The so-called foaming agent is the substance that makes the target substance pore-forming, which can be divided into three categories: chemical foaming agent, physical foaming agent and surfactant. Chemical foaming agents are those compounds that can release gases such as carbon dioxide and nitrogen after heating and decomposition, and form pores in polymer compositions;
Physical foaming agent is that the pores of foam are formed by the change of physical form of a substance, that is, the expansion of compressed gas, the volatilization of liquid or the dissolution of solid; Foaming agent has high surface activity, which can effectively reduce the surface tension of liquid. Double electron layers are arranged on the surface of liquid film to surround air, forming bubbles, and then a single bubble forms foam.
Extended data:
Plant cement foaming agent is made of imported high-quality natural plant polymer materials through a series of complex chemical reactions. The product is light yellow, pure and transparent oily liquid.
Not sensitive to hard water, non-toxic, tasteless, no sediment. The PH value is close to neutral, which is non-corrosive to cement and metal and does not pollute the environment. The foaming agent is resistant to storage, difficult to deteriorate, excellent in foaming performance, rich in foam and moderate in foam stability. Foamed cement made of this foaming agent has the characteristics of low consumption, low cost and stable quality. A barrel of foaming agent (200kg) can produce about 500 cubic meters of foamed cement, so it is widely used in floor heating engineering and roof insulation engineering, which can significantly reduce the construction cost.
