In the production of a PET protective film, a polyester film (PET) is used as the material, and a single-sided coating of silica gel water forms a single-layer PET protective film, thereby playing the roles of anti-corrosion, insulation, and decoration. Currently, in the process of coating silica gel water on the film, most of the work is done by brushing the silica gel water onto the film with a brush. According to the coating trajectory of the brush, the position brushed first has a longer contact time with air than the position brushed later. And the silica gel water mainly combines with water molecules in the air to undergo a curing process. Therefore, due to the different contact times of the silica gel water with air, it is easy to cause different adhesion forces of the silica gel water brushed on the film, seriously affecting the quality of the geomembrane and being inconvenient in actual work.
