1. Amapulasitiki angaboli
Amapulasitiki e-biodegradable abhekisela kumapulasitiki anezinkomba zokusebenza ezihlukahlukene ezingahlangabezana nezidingo zokusebenza, izinkomba zokusebenza azishintshi phakathi nesikhathi seshelufu, futhi zingehliswa zibe izingxenye ezingangcolisi imvelo ngaphansi kwethonya lemvelo ngemva kokusetshenziswa.Ukuhlukaniswa kwamapulasitiki awonakalayo.Ngokwefomu lokuwohloka, amapulasitiki awonakaliswayo angahlukaniswa abe izigaba ezine: amapulasitiki angaboli, amapulasitiki angaboleka izithombe, amapulasitiki angaboli nezithombe, kanye namapulasitiki awonakaliswa ngamanzi.Ngokwezigaba zezinto zokusetshenziswa, amapulasitiki awonakaliswayo angahlukaniswa abe amapulasitiki abolayo kanye namapulasitiki awonakele asuselwa ku-petroleum.Izinzuzo zamapulasitiki awonakalayo.Amapulasitiki angaboli kahle anezinzuzo zawo ngokwezinkomba zokusebenza, ukusebenziseka, ukuwohloka, kanye nezindaba zokuphepha.Ngokwezinkomba zokusebenza, amapulasitiki awonakaliswayo angafinyelela noma adlule izinkomba zokusebenza zamapulasitiki endabuko kwezinye izici ezikhethekile;ngokwezinto eziwusizo, amapulasitiki awonakaliswayo anezinkomba ezifanayo zokusebenza kwesicelo kanye nokusebenza okuhlanzekile njengamapulasitiki endabuko ohlobo olufanayo;mayelana nokonakala Ngemva kokusetshenziswa, amapulasitiki awonakaliswayo angonakaliswa ngokushesha ngaphansi kwethonya lendawo yemvelo futhi aphenduke izingcezu noma amagesi angenabuthi asetshenziswa kalula imvelo yemvelo, ukunciphisa umthelela endaweni yemvelo;mayelana nezindaba zokuphepha, amapulasitiki awonakele Izingxenye noma izinsalela ezakhiwe ngesikhathi senqubo yokuwohloka ngeke zingcolise imvelo futhi ngeke kuthinte ukuphila kwabantu nezinye izinto eziphilayo.Isithiyo esiyinhloko sokushintsha amapulasitiki endabuko kulesi sigaba nakho kuwukungalungi kwamapulasitiki awonakele, okungukuthi izindleko zomkhiqizo wabo ziphakeme kunohlobo olufanayo lwamapulasitiki endabuko noma amapulasitiki agaywe kabusha.
2. Amapulasitiki agaywe kabusha
Amapulasitiki agaywe kabusha abhekisela ezintweni zokusetshenziswa zepulasitiki ezitholwe ngemva kokucubungula amapulasitiki okulahlwayo ngokusebenzisa izindlela ezingokwenyama noma zamakhemikhali ezifana nokwelashwa kusengaphambili, ukuncibilika kwembudumbudu, ukuguqulwa, njll. Inzuzo enkulu yamapulasitiki agaywe kabusha ukuthi intengo iphansi kunaleyo yezinto ezintsha namapulasitiki awonakele, futhi ingacubungula kuphela izici ezithile zezakhiwo zepulasitiki ngokwezidingo ezihlukene zenkomba yokusebenza, futhi ikhiqize imikhiqizo ehambisanayo.Uma nje imvamisa yokugaywa kabusha ingekho phezulu kakhulu, amapulasitiki agaywe kabusha angaqinisekisa izinkomba zokusebenza ezifanayo njengamapulasitiki omdabu, noma izinto ezigaywe kabusha zingaxutshwa nezinto ezintsha ukuze kugcinwe izinkomba zokusebenza ezizinzile.Kodwa-ke, ngemva kwemijikelezo eminingi, izinkomba zokusebenza zamapulasitiki agaywe kabusha ziyehla kakhulu noma zingasebenziseki.
