Black and dirty spots phenomenon before Glass lamination processingBlack and dirty spots phenomenon
In the production process of the EVA foil,it is caused by carbonization of some components due to the high temperature,or the EVA film is contaminated during the production process.
Electrostatic adsorption when combining EVA foils
Due to the static electricity of the EVA foil itself,it is easy to absorb dust and hair when processing the EVA foil.
Method:Use absolute ethanol to wipe clean the black spots and dirty spots on the surface of the EVA foil and glass when combining the EVA foil.
Install a set of fluorescent lamps under the EVA foil operation table to make it easier to find black spots,dirty spots,hair,etc.
