| Current use of cement foaming agent is mainly divided into three types: |
1.Rosin soap foamer
You loose soap foam is used earlier a foaming agent, is made of rosin and sodium hydroxide as the main raw material after saponification reaction take, as its main component of rosin resin, sodium salt, appears light brown liquid. It has the advantages of simple manufacturing process, low material cost, but its foaming ability and foam strength is poor, has gradually been eliminated, only a few manufacturers are still producing. |
2.Animal foaming agent
Animal foaming agent is to animals ( cattle, sheep ) horny protein as the main raw material, adding certain amount of sodium hydroxide, hydrochloric acid, magnesium chloride and other chemical raw materials, heating solution, diluted, filtered, heat shrink and become, dark brown viscous liquid, also known as protein foaming agent. Quality of the animal with a foam blowing agent, the foam large amount of high intensity, long duration and other advantages, the current domestic manufacturers of foaming agent for the products. |
3 plant a foaming agent
Botanical foaming agent is a natural polymer materials as raw materials, through a series of complex chemical reaction. This foaming agent to light yellow transparent liquid, soluble in water, the water is not sensitive, non-toxic, tasteless, has excellent foaming capacity, foam rich, dense, South Korea warm construction used in the blowing agent 80% for this kind of product.

Two, cement foaming agent characteristics
|
 
Different foaming agents with different packaging
|
We research the strong cement foaming agent based on polymer materials as the main raw material, adding a certain amount of chemical raw materials, heating solution, diluted, filtered, temperature dehydration, and the production of cement additives, has a low absorption rate, density balance, maintain the strength of the advantages of a long time, is a pollution-free, pollution is harmful to a human body and water soluble liquid, is environment-friendly strong foaming agent。

After the foaming of foamed concrete, also called foaming concrete, is made up of water, cement and foaming agent by mixing with the machine, after the solidification, the bulk density of 380 ~ 1600kg / m3, 30 ~ 50kg / cm2 can withstand the pressure, is insulation, impermeability ( plus a procedure can be waterproof, thermal insulation, sound insulation ), light quality, environment-friendly foaming concrete.
| Three, the scope of application |
1)Floor radiant heating thermal insulation layer and the roof insulation;
2)Both inside and outside the building block filled wall, sound insulation walls;
3)Municipal pipelines such as water supply, heating, pipelines and other insulation, moisture-proof, anti-corrosion;
4)Plants cultivated in greenhouse and storage of cold storage building;
5)Internal voids and cracks filled tunnel building;
6)The sidewalk, sports grounds, golf course grass laying; |
| Four, storage |
|
Foaming agent should be sealed and stored in special warehouse or a fixed place for safekeeping, to easily identify and facilitate inspection. Should be placed after the remaining solution sealed preservation, not mixed with foreign body. This product is not flammable, explosive goods. The product shelf-life of 2 years, when the product quality problems arise during the shelf and metamorphism, should be timely contact with suppliers。 |
