Sodium lignin sulfonate

Описание

Sodium lignin sulfonate is mainly compose for lignin, sulfonate and other additives. Lignin is the main component, and its content is generally above 50%. It is a natural polymer compound, mainly composed of phenylpropane structural units, with a variety of functional groups, such as hydroxyl, methoxy, carboxyl, etc. Sulfonate is another important component of sodium lignin sulfonate, which is compose for sulfonate ions and sodium ions, and has good water solubility and interfacial activity. C20H24Na2O10S2 has many applications in the manufacture of refractory materials.
First, sodium lignin sulfonate can be used as a dispersant and adhesive. When making refractory bricks and tiles, adding sodium lignin sulfonate can significantly improve the operating performance, and has good effects such as water reduction, strengthening, and preventing cracking. It can make the particles in the refractory material better dispersed, improve the uniformity and density of the material, and thus improve the overall performance of the refractory material.
Secondly, the addition of C20H24Na2O10S2 can also improve the strength and durability of the refractory material. By increasing the tensile and compressive strength of refractory materials, improving the shear and impact strength, the finished refractory materials produced have a smooth surface, complete edges and corners, significantly reduced cracks in the bricks, and are strong and durable. In addition, C20H24Na2O10S2 can also use for a grinding aid for refractory materials to increase the strength of wet billets and shorten the drying time, thereby improving production efficiency. At the same time, it can also reduce production costs and improve economic benefits.
