Mabhegi epurasitiki akakamurwa kuita mapoka maviri.Imwe ndeyekuora mabhegi ekutenga.Ibhegi rekutenga rakatipoteredza uye harikonzeri kusvibiswa nekukuvadza kune zvakatipoteredza.Shopping mabhegi.Nekuti mabhegi epurasitiki asingaparare achakonzera kukuvadza kwakawanda kune zvakatipoteredza, vanhu zvino vanosarudza kushandisa mabhegi ekutenga anoparara.Nekuwedzera kukosha kwekuchengetedzwa kwezvakatipoteredza, mabhegi epurasitiki anoshandiswa paanenge akonzera matambudziko akakomba uye mitoro pane zvakatipoteredza.Iko kudiwa kwekuderedzwa kwemabhegi epurasitiki mune ramangwana kucharamba kuchiwedzera.
Purasitiki yakasvibiswa, inozivikanwawo sepurasitiki yekushatisa kwezvakatipoteredza, inoreva mapurasitiki anowedzera imwe chiyero chekuwedzera mukugadzira nzira yekudzikisa kugadzikana kwayo, uye zviri nyore kushatisa munzvimbo yechisikigo.Nekuvandudzwa kwesainzi uye tekinoroji, mhando dzakasiyana dzemidziyo inogona kutsiva yechinyakare PE plastiki inooneka, inosanganisira PLA, PHAS, PBA, PBS uye zvimwe zvinhu zvepolymer.Ose ari maviri anogona kutsiva echinyakare PE epurasitiki mabhegi.Mabhegi epurasitiki anoshatisa ane hushamwari kwezvakatipoteredza ari kushandiswa zvakanyanya: nzvimbo huru dzekushandisa dzinosanganisira ivhu rekurima, mabhegi akasiyana epurasitiki ekurongedza, masaga emarara, mabhegi ezvitoro, uye midziyo yekudyira inoraswa.
Biodegradable plastiki inoreva mapurasitiki anokonzera kuparara nebasa rezvipembenene zvakaita sebhakitiriya, mold (fungi) uye algae iripo muzvisikwa.Iyo yakanakira biodegradable plastiki chikamu cheyakakwira mamorekuru zvinhu zvinogona kuodzwa zvachose nemasikirini ezvakatipoteredza mushure mekusiya, anogona kuodzwa zvachose nemasikirwo ezvakatipoteredza, uye pakupedzisira ave inorganic."Pepa" chinhu chakajairwa biodegradable zvinhu, uye "synthetic plastiki" ndeye yakajairika polymer zvinhu.Naizvozvo, biodegradable plastiki i polymer zvinhu zvine chimiro che "bepa" uye "synthetic plastiki".Biodegradable plastiki inogona kukamurwa kuita mhando mbiri: yakazara biodegradable plastiki uye inoparadza biodegradable plastiki
Inoparadza biodegradable purasitiki: Kuparadza biodegradable plastiki parizvino inonyanya kusanganisira starch shanduko (kana kuzadza) polyethylene PE, polypropylene PP, polyvinyl chloride PVC, polystyrene PS, nezvimwe.
Yakazara biodegradable plastiki: Yakazara biodegradable plastiki inogadzirwa zvakanyanya nemapolymer echisikigo (senge starch, cellulose, chitin) kana zvekurima uye zvepadivi zvigadzirwa.Polyester, polystrackic acid, starch / polyvinyl doro.
Kudzokororwa kwezvakagadzirwa zvemabhegi ekutenga
Iro bhegi repurasitiki rinoparara rinonzi zvakare mabhegi ekutenga anodedera.Inoshandisa chirimwa starch uye chibage hupfu, etc. Inogadzirwa nezvinhu zvakatorwa kubva mumiti.Izvi zvimisikidzwa hazvizokonzerese kukuvadza kumuviri wemunhu uye nharaunda.
Inogona kurapwa mumunda wevhu nemabhegi ekutenga anoparara.Zvinongotora nguva yakati kuti zvigadziriswe kuita biological particles zvobva zvatorwa nevhu.Iro bhegi repurasitiki rinoora haringove nemhedzisiro yezvakatipoteredza, asi rinogona kuvewo fetireza yezvirimwa nezvirimwa, zvichikurudzira kukura kwezvirimwa.
Nokudaro, kushandiswa kwezvikwama zvekutengesa zvakasvibiswa zvino zvave kufarirwa, uye kushandiswa kwezvikwama zvekutengesa zvisingabatsiri kunowedzerawo zvishoma nezvishoma.Hapana -kuora mabhegi ekutenga anokonzeresa kukuvadza kukuru kune hutano hwevanhu uye nharaunda.
Kukuvadza kwemasaga ekutenga asina kuparara
Zvinechekuita nemabhegi ekutenga anoshatisa haasi mabhegi ekutenga asina kuparara.Muchokwadi, mabhegi akajairwa ekutenga anogona zvakare kuderedzwa, asi akave akadzikiswa kwenguva yakareba kwemakore mazana maviri.Uyezve, kushandiswa kwemabhegi epurasitiki munharaunda yevanhu yakakura kwazvo.Kana ukashandisa mabhegi epurasitiki asingadzoreki, achaita kuti nharaunda yepasi iwedzere.
Vanhu havana nzira yakanaka yekudzokorodza marara emabhegi ezvitoro, kungave kupisa kana kurasira.Hapana mabhegi ekutenga anoshatisa achakanganisa nharaunda zvisinei nekuti ndeipi nzira.Semuenzaniso, kupisa kuchaburitsa kunhuhwirira kwakashata uye kuburitsa huwandu hukuru hwemadota madema;kana rikagadziriswa nemarara, pasi richatora mazana emakore kuti riore bhegi repurasitiki.
