Foaming agent classification

Overview of foaming agent

Foaming agents can be roughly divided into physical foaming agents and chemical foaming agents. The requirements for physical blowing agents are: non-toxic, odorless, non-corrosive, non-flammable, good thermal stability, no chemical reaction in the gaseous state, and the diffusion speed in the plastic melt in the gaseous state is lower than that in the air Rate. Commonly used physical blowing agents include air, nitrogen, carbon dioxide, hydrocarbons, freon, etc.; chemical blowing agents are substances that release gases such as nitrogen and carbon dioxide when heated. The requirements for chemical foaming agents are: the gas released by decomposition should be non-toxic, non-corrosive, non-flammable, and have no effect on the molding and physical and chemical properties of the product. The gas release rate should be controlled, and the blowing agent should have good dispersibility in the plastic. Inorganic foaming agents such as sodium bicarbonate and ammonium carbonate and organic foaming agents such as azoformamide and azobisisobutyronitrile are widely used.

Introduction to chemical foamed cement

Chemical foaming Cement uses a chemical method (chemical reaction) to generate gas to foam the cement material to form a porous material. This foaming form and process is called chemical foaming cement.

Foaming agent application

What are the uses of synthetic foaming agents in concrete?

1. Foaming agent is used to make lightweight (clc) blocks and panels;

2. The foaming agent is used to fill in the blanks;

Foamed concrete is also very useful for void filling. Because of its high mobility, it can dump even in the most inaccessible places. It can be used for planning work, and it can also provide stability and support very quickly in an emergency;

3. Foaming agent is used for roof insulation;

4. Foaming agent is used to mark CLC blocks, cast-in-place walls, bridge reinforcement wall construction, floor slab construction, lightweight prefabricated blocks, fire protection, sound insulation, etc.
