1. Sodium naphthalene sulfonate formaldehyde FDN inonziwo naphthalene based superplasticizer, poly naphthalene sulfonate, sulphonated naphthalene formaldehyde. Chitarisiko chayo ivhu rakapfava. SNF superplasticizer inogadzirwa nenaphthalene, sulfuric acid, formaldehyde uye mvura base, uye inosangana neyakatevedzana maitiro akadai sasulfonation, hydrolysis, condensation uye neutralization, yobva yaomeswa kuita hupfu.
2. Naphthalene sulfonate formaldehyde inowanzonzi superplasticizer yekongiri, saka inonyanya kukodzera kugadzirwa kwekongiri yakasimba-yakasimba, kongiri inoputika, kongiri yemvura, kongiri isingapindi, kongiri isingapindi mvura, kongiri yepurasitiki, simbi dzesimbi uye prestressed. kongiri yakasimbiswa. Mukuwedzera, sodium naphthalene sulfonate formaldehyde inogonawo kushandiswa seyakapararira mumaindasitiri ematehwe, machira uye dhayi, nezvimwewo Senyanzvi yekugadzira naphthalene superplasticizer muChina, Longou inogara ichipa yakakwira SNF poda uye mitengo yefekitori kune vese vatengi.
