Poly Naphthalene Sulfonate Formaldehyde Poly Naphthalene Sulfonate Formaldehyde,PNS, SNF, FDN Product Name: Poly Naphthalene Sulfonate Formaldehyde Descriptions: Poly Naphthalene Sulfonate Formaldehyde Description High Range Water-Reducing Admixture Poly Naphthalene Sulfonate Formaldehyde Condensate,Concrete Admixture Uses 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 Poly Naphthalene Sulfonate Formaldehyde Specification: Solid Content *2% min Moisture 8.0 % max Fineness 5.0% max PH value 7 - 9 Chlorides Content 2.0% max Surface Tension ****2 Mn/m Cement Flowing Rate **0mm min Concrete Reducing Water Rate *8% min Sodium Sulfate Content *8% max (5%max is also available) Addition Rates 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.*5%. Poly Naphthalene Sulfonate Formaldehyde Direction Prepare solutions as required. Direct use of powdery agent is allowed. Alternatively the addition of the agent is followed by water moisturization (water-cement ratio: *0%). The agent can be combined with other externally applied agents if pilot development or laboratory experiment succeeds.
