Ni irihe tandukaniro riri hagati yumufuka wibinyabuzima hamwe nisakoshi yuzuye ibinyabuzima

Ibikapu bipfunyika bipfunyika, ibisobanuro birasuzuguritse, ariko imifuka yo gupakira yangiritse igabanijwemo "kwangirika" na "kwangirika rwose" bibiri. Isakoshi yo gupakira yangirika bivuga inzira yumusaruro kugirango wongere umubare munini winyongera (nka krahisi, yahinduwe na krahisi cyangwa indi selile, fotosensitizer, biodegradative agent, nibindi), kugirango ituze ryumufuka wapakira plastike, hanyuma ugereranye byoroshye no kwangirika mubidukikije. Umufuka wuzuye wapakira bivuga igikapu cyo gupakira cya plastiki cyangiritse rwose mumazi na karuboni ya dioxyde. Inkomoko nyamukuru yibi bikoresho byangiritse bitunganyirizwa muri acide lactique, aribyo PLA, biva mu bigori n imyumbati.

Acide Polylactique (PLA) ni ubwoko bushya bwibinyabuzima hamwe nibinyabuzima bishobora kwangirika. Glucose iboneka mubikoresho fatizo bya krahisi hakoreshejwe isakaramentu, hanyuma aside ya lactique ifite isuku nyinshi ihindurwamo glucose hamwe nubwoko bumwe na bumwe, hanyuma aside polylactique ifite uburemere bwa molekile ikomatanyirizwa hamwe na synthesis. Ifite ibinyabuzima byiza, kandi irashobora kwangizwa rwose na mikorobe miterere yabantu mubihe byihariye nyuma yo kuyikoresha, amaherezo ikabyara karuboni n'amazi. Ntabwo yangiza ibidukikije, bifasha cyane kurengera ibidukikije, kandi ni ibikoresho byangiza ibidukikije kubakozi.

Kugeza ubu, ibikoresho nyamukuru bishingiye kuri bio y’imifuka ipakira yangiritse byuzuye bigizwe na PLA + PBAT, ishobora kubora burundu mu mazi na dioxyde de carbone mu mezi 3-6 bitewe n’ifumbire mvaruganda (dogere 60-70), nta kwanduza ibidukikije. Kuberiki wongeyeho PBAT, uruganda rwumwuga rwo gupakira ibintu byoroshye, mubisobanuro bisobanurwa ni aside ya PBAT adipic aside, 1, 4 - butanediol, aside terephthalic acide copolymer, cyane cyane ni biodegradable synthique alifatique na aromatic polymers, PBAT ifite ibintu byoroshye guhinduka, gusohora firime, gusohora no gutunganya. Intego yo kuvanga PLA na PBAT nugutezimbere ubukana, ibinyabuzima no kubumba imiterere ya PLA. PLA na PBAT ntibishobora kubangikana, bityo imikorere ya PLA irashobora kunozwa cyane muguhitamo abahuza bikwiye.
