AI Technical Summary

Technical Problem

Existing technologies for mineral-based solid waste slurries suffer from problems such as insufficient filler fluidity, severe sedimentation and segregation, poor uniformity, and poor long-term durability. These issues lead to substandard strength in engineering applications, increased overall engineering costs, and the resulting solidified materials are prone to cracking and pulverization in natural environments, thus shortening the service life of engineering projects.

Method used

A multi-stage grinding and graded screening closed-loop linkage process is adopted, combined with Zeta potential regulation and ultrasonic homogenization treatment. By precisely controlling the Zeta potential of solid waste slurry, potassium hexapolymetaphosphate or sodium pyrophosphate is used as a potential regulator to prepare a stable solid waste-based homogeneous slurry, which is then mixed with a composite solidifying agent to form a high-strength, highly uniform solidified soil.

Benefits of technology

It achieves uniformity and stability of slurry systems with high and low calcium content, improves the compressive strength and long-term storage performance of solidified soil, is suitable for various engineering scenarios, reduces production costs and energy consumption, and is suitable for large-scale production.

Abstract

This invention relates to the field of mineral-based solid waste resource recycling, specifically to a solid waste-based homogeneous slurry and its preparation method. Using mineral-based solid waste as the core raw material, supplemented with water, grinding aids, and potential regulators, a stable solid waste-based homogeneous slurry is prepared through a complete process including raw material pretreatment, coarse grinding, fine grinding, graded closed-loop screening, precise Zeta potential control, and ultrasonic homogenization. This slurry can be used with composite solidifying agents to prepare solidified soil for engineering applications. This invention establishes a precise matching mechanism between the calcium content of solid waste and the potential regulator. Potassium hexapolymetaphosphate is preferred for high-calcium mineral-based solid waste, while sodium pyrophosphate is preferred for low-calcium mineral-based solid waste. It is suitable for all types of high-calcium and low-calcium bulk mineral-based solid waste. The prepared slurry exhibits excellent homogeneity and can be stored for a long time. The solidified products have high mechanical strength and low performance dispersion. The preparation process parameters are controllable and suitable for large-scale continuous production, showing broad application prospects.
