Degradable plastics tau dhau los ua lub ntsiab lus kub hauv kev tiv thaiv ib puag ncig nyob rau xyoo tsis ntev los no, thiab muaj tshwj xeeb tshaj plaws hauv kev tawm khoom xws liPov Tseg rau -} mus ntim, biodegradable rau - mus ntim, thiabrov ua dua rau -} mus ntimCov. Txawm li cas los xij, muaj ntau ntau qhov kev nkag siab tsis meej hauv kev ua lag luam, ua rau tsis meej pem hauv kev ua haujlwm thiab cov neeg siv khoom. Cia peb saib ntawm tsib tus neeg tsis paub meej los pab qhia meej qhov teeb meem no.
Myth 1: Txwv tsis ncaj txhais tau tias nws tuaj yeem ua rau txhua qhov chaw
Coob tus neeg ntseeg tias degradable plastics yuav decompose sai, tsis hais qhov twg lawv raug pov tseg. Qhov no tsis muaj tseeb. Uncradation yuav tsum muaj cov xwm txheej tshwj xeeb; Txwv tsis pub, lawv yuav nyob twj ywm tsis hloov rau xyoo.
Kev tsis haum yuav tsis tas muaj nyob rau hauv lub ntuj ib puag ncig
Piv txwv li, qee cov biodegradable rau - Mus ntim yuav tsum muaj kev sib txuam kub, av noo, thiab cov kab mob av noo kom lwj. Yog hais tias ncaj qha pov tseg hauv av lossis dej, lawv yuav nyob ntawd rau xyoo. Qhov no tseem pom tias tsis ua tib zoo pov tseg rau pov tseg rau kev pov tseg rau- mus ntim tsis ploj tam sim ntawd thiab tseem muaj kev cuam tshuam rau ib puag ncig.
Muaj Nplooj Ntawv Sib Tw Los Ntawm Neeg Pov Tseg
Ntau lub biodegradable rau - mus ntim yog tsim los siv rau hauv "kev kub siab tuaj yeem ncav cuag ntau dua 50 qib thiab ib puag ncig yog qhov zoo rau kev txiav txim siab. Txawm li cas los xij, nyob rau hauv tsev neeg cov kaus poom, cov xwm txheej tsis txaus, ua kev txiav txim nyuaj. Yog li, cov tuam txhab yuav tsum tau piav meej meej txog kev siv lawv cov khoom thaum txhawb nqa lawv, txwv tsis pub lawv tuaj yeem ua tsis tau cov neeg siv khoom.
Kev ua rau muaj kev cuam tshuam ntau dua hauv cov chaw sib txawv
Nyob rau hauv ib nplooj lwg Yog li ntawd, qhov kev ua tau zoo txawv nyob hauv ib puag ncig sib txawv, thiab kev tsis tuaj yeem ua.
Hyth 2: biodegradable plastics yog tas rau ib qho tsim nyog ib puag ncig phooj ywg zoo li ib txwm muaj
Coob leej ntau tus ntseeg tias "biodegradable" sib npaug ib puag ncig phooj ywg. Qhov tseeb, kev tiv thaiv ib puag ncig yog nyob ntawm tag nrho cov txheej txheem, tsis yog ib qho khoom siv xwb.
Cov txheej txheem ntau lawm kuj noj ntau cov peev txheej
Txawm hais tias biodegradable rau - nyem fiber ntau, xws li cov khoom lag luam nplej thiab kev ua haujlwm xav tau ntau lub zog thiab lub zog, thiab tseem tsim cov pa pa roj carbon monissions. Hauv qee kis, lub zog siv ntawm kev tsim cov khoom lag luam no cov khoom siv tau siab dua li ntawm cov yas zoo tib yam.
