Preparation and Current Analysis of DEG Aluminum Paste (Slurry/Powder)

Chapter 1: Overview of Aluminum Paste (Slurry)/Powder

1.1 Definition of aluminum paste (slurry)/powder for gas filling

Aluminum aerated paste (slurry)/powder is a specialized gas-generating additive used in the production of autoclaved aerated concrete (AAC, Autoclaved Aerated Concrete). Its main component is aluminum powder, supplemented with other additives. This material reacts with water to produce hydrogen gas, which forms numerous tiny bubbles within the concrete. This characteristic makes aluminum aerated paste (slurry)/powder play a crucial role in the building materials industry, especially under the increasingly stringent requirements for lightweight, high-strength, and thermal insulation properties in modern construction.

The chemical reaction of aerated aluminum paste (slurry)/powder can be vividly compared to bread fermentation. In bread making, baking powder reacts with water to produce carbon dioxide gas, causing the dough to expand and become soft; similarly, in the production of aerated concrete, aerated aluminum paste reacts with water to produce hydrogen gas, forming bubbles that reduce the density of the concrete, achieving a lightweight effect. This bubble structure not only reduces the weight of buildings but also significantly enhances their thermal insulation and soundproofing performance.

The performance of aerated aluminum paste (slurry)/powder is closely related to its composition, the characteristics of aluminum powder, and the ratio of additives. High-quality aluminum powder typically has a smaller particle size, good dispersibility, and high activity, allowing it to react more effectively with water, producing uniform and stable bubble structures. Conversely, low-quality aluminum powder can lead to uneven bubble formation, affecting the final performance of the concrete. Therefore, when selecting aerated aluminum paste (slurry)/powder, the choice of raw materials and control of production processes are crucial.

In addition to aluminum powder, other additives are often added to aerated aluminum paste (slurry) to enhance its reactivity and overall performance. For example, the introduction of compounds such as DEG (glycerol alcohol) not only increases the reaction rate of aluminum powder but also improves the workability and stability of the final product. The ratio and application methods of these additives have a profound impact on the quality and performance of the aluminum paste (slurry).

In summary, aerated aluminum paste (slurry)/powder is an indispensable part of modern building materials. In the context of the global construction industry’s growing pursuit of lightweight, efficient, and environmentally friendly products, the demand for aerated aluminum paste (slurry)/powder continues to rise. With the continuous development of related technologies, its production processes and application scope are also expanding, contributing to the advancement of the construction industry towards greener and more sustainable directions.

The main components of aluminum paste (paste)/powder include aluminum powder and a variety of additives, which together determine its performance and application effect. Before understanding these components, it is necessary to first recognize the key role of aluminum powder in the process of gas generation.

1. Aluminum powder

Aluminum powder is one of the core components of aerated aluminum paste (slurry)/powder, typically existing in flake or spherical form. Its particle size, thickness, and activity directly impact the quality of aerated concrete. When aluminum powder reacts with water, it releases hydrogen gas, forming bubbles that are locked during the hardening process of the concrete, thus creating aerated concrete blocks with excellent thermal insulation and lightweight properties. The selection of aluminum powder is crucial; high-quality aluminum powder should have a smaller particle size and good activity to ensure uniform distribution of bubbles.

2. Additives

In addition to aluminum powder, additives play a crucial role in aerated aluminum paste (slurry). Commonly used additives include DEG (glycerol), water, and other chemical additives. DEG can effectively increase the reaction rate of aluminum powder, enhancing its affinity with water, thus accelerating hydrogen production. Moreover, the use of additives can improve the flowability and stability of the aluminum paste, making it easier to handle and transport during production.

3. Other ingredients
