Ibyiza bya firime yo gupakira

PLA ni kimwe mu bikoresho byakorewe ubushakashatsi kandi byibanze ku binyabuzima byangirika haba mu gihugu ndetse no ku rwego mpuzamahanga, hamwe n’ubuvuzi, gupakira, hamwe na fibre ni byo bice bitatu bizwi cyane. PLA ikorwa cyane cyane muri acide ya lactique naturel, ifite ibinyabuzima byiza kandi biocompatibilité. Ubuzima bwacyo bwubuzima bwibidukikije buri hasi cyane ugereranije nibikoresho bikomoka kuri peteroli, kandi bifatwa nkibikoresho bitanga icyatsi kibisi.

Acide Polylactique (PLA) irashobora kubora rwose muri dioxyde de carbone namazi mubihe bisanzwe nyuma yo kujugunywa. Ifite amazi meza, imiterere yubukanishi, ibinyabuzima, irashobora kwinjizwa n’ibinyabuzima, kandi nta mwanda uhumanya ibidukikije. PLA ifite kandi imashini nziza. Ifite imbaraga zo guhangana cyane, guhindagurika neza hamwe nubushyuhe bwumuriro, plastike, gutunganya, kutagira ibara, kwinjirira neza umwuka wa ogisijeni numwuka wamazi, hamwe no gukorera mu mucyo mwiza, anti mold na antibacterial, hamwe nubuzima bwimyaka 2-3.

Gupakira ibiryo bishingiye kuri firime

Igikorwa cyingenzi cyerekana ibikoresho bipfunyika ni uguhumeka, kandi umurima wo gukoresha ibi bikoresho mubipfunyika urashobora kugenwa ukurikije guhumeka kwayo gutandukanye. Ibikoresho bimwe bipakira bisaba umwuka wa ogisijeni kugirango utange ogisijeni ihagije kubicuruzwa; Ibikoresho bimwe bipakira bisaba imyuka ya ogisijeni mubijyanye nibikoresho, nko kubipakira ibinyobwa, bisaba ibikoresho bishobora kubuza ogisijeni kwinjira mubipfunyika bityo bikabuza gukura. PLA ifite inzitizi ya gaze, inzitizi y'amazi, gukorera mu mucyo, no gucapa neza.

Gukorera mu mucyo

PLA ifite gukorera mu mucyo no kurabagirana, kandi imikorere yayo myiza iragereranywa n'impapuro z'ikirahure na PET, izindi plastiki zangiza ibinyabuzima zidafite. Gukorera mu mucyo no kurabagirana kwa PLA bikubye inshuro 2-3 ibya firime isanzwe ya PP inshuro 10 za LDPE. Gukorera mu mucyo kwinshi bituma gukoresha PLA nkibikoresho byo gupakira bishimishije. Kubipfunyika bombo, kurubu, gupakira bombo byinshi kumasokoFilime yo gupakira.

Kugaragara no gukora ibifirimebirasa na gakondo ya bombo ipakira, hamwe no gukorera mu mucyo mwinshi, kugumana ipfundo ryiza, gucapwa, n'imbaraga. Ifite kandi inzitizi nziza cyane, zishobora kubungabunga neza impumuro ya bombo.

bariyeri

PLA irashobora gukorwa mubicuruzwa bya firime yoroheje bifite umucyo mwinshi, ibyiza bya barrière, gutunganya neza, hamwe nubukanishi, bushobora gukoreshwa mugupakira byoroshye imbuto n'imboga. Irashobora gukora ahantu heza ho guhunika imbuto n'imboga, kugumana imbaraga, gutinda gusaza, no kubungabunga ibara ryabyo, impumuro nziza, uburyohe, nuburyo bugaragara. Ariko iyo bikoreshejwe mubikoresho bipfunyika ibiryo, haracyakenewe guhinduka kugirango uhuze nibiranga ibiryo ubwabyo, kugirango bigerweho neza.

Kurugero, mubikorwa bifatika, ubushakashatsi bwerekanye ko firime zivanze ziruta firime nziza. We Yiyao yapakiye broccoli hamwe na firime nziza ya PLA na firime ya PLA, ayibika kuri (22 ± 3) ℃. Yahoraga agerageza impinduka mubipimo bitandukanye bya physiologique na biohimiki ya broccoli mugihe cyo kubika. Ibisubizo byerekanye ko firime ya PLA ifite ingaruka nziza zo kubungabunga broccoli yabitswe mubushyuhe bwicyumba. Irashobora gukora urwego rwubushuhe hamwe nikirere kigenzurwa imbere mumifuka ipakira ifasha muguhindura imyuka ya broccoli hamwe na metabolisme, kugumana ubwiza bwa broccoli no kubungabunga uburyohe bwayo nuburyohe bwayo, bityo bikongerera ubuzima bwa broccoli mubushyuhe bwicyumba 23 iminsi.

Igikorwa cya antibacterial

PLA irashobora gukora ibidukikije bidafite aside irike hejuru yibicuruzwa, bitanga ishingiro ryimiterere ya antibacterial na anti mold. Niba izindi miti igabanya ubukana ikoreshwa hamwe, igipimo cya antibacterial gishobora kugera hejuru ya 90%, bigatuma gikwirakwizwa na antibacterial gupakira ibicuruzwa. Yin Min yize ku ngaruka zo kubungabunga ubwoko bushya bwa firime ya PLA nano antibacterial composite ya firime ku bihumyo biribwa ukoresheje Agaricus bisporus na Auricularia auricula nkurugero, kugirango wongere ubuzima bwibihumyo biribwa kandi ukomeze ubuzima bwiza. Ibisubizo byagaragaje ko amavuta ya ngombwa ya PLA / rosemary (REO) / AgO ya compte ishobora gutinza neza igabanuka rya vitamine C muri auricularia auricula.

Ugereranije na firime ya LDPE, firime ya PLA, na firime ya PLA / GEO / TiO2, amazi ya firime ya PLA / GEO / Ag yibumbiye hejuru cyane ugereranije nizindi firime. Duhereye kuri ibi, dushobora kwanzura ko ishobora gukumira neza ishyirwaho ryamazi yegeranye kandi ikagera ku ngaruka zo kubuza mikorobe; Muri icyo gihe, ifite kandi ingaruka nziza za antibacterial, zishobora kubuza neza iyororoka rya mikorobe mugihe cyo kubika ugutwi kwa zahabu, kandi irashobora kongera igihe cyo kubaho kugeza ku minsi 16.

Ugereranije na firime isanzwe ya PE cling, PLA ifite ingaruka nziza

Gereranya ingaruka zo kubungabungaPE firimegupfunyika na firime ya PLA kuri broccoli. Ibisubizo byagaragaje ko gukoresha paki ya firime ya PLA bishobora kubuza umuhondo no kumurika amata ya broccoli, bikabungabunga neza ibirimo chlorophyll, vitamine C, hamwe n’ibishishwa bya elegitoronike muri broccoli. Filime ya PLA ifite uburyo bwiza bwo guhitamo gazi, ifasha kurema ububiko buke bwa O2 hamwe na CO2 murwego rwo kubika imbere mumifuka ipakira PLA, bityo bikabuza ibikorwa byubuzima bwa broccoli, kugabanya gutakaza amazi no gukoresha intungamubiri. Ibisubizo byerekanye ko ugereranije na PE bipfunyika bipfunyika, gupakira firime ya PLA birashobora kongera igihe cyubuzima bwa broccoli mubushyuhe bwicyumba iminsi 1-2, kandi ingaruka zo kubungabunga ni ngombwa.
