Filimka EVA waa nooc ka mid ah filim viscosity sare leh oo laga sameeyay polymer resin (ethylene-vinyl acetate copolymer) oo ah walaxda ugu weyn ee ceeriin ah, isagoo ku daraya waxyaabo gaar ah iyo farsamayn qalab gaar ah. Iyadoo cilmi-baaris iyo horumarin joogto ah lagu sameeyay filimka EVA, filimka EVA wuxuu sii wadaa inuu bislaado, filimka EVA ee gudahana wuxuu noqday mid laga dhoofiyo soo dejinta.
Dad badan ayaa u maleynaya in filimka EVA loo isticmaali karo oo keliya qurxinta gudaha, laakiin tan iyo 2007, Shandong Fangding Safety Glass Technology Co., Ltd (Kahor Fangding Technology Co., Ltd.) ayaa si guul leh u codsatay shahaadada CCC, taasoo muujineysa in filimka EVA uu buuxiyo shuruudaha qaranka ee galaaska injineernimada dibadda marka loo eego xoogga, hufnaanta ama dhegdhegga. Tan iyo markaas, waxay jebisay doodda ah in PVB uu yahay qalabka keliya ee qalalan ee loo isticmaalo injineernimada dibadda ee Shiinaha.
Fiilada EVA ee codsiyada injineernimada bannaanka:
★ Bishii Maarso 2009, waddanku wuxuu bilaabay inuu sameeyo, bishii Maarso 2010, si rasmi ah loo sii daayay heerka muraayadda la dahaadhay ee qaranka ayaa qeexaya in filimka PVB loo isticmaalo muraayadda baabuurta. Dhismaha muraayadda la dahaadhay, sida balakoonka ilaalada, saqafka nalalka, daaqadaha ganacsiga, derbiga daahyada galaaska, PVB iyo filimka EVA ayaa la isticmaali karaa.
Iska caabbinta iftiinka EVA, ka-hortagga biyaha, iska caabbinta cimilada, iska caabbinta daxalka, saameynta ka-hortagga buuqa ayaa ka wanaagsan PVB, oo ay weheliso kaydinta fudud, tignoolajiyada farsamaynta fudud, hawlgal habboon, iyo kharash yar, shirkado badan ayaa aad ugu janjeera EVA.
Qof kasta oo warshadaha ku jira wuu ogyahay in marka autoclave-ku uu yahay muraayad la dahaadhay oo qaloocan, ay lagama maarmaan tahay in bacaha silikoon loo isticmaalo kahor-vacuum-ka, iyo shirkado qaar si loo badbaadiyo kharashyada, iyadoo hore loogu faaruqinayo bacaha balaastikada ah ee la tuuri karo, ka dibna lagu shubayo autoclave-ka, kaas oo aad u dhib badan kharashkuna uu sarreeyo.
Laakiin foornada dahaarka ee EVA ayaa xallisa dhibaatadan: muraayadda dahaarka leh ee qaloocan waxaa la gelin karaa foornada si loo sii wado cadaadiska ka hor, ka dibna loo geliyo qalabka otomaatiga ah. Hadda, iyadoo la horumarinayo tiknoolajiyada, Fangding Technology Co., Ltd. waxay soo saartay qalab muraayad dahaar leh oo qaloocan oo hal mar la qaabayn karo, taasoo si weyn u badbaadinaysa waqtiga iyo kharashka.
Isticmaalka filimka EVA ee muraayadda qurxinta:
Muraayadaha farshaxanka sida siligga, dharka, warqadda sawirka, iyo xoojinta hal lakab waa in lagu sameeyaa filimka EVA, gaar ahaan muraayadda farshaxanka cusub oo leh walxo dhab ah oo dhexda ku yaal, sida ubaxyo dhab ah iyo caws caws ah. Hadda nooca muraayadda farshaxanka heerka sare ah ayaa inta badan la dhoofiyaa.
Adeegsiga filimka EVA ee muraayadda tamarta cusub:
Adeegsiga filimka EVA ee tamarta cusub waxaa inta badan ka muuqda muraayadaha qorraxda ee loo yaqaan 'solar photovoltaic panels', galaaska korontada, galaaska iftiinka iyo wixii la mid ah. Soo saarista muraayadaha qorraxda ee loo yaqaan 'solar photovoltaic panels' waxaa laga sameeyay silicon wafer iyo loox wareeg ah oo leh isku-darka filimka EVA, oo badanaa laga sameeyay mashiinka laminating; galaaska korontada ee caadiga ah waxaa laga dhigi karaa mid gudbiya iyadoo lagu dahaadho filim gudbiye (filim ITO) dusha sare ee galaaska caadiga ah. Hadda galaaska korontada ku shaqeeya waa galaas la dahaadhay oo laga sameeyay filimka EVA iyo filimka gudbiye, qaar ka mid ah galaaskana waxaa sidoo kale lagu dhejiyay LED, kaas oo ka qurux badan oo deeqsinimo badan.
Muraayadda la beddeli karo waa nooc cusub oo ah walxo gaar ah oo galaas sawireed ah kaas oo filimka dareeraha ah ee kiristaalka iyo filimka EVA ku dhex daraya laba lakab oo galaas ah, ka dibna sameeya qaab-dhismeedka is-dhexgalka ka dib heerkul iyo cadaadis gaar ah. Hadda muraayadda tamarta cusub ee laga sameeyay filimka EVA ayaa si weyn loogu isticmaalay goobaha ganacsiga iyo kuwa dadweynaha iyo guryaha qoyska labadaba.
Kaalinta filimka EVA ee muraayadda warshadaha:
Muraayadaha albaabka qaboojiyaha iyo mashiinka dharka lagu dhaqo ee hadda jira waa muraayad la qaboojiyey, agab gaar ah oo qiyaastii 3.2mm ah oo leh filimka EVA ayaa lagu tuujiyaa heerkul sare, kaas oo ah mid qurux badan oo ammaan ah.
Si loo daboolo baahiyaha macaamiil badan, cilmi-baarista iyo horumarinta filimka EVA ayaa sidoo kale sii kordheysa, waxaan aaminsanahay in mustaqbalka dhow, filimka EVA uu sidoo kale yeelan doono horumarro cusub oo ku saabsan baabuurta, duulista hawada, iyo galaaska badda.