Kev tiv thaiv ib puag ncig muaj tus nqi, tab sis nws muaj kev txwv
Biodegradable rau -} mus ntim tuaj yeem yog tus nqi ntev, thiab muaj tus nqi nplua nuj, thiab muaj kev cuam tshuam tshwj xeeb, thiab muaj kev cuam tshuam tshwj xeeb, thiab muaj kev ua kom zoo dua, thiab muaj cov kev ua kom rov qab ua rau muaj kev cuam tshuam. Yog li ntawd, lawv tsuas yog ua ib feem ntawm kev daws teeb meem ib puag ncig, tsis yog cov lus teb nkaus xwb.
Saib ntawm tag nrho lub neej
Seb lub npov noj su yog ib puag ncig ua phooj ywg nyob ntawm tag nrho cov txheej txheem, los ntawm kev tsim khoom, tsheb thauj mus los, kom pov tseg. Txawm hais tias rov ua dua tshiab rau - mus ntim tuaj yeem yog qhov tsis zoo yog tias lawv tau thauj dhau qhov kev ncua deb lossis muaj qhov ua kom dhau los. Yog li, kev tiv thaiv ib puag ncig yuav tsum raug txiav txim siab thoob plaws tag nrho cov khoom siv, tsis yog los ntawm seb lawv puas yog "biodegradable."
MYTH 3: Untradable plastics yeej ib txwm siv rov ua tau
"Cuam tshuam" thiab "rov ua dua" yog ob yam sib txawv; Tsis txhob yuam kev lawv.
Ntsim tsis tau ≠ rov ua dua tshiab
Rov qab siv rau -}} mus ntim, xws li cov tsiaj pwj lossis pp su noj su, yog rov ua dua tshiab thiab rov siv tau. Biodegradable rau - mus ntim yog degraded los ntawm cov kab mob me. Sib tov ob qho ua ke tuaj yeem ua rau muaj peev xwm ua kom tag nrho cov khoom siv rov qab ua tiav.
Cov txheej txheem rov ua dua tshiab
Rov qab siv rau -} mus ntim yuav tsum ua kom tau raws li cov qauv cog qoob loo ua ntej lawv tuaj yeem siv. Sib tov biodegradable rau - mus ntim yuav puas cov khoom siv rov ua dua tshiab thiab txo nws cov khoom zoo. Yog li ntawd, ob hom ntim yuav tsum tsis txhob sib xyaw.
Sib xyaw ua dua tshiab tuaj yeem ua teeb meem
Yog tias cov neeg siv khoom tsis tuaj yeem paub qhov txawv ntawm ob thiab pov tseg rau -}} Cov nroj tsuag yuav tsum tau muab pov tseg tag nrho, cov khoom siv khib nyiab thiab nce zuj zus. Yog li, cov tuam txhab yuav tsum tau sau kom meej rau lawv cov khoom lag luam, thiab cov neeg siv khoom yuav tsum kawm paub kom zoo li cas.
HYTH 4: Txhua lub biodegradable plastics muaj tib yam khoom
Muaj ntau hom biodegradable plastics, thiab lawv cov kev ua tau txawv, yog li nws nyuaj rau dav dav.
Qhov sib txawv ntawm cov ntaub ntawv
PLA muaj feem ntau siv nyob rau hauv cov khob pob tshab thiab thawv, tab sis nws muaj cov cua sov tsis zoo. PBAT yog hloov tau thiab haum rau lub hnab. Starch - Cov ntaub ntawv txwv tsis txaus sai tab sis muaj ntau rau deformation. Cov ntaub ntawv sib txawv txiav txim siab lawv cov kev haum rau cov xwm txheej sib txawv.
Cov tshav kub sib txawv tiv taus, txias kuj, thiab cov khoom sib khi
Ntau lub biodegradable rau - mus ntim tsis yog cua sov- tiv taus thaum muaj kua zaub kub lossis microwaved. PLA ua tau cittle nyob rau hauv ib puag ncig txias, thaum PBat muaj kev rov qab ntau dua. Yog li ntawd, thaum xaiv cov thawv su, cov tuam txhab yuav tsum xav txog lawv cov kev xav tau tshwj xeeb ntau dua li siv cov kev xaiv random.
