Acide Polylactique (PLA) nigitabo gishya cya bio gishingiye kandi gishobora kwangirika gikozwe mubikoresho fatizo bya krahisi biva mu mutungo w’ibimera ushobora kuvugururwa nkibigori n imyumbati.
Ibikoresho fatizo bya krahisi byera kugirango bibone glucose, hanyuma bigasemburwa hamwe nubwoko bumwe na bumwe kugirango bibyare aside irike cyane. PLA y'ibigori fibre idoda idoda noneho ikomatanya muburyo bwa chimique kugirango ihuze uburemere bwa molekile ya acide polylactique. Ifite ibinyabuzima byiza. Nyuma yo kuyikoresha, mubihe byihariye, irashobora kwangirika rwose na mikorobe miterere yabantu, ikabyara karuboni n'amazi bitanduye ibidukikije. Ibi ni ingirakamaro cyane mu kurengera ibidukikije. PLA idoda idoda ifatwa nkibikoresho byangiza ibidukikije.
Fibre acide polylactique ikozwe mubuhinzi bwubuhinzi bwuzuye ibinyamisogwe nk'ibigori, ingano, na beterave isukari, bisemburwa kugirango bitange aside ya lactique, hanyuma bigabanuke bigashonga no kuzunguruka. Fibre acide polylactique ni fibre synthique ishobora guterwa kandi byoroshye gukura. Imyanda irashobora kwangirika mubisanzwe.
Ibiranga fibre acide polylactique
Imikorere ibora
Polylactique aside fibre yibikoresho ni byinshi kandi birashobora gukoreshwa. Fibre fibre fibre ifite ibinyabuzima byiza kandi irashobora kubora rwose muri dioxyde de carbone na H2O muri kamere nyuma yo kujugunywa. Byombi birashobora kuba ibikoresho fatizo bya acide lactique ikoresheje fotosintezeza. Nyuma yimyaka 2-3 mubutaka, imbaraga za fibre ya PLA zizashira. Niba ishyinguwe hamwe nindi myanda kama, izabora mumezi make. Byongeye kandi, aside polylactique ihindurwamo aside ya lactique na aside cyangwa enzymes mumubiri wumuntu. Acide ya Lactique nigicuruzwa cya metabolike yingirabuzimafatizo kandi irashobora guhindurwa na enzymes kugirango itange karuboni n'amazi. Kubwibyo, fibre acide polylactique nayo ifite biocompatibilité nziza.
Imikorere yo gufata neza
Fibre ya PLA ifite uburyo bwiza bwo kwinjiza no gutwara neza, bisa no kwangirika. Imikorere yo kwinjiza amazi nayo ifitanye isano na morphologie n'imiterere ya fibre. Ubuso burebure bwa fibre ya PLA bufite ibibanza bidasanzwe hamwe nimirongo idahagarara, imyenge cyangwa ibice, bishobora gukora byoroshye ingaruka za capillary kandi bikerekana uburyo bwiza bwo kwinjirira neza, kuvomera no gukwirakwiza amazi.
Ibindi bikorwa
Ifite umuriro muke hamwe no kutagira umuriro; Imikorere yo gusiga irangi kuruta fibre isanzwe yimyenda, ntabwo irwanya aside na alkali, kandi byoroshye hydrolyze. Mugihe cyo gusiga irangi, hakwiye kwitabwaho cyane cyane ingaruka za acide na alkaline; Kwihanganira cyane imirasire ya ultraviolet, ariko bikunda gufotora; Nyuma yamasaha 500 yo hanze, imbaraga za fibre ya PLA zirashobora kugumaho hafi 55% kandi zikagira guhangana nikirere.
Ibikoresho fatizo byo gukora fibre acide polylactique (PLA) ni aside ya lactique, ikozwe mu binyamisogwe, bityo ubu bwoko bwa fibre nabwo bwitwa fibre y'ibigori. Irashobora gukorwa no gusembura beterave cyangwa ibinyampeke hamwe na glucose kugirango igabanye igiciro cyo gutegura polymers acide lactique. Uburemere bukabije bwa molekile ya polylactique irashobora kuboneka hifashishijwe imiti ya polymerisike ya acide lactique cyclic dimers cyangwa polymerisation itaziguye ya acide lactique.
