Khalase ea bioactive, likhoele tse matla haholo
E Thehiloe ka 2014, Arctic Biomaterials Oy (Tampere, Finland) e hlahisitse fiber ea khalase e ka senyehang e entsoeng ka seo ho thoeng ke khalase ea bioactive, eo Ari Rosling, mookameli oa R&D ho ABM Composite, a e hlalosang e le "tlhahiso e khethehileng e entsoeng lilemong tsa bo-1960 e lumellang khalase ho ho nyenyefatsa tlasa maemo a fisioloji. Ha e kenngoa ’meleng, khalase e oela ka har’a metsoako ea eona ea letsoai la letsoai, e ntša sodium, magnesium, phosphates, joalo-joalo, kahoo e baka boemo bo etsang hore masapo a hōle.”
"E na le thepa e tšoanang lefiber ea khalase e se nang alkali (E-glass).” Rosling o itse, "Empa khalase ena ea bioactive ho thata ho e etsa le ho e hula ka har'a likhoele, 'me ho fihlela joale e ntse e sebelisoa feela e le phofo kapa putty. Ho ea kamoo re tsebang kateng, ABM Composite e ne e le k'hamphani ea pele ea ho etsa likhoele tsa khalase tse matla haholo ho tloha ho eona ka tekanyo ea indasteri, 'me hona joale re sebelisa likhoele tsena tsa khalase tsa ArcBiox X4/5 ho matlafatsa mefuta e sa tšoaneng ea lipolasetiki, ho kenyelletsa le li-polymers tse senyehang.
Li-implants tsa bongaka
Sebaka sa Tampere, lihora tse peli ka leboea ho Helsinki, Finland, esale e le setsi sa li-polymers tsa biodegradable bakeng sa lits'ebetso tsa bongaka ho tloha ka bo-1980. Rosling oa hlalosa, “E 'ngoe ea li-implant tsa pele tse fumanehang khoebong tse entsoeng ka thepa ena e ile ea hlahisoa Tampere, 'me ke kamoo ABM Composite e qalileng kateng! eo hona joale e leng lekala la rona la khoebo ea bongaka”.
"Ho na le li-polymer tse ngata tse ka senyehang, tse ka monyehang bakeng sa li-implants." O tsoela pele, “empa matla a tsona a tšebetso a hole le masapo a tlhaho. Re khonne ho ntlafatsa li-polymer tsena tse ka senyehang e le ho fa sejalo matla a tšoanang le a lesapo la tlhaho ”. Rosling o hlokometse hore likhoele tsa khalase tsa ArcBiox tsa boemo ba bongaka ka tlatsetso ea ABM li ka ntlafatsa thepa ea mochini oa li-polymers tsa biodegradable PLLA ka 200% ho isa ho 500%.
Ka lebaka leo, li-implants tsa ABM Composite li fana ka ts'ebetso e phahameng ho feta li-implants tse entsoeng ka li-polymers tse sa matlafatsoang, ha li ntse li le bioabsorbable le ho khothalletsa ho thehoa le ho hōla ha masapo. ABM Composite e boetse e sebelisa mekhoa ea ho beha li-fibre / strand ho etsa bonnete ba hore ho na le mekhoa e metle ea fiber, ho kenyelletsa le ho beha likhoele ka bolelele bohle ba ho kenngoa, hammoho le ho beha likhoele tse eketsehileng libakeng tse ka bang fokola.

Ka yuniti ea eona e ntseng e hola ea khoebo ea bongaka, ABM Composite e hlokomela hore li-polymers tse thehiloeng ho bio-le-biodegradable le tsona li ka sebelisoa bakeng sa lisebelisoa tsa kichine, li-cutlery le lintho tse ling tsa ntlo. "Li-polymer tsena tse senyehang habonolo ha li na thepa e sebetsang hantle ha li bapisoa le lipolasetiki tse entsoeng ka peterole." Rosling o itse, "Empa re ka matlafatsa lisebelisoa tsena ka likhoele tsa rona tsa khalase tse senyehang habonolo, ra li etsa sebaka se setle ho fapana le lipolasetiki tsa khoebo tse thehiloeng ka mesaletsa ea lintho tsa khale bakeng sa lits'ebetso tse fapaneng tsa tekheniki".
Ka lebaka leo, ABM Composite e ekelitse yuniti ea eona ea khoebo ea tekheniki, eo hona joale e hirang batho ba 60. "Re fana ka tharollo e tsitsitseng ea ho qetela ea bophelo (EOL)." Rosling o re, "Molemo oa rona oa bohlokoa ke ho kenya metsoako ena e ka senyehang habonolo tšebetsong ea manyolo a indasteri moo e fetohang mobu." Traditional E-glass ha e sebetse 'me e ke ke ea nyenyefatsa litsing tsena tsa manyolo.
ArcBiox Fiber Composites
ABM Composite e hlahisitse mefuta e fapaneng ea likhoele tsa khalase tsa ArcBiox X4/5 bakeng sa lisebelisoa tse kopaneng, ho tlohalikhoele tse khaotsoengle metsoako ea ho etsa ente holikhoele tse tsoelang pelebakeng sa lits'ebetso tse kang ho bopa masela le pultrusion. Mofuta oa ArcBiox BSGF o kopanya likhoele tsa khalase tse senyehang ka tlhaho le li-resin tsa polyester tse thehiloeng ho bio, 'me li fumaneha ka limaraka tse akaretsang tsa theknoloji le limaraka tsa ArcBiox 5 tse lumelletsoeng ho sebelisoa lits'ebetsong tsa ho ikopanya le lijo.

