The Difference Between Dry and Wet Laminated Glass

Laminated glass is made of two or more pieces of sheet glass with one or more layers of organic polymer interlayer film interposed between the float glass and the middle after special high temperature pre-pressing (or vacuuming) and high temperature and high pressure processing. The film is permanently bonded to a composite float glass product. Even if the sheet glass breaks, the pieces will stick to the film, and the broken flat glass surface will remain clean and smooth. This effectively prevents the occurrence of debris pitting and penetrating fall events, ensuring personal safety. This type of float glass is mostly used in the roof of the sun.

Dry laminated glass is a standard that utilizes the hot-melt type of eva film and the vacuum negative pressure of the vacuum pump to bond the flat glass to the flat glass to achieve the safety glass. EVA film has strong environmental stress resistance, cracking resistance, moisture resistance, weather resistance, heat sealing and so on. It is precisely because of these qualities of EVA that it has been an important milestone in the development of domestic EVA laminated glass interlayer film since 2008. This period presents a clear trend: the country requires that the dry laminated glass used in the construction of laminated glass can use eva film and pvb film. Dry laminated glass uses eva film, which is a one-step lamination. The operation is simple, there is no requirement for the environment, the weather and the temperature, and the investment is less recycled!

Wet laminated glass is a glue-filling method using liquid glue, but the glass safety fastness is not as good as dry-filling. The volatility of the liquid glue and the contact between the human body and the wet glue are both harmful, and the weather resistance of the wet laminated glass is not as good as that of the dry laminated glass. The filling method is also affected in the rainy days, so the small investment Fang Ding Building EVA rubber furnace is favored by the majority of customers.
