1. Animal protein foaming agent

Animal protein foaming agent is produced from the horns of animals (cattle, sheep, horses, donkeys, etc.) horn horns as raw materials, through a series of hydrolysis chemical reactions, and physical treatment such as filtration and purification, and other chemical raw materials are added at the same time. It is an admixture for concrete lightweight building materials. The generated foam has strong stability, and most of the generated foam remains after 24h.

Principle

The bubble liquid film formed by animal keratin is very tough and elastic. After being pressed by external force, it can be restored to its original state immediately and is not easy to break. Therefore, the pores of the foamed concrete produced are mostly closed spherical with few connected pores. Foaming agent features Stable foam and small diameter, suitable for producing ultra-low density foamed concrete.

Advantages and Applications

The foamed concrete has good pouring stability and high strength of the foamed concrete, which is a new type of environmentally friendly and efficient cement foaming agent.

This product does not contain substances harmful to the human body and is an environmentally friendly product.

The foamed concrete obtained by adding foaming agent to cement is a new type of building material. It has a series of characteristics such as excellent thermal insulation and sound insulation, and is currently a building material that meets the domestic energy-saving standards for housing construction.

Widely used in floor heating construction and internal and external wall insulation.

2. Microbial foaming agent

Yeast uses its own biochemical reaction to decompose nutrients and generate functional groups with hydrophilic or hydrophobic properties, thereby reducing the surface tension of the foaming agent solution, and introducing air under the action of external force to generate foam.

The yeast contains a large amount of protein, so the stability of the foam is good.

Advantage

Microbial foaming agent has better stability and cost performance.
