1. Thinning performance
Test results indicate the thinning performance in fresh water based mud under normal temperature is comparable to ferrochrome lignosulfonate (fcls). At elevated temperature, it performs better than fcls in either fresh water or salt-water based mud, particularly the later. The product is suitable for use in drilling under complex geological formation, in water with high tds, or in offshore drilling.
2. Good fluid loss control properties
Its major advantage is the thinning effect in drilling mud with high solid content, and simultaneously controls the fluid loss. Its fluid loss control action is better than fcls and the mud cake formed is smooth and compressible, thus beneficial for well bore protection and fluid loss reduction under high-pressure condition.
3. Higher retention of solid
The product has improved solid retaining capacity due to its excellent thinning properties. Even when the mud is mixed with large quantity of clay while drilling, the rock scarps can still maintain good mobility. In addition it is capable of withstanding contamination by calcium, magnesium and sodium electrolytes, making it an ideal thinning agent for heavy weight mud.
4. Recommended dosage
For salt water and fresh water based mud, a range of 0.5 to 1.0% is recommended depending on the specific conditions. Under special situations such as high solid and metal electrolytes content, a slight increase in dosage is recommended but not to exceed 2.0%.
5. Packing
It is packed in 25 kg net weight moisture proof multi-wall paper bags, with pe film inside. Other size packing is also available on request.

Product Description
High Range Water-Reducing Admixture
Sodium Naphthalene Sulphonate Formaldehyde, Poly Naphthalene Sulfonate Formaldehyde Condensate,Concrete Admixture
Uses
Sodium Naphthalene Sulphonate 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 Sulphonate 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
Sodium Naphthalene Sulphonate Formaldehyde Specification:
Solid Content :96.42%
PH value :8.3
Chlorides Content :0.25%
Sodium Sulfate Content :4.4%.
For powder: woven fabric bag with plastic liner. Net weight: 25kg +/- 0.1 kg.
