GAMA玻璃PVB膠合程序 1.合片 Placing 在二塊已洗淨並乾燥的玻璃之間, 將中間膜置 于其中。合片作業應注意事項如下:●避色含水率變化最好在恆溫恆濕( 建議 25 ℃, 相 對溼度23%)的房間內進行。避色含水率變化最好在恆溫恆濕( 建議 25 ℃, 相 對溼度23%)的房間內進行。 ●中間膜與玻璃的溫度應儘量一致,以避免兩者溫差 太 大 而 導 致 空 氣 不 易 排 除 造 成 粘 合 或 收 縮 不良。 ●應避免任何的機械拉伸。 ●避免外物污染中間膜及玻璃。 The PVB film is placed between washed and re-dried glass. The points for attention: ● The process should be done in a room with constant temperature and humidity (suggested condition:25℃ and RH23%) . ● The temperature of P V B film a n d g l a s s should be close. If not, the air may not be exhausted easily and lead to bad adhesion or contraction. ● Any mechanical stretch should be avoided. ● Any pollution of glass and PVB film should be avoided. 2.預壓合 Pre-pressing 預壓合工程主要目的如下:●將玻璃和中間膜之間的空氣排出。 ●促進玻璃與中間膜間的密著性。 ●夾層玻璃邊緣的密封,以避免在正壓合時,空氣 浸入夾層玻璃中。 The purposes of pre-pressing, ●Air discharge between the glass and PVB film. ●Promoting the adhesion between the glass and PVB film. ●To seal the edge of laminated glass so that the air permeation to laminated glass in autoclave could be avoided. 預壓程序主要二種工法:壓輪法與真空法。壓輪法主要應用於平板夾層玻璃的製造, 以「一加熱室二壓輪法」為例,建議操作條件請參考下表。 壓輪法: 主 要 應 用 於 平 板 夾 層 玻 璃 的 製 造 , 以 「 一 加 熱 室/二壓輪法」為例,建議操作條件請參考下表。 There are two main methods for pre-pressing: ■ Nip Roll System This process is usually applied on flat laminated glass. Our suggested conditions for “one oven/ two nip roller process” are as the table below. 真空法:Vacuum System 主要應用於彎曲夾層玻璃的製造,又分兩種設備: 膠袋法與圈環法。 請參考下列建議操作條件This process is for bent laminated glass. There are two kinds of equipment: vacuum bag method and vacuum ring method. The Operation conditions of the two methods are Suggested as the below table. 3.正壓合 Autoclave Process 正 壓 合 程 序 一 般 使 用 氣 壓 式 或 油 壓 式 的 高壓釜。 單層中間膜夾層條件, 請參考下表與溫度( 壓力)-時間關係圖。Generally, an air type or oil type autoclave is used in this process. The suggested Conditions of autoclave process for single interlayer film laminating are as Following Table and figure |
