PE glass film is widely used, not only in glass, but also in other uses, but our understanding of this product is not very comprehensive, for example, about the drying process of PE glass film adhesive, it will have a greater impact on the quality of PE protective film. The drying process of glass film adhesive refers to the process of volatilizing the solvent or water in the adhesive layer coated on the substrate to make the adhesive solidify. Because it always takes a certain time for solvent or water to volatilize, drying is a relatively slow step in the production process of protective film. The drying speed not only determines the production speed, but also affects the product quality to a great extent.

Once the adhesive of PE glass film is coated, the solvent will volatilize quickly before it is put into the dryer oven. When the protective film enters the oven, the heat absorbed by the solvent volatilization is supplemented by the heat transferred from the outside. When the heat reaches equilibrium, the surface temperature of the adhesive layer and the volatilization rate of the solvent can also be kept constant. The viscosity and other rheological properties of PE glass film adhesive are also factors affecting the coating process of protective film. The larger the rheological properties of adhesive deviate from Newtonian fluid, the more prone to various quality problems in the coating operation. Especially when the adhesive presents the properties of expansion body, because its viscosity will increase rapidly with the increase of coating speed in the coating process, it is necessary to use relatively high viscosity The larger the mechanical force, the more difficult it is to get uniform coating.


In the actual operation process, increasing the temperature of the oven can certainly increase the diffusion speed of the solvent, but too high temperature is often easy to make the adhesive layer foaming, which will also increase the risk of fire. Therefore, in order to produce high-quality PE glass film products, it is necessary to make the quality of the substrate, the quality of the adhesive and the production process meet the requirements.


When pasting PE glass film to the car, we should first pay attention to the explosion-proof function of the protective film. Excellent explosion-proof protective film has strong resistance. High quality PE glass film, whose UV isolation rate can reach 100%, can effectively prevent people in the car from being exposed to excessive UV light, and burn the skin; at the same time, it can also maintain the car audio from being damaged by the sun, which is also one of the factors to measure the service life of PE glass film.
