1. Sodium naphthalene sulfonate formaldehyde FDN imatchedwanso naphthalene based superplasticizer, poly naphthalene sulfonate, sulphonated naphthalene formaldehyde. Maonekedwe ake ndi ufa wonyezimira. SNF superplasticizer imapangidwa ndi naphthalene, sulfuric acid, formaldehyde ndi madzi oyambira, ndipo imachita zinthu zingapo monga sulfonation, hydrolysis, condensation ndi neutralization, kenako zowuma kukhala ufa.
2. Naphthalene sulfonate formaldehyde ambiri amatchedwa superplasticizer kwa konkire, choncho makamaka oyenera prepatation wa mkulu-mphamvu konkire, nthunzi-anachiritsa konkire, madzi konkire, impermeable konkire, madzi konkire, plasticized konkire, mipiringidzo zitsulo ndi prestressed. konkire yowonjezera. Kuonjezera apo, sodium naphthalene sulfonate formaldehyde ingagwiritsidwenso ntchito ngati dispersant mu mafakitale a zikopa, nsalu ndi utoto, etc. Monga katswiri wopanga naphthalene superplasticizer ku China, Longou nthawi zonse amapereka ufa wapamwamba wa SNF ndi mitengo ya fakitale kwa makasitomala onse.
