Industrial waste residue becomes environmental protection permeable brick.

Do you know that those seemingly useless industrial waste residues and wastes actually have great potential? Using the sintering method skillfully, these wastes can be transformed into environmentally-friendly bricks with excellent water permeability. This paper will discuss this magical transformation process in depth to help readers better understand the production principle of environmental protection bricks.

Raw material formula

We use 50-70% waste porcelain powder and mix it with basic materials such as porcelain stone, ankou soil, Shangdian soil and talc. , formed by dry pressing method, and then fired at1100-1150℃. This raw material formula can ensure the quality and performance of bricks.

Sintering method

Sintering is a key step in manufacturing environmentally friendly bricks. At high temperature, various components in raw materials will react chemically to form new crystal structure and phase composition. This ensures the performance and quality of the brick.

key factor

Factors such as the amount of waste residue and particle gradation, the particle size and proportion of base material, molding pressure and firing system will affect the water permeability of brick. In order to ensure the strength of brick, we have taken some special technological measures, such as introducing glass powder, reducing the amount of waste residue, optimizing particle gradation, increasing molding pressure and increasing firing temperature.

water permeability

Finally, the proportion of each phase in the water-permeable brick we obtained is just right: glass phase 20-30%, crystal phase 30-40% and pore phase 30-40%. This ratio ensures that the water permeability and strength of the brick reach the best state.
