Cement foam insulation board is a new type of fireproof, heat preservation and energy saving inorganic material

Introduction to chemical foamed cement

Chemical foaming Cement uses a chemical method (chemical reaction) to generate gas to foam the cement material to form a porous material. This foaming form and process is called chemical foaming cement.

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 require mechanical means to directly generate a large number of bubbles through chemical reactions to achieve the purpose of foaming. Only need to mix the foaming agent and cement composite material with water thoroughly to react. The foaming process takes 5-15 minutes, and the cells after foam molding are generally honeycomb closed cells.

Classification of blowing agent

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-flammable, good thermal stability, no chemical reaction in the gaseous state, and the diffusion rate of the gaseous state in the plastic melt is lower than the diffusion rate in the air. Commonly used physical blowing agents include air, nitrogen, carbon dioxide, hydrocarbons, freon, etc.; chemical blowing agents are substances that release gases such as nitrogen and carbon dioxide when heated. The requirements for chemical foaming agents are: the gas released by decomposition should be non-toxic, non-corrosive, non-flammable, and have no effect on the molding and physical and chemical properties of the product. The gas release rate should be controlled, and the blowing 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 foam 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 main raw materials. Added chemical foaming agent, multifunctional additives, special fiber and other materials. , A new type of thermal insulation board made of chemical foaming and pouring. The board has the advantages of good thermal insulation performance, light weight and shock resistance, good relative strength, not fragile, good water resistance, non-toxic and harmless, environmentally friendly and energy-saving, and has the same service life as buildings. It belongs to Class A non-combustible thermal insulation material.

Overview of chemical foamed cement

Synthetic foaming agent for concrete is a high-concentration, high-efficiency liquid used in the production of lightweight foam concrete, which is also called cellular lightweight concrete (CLC).

CLC concrete has very good potential in helping to build cellular lightweight applications. Using the correct type of foaming agent can make a huge difference in product properties (such as the mechanical properties of concrete and its resistance, etc.). Synthetic foaming agents are chemical substances that reduce the surface tension of liquids and are widely used in the manufacture of blocks, bricks, CLC concrete, etc. worldwide. Compared with other foaming agents, when high density is required, less energy is required for formation. Highly recommended for the construction industry, the demand for lightweight concrete has increased over time.

Chemical foamed cement application

1. Foaming agent is used to make lightweight (clc) blocks and panels;

2. The foaming agent is used to fill in the blanks;

Foamed concrete is also very useful for void filling. Because of its high mobility, it can dump even in the most inaccessible places. It can be used for planning work, and it can also provide stability and support very quickly in an emergency;

3. Foaming agent is used for roof insulation;

4. Foaming agent is used to mark CLC blocks, cast-in-place walls, bridge reinforcement wall construction, floor slab construction, lightweight prefabricated blocks, fire protection, sound insulation, etc.
