Polylactic acid (PLA) yog ib qho tshiab biodegradable hnab yas khoom ua los ntawm cov hmoov txhuv nplej siab muab rho tawm los ntawm cov nroj tsuag txuas ntxiv xws li pob kws.Nws muaj biodegradability zoo thiab tuaj yeem degraded tag nrho los ntawm cov kab mob hauv cov xwm txheej tom qab siv, nws thiaj li tsim cov pa roj carbon dioxide thiab dej.Nws tsis ua phem rau ib puag ncig, muaj txiaj ntsig zoo rau kev tiv thaiv ib puag ncig, raug lees paub tias yog ib puag ncig tiv thaiv cov khoom siv.
Nyob rau hauv biodegradable hnab yas raw cov ntaub ntawv, polylactic acid (PLA) yog lub npe hu ua ib tug ntawm cov ntau yam nrog rau feem ntau txoj kev loj hlob muaj peev xwm, nrog rau biocompatibility, biodegradability thiab resource regeneration muaj peev xwm.Nyob rau hauv ib puag ncig ntuj, PLA pov tseg tuaj yeem degraded rau hauv CO2 thiab H2O los ntawm cov txheej txheem lom neeg lom neeg xws li hydrolysis (6-12 lub hlis).Cov CO2 thiab H2O no tuaj yeem siv los ntawm cov nroj tsuag los tsim cov hmoov txhuv nplej siab thaum lub sij hawm photosynthesis, uas tuaj yeem siv los tsim polylactic acid dua.Yog li ntawd, POlylactic acid tsis yog tsuas yog ib qho khoom siv tsis tau xwb, tab sis kuj tuaj yeem txo cov pa phem dawb, txuag cov peev txheej roj, thiab yog cov khoom siv uas tuaj yeem tswj tau "carbon voj voog sib npaug" hauv qhov xwm txheej.
Lub sijhawm tiag tiag nws yuav siv rau lub hnab ntim khoom siv biodegradable kom decompose nyob ntawm ntau yam, xws li qhov kub thiab txias.Compostable hnab tuaj yeem biodegrade hauv 30 hnub hauv kev lag luam composting thiab hauv 90 hnub hauv tsev composting systems.
Tam sim no peb tsim: biodegradable kas fes hnab, biodegradable tshuaj yej hnab.Biodegradable hnab nrog lub tiaj, biodegradable sab foob hnab, biodegradable zaub mov ntim hnab, biodegradable sawv ntsug zipper hnab, biodegradable 3-sab thiab lwm yam, peb cov khoom muag muag ntau tshaj 20 lub teb chaws thoob ntiaj teb, muaj ntau ntau thiab cov qauv, yog tias koj muaj. qhov kev thov ntawm lub hnab biodegradable, thov hu rau peb, peb yuav muab cov kev daws teeb meem zoo tshaj plaws rau koj, Cia koj cov khoom muag zoo dua.Thiab ua hauj lwm nrog peb los tiv thaiv lub ntiaj teb.
