Ethylene-vinyl acetate copolymer CAS 24937-78-8 (EVA) ifite uburyo bwinshi bwo kuyikoresha, ubu bukurikira ni bwo buryo bw'ingenzi ikoreshwamo:
Ikibuga gito cya filime
Filimi y'ubuhinzi: EVA ifite ubushobozi bwo kohereza urumuri neza, irinda ubushyuhe kandi irwanya ikirere, kandi ikunze gukoreshwa mu gukora filimi y'ubuhinzi. Ishobora kubungabunga ubushyuhe n'ubushuhe mu nzu y'ubusitani, igatera imbere mu gukura kw'ibihingwa, kandi yongere igihe cyo gukora filimi.
Filimi yo gupfunyika: Filimi ya EVA ifite ubushobozi bwo koroshya ibintu, ibonerana kandi irinda gutobora, ikwiriye gupfunyika ibintu bitandukanye, nk'ibiribwa, ibyo umuntu akeneye buri munsi, nibindi. Ishobora gutanga imikorere myiza yo kurinda ibintu mu gihe igaragaza imiterere y'ibicuruzwa.
Ikibuga cy'inkweto
Isoli: EVA ifite imiterere yo koroha, irakomera, ifite uburemere bworoshye, idashira, nibindi, niyo mashini nziza yo gukora isoli. Isoli ikozwe muri EVA iraryoshye kwambarwa, ifite ubushobozi bwo gufata impanuka, kandi igabanya umunaniro w'ibirenge.
Hejuru: EVA ishobora kandi gukoreshwa mu gukora ibikoresho byo hejuru, igatanga uburyo bworoshye bwo guhumeka neza, bigatuma inkweto zirushaho kuryoha no kuba nziza.
Agace gashyushye ko gushonga
Kole ishyushye ya EVA: ifite ibyiza byo kuba ifite ubushyuhe bwinshi, irakira vuba, iramira ubushyuhe buke, nibindi, ikoreshwa cyane mu gupfunyika, gufatanya, gukora ibikoresho byo mu nzu n'izindi nganda. Ishobora gukoreshwa mu gufatanya impapuro, imbaho, pulasitiki n'ibindi bikoresho, yoroshye gukoresha, ishobora kunoza imikorere.
Insinga n'umuyoboro w'insinga
Uburyo bwo gukingira: EVA ifite ubushobozi bwo gukingira, irwanya amazi kandi irwanya ingese, ishobora gukoreshwa nk'igikoresho cyo gukingira insinga n'insinga, ishobora kurinda neza insinga n'insinga ingaruka z'ibidukikije byo hanze, kugira ngo ikomeze umutekano n'ubwirinzi bw'ihererekanya ry'amashanyarazi.
Urugo: EVA ishobora kandi gukoreshwa mu gukora urugo rw'insinga n'insinga, itanga uburinzi bwa mekanike n'imikorere yo kurwanya gusaza, yongerera igihe insinga n'insinga zikora.
Izindi nganda
Ibikinisho: EVA ni yoroshye, ntabwo irimo uburozi, nta mpumuro n'ibindi biranga, ikunze gukoreshwa mu gukora ibikinisho, nk'udupira tw'abana, udupira tw'amashusho, n'ibindi, kugira ngo abana bakoreshwe neza kandi neza.
Ibikoresho bya siporo: Bikoreshwa cyane mu bikoresho bya siporo, nka MATS za siporo, MATS za yoga, nibindi, ubworoherane bwabyo n'uburyo bworoshye bishobora gutanga ubufasha bwiza no gutuma umubiri urushaho kumererwa neza.
Ibikoresho by'ifuro: Ifuro rya EVA rifite uburemere bworoshye, ryoroshye, ririnda ubushyuhe, ririnda urusaku n'ibindi bintu, rishobora gukoreshwa mu gukora ubwoko butandukanye bw'ibikoresho by'ifuro.
