1, in the vacuum system, water vapor is the biggest obstacle that affects the pumping speed of the vacuum device, the cryotrap pump can quickly and effectively capture 65% to 95% of the water vapor in the residual air of the system, reducing the time spent on pumping steam, and the efficiency is as high as 80%. Adding a cryogenic capture pump to an existing vacuum system can increase production capacity by 30% to 100% and improve coating quality.
2, in the vacuum system, water vapor is the biggest source of pollution, so in the higher coating quality, if you can get a lower partial pressure of steam, you can enhance the adhesion of the film, improve the coating quality, avoid color difference in the process of evaporation of various decorative materials, in the process of evaporation of plastic substrate can make the corner surface is uniform.
