Isesengura ku mpinduka mumikoreshereze yimbere ya PE mugihe kizaza.

Kuri ubu, inzira nyamukuru ikoreshwa yapolyethylenemugihugu cyanjye harimo firime, gushushanya inshinge, umuyoboro, umwobo, gushushanya insinga, umugozi, metallocene, gutwikira nubundi bwoko bwingenzi.

Uwa mbere kwihanganira ibintu byinshi, igice kinini cyo gukoresha hasi ni firime. Ku nganda zikora firime, inzira nyamukuru ni firime yubuhinzi, firime yinganda na firime ipakira ibicuruzwa. Nyamara, mu myaka yashize, ibintu nko kubuza imifuka ya pulasitike no kugabanuka gukenewe kwinshi kubera icyorezo byagiye bibabaza inshuro nyinshi, kandi bahura n’ibibazo biteye isoni. Icyifuzo cyibicuruzwa bisanzwe bya firime byajugunywe bizasimburwa buhoro buhoro no kumenyekanisha plastiki yangirika. Abakora amafilime benshi nabo bahura nudushya mu ikoranabuhanga mu nganda, kandi bagenda batera imbere buhoro buhoro bagana amafilime yinganda zisubirwamo kandi zifite ubuziranenge n’imikorere. Ariko, kubera kwangirika kwa firime ya plastike yangiritse, haribisabwa cyane kubipfunyika hanze, cyangwa gukenera firime zipakira hanze zigomba kubikwa igihe kirekire kirenze igihe cyo kwangirika, kandi firime zinganda nizindi nzego ziracyasimburwa, ibicuruzwa bya firime rero bizakomeza gukoreshwa. Yabayeho nkibicuruzwa nyamukuru bimanuka munsi ya polyethylene igihe kirekire, ariko hashobora kubaho umuvuduko mukuzamuka kwikoreshwa no kugabanuka kwikigereranyo.

Byongeye kandi, inganda nko gushushanya inshinge, imiyoboro, n’imyobo bifitanye isano rya bugufi n’umusaruro n’ubuzima bizakomeza kuba ibicuruzwa by’ibanze by’umuguzi munsi ya polyethylene mu myaka mike iri imbere, kandi bizakomeza kwiganjemo ibikorwa remezo, ibikenerwa buri munsi, n’ibikoresho bya gisivili. n'ibikoresho. Imibereho yabantu ifitanye isano nibicuruzwa biramba, kandi ibyifuzo byo kwangirika kwibicuruzwa biragabanuka. Ikibazo nyamukuru cyugarije inganda zavuzwe haruguru muri iki gihe ni uko umuvuduko w’iterambere ry’urwego rutimukanwa wahagaze mu myaka yashize. Bitewe nibintu nkibitekerezo bibi kubitekerezo byabaturage bikoreshwa n’ibyorezo byinshi, iterambere ry’inganda zikora ibicuruzwa rihura n’ikibazo cyo guhangana n’iterambere. Kubwibyo rero, ihinduka ryikigereranyo cyigihe gito ugereranije ni rito, ntiribangamiwe n’ibicuruzwa byangirika, inganda zikoresha imiyoboro zishobora kwibasirwa na politiki, mu gihe imashini zatewe inshinge n’ibicuruzwa bitagira umumaro byibasirwa cyane n’imyumvire y’abaturage, ndetse n’ubwiyongere bw’ubwiyongere. bizatinda mugihe runaka mugihe kizaza gishoboka.

Hamwe niterambere ryiterambere rya siyanse nubuhanga, guhanga abantu no guhanga udushya mubicuruzwa bya pulasitike, hamwe no guhanga ubuziranenge bwibicuruzwa nibisabwa ku bicuruzwa byabigenewe nabyo birahora bitera imbere. Kubwibyo, mugihe kizaza, inganda zikora plastike zizongera ibyifuzo byibikoresho bimwe na bimwe biteza imbere imikorere yibicuruzwa bya pulasitike, nka metallocène, plastike zizunguruka, ibikoresho byo gutwikira hamwe nibindi bicuruzwa byongerewe agaciro cyangwa ibicuruzwa bifite ibisabwa byihariye mubice byihariye . Byongeye kandi, bitewe n’umusaruro wibanze w’inganda zitunganya polyethylene mu myaka yashize, bikaviramo ihinduka rikomeye ry’ibicuruzwa, kandi amakimbirane hagati y’Uburusiya na Ukraine mu mwaka yatumye ibiciro bya peteroli byiyongera ku nyungu ziva muri Ethylene, ndetse n’izamuka ry’ibiciro no gutanga byavuyemo ibicuruzwa bikomeye ubutinganyi. Muri iki gihe, abakora polyethylene baragenda barushaho gukora cyane mu gukora ibicuruzwa byongerewe agaciro nka metallocène, kubumba kuzunguruka, no gutwikira, bijyanye n’iterambere ry’inganda zo hasi. Kubwibyo, umuvuduko wubwiyongere bwibicuruzwa urashobora kwiyongera kurwego runaka mugihe kizaza.

Byongeye kandi, nkuko icyorezo gikomeza inshuro nyinshi, kimwe nubushakashatsi niterambere ryibicuruzwa bishya byakozwe nababikora, fibre polyethylene, ibikoresho byubuvuzi nibirinda ibikoresho byihariye nabyo birakurikiranwa buhoro buhoro kandi bitezwa imbere, kandi ibyifuzo bizaza nabyo biziyongera buhoro buhoro.
