WINDOW FILM COATING EQUIPMENT
WINDOW FILM COATING EQUIPMENT
Window film coating equipment is a high-precision, high-performance vacuum coating equipment. It is also a equipment mainly used to deposit functional films on the surface of substrates such as polyester film (PET film). It can be used to produce thermal insulation film, explosion-proof film, one-way vision film, dimming film and other architectural and automotive window films.
What is window film?
It is a multi-layer functionalized polyester composite film material, which is pasted on the glass surface to improve the performance and strength of the glass, so that it has the functions of thermal insulation, thermal insulation, energy saving, explosion-proof, anti-ultraviolet rays, beautification of appearance, privacy avoidance, safety and safety protection.
The coating process of window film:
1.Slot Coating
Slot coating technology can coat window films with different structural formulations with good results. It can achieve high-speed continuous coating, the coating thickness is easy to control, the coating range can be adjusted freely, and it is convenient to disassemble and clean. The coating process has good anti-pollution performance and can maintain a high level of cleanliness.
2.Micro-gravure Coating
Micro-gravure coating can apply a thin coating on a thin substrate, with high coating uniformity and few defects. The wear of the scraper and anilox roller is small, and the micro-gravure roller is easy to replace. It is suitable for window film coating that requires high precision and high quality.
3.Process Control
The coating process of window films usually needs to be carried out in a clean room to ensure the stability of the production environment, including environmental cleanliness, temperature, humidity, and even attention to the matching of the temperature and humidity of the coating liquid and substrate with the production environment. At the same time, the manufacturing and installation accuracy of coating equipment, coating speed and tension control accuracy, uniformity of coating liquid, coating process parameters, and curing methods also affect the final product appearance and performance of the coating.
