1. In the vacuum system, water vapor is the biggest obstacle to the pumping speed of the vacuuming device. The Tianhan-135°C water vapor trap can quickly and effectively capture 65 to 95% of the water vapor in the residual air of the system, reducing the steam vapor. The time it takes is up to 80%. If the Tianhan-135°C water vapor trap is installed in the existing vacuum system, the production capacity can be increased by 30% to 100%, and the coating quality can be improved. 2. In the vacuum system, water vapor is the biggest source of pollution. Therefore, in the higher coating quality, if a lower vapor partial pressure can be obtained, the adhesion of the film layer can be enhanced, and the coating quality can be improved. The color difference is avoided during the process of decorating the material, and the corner surface is evenly flat during the evaporation process of the plastic substrate. The working principle of the water vapor trap : a refrigeration coil that can reach below -120 °C , placed in the vacuum chamber or the pump port of the oil diffusion pump, rapidly traps the residual gas of the vacuum system through the low-temperature condensation effect on the surface . This greatly shortens the vacuuming time (60-90% of the pumping time can be shortened) and a clean vacuum environment (the vacuum can be increased by half an order of magnitude to 10-8 Torr, 10-5 Pa).
