Description

Technical Field

[0002] The composite wall panel is a new generation of high-performance interior partition for buildings produced industrially, which is composed of a variety of building materials and replaces traditional bricks and tiles. It has the obvious advantages of environmental protection, energy conservation, no pollution, light weight, earthquake resistance, fire prevention, heat preservation, sound insulation, and fast construction. The composite wall panel uses ordinary Portland cement, sand, fly ash or other industrial wastes such as water slag and slag as fine aggregates, and then adds polystyrene particles and a small amount of inorganic chemical additives. With a fully automatic and highly efficient forced lightweight aggregate special mixing system, air is introduced during the mixing process to form honeycomb-shaped stable pores in the core layer to further reduce the bulk density of the product, which not only reduces the material cost but also achieves an ideal heat preservation and sound insulation effect.