Ho tšoarella le Motsoako
Haeba metsoako ee e khona ho bola, e tla tšoarella nako e kae? "Lithapo tsa rona tsa khalase tsa X4/5 ha li qhibilihe ka metsotso e mehlano kapa bosiu bo le bong joalo ka ha tsoekere e etsa, 'me le ha thepa ea bona e tla senyeha ha nako e ntse e ea, e ke ke ea bonahala." Rosling o re, "Ho theola boemo ka katleho, re hloka mocheso o phahameng le mongobo ka nako e telele, joalo ka ha li fumanoa ka har'a vivo kapa liqubung tsa manyolo a liindasteri. Mohlala, re ile ra leka likopi le likotlolo tse entsoeng ka thepa ea rona ea ArcBiox BSGF, 'me li ne li khona ho mamella lipotoloho tse 200 tsa ho hlatsoa lijana ntle le ho lahleheloa ke ts'ebetso. Ho na le ho senyeha ho itseng ha thepa ea mochine, empa eseng moo likopi li sa bolokehang ho sebelisoa ”.
Leha ho le joalo, ho bohlokoa hore ha metsoako ena e lahloa qetellong ea bophelo ba eona ba bohlokoa, e fihlelle litlhoko tse tloaelehileng tse hlokahalang bakeng sa manyolo, 'me ABM Composite e entse letoto la liteko ho paka hore e fihlela litekanyetso tsena. "Ho ea ka litekanyetso tsa ISO (bakeng sa manyolo a indasteri), biodegradation e lokela ho etsahala nakong ea likhoeli tse 6 le ho bola nakong ea likhoeli tse 3 / matsatsi a 90". Rosling o re, "Ho bola ho bolela ho beha sampole/sehlahisoa sa liteko ka har'a biomass kapa manyolo. ka mor'a matsatsi a 90, setsebi se hlahloba biomass se sebelisa sefe. ka mor'a libeke tse 12, bonyane karolo ea 90 lekholong ea sehlahisoa e lokela ho khona ho feta ka sefeng sa 2 mm × 2 mm".
Biodegradation e khethoa ka ho sila lisebelisoa tsa moroetsana hore e be phofo le ho lekanya kakaretso ea CO2 e lokolloa ka mor'a matsatsi a 90. Sena se lekola hore na ke bokae ba khabone ea tšebetso ea manyolo e fetoloang metsi, biomass le CO2. "Ho fetisa tlhahlobo ea manyolo ka liindasteri, karolo ea 90 lekholong ea theoretical 100 per cent CO2 ho tloha ts'ebetsong ea manyolo e tlameha ho finyelloa (ho ipapisitse le carbon content)".
Rosling o re ABM Composite e fihletse litlhoko tsa ho bola le ho senyeha ha lintho tse phelang, 'me liteko li bontšitse hore ho eketsoa ha fiber ea eona ea khalase ea X4 e hlile e ntlafatsa biodegradability (sheba tafole e ka holimo), e leng 78% feela bakeng sa motsoako o sa tiisetsoang oa PLA, mohlala. Oa hlalosa, "Leha ho le joalo, ha likhalase tsa rona tsa 30% tsa likhalase tse senyehang li kenngoa, biodegradation e ile ea eketseha ho 94%, ha litekanyetso tsa ho senyeha li ntse li le ntle".
Ka lebaka leo, ABM Composite e bontšitse hore thepa ea eona e ka netefatsoa e le manyolo ho latela EN 13432. Liteko tseo thepa ea eona e seng e fetile ho fihlela joale li kenyelletsa ISO 14855-1 bakeng sa biodegradability ea ho qetela ea aerobic ea thepa tlas'a maemo a laoloang a manyolo, ISO 16929 bakeng sa aerobics. ho bola ho laoloang, ISO DIN EN 13432 bakeng sa litlhoko tsa lik'hemik'hale, le OECD 208 bakeng sa tlhahlobo ea phytotoxicity, ISO DIN EN 13432.

Nakong ea composting, CO2 e hlile e lokolloa, empa e meng e sala mobung ebe e sebelisoa ke limela.

"Sena ke ho etsa bonnete ba hore manyolo a lihlahisoa tsena ha a lematse limela tse ntseng li hola." Ho boletse Rosling. Ho phaella moo, ABM Composite e bontšitse hore thepa ea eona e finyella litlhoko tsa ho senyeha ha limela tlas'a maemo a manyolo a malapeng, ao hape a hlokang 90% ea ho senyeha ha limela, empa ka nako ea likhoeli tse 12, ha ho bapisoa le nako e khutšoanyane ea manyolo a indasteri.

Lisebelisoa tsa ABM Composite li sebelisoa lits'ebetsong tse ngata tsa khoebo, empa tse ling li ke ke tsa senoloa ka lebaka la litumellano tsa lekunutu. Rosling o re: “Re odara thepa ea rōna hore e lumellane le lintho tse sebelisoang tse kang likomiki, li-sauers, lipoleiti, lijana le lijana tsa ho boloka lijo, empa li boetse li sebelisoa e le mokhoa o mong oa ho sebelisa lipolasetiki tse entsoeng ka peterole ka lijaneng tsa litlolo le lintho tse khōlō tsa ntlo.
