We are offering sodium naphthalene sulphonate formaldehyde - a. index items standard value test resultsappearance yellow brown powder meets the requirementph value 7--9 8.3solids content (%) 93%min 96.42net starch fluidity(mm) 260min 273content of cl- (%) 0.3% max 0.25na2so4 content (%) 5%max 4.4surface tension (n/m) (71 1) 10 -3 (71 1) 10 -3conclusion complies with requirements . product description high range water-reducing admixture sodium naphthalene formaldehyde, poly naphthalene sulfonate formaldehyde condensate, concrete admixture uses sodium naphthalene 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. sodium naphthalene 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 addition rates sodium naphthalene 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%. sodium naphthalene 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: 60%). the agent can be combined with other externally applied agents if pilot development or laboratory experiment succeeds. sodium naphthalene formaldehyde package, storage & handling for powder: woven fabric bag with plastic liner. net weight: 25kg +/- 0.1 kg.
