Polycarboxylate Superplasticizer Abstract:
The preparation method comprises the following steps: adding unsaturated polyether methyl allyl polyoxyethylene ether, hydrogen peroxide and 2-acrylamide tetradecyl sulfonic acid into deionized water to prepare a base solution; dripping a solution A consisting of acrylic acid, methacrylic acid and a chain transfer agent mercaptoacetic acid and an aqueous solution of vitamin C, stirring uniformly, carrying out a free radical polymerization reaction at the room temperature, and regulating the pH value of the reaction system to be 6-7 by using liquid caustic soda after the reaction is ended, thereby obtaining the polycarboxylate superplasticizer. The polycarboxylate superplasticizer obtained by the invention can maintain long-lasting dispersity, has long branched chains, is good in dispersion stability, simple in preparation process and low in energy consumption, can be synthesized at the room temperature and has good economic benefits.
Characteristics:
As a universal and economical product, JF-PCE is recommended for production of flowing mortars with normal and special cementitious binder system due to the following characteristics
1. Super water reducing effect for cement based material applications
2. Low dosage compared to traditional water reducing agent
3. High dispersion, fluidity and workability.
4. Improvement of early and final strength of cement based system
PCE Advantage:
1. High water reduction rate: its maximum water reduction rate can reach 30%.
2. Good dispersion
3. High adaptability
4. Early strength and high strength
5. High durability
6. Good adaptability
7. Green: No formaldehyde and other harmful ingredients.
Scope of Application:
1. Suitable for long-distance construction projects type pumping concrete.
2. Suitable for compounding normal concrete,high-performance concrete,high-strength concrete and ultra-high strength concrete.
3. Suitable for impervious,antifreezed and high durability concrete.
4. Suitable for high-performance and high flowing concrete,self-leveling concrete,fair-faced concrete and SCC(self compact concrete).
5. Suitable for high dosage of mineral powder type concrete.
6. Suitable for mass concrete that used in expressway,railway,bridge,tunnel,water conservancy projects,ports,wharf,underground etc.
Packaging and Storage:
A. Standard Packing: In 25kg bags inner with PE bags
B. Big Bag or other special packages are possible on request.
