Mabhegi epurasitiki atinoshandisa zuva rega rega akakonzera matambudziko makuru uye mitoro pane zvakatipoteredza.
Kana iwe uchida kutsiva mabhegi epurasitiki akajairwa nekusarudza mamwe "akaora" mabhegi epurasitiki, iwo anotevera pfungwa pamusoro peakaparara emabhegi epurasitiki achakubatsira iwe kuita sarudzo yakanaka yezvakatipoteredza!
Zvichida wakaona kuti pane "mabhegi epurasitiki anoparara" pamusika.Iwe unogona kufunga kuti mabhegi epurasitiki ane izwi rekuti "kuora" anofanirwa kuve akashata uye ane hushamwari.Zvisinei, izvi hazvisizvo.Chekutanga, chete kana mabhegi epurasitiki anogona kupedzisira aita zvinhu zvisingasvibise zvakaita semvura uye kabhoni dhaokisaidhi, anogona kunge ari mabhegi ane hushamwari zvechokwadi.Kune kunyanya akati wandei emabhegi epurasitiki "ane hushamwari kwezvakatipoteredza" pamusika: mabhegi epurasitiki anoparara, bhegi rinoodza, uye compostable bag.
Iyo polymer mubhegi repurasitiki yakakuvadzwa zvishoma kana zvachose nekuda kwemwaranzi yeultraviolet, oxidation corrosion, uye biological corrosion.Izvi zvinoreva shanduko yezvivakwa zvakaita sekupera, kutsemuka kwepamusoro, uye kutsemuka.Iyo biochemical process umo organic zvinhu mumabhegi epurasitiki inoshandurwa zvachose kana zvishoma kuita mvura, kabhoni dhaibhoni / methane, simba uye biomass nyowani pasi pekuita kwehutachiona (mabhakitiriya nefungi).Mabhegi epurasitiki anogona kuvandudzwa pasi pemamiriro akakosha uye chiyero chenguva yevhu-tembiricha, uye kazhinji zvinoda composting yemaindasitiri kuti iwane kuderedzwa kuri nani.
Kubva pamaonero matatu ari pamusoro, mabhegi anoodza kana kuti anosanganiswa ndiwo ari "kuchengetedzwa kwezvakatipoteredza" zvechokwadi!
Mhando yekutanga ye "yakaora" mabhegi epurasitiki anonyanya kusanganisira "photodegradation" kana "thermal oxygen degradation. Pakupedzisira, vanogona kungoshandura mabhegi epurasitiki kuita zvidimbu zvidiki zvepurasitiki, izvo zvisingakodzeri kudzokorodza uye kuchenesa mapurasitiki, asiwo kupatsanurwa. mapurasitiki.Kupinda kwezvakatipoteredza kuchakonzera mamwe matambudziko ekusvibiswa.Naizvozvo, iyi "inoora" bhegi repurasitiki harina hushamwari nemhoteredzo, uye rakakonzera kushorwa kwakanyanya muindasitiri.
Photodegradable mapurasitiki: mapurasitiki akasvibiswa nechiedza chechisikigo;mwenje ndewe ultraviolet mwaranzi, iyo inogona kungokonzeresa chikamu kana chakazara kukuvadza kune polymer.
Thermal oxidative degradation plastics: mapurasitiki akasvibiswa nekupisa uye / kana oxidation;thermal-oxidative degradation ndeye oxidative corrosion, iyo inogona kungokonzeresa chikamu kana kukuvara kwakazara kune polymer.Naizvozvo, dzidza kusiyanisa mabhegi epurasitiki akasiyana anoparara kana paine emergency!
Mabhegi epurasitiki akagadzirwa kare anofanirwa kucherechedzwa zvinoenderana nezviyero uye zvinhu zvinoshandiswa.Pakati pavo: chiratidzo chekudzokorora chinoratidza kuti bhegi repurasitiki rinogona kushandiswa zvakare uye kushandiswa zvakare;04 mucherechedzo wekudzokorodza chiratidzo chakakosha chedhijitari chitupa cheyakaderera-density polyethylene (LDPE);pasi pechiratidzo chekudzokorodza> PE-LD
Nokudaro, kana uchitenga bhegi rinogadziriswa kana kuti compostable, iwe unofanira kutanga watarisa kana pane logo yepurasitiki inodiwa nenyika pasi pehomwe.Wobva watonga zvinoenderana nemidziyo yekugadzira bhegi repurasitiki pasi pechinyorwa chekuchengetedza kwezvakatipoteredza.Iyo inowanzo shandiswa biodegradable kana compostable bag zvinhu ndeye PLA, PBAT, nezvimwe.
Shandisa bhegi repurasitiki rakashandiswa zvakanyanya sezvinobvira uye edza kuishandisa zvakanyanya sezvinobvira usati wairasa!
