Nrog txoj kev txhawb qib zuj zus ntawm cov "yas txwv", ntau thiab ntau tus neeg siv tau pib ua tib zoo mloog cov hnab yas degradable. Ntau tus neeg muas zaub yuav hloov mus rau cov hnab yas degradable, txawm li cas los ntau tus neeg muas zaub tsis paub qhov sib txawv, lub hnab yas zoo nkauj thiab cov hnab yas biodegradable. Cia kuv qhia koj rau koj.
Peb hom hnab yas hauv txhais, kom zoo dua thiab tsis zoo
Txhais:
● Cov hnab yas zoo tib yam yog lwm cov yas khoom xws li PE, thiab lub ntsiab tivthaiv yog cob. Looth hais txog cov polymer compound uas tsis tau sib xyaw nrog ntau yam ntxiv. Resin cov nyiaj tau rau txog 40 mus rau 100 feem pua ntawm tag nrho cov hnyav ntawm yas. Cov khoom tseem ceeb ntawm cov yas yog feem ntau txiav txim siab los ntawm qhov chaw cob, tab sis cov quav kuj tseem ua haujlwm tseem ceeb. Biodegradable Hnab yas muaj lub teb chaws ib puag ncig kev tiv thaiv tus qauv GB / T21661-2008, thaum lub hnab yas tsis tas yuav ua raws li cov qauv no. Cov hnab ntim khoom siv yas ua 200 xyoo lossis ntau dua los degree tom qab tau muab pov tseg. Ua rau "dawb paug" rau ib puag ncig.
● Degrigable Hnab yas yas: lub hnab yas uas txhais tau tias nws tuaj yeem muaj cov khoom xyaw yas thiab lwm yam cuam tshuam, tsis muaj qee qhov degraded, tsis yog ib nrab degraded, tsis yog ib nrab ntawm qhov tsis zoo. Nws yog yog ua los ntawm polyethylene yas, ntxiv nrog photOregrant thiab calcium carbonate thiab lwm cov mineral carbonate, tseem hu ua lub hnab ntim khoom yas. Hom hnab yas yas no yog decomposed hauv kev ua ntawm lub hnub ci. Txawm li cas los xij, tus polyethylene tom qab fen dilontamination tseem muaj nyob hauv ntuj ntuj ib puag ncig. Txawm hais tias lub hav zoov ntawm cov pa phem dawb tsis tuaj yeem pom hauv txoj kab pom, yog qhov muaj cov kab mob ib puag ncig hauv daim ntawv ntawm cov tsos mob me, uas tuaj yeem hais tau cov tsos mob me tab sis tsis yog lub hauv paus ua rau. Txhawm rau muab nws yooj yim, tom qab muab pov tseg lub hnab yas uas tsis taus, nws tseem yuav ua rau ib puag ncig rau ib qho, ib yam li lub hnab yas tsoos. Nws lub hom phiaj kawg yog qhov zoo ib yam li cov hnab yas tsoos. Tom qab tau muab pov tseg, lawv txhua tus nkag mus hauv av lossis yog incinerated, thiab tsis tuaj yeem ua rau muaj kev sib cav tshwj xeeb los ntawm kev muaj kev muaj kev lag luam tshwj xeeb. Yog li ntawd, "degradoable" tsuas yog "degradable", tsis sib npaug rau "tag nrho cov biodegradation". Hauv kev txiav txim zoo, lub hnab yas tsis muaj txiaj ntsig tsis yog kev daws teeb meem rau "dawb paug paug", tsis yog "panacea" los daws cov hnab yas yas. Hauv essence, nws tseem yuav tsim ntau cov khib nyiab, thiab lub hnab yas depadable lub hnab yas ua tsis yog degraded.
Biodegradable hnab yas biodegradable: cov khoom siv ntawm biodegradotable hnab yas yog tsim los ntawm PLA (polyacid) thiab pyadipic acid). Cov ntaub ntawv xws li no suav nrog Phas, PBA, PBS, thiab lwm yam, uas tau lees paub raws li cov ntaub ntawv phooj ywg ib puag ncig. Cov khoom lag luam ntsuab muaj teeb meem. Biodegradable Yas Hnab Khoom Siv Hnab, Kuj yog hais tias kev ua ntawm cov kab mob av uas muaj nyob hauv qab lossis cov huab cua kev daws teeb meem lossis cov kev cai daws teeb meem. Ua rau muaj kev cuam tshuam, thiab thaum kawg ua rau cov pa roj carbon dioxide (CO2), tshuaj mutters

Biodegradable Yas Hnab
Biodegradable Yas Hnabyog tag nrho biocompostable thiab cov neeg tu ncua lub hnab. Nyob rau hauv cov xwm txheej ntawm compost degradation, lawv tuaj yeem yog biodegraded kiag li tsis pub dhau 180 hnub. Cov khoom lag luam tsis zoo yog cov pa roj carbon dioxide thiab dej, uas ncaj qha nkag mus rau cov av thiab nqus tau los ntawm cov av, rov qab rau hauv av, lossis nkag mus rau qhov chaw dav dav. Nws tuaj yeem degraded yam tsis muaj kev ua qias tuaj rau ib puag ncig, yog li ntawd nws los ntawm xwm thiab belongs rau xwm.
