EVA ni kane mu bunini bwa Ethylene ikurikirana nyuma ya HDPE, LDPE na LLDPE.Ugereranije nibikoresho gakondo, igiciro cyacyo kiri hasi cyane.Abantu benshi batekereza ko ibikoresho bya EVA bifuro aribwo buryo bwiza bwo guhuza ibishishwa byoroshye nigikonoshwa cyoroshye, bikagumana ibyiza byifuro yoroshye kandi ikomeye mugihe ureka ibibi.Na none kandi, ihinduka ryihariye muburyo bwo gushushanya ibikoresho no mubushobozi bwo gukora nabyo ni ikintu gikomeye muri bimwe mubigo bikomeye ku isi ndetse nibirango bihinduka ifuro rya EVA mugihe bikenewe ibikoresho byo mu rwego rwo hejuru, bihendutse.
Kurenza guhinduka, ibikoresho bya EVA bifata ubuzima bwacu bwa buri munsi nibikorwa byubucuruzi, kandi byabyaye abakoresha amaherezo.Inkweto, imiti, imbaho zifotora, siporo n imyidagaduro, ibikinisho, amagorofa / yoga, ibikoresho byo kwa muganga, ibikoresho byo gukingira, wat
Ibicuruzwa bya siporo birakenewe cyane kubicuruzwa bya pulasitiki biramba, kandi igice cyisoko ryibikoresho bya EVA gikomeje gutangiza iterambere rishya.
丨 Imiterere yumubiri nubukanishi
Imiterere ya EVA copolymers igenwa cyane cyane nibirimo vinyl acetate hamwe nurwego rwamazi.Ubwiyongere bwibirimo VA bwongera ubucucike, gukorera mu mucyo no guhuza ibikoresho mugihe bigabanya gushonga no gukomera.Ethylene-vinyl acetate copolymer (EVA) ni ibintu byoroshye cyane bishobora gucumurwa kugirango bibe ifuro isa na reberi, ariko ifite imbaraga zidasanzwe.Irashobora guhinduka inshuro eshatu kurenza ubukana buke bwa polyethylene (LDPE), ifite uburebure bwa 750%, kandi ifite ubushyuhe ntarengwa bwa 96 ° C.
Ukurikije ibiyigize mubikorwa byo kubyara, impamyabumenyi zitandukanye za EVA zikomeye zirashobora kugerwaho.Ni ngombwa gukomeza urwego ruciriritse rwo gukomera kuko EVA itagarura imiterere yayo nyuma yo kwikuramo bikomeje.Ugereranije na EVA ikomeye, EVA yoroshye ntishobora kurwanya abrasion kandi ifite igihe gito cyo kubaho muri sole, ariko iroroshye.
丨 Ibikoresho bya EVA
Gushonga kwa EVA bigabanuka hamwe no kwiyongera kwa VA.Kubwibyo, gukoresha ubushyuhe bwa copolymer buri hasi ugereranije na homopolymer ihuye (LDPE).Ubushyuhe ntarengwa bwo gukora bwakazi buri munsi yubushyuhe bwo koroshya Vicat.Kimwe na polimeri zose za termoplastique, ubushyuhe buterwa nigihe cyurwego nurwego rwimikorere ya mashini aho akazi gakorerwa ubushyuhe.Ubushyuhe bugenda bwiyongera, ubushyuhe bwo kugabanuka buragabanuka kugeza igeze mu kibaya cyegereye gushonga.
