Amakuru - Ubuyobozi bwa PLA - Acide Polylactique

Guhindura ibicuruzwa

PLA ni iki? Ikintu cyose Ukeneye Kumenya

Wigeze ushakisha ubundi buryo bwa peteroli bushingiye kuri peteroli no gupakira? Isoko ryiki gihe riragenda ryerekeza kubicuruzwa byangiza kandi byangiza ibidukikije bikozwe mubishobora kuvugururwa.

Filime ya PLAibicuruzwa byahise bihinduka kimwe mubinyabuzima bizwi cyane kandi byangiza ibidukikije ku isoko. Ubushakashatsi bwakozwe mu 2017 bwerekanye ko gusimbuza plastiki zishingiye kuri peteroli na plastiki zishingiye kuri bio bishobora kugabanya ibyuka bihumanya ikirere mu nganda ku gipimo cya 25%.

PLA ni iki?

PLA, cyangwa aside polylactique, ikorwa mubisukari byose bisembuye. PLA nyinshi ikozwe mubigori kuko ibigori nimwe mubisukari bihendutse kandi biboneka kwisi yose. Nyamara, ibisheke, umuzi wa tapioca, imyumbati, hamwe na beterave isukari nubundi buryo.

Kimwe nibintu byinshi bijyanye na chimie, inzira yo gukora PLA iva mu bigori iragoye. Ariko, birashobora gusobanurwa muburyo buke butaziguye.

Nigute ibicuruzwa bya PLA bikorwa?

Intambwe zifatizo zo gukora aside polylactique iva mu bigori ni izi zikurikira:

1. Ibigori bya mbere byibigori bigomba guhinduka mubisukari binyuze muburyo bwa mashini bita gusya. Gusya bitose bitandukanya ibinyamisogwe nintete. Acide cyangwa enzymes byongeweho iyo ibice bitandukanijwe. Noneho, barashyushye kugirango bahindure ibinyamisogwe muri dextrose (bita isukari).

2. Ibikurikira, dextrose irasembuwe. Bumwe mu buryo busanzwe bwa fermentation burimo kongeramo bacteri za Lactobacillus kuri dextrose. Ibi na byo, bitera aside ya lactique.

3. Acide ya lactique noneho ihinduka lactide, dimer-impeta ya acide lactique. Iyi molekile ya lactide ihuza hamwe kugirango ikore polymers.

4. Ibisubizo bya polymerisiyasi ni uduce duto twa plastike ya polylactique ya plastike ishobora guhindurwamo ibintu byinshi bya plastiki ya PLA.

Ni izihe nyungu zibicuruzwa bya PLA?

PLA isaba ingufu nkeya 65% kubyara umusaruro kuruta plastiki gakondo, ishingiye kuri peteroli. Isohora kandi imyuka ya parike ya 68%. Kandi ibyo ntabwo aribyo byose:

Inyungu ku bidukikije:

Ugereranije na PET plastike - Ibice birenga 95% bya plastiki kwisi byakozwe muri gaze gasanzwe cyangwa peteroli. Amashanyarazi ashingiye kuri lisansi ntabwo yangiza gusa; nabo ni ibikoresho bitagira ingano. Ibicuruzwa bya PLA byerekana imikorere, ishobora kuvugururwa, kandi igereranywa no gusimburwa.

Bio-ishingiye- Ibikoresho bishingiye kuri bio biva mubuhinzi cyangwa ibimera bishobora kuvugururwa. Kuberako ibicuruzwa byose bya PLA biva mubisukari, aside polylactique ifatwa nkibinyabuzima.

Biodegradable- Ibicuruzwa bya PLA bigera ku rwego mpuzamahanga rwo kwangiza ibinyabuzima, mu buryo busanzwe butesha agaciro aho kurunda imyanda. Birasaba ibintu bimwe na bimwe gutesha agaciro vuba. Mu nganda ifumbire mvaruganda, irashobora gusenyuka muminsi 45-90.

Ntabwo isohora imyotsi yubumara - Bitandukanye nibindi bya plastiki, bioplastique ntabwo isohora imyotsi yubumara iyo yatwitse.

