Sodium Lignosulphonate, Sodium Naphthalene Sulphonate and Calcium Lignosulphanate

Antifoaming Agent

Sodium lignosulfonate (wood pulp) is the extract from the bamboo pulp process, which is obtained by concentration, modification, pulverization, and drying. Sodium Lignosulfonate (CAS 8061-51-6) is a light yellow (brown) free-flowing powder that is easy to dissolve in water.  The properties of the product are consistent and its long-lasting storage cannot be decomposed. Lignin series product is a kind of surfactant, a variety of products can be produced by modification, processing, and composition. The products which are produced from these things are used for raw materials. Experiments have shown that lignosulfonate is very effective in preventing sandy soils and can be used as a fixed agent for desert sand.

Many important characteristics of concrete are influenced by the ratio of water to cementitious materials used in the mix. When we lessen the amount of water in concrete, then the cement past becomes more powerful and gives long-lasting results. An increase in the quality of the paste will produce greater compressive and flexural strength, lower permeability, greater resistance to weathering, improve adhesion of concrete and reinforcement, reduce volume change due to drying and wetting, and reduce cracking tendencies.

SNF looks like yellowish or brownish powder it is widely used for the preparation of free-flowing and pumpable concrete mixes in the construction industry. SNF can be used as a raw material for an accelerator, antifreeze, and retardant compounds in various construction sectors. Its high purity characteristic makes the cement particles have high low foaming, high water reduction, and strengthening. In addition, it also improves the mobility and workability of concrete.

The structure turned out to be three aromatic alcohols: coniferyl, alcohol, p-counterpart alcohol, and sinapyl alcohol. Completely soluble in water and practically insoluble in an organic solvent.

SNF can easily be resolved glycol, diethylene glycol, glycerol. It also can be resolved in water, slightly soluble in alcohol, but insoluble in carbon-based diluents. In addition, it is widely used in various industries such as agriculture, plastics, and rubber, paper, construction, textiles, oil, and others.

Concrete has different characteristics; many important characteristics of concrete are influenced by the relationship between water and cementitious materials used in the mix. When we decrease the amount of water in the concrete the past cement becomes more powerful and gives long-lasting results. An increase in pulp quality will produce higher compressive and flexural strength, lower permeability, and higher weather ability, improve adhesion of concrete and reinforcement, reduce volume change due to drying and wetting, and reduce biases.
