How to Avoid Delamination When Edging Laminated Glass

How to Avoid Delamination When Edging Laminated Glass

Problem:

Some laminated glass manufacturers may face the problem: when they edging the laminated glass with Ethylene-vinyl acetate EVA Interlayer Film, the laminated glass delaminate at edges.

How to avoid this problem?

Reasons and Solutions:

1.Do not edging the laminated glass until the laminated glasses have been cooled for 24 hours after pulled out from the EVA GLASS LAMINATING OVEN.

2.When edging, SOME heat will be created in the edges, which will do harm to the EVA FILM adhesion, so please use more water to cool the heat when edging the laminated glass.

3.Please edging slowly and tenderly.

4.If the EVA FILM interlayer you use is not good quality, then the adhesive between the EVA Film and glass surface may be weak, then it’s easy to delaminate when edging.

Ethylene-vinyl acetate EVA Interlayer Film laminating PMMA acrylic sheet

Ethylene-vinyl acetate EVA Interlayer Film laminating PMMA acrylic sheet

Our company have invented a new product Ethylene-vinyl acetate EVA Interlayer Film for laminating Polymethylmethacrylate PMMA acrylic sheet.

The new type Ethylene-vinyl acetate EVA Interlayer Film can be processed at very low temperature, at about 75 degree which is lower than the soften point of Polymethylmethacrylate PMMA acrylic sheet.

When using Ethylene-vinyl acetate EVA Interlayer Film laminating PMMA acrylic sheet, you need to put two solid template up and down of the PMMA acrylic sheet to help vacuuming and avoid the PMMA acrylic sheet changing the shape.

PMMA acrylic sheet is light and great transparent, and is warmly popular in many indoor decoration implications.

Characteristics of Switchable Film (PDLC FILM, Magic Film, Smart Film)

Characteristics of Switchable Film (PDLC FILM, Magic Film, Smart Film)

pincible of the privacy glass

+ The translucent state of switchable film

The switchable film is composed by two transparent conductive film laminating with a polymer liquid core. And the polymer liquid core composes crystal ball and polymer. When the light pass through the PDLC FILM and reach the liquid crystal ball and polymer, the light is scattering. And the switchable film appears translucent.

+ The transparent state of switchable film

When electricity power is connected, the polymer-liquid crystal core is allowing light pass through, the switchable film appear transparent.

+ Haze of switchable film

To identify the switchable film quality, haze (the opposite is transparence ) is the key parameter to describe the switchable film. When the power is on, the switchable film should be as transparent as possible , when the power is off, the switchable film should be more haze.

+ View range of the switchable film

If the scattering is more, the view range is wide, the switchable film appears more haze.
