Preparation process of ceramsite with high strength and hydrophobicity
The invention discloses a preparation process of ceramsite with high strength and hydrophobicity. The preparation process comprises the steps of raw material preparation, raw material drying, grinding, primary stirring and secondary stirring and auxiliary material adding. The preparation process has the beneficial effects that the grain rolling time is lengthened by firstly nucleating coarse powder and then adding fine powder in the granulation process; the product properties are improved through multiple times of different-temperature firing processes; the aim of waste utilization is achieved; auxiliary materials MnO2 and TiO2 in different ratios are added and are respectively used in the coarse material and the fine material so as to improve the properties of the ceramsite, such as strength; hydrophobic process treatment is also adopted, thus obviously reducing the water absorption of the ceramsite; multiple times of different degrees of firing processes are respectively adopted in the firing process to improve the sintering strength and properties; and the preparation process has the effect of increasing the density, strength and hydrophobicity of the ceramsite and is smooth in spherical grain surfaces and quite good in effects.
