Yav dhau los, cov tshuaj perfluorinated PFAS coated rau sab hauv ntawm qee qhovntim khoom noj muaj qee yam carcinogenicity, yog li ntau tus neeg tsim khoom ntawm cov ntawv ntim khoom noj ceev ceev tig mus rau txheej txheej ntawm PE, PP, EVA, sarin thiab lwm yam yas yas zaj duab xis kom ua tiav lub hom phiaj ntawm cov dej tsis zoo thiab cov roj pov thawj, thiab kom tsis txhob kev puas tsuaj ntawm perfluorinated tshuaj rau tib neeg noj qab haus huv. Txawm li cas los xij, nyob rau hauv ib puag ncig ntuj, zoo li PFAS, cov qauv molecular ntawm cov yas zaj duab xis yog qhov ruaj khov thiab tsis tuaj yeem degraded, yog li ua rau cov yas dawb paug.
Yog li ntawd, qee lub tuam txhab tau tsim (anaerobic + marine) biodegradation thev naus laus zis rau cov khoom siv polymer (xws li yas, roj hmab, tshuaj fiber ntau), uas tuaj yeem ua tiav cov khoom pov tseg biodegradation, marine biodegradation, thiab compost degradation.
(Anaerobic + marine) biodegradation thev naus laus zis yog tus nqi qis tshaj, tus nqi ntxiv tsuas yog 1%, tus nqi tsuas yog nce los ntawm 20% -30%, thiab cov khoom siv qub, cov khoom siv ntau lawm, cov txheej txheem, thiab cov khoom ntawm cov khoom tsis muaj yuav tsum tau hloov. Nyob rau hauv sib piv, tus nqi ntawm tag nrho biodegradable technologies xws li PLA, PBAT, PBS, thiab PHA yuav nce los ntawm tsawg kawg yog 1-2 lub sij hawm, thiab tag nrho cov kev ua tau zoo ntawm cov khoom tiav tsis tuaj yeem ncav cuag qhov kev ua tau zoo ntawm cov yas yas. Hauv cov txheej txheem tsim khoom, cov khoom siv raw, cov khoom siv ntau lawm, cov txheej txheem tsim khoom, thiab lwm yam yuav tsum tau hloov kho thiab kho kom zoo.
Anaerobicbiodegradable masterbatch yog cov organic masterbatch uas tuaj yeem qhia cov yas rau hauv cov kab mob microbial degradation los ntawm kev ua haujlwm tshuaj lom neeg los ntawm cov kab mob (feem ntau yog cov kab mob anaerobic), tsuas yog cov pa roj carbon dioxide, methane thiab humus, cov methane yog siv los ua lub zog huv, humus tuaj yeem siv tau. chiv. Tom qab ntxiv anaerobic biodegradable masterbatch rau yas, nws tuaj yeem biodegraded hauv cov pov tseg los ntawm cov tshuaj tiv thaiv anaerobic, thiab tuaj yeem degraded hauv dej hiav txwv.
Anaerobic microbial degradation tshwm sim txhua lub sijhawm hauv qhov xwm txheej, thiab vim tias cov txheej txheem qeeb heev, nws tsis yooj yim los kuaj xyuas. Txawm li cas los xij, ntxiv anaerobic biodegradable masterbatch tuaj yeem ceev cov txheej txheem degradation ntawm cov khoom organic plastics. Anaerobic biodegradable masterbatch tso cai rau cov yas ua kom tiav plaub theem ntawm degradation ntawm tus nqi siab dua.
Nta thiab zoo heev ntawm (anaerobic + marine) biodegradation technology ntawmcoated ntawv:
1. huv thiab nyab xeeb. Cov cuab yeej siv no tuaj yeem siv los ua cov pa roj carbon monoxide rau cov kab mob anaerobic hauv ib puag ncig anaerobic, tom qab kev ua haujlwm enzymatic, kom txog rau thaum cov organic khoom carbon tau zom, nws ua tau raws li cov khoom siv ntsuab rau kev faib cov khib nyiab.
2. Tsis tas yuav hloov cov khoom siv ntau lawm, tsis tas yuav nqis peev hauv cov khoom siv tseem ceeb tshiab.
3. Nws tsis cuam tshuam rau kev ua haujlwm ntawm cov khoom qub thiab tsis ua rau tus nqi ntau dhau.
4. Nws tsis txwv los ntawm cov khoom txee lub neej thiab lub sijhawm cia.
5. Rov ua dua.
