Abstract:

The particle size distributions and morphologies of two self-prepared superfine materials,that is,the SH-perfine heavy calcium carbonate powder and the PVC plastic membrane modified with superfine heavy calcium car-bonate powder,were investigated by means of the photon-detecting analytics.The corresponding results are then compared with those obtained by the traditional micro.zone analytics.SEM.The results indicate that the photon detection with dynamic light scattering is suitable for the analysis of particle size distribution of sub-micro superfine materials,while the laser condensing and focusing scanner with plane digital image are more suitable for the investigation of the dispersion of superfine material in plastic,as compared with SEM.Thus,a new analytical method is proposed for the investigation of surface properties of superfine materials.
