Polycarboxylate-based High-performance Water Reducing Agent

As the world deals with potential supply shortages, oil prices are soaring again, with more dramatic spikes and sudden drops expected.

For consumers, that means more expensive gas for longer - prices at the pump remain above $4 a gallon. For the economy, that means more inflation. In addition to the pressure on consumers, any business that relies on oil -- from airlines and truck drivers to chemical companies and plastics producers -- will face higher costs.

Mr Pickering estimates that 2m to 3m barrels a day of Russian oil shipped by water are frozen out of the market with no direct buyers. Due to the soaring oil price, the price of the water reducing agent in the chemical industry will also be greatly affected. He said China and India are continuing to buy Russian crude. "I'm sure there will be others willing to take on more over time," he said. Mr Pickering said he did not expect oil to return to $130 a barrel, but added that it could happen. Francisco Branch, head of commodities and derivatives at Bank of America, said the US market was ready for cyclical price spikes and price swings in the water reducing agent.

Concrete Additives:

Using concrete additives is the most effective, economical, and simple technical way to reduce the cement dosage, improve the utilization rate of industrial waste residue, and realize the high durability and performance improvement of concrete. It is a necessary material for manufacturing modern concrete. It is regarded as the third breakthrough of concrete technology after reinforced concrete and prestressed reinforced concrete. 

 

Development Course of Water Reducing Agent: 

As one of the most important concrete additives, water reducing agent plays an irreplaceable role in the development of modern concrete. Since the 1960s, Japan and Federal Germany have developed β -naphthalene sulfonate formaldehyde condensates and melamine-formaldehyde condensates superplasticizer, commonly known as high efficient water reducing agent, resulting in the worldwide high efficient water reducing agent research, development, and application of the boom.

This kind of traditional polyelectrolyte water-reducing agent, including naphthalene, melamine, sulfamate, and lentisulfonate, has a good working performance for fresh concrete, has been continuously developed and applied for more than 30 years, and still occupies a certain market share. At that time, due to the limitations of their own structure and dispersive mechanism, they had a series of insurmountable problems, such as large slump, large shrinkage, and environmentally unfriendly.

Later, the development of polymer synthesis technology accelerated the development of new efficient water reducing agents. In the early 1980s, Japan took the lead in successfully developing polycarboxylate series water reducing agents. This new generation of polycarboxylate superplasticizer overcomes some disadvantages of traditional superplasticizers and has such outstanding advantages as low yield, good slump protection performance, the low shrinkage rate of concrete, and strong adjustability of molecular structure, large potential of high performance, and no use of formaldehyde in the production process. It is the developing direction of high-performance concrete admixture at present.

 

Introduction to Polycarboxylate-based High-performance Water Reducing Agent:

Polycarboxylate-based high-performance water reducing agent is defined as containing carboxylic unsaturated monomer and other monomer copolymerization. It is a type of water reducing agent with excellent performance used to help concrete with reducing water, collapse protection, strengthening, shrinkage, and environmental protection.

According to the invention patents all over the world, polycarboxylate-based high-performance water reducing agents can be divided into two categories according to the structure of the main chain: 1. Polyether with acrylic acid or methacrylic acid as the main chain grafted with different side chain lengths. 2. Polyether with maleic anhydride as the ink branch with different side-chain lengths. At present, the main differences of polycarboxylate products on the market lie in: the main chain chemical structure and length, side-chain type, length and graft density, Ionic group content, molecular weight size, and distribution. Because the molecular structure of polycarboxylate has a large degree of freedom, it possesses the potential for high performance.

For Germany, the largest economy in Europe, the impact of the Russian-Ukrainian conflict on the natural gas market is the most obvious. This also exposed the serious dependence of some German industrial enterprises on Russian natural gas. Some analysts pointed out that the instability of natural gas supply has had a big impact on the German economy and threatened its market competitiveness because alternative energy supplies will not be cheap and difficult to come quickly. Increased uncertainty over natural gas supplies is putting enormous pressure on German manufacturers in sectors ranging from steelmaking to chemical production, especially Germany's large number of small and medium-sized companies.

There will be no shortage of water reducing agents for the time being, but the market demand for water reducing agents in the future will also change with the influence of various external factors. If you need water reducing agents, please feel free to contact us.
