Gas generation volume: The gas generation volume of aluminum powder determines its usage in aerated concrete. The greater the gas generation volume, the greater the volume of hydrogen produced by the full reaction of unit mass of aluminum powder under standard conditions. Therefore, the aluminum powder paste with a higher metallic aluminum content will also have a greater gas generation volume.
Fineness: The fineness of aluminum powder affects the gas generation speed. The finer the fineness, the larger the specific surface area, the earlier the gas generation starts and the faster the speed, but the larger fluctuation of fineness will affect the casting stability.
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 flaky aluminum powder has high chemical activity and good gas generation effect.
Purity and active aluminum content: Aluminum powder paste with higher purity (metal aluminum content not less than 98%, active aluminum content not less than 89%) performs better in aerated concrete.
Different types of aerated bricks and their application scenarios:
N series aerated bricks: Suitable for decorative partition walls, with good structural strength and light weight, suitable for occasions requiring a certain load-bearing capacity and indoor environmental comfort.
A5.0B07, A3.5B07, A5.0B06 and other models: The main difference between these types of aerated bricks is strength and porosity. Bricks with higher strength and lower porosity have better quality, but actual tests are needed to judge in actual use.
Specific steps and suggestions for selecting aerated brick aluminum powder paste models:
Choose according to actual needs: Consider factors such as wall load-bearing, thickness, environmental conditions and budget cost. It is recommended to use models with moderate bulk density and appropriate structural strength, such as N series aerated bricks. Testing and evaluation: The actual use can determine the strength. High-precision bricks are cut accurately with less error, while ordinary bricks may cause construction difficulties.
Pay attention to the reputation of the manufacturer: Choose a reputable manufacturer to ensure product quality and after-sales service.
