Txhua yam koj yuav tsum paub txog Cellulose Ntim
Yog tias koj tau saib mus rau hauv ib puag ncig-phooj ywg cov khoom ntim, muaj feem yuav yog koj tau hnov txog cellulose, tseem hu ua cellophane.
Cellophane yog ib yam khoom ntshiab, crinkly uas tau nyob ib puag ncig txij thaum xyoo 1900s.Tab sis, nws yuav ua rau koj xav tsis thoob thaum kawm tias cellophane, los yog cellulose film ntim, yog cov nroj tsuag, compostable, thiab cov khoom "ntsuab" tiag tiag.
Cellulose ntim yog dab tsi?
Pom nyob rau hauv 1833, cellulose yog ib yam khoom nyob rau hauv lub cell phab ntsa ntawm cov nroj tsuag.Nws yog tsim los ntawm ib tug ntev saw ntawm qabzib molecules, ua rau nws ib tug polysaccharide (lub sij hawm scientific rau carbohydrate).
Thaum ob peb cellulose chains ntawm hydrogen bond ua ke, lawv tsim ua ib yam dab tsi hu ua microfibrils, uas yog incredibly inflexible thiab tawv.Lub rigidity ntawm cov microfibrils no ua rau cellulose ib qho zoo heev molecule siv nyob rau hauv bioplastic ntau lawm.
Tsis tas li ntawd, cellulose yog cov biopolymer ntau tshaj plaws nyob rau hauv tag nrho lub ntiaj teb, thiab nws cov khoom muaj qhov cuam tshuam rau ib puag ncig tsawg.Txawm hais tias muaj ntau ntau hom cellulose.Cellulose ntim zaub mov feem ntau yog cellophane, ntshiab, nyias, biodegradable yas zoo li cov khoom.
Yuav ua li cas yog cellulose film ntim khoom?
Cellophane yog tsim los ntawm cellulose coj los ntawm paj rwb, ntoo, hemp, los yog lwm yam sustainably harvested natural sources.Nws pib raws li ib tug dawb dissolving pulp, uas yog 92% -98% cellulose.Tom qab ntawd, cov nqaij nyoos cellulose mus dhau plaub kauj ruam hauv qab no kom hloov mus rau hauv cellophane.
1. Cov cellulose yog yaj nyob rau hauv ib qho alkali (qhov yooj yim, ionic ntsev ntawm ib tug alkaline hlau tshuaj) thiab ces muaj hnub nyoog rau ob peb hnub.Cov txheej txheem dissolving no hu ua mercerization.
2. Carbon disulfide yog siv rau mercerized pulp los tsim cov tshuaj hu ua cellulose xanthate, los yog viscose.
3. Cov tshuaj no ces muab ntxiv rau ib tug sib tov ntawm sodium sulfate thiab dilute sulfuric acid.Qhov no hloov cov tshuaj rov qab rau hauv cellulose.
4. Tom qab ntawd, cov yeeb yaj kiab cellulose mus txog peb zaug ntxiv.Ua ntej kom tshem tawm cov sulfur, tom qab ntawd los ntxuav cov zaj duab xis, thiab thaum kawg ntxiv glycerin rau cov kav ntev.
Qhov kawg tshwm sim yog cellophane, uas yog siv nyob rau hauv kev lag luam ntim khoom noj, feem ntau los tsim biodegradable cellophane hnab los yog "cello hnab".
Dab tsi yog cov txiaj ntsig ntawm cov khoom siv cellulose?
Thaum cov txheej txheem tsim cov ntim cellulose nyuaj, cov txiaj ntsig tau pom tseeb.
Cov neeg Asmeskas siv 100 billion hnab yas txhua xyoo, xav tau 12 billion barrels roj txhua txhua xyoo.Ntxiv rau qhov ntawd, 100,000 tus tsiaj hauv hiav txwv raug tua los ntawm hnab yas txhua xyoo.Nws yuav siv sij hawm ntau tshaj 20 xyoo rau cov roj av-raws li cov hnab yas kom degrade hauv dej hiav txwv.Thaum lawv ua, lawv tsim micro-plastics uas nkag mus rau cov khoom noj khoom haus ntxiv.
