Correlation Between the Number of Melt-blown Cloth Layers and the Salt-particulate Filtration Efficiency
In order to study the correlation between the number of melt-blown cloth layers and the salt-particulate filtration efficiency,the salt-particulate filtration efficiency of the melt-blown cloth that has different layers with the same material were measured,and been verified by testing many batches.The results show that the salt-particulate filtration efficiency of multi-layer melt-blown cloth is much higher than that of single-layer melt-blown cloth,but it don't show a simple cumulative relationship between the single-layer and the multi-layer of the particulate filtration efficiency.In addition,the penetration is a key influencing factor of particulate filtration efficiency of melt-blown cloth.A formula for the correlation between the number of melt-blown cloth layers and the salt-particulate filtration efficiency is established combined with the penetration.
