Filimi ya EVA ni ubwoko bw'ibikoresho bya firimi ifite ubukana bwinshi ikozwe muri resin ya polymer (ethylene-vinyl acetate copolymer) nk'ibikoresho by'ibanze, yongeramo inyongera zidasanzwe no gutunganya hakoreshejwe ibikoresho byihariye. Hamwe n'ubushakashatsi bukomeje no guteza imbere firimi ya EVA, firimi ya EVA ikomeje gukura, kandi firimi ya EVA yo mu gihugu yabaye iyoherezwa mu mahanga iturutse mu mahanga.
Abantu benshi batekereza ko firime ya EVA ishobora gukoreshwa gusa mu gushariza imbere, ariko kuva mu 2007, Shandong Fangding Safety Glass Technology Co., Ltd (yabanjirije Fangding Technology Co., Ltd.) yasabye icyemezo cya CCC, kigaragaza ko firime ya EVA yujuje ibisabwa ku rwego rw'igihugu ku birahuri byo hanze mu bijyanye n'ubukomezi, ubwisanzure cyangwa gufatana. Kuva icyo gihe, byakuyeho impaka z'uko PVB ari yo yonyine ikoreshwa mu ikoranabuhanga ryo hanze mu Bushinwa.
Filimi ya EVA mu bikorwa by'ubuhanga bwo hanze:
★ Muri Werurwe 2009, igihugu cyatangiye gushyiraho, muri Werurwe 2010, itangazo ryemewe ry’amahame ngenderwaho y’igihugu agenga ibirahure bya laminated rivuga ko filimi ya PVB igomba gukoreshwa ku birahure by’imodoka. Kandi ikirahure cya laminated cyo mu nyubako, nk’urukuta rw’ibaraza, igisenge cy’amatara, amadirishya y’ubucuruzi, urukuta rw’amadirishya y’ibirahure, filimi ya PVB na EVA birashobora gukoreshwa.
Ubudahangarwa bw'urumuri rwa EVA, kudatinya amazi, kudahangana n'ikirere, kudahangana n'ubushyuhe, ingaruka zo kurwanya urusaku ni byiza kurusha PVB, hamwe no kubika ibintu byoroshye, ikoranabuhanga ryoroshye ryo gutunganya, gukora neza, no ku giciro gito, amasosiyete menshi akunda gukoresha EVA cyane.
Buri wese mu nganda azi ko iyo autoclave ikoze mu kirahure cya laminated, ari ngombwa gukoresha imifuka ya silicone mu gusukura mbere yo kuyivanamo, ndetse n'amasosiyete amwe kugira ngo azigame amafaranga, kuyisukura mbere yo kuyivanamo imifuka ya pulasitiki ikoreshwa mu gihe runaka, hanyuma ikajya muri autoclave, ibyo bikaba bigoye cyane kandi igiciro kikaba kiri hejuru.
Ariko itanura rya EVA rikemura iki kibazo: ikirahure cya laminated gishobora gushyirwa mu itanura kugira ngo gitere umuvuduko mbere, hanyuma kikajya muri autoclave. Ubu, hamwe n'iterambere ry'ikoranabuhanga, Fangding Technology Co., Ltd. yateguye ibikoresho by'ikirahure bya laminated bishobora gucurwa rimwe, ibyo bikaba bizigama cyane igihe n'ikiguzi.
Gukoresha firime ya EVA ku kirahuri cy'imitako:
Ibirahure by'ubugeni nk'insinga, imyenda, impapuro z'amafoto, n'inkunga imwe bigomba gukorwa hakoreshejwe firime ya EVA, cyane cyane ikirahure gishya cy'ubugeni gifite ibintu nyabyo hagati, nk'indabyo nyazo n'ibyatsi by'urubingo. Ubu ubwoko bw'ibirahure by'ubugeni byoherezwa mu mahanga ahanini.
Gukoresha filime ya EVA ku kirahuri gishya cy'ingufu:
Ikoreshwa rya filime ya EVA mu ngufu nshya rigaragarira cyane cyane mu mapine y'izuba ya photovoltaic, ikirahure gitwara umuriro, ikirahure kidasohora umuriro n'ibindi. Ikorwa rya filime za photovoltaic zitwara umuriro zikorwa muri silicon wafer na circuit board hamwe na filime ya EVA ivanze, ubusanzwe ikorwa mu mashini itwara umuriro; ikirahure gisanzwe gitwara umuriro gishobora gukorwa gikoresha filime itwara umuriro (ITO film) hejuru y'ikirahure gisanzwe. Ubu ikirahure gitwara umuriro ni ikirahure gikozwe muri filime ya EVA na filime itwara umuriro, kandi bimwe muri ibyo birahure nabyo bishyizwemo LED, ikaba ari nziza kandi ishimishije.
Ikirahure gihinduranya ni ubwoko bushya bw'ibirahure byihariye bikoresha amashanyarazi bihuza firime y'amazi na firime ya EVA hagati y'ibirahure bibiri, hanyuma bigashyiraho imiterere y'ikirahure nyuma y'ubushyuhe n'umuvuduko runaka. Ubu ikirahure gishya cy'ingufu gikozwe muri firime ya EVA cyakoreshejwe cyane haba mu bucuruzi, ahantu hahurira abantu benshi ndetse no mu ngo z'imiryango.
Uruhare rwa filime ya EVA mu ikirahuri cy'inganda:
Ikirahure cyo ku muryango wa firigo n'imashini imesa ubu ni ibirahure byoroshye kandi ibikoresho byihariye bifite uburebure bwa mm 3.2 hamwe na filimi ya EVA bishyirwa hamwe ku bushyuhe bwinshi, bikaba ari byiza kandi bitekanye.
Kugira ngo habeho ibyifuzo by'abakiriya benshi, ubushakashatsi n'iterambere rya filime ya EVA nabyo biriyongera, ndizera ko mu gihe cya vuba, filime ya EVA izagira iterambere rishya mu bijyanye n'imodoka, indege, n'ibirahure byo mu mazi.
