Product Description

Naphthalene sulfonate is a β-naphthalene sulfonate formaldehyde condensates, soluble in water, stable physical and chemical properties with good effect. Short for SNF/PNS/FDN/NSF, and also be named as sodium naphthalene sulfonate formaldehyde condensate/naphthalene superplasticizer/naphthalene sulfonic acid. HS code: 3824401000; CAS: 36290-04-7. There are four solid content SNF offered: SNF-A (Na2SO4<5%); SNF-B ( Na2SO4<10%); SNF-C (Na2SO4<16%, Na2SO4<18%).

As high performance concrete additives/concrete admixtures, sodium naphthalene sulfonate formaldehyde condensate has high dispersion, low foaming characteristics, high water reduction, strength, early strength, enhance superior, cement adaptability. The incorporation of this product greatly increases concrete mobility, improve slump, ensure the workability. Mainly used to coloring for vat dyes, reactive dyes, acid dyes, acid staining pad or pigment pad dyeing of the dispersing agent, as a auxiliaries for vat dyes's powder or sizing agent. Also used staining to levelling agent and auxiliary tanning agent in leather industry.

Application

Sodium naphthalene sulfonate formaldehyde condensate is one of the basic ingredients for formulation of chemical admixtures for concrete and mortars. Suitable for plain concrete, reinforced concrete, prestressed concrete, high performance concrete, SNF is used for all types of concrete. The main application of Sodium Polynaphthalene Sulfonate is the production of admixtures for ready-mixed concrete. Besides, it`s also used as concrete additives/concrete admixtures: mortar admixture, concrete water reducing agent, concrete superplasticizer, retarder, concrete admixture raw material etc.:

1. Same concrete substantially of strength and slump, can reduce the amount of cement 10-25%.

2. In the same watercement ratio, the concrete initial slump raises 5-8 multiples.

3. To improve the workability of concrete, improve the physical and mechanical properties of concrete.

4. Good adaptability to various cement, and other various types of concrete admixtures compatibility is good.

5. Suitable for the following concrete projects: flowing concrete, plastic concrete, steam curing concrete, impervious concrete, waterproof concrete, nature conservation precast concrete, reinforced and prestressed concrete, high strength ultra-high strength concrete .

6. Mixing amount is 0.5%-1% of cement dosage, water reduction rate is 18-28%; to improve the strength of concrete increases with 60%-90% in 1-3 days, 25%-60% after 28 days, long-term strength is still keeped.
