Ibigo byagutse umusaruro, ibicuruzwa byarawe icyarimwe nabyo byateje uburyo bwo gutanga ibikoresho fatizo, cyane cyane PBAT, PBS nibindi bikoresho byo gutesha agaciro ibikoresho bya Membranes mumezi 4 gusa, igiciro cyazamutse. Kubwibyo, ibikoresho byangiza hamwe nigiciro gihamye byakururaga.
Poly (aside lactique) (pli), uzwi kandi nka poly (ishata) ibikoresho bya polymer-byinshuti ya polymer yabonetse mumakimbirane yatowe, kandi birashobora guteshwa agaciro ibigori bishingiye kubinyabuzima, kandi birashobora guteshwa agaciro ibigori bishingiye kubinyabuzima, kandi birashobora guterwa burundu ibigori bishingiye ku binyabuzima, kandi birashobora guteshwa agaciro Ibicuruzwa byanyuma, nka CO2 na H2O.
Kubera ibyiza byayo byimbaraga nyinshi zubukanishi, gutunganya byoroshye, ingingo yo gushonga cyane, biodedadablelen hamwe nibidasanzwe, byakoreshejwe cyane mubuhinzi, gupakira ibiryo, ubuvuzi nibindi bibuga. Ibyatsi bitesha agaciro byagaragaye cyane mumyaka yashize.
Mu gusubiza gahunda ya plastike, ibyatsi byimpapuro bikoreshwa cyane mubushinwa. Ariko, ibyatsi byimpapuro biranengwa cyane kubwinyungu zabo mbi. Abakora benshi kandi benshi batangira guhitamo ibikoresho byahinduwe kugirango bakore ibyatsi.
Ariko, nubwo aside ya Polylactike ifite imiterere yubukanishi, kurambura hasi ku kiruhuko (mubisanzwe bitarenze 10%) no gukomera gukema bigabanya ibyo byakoreshwa mubyatsi.
Kubwibyo, hughening yabaye ingingo ishyushye muri iki gihe. Ibikurikira niterambere rya none rya Pla rihurira ubushakashatsi.
Poly - aside lactique (pla) nimwe muri plastiki zikuze zikuze zikuze. Ibikoresho byayo mbisi biva mu fibre y'ibimera bishobora kongerwa, ibigori, ubuhinzi n'ibicuruzwa, n'ibindi, kandi bifite ubuzima bwiza. PLA ifite imitungo ihanitse, isa na polypropiclene plastike, kandi irashobora gusimbuza pp na plastike yamatungo mumirima imwe. Hagati aho, Pla ifite uburebure bwiza, gukorera mu mucyo, intoki, intoki numva ibintu bimwe na bimwe bya antibacterie
Pla
Kugeza ubu, Pla ifite inzira ebyiri zinzira. Umwe afite ubunini bwa Polymeyeli, ni ukuvuga acide ya Lacctique ari umwuma utagira umwuma kandi akandenguriwe munsi yubushyuhe bwinshi nubushyuhe buke. Igikorwa cyo gukora kiroroshye kandi ikiguzi ni gito, ariko uburemere bwa molekile yibicuruzwa ntabwo aringaniye, kandi ingaruka zifatika zirahari.
Undi ni intara ya pactide - gufungura polymerioriation, nuburyo busanzwe bwumusaruro.
Bitesha agaciro Pla
Pla irahagaze neza mubushyuhe bwicyumba, ariko byoroshye gutesha agaciro CO2 namazi mubushyuhe bwo hejuru buke, ibidukikije byibanze acide na microbial. Kubwibyo, ibyatsi birashobora gukoreshwa neza mugihe cyemewe kandi byangiritse ku gihe nyuma yo gutabwa mu kugenzura ibidukikije no gupakira.
Ibintu bigira ingaruka ku guteganya cyane harimo uburemere bwa molekile, Leta ya Crystalline, Ibikorwa by'imishinga, ubushyuhe bw'imbogamiye n'ubushuhe, agaciro ka PH hamwe na microganism y'ibidukikije.
Pla nibindi bikoresho birashobora kugira ingaruka ku gipimo cyateguwe.
Kurugero, pla yongeramo umubare wifu cyangwa ibigori byihuta birashobora kwihutisha cyane igipimo cyo gutesha agaciro.
IMIKORANO
Insulation ivuga ubushobozi bwibikoresho byo gukumira inzira ya gaze cyangwa imyuka y'amazi.
Umutungo wa bariyeri ningirakamaro cyane mugupakira. Kugeza ubu, igikapu gikunze gutesha agaciro ku isoko ni pla / pbat ibikoresho.
Inzitizi yimiterere ya firime yanoze irashobora kwagura umurima usaba.
Ibintu bireba imitungo ya Pla ikubiyemo ibintu byimbere (imiterere ya molecular na leta ya Crystalisation) nibintu byo hanze (ubushyuhe, imbaraga, imbaraga zo hanze).
1. Hejuru yo gushyushya firime izagabanya imitungo yazo, bityo PI ntabwo ikwiriye gupakira ibiryo akeneye gushyushya.
2. Kurambura iki kibazo murwego runaka birashobora kongera imitungo ya bariyeri.
Iyo igipimo cya tensile cyiyongereye kuva kuri 1 kugeza ku 6.5, ko harabatera imbere cyane, bityo imitungo ya bariyeri iratera imbere.
3. Ongeraho inzitizi (nk'ibumba na fibre) kuri pla matrix birashobora kunoza imitungo ya pla.
Ni ukubera ko bariyeri yakomye inzira igoramye yamazi cyangwa uburyo bwa gaze kuri molekile nto.
4. Gutunganya kwivuza hejuru ya firime ya pla birashobora kunoza umutungo wa bariyeri.
