1.Lub hnab Biodegradable yog dab tsi?
Biodegradable hnab kuj muaj npe hu ua compostable hnab, lub hnab tuaj yeem tawg hauv tej yam ntuj tso xws li av los yog xuab zeb, los yog nyob rau hauv tej yam kev mob xws li composting, anaerobic digestion, los yog nyob rau hauv dej. Cov txheej txheem no yog ua los ntawm cov kab mob uas muaj nyob hauv cov xwm txheej, thaum kawg tig cov yas rau hauv cov pa roj carbon dioxide (CO₂) lossis / thiab methane (CH₄), dej (H₂O), ntxhia ntsev ntawm cov khoom muaj nyob rau hauv cov yas, thiab cov biomass tshiab.
2.Lub hnab khib nyiab Biodegradable yog dab tsi?
Lub hnab ntim khoom biodegradable yog ua los ntawm cov khoom siv biodegradable. Cov ntaub ntawv biodegradable feem ntau yog muab los ntawm cov khoom siv txuas ntxiv dua tshiab xws li cov hmoov txhuv nplej siab. Lawv muaj peev xwm tsis tsuas decompose sai sai nyob rau hauv lub ntuj ib puag ncig tab sis kuj muab cov as-ham rau cov av thiab txhawb kev tsim ntawm ecological tshuav nyiaj li cas. Piv nrog rau cov hnab yas ib txwm siv, cov hnab ntim khoom siv no muaj cov pa roj carbon tsawg dua thiab cuam tshuam rau ib puag ncig.
Biodegradable hnab khib nyiab feem ntau yog tsim los ntawm kev sib xyaw ntawm cov ntaub ntawv hauv qab no:
2.1. PBAT (polybutylene adipate / terephthalate):
PBAT yog cov khoom sib xyaw ua ke ntawm biodegradable polyester thiab polypropylene glycol ester.
2.2. Pob kws
Cornstarch yog ib qho ntawm cov khoom siv tag nrho biodegradable khib nyiab hnab. Nws tuaj yeem muab rho tawm los ntawm ntau hom nroj tsuag xws li pob kws, qos yaj ywm, thiab lwm yam, thiab yog ib qho khoom siv txuas ntxiv. Cov ntaub ntawv pob kws tuaj yeem decompose sai sai nyob rau hauv ib puag ncig ntuj thiab yuav tsis ua phem rau cov av thiab dej.
2.3. Calcium Carbonate (CaCO3)
Lwm cov khoom siv hauv cov hnab khib nyiab biodegradable yog calcium carbonate (CaCO3). Cov tshuaj no feem ntau ntxiv rau cov hmoov txhuv nplej siab raws li cov yas los txhim kho lawv cov khoom thiab pab txhawb cov txheej txheem degradation.
2.4. PLA (polylactic acid)
PLA yog bioplastic tau los ntawm fermentation thiab purification ntawm cov nroj tsuag fibers los yog qab zib. Nws muaj cov yas zoo thiab tuaj yeem ua rau hauv lub hnab ntim khoom ntawm cov duab sib txawv thiab ntau thiab tsawg. PLA biodegradable hnab tuaj yeem degraded sai sai rau hauv cov pa roj carbon dioxide thiab dej raws li qhov tsim nyog.
Cov tuam txhab muaj zog yuav sib xyaw cov khoom siv raw li saum toj no rau hauv cov ntaub ntawv hloov pauv hauv qhov sib txawv, thiab tom qab ntawd tshuab zaj duab xis rau lub hnab ntim khoom los tsim cov khoom tiav. Cov hauv qab no yog ob peb yam khoom hloov kho:
Pawg 1: PBAT + Pob kws-raws li cov ntaub ntawv
Lub hnab khib nyiab biodegradable uas tsim los ntawm cov khoom siv hloov kho no yog qhov ntau tshaj plaws thiab tau txais los ntawm cov neeg siv khoom.
Qhov zoo ntawm cov khoom siv no lub hnab: zoo toughness, zoo tensile lub zog, thiab kev ua haujlwm siab.
Qhov tsis zoo: me ntsis ntawm cov hmoov txhuv nplej siab, qee cov neeg siv khoom tsis nyiam nws, thiab hom hnab no tsis haum rau qhov chaw kub.
Pawg 2:PBAT+ Caco3 --Cov ntaub ntawv raws li
Lub hnab khib nyiab biodegradable ua los ntawm cov khoom siv no muaj cov yam ntxwv ntawm kev ua haujlwm siab, zoo whiteness ntawm lub hnab ntuj, thiab kub-resistant.
Pab pawg 3: PBAT+ PLA --Raws li cov ntaub ntawv
Qhov kev sib xyaw ua ke no feem ntau yog siv rau hauv cov khoom ntim biodegradable uas yuav tsum tau muaj siab pob tshab, xws li biodegradable txiv hmab txiv ntoo thiab zaub hnab. Tus nqi ntawm cov khoom siv raw yog siab dua thawj ob cov ntaub ntawv hloov kho, thiab lub hnab ntim tau zoo dua nruj.
