Yuav ua li cas yog iav fiber reinforced polymer (GFRP) composites tuaj yeem muab tso rau thaum kawg ntawm lawv lub neej muaj txiaj ntsig, ntxiv rau ntau xyoo ntawm cov txiaj ntsig pov thawj ntawm qhov hnyav txo, lub zog thiab nruj, corrosion kuj thiab kav ntev? Qhov ntawd, hauv qhov tseeb, yog qhov rov hais dua ntawm ABM Composite's thev naus laus zis.
Bioactive iav, siab zog fibers
Founded hauv 2014, Arctic Biomaterials Oy (Tampere, Finland) tau tsim cov iav fiber ntau biodegradable ua los ntawm lub npe hu ua bioactive iav, uas Ari Rosling, R&D tus thawj coj ntawm ABM Composite, piav qhia tias yog "kev tsim tshwj xeeb tsim hauv xyoo 1960s uas tso cai rau iav rau yuav degrade nyob rau hauv physiological tej yam kev mob. Thaum nkag mus rau hauv lub cev, lub khob tawg mus rau hauv nws cov ntxhia ntsev ntsev, tso cov sodium, magnesium, phosphates, thiab lwm yam, yog li tsim ib qho mob uas ua rau cov pob txha loj hlob. "
“Nws muaj cov khoom zoo sib xws raualkali-dawb iav fiber ntau (E-iav)” Rosling tau hais tias, "Tab sis lub iav bioactive no nyuaj rau kev tsim thiab kos rau hauv fibers, thiab txog tam sim no nws tsuas yog siv los ua hmoov lossis putty. Raws li peb paub, ABM Composite yog thawj lub tuam txhab ua kom muaj zog iav fiber ntau los ntawm nws ntawm kev lag luam nplai, thiab tam sim no peb tab tom siv cov ArcBiox X4/5 iav fibers los txhawb ntau hom yas, suav nrog biodegradable polymers ".
Kev kho mob implants
Lub cheeb tsam Tampere, ob teev sab qaum teb ntawm Helsinki, Finland, tau ua qhov chaw rau bio-based biodegradable polymers rau kev siv kho mob txij li xyoo 1980's. Rosling piav qhia tias, "Ib qho ntawm thawj cov khoom cog cog nrog cov ntaub ntawv no tau tsim nyob rau hauv Tampere, thiab qhov ntawd yog li cas ABM Composite tau pib! uas tam sim no yog peb chav ua lag luam kho mob ".
"Muaj ntau biodegradable, bioabsorbable polymers rau cog." Nws hais ntxiv tias, “tab sis lawv cov cuab yeej cuab tam nyob deb ntawm cov pob txha. Peb muaj peev xwm txhim kho cov biodegradable polymers thiaj li yuav muab cov implants tib lub zog raws li ntuj pob txha. " Rosling tau sau tseg tias qib kho mob ArcBiox iav fibers nrog qhov sib ntxiv ntawm ABM tuaj yeem txhim kho cov khoom siv ntawm biodegradable PLLA polymers los ntawm 200% mus rau 500%.
Raws li qhov tshwm sim, ABM Composite cov cog cog muaj kev ua tau zoo dua li cov cog cog nrog cov tsis muaj zog polymers, thaum tseem yog bioabsorbable thiab txhawb cov pob txha tsim thiab kev loj hlob. ABM Composite kuj tseem siv cov txheej txheem fiber ntau / strand qhov chaw los xyuas kom pom cov kev taw qhia fiber ntau, suav nrog kev tso cov fibers raws tag nrho qhov ntev ntawm qhov cog, nrog rau muab cov fibers ntxiv rau ntawm qhov chaw tsis muaj zog.
Kev siv tsev thiab kev siv tshuab
Nrog nws cov chaw lag luam kho mob loj hlob tuaj, ABM Composite lees paub tias bio-based thiab biodegradable polymers tuaj yeem siv rau hauv chav ua noj, tais diav thiab lwm yam khoom siv hauv tsev. "Cov biodegradable polymers feem ntau muaj cov khoom siv tsis zoo piv rau cov khoom siv roj av." Rosling tau hais tias, "Tab sis peb tuaj yeem txhawb nqa cov ntaub ntawv no nrog peb cov iav fiber ntau biodegradable, ua rau lawv zoo li lwm txoj hauv kev lag luam fossil-based plastics rau ntau yam kev siv".
