Illite smectite mixed layer clay lightweight through-pore ceramsite

Abstract

The invention discloses illite smectite mixed layer clay lightweight through-pore ceramsite. The technical scheme is characterized in that the ceramsite is composed of illite smectite mixed layer clay, high-viscosity attapulgite clay, a powdery attapulgite foamer, activated carclazyte residue, floating beads, light magnesium oxide, expanded perlite, expanded vermiculite, ferrous sulfate and quicklime. The ceramsite is prepared by subjecting materials to stirring and mixing, extruding and granulating, drying, calcining, temperature holding, screening and sealing and packaging. The ceramsite has the advantages of large specific surface area, small bulk density, high water absorption rate, excellent air permeability, attractive appearance, freeness of peculiar smell, high lightweight strength and integration of micropores and macropores. When the ceramsite is used for cultivating or planting various seedlings, flowers, plants and vegetables, roots of the plants may absorb water or nutritional ingredients of liquid-state fertilizer from the ceramsite, so that sound growth and development and high survival rate of the plants are ensured. The ceramsite is suitable for being used to prepare soilless culture matrixes and nutritional soil.

Description

technical field [0001] The invention relates to ceramsite, in particular to a lightweight through-hole ceramsite of mixed layer clay of Illuminate. 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, m...

AI Technical Summary

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.
