2-ナフタレンスルホン 酸·ホルムアルデヒド （重酷x 23) のナトリウム 化学特性,用途語,生産方法
説明
Sodium salt of polynaphthalene sulphonic acid or sodium naphthalene sulphonate formaldehyde (SNF/PNS/FND/NSF), also known as sodium polynaphthalene sulphonate or sulphonated naphthalene formaldehyde, is commonly known as high efficient water reducing agent for concrete. SNF has strong dispersing effect on cement particles, and the water reduction rate can reach 15-25%. It is especially suitable for the preparation of high-strength concrete, steam-cured concrete, fluid concrete, impermeable concrete, waterproof concrete, plasticised concrete, reinforced and prestressed concrete. concrete, reinforced and prestressed reinforced concrete.
特性
Sodium salt of polynaphthalene sulphonic acid has excellent diffusibility and protective colloid properties, but it has no surface activity such as osmotic foaming, and has affinity for protein and polyamide fibers, but has no affinity for cotton, hemp and other fibers.
使用
Sodium salt of polynaphthalene sulphonic acid is mainly used as a dispersant in disperse dyes and vat dyes; it can also be used as a dispersant in textile printing and dyeing, wettable pesticides,electroplating additives, water treatment agents, etc.
