Chemically foamed cement Chemically foamed The use of chemical reactions to produce gas in cement materials is known as cement. Chemically foamed concrete is the name of this foaming form.
Chemical foamed concrete insulation board
Chemical foamed concrete is a method for releasing gas by causing the cement to react chemically with its own material. Its unique feature is the fact that it does foam without mechanical means. Chemical reactions directly create a lot of bubbles. To react, it is only necessary to mix the foaming material and cement composite with water. The foaming process can take between 5 and 15 mins, with the cells that form after foam molding being honeycomb cells.

Foaming agent classification
Foaming agents Chemical foaming and physical foaming are roughly divided. The physical foaming agent must meet the following requirements: it should be non-toxic and non-combustible. It also needs to have good thermal properties, not cause a chemical reaction when in gaseous form, and its diffusion rate is lower in gaseous form than in air. Air, nitrogen, carbon dioxide, hydrocarbons and freons are all common physical blowing agent. Chemical blowing agent substances can release gases, such as carbon dioxide and nitrogen when heated. The decomposition gas must be nontoxic, noncorrosive, and noncombustible. The gas should not have any effect on the molding, physical, or chemical properties, of the product. The gas release rate should be controlled and the foaming agents should be well dispersed 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.

Insulation Board
Cement foamed insulation board is the latest inorganic thermal insulation material. It’s also fireproof and energy saving. It is made primarily of inorganic phase-change materials and silicates as its main raw material. Additions include multifunctional additives (multifunctional foaming agents), special fibers and materials. This is a new type of thermal board that has been formed through chemical foaming. The board offers good thermal insulation, is lightweight and shock-resistant, has a good relative strength, is not fragile, is resistant to water, and it’s non-toxic.
