngesikhathi sesenzo somhlaba “sokuvinjelwa kwepulasitiki” futhi sibhekene nesimo sokuqwashisa ngemvelo okuthuthukisiwe, ipulasitiki ebolayo ibonwa njengethatha indawo yepulasitiki esetshenziswayo evamile.Ipulasitiki ye-Biodegradable ibola kalula ngenxa yemvelo yemvelo kunepulasitiki ye-polymer evamile, futhi iyasebenza kakhulu, yonakala futhi iphephile.Ngisho noma ipulasitiki ye-Biodegradable ingena endaweni yemvelo ngengozi, ngeke idale umonakalo omkhulu futhi ingasiza ngokungaqondile ukuqoqa udoti wezinto eziphilayo ngenkathi inciphisa umthelela wemfucuza yezinto eziphilayo ekubuyiseleni udoti wepulasitiki ngomshini.
Ipulasitiki ye-Biodegradable inezinzuzo zayo ekusebenzeni, ukusebenziseka, ukuwohloka nokuphepha.Mayelana nokusebenza, ipulasitiki ye-Biodegradable ingafinyelela noma yedlule ukusebenza kwamapulasitiki endabuko emikhakheni ethile.Ngenkathi ngokuya kokusebenziseka, ipulasitiki ebolayo inezinto ezifanayo zokusebenza kanye nezindawo zokuhlanzeka kumapulasitiki endabuko afanayo.Mayelana nokonakaliswa, ipulasitiki ebolayo ingonakaliswa ngokushesha endaweni yemvelo (ama-microorganisms athile, izinga lokushisa kanye nomswakama) ngemva kokusebenzisa futhi ibe yimfucumfucu esebenziseka kalula noma amagesi angenabuthi, ngaleyo ndlela kuncishiswe umthelela wawo emvelweni.Mayelana nokuphepha, izinto ezikhiqizwa noma ezisele ezinqubweni zepulasitiki ezibolayo azinabungozi emvelweni futhi akuthinti ukusinda kwabantu nezinye izinto eziphilayo.Isithiyo esikhulu sokushintsha amapulasitiki endabuko yiqiniso lokuthi ipulasitiki ebolayo ibiza kakhulu ukukhiqiza kunozakwabo abavamile noma abagaywe kabusha.Ngenxa yalokho, ipulasitiki ye-biodegradable inezinzuzo eziningi zokufaka esikhundleni sezinhlelo zokusebenza ezifana nokupakishwa, ifilimu yezolimo, njll., lapho isikhathi sokusebenzisa sifushane, ukubuyisela nokuhlukaniswa kunzima, izidingo zokusebenza aziphezulu, futhi izidingo zokuqukethwe kokungcola ziphezulu.
Izikhwama zokupakisha ezibolayo
Namuhla, ukukhiqizwa kwe-PLA ne-PBAT sekuvuthwe kakhulu, futhi umthamo wabo ophelele wokukhiqiza uphambili epulasitiki ebolayo, i-PLA inokusebenza okuhle kakhulu, futhi njengoba izindleko zehla, kulindeleke ukuthi zikhule zisuka emkhakheni wezokwelapha osezingeni eliphezulu ziye. imakethe enkulu efana nokupakishwa kanye nefilimu yezolimo esikhathini esizayo.Lawa mapulastiki e-Biodegradable angase abe enye indlela eyinhloko kumapulasitiki endabuko.
Izikhwama zepulasitiki okuthiwa ziyakwazi ukubola bezingakaguquki futhi zikwazi ukuthwala ukuthenga eminyakeni emithathu ngemuva kokuchayeka emvelweni, ucwaningo selutholile.
Ucwaningo lwahlola okokuqala izikhwama ezivundisiwe, izinhlobo ezimbili zezikhwama ezibolayo kanye nezikhwama ezijwayelekile zokuthwala ngemuva kokuchayeka isikhathi eside olwandle, emoyeni nasemhlabeni.Azikho izikhwama ezibole ngokuphelele kuzo zonke izindawo.
Isikhwama esivundisiwe sibonakala sihambe kangcono kunesikhwama esibizwa nge-biodegradable.Isampula lesikhwama esivundisiwe lanyamalala ngokuphelele ngemva kwezinyanga ezintathu endaweni yasolwandle kodwa abacwaningi bathi kudingeka umsebenzi owengeziwe ukuze kutholwe ukuthi iyini imikhiqizo ephukile futhi kubhekwe noma yimiphi imiphumela engase ibe khona kwezemvelo.
Ngokocwaningo, i-Asia ne-Oceania yenza amaphesenti angama-25 esidingo somhlaba wonke samapulasitiki abolayo, amathani angama-360,000 asetshenziswa emhlabeni jikelele.I-China yenza amaphesenti angu-12 esidingo somhlaba wonke samapulasitiki angaboli.Njengamanje, ukusetshenziswa kwamapulasitiki abolayo kuseyingcosana kakhulu, isabelo semakethe sisephansi kakhulu, ikakhulukazi amanani epulasitiki abolayo aphakeme, ngakho ukusebenza kwawo wonke akukuhle njengamapulasitiki ajwayelekile.Kodwa-ke, kuzothatha ingxenye enkulu emakethe njengoba abantu bekwazi ukubaluleka kokusebenzisa izikhwama ezibolayo ukuze kusindiswe umhlaba.Ngokuzayo, ngocwaningo olwengeziwe lobuchwepheshe bepulasitiki obubolayo, izindleko zizophinde zehliswe, futhi imakethe yezicelo zayo kulindeleke ukuthi iqhubeke nokukhula.
Ngakho-ke, izikhwama ze-biodegradable kancane kancane ziba yinketho yokuqala yamakhasimende.I-Top Pack igxile ekuthuthukiseni lolu hlobo lwezikhwama iminyaka eminingi futhi njalo ithola ukuphawula okuhle okuvela kuningi lamakhasimende.
