Dab tsi yog ntsuab ib puag ncig tiv thaiv khoom?
Cov ntaub ntawv ntsuab thiab ib puag ncig tus phooj ywg xa mus rau cov ntaub ntawv uas ua tau raws li Kev Ntsuas Lub Neej Kev Ntsuas hauv cov txheej txheem ntawm kev tsim, siv, thiab rov ua dua tshiab, yooj yim rau tib neeg siv thiab tsis ua rau muaj kev puas tsuaj rau ib puag ncig, thiab tuaj yeem degraded los yog rov ua dua tom qab siv.
Tam sim no, cov khoom ntim khoom siv ntsuab thiab cov phooj ywg zoo ib puag ncig feem ntau suav nrog: cov khoom siv ntawv, cov khoom siv roj ntsha, cov ntaub ntawv degradable, thiab cov khoom siv tau.
1. Cov ntaub ntawv ntawv
Cov ntaub ntawv ntawv yog los ntawm cov khoom siv ntoo thiab muaj qhov zoo ntawm kev degradation sai thiab yooj yim rov ua dua.Nws yog cov khoom ntim ntsuab uas muaj ntau tshaj plaws nrog cov ntawv thov dav tshaj plaws thiab lub sijhawm siv ntxov tshaj plaws hauv Suav teb.Nws cov neeg sawv cev feem ntau suav nrog honeycomb paperboard, pulp molding thiab lwm yam.
Tom qab siv cov ntawv ntim, tsis tsuas yog nws yuav tsis ua kom muaj kuab paug thiab kev puas tsuaj rau ecology, tab sis nws tuaj yeem degraded rau hauv cov as-ham.Yog li ntawd, niaj hnub no kev sib tw hnyav rau cov ntaub ntawv ntim khoom, cov ntawv ntim ntawv tseem muaj qhov chaw hauv kev ua lag luam, txawm hais tias nws cuam tshuam los ntawm cov khoom siv yas thiab cov khoom ua npuas ncauj.

2. Cov khoom ntim khoom siv roj ntsha
Cov khoom ntim khoom siv roj ntsha feem ntau suav nrog cov khoom siv fiber ntau thiab cov khoom siv hmoov txhuv nplej siab, ntawm cov nroj tsuag ntuj fibers suav nrog ntau dua 80%, uas muaj qhov zoo ntawm qhov tsis muaj kuab paug thiab rov ua dua tshiab.Tom qab siv, nws tuaj yeem hloov mus rau hauv cov khoom noj khoom haus zoo, ua kom muaj txiaj ntsig zoo ntawm lub voj voog ntawm ntuj mus rau qhov xwm txheej.
Qee cov nroj tsuag yog cov khoom ntim ntuj, uas tuaj yeem ua ntsuab thiab tshiab ntim nrog me ntsis ua, xws li nplooj, reeds, gourds, xyoob raj, thiab lwm yam. Cov tsos zoo nkauj tsuas yog ib qho txiaj ntsig me me ntawm hom ntim no uas tsis tsim nyog hais.Qhov tseem ceeb tshaj, nws tseem tuaj yeem tso cai rau tib neeg kom muaj kev paub dhau los ntawm qhov qub ecology ntawm xwm!

3. Cov khoom siv degradable
Cov ntaub ntawv degradable feem ntau yog los ntawm cov yas, ntxiv cov photosensitizer, hloov cov hmoov txhuv nplej siab, biodegradant thiab lwm yam ntaub ntawv raw.Thiab los ntawm cov ntaub ntawv raw los txo cov kev ruaj ntseg ntawm cov yas ib txwm, ua kom lawv cov degradation nyob rau hauv ib puag ncig ntuj, thiaj li yuav txo tau cov pa phem rau lub ntuj.
Tam sim no, cov neeg laus dua yog cov khoom siv degradable, xws li cov hmoov txhuv nplej siab, polylactic acid, PVA zaj duab xis, thiab lwm yam. Lwm cov ntaub ntawv tshiab degradable, xws li cellulose, chitosan, protein, thiab lwm yam kuj muaj peev xwm loj hlob.

