AI Technical Summary

Technical Problem

In existing technologies, waste ceramic powder has a low activation energy, which leads to slow reaction with other substances, poor bonding, low strength of the prepared ceramic bricks, and failure to effectively utilize its resources, resulting in environmental pollution and resource waste.

Method used

By pulverizing waste ceramics through plasma treatment and coating them with SiO2 film, the activity and dispersibility of the waste ceramic powder are improved. Special hybrid fibers are introduced into the ceramic bricks to improve the bonding and strength. At the same time, the photocatalytic properties of the hybrid fibers are used to degrade pollutants.

Benefits of technology

It improves the mechanical properties and wear resistance of ceramic tiles, broadens the utilization of waste ceramic powder, realizes the comprehensive utilization of resources, reduces production costs, and endows ceramic tiles with self-cleaning properties.

Abstract

This invention discloses a waste porcelain powder, belonging to the field of building ceramics technology. It is obtained by coating the surface of activated and pulverized waste porcelain with a SiO2 film. The activated and pulverized waste porcelain is plasma-treated and pulverized. This invention also discloses the application of this waste porcelain powder in ceramic bricks, with the following steps: adding water to the raw material of the body and performing wet ball milling, spray drying, pressing and molding by molding, drying, to obtain a ceramic brick body; adding water to the raw material of the glaze and performing wet ball milling to obtain a glaze slurry, removing iron from the glaze slurry and sieving to obtain a ceramic brick glaze; spraying the ceramic brick glaze onto the surface of the ceramic brick body by spraying, drying, and firing in a kiln to obtain a ceramic brick; this invention uses waste porcelain powder as the main raw material to prepare a ceramic brick body, and adds specially made hybrid fibers to the raw material of the body, and then matches it with a ceramic brick glaze containing waste porcelain powder and hybrid fibers with specific components. The resulting ceramic brick has high strength, high wear resistance, and also has self-cleaning properties.
