1. Sodium naphthalene sulfonate formaldehyde FDN nayo yitwa naphthalene ishingiye kuri superplasticizer, poly naphthalene sulfonate, sulfonated naphthalene formaldehyde. Isura yacyo ni ifu yijimye yijimye. SNF superplasticizer ikozwe muri naphthalene, aside sulfurike, formaldehyde na base yamazi, kandi ikagira ingaruka zitandukanye nka sulfonation, hydrolysis, kondegene no kutabogama, hanyuma ikuma mu ifu.
2. beto. Byongeye kandi, sodium naphthalene sulfonate formaldehyde irashobora kandi gukoreshwa nkikwirakwiza mu nganda z’uruhu, imyenda n’irangi, nibindi nkumushinga wumwuga wa naphthalene superplasticizer mubushinwa, Longou burigihe itanga ifu nziza ya SNF nibiciro byuruganda kubakiriya bose.