Yog li ntawd, ABM Composite tau nce nws cov kev lag luam kev lag luam, uas tam sim no ntiav 60 tus neeg. "Peb muab cov kev daws teeb meem zoo tshaj plaws ntawm lub neej (EOL)." Rosling hais tias, "Peb qhov kev xav muaj txiaj ntsig yog muab cov biodegradable composites rau hauv kev lag luam composting uas lawv tig mus rau hauv av." Tsoos E-iav yog inert thiab yuav tsis degrade nyob rau hauv cov composting chaw.
ArcBiox Fiber Composites
ABM Composite tau tsim ntau hom ArcBiox X4/5 iav fibers rau kev siv sib xyaw, los ntawmluv-txiav fibersthiab txhaj tshuaj molding tebchaw rautsis tu ncua fibersrau cov txheej txheem xws li textile thiab pultrusion molding. ArcBiox BSGF ntau yam ua ke cov iav fiber ntau biodegradable nrog bio-based polyester resins thiab muaj nyob rau hauv cov qib kev siv tshuab thiab ArcBiox 5 qib pom zoo siv rau hauv daim ntawv thov kev sib cuag zaub mov.
ABM Composite kuj tau tshawb xyuas ntau yam biodegradable thiab bio-based polymers suav nrog Polylactic Acid (PLA), PLLA thiab Polybutylene Succinate (PBS). Daim duab hauv qab no qhia tau hais tias X4/5 iav fibers tuaj yeem txhim kho kev ua tau zoo los sib tw nrog cov qauv iav fiber reinforced polymers xws li polypropylene (PP) thiab txawm tias polyamide 6 (PA6).

Daim duab hauv qab no qhia tau hais tias X4/5 iav fibers tuaj yeem txhim kho kev ua tau zoo los sib tw nrog cov qauv iav fiber reinforced polymers xws li polypropylene (PP) thiab txawm tias polyamide 6 (PA6).
Durability & Compostability
Yog tias cov khoom sib xyaw no yog biodegradable, lawv yuav kav ntev npaum li cas? "Peb X4/5 iav fibers tsis yaj nyob rau hauv tsib feeb los yog ib hmos zoo li qab zib, thiab thaum lawv cov khoom yuav degrade lub sij hawm, nws yuav tsis pom zoo li." Rosling hais tias, "Yuav kom degrade zoo, peb xav tau qhov kub thiab av noo nyob rau lub sij hawm ntev, raws li pom nyob rau hauv vivo los yog nyob rau hauv industrial compost pawg. Piv txwv li, peb tau sim khob thiab tais ua los ntawm peb cov khoom siv ArcBiox BSGF, thiab lawv tuaj yeem tiv taus txog li 200 lub voj voog ntxuav tais diav yam tsis poob haujlwm. Muaj qee qhov kev puas tsuaj ntawm cov khoom siv kho tshuab, tab sis tsis yog mus rau qhov chaw uas lub khob tsis zoo siv. "
Txawm li cas los xij, nws yog ib qho tseem ceeb uas thaum cov khoom sib xyaw no tau muab pov tseg thaum kawg ntawm lawv lub neej muaj txiaj ntsig, lawv ua tau raws li cov qauv kev xav tau rau kev sib xyaw, thiab ABM Composite tau ua ntau yam kev sim los ua pov thawj tias nws ua tau raws li cov qauv no. "Raws li ISO cov qauv (rau kev tsim cov composting), biodegradation yuav tsum tshwm sim nyob rau hauv 6 lub hlis thiab decomposition nyob rau hauv 3 lub hlis / 90 hnub". Rosling hais tias, "Decomposition txhais tau tias tso cov qauv kuaj / cov khoom rau hauv biomass lossis compost. Tom qab 90 hnub, tus kws kho mob tshuaj xyuas biomass siv lub sieve. Tom qab 12 lub lis piam, tsawg kawg yog 90 feem pua ntawm cov khoom yuav tsum muaj peev xwm dhau los ntawm 2 hli × 2 hli sieve ".
