Sodium Naphthalene Sulfonate Formaldehyde (SNF/PNS/NSF/FND)
Sodium naphthalene sulfonate formaldehyde (SNF), also known as SNF superplasticizer, naphthalene based superplasticizer, sodium naphthalene, naphthalene sulfonate, poly naphthalene sulfonate (PNS), sodium naphthalene formaldehyde, sulphonated naphthalene formaldehyde, naphthalene sulfonate formaldehyde (NSF),etc. SNF is widely used in the
SNF Sodium Naphthalene Sulfonate Formaldehyde-Bailin Group
CAS Code: 36290-04-7. HS Code (CN): 38244010. SNF a high range water reducer, commonly referred to as a super plasticizer, also named Naphthalene Sulphonate Formaldehyde Condensate (short name: SNF, PNS, NSF, etc…) SNF is made from naphthalene, sulfuric acid, formaldehyde and liquid alkali, through sulfonation, hydrolyzation, condensation and

Sulphonated Naphthalene Formaldehyde Condensate
Figure 7.13 shows the SEM images of hardened cement paste doped with different SPs (SNF, PCs, and SCS) at 28 d. For the blank sample, the SEM image indicates that the hardened cement paste mainly has a loose porous structure and exhibits few small rod-like crystals (Figure 7.13(a)), With SNF at 0.9% bwoc, there are many rod-like crystals blocked in the matrix of the cement paste, and it shows
Sodium Naphthalene Sulphonate Industrial Grade -Bailin Group
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
- What is Sulphonated naphthalene formaldehyde?
- Sulphonated naphthalene formaldehyde, also known as naphthalene superplasticizer or SNF superplasticizer, is a high-range water reducing admixture for concrete. It has the advantages of high water reduction rate, neither retardation nor air entrainment, and strong adaptability.
- How to use Sulphonated naphthalene formaldehyde superplasticizer?
- Use SNF powder directly, or add it after the cement aggregate is fully moistened with 60% mixing water. The sulphonated naphthalene formaldehyde superplasticizer has good adaptability with other concrete chemical admixtures.
- What is sodium naphthalene sulfonate superplasticizer?
- The sodium naphthalene sulfonate superplasticizer can be used directly or dissolved in water first and used as a solution-type admixture, which is suitable for various construction environments or mixer types.
- What is naphthalene based superplasticizer?
- In addition, naphthalene based superplasticizer has good adaptability with other admixtures and can be widely used as the composition of composite admixtures, such as, pumping agents, waterproofing agents, air entraining water reducing agents and antifreeze agents, etc. More than 15 years of export experience.
- What is sodium naphthalene sulfonate water reducing admixture?
- Sodium naphthalene sulfonate can improve the workability of concrete and comprehensively improve the physical and mechanical properties of concrete. Naphthalene formaldehyde sulfonate water reducing admixture has good adaptability to various cements and good compatibility with other types of concrete admixtures.
- Can naphthalene superplasticizer be made into a liquid without crystallization?
- The naphthalene superplasticizer can be made into a liquid without crystallization in winter, which solves the problem of pipeline blockage caused by sodium sulfate crystallization in winter concrete manufacturing, and provides convenience for winter concrete construction.
