Filimka EVA waa nooc ka mid ah maaddada filimka viscosity-sare leh oo laga sameeyay resin polymer (etylene-vinyl acetate copolymer) oo ah sheyga ugu weyn ee ceeriin, isagoo ku daraya waxyaabo gaar ah oo lagu daro qalab gaar ah.Iyadoo cilmi baarista joogtada ah iyo horumarinta filimka EVA, filimka EVA wuxuu sii wadaa inuu qaan-gaaro, filimka EVA ee gudaha wuxuu noqday dhoofinta laga soo dhoofiyo
Dad badan ayaa u maleynaya in filimka EVA loo isticmaali karo oo kaliya qurxinta gudaha, laakiin tan iyo 2007, Shandong Fangding Safety Glass Technology Co., Ltd (Hore ee Fangding Technology Co., Ltd.).ayaa si guul leh u codsatay shahaadada CCC, taas oo muujinaysa in filimka EVA uu buuxiyo shuruudaha qaranka ee muraayadda injineernimada dibadda ee xoogga, daah-furnaanta ama adhesion.Tan iyo markaas, waxay jebisay dooda in PVB ay tahay isticmaalka kaliya ee qalalan ee loo isticmaalo injineernimada dibadda ee Shiinaha.
Filimka EVA ee codsiyada injineernimada dibadda:
Bishii Maarso 2009, waddanku wuxuu bilaabay inuu sameeyo, Maarso 2010, siideynta rasmiga ah ee heerka dhalada dahaadhka ah ee qaranka wuxuu dhigayaa in filimka PVB loo isticmaalo galaaska baabuurta.Iyo in la dhiso muraayado dahaaran, sida ilaaliyaha balakoonka, saqafka nalka, daaqadaha ganacsiga, gidaarka daahyada, PVB iyo filimka EVA waa la isticmaali karaa.
Iska caabbinta iftiinka EVA, hydrophobicity, caabbinta cimilada, iska caabinta daxalka, saamaynta ka-hortagga qaylada ayaa ka fiican PVB, oo lagu daray kaydinta fudud, tignoolajiyada fudud ee fudud, hawlgal ku habboon, iyo kharash yar, shirkado badan ayaa u janjeera EVA.
Qof kasta oo ka mid ah warshadaha waa ogyahay in marka autoclave waa qalooca galaas laminated, waxaa lagama maarmaan ah in la isticmaalo bacaha silikon for pre-vacuuming, iyo qaar ka mid ah shirkadaha si loo badbaadiyo kharashka, pre-vacuuming bacaha caag ah la tuuri karo, ka dibna galay autoclave ah. aad ayuu u dhib badan yahay qiimuhuna waa sarreeyaa.
Laakiin foornada lamination ee EVA ayaa xallisa dhibaatadan: muraayadda qalooca leh ayaa lagu dhejin karaa foornada si loo cadaadiyo horay, ka dibna autoclave.Hadda, iyada oo horumarinta tignoolajiyada, Fangding Technology Co., Ltd. waxay samaysay qalab muraayado ah oo qalloocan oo hal mar la qaabayn karo, kaas oo si weyn u badbaadiya wakhtiga iyo kharashka.
Codsiga filimka EVA ee muraayadda qurxinta:
Muraayadaha farshaxanka sida silig, dhar, warqad sawir, iyo xoojinta lakabka kaliya waa in lagu sameeyaa filimka EVA, gaar ahaan muraayadda farshaxanka cusub ee walxaha dhabta ah ee dhexda ah, sida ubaxa dhabta ah iyo cawska cawska.Hadda nooca muraayadda farshaxan ee heerka sare ah ayaa inta badan la dhoofiyaa.
Codsiga filimka EVA ee muraayadda tamarta cusub:
Codsiga filimka EVA ee tamarta cusub ayaa inta badan ka muuqda muraayadaha sawir-qaadista ee qorraxda, muraayadaha wax-qabadka, dhalooyinka khafiifinta iyo wixii la mid ah.Wax soo saarka muraayadaha iftiinka qoraxda waxaa laga sameeyaa wafer silikoon iyo guddi wareeg ah oo leh filim EVA ah oo isku dhafan, oo inta badan laga sameeyay mashiinka dhejiska;Muraayadaha korantada ee caadiga ah waxaa laga dhigi karaa mid dhaqdhaqaajiya iyadoo lagu dhejiyo filim conductive ah (filim ITO) oogada muraayadda caadiga ah.Hadda muraayadda korantada ayaa ah muraayad dahaadh laga sameeyay oo laga sameeyay filim EVA ah iyo film conductive ah, sidoo kale galaasyada qaar waxa lagu daraa LED, taas oo ka qurux badan oo deeqsinimo ah.
Muraayada la beddeli karo waa nooc cusub oo ah alaabada dhalada korantada ee gaarka ah kaas oo isku xira filimka crystal dareeraha ah iyo filimka EVA ee dhexda laba lakab oo galaas ah, ka dibna qaabeeya qaabdhismeedka isdhexgalka ka dib heerkul iyo cadaadis gaar ah.Hadda muraayadda tamarta cusub ee laga sameeyay filimka EVA ayaa si weyn loogu isticmaalay ganacsiga iyo goobaha dadweynaha iyo guryaha qoyska.
Wax ku darsiga filimka EVA ee muraayadaha warshadaha:
Muraayada albaabka qaboojiyaha hadda jira iyo muraayadda mashiinka dharka lagu dhaqo ayaa asal ahaan dhalaalaysa iyo qalab gaar ah oo ku saabsan 3.2mm oo leh filimka EVA ayaa la isku tuujiyaa heerkul sare, kaas oo labadaba qurux badan oo ammaan ah.
Si loo daboolo baahida macaamiisha badan, cilmi-baarista iyo horumarinta filimka EVA ayaa sidoo kale sii kordhaya, waxaan aaminsanahay in mustaqbalka dhow, filimka EVA uu sidoo kale yeelan doono horumarro cusub oo baabuurta, duulista, iyo muraayadaha badda.
