EVOH Gusubiramo Umukino Uhindura mubisubizo byo gupakira

EVOH (inzoga ya Ethylene vinyl) yahindutse ibintu byingirakamaro mu nganda zipakira, cyane cyane kubera inzitizi zayo zisumba izindi. Iyi polymer ya thermoplastique izwi cyane kubera ubushobozi budasanzwe bwo kurwanya imyuka nka ogisijeni, dioxyde de carbone, hamwe n’ibinyabuzima bihindagurika. Mu myaka yashize, isi yose isaba ibicuruzwa bipfunyitse cyane byiyongereye, bitewe n’ibihinduka by’abaguzi ndetse no kubungabunga neza ibiribwa.

Kimwe mu byiza byingenzi bya resin ya EVOH nubushobozi bwayo bwo kubungabunga ubwiza nubwiza bwibicuruzwa. Mu nganda aho ubuzima bwubuzima bwambere, gukoresha EVOH mubipfunyika byibiribwa bituma ababikora bagabanya igipimo cyangirika, bityo kugabanya imyanda. Ibi byarushijeho kuba ingorabahizi mu gihe inganda z’ibiribwa ku isi zihanganye n’ibibazo birambye. Mugihe abaguzi bishimikije ibicuruzwa bishobora kwerekana kugabanuka kwa karuboni, ibigo byinjiza EVOH mubisubizo byabapakira birashoboka ko byunguka kurushanwa.

Abakinnyi bakomeye mubiribwa n'ibinyobwa bashora imari cyane mubuhanga bwa EVOH. Kurugero, ibigo binini nka Amcor na Sealed Air bikomeje guteza imbere ibisubizo bishya byo gupakira birimo ibice bya EVOH. Ibi ntabwo byongera imikorere yibicuruzwa byabo gusa ahubwo bihuza nibikorwa byangiza ibidukikije hifashishijwe ibikoresho bisubirwamo.

Usibye inganda z’ibiribwa, izindi nzego nka farumasi n’amavuta yo kwisiga nazo zungukirwa n’umutungo wa EVOH. Ubushobozi bwo gukumira ubuhehere butuma EVOH ihitamo neza mugupakira imiti yoroheje nibicuruzwa byiza byo kwisiga. Mugihe gahunda yubuzima ishaka kunoza umusaruro w’abarwayi mu gihe ikomeza gukora neza, icyifuzo cyo gupakira neza kandi cyiza kizakomeza kwiyongera.

Nubwo ifite ibyiza byinshi, inganda za EVOH resin zihura nibibazo. Igiciro cy'umusaruro gikomeje kuba inzitizi nyinshi, cyane cyane mugihe ugerageza guhangana nibikoresho gakondo bipakira nka polyethylene na polypropilene. Nyamara, hamwe nubushakashatsi burimo gukorwa niterambere ryikoranabuhanga, ikinyuranyo cyibiciro giteganijwe kugabanuka mumyaka iri imbere, bigatuma EVOH ihitamo neza kubabikora bose.

Mu ncamake, EVOH resin ihindura inganda zipakira hamwe nibintu byihariye bya barrière hamwe nibyangombwa biramba. Ni ngombwa ko abashoramari bakomeza guhuza n'ahantu hagenda hagaragara kugira ngo bakoreshe inyungu z'ikoranabuhanga rya EVOH mu masoko yabo. Mugihe ubukangurambaga bwabaguzi nibisabwa muburyo burambye bugenda bwiyongera, uruhare rwa EVOH murwego rwo gupakira rugiye kurushaho kugaragara.
