Concrete Admixture Sodium LignosulfonateProduct IntroductionThe sodium lignosulfonate, which is prepared from alkaline
pulping black liquor through filtration, sulfonation, concentration and spray drying, and is a powdery low air-entrained set retarding and water reducing admixture, belongs to an anionic surface active substance, has absorption and dispersion effect on the cement, and can improve various physical properties of the concrete.
Application1. Can be used as a
water-reducing admixture for concrete, and applicable for projects such as culverts, dikes, reservoirs, airports, expressways and so on.
2. Used as a
scale remover and a circulating water quality stabilizer on boilers.
3. Sand
preventing and sand fixing agents4. Used for
electroplating and electrolysis, and can ensure that the coatings are uniform and have no tree-like patterns.
5. Used as a tanning auxiliary in
leather industry.6. Used as a flotation agent for ore dressing and an adhesive for
mineral powder smelting.7.
Coal water slurry additive8. Long-acting slow-release nitrogen
fertilizer agent, a modified additive for high-efficiency slow-release compound fertilizers
9. Used as a filler and a dispersant for
vat dyes and disperse dyes, a diluent for acid dyes and so on.
10. Used for anodal anti-contraction agents of lead-acid storage batteries and alkaline
storage batteries, and can improve the low-temperature urgent discharge and service life of the batteries.
