Cov hnab ntawv ntim tau muaj kev phom sij ntau dua li cov hnab yas, tab sis tsis muaj kev tsis muaj mob kiag li. Hauv qab no yog kev txheeb xyuas kev tiv thaiv ib puag ncig ib puag ncig, kev pheej hmoo noj qab haus huv, kev siv khoom noj, thiab lwm yam.
1.Txhua kev tiv thaiv kev tiv thaiv kev sib piv
tsis muaj txhij
Hnab yas:
Cov khoom siv raw tseem yog polyethylene (PE), polypropylene (PP), thiab lwm yam siv 20-1000 xyoo los rhuav tshem hauv ntuj ntuj.
Microplastics (cov yas hais tsawg dua li5mm hauv diam) daim ntawv thaum lub sij hawm decomposition, paug av thiab nkag rau hauv lub cev los ntawm cov khoom noj khoom noj.
Hnab Ntawv:
Ua los ntawm cov nroj tsuag ntuj cog fibers xws li ntoo, xyoob thiab straw, nws degrades nyob rau hauv ntuj rau rau lub hlis.
Kev ua rau hauv dej thiab cov pa roj carbon dioxide tsis ua rau ntev - xyoo ib puag ncig kev ua qias tuaj.
Ua Haujlwm Nqi
Hnab yas:
Tsawg dua 5 feem pua ​​ib xees yog tus nqi rov qab ua haujlwm thoob plaws ntiaj teb, nrog qhov sib npaug tseem ceeb yuav mus rau thaj chaw pov tseg lossis kev sib cais.
Incination ua lag luam Dioxins thiab lwm cov tshuaj lom neeg uas tsis huv thiab siv kev noj qab haus huv.
Hnab Ntawv:
Cov nqi ua haujlwm tau los ntawm 60 txog80 ib xees (tsim cov ntaub ntawv hauv lub tebchaws) thiab tuaj yeem rov ua dua tshiab rau hauv pulp, daim duab los yog ntim khoom.
Txawm hais tias tsis muaj kev rov ua dua tshiab, cov txheej txheem degradation yog ib puag ncig ntau ib puag ncig.
Ntau lawm epening
Hnab yas:
Cov khoom siv ntau lawm ntawm cov pob txha hauv cov roj av xws li roj av thiab emits kom muaj roj carbon dioxide loj thiab me me).
Ntxiv cov tshuab yas, cov stabilizers thiab lwm yam tshuaj tuaj yeem nrhiav rau hauv ib puag ncig thiab kev hem thawj npe.
Hnab Ntawv:
Kev tsim khoom yuav tsum tau nyob ruaj ruaj, tab sis qhov no tuaj yeem raug txo qis los ntawm kev siv cov ntawv sau ua dua tshiab lossis cov ntawv pov thawj FSC.
Cov txheej txheem papermakakaking ua kom cov chaw pov tseg thiab khib nyiab, tab sis cov thev naus laus zis tau zoo heev txo cov pa paug).
2. Kev sib piv ntawm kev pheej hmoo muaj kev noj qab haus huv
Kev phom sij ncaj qha
Hnab yas:
Cov khoom noj kub (xws li cov zaub mov kub) tuaj yeem tso cov tshuaj kub (xws li cov yas, bisphenol a) thiab cuam tshuam cov endocrine system.

