poly naphthalen sulfonate formaldehyde - Product

Place of Origin : Wuhan,China

Product Description

Poly Naphthalene Sulfonate Formaldehyde is high range water-reducing and an anion surface active agent based on polyalkyaryl- sulphonate.

Poly naphthalene sulfonate is a high range concrete admixture of concrete cast-in-place, prefabricating, pump and curing. It has a good adaptability to various cements and PNS is no erodent to reinforcing bar and nonpoisonous and pollution-free. It has been applied to the highway, bridge, tunnel, water conservancy hydroelectric project, port, quay.

Physical Specification

Other Specification : Technical Spefication: Solid Content 92% Min Moisture 8.0 % Max Fineness 5.0% Max PH Value 7 - 9 Chlorides Content 2.0% Max Surface Tension 68-72 Mn/m Cement Flowing Rate 230mm Min Concrete Reducing Water Rate 18% Min Sodium SulfateContent 18% Max (5%max Is Also Available) Poly Naphthalene Sulfonate Formaldehyde Produces Concrete With Extremely Workable Characteristics Referred To As High Slump. PNS Also Allows Concrete To Be Produced With Very Low Water/cement Ratios At Low Or Normal Slumps Poly Naphthalene Sulfonate Formaldehyde Is Ideal For Use In Prestress, Precast, Bridge Deck Or Any Concrete Where It Is Desired To Keep The Water/cement Ratio To A Minimum And Still Achieve The Degree Of Workability Necessary To Provide Easy Placement And Consolidation. Poly Naphthalene Sulfonate Formaldehyde Can Be Added Directly Or Added In After Melt. It Can Be Added During Mixing And After-mixing. The Afterward Approach Can Achieve Better Result. The Suggested Addition Rate Is 0.75%. Direct Use Of Powdery Agent Is Allowed. Alternatively The Addition Of The Agent Is Followed By Water Moisturization (water-cement Ratio: 60%). The Agent Can Be Combined With Other Externally Applied Agents If Pilot Development Or Laboratory Experiment Succeeds.
