What is Cement foaming agent?
Cement-foaming agents belong to a category of narrow-blowing agents, but not all. In the narrow blowing agent, only a tiny part can be used for foam concrete, which is very few. The characteristics and technical requirements of foam concrete determine this. In industrial production and daily civil use, the use of blowing agents varies greatly, and different application fields have different technical requirements for blowing agents. For example, the blowing agent used in a fire extinguisher only requires its instantaneous foaming amount and its blocking ability to oxygen but does not require high stability and fineness. Another example is the flotation foaming agent used in mining, which only requires a strong adsorption force for the object and an excellent foaming force, and the foaming ratio and foam stability are not high requirements. And so on, only to list some of them. The blowing agent is widely used in almost every industrial field. The performance requirements of foaming agents in various industries are different, and the foaming agent used in one industry can not be used, or the effect could be better in another industry. Similarly, the foaming agent used in foam concrete puts forward technical requirements for concrete foaming. In addition to the ability to generate large foam, it pays special attention to the stability of foam, fineness, and the adaptability of foam and cement materials. The narrow blowing agent that can meet this requirement is also manifold and few and most of the blowing agents can not be used to produce foam concrete. Therefore, foam concrete foaming agents must be a small number of surfactants or surface-active substances that meet the above technical requirements. It is precisely because of the ambiguity of the concept that many people fall into a big misunderstanding in practical application, confusing the two different concepts of "blowing agent" and "foam concrete blowing agent." all blowing agents are bought and used. The result is no foaming effect, and the foam concrete can not be produced per the requirements. Therefore, we need to clarify these concepts and their differences, which can avoid misunderstandings in blowing agents and take many detours. We should understand that many things called "blowing agents" on the market are not foam concrete blowing agents.
Selection method of cement blowing agent
Different types of foaming agents have different forces, and foam stability is different, so there are certain limitations in the use process. For example, the foam stability and foaming multiple of rosin blowing agents are not very good, so it can only be used for foamed magnesite cement with a bulk weight greater than 600㎏/m³, but not for low-density foamed magnesite cement below 500㎏/m³; Anionic synthetic surfactants foaming agents foaming fast, a large amount of foam, but the foam stability is poor, low density (500㎏/m or less) foam magnesite products are challenging to produce; The foaming power and foam stability of protein foaming agents are relatively good, but the foam viscosity emitted is large, which is not conducive to mechanized production. Composite foaming agents have better foaming power and foam stability, but the specific technical indicators of foaming agents are also different. Only after understanding the blowing agent type can the performance characteristics be understood, and the choice of blowing agent can be used. The main indexes to measure the quality of foaming agents are foaming power, foam tenacity, water secretion, etc. The foaming force reflects the foaming ability of the foaming liquid, which can be expressed by foaming height and foaming multiple. The higher the foaming height and the larger the foaming multiple, the stronger the foaming force of the foaming agent. Foam toughness is the characteristics of foam in the air in a specified time not to destroy, often expressed by the semi-extinction time and the subsidence distance of the foam column in a unit of time, the longer the semi-extinction time and the smaller the subsidence distance per unit time, the better the toughness of the foam.
Production of cement blowing agent
The application of cement-blowing agents in China has a history of more than 50 years. In the early 1950s, China developed two foaming agents, rosin soap and rosin hot polymer, and used them in mortar and Cement foaming agents. These two blowing agents have been widely used in China for decades. They are familiar with the building materials construction industry, the first generation of blowing agents in China and still have a more significant application. After the 1980s, with the rise of China's surfactant industry, synthetic surfactant foaming agents began to be applied. They replaced a considerable part of rosin soap and hot polymers, becoming various foaming agents. This is the development period of the second-generation blowing agent in China. At the end of the last century, high-performance protein-blowing agents from developed countries such as Italy, Japan, South Korea and the United States began to enter China with the opening up of the Chinese market. It gradually showed its advantages of high stability and got more significant applications. With the promotion of foreign protein-blowing agents, various brands of animal protein-blowing agents have also been developed in Qinghai and other places in China, and plant protein-blowing agents have also begun to appear and promote their application in southeast coastal areas. China has entered the development and application period of the third-generation blowing agents. Nowadays, China's blowing agent is transitioning from the third generation to the fourth generation, and the blowing agent is gradually developing from a single component to a multi-component compound. However, this is only the beginning; composite technology still needs improvement, and China will take time to enter the composite blowing agent era fully. Therefore, China is the first generation of rosin, the second generation of synthesis, and the third generation of protein; these three generations of blowing agents exist and apply simultaneously, none of which is eliminated, and no one completely dominates the blowing agent market. The reason for this blowing agent "Spring and Autumn Period" is that many people lack the basic knowledge of blowing agents, it is challenging to distinguish blowing agents, the choice is disorderly, and the blind ingredients in use are substantial. This means the low-performance blowing agent is not necessarily abandoned, and the high-performance blowing agent is not necessarily preferred. With the rapid development of foam concrete and the gradual popularization of foam concrete knowledge, people will have a deeper, more comprehensive understanding of blowing agents so that their selection and use are gradually rational and scientific. At that time, high-quality and high-performance blowing agents will naturally develop fully, and low-performance blowing agents will automatically exit the market, which is an inevitable result, not people's will to transfer. Advanced things will permanently eliminate backward things; the market is ruthless.