Ibiranga fibre acide polylactique
Ibicuruzwa bikozwe muri acide polylactique bifite biocompatibilité nziza, bioabsorbability, antibacterial na flame retardancy, kandi PLA ifite ubushyuhe bwumuriro muri polymers yangirika.
Fibre acide polylactique irashobora kubora mo dioxyde de carbone n'amazi mubutaka cyangwa mumazi yinyanja. Iyo yatwitse, ntabwo irekura imyuka yubumara kandi ntabwo itera umwanda. Ni fibre yibidukikije irambye. Imyenda yacyo yumva ari nziza, ifite drape nziza, irwanya imirasire ya UV, ifite umuriro mwinshi, kandi ikora neza. Irakwiriye kumyambarire itandukanye, imyidagaduro yo kwidagadura, ibicuruzwa bya siporo, nibicuruzwa by isuku, kandi ifite ibyifuzo byinshi.
Gukoresha fibre acide polylactique
Imiterere yumubiri yaPLA ibigori fibre idoda
Cyane cyane mubijyanye na biomedicine, ifite ibyifuzo byinshi byo gukoresha mubice bine bikurikira.
1. Suturgie yo kubaga
Fibre acide polylactique (PLA) hamwe na cololymer zabo zirashobora gukoreshwa nkibishishwa byo kubaga kugirango bikire ibikomere no kwangirika no kwangirika, kuko bifite biodegradabilite kandi byinjira muri vivo. Ibyateganijwe kubagwa suture bigomba kuba bifite intangiriro yo kurambura
Igipimo cyo gutesha agaciro ubukana nigihe cyo gukira ibikomere.
Mu myaka yashize, ibiganiro byibanze ahanini ku bigize aside irike ya polylactique iremereye, kunoza tekinoroji yo gutunganya suture, no kongera ingufu za mashini ya suture; Igizwe na polymers ifotora PDLA na PLLA irakwiriye cyane kubaga suture yo kubaga, kuko igice cya kirisiti ya PDLA na PLLA gifite imbaraga za mashini, igipimo kinini, kandi kigabanya umuvuduko ugereranije na amorphous PDLA; Igenamigambi ryimikorere myinshi.
2. Ibikoresho byimbere mu gihugu
Imyenda idoda ya PLA irashobora gukoreshwa mugutezimbere aside polylactique, kuzamura cyane imbaraga zambere zibikoresho byagenwe.
3. Tegura ibikoresho byubwubatsi
Fibre ya polylactique irashobora gukoreshwa nkibikoresho byo kuboha cyangwa gutunganya ibikoresho byubwubatsi. Muguhindura microen ibidukikije ya scafold, imikurire yimikorere nimikorere irashobora kugenzurwa, hanyuma gahunda yo guhindurwa, ibice, cyangwa mubikoresho bya vitro birashobora gutangazwa kugirango bigere ku ntego yo gukosora no kubaka imirimo yabuze.
4. Filime yigihe gishya
Periodontal membrane nigikoresho cyo kuyobora no gutunganya ibishya. Ikoresha ururenda nk'inzitizi yo kwirinda no kugenzura imikoranire iri hagati yishinya nigaragara ryumuzi w amenyo, ikarekura umwanya wo gukura kwimitsi ya periosteal na / cyangwa se amagufwa ya alveolar, bityo bikagera ku ngaruka zo gukira indwara zigihe gito. Ukoresheje fibre acide polylactique nkibikoresho fatizo, kuboha impapuro zo kuvugurura igihe kugirango umuntu yinjire.
5. Umuyoboro udasanzwe
6. Ibindi
Bitewe nuburyo bukomeye bwubukanishi hamwe na biodegradabilite, fibre acide polylactique irashobora gukoreshwa nkibipapuro, kaseti ya gaze, n imyenda yakazi ikoreshwa. Imyanda yabo irashobora gutandukana mugihe cyamezi 6 nyuma yo gushyingurwa mubutaka.
