Sodium naphthalene sulfonate formaldehyde (referred to as SNF A/PNS/FND/NSF) is alternatively known as naphthalene-based superplasticizer, sodium polynaphthalenesulfonate, and sulphonated naphthalene formaldehyde. It presents itself in the form of a light brown powder. The manufacturing process for SNF high-efficiency water reducer entails using naphthalene as the primary raw material, followed by a sequence of reactions involving sulfuric acid, formaldehyde, liquid alkali, sulfonation, hydrolysis, condensation, and neutralization, ultimately resulting in the production of powdered SNF.
