Cement foaming agent-protein cement foaming agent

The foaming principle of protein foaming agent is the degradation of the protein. The cleavage of peptide bonds in protein macromolecules will produce soluble protein-small molecules. With the increase of protein-small molecules in the solution, hydrophobic groups gradually increase, which reduces the surface tension and forms an interface.In addition, due to the formation of hydrogen bonds between special groups in the molecule, strong hydrogen bonds can ensure the formation of high-strength foam liquid film in the solution so that the foaming agents can generate stable foam. Protein foaming agents can be generally divided into animal protein foaming agents and vegetable protein foaming agents. China's protein foaming agents were mostly imported from Italy, the United States, Japan, South Korea, and other developed countries, and more and more domestic products have been produced in recent years. But generally speaking, the quality of imported products is still higher than that of domestic products. The performance of domestic protein foaming agents should fully reach the level of imports, and efforts should be made to further improve and improve the technology. Surfactant compound cement foaming agent: The protein and surfactant compound foaming agent can further enhance its surface activity by changing the interfacial tension of the solution, and the interfacial adsorption mechanism in the mixed system is mainly replacement and solubilization. By studying the foaming effect of protein-surfactant composite foaming agent, it was found that the situation at the interface of protein and surfactant could affect the stability of the foam. The more active agent molecules adsorbed on the membrane, the stronger the elasticity and the higher the density, so the gas in the foam is not easy to diffuse to the outside through the liquid membrane and the foam can exist stably for a long time.
