Polycarboxylate Superplasticizer Product overview:

XRT-D polycarboxylate superplasticizer mother liquid  is a new generation of polycarboxylic acid superplasticizer, 

which is synthesized by free radical polymerization of polyoxyethylene ether macromonomer, unsaturated acid and sulfonic acid monomer. The product has a very high water reduction rate and low slump loss performance, which can ensure the high water reduction rate required for the preparation of concrete, and can be widely used in pumped concrete, superfluid self-compacting, high strength and high performance concrete and commercial concrete.

Polycarboxylate Superplasticizer Technical principle:

The product has a comb structure, the molecule has a longer length is polyoxyethylene long chain and high density sulfonic acid group, so that it has a greater steric hindrance and electrostatic repulsion effect, providing greater dispersion and higher water reduction rate for cement.

Polycarboxylate Superplasticizer Product characteristics:

1.Extremely high water reduction rate The product has a great dispersion and a very high water reduction rate 

Polycarboxylate Superplasticizer  (water reduction rate can reach more than 40%), which provides a guarantee for the Polycarboxylate Superplasticizerpreparation of high-grade concrete.

2.Excellent workability Fresh concrete high fluidity, easy to pour and dense, can effectively reduce the viscosity of concrete,     good cohesion, moderate gas content, suitable for pumping;

3.Concrete has high strength at various ages, good volume stability, and outstanding impermeability, freeze-thaw 

   resistance, corrosion resistance and carbonization resistance;

4.Wide adaptability to Portland cement, ordinary Portland cement, slag silicate, fly ash cement, pozzolanic cement and  

   various admixtures have a wide range of adaptability.

5.The raw materials used in green and environmental protection are non-toxic and harmless, and no three wastes are 

    produced in the production process.

Polycarboxylate Superplasticizer Usage:

The usual dosage is 0.5%-1.0% (according to the total amount of gelled material), and the

best dosage should be determined by test according to the engineering materials and

characteristics;

The water-reducing agent can be dissolved in water or added to the concrete mixer alone.

It can be combined with high plasticity polycarboxylic acid superplasticizer, lignosulfonate

superplasticizer and various retarding agents.

Polycarboxylate Superplasticizer Packing and storage:

The liquid of this product is sealed in 200KG and 1000KG drums.

Anti-leakage, anti-exposure and anti-high temperature during storage.

The shelf life is one year and can be used only after passing the inspection.

This product is alkali-free liquid, non-toxic and non-corrosive. Products without pollution to the environment.
