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.

Calcium Lignosulphonate is a kind of natural anionic surface active agent processed with sulfurous acid pulping waste through advanced production technology. It can work well with other chemicals and produce early strength agent, slow setting agent, antifreeze and pumping agent . It is widely used in various concrete projects such preformed concrete, reinforced concrete and prestressed concrete, especially applicable for commercial concrete, anti-freezing concrete, waterproof concrete, bulk concrete, pumping concrete, with high economic benefit.

Main performance:
1, Can reduce 10% of water consumption at least ;
2, Can improve mixture of the concrete;
3, Compression strength improves by more than 15% equally on 3-28 days;
4, Have no function of corroding on the reinforcing bar.

Operation methods :
1. 0.2-0.5% of mixing amount in concrete (with cement weight), users can adjust the mixing amount through the test ;
2. Can use after mixed liquid , also can put with cement , aggregate into mixer to use at the same time too, need lengthen time properly;
3. The result is more obvious after mixing with high-efficient naphthalene department water-reducing agent. User can determine the suitable dosage according to the result that cement variety, aggregate situation, naphthalene department type of water-reducing agent are tested fixing.

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%

Addition Rates:
Sodium Naphthalene Sulphonate 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 Sulphonate 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.
