Cov hnab yas tau raug tsim tawm ntawm kev nce mus txog ib trillion hnab txhua xyoo. Ntau txhiab lub tuam txhab yas thoob ntiaj teb ua ntau lub hnab yas siv rau kev yuav khoom vim lawv qhov yooj yim, tus nqi qis, thiab yooj yim.
Cov hnab yas khib nyiab tsim muaj kuab paug rau ntau txoj hauv kev. Ntau cov ntaub ntawv sib txawv qhia tau tias cov hnab yas ua paug rau ib puag ncig thiab ua rau tib neeg thiab tsiaj noj qab haus huv hauv nroog thiab nyob deb nroog. Ib qho teeb meem yog qhov poob ntawm kev zoo nkauj ntuj thiab cuam tshuam nrog cov khib nyiab yas yog kev tuag ntawm cov tsiaj nyeg thiab tsiaj qus. Qhov no tej zaum yuav yog vim tsis muaj kev tswj xyuas pov tseg thiab/lossis kev nkag siab yuam kev txog kev puas tsuaj ntawm cov hnab yas.
Kev txhawj xeeb loj hlob txog qhov cuam tshuam ntawm cov hnab yas rau ib puag ncig thiab kev ua liaj ua teb tau ua rau ntau lub tseem fwv txwv tsis pub lawv. Nws yog ib qho tseem ceeb los daws cov teeb meem ntawm cov hnab yas pov tseg vim tias cov khoom lag luam ua ntej tau nqa hauv ntawv, paj rwb, thiab pob tawb hauv paus txawm. Cov kua dej tau muab khaws cia rau hauv ceramic thiab iav ntim. Tib neeg yuav tsum raug cob qhia kom tsis txhob siv cov hnab yas es tsis txhob siv cov ntaub, ntuj fibers, thiab hnab cellophane.
Tam sim no peb siv cellophane hauv ntau txoj hauv kev - khaws zaub mov, khaws cia, nthuav qhia khoom plig, thiab kev thauj khoom. Nws yog qhov zoo nkauj tiv taus cov kab mob lossis microbes feem ntau, huab cua, noo noo, thiab txawm tias cua sov. Qhov no ua rau nws mus-rau kev xaiv rau ntim.
Cellophane yog nyias, pob tshab thiab glossy zaj duab xis ua los ntawm regenerated cellulose. Nws yog tsim los ntawm shredded ntoo pulp, uas yog kho nrog caustic soda. Lub thiaj li hu ua viscose yog tom qab extruded rau hauv ib da dej ntawm dilute sulfuric acid thiab sodium sulfate los tsim cov cellulose. Tom qab ntawd nws yog ntxuav, purified, bleached thiab plasticized nrog glycerin los tiv thaiv zaj duab xis los ntawm nkig. Feem ntau cov txheej xws li PVDC yog siv rau ntawm ob sab ntawm zaj duab xis los muab cov dej noo zoo dua thiab cov khoom thaiv roj thiab ua kom cov yeeb yaj kiab kub sealable.
Coated cellophane muaj tsawg permeability rau gasses, zoo tiv taus roj, roj, thiab dej, uas ua rau nws haum rau ntim khoom noj. Nws kuj tseem muaj qhov cuam tshuam me me ntawm cov dej noo thiab yog luam tawm nrog cov pa tshuaj ntsuam thiab offset luam ntawv txoj kev.
Cellophane yog tag nrho recyclable thiab biodegradable nyob rau hauv tsev composting ib puag ncig, thiab feem ntau yuav tawg nyob rau hauv ob peb lub lis piam.
Dab tsi yog cov txiaj ntsig ntawm cellophane?
1.Kev noj qab haus huv ntim rau cov khoom noj khoom haus yog ib qho ntawm cov khoom siv cellophane sab saum toj. Raws li lawv tau pom zoo los ntawm FDA, koj tuaj yeem khaws cov khoom noj tau zoo hauv lawv.
Lawv khaws cov khoom noj tshiab kom ntev ntev tom qab ua kom sov. Qhov no suav nrog cov txiaj ntsig ntawm cov hnab cellophane vim tias lawv ua rau lub neej txee ntawm cov khoom los ntawm kev tiv thaiv lawv ntawm dej, av, thiab plua plav.
2.Yog tias koj muaj lub khw muag khoom kim heev, koj yuav tsum tau xaj cov hnab cellophane hauv ntau vim lawv yuav siv tau rau koj!Cov hnab ntshiab no zoo meej rau khaws cov khoom me me hauv koj lub khw.

Qhov tsis zoo ntawm cov hnab yas
Cov hnab yas pov tseg ua rau muaj kev phom sij rau tib neeg thiab tsiaj txhu noj qab haus huv vim tias lawv raug pov rau hauv qhov chaw pov tseg thoob ntiaj teb, siv ntau qhov chaw thiab tawm cov pa phem methane thiab carbon dioxide emissions, nrog rau cov pa phem heev.