Thermoplastique- PLA ni thermoplastique, kuburyo ishobora guhinduka kandi ikagenda neza iyo ishyutswe nubushyuhe bwayo. Irashobora gukomera no guterwa inshinge muburyo butandukanye bigatuma iba amahitamo akomeye yo gupakira ibiryo no gucapa 3D.

Ibiryo Kwemeza-byemewe- Acide Polylactique yemerwa nkibisanzwe bizwi nka polymer Yizewe (GRAS) kandi ifite umutekano mukubona ibiryo.

Ibyiza byo gupakira ibiryo:

Ntabwo bafite imiti yangiza nkibicuruzwa bikomoka kuri peteroli

Nkomeye nka plastiki zisanzwe

Gukonjesha

Igikombe gishobora gutwara ubushyuhe bugera kuri 110 ° F (ibikoresho bya PLA birashobora gutwara ubushyuhe bugera kuri 200 ° F)

Ntabwo ari uburozi, karubone idafite aho ibogamiye, na 100% ishobora kuvugururwa

Mubihe byashize, mugihe abakora ibiryo bya serivise bifuzaga guhinduranya ibicuruzwa bitangiza ibidukikije, bashobora kuba barabonye ibicuruzwa bihenze kandi byoroheje. Ariko PLA irakora, igiciro cyiza, kandi kirambye. Guhindura ibyo bicuruzwa nintambwe yingenzi yo kugabanya ubucuruzi bwibiribwa bya karuboni.

Usibye gupakira ibiryo, ni ubuhe bundi buryo bukoreshwa muri PLA?

Iyo yakozwe bwa mbere, PLA yaguze amadorari 200 yo gukora ikiro kimwe. Bitewe nudushya mubikorwa byo gukora, bisaba munsi y $ 1 kuri pound kugirango ikore uyumunsi. Kuberako bitakibuza ikiguzi, aside polylactique ifite ubushobozi bwo kwakirwa cyane.

Ibikoreshwa cyane harimo:

3D icapiro ryibikoresho

Gupakira ibiryo

Gupakira imyenda

Gupakira

Muri izi porogaramu zose, ubundi buryo bwa PLA bwerekana ibyiza bigaragara kubikoresho gakondo.

Kurugero, muri printer ya 3D, filime ya PLA nimwe mumahitamo azwi cyane. Bafite aho bashonga munsi yandi mahitamo ya filime, kuborohereza no gukoresha neza. Icapiro rya 3D PLA filament isohora lactide, ifatwa nkumwotsi udafite uburozi. Rero, bitandukanye nubundi buryo bwa filament, iracapura nta gusohora uburozi bwangiza.

Irerekana kandi ibyiza bimwe bigaragara mubuvuzi. Iratoneshwa kubera biocompatibilité no kwangirika kwumutekano mugihe ibicuruzwa bya PLA bigenda byangirika muri acide lactique. Imibiri yacu isanzwe itanga aside ya lactique, kubwibyo rero ni ibintu bifatika. Kubera iyo mpamvu, PLA ikoreshwa kenshi muri sisitemu yo gutanga ibiyobyabwenge, gutera imiti, no gukora inganda.

Mwisi ya fibre hamwe nimyenda, abunganira bagamije gusimbuza polyester idasubirwaho na fibre ya PLA. Imyenda n'imyenda bikozwe muri fibre ya PLA biroroshye, bihumeka, kandi birashobora gukoreshwa.

PLA ikoreshwa cyane mubikorwa byo gupakira. Ibigo bikomeye nka Walmart, Newman's Own Organics na Wild Oats byose byatangiye gukoresha ifumbire mvaruganda kubera ibidukikije.

Ibicuruzwa byo gupakira PLA birakwiye kubucuruzi bwanjye?

Niba ubucuruzi bwawe bukoresha kimwe mubintu bikurikira kandi ukaba ushishikajwe no kuramba no kugabanya ibikorwa bya karuboni yubucuruzi bwawe, noneho gupakira PLA nuburyo bwiza cyane:

Ibikombe (ibikombe bikonje)

Gutanga ibikoresho

Gupakira

Abangiza ibiryo

Ibyatsi

Ikawa

Kugira ngo umenye byinshi kubyerekeranye na YITO Packaging ihendutse kandi yangiza ibidukikije bya PLA, vugana!
