Application of diatoms in filling materials
Abstract
Make full use of the resource advantages of the large tableland diatomite ore clay. Comprehensive development of the application of raw ore clay in filling materials. The ore clay has the characteristics of high SiO2, less impurities, fine, loose, light weight, porous, water absorption and permeability. Large porosity, strong adsorption, sound insulation, wear resistance, heat, and has a certain strength, so it is widely used in dental impression materials, masks, paints, plastics, rubber, toothpaste, paper, asphalt, etc.