4. Cov khoom noj khoom haus
Cov khoom noj khoom haus yog tsim los ntawm cov ntaub ntawv uas tuaj yeem noj ncaj qha lossis noj los ntawm tib neeg lub cev, xws li lipids, fibers, starch, proteins, thiab lwm yam. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, cov ntaub ntawv no tau maj mam tshwm sim thiab loj hlob nyob rau xyoo tas los no. .Txawm li cas los xij, vim tias nws yog cov khoom noj khoom haus-qib raw khoom thiab yuav tsum muaj kev tu cev nruj thaum lub sijhawm tsim khoom, nws cov nqi tsim khoom kuj yog siab heev thiab nws tsis yooj yim rau kev lag luam siv.
Los ntawm qhov kev xav ntawm cov ntim ntsuab, qhov kev xaiv zoo tshaj plaws yog tsis ntim lossis ntim tsawg kawg nkaus, uas yog tsim los tshem tawm cov kev cuam tshuam ntawm ntim rau ib puag ncig;Qhov thib ob yog rov qab tau, rov qab siv tau lossis ntim rov ua dua tshiab, nws cov khoom siv rov ua dua tshiab thiab cov txiaj ntsig yog nyob ntawm cov txheej txheem rov ua dua tshiab thiab cov neeg siv khoom lub tswv yim.
Ntawm cov khoom ntim ntsuab, "degradable ntim" yog dhau los ua tus qauv yav tom ntej.Nrog rau qhov "txheej txheem yas" nyob rau hauv tag nrho viav vias, cov hnab yas tsis-degradable khw muag khoom raug txwv, degradable yas thiab ntawv ntim khoom lag luam tau nkag mus rau lub sijhawm tawg.
Yog li ntawd, tsuas yog thaum cov tib neeg thiab cov lag luam koom nrog kev hloov kho ntsuab ntawm kev txo cov yas thiab cov pa roj carbon monoxide tuaj yeem ua rau peb lub hnub qub xiav zoo dua thiab zoo dua.
5. Kraft ntim
Kraft daim ntawv hnab yog non-toxic, tasteless, thiab tsis muaj kuab paug.Lawv ua tau raws li cov qauv kev tiv thaiv ib puag ncig hauv tebchaws.Lawv yog cov muaj zog thiab ib puag ncig zoo.Tam sim no lawv yog ib qho ntawm cov khoom siv ntim khoom zoo tshaj plaws hauv ntiaj teb.
Kraft daim ntawv yog raws li tag nrho cov ntoo pulp ntawv.Cov xim yog muab faib ua dawb kraft ntawv thiab daj kraft ntawv.Ib txheej ntawm zaj duab xis tuaj yeem coated nrog PP khoom ntawm daim ntawv los ua lub luag haujlwm tsis muaj dej.Lub zog ntawm lub hnab tuaj yeem ua rau ib mus rau rau txheej raws li cov neeg siv khoom xav tau.Kev koom ua ke ntawm kev luam ntawv thiab lub hnab ua.Txoj kev qhib thiab rov qab sealing yog muab faib ua cua sov sealing, ntawv sealing thiab pas dej hauv qab.
Raws li peb txhua tus paub, kraft ntawv yog cov khoom siv rov ua dua tshiab.Cov ntaub ntawv raw rau papermaking yog cov nroj tsuag fibers.Ntxiv nrog rau peb lub ntsiab lus tseem ceeb ntawm cellulose, hemicellulose, thiab lignin, cov khoom siv raw kuj tseem muaj lwm cov khoom uas muaj cov ntsiab lus tsawg, xws li resin thiab tshauv.Tsis tas li ntawd, muaj cov khoom xyaw xws li sodium sulfate.Ntxiv rau cov nroj tsuag fibers hauv daim ntawv, cov khoom sib txawv yuav tsum tau ntxiv raws li cov ntaub ntawv sib txawv.
Tam sim no, cov khoom siv raw rau kev tsim cov ntawv kraft feem ntau yog cov ntoo thiab cov ntawv pov tseg rov ua dua tshiab, uas yog tag nrho cov peev txheej txuas ntxiv.Cov yam ntxwv ntawm degradable thiab recyclable yog ib txwm sau nrog cov ntawv ntsuab.
