The cleaning effect of ultrasonic cleaning machine is generally the best at 30℃-40℃, and the higher the temperature of cleaning solution, the more obvious the effect is. Usually, when the ultrasonic cleaning machine is actually used, the most suitable cleaning temperature is 40-60℃, especially in cold weather, if the temperature of cleaning solution is low, the cleaning effect is poor.
Therefore, some cleaning machines wrap electric heating wires around the cleaning drum to control the temperature. When the temperature rises, cavitation effect is easy to occur, so the cleaning effect is better. When the temperature continues to rise, the gas pressure in the cavity increases, which leads to the decrease of the impact sound pressure, reflecting the multiplication of these two factors.
