Lignosulfonate is an excellent green dispersant HS 3804000090

Because lignosulfonate contains phenolic hydroxyl group, alcohol hydroxyl group, carboxyl group, sulfonic group and other functional groups, in aqueous solution, lignosulfonate has strong lyophilic and electronegative property, and can form anionic groups. After the lignosulfonate anionic groups are adsorbed to the particles, the mixture is more stable due to electrostatic repulsion. The electrostatic repulsion of lignosulfonate anion groups and the lubrication of micro-bubbles produce the adsorption and dispersion effect of lignosulfonate, and the lubrication of micro-bubbles plays the main role.

Lignosulfonate is an excellent dispersant and wetting agent in pesticides. Its own main raw materials are separated from plants and extracted, and are not used for crops, which are not available to other chemical dispersants. Lignosulfonate is used in wettable powder and can be quickly dissolved in water to form a stable suspension. In the spray application process, due to the strong dispersing effect of lignosulfonate, the agent is evenly dispersed in the fog drop. The droplet falls on the leaf stem of the plant. Due to the surface activity and film formation of lignosulfonate, it can achieve a large area coverage and achieve a wide and uniform application effect.

Lignin pesticide dispersant is a kind of lignin pesticide dispersant which is prepared by chemical modification and refined processing of waste liquor from pine pulping by sulfite process. The product can be used as a suspension agent, filler and dispersant in the wettable powder of pesticide processing, with good heat storage performance, excellent suspension performance and good wettability.

Effect of lignosulfonate powder on the properties of dosage form products :

The sulfonation degree, molecular weight and salt content of lignosulfonate will directly affect the performance of the dosage form products.

Effect of increasing sulfonation degree of Lignosulfonate powder :

① The dissolution rate in water and fertilizer solution increases;

② Shear viscosity will decrease;

③ The dispersion stability is improved at low temperature, high ionic strength and low pH.

Effect of increasing molecular weight of lignosulfonate powder:

① Suspension performance increased;

② The shear viscosity increases;

③ The dissolution rate decreases;

④ The dispersion stability is improved at high temperature, low ionic strength and high pH.

Effect of increasing salt content of lignosulfonate powder :

① Increased shear viscosity;

② Heat storage stability increased;

③ Suspension performance increased;

④ Dissolution rate increased.
