Intangiriro Muri make Intangiriro ya PLA

Ibyerekeye PLA

PLA, izwi kandi nka polylactide, ni polyester polymerized ikomoka kuri acide lactique.Acide Polylactique ifite biodegradabilite nziza, guhuza no kwinjiza.Nibintu bidafite uburozi, bidashiduka ibikoresho bya polymer.Ibikoresho byayo ni aside ya lactique, ikomoka ahanini kuri fermentation ya krahisi, nk'ibigori n'umuceri.Irashobora kandi kuboneka muri selile, imyanda yo mu gikoni cyangwa imyanda y amafi.

PLA ifite ibikoresho byinshi bibisi, kandi ibicuruzwa biva muri yo birashobora guhimbwa cyangwa gutwikwa, bishobora kuzuza ibisabwa byiterambere rirambye.Gukorera mu mucyo no gukomera, biocompatibilité hamwe nubushyuhe bwa PLA nimpamvu nyamukuru zituma ikoreshwa cyane.

Mubyongeyeho, PLA ifite thermoplastique kandi irashobora gukoreshwa mubice byinshi, nkibikoresho byo gupakira, fibre, nibindi .. Ikoreshwa cyane cyane mubintu bikoreshwa nkibikoresho byo kumeza hamwe nibikoresho byo gupakira, hamwe nibikoresho byamashanyarazi nubuvuzi.
Ugereranije n’ibicuruzwa bikomoka kuri peteroli gakondo, gukoresha ingufu mu gukora aside polylactique ni 20% kugeza kuri 50% by’ibicuruzwa bikomoka kuri peteroli, naho dioxyde de carbone yakozwe ni 50% y’ibicuruzwa bikomoka kuri peteroli.Kubwibyo, iterambere ryibikoresho byangirika bya polylactique birakenewe kugirango ibibazo by’ibidukikije n’ingufu bigabanuke ku isi.

IbirangaPLA
1. Ibinyabuzima
Ugereranije na plastiki gakondo, aside polylactique irashobora kwangirika muri CO2 na H2O na mikorobe n’umucyo.Ibicuruzwa byayo byangirika ntabwo ari uburozi kandi ntacyo bitwaye, kandi ntibizahumanya ibidukikije.Monomer yo gukora aside polylactique ni acide lactique, ishobora guhindurwa nibihingwa nk'ingano, umuceri na beterave isukari cyangwa ibikomoka ku buhinzi.Kubwibyo, ibikoresho fatizo byo kubyara aside polylactique birashobora kongerwa.Acide polylactique nkibintu bigenda byangirika bikoreshwa cyane.
2. Biocompatibilité na Absorbability
Acide polylactique irashobora guhindurwa na aside cyangwa enzyme kugirango ikore aside lactique mumubiri wumuntu.Nka metabolite ya selile, aside ya lactique irashobora kurushaho guhindurwa na enzymes mumubiri, kugirango ikore CO2 na H2O.Kubwibyo, aside polylactique ntabwo ari uburozi kandi ntacyo yangiza kumubiri wumuntu, byongeye kandi ifite biocompatibilité nziza na bioabsorbability.Acide Polylactique yemejwe n’ikigo cy’Amerika gishinzwe ibiryo n’ibiyobyabwenge gishobora gukoreshwa nka biomaterial mu gutera abantu

3. Kumashini
Nkibikoresho bya polimoplastique, aside polylactique ifite plastike nziza nuburyo bwo gutunganya umubiri, hamwe no gushonga cyane hamwe na crysallinity, elastique nziza na flexibilité, hamwe nubushuhe buhebuje.Ibikoresho bya aside polylactique, nkibikoresho bya polymer nka polypropilene (PP), polystirene (PS), na polifhenylene ether resin (PPO), birashobora gutunganywa no gusohora, kurambura, no gutera inshinge.
