Bauxite lightweight through-hole ceramsite

Abstract

The invention discloses a bauxite lightweight through-hole ceramsite. The key point of the technical scheme is that the bauxite lightweight through-hole ceramsite consists of bauxite, attapulgite, a powdered bauxite foamer, activated clay waste residues, floating beads, light magnesium oxide, expanded perlite, expanded vermiculite and ferrous sulfate. The ingredients of the bauxite lightweight through-hole ceramsite are stirred and mixed, extruded and pelletized, dried, roasted, warm-kept, sieved and then packaged in a sealing manner. The bauxite lightweight through-hole ceramsite has the characteristics of large specific surface area, small stacking density, high water absorption, superior air permeability, attractive appearance modeling, no foreign smell, no harmful germ, light weight, high strength, and micropore and macropore integration. When the bauxite lightweight through-hole ceramsite is used for cultivating or planting various seedlings, flowers and plants and vegetables, the plant roots can absorb nutritional ingredients of water or liquid fertilizers from the bauxite lightweight through-hole ceramsite, so that good growth and development, high survival rate and longer service life of the plants are ensured, and the bauxite lightweight through-hole ceramsite is suitable for preparing soilless culture substrates and nutrient soil.

Description

technical field [0001] The invention relates to ceramsite, in particular to a bauxite 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 as fly ash c...

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.
