The clarity, image stability and continuity, color authenticity and other factors of water screen film are determined by the quality of water screen generator and water screen. Water curtain film has the following basic requirements for water curtain quality:
1, water curtain generator water curtain fan, composed of dense area and discrete region water curtain curtain. The video image projected on the dense water curtain area imaging, so the radius must be larger than the screen size.
2, dense water curtain area must consist of fine droplets of uniform size, diameter of water shoots into 0.5mm, water distribution must be tight and no gap.
3. The thickness of water curtain is one of the important indexes of water curtain stability. It should not be too thick or too thin. Excessive thickness may cause 2 imaging, leading to blurring and distortion of the screen. It is too thin to be affected by the wind, or the water screen is broken, which affects the quality of the picture.
4, the water curtain should be adjacent to the surface of the water and vertical to the water surface, so that the image is like moving on the ground or on the surface of the water, a strong sense of three-dimensional, and more close to life.
5, in the natural water bodies (such as reservoirs, lakes, Jiang He) on the production of water curtain, the water curtain generator should be able to rise and fall with the rise and fall of water levels.