Biodegradation yog txiav txim los ntawm kev sib tsoo cov khoom nkauj xwb rau hauv cov hmoov thiab ntsuas tag nrho cov nyiaj CO2 tso tawm tom qab 90 hnub. Qhov no ntsuas seb cov pa roj carbon ntau npaum li cas ntawm cov txheej txheem composting hloov mus rau hauv dej, biomass thiab CO2. "Yuav kom dhau qhov kev ntsuam xyuas kev lag luam composting, 90 feem pua ntawm cov theoretical 100 feem pua CO2 los ntawm cov txheej txheem composting yuav tsum ua tiav (raws li cov ntsiab lus carbon)".
Rosling hais tias ABM Composite tau ua tau raws li qhov xav tau ntawm decomposition thiab biodegradation, thiab cov kev sim tau pom tias qhov sib ntxiv ntawm nws cov X4 iav fiber ntau ua tau zoo dua biodegradability (saib cov lus saum toj no), uas tsuas yog 78% rau kev sib xyaw PLA tsis muaj zog, piv txwv li. Nws piav qhia, "Txawm li cas los xij, thaum peb 30% biodegradable iav fibers tau ntxiv, biodegradation tau nce mus rau 94%, thaum cov nqi degradation tseem zoo".
Raws li qhov tshwm sim, ABM Composite tau pom tias nws cov ntaub ntawv tuaj yeem raug lees paub tias yog compostable raws li EN 13432. Kev ntsuam xyuas tias nws cov ntaub ntawv tau dhau mus rau hnub no suav nrog ISO 14855-1 rau qhov kawg aerobic biodegradability ntawm cov ntaub ntawv raws li kev tswj cov composting, ISO 16929 rau aerobic TS ISO DIN EN 13432 Cov kev cai tshuaj lom neeg, thiab OECD 208 rau kev kuaj phytotoxicity, ISO DIN EN 13432.
CO2 tso tawm thaum lub sij hawm composting
Thaum lub sij hawm composting, CO2 raug tso tawm tiag tiag, tab sis qee qhov tseem nyob hauv av thiab tom qab ntawd siv los ntawm cov nroj tsuag. Composting tau kawm ntau xyoo lawm, ob qho tib si raws li cov txheej txheem kev lag luam thiab raws li cov txheej txheem tom qab composting uas tso tawm CO2 tsawg dua li lwm cov kev siv pov tseg pov tseg, thiab composting tseem suav hais tias yog ib puag ncig tus phooj ywg thiab carbon footprint txo cov txheej txheem.
Ecotoxicity suav nrog kev sim cov biomass uas tsim thaum lub sij hawm composting thiab cov nroj tsuag loj hlob nrog no biomass. "Qhov no yog kom paub tseeb tias composting cov khoom no tsis ua mob rau cov nroj tsuag loj hlob." Rosling hais. Tsis tas li ntawd, ABM Composite tau ua pov thawj tias nws cov ntaub ntawv ua tau raws li qhov yuav tsum tau ua ntawm biodegradation nyob rau hauv lub tsev composting tej yam kev mob, uas kuj yuav tsum tau 90% biodegradation, tab sis nyob rau hauv ib lub sij hawm 12 lub hlis, piv rau lub sij hawm luv luv rau industrial composting.
