: G5 i* {! I, @tvb now,tvbnow,bttvbAdding a small amount of electret masterbatch PPH-57ZJ can increase the density and depth of the charge trapping energy trap in the melt-blown non- woven fabric, effectively release negative ions and store charge, and improve the comprehensive filtration effect and thermal attenuation of the melt-blown non-woven fabric Performance. In the case of the same fiber fineness and gram weight, it can reduce the resistance of the melt-blown non-woven product, and at the same time improve the filtration effect of the melt- blown non-woven product.
