Lub thawv noj su qis dua yog hais txog lub thawv noj su uas tuaj yeem muaj cov tshuaj lom biochemical raws li kev ua ntawm cov kab mob me me ib puag ncig (kab mob, pwm, algae) enzymes, ua rau pom qhov tsis zoo ntawm sab hauv kom hloov sab hauv, thiab thaum kawg tsim cov pa roj carbon dioxide thiab dej Cov. Tag nrho cov txheej txheem ua rau ploj mus ua rau cov khoom tsis muaj mob uas tsis muaj tib neeg koom nrog, uas yog cov txheej txheem ntev heev. Ntxiv rau qhov kev puas tsuaj ntawm qhov kev noj zaub mov ntim cov zaub mov pov tseg cov khoom pov tseg raws li GB18006.3-2020" General Technical xav tau rau Kev Siv Cov Khoom Siv Txiav Txim Siab Txiav Txim Siab" tu cov av huv thiab qhov ntom av-kom sov siab. Cov.
Biodegradable su thawv siv ob yam khoom siv: ib qho yog tsim los ntawm cov khoom siv ntuj tsim, xws li cov khoom lag luam ntawv, straw, hmoov txhuv nplej siab, thiab lwm yam, uas yog biodegradable thiab kuj hu ua cov khoom lag luam ib puag ncig; lwm qhov yog ua los ntawm cov yas yog cov khoom tseem ceeb thiab ntxiv cov hmoov txhuv nplej siab, Photosensitizer thiab lwm yam tshuaj.
1. Degradable ntuj cov khoom noj thawv
Cov zaub mov pov tseg tsis zoo uas tsim los ntawm cov khoom siv ntuj tsim kuj tseem hu ua lub thawv ntim khoom noj khoom haus biodegradable. Lub thawv ntim su biodegradable yog qhov khoom ua tau nce siab zoo rau ib puag ncig. Nws siv cov hmoov txhuv nplej siab los ua cov khoom siv tseem ceeb, ntxiv txhua xyoo cov nroj tsuag tshuaj fiber ntau thiab cov khoom siv tshwj xeeb, thiab ua tiav los ntawm cov tshuaj lom neeg thiab lub cev txoj kev los ua biodegradable vas nthiv zaub mov thawv. Vim tias cov hmoov txhuv nplej siab yog biodegradable natural polymer, nws yog decomposed rau hauv qabzib hauv qab qhov kev ua ntawm cov kab mob me me, thiab thaum kawg decomposed rau hauv dej thiab carbon dioxide. Tsis tas li ntawd, cov khoom siv sib xyaw nrog nws kuj yog cov khoom siv uas muaj qhov tsis zoo, yog li nws tuaj yeem hais tau tias nws tsis muaj kev cuam tshuam ib puag ncig. Lub hauv paus tseem ceeb ntawm cov khoom siv cov hmoov txhuv nplej siab tuaj yeem yog pob kws, qos yaj ywm, qos qos, qos ntoo thiab lwm yam nroj tsuag txhua xyoo-cog. Lub thawv noj su biodegradable zoo nkauj tsis zoo tag nrho. Piv txwv li, feem ntau ntawm cov ntaub ntawv tsim tawm yog cov khoom noj qoob loo, thiab cov teeb meem ntawm anti-mildew tseem tsis tau daws.
2. Lub thawv ntim khoom noj khoom haus hnab yas biodegradable
Cov ntaub ntawv raw rau lub hnab ntim khoom noj uas siv pov tseg no yog cov yas uas tsis zoo. Lub npe hu ua degradable plastics yog qhov sib ntxiv ntawm qee qhov ntxiv ntawm cov khoom ntxiv, xws li photosensitizers, hmoov txhuv nplej siab thiab lwm yam ntaub ntawv nyoos thaum lub sijhawm txheej txheem yas tsim. Nyob rau hauv txoj kev no, cov khoom siv degradable yas tuaj yeem tawg ua tej tawg ntaws los ntawm cov duab ua tiav tom qab siv thiab 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 qhov thev naus laus zis yog tias cov tawg tsam no tsis tuaj yeem txuas ntxiv mus ua degraded. Lawv tsuas yog tig los ntawm cov ntawv loj ua cov ntawv me me, thiab tsis muaj peev xwm ua lub luag haujlwm ntawm kev tshem tawm cov pa phem dawb.
