What is Water Reducer?

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 Water reducer.

Introduction to Water Reducer:

Water reducer, or water reducing agent, concrete water reducer, cement water reducer, is a special chemical product added to the concrete mixture before pouring, belonging to a kind of concrete admixture. A concrete admixture is a chemical that is added during the concrete-making process to improve concrete performance. Admixtures in concrete are small (no more than 5%) but indispensable. The compound water reducing agent is mainly used in ready-mixed concrete, which is used in infrastructure construction and real estate construction.

According to the water reduction rate, the water reducer is divided into ordinary water reducer (the first generation), efficient water reducer (the second generation), and polycarboxylic acid (also known as superplasticizer) high-performance water reducer (the third generation).

The first generation of water reducer is lignosulfonates, which have been used since the 1930s and are cheap products derived from the wood and paper industries. 

Due to the excellent slump performance and environmental protection and pollution-free processing process, the polycarboxylic acid series water-reducing agent quickly replace the naphthalene series water-reducing agent has become the mainstream water-reducing agent at present, the production of polycarboxylic acid series water-reducing agent has accounted for nearly 80%. 

Production Process of Water Reducer:

High-performance water reducing agents and efficient water reducing agents are compounded by their mother liquor, the raw materials of their mother liquor are polyether monomer and industrial naphthalene, polyether monomer also need to be further synthesized by ethylene oxide.  Industrial naphthalene is produced from coal chemicals, and there are currently three ways to produce ethylene oxide, including petrochemical, coal-chemical, and alcohol processes. 

There are some technical barriers to chemical synthesis and physical compounding of the two main production processes of water-reducing agents.

Chemical synthesis involves polymerization technology in the field of polymer chemistry. In the research and development and production of products, relatively professional personnel are required, and long-term technical experience and industrial scale-up production experience are required.

Advantages of Water Reducer:

Under the condition of constant cement content, the water reducer can reduce water consumption and improve concrete strength. Under the condition of constant workability and strength, the admixture of cement dosage can be saved. 

1. Reduce water content by 5-10%;

2. Reduce the porosity of concrete;

3. Increase concrete strength by up to 25% (because the concrete mixture requires less water to remain processable);

4. Increased workability (assuming free water remains constant);

5. Reduced water permeability (due to less water used);

6. Reduce the diffusion of the corrosive agent in concrete, so as to improve the durability of concrete;

7. Provide a better finish to the surface.

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 Water reducer. If you need to know more anode materials and Water reducer, please feel free to contact us.
