TPEG 2400 is non-toxic and non-irritating, which makes it relatively safe for operators and the environment during production, use, and transportation.
TPEG 2400 is well-soluble in water, can quickly dissolve and evenly disperse in water, and is compatible with various components.
TPEG 2400 has high reactivity and high retention of double bonds, significantly improving the product’s reactivity and thus increasing its utilization rate, reducing production costs.
As a synthetic polycarboxylate superplasticizer, TPEG 2400 is strong at maintaining the dispersibility of cement particles, resulting in low product dosage, high water reduction rate, good fluidity and flow retention of concrete mixtures, and low slump loss.
The polycarboxylate superplasticizer produced from TPEG-2400 has the outstanding advantage of low dosage. At a concrete content of 1.1%, the water reduction rate can reach 30% -40%. Adding a small amount of this water-reducing agent to concrete effectively improves its workability.
A high water reduction rate means that the water consumption can be significantly reduced while maintaining the workability of the concrete. This not only helps to improve the strength of concrete, considerably enhancing its compressive and tensile strength but also improves its durability.
For example, in some high-rise buildings and bridge projects that require high strength, using polycarboxylate superplasticizer containing TPEG-2400 can increase the strength grade of concrete by one or even multiple levels, ensuring the structural safety of the building.
Moreover, compared to traditional water-reducing agents, its dosage can be reduced by 20% -30% in practical applications. Still, it can achieve or even exceed the effect of conventional water-reducing agents, greatly reducing production costs and improving economic benefits.
The TPEG-2400 synthesized water reducer can enhance the internal structure of concrete and make it denser. This enhancement effect is reflected in the improvement of concrete’s early and later strength. The rapid development of early strength is conducive to accelerating construction progress. In contrast, the continuous growth of later strength ensures the long-term stability of the building.
At the same time, it is durable and can effectively resist the damage caused by external environmental factors such as chloride ion erosion and carbonation to concrete, extending the service life of buildings. Moreover, this water-reducing agent will not corrode the steel bars, further ensuring the safety and durability of reinforced concrete structures.
TPEG-2400’s water-reducing agent is another significant advantage in today’s increasingly environmentally conscious world due to its environmental friendliness. Its relatively ecologically friendly production process produces no harmful waste and pollutants.
Due to its high performance, concrete can reduce the amount of cement used, thereby reducing carbon emissions in the cement production process. In addition, its use in concrete will not pollute soil, water bodies, etc., which meets the requirements of sustainable development and is conducive to promoting the development of green buildings.
TPEG-2400 is usually a colorless and transparent liquid, and its pure appearance indicates that the product has high purity and low impurity content. The stability of color also reflects the quality control level of the product during production and storage.
A stable color helps ensure its consistency and reliability in the synthesis process of polycarboxylate superplasticizers.
The hydroxyl value is an essential indicator for measuring the hydroxyl content in TPEG-2400 molecules, generally between 45-55mgKOH/g. The appropriate range of hydroxyl values ensures its activity in polymerization reactions and reactivity with other monomers.
The acid value reflects the content of acidic impurities in the product. It usually requires a low acid value, generally not exceeding 0.5mgKOH/g, to avoid adverse effects on the polymerization reaction and water-reducing agent performance.
The retention rate of double bonds is one of the key quality indicators of TPEG-2400, which directly affects the synthesis efficiency and performance of polycarboxylate superplasticizers.
A high retention rate of double bonds (generally required to be greater than 90%) ensures sufficient active double bonds to participate in the polymerization reaction, thereby ensuring the stability of the molecular structure and properties of the water-reducing agent.
The retention rate of double bonds is closely related to process control, storage conditions, and other factors during the production process.
The moisture content must be strictly controlled at a low level, usually not exceeding 0.1%. The presence of water may cause a series of problems, such as side reactions between water and monomers during the synthesis of polycarboxylate superplasticizers, leading to decreased product performance and uneven molecular weight distribution.
Therefore, precise control of moisture content is essential in ensuring the quality of TPEG-2400.
The molecular weight distribution of TPEG-2400 is relatively narrow, with an average molecular weight (Mw) generally between 2200 and 2600 and an average molecular weight (Mn) between 1800 and 2200.
This narrow molecular weight distribution helps ensure consistency and stability in the performance of polycarboxylate superplasticizers, allowing concrete to maintain similar workability and strength characteristics in different production batches.
Unsaturation reflects the content of double bonds in TPEG-2400 molecules, generally between 0.4 and 0.6 mmol/g. The appropriate degree of unsaturation significantly impacts its activity in polymerization reactions and its ability to copolymerize with monomers such as acrylic acid, which in turn affects the molecular structure and properties of polycarboxylate superplasticizers.
The product’s pH value is usually controlled between 5 and 7, which is slightly neutral. A stable pH value helps maintain the product’s chemical stability, preventing chemical reactions such as hydrolysis and oxidation during storage and use, thereby ensuring that its performance is not affected.
The requirement for peroxide content is extremely low, generally not exceeding 10ppm. Peroxides may cause free radical reactions, leading to product deterioration, uncontrolled polymerization, and other issues.
Therefore, strict control of peroxide content is crucial to ensure the quality and stability of TPEG-2400.
The content of metal ions such as sodium and potassium should be controlled at a low level, generally not exceeding 10 ppm. Metal ions may affect the progress of polymerization reactions and the performance of water-reducing agents, such as causing product discoloration or reducing dispersibility.
Therefore, strict control of metal ion content helps ensure the stability and reliability of product quality.
The residual amount of polymer should be as low as possible, generally not exceeding 0.5%. Polymer residues may affect the purity and reactivity of TPEG-2400, thereby adversely affecting the performance of polycarboxylate superplasticizers.
Therefore, adequate measures must be taken to reduce polymer residues in the production process.
TPEG-2400 plays an indispensable role in the production of high-performance commercial concrete. It can enable concrete to maintain good workabilities, such as high fluidity, permeability, and self-compaction while having high strength.
This allows concrete to better fill every corner of the formwork during the pouring process, avoiding quality defects such as honeycombing and rough surfaces.
In high-rise buildings, large-span bridges, and water conservancy engineering requiring highly concrete performance, polycarboxylate superplasticizers containing TPEG-2400 can ensure project quality, improve construction efficiency, and reduce construction costs.
For precast concrete component manufacturing enterprises, TPEG-2400 helps to produce high-strength and high-quality precast components. In producing prefabricated beams, slabs, columns, and other elements, this polyether monomer synthesized water reducer can accurately control the water consumption and water cement ratio of concrete and improve the compactness and strength of concrete.
TPEG-2400 has also demonstrated unique advantages in special concrete projects, such as marine engineering, underground engineering, and high-temperature environment engineering.
