Detailed Introduction

YL-PCE-WR-聚羧酸高效减水剂

YL - PCE - WR poly carboxylic acid water reducing agent for liquor (high water reducing type)


Poly (carboxylic acid type water reducer high water reducing

          using polyoxyethylene ether monomers, unsaturated acid and sulfonic group monomer by radical polymerization and become a new generation of poly carboxylic acid high performance water reducing agent.Product has high water reducing rate and low slump loss performance, can guarantee the preparation needed for the concrete high water reducing rate, can be widely used in pumping concrete, superfluid state self-compacting and high strength high performance concrete and concrete products.
         Products with comb structure, molecular using a longer length is polyoxyethylene long chain and high density sulfonic acid group, make greater space steric hindrance and electrostatic repulsion, provides a more decentralized and higher cement water reducing rate.


A, product characteristics


           High water reducing rate of the product has a great dispersion and high water reducing rate (water reducing rate can reach more than 40%), guarantee for the preparation of high grade.Excellent workability: fresh concrete high liquidity, easy pouring and close-grained, can effectively reduce the viscosity of concrete, good adhesiveness, air content is moderate, is suitable for pumping;Concrete each age concrete hardening and durable performance is good, high strength, good volume stability, impermeability and freeze resistance, corrosion resistance and carbonation resistance;Wide adaptability of Portland cement, ordinary Portland cement, slag Portland cement, fly ash, ash, cement and various admixtures are widespread adaptability.Green, environmental protection, non-toxic harmless, the materials produced in the production process has no "three wastes".

Three, scope of application

         1, is suitable for the preparation of early strength concrete, retarded, precast concrete, concrete, concrete, flow state of self-compacting concrete, mass concrete, high-performance concrete and concrete, all kinds of industrial and civil construction of cast-in-site concrete pre mixing.Especially suitable for low grade commercial concrete.
         2, can be widely used in high-speed rail, nuclear power, water conservancy and hydropower engineering, subway, Bridges, highways, harbor wharf and other national large and key projects.

Fourth, use method and matters needing attention

        1, common content is 0.5% - 1.0% (in total gelled material), should be based on the characteristics of engineering materials and, in order to test to determine the best content;
        2, water reducing agent can dissolve in water, also can join the concrete mixer alone;
        3, with hi-fi plastic poly carboxylic acid water reducing agent, lignosulfonate water reducing agent and various compound with using retarder.
        4, the company provides a full range of use of technology, can be training for the user, if there are any problems, have engineer door-to-door guidance.

Five, packaging, storage and transportation

        1, this product is liquid, for 220 kg/barrel and 1.1 tons/barrels of seal.
        2, storage process leakage, prevent sun, anti high temperature;
        3, guarantee period is one year, expired inspection qualified rear can use.
        4, this product is no alkali liquid, non-toxic, non-corrosive, non-polluting products to the environment, but not edible.
        5, suitable for all kinds of civil and commercial concrete mixing station.
