The specific mechanism of aluminum paste in aerated concrete
Gas generation volume: The gas generation volume of aluminum paste determines its usage in aerated concrete. Gas generation volume refers to the volume of hydrogen produced by the full reaction of unit mass of aluminum powder under standard conditions. The more metallic aluminum content in aluminum powder, the greater the gas generation volume, and the greater the actual gas generation volume.
Fineness: The fineness of aluminum powder affects the gas generation speed. The finer the aluminum powder, the larger the specific surface area, the earlier the gas generation starts, the faster the speed, and the earlier the gas generation ends.
Particle shape: The shape of aluminum powder particles has an important influence on the gas generation characteristics. Droplet-shaped aluminum powder has low chemical activity and almost no gas generation; while broadleaf-shaped or irregular scaly aluminum powder has good gas generation effect.
Specific application effect of aluminum paste in aerated concrete
Aerated concrete blocks produced using aluminum paste have the characteristics of uniform pores, moderate pore diameter, and appropriate thickness of the interpore wall, and the compressive strength meets national standards. This porous structure makes aerated concrete perform well in thermal insulation, heat insulation and sound insulation, and is widely used in the construction field.
