Method for testing the size of microbubbles
By adjusting the shading rate and scanning time of the gas-liquid mixture, combined with a stable flow state, the accuracy problem of microbubble particle size measurement was solved, enabling stable and accurate measurement of microbubble samples with different particle size ranges, while reducing testing time and material consumption.

Abstract
The present application relates to the technical field of micro-bubble testing, and discloses a testing method for micro-bubble granularity, which comprises the following steps: (1) performing granularity background testing by using liquid in a to-be-tested gas-liquid mixture I; (2) adjusting the volume ratio of gas to liquid in the to-be-tested gas-liquid mixture I to obtain a gas-liquid mixture II, and making the light-blocking rate of the gas-liquid mixture II be 5%-20%; (3) performing red light scanning on the gas-liquid mixture II for 5-10 seconds to obtain a preliminary testing result; (4) adjusting the testing time according to the preliminary testing result, and distributing the red light scanning time and the blue light scanning time to obtain a testing result; and (5) repeating the steps (1)-(4) to obtain the micro-bubble granularity in the to-be-tested gas-liquid mixture I. The testing method of the present application avoids the problem of inaccurate testing caused by serious overlapping and aggregation of bubbles, greatly improves the accuracy of testing, and has high repeatability.
