Ese koko ibikombe bya PLA ntibingiza ibidukikije? Ukuri inyuma y'ibivugwa mu gupakira ifumbire

Uhitamo ibikombe bya PLA kuko bisa n'ibirambye, byumvikana nk'ibifite inshingano, kandi bihuye n'umurava w'ikirango cyawe ku isi. Ariko se byagenda bite niba icyo kimenyetso cy' "icyatsi kibisi" kitavuga ko ari umwimerere w'icyatsi kibisi?

Mu gihe ubucuruzi bwinshi bukoresha ibikoresho bishobora kubora no gushisha mu gushaka ibisubizo birambye byo gupfunyika, benshi barimo kuvumbura ikintu giteye inkeke: ibicuruzwa bisa nkaho bitangiza ibidukikije biri ku isoko akenshi ntibitanga inyungu nyazo ku bidukikije nyuma yo kujugunywa.

Ibikombe bya PLA (polylactic acid) bikunze kuvugwa cyane nk'uburyo bwiza bwo gusimbura plastiki gakondo—ariko ingaruka zabyo nyakuri ku bidukikije ntiziterwa n'icyo bikozwemo, ahubwo ziterwa n'uko biba bimeze nyuma yo kujugunywa.

1. Uburyo ibikombe bya PLA bikorwa n'impamvu bisa n'icyatsi kibisi

PLA, cyangwa aside polylactic, itangira ari bioplastic ikomoka ku isukari y’ibimera ishyushye, akenshi ikomoka ku binyampeke by’ibigori cyangwa ibisheke. Iyi nkomoko ishobora kongera gukoreshwa itangaIbikombe bya PLA"Icyatsi kibisi" cyabo, kuko birinda kwishingikiriza ku biryo bikomoka kuri peteroli bikoreshwa mu bikoresho bisanzwe bya pulasitiki nka PET cyangwa PP.

1.1. Isoko ya PLA ishingiye ku bimera

PLA isobanura aside polylactic, ubwoko bwa pulasitiki ikorwa mu isukari y'ibimera aho kuba amavuta. Ibikoresho fatizo bikunze gukoreshwa cyane ni ibinyampeke by'ibigori biva muri Leta Zunze Ubumwe za Amerika n'ibishanga biva mu bindi bihugu. Abahinzi bahinga ibi bihingwa, bakabisarura, hanyuma bakohereza ibinyampeke cyangwa isukari mu nganda. Aho ngaho, ibi binyampeke bishongeshwa na bagiteri kugira ngo bikore aside lactic. Iyi aside lactic hanyuma ihuzwa n'imiti kugira ngo ikore iminyururu miremire yitwa PLA resin. Kubera ko aho bitangiriye ari ibimera bikura buri mwaka, PLA ifatwa nk'ishobora kongera gukoreshwa aho kwishingikiriza ku bikomoka ku mavuta make. Iyi nkomoko ishobora kongera gukoreshwa ni imwe mu mpamvu nyamukuru amasosiyete yita ibikombe bya PLA bibungabunga ibidukikije.

1.2. Ikoreshwa rito rya lisansi y'ibimera mu musaruro

Gukora ibikombe bya pulasitiki bisanzwe akenshi bitangirana no gucukura peteroli, kuyitunganya, no gukoresha ingufu nyinshi zikomoka kuri peteroli. Ibinyuranye n'ibyo, gukora PLA bikoresha ingufu nke cyane zishingiye kuri peteroli kuko ikintu nyamukuru gikomoka ku bimera. Ubushakashatsi bureba inzira yose yo gukora (bwitwa isuzuma ry'ubuzima) bukunze kugaragaza ko PLA ituma imyuka ihumanya ikirere igabanukaho 50% kugeza kuri 65% mu gihe cyo kuyikora ugereranije na PET plastic. Ibihingwa byahinzwe PLA nabyo bikura dioxyde de carbone mu gihe bikura, ibyo bigafasha kugabanya imwe mu myuka ihumanya ivamo nyuma. Uku guhuza ibiryo bishobora kongera gukoreshwa no kugabanya ikoreshwa ry'ingufu zikomoka ku bimera biha PLA ishusho yayo ikomeye "y'icyatsi" mu bikoresho byo kwamamaza.

2. Isezerano Rikuru: Kwangirika kw'ibinyabuzima no Gushobora Gutunganywa

Kimwe mu bintu bigurishwa cyane ku bikombe bya PLA ni uko bigurishwa nk'ibikombe bishobora gukoreshwa mu ifumbire. Ariko, ubushobozi bwo gukoresha ifumbire bushingiye cyane ku buryo bwo kuyijugunya.

