Product introduction

Sodium stearate was selected as surface modifier to carry out wet surface modification of nano magnesium hydroxide. In order to investigate the modification effect, the specific surface area, sedimentation rate, oil absorption value and viscosity in dispersion medium (such as liquid paraffin) were measured before and after modification. It is found that the dispersion of magnesium hydroxide particles is greatly improved and the specific surface area is increased; The surface of nano magnesium hydroxide was modified from hydrophilic surface to hydrophobic surface. The dispersion of particles in different media is an important measure to characterize this performance; The oil absorption value of modified nano magnesium hydroxide powder decreased significantly. The dispersion of modified nano magnesium hydroxide powder in soft PVC system is better than that of unmodified powder.
