Sodium Naphthalene Sulphonate Formaldehyde

The naphthalene-based superplasticizer is a non-air-entraining high-efficiency water reducing agent synthesized by the chemical industry. Chemical name Naphthalene sulfonate formaldehyde condensate, which has strong cement particle dispersibility.

Description

Sodium Naphthalene Sulfonate Formaldehyde

(SNF-A/C)

CAS No.: 36290-04-7

HS Code: 38244010

All the names:

Sodium Naphthalene Sulphonate Formaldehyde, Poly Naphthalene Sulfonate Formaldehyde Condensate, Naphthalene Sulfonic Acid Formaldehyde, Na Naphthalene Sulphonate Formaldehyde, Na Naphthalene Sulfonate Formaldehyde, Naphthalene Sulphonate SNF/PNS/FND/NSF

Brief introduction: SNF is high range water reducer, commonly referred to as a super plasticizer.

It is made from naphthalene, sulfuric acid, formaldehyde and liquid alkali, through sulfonation, hydrolyzation, condensation and neutralization reaction and then drying to powder. SNF-A 5% 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.

    Application:

  • When the strength and slump are basically the same, the amount of the cement can be reduced by 10-25%
  • When the water-cement ratio is constant, the initial slump of concrete can be increased by more than 10cm, and the water reduction rate can reach up to 15-25%
  • SNF has significant early strength and enhancement effect on cockroaches, and its intensity increase range is 20-60%
  • It can improve the workability of concrete and improve the physical and mechanical properties of concrete
  • It has good adaptability to various types of cement and good compatibility with other types of concrete admixtures
  • Others: In the leather, textile and dye industries, it can also be used as a dispersant
  • Especially suitable for: fluid concrete plasticized concrete, steam curing concrete, impervious concrete, waterproof concrete