Hnab Ntawv:
Khoom noj khoom haus -} daim ntawv qib me me, xws li daim ntawv greft thiab greasft ntawv, yog feem ntau} pub dawb thiab nyab xeeb.
Zam txhob siv cov ntawv sau ua lossis tsis muaj txiaj ntsig - Cov khoom zoo ntawv rau cov zaub mov roj los tiv thaiv kab mob los yog impurities los ntawm tsiv teb tsaws.
Kev mob siab tsis ncaj
Hnab yas:
Microuplastics ua kom muaj kuab lom dej thiab cov khoom noj khoom haus, muaj peev xwm ua kom muaj kev pheej hmoo mob cancer, kev ua me nyuam kab mob thiab ntau dua.
Dioxins los ntawm kev ua kom muaj zog yog cov carcinogenic thiab ntev - sij hawm} Lub sij hawm kis tau tuaj yeem tiv thaiv kab mob.
Hnab Ntawv:
Tsis muaj cov tshuaj lom tau tso cov txheej txheem tso tawm thiab tsis muaj kev hem thawj ncaj qha rau tib neeg kev noj qab haus huv.
Cov tshuaj tiv thaiv ntawm cov tshuaj ua kom siav, xws li cov tshuaj chlorine, yog kev txhawj xeeb, tab sis cov txheej txheem niaj hnub loj heev txo cov tshuaj dawb.
III. Kev sib piv cov khoom siv
Tau qhov twg los cov ntaub ntawv raw
Hnab yas:
Kev vam khom rau tsis - Cov peev txheej txuas ntxiv xws li cov roj tsis sib haum xeeb thiab cov kev tsis sib haum Geopolitical.
Hnab Ntawv:
Cia siab rau ntawm cov ntoo lossis cov ntawv rov ua dua tshiab, muaj kev ruaj ntseg hauv hav zoov ua kom muaj peev xwm ntxiv.
Kev siv ntawm cov tsis - wood raw khoom xws li quav nyab thiab xyoob muaj ntxiv txo cov kev siab ib puag ncig.
Kev Siv Zog
Hnab yas:
Kev siv hluav taws xob tsawg hauv kev tsim khoom (txog 2 g / hnab roj), tab sis nyuaj rau kev rov ua dua thiab siv hluav taws xob siab nyob rau hauv lub neej.
Hnab Ntawv:
Kev siv zog ntau 3 rau4 zaug ntau lub zog ua lub hnab yas (vim yog daim ntawv, kom qhuav thiab lwm yam khoom siv tsawg dua tsawg dua.
Cov hnab tuab, xws li hnab ntim khoom, xav tau ntau cov ntaub ntawv thiab yuav tsis tau ntsuas cov hnab yas uas lawv tau siv.
IV. Qhia Txog Cov Lus Qhia Txog Kev Siv Tau Ua Tau Zoo
Tus naj npawb ntawm cov sijhawm siv
Hnab yas:
Lub teeb yuag thiab ruaj khov thiab ruaj ruaj, nws tuaj yeem siv 3 rau lub sijhawm (xws li hauv lub hnab khib nyiab), tab sis yog qhov tseeb tau siv ib zaug.
Hnab Ntawv:
Load muaj peev xwm yog tsis muaj zog, nquag ua kom tawg thiab feem ntau yuav tsum tau siv dua (piv txwv li . 5-10 lub sij hawm) kom them cov nqi ib puag ncig.
Thickened tsim los yog cov khoom siv sib xyaw (xws li ntawv + txheej yas) tuaj yeem txhim kho durability tab sis tej zaum yuav txo qis kev cuam tshuam.
Cov xwm txheej kev yoog
Hnab yas:
Haum rau cov kua, cov khoom ntub lossis cov khoom uas xav tau ntev - sij hawm cia (xws li cov zaub mov khov).

V. Qhov Kawg thiab Kev Pom Zoo
Kev nce qib ib puag ncig: lub hnab ntim khoom> Hnab yas ruaj khov kho lub hnab yas> hnab yas tsoos.
Kev Noj Qab Haus Huv Kev Noj Qab Haus Huv: Ntawv Hnab (Cov Hnab Rau Khoom Noj) yog qis dua li cov hnab yas.
Qhov kev xaiv tau zoo:
Luv -}} siv siv: ua ntej ntawv ntim cov hnab thiab rov siv lawv ntau li ntau tau (piv txwv li cov hnab ntim).

Cov ntaub ntawv tshwj xeeb: Yog tias koj yuav tsum tau khaws cov kua lossis dej noo, koj tuaj yeem xaiv cov hnab yas depadable (xws li PLA cov ntaub ntawv).
Txoj cai tswjfwm thiab tus kheej:
Txhawb nqa "Kev Txiav Txim Txiav Me" thiab lub hnab ntim ntawv rov qab ua dua tshiab.
Txo ib qho -} siv ntim khoom thiab nqa koj lub hnab khw thiab dej.
