Lub teb chaws tam sim no tau tawm tswv yim tiv thaiv ib puag ncig, thiab kev lag luam nqa tawm tau maj mam hloov cov thawv noj su uas siv tau yooj yim nrog biodegradable tableware kom txo tau cov pa phem tawm. Yog li dab tsi yog biodegradable noj su box? Dab tsi yog cov khoom xyaw tseem ceeb ntawm biodegradable pov tseg noj su lub thawv? Lub thawv ntim khoom noj uas tsis muaj pov tseg yog hais txog cov tais diav uas thaum kawg tuaj yeem degrade rau hauv carbon dioxide thiab dej. Ib qho ntawm cov ntaub ntawv ntawm lub thawv noj su uas degradable yog ua los ntawm cov ntaub ntawv ntuj; lwm yam yog ua los ntawm yas ua lub ntsiab tivthaiv, ntxiv starch, photosensitizer thiab lwm yam khoom. ua.
1. Lub thawv noj su uas degradable yog dab tsi?
Lub thawv noj su uas degradable yog hais txog lub thawv noj su uas tuaj yeem ua rau cov tshuaj tiv thaiv biochemical nyob rau hauv qhov kev txiav txim ntawm ib puag ncig cov kab mob (cov kab mob, pwm, algae) enzymes, ua rau cov tsos ntawm mildew mus rau hauv kev hloov zoo, thiab thaum kawg tsim carbon dioxide thiab dej. Tag nrho cov txheej txheem degradation tuaj yeem decomposed rau hauv cov khoom tsis zoo yam tsis muaj tib neeg kev koom tes, uas yog txheej txheem ntev heev. Ntxiv rau qhov kev ua tau zoo ntawm cov khoom siv degradable lub thawv ntim khoom pov tseg yuav tsum ua kom tau raws li qhov kev ua haujlwm degradation ntawm GB18006.3-2020" General Technical Requirements for Disposable Degradable Tableware", nws yuav tsum muaj cov nqi rov ua dua, yog yooj yim rau kev rov ua dua tshiab, los yog yooj yim rau kev huv huv pov tseg thiab kub-kub composting.
2. Dab tsi yog cov khoom tseem ceeb ntawm cov khoom noj khoom haus biodegradable pov tseg?
Biodegradable noj su lub thawv siv ob hom khoom: ib qho yog ua los ntawm cov khoom siv ntuj tsim, xws li cov khoom siv ntawv, straw, starch, thiab lwm yam., uas yog biodegradable thiab tseem hu ua cov khoom zoo ib puag ncig; lwm yam yog ua los ntawm yas ua lub ntsiab tivthaiv thiab ntxiv nrog starch, Photosensitizer thiab lwm yam khoom.
1. Degradable tej yam ntuj tso khoom noj su box
Cov thawv ntim khoom noj uas tau muab pov tseg ua los ntawm cov khoom siv ntuj tsim los kuj hu ua biodegradable noj su thawv. Lub thawv noj su biodegradable yog cov khoom lag luam zoo ib puag ncig. Nws siv cov hmoov txhuv nplej siab ua cov khoom siv tseem ceeb, ntxiv cov nroj tsuag fiber ntau txhua xyoo thiab cov khoom siv tshwj xeeb, thiab ua tiav los ntawm cov txheej txheem tshuaj thiab lub cev los ua lub thawv khoom noj ceev biodegradable. Vim cov hmoov txhuv nplej siab yog biodegradable ntuj polymer, nws decomposed rau hauv qabzib nyob rau hauv kev ua ntawm cov kab mob, thiab thaum kawg decomposed rau hauv dej thiab carbon dioxide. Tsis tas li ntawd, cov khoom sib xyaw nrog nws kuj yog cov khoom siv degradable tag nrho, yog li nws tuaj yeem hais tias nws tsis muaj kev cuam tshuam rau ib puag ncig. Lub hauv paus tseem ceeb ntawm cov hmoov txhuv nplej siab tuaj yeem yog pob kws, qos yaj ywm, qos yaj ywm qab zib, cassava thiab lwm yam nroj tsuag loj hlob txhua xyoo. Lawm, biodegradable noj su thawv tsis zoo tag nrho. Piv txwv li, feem ntau ntawm cov ntaub ntawv tsim khoom yog cov qoob loo zaub mov, thiab cov teeb meem ntawm kev tiv thaiv mildew tseem tsis tau daws.
2. Biodegradable yas noj su lub thawv
Cov ntaub ntawv raw rau hom khoom noj su uas siv tau pov tseg yog cov yas degradable. Lub npe hu ua degradable plastics yog qhov sib ntxiv ntawm qee yam ntawm cov khoom siv ntxiv, xws li photosensitizers, hmoov txhuv nplej siab thiab lwm yam khoom siv raw thaum lub sijhawm tsim cov yas. Nyob rau hauv txoj kev no, cov khoom siv yas degradable tuaj yeem tawg mus rau hauv cov khoom tawg los ntawm cov duab tiav tom qab siv thiab muab pov tseg thiab raug rau xwm rau peb lub hlis, yog li tsawg kawg pom kev txhim kho ib puag ncig. Tab sis qhov teeb meem loj tshaj plaws ntawm cov thev naus laus zis no yog tias cov khoom tawg no tsis tuaj yeem txuas ntxiv mus rau degraded. Lawv tsuas yog tig los ntawm cov khoom loj rau hauv cov khoom me me ntawm cov yas thiab tsis muaj peev xwm ua haujlwm hauv kev tshem tawm cov pa phem dawb.
