Ntuj Biological Round Boxes Ntawm Chocolates Yuav Ib puag ncig phooj ywg mus txog thaum kawg

Natural biological Round Boxes Ntawm Chocolates yuav ua rau ib puag ncig tus phooj ywg mus txog thaum kawg

Nyob rau hauv lub neej yav tom ntej, tej yam ntuj tso ntim cov ntaub ntawv yuav txhim khu kev qha thiab innovate nyob rau hauv kev txhawb nqa ntawm science thiab technology, maj mam zoo meej nyob rau hauv lub tsis paub tab, los yog yuav nyob rau hauv ib tug txiav txim lub lag luam feem ntau nyob rau hauv lub ntim kev lag luam.

Nyob rau hauv xyoo tas los no, kev tshawb fawb thiab kev loj hlob ntawm cov yas degradable thiab cov khoom siv roj ntsha tau txhawb kev loj hlob ntawm kev lag luam ntim khoom thoob ntiaj teb thiab dhau los ua cov kev xaiv ntawm cov tuam txhab ntim khoom. Txawm li cas los xij, cov plastics degraded lawv tus kheej degrade qeeb hauv cov av thiab tsis tuaj yeem rov ua dua tshiab raws sijhawm. Nws tsis tuaj yeem degraded tag nrho, thiab yuav muaj qhov tsis zoo xws li pom cov stains, uas ua rau nws daim ntawv thov kev cia siab tsawg. Yog li ntawd, cov khoom ntim khoom siv roj ntsha tau dhau los ua ib qho ntawm cov khoom ntim muaj peev xwm tshaj plaws nrog qhov zoo ntawm kev tiv thaiv ib puag ncig.

Cog fiber ntau ntim khoom

Lub ntuj tsim ntawm cov khoom ntim fiber ntau yog ntau tshaj 80 feem pua, thiab cov khoom tsim los ntawm lawv tuaj yeem raug degraded ib txwm txawm tias lawv raug tso tseg nyob rau hauv ib puag ncig ntuj tom qab siv. Tsis tas li ntawd, cov nroj tsuag ntim ntim kuj muaj cov yam ntxwv ntawm lub zog siab, qhov ntuj ceeb tsheej, yog li lawv tau nyiam tshwj xeeb hauv kev ntim khoom.

Daim ntawv thov ntawm cov nroj tsuag fiber ntau hauv cov ntaub ntawv ntim feem ntau suav nrog ob hom khoom sib xyaw, uas yog, cov khoom siv fiber ntau thiab cov hmoov txhuv nplej siab, cov khoom cog fiber ntau thiab cov khoom siv polymer. Cov qauv tshuaj ntawm cov nroj tsuag fiber ntau thiab cov hmoov txhuv nplej siab zoo ib yam, thiab ob qho tib si muaj kev sib raug zoo. Cov cuab yeej muaj peev xwm, dej tsis kam thiab thermal stability ntawm cov hmoov txhuv nplej siab yuav ua tau zoo dua tom qab kev hloov tshuaj lom neeg ntawm ob qho tib si thiab cov tshuaj tiv thaiv kab mob sib kis raws li cov txheej txheem tshwj xeeb. Ntxiv qhov tsim nyog ntawm cov nroj tsuag fiber ntau rau polymers xws li yas tuaj yeem txhim kho degradability thiab ib puag ncig tus phooj ywg ntawm cov ntaub ntawv. Tab sis muaj ntau qhov sib txawv ntawm cov nroj tsuag fiber ntau thiab polymer nyob rau hauv qhov xwm txheej, yog li nws yog ib qho tsim nyog los hloov cov nroj tsuag fiber ntau los ntawm kev siv lub cev los yog tshuaj, thiab tom qab ntawd ua ke nrog cov molecules polymer.

Nyob rau hauv kev pom ntawm qhov zoo ntawm cov nroj tsuag fiber ntim cov ntaub ntawv, muaj ntau yam kev tshawb fawb nyob rau hauv daim teb no. Wageningen Agricultural University hauv Netherlands tau tsim cov yas biodegradable, petrochemical tsis pub siv cov nplej, pob kws thiab qos yaj ywm starch thiab ntxiv hemp fibers kom nws muaj zog. Cov yas tuaj yeem siv rau hauv cov txheej ntim khoom, cov khoom ntim khoom noj, cov hnab ntim khoom, cov hnab ntim khoom thiab cov yeeb yaj kiab ua liaj ua teb. Lub straw board ua los ntawm cov straw ua tau zoo thermal rwb thaiv tsev, rwb thaiv tsev kub, txuag hluav taws xob thiab lwm yam dej num, zoo huab cua permeability, muaj zog muaj zog, thiab muab piv nrog cov khoom siv tsoos, muaj zog waterproof thiab seismic zog. Tsis tas li ntawd, straw board siv los ua cov khoom ntim, nws chav tsev loj tsuas yog 1/10 ntawm tib lub ntim ntawm cov khoom siv duab los qhia. Nyob rau hauv xyoo tas los no, cov kws tshawb fawb hauv tsev tau tsim cov khoom siv tshwj xeeb pov tseg cov tais diav nrog straw pulp ua cov khoom siv tseem ceeb, uas muaj cov dej kub ua haujlwm, tsis muaj dej, tsis muaj delamination, roj kuj thiab kub sealing, thiab tuaj yeem siv los tsim cov ntawv sau. tom qab rov ua dua. Nrog mugwort hmoov thiab additives sib xyaw ua tiav ntawm lub hnab zaj duab xis, nrog cov kab mob tua kab mob, mildew, kab thiab tshuaj ua haujlwm, nws kuj tuaj yeem ntxuav thiab siv ntau zaus.

