PEFA F Grain & Micro Powder: Chemical Composition And Particle Size Composition Standard
Product Advantages
1.Low sodium and micro sodium WFA can be provided. Na2O of our micro sodium WFA is less than 0.1%, can be double 0.
2.High cleanliness, strong adhesion, high hardness and strong cutting force, whiteness can be based on customer needs.
3.High bulk density and high transparent wear-resistance sands can be provided. The crystal is rounder than normal ball mill WFA.
4.Various specifications can be supported, and the bulk density can be adjusted according to customer’s demand.
