We have exported more than 10,000mt Polycarboxylate superplasticizer (PCE) 50% liquid and powder per year, which has been shipped to South America, South East Asia, Russia etc.
Polycarboxylate Superplasticizer (PCE) is a kind of superplasticizer emerged in the early 80's. It is mainly used in cement concrete. In chemistry, Poly-carboxylate-based is an organic and polymeric electrolyte. It belongs to a polymer surfactant. Therefore, it can also be applied in other paste materials such as gypsum products and ceramic products to reduce water content.
Poly-carboxylate is a weak electrolyte. It can only be fully dissolved in an alkaline solution. It can compound with cations in cement/water system to control the cement hydration process and thus to reduce the slump loss of the concrete. Poly-carboxylate achieves its water reducing effect through the yield of electrostatic repulsion and steric hindrance when it is absorbed to the cement particles. Hence, Poly-carboxylate is the most effective superplasticizer for cement concrete.
Poly-carboxylate is a raw material for superplasticizer. It is recommended that applicants should determine the Poly-carboxylate dosage in their own formulation according to their trial runs.
Why use Polycarboxylate superplasticizer ? As follows:
1) High early strength: significant increase of early strength and 28d strength
2) Low slump lose: Great reduction of slump lose
3) Excellent durability: Reduction of cracking, shrinkage and creep
4) High water reduction: Water reduction more than 30% according to different application
5) Environmental-friendly products: Non pollution during production
6) Excellent compatibility with various types of cements
7) Low chloride and alkali content, no corrosion to steel-bar
