Product Description

Sodium naphthalene sulfonate formaldehyde for textile & leather

 

Product description:

1.SNF is made of naphthalene, sulfonic acid, formalin and alkali, through sulphuration, hydrolyzation, condensation and neutralization reaction. 
2.SNF have many advantage of :no chloride,good dispersion, water reduction and early-strength effect,good dispersion, water reduction and early-strength effect,without air entraining , no corrosion on steel bars , good compatibility with portland cement .

Application:

Ø Produces the high slump flowing concrete with no loss in strength.Produces low water/cement ratio concrete with high strengths.

Ø Ideal for using in high strength concrete, flowing concrete, early strength concrete, precast steam curing concrete, prestressed concrete etc. 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.

Ø Be used as basic material to produce others compound admixtures, (such as accelerating and water-reducing admixture, retarding and water-reducing admixture, pumping antifreeze and pumping water-reducing admixture, etc.)
