According to different molecules, water reducing agents can be divided into the first generation of ordinary water reducing agents represented by lignin, the second generation of superplasticizers represented by naphthalene series and the third generation of water reducing agents represented by polycarboxylic acid series. Substitute high performance water reducer.
The first generation of lignin-based superplasticizers has gradually withdrawn from the stage of history; the second generation of superplasticizers is represented by naphthalene series, in addition to aliphatic, sulfamate and other superplasticizers.
Naphthalene-based superplasticizer in concrete has the advantages of high water-reducing rate and strong adaptability to various cements, and have occupied the mainstream for a long time in my country. Since 2006, the third-generation polycarboxylic acid-based high-performance water reducer has developed rapidly and has now become a mainstream product in the market, accounting for 78% of its output in 2017.
Compared with naphthalene series, polycarboxylate superplasticizer in concrete has more hydrophilic active groups in the side chain due to its comb-like molecular structure, compared with the linear molecular structure of naphthalene series, and the steric resistance is larger. It is more difficult to coagulate again, and the dispersion performance is stronger, so the dosage of polycarboxylate superplasticizer is lower and the water reduction rate is higher.
In addition, as the polycarboxylate upstream raw material ethylene oxide broke the monopoly of PetroChina and Sinopec, and began to adopt technical routes such as alcohol method and coal chemical industry, the era of huge profits for ethylene oxide has ended, and the cost and price of polycarboxylate It is significantly reduced, which further promotes the replacement of traditional naphthalene-based water-reducing agents by polycarboxylic acid-based water-reducing agents.
In recent years, the manufacturers of superplasticizers inside and outside the market are developing products and expanding the market, and the production and supply capacity has increased significantly. At present, the production and supply system of raw materials in my country has been established, and the development of polycarboxylate superplasticizers in my country in the next few years already has a solid raw material foundation.
Another main raw material of polycarboxylate superplasticizer in concrete is methacrylic acid and acrylic acid. At present, the relevant manufacturers in my country are strengthening the quality and expanding the scale, which will meet the market demand.
my country’s high-efficiency water-reducing agent export market has developed for many years and has been exported to more than 100 countries around the world, but the export destination countries are mainly developing countries such as the Middle East, Southeast Asia, and Africa. Opportunities are always accompanied by risks.
Although the export of concrete admixtures in my country has formed a certain scale, with the continuous expansion of the export scale, more and more problems are gradually exposed. The impact of a series of problems such as the turbulent international financial environment and rising costs on exports cannot be ignored. How to seize opportunities and avoid risks is a problem that the industry must seriously consider.
Only by breaking through these challenges can we seek business opportunities in the fiercely competitive international market.

SLES 70% is a specific concentration of Sodium Lauryl Ether Sulfate (SLES), which is a commonly used surfactant in many personal care and household cleaning products.
Plasticizers are additives that are added to a polymer matrix to increase its flexibility, toughness, and workability.
Polycarboxylate superplasticizer, a vital ingredient in the construction industry, plays a key role in enhancing the workability and performance of concrete.
Alkylbenzenesulfonic acids are a type of organic compound that has a benzene ring with a sulfonic acid group and an alkyl chain attached to it.