Vim tias cov hnab yas siv sijhawm ntev los ua kom tawg, lawv ua rau ib puag ncig puas. Sun-dried hnab yas tsim teeb meem molecules, thiab hlawv lawv tso cov tshuaj lom rau hauv huab cua, ua rau muaj kuab paug.
Tsiaj txhu feem ntau yuam kev lub hnab rau zaub mov thiab noj lawv thiab tej zaum yuav nkag mus rau hauv hnab yas thiab poob dej. Cov yas
muaj ntau zuj zus nyob rau hauv lub marine ecosystem, yuav tsum tau tam sim ntawd ua paug nyob rau hauv marine thiab dej tshiab tej chaw tsuas yog tsis ntev los no tau hais tias yog ib qho kev txhawj xeeb thoob ntiaj teb.
Trapped shoreline yas tsim kev puas tsuaj rau shipping, zog, nuv ntses, thiab aquaculture. Cov hnab yas hauv dej hiav txwv yog qhov teeb meem loj thoob ntiaj teb. Ua kom muaj kab mob ntau ntxiv los ntawm kev ua haujlwm lossis cov pa phem hauv huab cua. Cov tshuaj xau los ntawm cov hnab yas tau txuas mus rau qib toxicity ntau ntxiv.
Cov hnab yas hem ob qho tib si marine thiab ua liaj ua teb lub neej. Yog li ntawd, cov hnab yas tau unwittingly depleted tsim nyog lub ntiaj teb cov peev txheej, suav nrog roj. Ib puag ncig thiab kev ua liaj ua teb tsim tau raug hem. Cov hnab yas tsis xav tau hauv cov teb ua rau kev ua liaj ua teb puas tsuaj, ua rau muaj kev puas tsuaj rau ecological.
Cov hnab yas yuav tsum raug txwv thoob ntiaj teb thiab hloov nrog cov khoom siv biodegradable rau tag nrho cov laj thawj no thiab cov hnab ntim cellophane yog lwm txoj hauv kev tsim nyog rau eco-friendly.
Qhov zoo ntawm Kev Siv Cellophane Hnab
Txawm hais tias kev tsim cov ntim cellulose yog qhov nyuaj, lub hnab cellulose muaj ntau yam txiaj ntsig ntawm cov hnab yas. Sib nrug los ntawm kev hloov pauv yas, cellophane muaj ntau yam txiaj ntsig ib puag ncig.
- Cellophane yog cov khoom lag luam ruaj khov ua los ntawm bio-based, cov peev txheej txuas ntxiv dua tshiab vim nws yog tsim los ntawm cellulose muab los ntawm cov nroj tsuag.Cellulose zaj duab xis ntim yog biodegradable.
- Uncoated cellulose ntim biodegrades ntawm 28-60 hnub, whereas coated ntim yuav siv sij hawm ntawm 80-120 hnub. Nws rhuav tshem hauv dej hauv 10 hnub, thiab yog tias nws coated, nws yuav siv li ib hlis.
- Cellophane tuaj yeem muab tso rau hauv tsev thiab tsis xav tau chaw ua lag luam.
- Cellophane yog pheej yig dua piv rau lwm yam khoom siv hauv ib puag ncig, uas yog cov khoom siv los ntawm kev lag luam ntawv.
- Biodegradable cellophane hnab yog noo noo thiab dej vapor resistant.
- Cellophane hnab yog qhov kev xaiv zoo rau khaws cov khoom noj. Cov hnab no zoo meej rau cov khoom ci, txiv ntoo, thiab lwm yam khoom oily.

Kev cuam tshuam ntawm Cellophane Hnab Decomposition ntawm Ib puag ncig
Cellophane, tseem hu ua cellulose, yog cov khoom siv hluavtaws ntawm cov hlua ntev ntawm cov piam thaj molecules uas decompose rau hauv cov suab thaj yooj yim. Nyob rau hauv cov av, cov molecules ua absorbable. Microorganisms nyob rau hauv cov av zom cov chains vim lawv pub rau cellulose.
Nyob rau hauv ib lub ntsiab lus, cellulose decomposes rau hauv qab zib molecules uas microorganisms nyob rau hauv cov av yuav tsuas haus thiab zom. Yog li ntawd, kev tawg ntawm cello hnab tsis muaj kev cuam tshuam rau ib puag ncig lossis biodiversity.
Cov txheej txheem aerobic decomposition no ua, txawm li cas los xij, tsim cov pa roj carbon dioxide, uas tuaj yeem rov ua dua tshiab thiab tsis xaus li cov khoom pov tseg. Tom qab tag nrho, carbon dioxide yog lub tsev cog khoom roj uas ua rau lub ntiaj teb sov sov.
