Sodium Naphthalene Formaldehyde (SNF-Superplasticizer for Concrete)
CAS Code: 36290-04-7
SNF a high range water reducer, commonly referred to as a super plasticizer, also named Naphthalene Sulphonate Formaldehyde Condensate (short name: SNF, PNS, NSF, etcâ?¦)
SNF is made from naphthalene, sulfuric acid, formaldehyde and liquid alkali, through sulfonation, hydrolyzation, condensation and neutralization reaction and then drying to powder. SNF-A5% contains very small chloride. Thus, it meets the requirements of chemical admixture specifications for concrete: ASTM Designation C 494 as a Type F admixture, GB8076-2008 and GB50119-2003.
Usage

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.

The raw material naphthalene superplasticizer (SNF/FDN/PNS) has strong dispersion effect on cement particles and good use effect of preparing super flowing concrete as well as cast-in-situ concrete and precast members with early strength and high strength requirements, can comprehensively improve various properties of the concrete, and is widely applied to highways, bridges, dams, harbors, tunnels, electric power, water conservancy as well as industrial and civil architecture, steam-cured and naturally-cured precast members and so on.

1. Construction:
1. Widely used in precast & ready-mixed concrete, armored concrete and pre-stressed reinforced concrete in key construction projects such as dam and port construction, road building & town planning projects and dwelling erections etc.
2. Suitable for preparation of early-strength, high-strength, high-anti-filtration and self sealing&pumpable concrete.
3. Used for and widely for self-cured, vapor-cured concrete and its formulations. At the early stage of application, extremely prominent effects are shown. As the result, the modulus and site utilization can be drastically, the procedure of vapor cure is omitted in peak heat summer days. Statistically 40-60 metric tons of coal will be preserved when a metric ton of the material is consumed.
4. Compatible with Portland cement, normal Portland cement, Portland slag cement, flyash cement and Portland pozzolanic cement etc.

Others:
Because of the high dispersion force and low foaming characteristics, SNF has also been widely used in other industries as Anionic Dispersing Agent.
Dispersing agent for disperse, vat, reactive and acid dyes, textile dying, wettable pesticide,paper,electroplating, rubber, water-soluble paint, pigments,oil drilling, water treatment,carbon black, etc.

Sodium sulfate content:
1. If the content is large, it may crystallize at low temperature which blocks pipes and valves, and reduces the water reducing capacity and strength.Because the solubility is affected by temperature change.When the outdoor temperature is below 20, the solubility will drop suddenly. When the outdoor temperature is below 16, the crystal of sodium sulfate is obvious.During crystallization, some effective components of naphthalene series superplasticizer will be adsorbed, which will affect the water reducing ability and strength of concrete.

Vamcell TM HPMC is made by propylene oxide, methyl choride with alkali-cellulose after a chemical process called etherification under rigidly controlled conditions. The resultant nonionic polymer is purified , dried and ground to a fine white powder, this water-insoluble cellulolse is turned into water-soluble nonionic polymer. HPMC is a good film-former and varies somewhat in physical and chemical properties. HPMC is quite hydrophilic and readily soluble in cold water.
VAMCELLTM Cellulose Ethers for Tile Adhesive provide:

Excellent wetting property

Excellent green adhesive bond strength on different substrates, including plywood.

Increased plastic behavior and flexibility

Increased cohesive force

Excellent open time and sag resistance
