Example Embodiment
[0020] Example 1:
[0021] The visualization system consists of 1 camera, 2 light sources, 3 light-shielding plates, 8 light-transmitting grooves, 4 condensers, 5 particle containers, observed fluid and display particles, and an installation platform 7. The installation structure is shown in Figure 1. The light source 2, the condenser 4 and the camera 1 can be moved on the platform 7 to obtain the best lighting and imaging effects. It shows that the particles are mixed uniformly with 80g206 polystyrene, 10g nylon and 10g phosphor, heated at 210℃ to fully fuse, and then pelletized by a pelletizer. The particle diameter is 0.8mm and the density is 1.05g / cm. 3 . The fluid medium is water, plus edible salt to adjust the density to 1.05g / cm 3 . The fluid is contained in a glass beaker with a diameter of 120mm and a height of 160mm. A light-shielding plate 3 is added in front of the ultraviolet light source 2, and the light-shielding plate 3 is provided with a light-transmitting slot 8 ...
