Problems solved by technology

[0003] The existing ceramsite uses sludge as the main raw material, and kaolin, fly ash, etc. as auxiliary materials. Under certain technological conditions, the decarburization and burning 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. Due to the complex chemical composition and microstructure of the raw materials, the strength of the existing ceramsite needs to be improved

Abstract

The invention belongs to the technical field of ceramsite, and particularly relates to a curing agent for enhancing the intensity of ceramsite and a preparation method of the curing agent. The curing agent comprises the following raw materials in parts by weight: 10-30 parts of bauxite, 5-9 parts of starch xanthate, 1-3 parts of graphene oxide, 5-9 parts of bentonite, 1-3 parts of chitosan-graphene composites, 10-12 parts of dextrin, 10-15 parts of glycerin monostearate, 5-9 parts of magnesium oxide and 20-35 parts of flyash. The curing agent is used for modifying ceramsite raw materials, so that the raw materials achieve the purpose of mutual compatibility, form the homogeneous state of dispersion system and change the previous physical state. The organic and inorganic pollutants in the raw materials can be cured and stabilized, and the optimized raw material compounding can effectively improve the quality of the intensity of ceramsite so as to achieve the purpose of improving the intensity of ceramsite.

Description

technical field [0001] The invention relates to the technical field of curing agents, in particular to a curing agent for enhancing the strength of ceramsite 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 tre...
