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.Umufuka wo gupakira wangiritse bivuga inzira yo kubyara kugirango wongere umubare munini winyongera (nka krahisi, krahisi yahinduwe cyangwa izindi selile, fotosensitizer, agent biodegradative, nibindi), kugirango ihame ryumufuka wapakira plastike, hanyuma ugereranye byoroshye na gutesha agaciro ibidukikije.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 yimifuka ipakira yangiritse igizwe na PLA + PBAT, ishobora kubora burundu mumazi na dioxyde de carbone mumezi 3-6 mugihe ifumbire mvaruganda (dogere 60-70), nta mwanda ku bidukikije.Kuberiki wongeyeho PBAT, uruganda rwumwuga rwo gupakira ibintu byoroshye, mubisobanuro bisobanurwa ni aside ya PBAT adipic aside, 1, 4 - butanediol, acide terephthalic acide copolymer, cyane cyane ni biodegradable synthique alifatique na polimeri ya aromatique, PBAT ifite ibintu byoroshye guhinduka, irashobora gukora amashusho ya firime. , gusohora hanze, gutunganya no gutunganya ibindi.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.