2.1. Icyo gukora ifumbire mvaruganda bisaba mu by'ukuri

PLA yanditseho "ishobora gufumbira," ariko icyo kirango gikoreshwa gusa mu bihe runaka biboneka mu nganda zikora ifumbire mvaruganda. Aha hantu hanini ho gufumbira ifumbire mvaruganda hagumana ubushyuhe buri hagati ya 55°C na 60°C (131–140°F) mu gihe cy'ibyumweru byinshi. Nanone bigumana urwego rukwiye rw'ubushuhe, ogisijeni nyinshi, na za miriyari za mikorobe zikora ifumbire mvaruganda. Ibikoresho bihindurwa buri gihe kugira ngo byose bivangwe neza. Iyo ibi bintu byose bigenzuwe gusa, PLA ishobora gusenyuka neza ikameramo amazi, dioxyde de carbone, n'ibintu bikomoka ku bimera. Ibikoresho byo mu rugo byo gufumbira ifumbire mvaruganda cyangwa ubutaka karemano hafi ya byose ntibitanga ibi bintu nyabyo.

2.2. Igihe PLA Cups zitwara kugira ngo zivunike mu bihe byiza

Iyo bishyizwe mu nganda zicunzwe neza, ibikombe bya PLA bikunze gutangira gushwanyagurika mu byumweru bike. Ibicuruzwa byinshi byemewe bya PLA bigera nibura ku kigero cya 90% mu minsi 90 kugeza ku 120 mu gihe cy'ubushyuhe, ubushuhe, n'imikorere y'udukoko. Nyuma yo kubora burundu, igisigaye ni ifumbire ikungahaye ku ntungamubiri ishobora gukoreshwa mu guhinga ibimera bishya. Ubu buryo bwo gufungana—gutera ifumbire kugeza ku yindi—ni wo mushinga w'ingenzi wa PLA mu kubungabunga ibidukikije. Amabwiriza y'impamyabumenyi nka ASTM D6400 cyangwa EN 13432 apima kandi yemeza iyi mikorere mu nganda zigenzurwa gusa.

3. Ibibazo byo mu Isi Nyayo hamwe no Gukuraho PLA

Nubwo bifite icyemezo cyo gufumbira, ibikombe byinshi bya PLA ntibigera ku nganda zikora ifumbire mvaruganda. Ibi bitanga icyuho kinini hagati y’isezerano ry’ibidukikije n’ukuri kw’ibidukikije.

3.1. Impamvu ibikombe byinshi bya PLA birangira mu myanda

Imijyi mike cyane ifite gahunda zo gukora ifumbire mvaruganda zikira ibintu bya PLA. Nubwo byaba bimeze bityo, ibikombe bigomba gutandukanywa n'imyanda isanzwe bikoherezwa mu kigo gikwiye. Mu by'ukuri, abantu benshi bajugunya ibikombe bya PLA mu bisanduku bisanzwe by'imyanda. Amakamyo atwara imyanda avanga ibintu byose hamwe, kandi imashini zitoragura imyanda mu nganda zisubiramo imyanda cyangwa zikoresha imyanda akenshi ntizishobora gutandukanya PLA n'izindi plastiki. Kubera izi mbogamizi zifatika, inyinshi mu bikombe bya PLA ku isi yose zirangira mu byumba byo kumena imyanda aho kuba mu byumba byo kumena imyanda, uko icyapa cyabyo cyabivuga kose.

3.2. Impamvu PLA idakora mu ifumbire mvaruganda yo mu rugo

Ibirundo by'ifumbire mvaruganda mu rugo akenshi bihora bikonje cyane kurusha iby'inganda, akenshi hagati ya 30°C na 50°C uko bishoboka kose. PLA ikenera ubushyuhe bwinshi buri hejuru ya 55°C kugira ngo yorohe kandi ireke mikorobe ziyitere neza. Iyo idafite ubwo bushyuhe, ibikoresho bicikamo ibice bito buhoro cyane cyangwa ntibigaragare na gato. Abantu benshi bavuga ko basanze uduce twa PLA tukiri kugaragara mu ifumbire mvaruganda mu rugo rwabo nyuma y'umwaka umwe cyangwa ibiri. Mu gikari, PLA ikunda kwitwara nk'ipulasitiki isanzwe kuruta ibisigazwa by'ibiryo cyangwa impapuro.

3.3. Ingaruka z'ibyuka bihumanya ikirere bya Methane mu byobo by'imyanda

Aho imyanda ijugunywa haba hijimye, hafite uburebure buto, kandi hari umwuka wa ogisijeni muke. Muri izi mimerere yo kutagira umwuka uhagije, bimwe mu bintu by’umwimerere birekura umwuka wa methane uko bigenda bishira buhoro buhoro. Nubwo PLA igabanuka buhoro buhoro ugereranyije n’imyanda y’ibiribwa, iracyashobora gukora methane mu gihe cy’imyaka myinshi mu myanda. Methane ni umwuka ukomeye uhumanya ikirere ufata ubushyuhe neza cyane kurusha dioxyde de carbone mu gihe gito. Nubwo ingano iva muri PLA akenshi iba nto ugereranyije n’ibisigazwa by’ibiribwa, buri gace ka methane yongera imihindagurikire y’ikirere iyo ibikombe ibihumbi cyangwa miliyoni byuzuye buri munsi.

4. Ibikombe bya PLA vs Ibikombe bya Plastike gakondo

Kugira ngo hamenyekane niba ibikombe bya PLA ari byiza ku bidukikije, ni ngombwa kubigereranya n'ibindi bikoresho bisanzwe bya pulasitiki mu bipimo bitandukanye by'ibidukikije.

