Brief introduction: Bubble generation process and has the nature of bubbles in the test liquid foam with the same importance. The commonly used method to generate foam, is in the process of industrial production injection gas to the sample and stirring; Only when the process can be under repeatable conditions, to ensure that there is comparable results. Like stability, drainage, humidity and air bubble structure parameters, such as that associated with bubbles. Foamability, foam stability and instability, by using optical sensor measurement of foam height or the volume to decide. The drainage behavior of transparent samples, can also be measured in this way. Because they are almost the same size, height measurement is not suitable for the stability of the bubble. Other unstable standards, therefore, the development, representative is a liquid containing bubbles, its gravity drainage changes to be recorded by measuring the conductivity. In addition, you can from the bubble structure to assess foam stability. Using image recognition method alone, also can measure of bubbles. Diffusion between foam bubbles (ostwald ripening), and the diffusion between foam drying process (drainage), can be observed from the size and shape of the bubble. Technical parameters: Specification: 690 * 310 * 480 mm Gas flow: 0-500 - ml/min, pump pressure 1.5 MPa Foam height: by means of video collection, measuring height of 0-300 - mm Liquid volume: testing liquid 20 ml sample minimum volume Conductance: foam pipe have 5 road conductance measurement of electrical conductivity, conductance resolution of 0.01 us/cm Temperature control: built-in heating rods, controllable temperature 0-80 degrees Video systems: 8 times telephoto lens, 1.3 million pixel digital camera Voltage: 220 v Power: 300 w
