Introduction of chemically foamed cement

Chemically foamed

cement is the use of chemical methods (chemical reactions) to generate gas to foam cement materials to form cellular porous materials. This foaming form and process are called chemically foamed cement.

Chemical foamed cement insulation board

The method of making it chemically react with the material itself to release gas is called chemical foamed cement. Its outstanding feature is that it does not need to resort to mechanical means, and directly generates a large number of bubbles through chemical reactions to achieve the purpose of foaming. It only needs to fully mix the foaming agent and the cement composite material with water to react. The foaming process takes 5 to 15 minutes, and the foam cells after foam molding are generally honeycomb closed cells.

Foaming agent classification

Foaming agents

can be roughly divided into physical foaming agents and chemical foaming agents. The requirements for physical foaming agents are: non-toxic, odorless, non-corrosive, non-combustible, good thermal stability, no chemical reaction in the gaseous state, and the diffusion rate in the plastic melt in the gaseous state are lower than that in the air Diffusion rate. Commonly used physical blowing agents include air, nitrogen, carbon dioxide, hydrocarbons, freons, etc. ; chemical blowing agents are substances that can release gases such as nitrogen and carbon dioxide when heated. The requirements for chemical blowing agents are: The gas released by decomposition should be non-toxic, non-corrosive, non-combustible, and has no effect on the molding and physical and chemical properties of the product. The rate of gas release should be controlled, and the foaming 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.

New insulation board

Cement foamed thermal insulation board is a new type of fireproof thermal insulation and energy-saving inorganic material. It is mainly made of silicate and inorganic phase change materials as the main raw materials. It is added with chemical foaming agents, multifunctional additives, special fibers and other materials. , A new type of thermal insulation board formed by chemical foaming and pouring. The board has the advantages of good thermal insulation performance, lightweight and shock resistance, good relative strength, not fragile, good water resistance, non-toxic and harmless, environmentally friendly and energy-saving, and has the same life span as the building, and belongs to the Class A non-combustible thermal insulation material.
