A kind of ceramsite curing agent and preparation method thereof

Abstract

The invention belongs to the technical field of ceramsite, and in particular relates to a ceramsite curing agent and a preparation method thereof. The ceramsite curing agent comprises the following raw materials in parts by weight: 5-9 parts of starch xanthate, 1-3 parts of graphene oxide 5-9 parts of bentonite, 1-3 parts of chitosan-graphene composite material, 10-12 parts of dextrin, 10-15 parts of glyceryl monostearate, 5-9 parts of magnesium oxide, 20 parts of fly ash ~35 parts; the ceramsite curing agent of the present invention is used to modify the ceramsite raw materials, so that each raw material can achieve the purpose of mutual compatibility, form a homogeneous dispersion system, change the previous physical state, and can solidify and stabilize the raw materials organic and inorganic pollutants to achieve the purpose of pollution control.

Description

technical field [0001] The invention relates to the technical field of curing agents, in particular to a ceramsite curing agent and a preparation method thereof. Background technique [0002] Ceramsite is a ceramsite particle, most of its appearance features are round or oval spheres, but there are also some gravel-like ceramsites that are not round or oval spheres, but irregular gravel. The shape of ceramsite varies from process to process. Ceramsite can solve engineering problems such as quality, fire prevention, heat insulation, and heat preservation, and can also be used for horticultural and hydroponic planting. [0003] The existing ceramsite uses sludge as the main raw material, kaolin, fly ash, etc. as auxiliary materials. Under certain process conditions, the decarburization and swelling of sludge are controlled, and sludge is often taken from urban domestic sewage. , printing and dyeing sewage, electroplating wastewater and other treated sludge contain a large am...

AI Technical Summary

Problems solved by technology

[0003] The existing ceramsite uses sludge as the main raw material, kaolin, fly ash, etc. as auxiliary materials. Under certain process conditions, the decarburization and swelling of sludge are controlled, and sludge is often taken from urban domestic sewage. , printing and dyeing sewage, electroplating wastewater and other treated sludge contain a large amount of organic pollutants and inorganic pollutants, and it is very difficult to eliminate organic pollutants and inorganic pollutants in sludge, especially for heavy metal pollutants. Therefore, sludge The produced ceramsite still has certain pollution and toxicity, which poses great safety hazards to society and the environment, and is not conducive to the sustainable development of society and the environment.
