Lignosulfonate is used as a water treatment agent
Sodium Lignonsulphonate:
Sodium lignosulfonate (sodium salt of lignosulfonic acid) is a natural polymer and anionic surfactant. Its appearance is brown powder or liquid, no special odor, non-toxic, easily soluble in water and lye, precipitated by acid, and has strong dispersing ability. As a kind of surfactant, sodium lignosulphonate can produce multiple products through modification, processing, compounding and other methods, mainly used in concrete, cement, resin, rubber, dye, pesticide, ceramics, asphalt, feed, water treatment , coal water slurry, refractories, oil field drilling, compound fertilizers, smelting, casting, adhesives.

Use of sodium lignosulfonate:
Its structural unit contains phenolic hydroxyl and carboxyl groups, which can generate insoluble protein complexes, which are used to control suspended matter and iron scale, and have dispersion ability. It is a dispersing and integrating agent, and also a sustained release agent.
In the circulating water treatment agent, the use of this product and zinc complexation, so that the zinc in the water can be stored, in order to continuously provide a certain amount of zinc ions, inhibit the corrosion of the water system, with it and polyol phosphate and zinc compound agent. When used as a dispersion scale inhibitor in boiler water, it has good thermal stability and maintains good dispersion performance even at 250° C. It is also effective in dispersing aqueous oxides and organic dirt in water. Sodium lignosulfonate has dispersion, bonding, complexation and emulsification. Stabilizing effect, can be widely used in various industries. However, its biggest disadvantage is that its composition is unstable, its performance often fluctuates, and it is easy to decompose under high temperature and high pressure, which is very unfavorable to modern water treatment. However, due to its advantages of convenient source, low price and no pollution, it is still used in a small amount in the composite formulation of circulating cooling water treatment agent.
Packaging and storage
1. Powder products are made of chemical fiber woven bags, lined with plastic film bags, each bag net weight (40±0.2kg) or (25±0.2kg) or (750±0.2kg), can also be customized according to customer requirements.
2. Powder products should be stored in dry and ventilated special warehouse, products such as damp caking can be crushed or dissolved into water agent use does not affect the actual effect.
