Sodium Naphthalene Sulfonate Formaldehyde

HIGH-EFFICENCY SUPERPLASTICIZER. APPICATION 1.Used forand widely for self-cured, vapor-cured concrete and its formulation. At the early stage of application,extremely porminent effects areshown. As the result, the modulus and site utilization can be drastically, the procedure of vapor cure is omitted. 2.Suitable for preparation of early-strength,high-strength,high-anti-filtration and self-sealing&pumpable concrete. 3.Widely used in pre-cast&ready-mixed concrete,armored concrete and pre-stressed reinforced concrete in key construction projects such as dam and port construction, road building&town planning projects and dwelling erections etc. 4.Compatible with Portland cement,normal Portland slag cement, fly-ash cement and Portland pozzolanic cement etc. . PROPERTIES FEATURES&CHARACTERISTICS(FDN-C) 1.Appearance:Light brown powder&dark brown liquid.Non-poisonous,odorless,non-flammable and non-corrosive to steel bars. 2.Remarkable Plasticity:As a condition of biending where amount of cement anf collapsibility are fixed aforehand, mixing water can be decreased by 16-22% when it is admixed with reinforced concrete at 0.5-1.0%.Statistically, compression strenth on the lst day,the 3 rd day and the 28th day after single application is increased by 60-95% and 25-40% respectively when it is added at standard blend dosage. As the result,compression strength, tensile strength,bucking strength and modulus of elasticity will be improved to some extent. 3.Improve miscibility of concrete amalgamator with water and collapsibility as well.As a condition of equivalent blending,collapsibility can be increased 4-6 times when it is added at 0.7% blend dosage. 4.15-18% of cement can be reserved when the agent is blended at 0.7% blend dosage,which is preconditioned by same collapsibility and strength.

Alternatively the addition of the agent is followed by water moisturization(water-cement ratio:60%).4.The agent can be combined with other externally applied if pilot development or laboratory experiment succeeds. PACKING,STORAGE AND TRANSPORTATION 1.Package: Power: packing in Woveb fabric bag with plastic inner.Net weight:25kg ± 0.2kg or 50kg ± 0.2kg or 750kg ± 0.2kg Liquid:Sealed plasic drums to prevent accidental leakage and evaporation. The material can be delivered or transported by tank car. 2.Cautions: Prevented from being torn by sharp-ended objects while packages are being transferred or delivered.When being contaminated by high humidity or moisture in case of leakage, it can be prepared in prescribed ways for further use without surrendering any effect. It should be stored in a dedicated warehouse that is well-ventilated and dry.if be affected with damp, just smash or melt it into solution without any bad effection.
