Problems solved by technology

[0004] At present, my country's treatment of ceramic waste and marble waste is mainly through simple landfill methods. Ceramic waste belongs to dust waste. If it is directly buried without treatment, it will cause serious air pollution and produce haze weather. , causing secondary pollution, affecting people's health and causing harm to the environment

Abstract

The invention relates to a dry powder plastering mortar made from ceramic waste residues and a manufacturing method thereof. The manufacturing method is characterized in that ceramic waste residues, fly ash, marble waste residues, silicate cement, calcium oxide, calcium sulfate, expanded polystyrene, starch ether, alkylbenzene sulfonate air entraining agent, methyl cellulose ether, polycarboxylate high-efficiency water reducing agent and vinyl acetate-ethylene copolymer gelatine powder, which are used as raw materials, are evenly mixed by a mixer to make the dry powder plastering mortar product. The raw materials in the invention can also be made into different types of thermal-insulation mortar and waterproof mortar. The product has the advantages and effects of light weight, high strength, no pollution, low cost and favorable benefit.

Description

technical field [0001] The present invention relates to a kind of dry powder plastering mortar produced by ceramic waste slag, specifically, it is mainly the powder material after crushing, sorting, pulverizing, drying and wheel milling and sorting of ceramic waste slag and marble waste slag. The dry powder plastering mortar produced from raw materials belongs to the field of waste treatment. [0002] The invention also relates to a manufacturing method of the dry powder plastering mortar. Background technique [0003] Ceramic waste slag is waste porcelain mud and damaged blanks produced by ceramic factories in the process of producing porcelain, damaged waste products that have not been calcined and glazed, semi-finished products that have been calcined and glazed in the factory, waste products due to damage or cracks, and waste products from construction Waste building ceramics, waste sanitary ceramics and other places where ceramics are applied on the construction site, ...
