What is a concrete foaming agent? Concrete foaming agent, also known as foam concrete foaming agent, concrete foaming agent refers to can reduce the surface tension of the liquid and produce a large number of uniform and stable foams used to produce foamed concrete admixture. The foaming agent is a kind of substance that can make its aqueous solution produce a large amount of foam under the condition that mechanical force is introduced into the air. This kind of substance is a surfactant or surface-active substance. The essence of the foaming agent is its surface active action. Without surface activity, it can not foam and also can not become a foaming agent; surface activity is the core of foaming.
Application of concrete foaming agent Concrete foaming agents belong to one category of narrow foaming agents, but not all of them. The narrow blowing agent, which can be used in foam concrete, is only a very small part, is very little. This is determined by the characteristics and technical requirements of foamed concrete. In industrial production and daily civil use, the use of foaming agents is very different; different application fields have different technical requirements for a foaming agent. For example, a fire extinguisher foaming agent only requires its instantaneous foaming volume and the barrier ability of oxygen but does not require its higher stability and delicacy. Another example is the flotation foaming agent used in mining, which only requires that it has a strong adsorption force and good foaming force for the object and does not require high foaming multiple and foam stability. And so on and so forth. The foaming agent is used in almost every industrial field and has a wide range of uses. The performance requirements of a foaming agent are obviously different in various industries. The foaming agent used in one industry can not be used, or the effect is not good in another industry. Similarly, foam concrete foaming agent is for concrete foaming to put forward the technical requirements. In addition to the ability of large foam generation, it pays special attention to the stability of foam, the delicate nature of foam, and the adaptability of foam and concrete and other cementing materials. Can meet the requirements of the narrow blowing agent are also very few, and most foaming agents can not be used in the actual production of foam concrete. Therefore, the foaming agent of foamed concrete must be a small number of surfactants or surface-active substances that meet the above technical requirements.
Method of use of concrete foaming agent 1. Because the concentration of concrete foaming agents is generally large, the direct addition of a foaming machine will lead to low foam production and waste foaming agent. Direct-add foaming machines will generally be high concentration and can not produce high-quality foam. At the same time easy to block the concrete foam machine into the pump. Concrete foaming agent dilution and foaming effect are very important. So you can't have a dilution that's too high or too low, so you have to have a very good dilution. In determining the reasonable dilution ratio of the concrete foaming agent, on the one hand, we should refer to the dilution ratio suggested by the manufacturer; on the other hand, we need to do the test directly in our foaming machine to determine the appropriate dilution ratio of foaming agent. 2. After determining the combined ratio, it is necessary to dilute it into foaming liquid with water and then make foam products from the foaming liquid. Pour the water and foaming agent into a water cylinder to fully dissolve, observe the blisters, put the prepared concrete into the cylinder, and then use the mixing tools to fully stir through the high-pressure conveying pipe or manually into the wall machinery for processing into finished products.
