A wave of layoffs that has swept the entire Internet industry has intensified. China's Internet industry has experienced several crises and major changes in the past development process. There is also a "brief history of layoffs by major Internet companies". Hot search, JD.com has a wide range of layoffs in this round of layoffs, and all its subsidiaries are involved. Most of the layoffs are between 10% and 20%. Among them, Jingxi Guangdong and other theaters have all laid off staff. Tencent also reported the news of downsizing and layoffs. Among them, Tencent PCG (Platform User Content Business Group) laid off 30% of its staff, iQiyi laid off 12% of its staff, Kuaishou was reported to have laid off 30% of its staff, and the e-sports department of Station B laid off 90% of its staff.
Mass layoffs on the internet have created a host of socioeconomic issues, including foam concrete.

What are the types of foam concrete foaming agents?

The foamed concrete foaming agent can make concrete appear a lot of foam to accelerate the formation and use of foamed concrete. Use efficiency and speed up the progress of the entire construction project. Foamed concrete foaming agents are available in the market. What are the types of foam concrete foaming agents?

What is foam concrete foaming agent?

The foamed concrete foaming agent is a substance that can make its aqueous solution generate a large amount of foam when the mechanical force is introduced into the air. This kind of substance is a surfactant or a surface-active substance. The former such as anionic surfactants, cationic surfactants, non-ionic surfactants, etc., and the latter, such as animal protein, vegetable protein, pulp waste liquid, and so on. Foamed concrete foaming agent, also known as a cement foaming agent, foam concrete foaming agent refers to an admixture that can reduce the surface tension of the liquid and generate a large amount of uniform and stable foam for the production foamed concrete.

2. What are the types of foam concrete foaming agents?

(1)Rosin resin

This type of foaming agent is made of rosin as the main raw material, and its application has long been common. The chemical structure of rosin is relatively complex, containing rosin acids, aromatic hydrocarbons, aromatic alcohols, aromatic aldehydes, and oxides. Rosin resin foaming agent is also known as an air-entraining agent. Its main varieties are rosin soap and rosin homopolymer. It was initially developed and applied as an air-entraining agent for concrete mortar and later expanded to be used as a foaming agent for foamed concrete.

(2) Synthetic class

Following the rosin-based foaming agents, various synthetic surfactant-based foaming agents have been developed. This type of foaming agent has been widely used in cement foaming abroad since the 1950s. Among various synthetic surfactant foaming agents, the anionic type is generally welcomed due to its fast foaming and large foaming multiple. The cationic foaming agent is expensive and has a certain influence on the strength of cement, so it is not used much.

(3) Protein active substance type

The protein-based foaming agent is the current high-grade foaming agent with good performance and good development prospects. From the general development trend, it will occupy a larger and larger proportion in the application in recent years. Although its price is high, mostly above 15,000 yuan/ton, it will still be accepted by the market due to its better performance.

There are many foam concrete foaming agents, but there are only three or four common ones. The use of foamed concrete foaming agents can accelerate the formation of concrete and quickly make the concrete reach the standard of use, thereby promoting the progress of the entire construction project. , The development of foam concrete foaming agents has gone through a long process, and it is currently widely used in construction projects.

The negative electrode material is the carrier of lithium ions and electrons during the charging process of the battery and plays the role of energy storage and release. In the battery cost, the negative electrode material accounts for about 5%-15%, which is one of the important raw materials for lithium-ion batteries. The global sales of lithium battery anode materials are about 100,000 tons, mainly in China and Japan. According to the current growth trend of new energy vehicles, the demand for anode materials will also show a state of continuous growth. At present, the global lithium battery anode materials are still dominated by natural/artificial graphite, and new anode materials such as mesh carbon microspheres (MCMB), lithium titanate, silicon-based anodes, HC/SC, and metal lithium are also growing rapidly.
Our company provides anode materials and foam concrete. If you need to know more anode materials and foam concrete, please feel free to contact us.
