It is understood that aerosol is a commonly used gas leak detector, which is used to detect whether there is leakage in pipelines, valves, pumps, storage tanks, etc. Aerosols usually use freon substances, which can quickly diffuse and penetrate into tiny leakage points and form white smoke around them, which is convenient for detection. Usually, the residence time of aerosol in leak detection equipment is very short, usually only a few minutes to half an hour. This mainly depends on the speed of smog diffusion and the temperature and humidity of the surrounding environment. Before using aerosol to detect the leakage of equipment, it should be determined whether the equipment is in normal operation and all valves in the system should be closed to ensure that all gases are fixed in the pipeline and equipment system. Then spray the aerosol on the equipment, observe whether there is white smoke around and judge whether there is leakage.

After testing, the residual aerosol should be removed in time, and the equipment should be maintained and repaired. In addition, aerosol should be stored in a dry, cool and well-ventilated environment to ensure its quality and use effect.
