Chemically foamed cement
The use of chemical reactions to produce gas in cement materials is known as cement. This chemically foamed form and process is called chemically foamed concrete.
Chemical foamed concrete insulation board
Chemical foamed concrete is the result of causing a chemical reaction with the material to release gas. It is notable for the fact that chemical reactions directly create a large number bubbles to achieve foaming. 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
Chemical foaming and physical foaming are roughly divided. Physical foaming agent requirements include: being non-toxic and odorless; non-corrosive and non-combustible; having good thermal stability. 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. Chemical blowing agent requirements include: the gas released during decomposition must be nontoxic, noncorrosive, and noncombustible. The gas should not have any effect on the physical and chemical properties or the molding of the product. The gas release rate should be controlled and the foaming agents should have good dispersion within 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 insulation board is the latest inorganic thermal insulation that’s fireproof and energy efficient. The board is made primarily of phase change materials and silicates as its main raw material. Additions include multifunctional additives (multifunctional foaming agents), special fibers, and other material. 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, has a good water-resistance, it’s non-toxic, harmless and environmentally friendly, and can last the same time as the building.
