Ethylene-vinyl acetate copolymer CAS 24937-78-8 (EVA) ifite uburyo bwinshi bwo gusaba, ibikurikira nibice byingenzi bikoreshwa:
Umwanya muto wa firime
Filime yubuhinzi: EVA ifite itumanaho ryiza, kubungabunga ubushyuhe no kurwanya ikirere, kandi ikoreshwa kenshi mugukora firime yubuhinzi. Irashobora kubungabunga neza ubushyuhe nubushuhe muri pariki, bigatera imbere gukura kw ibihingwa, no kongera ubuzima bwa firime.
Filime yo gupakira: Filime ya EVA ifite imiterere ihindagurika, gukorera mu mucyo no kurwanya puncture, ibereye gupakira ibicuruzwa bitandukanye, nkibiryo, ibikenerwa bya buri munsi, nibindi. Irashobora gutanga imikorere myiza yo kurinda mugihe yerekana ibicuruzwa.
Umwanya wibikoresho byinkweto
Sole: EVA ifite ibiranga ubworoherane, elastique nziza, uburemere bworoshye, kwambara birwanya, nibindi, nibikoresho byiza byo gukora wenyine. Ikibaho gikozwe muri EVA cyoroshye kwambara, gifite imikorere myiza yo gukuramo, kandi gishobora kugabanya umunaniro wamaguru.
Hejuru: EVA irashobora kandi gukoreshwa mugukora ibikoresho byo hejuru, gutanga gukorakora byoroshye no guhumeka neza, bigatuma inkweto zoroha kandi nziza.
Umuriro ushushe wumurima
EVA ishyushye ifata neza: ifite ibyiza byo kwiyegeranya gukomeye, gukira vuba, kurwanya ubushyuhe buke, nibindi, bikoreshwa cyane mubipakira, guhambira, gukora ibikoresho byo mu nzu nizindi nganda. Irashobora gukoreshwa muguhuza impapuro, ibiti, plastike nibindi bikoresho, byoroshye gukora, birashobora kunoza umusaruro.
Umuyoboro winsinga
Igikoresho cyo gukumira: EVA ifite imikorere myiza yo gukumira, kurwanya amazi no kurwanya ruswa yangiza, irashobora gukoreshwa nkibikoresho byifashisha insinga n’insinga, birashobora kurinda neza insinga n’umugozi ingaruka z’ibidukikije, kugira ngo umutekano wizewe kandi wizewe.
Icyatsi: EVA irashobora kandi gukoreshwa mugukora icyuma cyinsinga ninsinga, gutanga uburinzi bwimashini no kurwanya gusaza, byongerera igihe cyumurimo winsinga na kabili.
Indi mirima
Ibikinisho: EVA iroroshye, idafite uburozi, impumuro nziza nibindi biranga, akenshi ikoreshwa mugukora ibikinisho, nkimipira y ibikinisho byabana, ibisubizo, nibindi, kugirango umutekano hamwe nibyiza byo gukoresha abana.
Ibicuruzwa bya siporo: Irakoreshwa kandi cyane mubicuruzwa bya siporo, nka siporo MATS, yoga MATS, nibindi, ubworoherane nubworoherane bishobora gutanga inkunga nziza ningaruka zo kwisunika.
Ibicuruzwa byinshi: EVA ifuro ifite uburemere bworoshye, yoroshye, kubika ubushyuhe, kubika amajwi nibindi bintu, irashobora gukoreshwa mugukora ibicuruzwa bitandukanye.
