Filim kuleyl ah oo bir ahwaa baakad dabacsan oo isku dhafan oo la sameeyay iyadoo la adeegsanayo hab gaar ah si loogu dahaadho dusha sare ee filimka caagga ah lakab aad u khafiif ah oo aluminium bir ah, kaas oo habka ugu badan ee loo isticmaalo habka wax lagu dhejiyo ee aluminium vacuum, taas oo ah, aluminiumka birta ah ayaa dhalaaliya. iyo uumi-baxa heerkulka sare ee xaalad faaruq ah oo sarreeya, si uumiga uumiga ee kaydka aluminiumka ee dusha sare ee filimka caagga ah, si dusha sare ee filimka caagga ah uu leeyahay dhalaal macdan ah.Sababtoo ah waxay leedahay labadaba sifooyinka filimka caagga ah iyo birta, waa mid raqiis ah oo qurux badan, wax qabad aad u fiican iyo qalab wax lagu duubo.
Hoos waxaa ku yaal qaab ciyaareedkiisa:
1.Muuqashada
Dusha sare eefilim dahaarka ka hor birahawaa inuu ahaadaa mid siman oo siman, oo aan lahayn laalaab ama kaliya qadar yar oo ah suufka nool;ma jiro sinnaan cad, wasakh iyo adayg;ma laha calaamado, goobooyin, godadka iyo cilladaha kale;Ha ogolaan dhaldhalaalka cad, dusha Yin iyo Yang iyo ifafaale kale.
2. Dhumucda filimka birta ah
Dhumucdafilm laminating kulaylka aluminium waa in uu ahaado mid lebbisan, dhumucdiisuna way leexanaysaa talaabsanaanta iyo dhererka waa in ay ahaataa mid yar, qaybinta leexashaduna waa isku mid.Ma jiro feeraha convex cad oo durbaanka ah, haddii kale way fududahay in laalaabto marka la laminating.
3. Dhumucda aluminiumka
Dhumucda daahan aluminium waxay si toos ah ula xiriirtaa hantida xannibaadda eefilim isku dhafan oo bir ah.Iyadoo kororka dhumucda aluminiumka aluminiumka, gudbinta oksijiinta, uumiga biyaha, iftiinka, iwm, si tartiib tartiib ah ayaa hoos u dhacaya, oo u dhiganta, hantida xannibaadda ee filimka aluminiumka ah ayaa sidoo kale la hagaajiyay.Sidaa darteed, dhumucda lakabka aluminiumku waa inay buuxisaa shuruudaha caadiga ah, iyo daboolku waa inuu noqdaa mid la mid ah, haddii kale ma gaari doono saameynta xannibaadda ee la filayo.
4.Adhesion
Dahaarka aluminiumku waa inuu lahaadaa adhesion xoog leh iyo adkeyn wanaagsan, haddii kale way fududahay in la yareeyo oo ay keento dhibaatooyin tayo leh.Inta lagu jiro habka faakuumka tayada sare lehaluminium laminating filim, Qadar gaar ah oo xabagta asaasiga ah waa in lagu dabaqaa dusha aluminium ee filimka aluminiumka ah marka hore si loo hagaajiyo xoogga isku-xidhka ee u dhexeeya daaha aluminiumka iyo filimka substrate-ka, si loo hubiyo in aluminium aluminiumku uu yahay mid adag oo aan sahlanayn inuu dhaco. .Kadibna, lakabka dahaadhka aluminiumku waa in sidoo kale lagu dahaadhay laba qaybood oo polyurethane ah sida dahaarka sare si loo ilaaliyo lakabka aluminiumka in la damiyo.
5.Guryaha jirka iyo farsamada
Thefilim kuleyl ah oo laminating ahwaxay ku xiran tahay xoogga farsamada inta lagu jiro habka isku-dhafka ah, sidaas darteed waxaa loo baahan yahay in la yeesho awood farsamo oo gaar ah iyo dabacsanaan, waana in ay leedahay xoog jilicsan oo wanaagsan, dhererka, xoogga jeexjeexa, xoogga saameynta, caabbinta laalaabida fiican iyo adkaanta iyo sifooyinka kale si loo hubiyo in ay Ma fududa in la cajiiyo, la dumiyo, jaban iyo ifafaale kale inta lagu jiro habaynta isku dhafan.
6.Qoyaanka ka bixi kara
Gudbinta qoyaanku waxay tilmaamaysaa dabar-goyntaaluminium EVA adhesion filmbiyaha uumiga ku jira xaalado gaar ah, taas oo ka tarjumaysa iska caabbinta qoyaanka ee aluminium kulaylka filimka laminating ilaa xad.Tusaale ahaan, qoyaanka qoyaanka ee 12 um polyester metalized film lamination film (VMPET) waa inta u dhaxaysa 0.3g /㎡ · 24h ~ 0.6g /㎡ · 24h (heerkulka 30 ℃, qoyaan qaraabo 90%);Dareemka qoyaanka ee filimka aluminium ee CPP (VMCPP) oo leh dhumucdiisuna tahay 25 um waa inta u dhaxaysa 1.0g /㎡ · 24h iyo 1.5g /㎡ · 24h (heerkulka 30 ℃, qoyaan qaraabo 90%).
7.Ogsajiin dareema
Dareemidda oksijiinta waxay ka dhigan tahay qadarka gelitaanka oksijiinta filimka aluminiumka kulaylka aluminium ee xaaladaha qaarkood, taas oo ka tarjumaysa xajmiga xannibaadda filimka kulaylka kuleylka ah ee oksijiinta, sida qulqulka oksijiinta ee aluminiumka polyester-ka hore ee dahaarka leh dhumucdiisuna tahay of 25 um waa qiyaastii 1.24 ml/㎡·24h (heerkulka 23℃, qoyaan qaraabo ah waa 90%).
8.Baaxadda xiisadda dusha sare
Si loo sameeyo khad iyo koollo isku dhafan ayaa leh qoyaan wanaagsan oo ku dhejisan dusha sare ee filimka aluminiumka ah, waxaa loo baahan yahay in xiisadda dusha sare ee filimka hore ee birta ah ee dahaarka ah ay gaarto heer go'an, haddii kale waxay saameyn doontaa adhesion iyo ku dhejinta khad iyo koollada dusha sare, sidaas darteed saameynaya tayada daabacaadda iyo alaabta isku dhafan.Tusaale ahaan, xiisadda dusha sare ee polyesterkaaluminium kuleyl filim lamination(VMPET) ayaa looga baahan yahay inuu gaaro in ka badan 45 dynes, ugu yaraan 42 dynes.