Cov nroj tsuag fiber ntau muaj ntau qhov chaw thiab tus nqi qis, uas ua lub luag haujlwm tseem ceeb hauv kev txhim kho thiab kev tshawb fawb ntawm cov khoom ntim khoom siv roj ntsha. Raws li cov yam ntxwv ntawm cov nroj tsuag fiber ntau, kev txhim kho yav tom ntej thiab daim ntawv thov yuav raug cuam tshuam los ntawm peb yam hauv qab no.

1. Ntxiv txhim kho cov dej tsis kam ntawm cov nroj tsuag fibers. Cov nroj tsuag fiber ntau muaj ntau pawg hydroxyl thiab muaj zog hydrophilicity. Txhawm rau txhim kho cov dej tsis kam ntawm cov nroj tsuag fiber ntau, nws yog qhov yuav tsum tau hloov kho kom tsim nyog.

2. Txuas ntxiv txhim kho cov txheej txheem tsim khoom tsis muaj kuab lom. Kev kho cov nroj tsuag fiber ntau nrog lye yog txoj kev hloov kho tshiab tshaj plaws los txhim kho nws txoj kev khi lub zog nrog lwm cov ntaub ntawv, tab sis vim tias feem ntau cov txheej txheem yuav tsum tau ntxuav cov nroj tsuag fiber ntau, nws yuav ua rau muaj kuab paug hauv cov txheej txheem. Tam sim no qhov tseeb cog fiber ntau txoj kev kho mob -- chav blasting kev kho mob, yog ib tug tsis muaj kuab paug cog fiber ntau hloov txoj kev, muaj ib tug zoo daim ntawv thov kev cia siab.

3. Txo cov nqi tsim khoom ntawm cov nroj tsuag cellulose composite nrog rau lwm cov ntaub ntawv, thiaj li los txhim kho kev sib tw ntawm cov nroj tsuag fiber ntau hauv kev ua lag luam.

Nyob rau hauv xyoo tas los no, vim tib neeg kev tsim khoom thiab kev ua neej nyob, cov khoom yas uas tsis tuaj yeem raug degraded tau ua rau muaj kuab paug dawb loj, uas tau ua rau muaj kev kub ntxhov rau ntiaj teb ib puag ncig. Tsis tas li ntawd, lub ntiaj teb cov peev txheej roj tau nce zuj zus, muab lub sijhawm zoo rau kev txhim kho thiab siv cov khoom siv biodegradable. Nyob rau hauv lub neej yav tom ntej, tej yam ntuj tso ntim cov ntaub ntawv yuav txhim khu kev qha thiab innovate nyob rau hauv kev txhawb nqa ntawm science thiab technology, maj mam zoo meej nyob rau hauv lub tsis paub tab, los yog yuav nyob rau hauv ib tug txiav txim lub lag luam feem ntau nyob rau hauv lub ntim kev lag luam.

Cov khoom ntim cov hmoov txhuv nplej siab

Cov hmoov txhuv nplej siab yog ib qho polysaccharide ntau heev, yog cov khoom ntawm cov nroj tsuag photosynthesis, xws li cereal starch, qos starch, taum starch thiab lwm yam starches ntau tshaj 100. Raws li ib tug natural biological ntim khoom, starch ntim khoom muaj ib tug xov tooj ntawm daim ntawv thov zoo, xws li: ( 1) yuav tsis ua paug ib puag ncig; (2) Vim tias nws yog cov khoom siv txuas ntxiv dua tshiab, nws yuav tsis ntsib qhov kev hem thawj ntawm kev tsis muaj zog; ③ Nws tuaj yeem hloov qee cov ntaub ntawv ntim khoom polymeric, tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov ntawm cov khoom ntim khoom noj tau ua qee qhov kev ua tiav. Yog lawm, txhawm rau ua kom tau raws li qhov xav tau ntawm kev lag luam ntau lawm, peb kuj yuav tsum siv cov tshuaj los yog lub cev los kho cov hmoov txhuv nplej siab, txhawm rau txhawm rau kov yeej nws qhov tsis muaj dej txias solubility, tsis zoo khov-thaw stability thiab lwm yam khoom ntawm qhov tsis xws luag. , yog li txhawm rau txhim kho nws cov khoom qub lossis txawm nce cov khoom tshiab. Nyob rau hauv xyoo tas los no, cov kws tshawb fawb tau sib xyaw cov hmoov txhuv nplej siab nrog polyhydrocarbobutyrate (PHB), polylactic acid (PLA) thiab lwm cov ntaub ntawv polymer uas tuaj yeem degradable los ua cov khoom ntim khoom sib xyaw, uas txo cov nqi ntawm cov ntaub ntawv ntim khoom.

Tam sim no, cov khoom ntim cov hmoov txhuv nplej siab tseem ceeb siv hauv kev lag luam muaj xws li hloov cov hmoov txhuv nplej siab, cov khoom siv hmoov txhuv nplej siab, cov hmoov txhuv nplej siab thiab lwm yam. Cov hmoov txhuv nplej siab raws li bioplastics kuj tau siv dav, raws li kev kwv yees tsis tiav, nws cov khoom lag luam txhua xyoo tau tshaj 25,000 tons, ntau dua 75 feem pua ​​​​ntawm cov khoom siv hauv kev lag luam ntim khoom, cov khoom tseem ceeb yog ntim yas, ntim hnab , ntim zaj duab xis thiab lwm yam. Nws tuaj yeem hais tau tias cov hmoov txhuv nplej siab raws li bioplastics tau dhau los ua lwm txoj hauv kev rau cov khoom ntim khoom noj.
