Flint clay light porous ceramsite

Abstract

The invention discloses a flint clay light porous ceramsite. The key points of the technical scheme are as follows: the flint clay light porous ceramsite is composed of flint clay, attapulgite clay, a powdery flint clay foaming agent, activated clay waste residues, floating beads, light magnesium oxide, expanded perlite, expanded vermiculite, ferrous sulfate and calcined lime. The ingredients of the flint clay light porous ceramsite are subjected to stirring and mixing, extruding granulation, drying, roasting, thermal insulation, screening and sealing and then packaging to obtain the flint clay light porous ceramsite. The flint clay light porous ceramsite has the characteristics of large specific area, small bulk density, high water absorption rate, excellent air permeability, beautiful appearance, no odor, no harmful germ, excellent light strength and integrated micropore and macropore. When the flint clay light porous ceramsite is used for planting or cultivating various nursery stocks, flowers and plants and vegetables, the roots of the plants can absorb water or nutritional ingredients of liquid fertilizer through the flint clay light porous ceramsite, so that excellent growth and development and high survival rates of the plants can be ensured; and the flint clay light porous ceramsite is suitable for preparing soilless culture substrates and nutrient soil.

Description

technical field [0001] The invention relates to ceramsite, in particular to a light through-hole ceramsite of burnt gemstone. 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 a...

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.
