1. I-sodium naphthalene sulfonate formaldehyde FDN ikwabizwa ngokuba yi-naphthalene esekelwe kwi-superplasticizer, i-poly naphthalene sulfonate, i-sulphonated naphthalene formaldehyde. Imbonakalo yayo ngumgubo omdaka okhanyayo. I-superplasticizer ye-SNF yenziwe nge-naphthalene, i-asidi ye-sulfuric, i-formaldehyde kunye nesiseko se-liquid, kwaye ifumana uluhlu lweempendulo ezifana ne-sulfonation, i-hydrolysis, i-condensation kunye ne-neutralization, kwaye yomiswa ibe ngumgubo.
2. I-Naphthalene sulfonate formaldehyde ngokuqhelekileyo ibizwa ngokuba yi-superplasticizer yekhonkrithi, ngoko ke ilungele ukulungiswa kwekhonkrithi ephezulu yamandla, ikhonkrithi ene-steam-cured, ikhonkrithi yolwelo, ikhonkrithi engangeni manzi, ikhonkrithi yeplastiki, imivalo yentsimbi kunye ne-prestressed. ikhonkrithi eyomeleziweyo. Ukongeza, i-sodium naphthalene sulfonate formaldehyde ingasetyenziselwa njenge-dispersant kwimizi-mveliso yesikhumba, ye-textile kunye nedayi, njl.njl Njengomenzi oyingcali we-naphthalene superplasticizer e-China, i-Longou ihlala ibonelela ngekhwalithi ephezulu ye-SNF powder kunye namaxabiso efektri kubo bonke abathengi.