4.1. Inzira ya Karuboni n'Imyuka Ihumanya Ituruka ku Gisozi

Kuva igihe imyaka ihingwa kugeza igihe PLA resin ikorewe, ubusanzwe iyi gahunda itera imyuka mike ihumanya ikirere kuruta gukora PET plastic ikoresheje peteroli. Ubushakashatsi bwinshi buvuga ko imyuka ihumanya ikirere ya PLA iri hasi ho 60-65% ugereranije na PET iyo urebye gusa aho ikorwa. Ariko, niba igikombe cya PLA kitashyizwemo ifumbire ahubwo kikajya mu ifumbire, zimwe muri izo nkunga za mbere zishobora gutakaza uko igihe kigenda gihita bitewe no kurekurwa kwa methane. Iyo ifumbire yuzuye ibaye, ikirere cya karuboni muri rusange kiguma kiri hasi ugereranyije n'ibikombe byinshi bisanzwe bya pulasitiki bikoreshwa rimwe. Inyungu iragaragara cyane iyo ugereranije imiterere y'ifumbire kuva ku ifumbire ugereranyije n'iy'ifumbire kuva ku ifumbire.

4.2. Imbogamizi zo kongera gukoresha ibikoresho n'ingaruka zo kwanduza

Ibikombe bya pulasitiki gakondo bikozwe muri PET cyangwa PP rimwe na rimwe bishobora kongera gukoreshwa iyo byakusanyijwe ukwabyo. Icyakora, PLA isa neza ariko irashonga kandi ikagira imyitwarire itandukanye mu mashini zisubiramo ibikoresho. Iyo ndetse n'ingano nto ya PLA ivanze mu itsinda rya PET risubiramo ibikoresho, ishobora kwangiza umutwaro wose binyuze mu gutuma habaho utudomo duto cyangwa ibara muri pulasitiki nshya. Kubera ko inganda nke cyane zisubiramo ibikoresho zemera PLA, hafi ya byose bikombe bya PLA bifatwa nk'ibidashobora kongera gukoreshwa mu buryo busanzwe. Ibi bituma PLA igorana kuyikoresha mu buryo bugezweho bwo kongera gukoresha ibikoresho kurusha bimwe mu bisigazwa bya pulasitiki.

4.3. Ubucuruzi bushingiye ku bidukikije: Imikoreshereze y'amazi, Imikoreshereze y'ubutaka, n'ubuhinzi

Guhinga ibigori cyangwa ibisheke kuri PLA bisaba ubutaka bwinshi bwo guhinga, amazi yo kuhira, n'ifumbire mvaruganda. Ibi byifuzo by'ubuhinzi bishobora gutera isuri, imiti yica udukoko itemba mu migezi, ndetse no guhangana n'ibihingwa mu turere tumwe na tumwe. Ubushakashatsi bwerekana ko umusaruro wa PLA rimwe na rimwe ukoresha amazi n'ubutaka bwinshi kuruta gukora plastiki zimwe na zimwe. Ifumbire itemba inagira uruhare mu kurabya indabyo z'ibimera n'uduce twapfuye mu biyaga no mu nyanja. Izi ngaruka zitaziguye bivuze ko nubwo PLA igabanya ikoreshwa rya peteroli, ishyira igitutu ku bidukikije ku buhinzi no ku migezi myiza.

Ubusanzwe umusaruro wabyo utuma imyuka ihumanya ikirere igabanuka ugereranije n'ibikombe bya PET iyo bipimwe kuva mu murima ujya mu ruganda. PLA irasobanutse neza, ikomeye ku binyobwa bikonje, kandi yemewe ko ikoreshwa mu kurya. Iyo ibikombe bigeze ku ifumbire y'imborera mu nganda, bihinduka ingirakamaro mu gutunganya ubutaka aho kuguma ari imyanda iteka ryose. Ku bacuruzi n'abaguzi baha agaciro ikoreshwa rito ry'ibikomoka kuri peteroli kandi bakaba bafite uburyo bwo gukora ifumbire ikwiye, PLA itanga inyungu zifatika kuruta plastiki isanzwe.

5.2. Inzitizi n'Ingaruka Zifatika

Ibikombe bya PLA byoroha kandi bigahinduka iyo bihuye n'amazi ashyushye hejuru ya dogere selisiyusi 60, bityo ntibishobora kubika ikawa cyangwa icyayi. Nanone birakomera cyane mu bushyuhe bukonje cyane kurusha bimwe na bimwe bya pulasitiki. Icy'ingenzi kurushaho, kutagira ifumbire mvaruganda ikwirakwira hose bivuze ko inyinshi muri zo zigwa mu myanda aho zimara igihe kirekire kandi zishobora kurekura methane. Guhinga imyaka ya PLA bikoresha amazi menshi, ubutaka, n'ifumbire mvaruganda, bigatera ibindi bihombo ku bidukikije. Izi mbogamizi zifatika kandi zishingiye ku mikorere zibuza PLA kuba igisubizo cyuzuye ku myanda ya pulasitiki ikoreshwa rimwe.
