Development of air filter CCM rapid evaluation device
Development of air filter CCM rapid evaluation device---Baoji New Hiking Materials Supply Co.,Ltd.
Since 2016, New Hiking Air Filter Factory has developed a CCM rapid evaluation device for air filters, and established a 30-cubic warehouse for high-efficiency HEPA air filter particulate matter and a 3-cubic warehouse for testing formaldehyde. Test the ccm item of the air purifier filter, and conduct research on the relationship between the CADR of particulate matter and the primary filtration efficiency; the relationship between the primary filtration efficiency of the filter and the primary efficiency of the filter material; the relationship between the resistance of the filter material and the resistance of the filter; the cumulative purification amount of particulate matter and The relationship between the primary efficiency of the filter material and the resistance of the filter material.”
CCM value - Chinese means cumulative purification amount. Refers to the parameters of the cumulative purification capacity of the air purifier against particulate matter and gaseous pollutants under the specified test conditions. The straightforward description is: it describes the total weight of pollutants accumulated and filtered by the air purifier when the filtration capacity of the HEPA filter or the formaldehyde removal filter decreases to 50%, the unit is mg. The longer the net life. From the air filter industry, when designing the filter, we will measure the initial resistance of the filter. As time goes by, the dust on the air filter will increase and the resistance will increase. When the resistance level is two times, we determine that the air filter is scrapped (need to be replaced in time). The resistance at this point is what we call the final resistance. Therefore, the CCM value can also be understood as the service life of the filter.
The technical innovation of this project: the initial resistance efficiency and final resistance efficiency of the filter material can be tested to evaluate the cumulative purification capacity of the filter material, and the cumulative purification capacity of the filter material can be quickly evaluated. It can provide customers with estimated ccm suggestions in the early stage of research and development, and after the filter is completed, it can also be tested to adjust the plan faster.