Cov ntawv thov kev lag luam, ntau lawm, cov nqi thiab kev loj hlob yav tom ntej
ABM Composite cov ntaub ntawv yog siv rau hauv ntau daim ntawv thov kev lag luam, tab sis ntau dua tsis tuaj yeem nthuav tawm vim muaj kev pom zoo tsis pub lwm tus paub. Rosling hais tias, "Peb xaj peb cov ntaub ntawv kom haum rau cov ntawv thov xws li khob, saucers, phaj, cutlery thiab cov thawv ntim khoom noj," Rosling hais tias, "tab sis lawv kuj tau siv los ua lwm yam khoom siv roj av hauv cov thawv kom zoo nkauj thiab cov khoom siv hauv tsev loj. Tsis ntev los no, peb cov ntaub ntawv tau raug xaiv los siv rau hauv kev tsim khoom ntawm cov khoom siv hauv kev lag luam loj uas yuav tsum tau hloov txhua 2-12 lub lis piam. Cov tuam txhab lag luam no tau lees paub tias los ntawm kev siv peb lub iav X4 iav fiber ntau, cov khoom siv tshuab no tuaj yeem ua nrog qhov yuav tsum tau hnav tsis kam thiab tseem tuaj yeem siv tau tom qab siv. Qhov no yog ib qho kev daws teeb meem zoo rau yav tom ntej vim tias cov tuam txhab no ntsib cov kev sib tw ntawm kev ua raws li cov cai tshiab ib puag ncig thiab CO2 emissions ".
Rosling hais ntxiv, "Tseem muaj kev txaus siab los siv peb cov fibers txuas ntxiv hauv ntau hom ntaub thiab nonwovens los ua cov khoom siv rau kev tsim kho kev lag luam. Peb kuj tseem pom kev txaus siab siv peb cov biodegradable fibers nrog bio-based tab sis tsis biodegradable PA lossis PP thiab inert thermoset cov ntaub ntawv ".
Tam sim no, X4/5 fiberglass yog kim dua E-iav, tab sis cov khoom ntim kuj tseem me me, thiab ABM Composite tab tom nrhiav ntau lub sijhawm los nthuav cov ntawv thov thiab pab txhawb kev nce mus txog 20,000 tonnes / xyoo raws li qhov xav tau loj hlob, uas tuaj yeem pab txo cov nqi. Txawm li cas los xij, Rosling hais tias ntau zaus cov nqi cuam tshuam nrog kev ua kom tau raws li kev ruaj ntseg thiab cov kev cai tshiab tsis tau txiav txim siab tag nrho. Lub caij no, qhov ceev ntawm kev txuag lub ntiaj teb yog loj hlob. "Lub koom haum twb thawb rau ntau cov khoom siv bio-based." Nws piav qhia, "Muaj ntau qhov kev txhawb siab los thawb cov thev naus laus zis rov ua dua tshiab, lub ntiaj teb yuav tsum tau txav nrawm dua ntawm qhov no thiab kuv xav tias tib neeg tsuas yog nce nws cov kev txhawb nqa rau bio-based khoom yav tom ntej".
LCA thiab Sustainability Advantage
Rosling hais tias ABM Composite cov ntaub ntawv txo cov pa hluav taws xob hauv tsev cog khoom thiab siv lub zog tsis txuas ntxiv los ntawm 50-60 feem pua ntawm ib kilogram. "Peb siv Environmental Footprint Database 2.0, kev lees paub GaBi dataset, thiab LCA (Life Cycle Analysis) suav rau peb cov khoom raws li cov txheej txheem teev tseg hauv ISO 14040 thiab ISO 14044".
"Tam sim no, thaum cov khoom sib txuas mus txog qhov kawg ntawm lawv lub neej voj voog, ntau lub zog yuav tsum tau ua kom muaj zog los yog pyrolyse cov khoom pov tseg thiab EOL, thiab cov khoom siv khib nyiab yog ib qho kev xaiv zoo nkauj, thiab nws yog ib qho ntawm cov ntsiab lus tseem ceeb uas peb muab, thiab peb tab tom muab hom tshiab ntawm kev rov ua dua tshiab. " Rosling hais tias, “Peb fiberglass yog tsim los ntawm tej yam ntuj tso minerals uas twb muaj nyob rau hauv cov av. Yog li vim li cas ho tsis compost EOL composite Cheebtsam, los yog dissolve fibers los ntawm non-degradable composites tom qab incineration thiab siv lawv ua fertiliser? Qhov no yog qhov kev xaiv rov ua dua tshiab ntawm kev txaus siab thoob ntiaj teb. "
