Construction Chemicals / Snf Admixture Naphthalene Superplasticizer
Naphthalene formaldehyde sulphonate is brown yellow to dark-brown powder, an anion surface active agent. Easily soluble in water, acid, alkali and hard water. It has good dispersing property and affinity with protein and polyamide.
1.SNF has no retarding and no air-introducing. It is characterized as good superplasticing performance, high water-reducing rate and high strength with low dosage. It has no chloride, low alkali contentlow sulphonate and high purity. This product is easy to use and can be widely used in differet concretes.
2.SNFcan be applied to make flowing, strong or steam-curing concrete. The minimum working temperature can be as low as zero centigrade degree. In steam curing, concrete with superplasticizer hasto be strong enough before heating. The steam curing specification ha s to be pre-tested, It is particularly used as base material for ,compound admixtures.
3.It can prevent from the alkali-aggregate reaction because of the biggish alkali reactivity of aggregate or the alkali-aggregate reaction in the moist environment.
Advantages:1.High water-reducing rate: SNF can reduce water 20-30%. It has features of superplasticizer effectively increases concrete fluidity and reduces water penetration ans segregation and improves the encapsulation forceof the concrete with reinforcing steel bar.
2.Strengthening: Given the same amount of cement and slump requirement, this product with the dosage 0.5-1.2% can increase the concrete the concrete early strength and reinforced effect by 50-100%, 40-70, 25-60% and 20-60% on day, 1,3,7, and 28 respectively.
3.High applicability: It can be used in variety of cement and is compatible with other admixtures.
4.Low sodium Sulfate content: The aqueous solution has no crystals in winter, which can avoid pipelinecongestions when being used. It is suitable for automatic working.
5.Effective durability: It can modify the structure of concrete and increase the property of anti-seepage, anti-freezing, and carbonization.
6.Easy to use: It can be added directly or used after dissolved in water, and also be used for different working condition and concrete mixer.Specification:
