Kodi thumba la biodegradable ndi chiyani

1.Biodegradation bag，Zikwama za biodegradation ndi matumba omwe amatha kuwola ndi mabakiteriya kapena zamoyo zina.Za 500 biliyoni mpaka 1 thililiyoni matumba apulasitiki amagwiritsidwa ntchito chaka chilichonse. Matumba a biodegradation ndi matumba omwe amatha kuwola ndi mabakiteriya kapena zamoyo zina. Pafupifupi 500 biliyoni mpaka 1 thililiyoni matumba apulasitiki amagwiritsidwa ntchito chaka chilichonse.
2.Kusiyanitsa pakati pa "biodegradable" ndi "compostable"
Mwachidule, mawu akuti biodegradable ali ndi tanthauzo losiyana ndi kompositi.Biodegradable amangotanthauza kuti zinthu zitha kuwola ndi mabakiteriya kapena zamoyo zina, ndipo "kompositi" mumakampani apulasitiki amatanthauzidwa ngati kuthekera kowola m'malo a aerobic omwe amasungidwa pazikhalidwe zinazake zowongolera komanso chinyezi.Compospost ndi kuthekera kwa biodecompose mumunda, kupanga zinthu zowola, zowoneka bwino komanso zowoneka bwino. madzi, mankhwala opangidwa ndi organic ndi biomass pamlingo wogwirizana ndi

Kuphatikizika kwa "zakuthupi" sikunaphatikizepo chinthu chomaliza kuti chisatengedwe ngati kompositi kapena humus, zomwe zimangokhala organic material.M'malo mwake, muyezo wa xxx wofunikira kuti pulasitiki imatchedwa kompositi pansi pa tanthauzo la ASTM ndikuti iyenera kutha pamlingo wofanana ndi chinthu china chomwe munthu amadziwa kale kuti kompositi pansi pa tanthauzo lachikhalidwe. Matumba apulasitiki amatha kupangidwa kuchokera ku polima wamba wa pulasitiki (mwachitsanzo, polyethylene) kapena polypropylene ndikusakaniza ndi chowonjezera chomwe chimayambitsa kuwonongeka kwa polima (polyethylene) kenako ndikuwonongeka chifukwa cha.
3.Zinthu za thumba biodegradable
zolimba monga zolimba komanso zodalirika monga matumba achikhalidwe (makamaka polyethylene). Matumba ambiri amapangidwanso ndi mapepala, zinthu zakuthupi, kapena polyhexanolactone. "Anthu amaona kuti biodegradable ndi chinthu chamatsenga," ngakhale kuti mawuwa amagwiritsidwa ntchito kwambiri, malinga ndi RamaniNarayan, katswiri wamankhwala ku East Lansing Michigan State University komanso mlangizi wa sayansi ku Institute for Biodegradable Plastics.
4.Kubwezeretsanso matumba a biodegradable.
Zinyalala za m'zomera zimatha kubwezeretsedwanso, koma zimakhala zovuta kuzisintha ndikuzibwezeretsanso pambuyo pa kudyedwa.Ma polima opangidwa ndi Bio-based amatha kuwononga kukonzanso kwa ma polima ena odziwika bwino.Ngakhale opanga mapulasitiki a aerobic biodegradable amati matumba awo amatha kubwezeretsedwanso, ambiri obwezeretsanso mafilimu apulasitiki sangawavomereze chifukwa palibe kafukufuku wanthawi yayitali pa kuthekera kwa zinthu zowonjezeredwa za Plastic Institute. (BPI) inanena kuti mapangidwe a zowonjezera mu mafilimu oxidized amasiyana mosiyanasiyana, zomwe zimabweretsa kusinthasintha kwakukulu pakubwezeretsanso.