3. Yog tias koj tab tom nrhiav yuav cov hnab khib nyiab biodegradable, koj yuav xav paub txog cov lus nug hauv qab no:
3.1: Lub neej ntev npaum li cas ntawm Lub Hnab Biodegradable?
Lub txee lub neej ntawm cov hnab khib nyiab biodegradable no feem ntau yog ib xyoos, tab sis lub sijhawm caij nyoog kuj muaj feem xyuam nrog rau yam xws li qhov chaw cia khoom. Feem ntau nws yog 6 mus rau 9 lub hlis, thiab qee qhov tuaj yeem qeeb qeeb tom qab ib xyoos. Nws tsis pom zoo kom siv eco-phooj ywg hnab uas tau dhau los ntawm lawv lub txee lub neej, vim tias lub zog thiab tawv tawv ntawm lub hnab tau txo qis heev nyob rau lub sijhawm no, thiab lawv muaj feem cuam tshuam. Qhov no yog ib txwm degradation feature thiab ib tug degradation txheej txheem, tab sis nws yog ib tug zoo tshwm sim vim hais tias, tom qab degradation, nws yuav tsis ua paug rau ib puag ncig thiab xwm.
3.2: Thaum twg Biodegradable Bags pib degrade?
Biodegradable khib nyiab hnab muaj ntau lub sij hawm degradation vim muaj yam xws li cov khoom ib puag ncig thiab microbial hom. Nyob rau hauv ib puag ncig ntuj, lawv pib degrade tom qab 6 lub hlis, tab sis yuav tsis cuam tshuam cov khoom zoo thiab siv nyob rau hauv ib xyoos. Kev degradation yuav nrawm dua nyob rau hauv qhov kub thiab txias ib puag ncig. Nyob rau hauv qhov chaw sim ntawm lub tsev composting, lawv yuav degrade rau hauv dej thiab carbon dioxide nyob rau hauv 360 hnub, thiab nyob rau hauv industrial composting tej yam kev mob, lawv yuav degrade rau hauv dej thiab carbon dioxide nyob rau hauv 180 hnub.
3.3: Yuav khaws cov hnab Biodegradable li cas?
Yog tias khaws cia kaw, lub teeb-pov thawj, noo noo-pov thawj, thiab nyob rau hauv ib qho chaw txias, lub txee lub neej ntawm biodegradable hnab yog 10-12 hli.
4. Yuav ua li cas Biodegradable Hnab Degrade? Cov xwm txheej rau Degradation
Humidity:
Biodegradable hnab yas xav tau ib qho av noo kom degrade. Cov av noo tuaj yeem txhawb kev loj hlob thiab kev ua haujlwm ntawm cov kab mob microorganisms, yog li ua kom cov yas degradation sai.
Kub:
Kub kuj yog ib qho tseem ceeb ntawm kev degradation ntawm plastics. Kev kub siab dua tuaj yeem ua kom muaj kev ua haujlwm ntawm microbial metabolic, yog li ua kom tus nqi degradation. Feem ntau, qhov kub siab dua (30 degree txog 60 degree) yog qhov tsim nyog rau degradation.
Oxygen:
Oxygen tuaj yeem muab cov pa oxygen tsim nyog thiab kev siv lub zog rau cov kab mob kom ua rau cov txheej txheem degradation ua tau zoo. Txawm li cas los xij, tseem muaj cov ntaub ntawv yas uas tau hloov mus rau qhov degradation hauv cov xwm txheej tsis muaj oxygen, xws li cov chaw pov tseg.
Cov kab mob microorganisms:
Microorganisms yog tus yuam sij rau degradation. Lawv rhuav tshem cov yas molecules rau hauv cov khoom me me, thaum kawg txo cov yas rau nws cov khoom siv, xws li dej, carbon dioxide, thiab lwm yam khoom. Ntau hom kab mob muaj qhov sib txawv degradation zoo rau ntau hom yas.
Nws yuav tsum tau muab sau tseg tias biodegradable hnab khib nyiab degrade qeeb nyob rau hauv ib puag ncig tej yam kev mob, yog li yog hais tias lawv yuav degrade zoo, tej zaum lawv yuav tsum tau kho nyob rau hauv ntau haum tej yam kev mob, xws li nyob rau hauv ib tug mob siab rau industrial composting chaw.
5. Yuav Ua Li Cas Xaiv Cov Hnab Biodegradable tiag tiag
Authentic biodegradable hnab khib nyiab feem ntau muaj cov ntawv pov thawj los ntawm cov koom haum lees paub, xws li Biodegradable Products Institute (BPI, ABA, TUV, DIN) lossis European Standard EN 13432. Cov ntawv pov thawj no xyuas kom meej tias cov hnab ntim tau raws li cov txheej txheem tshwj xeeb rau biodegradability thiab compostability.
