Working principle of medical air disinfection machine High-efficiency catalytic activated carbon is a commonly used air purification material.It is mainly used to absorb trace toxic gases in the air.The activated carbon used at ordinary times is mainly based on physical adsorption,Limited adsorption capacity,It is easy to cause secondary pollution.When the adsorption gas reaches saturation,Put it in a cleaner air,It is often the case that toxic and flavored gases that have been adsorbed are released again,The environment is polluted.Electrostatic adsorption and electronic dust collection use high voltage to ionize microorganisms to give charge,Adsorption by collecting plates.As the use time increases,The cumulative efficiency of contaminated particulate matter on the collection board decreased,It must be cleaned frequently (the maximum interval between normal use of the general environment must not exceed 90 days ).Negative ions, the use of high-volta

How often does laser chiller manufacturer filter change? Laser chiller manufacturersHow often does the filter change?The filter of the laser water-cooled machine can purify the impurities in the water-cooled machine, ensure the clean and clean of the circulating water quality in the water tank, filter out the impurities in the water, and ensure the smooth cleaning of the waterway system! It is an indispensable part of laser water cooler. If the water-cooled machine does not have a filter, the circulating water will slowly precipitate some impurities. in the long run, it will form dirt around the Q head and cavity of the laser, affecting the luminous quality of the laser machine, and there is dirty blockage, the water cycle is not good to cool it, and the time is long, which also affects the life and processing accuracy of the laser machine.The core part of the filter is the laser water-cooled filter element of the filter, which absorbs impurities in the filter water, so we must replace the filter element r