Raws li peb lub zej zog loj hlob zoo ib puag ncig, peb tseem tab tom nrhiav rau eco-friendly, biodegradable lwm txoj rau roj av-raws li plastics.
Ib cag los ntawm kev ua lwm yam yas, cellulose zaj duab xis ntim nthuav qhia ntau yam txiaj ntsig ib puag ncig:
Sustainable & bio-based
Vim tias cellophane yog tsim los ntawm cellulose sau los ntawm cov nroj tsuag, nws yog cov khoom lag luam ruaj khov los ntawm cov khoom siv bio-raws li, txuas ntxiv mus.
Biodegradable
Cellulose zaj duab xis ntim yog biodegradable.Kev ntsuam xyuas tau pom tias cellulose ntim biodegrades hauv 28-60 hnub yog tias cov khoom tsis muaj coated thiab 80-120 hnub yog coated.Nws kuj degrades hauv dej hauv 10 hnub yog tias nws tsis coated thiab ib hlis twg yog tias nws coated.
Compostable
Cellophane kuj tseem muaj kev nyab xeeb los muab tso rau hauv koj cov pob zeb hauv tsev, thiab nws tsis tas yuav muaj chaw lag luam rau kev ua qoob loo.
Cov txiaj ntsig ntawm kev ntim khoom noj:
Tus nqi qis
Cellulose ntim tau nyob ib puag ncig txij li xyoo 1912, thiab nws yog ib qho khoom siv los ntawm kev lag luam ntawv.Piv nrog rau lwm cov khoom siv hauv eco-phooj ywg, cellophane muaj tus nqi qis.
Moisture-resistant
Biodegradable cellophane hnab tiv taus ya raws thiab dej vapor, ua rau lawv xaiv zoo heev rau kev nthuav tawm thiab khaws cov khoom noj.
Roj-resistant
Lawv ib txwm tiv taus cov roj thiab cov rog, yog li cov hnab cellophane zoo rau cov khoom ci, txiv ntseej, thiab lwm yam khoom noj roj.
Kub sealable
Cellophane yog cua sov sealable.Nrog rau cov cuab yeej tsim nyog, koj tuaj yeem ua kom sov thiab yooj yim ntim thiab tiv thaiv cov khoom noj uas khaws cia hauv hnab cellophane.
Lub neej yav tom ntej ntawm kev ntim cellulose yog dab tsi?
Lub neej yav tom ntej ntawmcellulose zaj duab xisntim zoo li ci.Daim ntawv tshaj tawm Kev Lag Luam Yav Tom Ntej tau kwv yees tias cov ntim ntim cellulose yuav muaj kev loj hlob txhua xyoo ntawm 4.9% ntawm 2018 thiab 2028.
Xya caum feem pua ntawm qhov kev loj hlob yuav tsum muaj nyob rau hauv cov khoom noj thiab dej haus.Biodegradable cellophane ntim zaj duab xis thiab lub hnab yog qhov siab tshaj plaws kev loj hlob qeb.
Cellophane thiab ntim khoom noj tsis yog tsuas yog kev lag luam cellulose siv xwb.Cellulose tau pom zoo los ntawm FDA rau kev siv hauv:
Khoom noj khoom haus additives
Kua muag dag
Tshuaj muab tshuaj
Kev kho mob
Cellophane tau pom ntau zaus hauv kev lag luam khoom noj thiab dej haus, tshuaj, kev saib xyuas tus kheej, kev saib xyuas hauv tsev, thiab cov khw muag khoom.
Cov khoom ntim cellulose puas yog rau kuv lub lag luam?
Yog tias koj tam sim no siv cov hnab yas rau cov khoom qab zib, txiv ntoo, cov khoom ci, thiab lwm yam, cov hnab ntim cellophane yog lwm txoj hauv kev zoo tshaj.Ua los ntawm cov resin hu ua NatureFlex ™ ua los ntawm cellulose muab los ntawm cov ntoo pulp, peb lub hnab muaj zog, crystal ntshiab thiab muaj ntawv pov thawj compostable.
