Application of Precipitated Silica in Print Coated Paper Coating

Abstract:

In is paper precipitated silica is used in coated paper coating. It shows that the effect of different silica on properties of pigment dispersion is different. The dosage of silica influences the properties of pigment dispersion too. The viscosity of coating is higher than the corresponding pigment dispersion. The higher the viscosity of pigment dispersion is, the higher the corresponding viscosity of coating is. The more the dosage of silica is and the littler the particle size of silica is, the larger water retention value of coating is. When the precipitated silica is used in coated paper coating, the viscosity of coating is increasing. If precipitated silica coat paper, the whiteness of coated paper increases by 1%-2%
