PE ni iki? Ni ibihe bintu uzi ku mpapuro zitwikiriwe na PE?

Buri wese agomba kumenya impapuro. Kuko dushobora kubona ubwoko bwose bw’impapuro mu bice byinshi mu buzima bwa buri munsi. Urugero, tuzi neza ibikombe by’impapuro, amasahani y’impapuro, amasahani y’impapuro n’udusanduku tw’ibiribwa byihuse. Twese tuzi ko impapuro ari hygroscopic (zifata ubushuhe byoroshye) kandi zifite imbaraga nke zo guturika. Ariko niba witonze, uzasanga izi mpapuro zifite agapira k’imbere gasobanutse, keza kandi koroshye. Iyo ni filime ya PE, isa nkaho ishyira ikoti ry’ubumaji ku mpapuro, ikayiha imbaraga zidasanzwe zo kudatinya amazi n’amavuta. Reka duhurize hamwe ibanga ry’impapuro zipfutse!

PE ni iki?

Mbere yo gusobanukirwa impapuro zitwikiriwe na PE, reka tuvuge ku bikoresho byazo by’ingenzi – polyethylene. Polyethylene ni ijambo rihinnye rya PE, ari ryo resine ya thermoplastic yakuwe muri ethylene. Isura ya polyethylene ni uduce tw’umweru dusa n’amata, tudafite uburyohe, impumuro, ntabwo ari uburozi kandi twumva nk’ifiriti. Ikiranga polyethylene ni gito, gifite ubushobozi bwo kurwanya ubukonje, kudahungabana kw’imiti, gukingira amashanyarazi n’ibindi bintu. Bityo ifite uburyo bwinshi bwo kuyikoresha. Ikoreshwa cyane cyane mu gukora filime, ibikoresho byo gupfunyika, ibikoresho byo mu gikoni, imiyoboro, insinga n’insinga, ibintu bikenewe buri munsi, nibindi. Ikindi kandi, ishobora gukoreshwa nk’ibikoresho byo gukingira amashanyarazi byihuta cyane kuri televiziyo, radar, nibindi. Kuva yakoreshwa mu 1922, polyethylene yahindutse resine nini cyane ku isi kandi ikoreshwa cyane mu gupfunyika. Ifite umwanya w’ingenzi mu nganda za plastiki.

Gushyira mu byiciro PE
Bitewe n’uburyo butandukanye bwo gukora polimeneri, imiterere yayo nayo iratandukanye, kandi imiterere y’ibicuruzwa nayo iratandukanye cyane. Ahanini ishobora kugabanywamo: Polyethylene yo mu bwoko bwa Low-Density (LDPE), Polyethylene yo mu bwoko bwa Linear Low-Density (LLDPE), Polyethylene yo mu bwoko bwa High-Density (HDPE).
LDPE: Ikoreshwa cyane cyane mu mpapuro z’ubukorikori, filime y’ubuhinzi, filime yo gupfunyika mu nganda, insinga, nibindi;
LLDPE: Ikoreshwa cyane cyane ku nsinga n’insinga, imiyoboro, ibintu bikenerwa buri munsi, nibindi;
HDPE: Ikoreshwa cyane cyane mu gukora imigozi, imigozi, inshundura zo kuroba, nibindi.

 

Ikwirakwizwa ry’ubushobozi bwo gukora PE hakurikijwe igihugu
Kugeza muri Mata 2022, ubushobozi bwo gukora PE mu Bushinwa bwageze kuri toni miliyoni 29.18, bingana na 21% by’ubushobozi bwose bwo gukora PE ku isi. Amakuru agaragaza ko ubushobozi bwo gukora PE ku isi bwiganje cyane mu Bushinwa, Leta Zunze Ubumwe za Amerika na Arabiya Sawudite. Ubushinwa ni cyo gihugu gifite ubushobozi bwinshi bwo gukora politene ku isi.

 

 

Impapuro zitwikiriwe na PE ni iki?

Twamaze gusobanukirwa neza ibya PE haruguru, none se impapuro zitwikiriwe na PE ni iki? Muri make, impapuro zitwikiriwe na PE ni ibikoresho bigizwe n’impapuro nk’ibikoresho by’ibanze kandi bitwikiriwe n’urupapuro rwa polyethylene ku mpapuro z’ibanze, ni ukuvuga ko uduce twa pulasitiki dutwikiriwe ku buso bw’impapuro n’imashini ikoresha icyuma. Impapuro zoroshye kunyagirwa, ariko nyuma yo guhuzwa neza na polyethylene, impapuro zitwikiriwe zishobora kugira ingaruka zo kudapfa amazi, kudakoresha amavuta no kudashyuha cyane.

Gushyira mu byiciro impapuro zitwikiriwe na PE

Dukurikije itandukaniro riri hagati y’umubare w’ifishi itwikiriwe, ishobora kugabanywamo impapuro zitwikiriwe na PE zifite impande imwe, impapuro zitwikiriwe na PE zifite impande ebyiri, n’impapuro zitwikiriwe na PE zifite ibara ry’urukiramende.

1. Impapuro zitwikiriwe na PE zifite uruhande rumwe
Impapuro zometseho PE zifite uruhande rumwe zitwikiriwe na PE film ku ruhande rumwe rw’impapuro zo hasi. Zikoreshwa mu bikombe bishyushye byo kunyweramo, impapuro za hamburger, n’ibindi.
2. Impapuro zometseho PE zifite impande ebyiri
Impapuro zitwikiriwe na PE zifite impande ebyiri ni PE ku mpande zombi z’impapuro zo hasi. Zikoreshwa mu bikombe bikonje byo kunywa.
Impapuro zipfutse hagati y’urupapuro

Impapuro zitwikiriwe na Sandwich zigomba gushyira PE coating hagati y’impapuro ebyiri z’ibanze kugira ngo impapuro imwe zihuzwe kugira ngo zongere ubwiza bw’impapuro.
Ikunze gukoreshwa mu: gupfunyikamo desiccant, mu mifuka yo gupfunyikamo ibiryo, nibindi.
Dukurikije uburyo butandukanye bwo gusiga, ishobora kugabanywamo ubwoko bubiri: filime y’urumuri n’iy’urumuri.
Filimi y’umukara ni firime ya polyethylene ibonerana ifite impande ebyiri ifite ubuso burabagirana n’intoki zoroshye. Filimi y’umukara ni firime ya polyethylene itagira umukara ifite firime y’umukara ifite ubuso bufunze.
Amabara y’urukiramende afite ubusobanuro bwo hejuru kandi ibyacapwe bifite amabara menshi. Filimi zitameze neza ziba zifite amabara adasobanutse.
Ikoreshwa ry’impapuro zipfutse
Impapuro zipfutse zifitanye isano rya hafi n’ubuzima bwacu bwa buri munsi kandi zifite uburyo bwinshi bwo kuzikoresha, cyane cyane mu gupfunyika, mu biribwa, mu buvuzi, mu by’ikoranabuhanga, mu bikoresho, mu gukata uduce, n’ibindi.

Uburyo bwo gukoresha impapuro zipfutse:

Uburyo bwo gukoresha impapuro zipfutse
1. Imiti: gupfunyikamo umuti wo koza uruhu, utubumbe tw’inyenzi, ifu yo kumesa, imiti irinda ubushyuhe.
2. Ibiryo: imifuka y’amakaroni, ipaki ya ayisikrimu, amata.
