Product Description
Sodium ligninsulfonate is a kind of natural polymer and anionic surfactant. It has a strong dispersion ability and is suitable for dispersing solids in water medium.
Sodium Lignin sulfonate is a brown yellow powdery substance in appearance and gives off slight aroma, with the molecular weight of 800 to 1,000 usually and strong dispersibility, cohesiveness and chelating property. concrete water reducer are mainly for concrete mixture as water-reducing additive. Low dosage, low air content, water reducing rate is high,adapt to most kind of cement. Can confected as concrete early-age strength enhancer, concrete retarder, antifreeze, pumping aids etc. Nearly no precipitate product in the liquor additive which is made from The sodium lignosulphonate and Naphthalin-Group High-Efficiency Water Reducer.
Application
Sodium lignosulfonate is mainly used in resin, rubber, dyes, pesticides, ceramics, cement, asphalt, feed, water treatment, coal water slurry, concrete, refractory materials, oilfield drilling, composite fertilizer, smelting, casting, adhesives.
The main properties are:
1.Concrete superplasticizer: a powdery low permeability retarding setting superplasticizer. Improve the workability of concrete, and can greatly reduce the initial hydration heat of cement hydration, can be mixed into early strength agent, retarder, antifreeze, pumping agent, etc. The liquid admixture made with naphthalene series high efficiency water reducing agent has basically no precipitation.
2.Coal water slurry additive;
3.Refractory and ceramic body reinforcing agent;
4.Fillers and dispersants for dye industry and pesticide processing;
5.As a binder for powder and granular materials;
6.Used as diluent dispersant and viscosity reducer in drilling;
