Concrete block use aluminum pulver

 Characteristics of aerated aluminum paste   Aerated aluminum paste, also known as aerated material or foamed aluminum, is a new type of powder material prepared using powder metallurgy technology. Its main production characteristics include the following aspects.1. High specific surface areaThe particles of aerated aluminum paste are small and the specific surface area is large, so it has good activity and reactivity. Its specific surface area is usually between 10-50m2/g, while the specific surface area of ​​traditional aluminum powder is only 1-5m2/g. High specific surface area is one of the key characteristics of aerated aluminum paste to form air foam.2. Easy to foamBecause the particles of aerated aluminum paste are small and the specific   surface area is large, it has excellent activity and reactivity. It can react with water to generate hydrogen, and then undergo a violent foaming reaction. The bubbles produced by foaming have low surface tension, uniform pressu…