3. Ipulasitiki ye-biodegradable pK eyenziwe kabusha
Ngokuqhathanisa, amapulasitiki awonakele anokusebenza okuzinzile kanye nezindleko eziphansi zokuphinda zisetshenziswe.Banenzuzo yokushintsha amaphakheji, amafilimu e-mulch yezolimo nezinye izinhlelo zokusebenza ezinezikhathi ezimfushane zokusebenzisa futhi ezingenakuhlukaniswa futhi ziphinde zisetshenziswe;kuyilapho amapulasitiki agaywe kabusha enawo Intengo ephansi nezindleko zokucubungula kunenzuzo kakhulu emikhakheni yokufaka isicelo njengezidingo zansuku zonke, izinto zokwakha, kanye nemishini kagesi enempilo ende yesevisi futhi kulula ukukuhlukanisa nokuphinda kusetshenziswe.Laba ababili bayaphelelisana.Ukungcola okumhlophe kuvela ikakhulukazi embonini yokupakisha, futhi amapulasitiki awonakele anendawo enkulu yokudlala.Ngokuthuthuka kwezinqubomgomo kanye nokwehliswa kwezindleko, imboni yepulasitiki eyonakalayo inamathemba abanzi esikhathini esizayo.Embonini yokupakisha, ukushintshwa kwamapulasitiki angaboli kahle sekusunguliwe.Amapulasitiki anezinhlobonhlobo zezicelo, futhi izimboni ezihlukene zinezindinganiso ezihlukene zamapulasitiki.Izidingo ezijwayelekile zamapulasitiki ezimbonini ezifana nezimoto nemishini yasendlini ukuthi ahlala isikhathi eside futhi kulula ukuwahlukanisa, futhi amapulasitiki angawodwa asetshenziswa ngobuningi, ngakho-ke isimo sepulasitiki yendabuko siqinile.Ezimbonini zokupakisha ezifana nezikhwama zepulasitiki zokufaka, amabhokisi okudla okusheshayo, amafilimu e-mulch yezolimo, kanye nokulethwa okucacile, ngoba ukusetshenziswa kwama-monomers epulasitiki kuphansi futhi kulula ukungcoliswa, awakwazi ukuhlukaniswa ngokuphumelelayo.Lokhu kwenza amapulasitiki awonakalayo abe maningi amathuba okuba athathelwe indawo yamapulasitiki endabuko kulezi zimboni.
Amapulasitiki abolayo ayikhambi elisebenza kahle kakhulu ekungcoleni okumhlophe kunokugaywa kabusha kwepulasitiki.U-59% wokunukubezeka okumhlophe uvela emikhiqizweni yepulasitiki yokupakishwa kanye ne-mulch yezolimo.Kodwa-ke, amapulasitiki alolu hlobo lokusetshenziswa ayalahlwa futhi kunzima ukuphinda asetshenziswe, okuwenza angafaneleki ukugaywa kabusha kwepulasitiki.Amapulasitiki awonakele kuphela angaxazulula inkinga yokungcola okumhlophe.Ngaphandle kwamapulasitiki anesitashi, isilinganiso senani lokuthengisa lamanye amapulasitiki awonakele liphindwe izikhathi ezingu-1.5 kuya kweziyi-4 kunezapulasitiki zendabuko.Lokhu kungenxa yokuthi inqubo yokukhiqiza amapulasitiki awonakele iyinkimbinkimbi futhi idinga ukusetshenziswa kwama-biomolecule emvelo abizayo ukuze kwenziwe i-polymerization, okwandisa ngokungabonakali izindleko zokukhiqiza.Ezimbonini ezizwelayo ezindleko nokusebenza, amapulasitiki endabuko asagcina izinzuzo zawo ngobukhulu, intengo nokusebenza okuphelele, futhi isikhundla sawo sihlala siqinile esikhathini esifushane.Amapulasitiki abolayo ngokuyinhloko athatha indawo yemboni yepulasitiki evamile eqhutshwa izinqubomgomo futhi ezwela amanani aphansi uma kuqhathaniswa.