Kev Kawm Tiag Tiag
Qee cov kas fes siv rau lawv khob, tab sis thaum cov qhua tuaj haus dej haus rau lawv, lub khob deformed, yuam lawv rov qab mus rau cov ntaub ntawv ib txwm. Txawm li cas los xij, PLA ua haujlwm zoo rau cov dej txias txias. Qhov no qhia tau tias sib txawv biodegradable rau- Puas muaj cov ntawv thov tshwj xeeb thiab tsis yog ib qho {} {5- txhua txoj hauv kev.
HYTH 5: Siv biodegradable plastics sib txuas ntsuab hloov
Kev tiv thaiv ib puag ncig tsis yog hais txog kev hloov ib qho khoom siv; Nws yuav tsum muaj cov kev ua kom ze.
Kev lag luam yuav tsum muaj cov tswv yim zoo
Cias hloov mus rau - nyem mus ntim tsis lees tias muaj kev tiv thaiv ib puag ncig. Cov tuam txhab yuav tsum xav txog kev siv hluav taws xob ntau dua, kev tsheb thauj mus los, khib nyiab pov tseg, thiab txawm tias muab saw hlau muab khoom. Yog tsis muaj cov kev hloov pauv no, qhov kev cuam tshuam yuav txwv.
Kev ntsuas kev siv cov khoom sib txawv
Hauv qee qhov xwm txheej, cov rov ua dua tshiab yog qhov tsim nyog dua li biodegradables. Piv txwv li, rau ntev {- deb cov khoom xa tuaj, siv ruaj ruaj, cov thawv ntim khoom siv tau tuaj yeem txo cov khib nyiab. Kev lag luam yuav tsum txiav txim siab lawv cov kev xav tau tshwj xeeb dua li qhov tsis pom kev "tag nrho cov biodegradability."
Cov cai tswjfwm thiab cov neeg siv khoom kawm yog qhov tseem ceeb
Cov chaw sib txawv muaj sib txawv rau biodegradable rau biodegradable rau -}}}}}}}} Cov qauv sib txawv hauv Tebchaws Europe thiab Tebchaws Asmeskas. Cov tuam txhab yuav tsum ua kom tau raws li cov kev cai ntawm lawv lub hom phiaj. Tib lub sijhawm, cov neeg siv khoom yuav tsum tau nkag siab txog kev siv thiab pov tseg kom meej meej tias kev tiv thaiv ib puag ncig yog qhov pom tseeb.
Tag
Degradable plastics Ua si lub luag haujlwm tseem ceeb hauv biodegradable thiab rov ua dua rau -}} Taug kev thawv, tab sis lawv tsis yog panacea. Kev tiv thaiv ib puag ncig tiag yuav tsum muaj kev ua kom muaj kev sib txawv ntawm cov khoom siv, rov siv dua tshiab, thiab cov cai tswj.
Yangrui muaj cov lag luam muaj ntau txoj kev daws teeb meem hauv qhov no. Lub tuam txhab tuav cov ntawv pov thawj thoob ntiaj teb xws li ISO thiab FDA los xyuas kom muaj kev nyab xeeb zaub mov. Nws tseem muaj cov peev txheej ntau lawm thiab cov kev pabcuam tsim tau los pab cov neeg txo cov kev cai, thiab txhim kho lawv cov duab hom thiab kev sib tw ua lag luam.
Qhov twg yuav tau yuav khoom rau - mus ntim?
Yog tias koj tab tom nrhiav rau cov neeg xa khoom kom txhim khu kev qha ntawm cov thawv ntim khoom noj uas pov tseg, huizhou yangrui printing & ntim khoom Co., Ltd. yog koj tus khub zoo. Nrog dhau ib xyoo caum ntawm cov kev paub ntau lawm, peb cov kab khoom lag luam suav nrog kev pov tseg, thiab rov ua dua tshiab} kev tsim qauv thiab cov qauv kev yuav khoom.
