Precipitated silica leh fumed silica te inthlauhna ber chu particle size leh thianghlimna a ni.
Precipitated silica hi a tlangpuiin micrometer level-ah a awm a, fumed silica erawh chu a tlangpuiin nanometer level-ah a awm thung. Precipitated silica hian impurity content sang tak a nei a, purity chu a tlangpuiin 93% vel a ni a, fumed silica erawh chuan impurity content hniam tak leh thianghlimna 99% aia tam a thleng thei thung. Particle size leh thianghlimna inang lo tak tak avang hian fumed silica hian precipitated silica chu thickening, thixotropic, anti-settling, reinforcing, matting leh friction resistance-ah a phak lo hle.
