Method for processing and manufacturing light brick by utilizing household garbage

Abstract

The invention relates to the technical field of light brick processing and in particular relates to a method for processing and manufacturing a light brick by utilizing household garbage. Low-grade diatomite is doped with high-calcium coal gangue, household garbage and other wastes, and ultramicropore light-weight high-strength sintered insulating brick is produced. Compared with the processing of common clay sintered brick and aerated concrete insulating brick, the requirements of compressive strength are met, the production cost is reduced, and the light brick has excellent light insulating performance. All raw materials come from household and industrial wastes, the treatment problems of household garbage and industrial slag removal are solved, the environmental pollution problem caused by solid wastes is solved, the cultivated land resources are protected, the solid wastes are recycled, and the building energy conservation requirements are met.

Description

technical field [0001] The invention relates to the technical field of light brick processing, in particular to a method for making light bricks by using domestic garbage. Background technique [0002] In recent years, there are many high-rise buildings. In order to reduce the weight of the buildings, various light wall materials are used in large quantities, so various light bricks emerge as the times require. But the most popular ones are energy-saving sintered bricks with low density, high strength, thermal insulation, sound insulation, heat insulation, and good seismic performance. This is also the focus and direction of the development of national wall materials. [0003] Diatomaceous earth is a kind of biogenic siliceous sedimentary rock, mainly composed of diatom remains and silicate minerals. The chemical composition is: SiO2, AL2O3, Fe2O3, CaO and organic matter, etc. The loss on ignition is 7% to 10%. my country is rich in diatomite resources, with proven reserves...

AI Technical Summary

Problems solved by technology

[0004] The current diatomite bricks are difficult to open the market because of high production cost, high production difficulty, high product rejection rate, low compressive strength, large consumption of diatomite raw materials and low utilization rate of solid waste. It is relatively high and lacks market competitiveness. Currently, it is only used as an environmental protection material for industrial kilns and high-end residential buildings, which greatly limits the application field and promotion of this product.
