Desulfurized gypsum light through-pore ceramsite

Abstract

The invention discloses a desulfurized gypsum light through-pore ceramsite. According to the technical scheme, the desulfurized gypsum light through-pore ceramsite is characterized by being prepared from desulfurized gypsum, high-viscosity attapulgite, a powdery attapulgite foaming agent, activated clay residues, floating beads, light magnesium oxide, expanded perlite, expanded vermiculite and quick lime. The materials of the desulfurized gypsum light through-pore ceramsite are subjected to stirring and mixing, extruding granulation, drying, roasting, heat preservation and screening, and then packaged into the desulfurized gypsum light through-pore ceramsite in a sealed mode. The desulfurized gypsum light through-pore ceramsite has the advantages that the desulfurized gypsum light through-pore ceramsite is large in specific area, small in bulk density, high in water absorption, excellent in breathability, attractive in appearance molding, free of peculiar smells, light and good in strength, and micropores and macropores are integrated; when the desulfurized gypsum light through-pore ceramsite is used for culturing or planting various nursery stocks, flowers and vegetables, the roots of plants can absorb water or nutritional ingredients of liquid fertilizer from the desulfurized gypsum light through-pore ceramsite, and thus it is ensured that the plants grow and develop well and are high in survival rate; the desulfurized gypsum light through-pore ceramsite is suitable for preparing soilless culture media and nutrient soil.

Description

technical field [0001] The invention relates to ceramsite, in particular to a desulfurized gypsum lightweight through-hole ceramsite. Background technique [0002] The soil used for cultivating or planting various seedlings, flowers and vegetables is mostly made of nearby soil, and then mixed with some plant ash or peat soil. The moisture content of these soils is 12-20%, and contains a large amount of harmful bacteria. [0003] When using these soils to cultivate or plant various seedlings, flowers and vegetables, it is difficult to control the amount of water in the later stage. After water replenishment, the soil moisture content exceeds 30%, and the moisture content in the soil is relatively high, and the soil will be semi-fluid. If the soil is not replenished in time, the soil will appear compacted and hard, which will directly affect the normal growth of plants. [0004] With the continuous improvement of the quality requirements of greening projects, materials such ...

Problems solved by technology

[0009] After roasting, the internal structure of the spherical ceramsite is tighter. Although the strength of the spherical ceramsite is relatively high, the effective specific surface area is small, and the specific gravity and bulk density are relatively large, thereby reducing the adsorption capacity and water absorption of the spherical ceramsite.
