Lignosulfonate is used in the processing of pesticide dosage forms
Dispersant is a surfactant that can prevent flocculation between particles, play a dispersive role, and stabilize particles. Dispersant is indispensable in the processing of pesticide dosage form products, and its use prevents the dispersed pesticide particles from flocculating, aggregating or coalescing. At the same time, it can ensure that these products have a high suspension rate after diluting with water when applied, so as to improve the drug products have a high efficacy.
Lignosulfonates (such as sodium lignosulfonate, calcium lignosulfonate and ammonium lignosulfonate) dispersants are anionic surfactants. There has been a close relationship between lignosulfonate powder and pesticide dosage form products for a long time, and its application can be seen in processing powder, wettable powder, suspension agent, water dispersion granule and other products. Especially in the processing of wettable powder and water dispersion granule, the selection of lignosulfonate plays a very effective dispersion effect, and as the research object of effective dispersion effect. Because lignosulfonate dispersant not only has excellent dispersion effect, but also can biodegrade, it is a kind of green dispersing agent product. It also takes into account that it has incalculable resource advantages, relatively cheap prices, especially in the processing of pesticides is very popular, and has broad application prospects.

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.
