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 construction industry. Because this product not only has a strong dispersing effect on cement particles, but also has a higher water reduction rate. In addition, SNF is also highly utilized in various industries such as agriculture, plastics and rubber, papermaking, textiles and petroleum, etc.
Naphthalene series superplasticizer (naphthalenesulfonic acid formaldehyde condensate) and some other chemical admixtures play an important role in modern concrete materials and technologies, which can improve various properties of concrete and promote the development of new concrete technologies. When used with mineral admixtures at the same time, sodium naphthalene formaldehyde can promote the utilization of industrial by-products (such as ground slag and fly ash, etc.) in the cementitious material system, which helps to save resources and protect the environment. With the continuous search for more low-cost, environmentally compatible materials and technologies, it is expected that naphthalene superplasticizer will play an important role in future concrete production.
Sodium naphthalene sulfonate (SNF) is a light yellow to yellow-brown powder, and it is easily soluble in water, ethylene glycol, diethylene glycol, slightly soluble in alcohols, and insoluble in organic solvents. In construction industry, sodium naphthalene sulphonate is widely used to prepare free-flowing and pumpable concrete mixtures. As a leading manufacturer of construction chemicals in China, Kingsun naphthalene sulfonate powder for sale has three types, they are SNF-A, SNF-B, SNF-C. And they all have different technical specifications (as shown in the table below).
