Lignosulfonate is used in the processing of dry suspension agent
Lignosulphonates (Lignosulphonates) is a kind of paper waste liquid containing lignin as raw material for sulfonation processing, and then through condensation, conversion, desugar and other reactions to prepare an important product specially applied in the chemical market. Choose lignosulfonate, many people do not know how to identify and detect, the following first introduce lignin.
Lignin is naturally present in wood. The biosynthesis of lignin, in brief, consists of carbon dioxide and water through photosynthesis through D-glucose, shikimic acid, tyrosine, p-hydroxycinnamic acid, coumarol to pinol and butanol, and finally consists of three compound units of pinol, pinol and butanol. By dehydrogenation polymerization, lignin, which is a kind of amorphous phenolic polymer with a very complex structure, is produced.
Wood (the main raw material of the cellulose industry) is mainly composed of three chemical compounds (cellulose, hemicellulose and lignin); Its composition, cellulose accounted for more than 50%, hemicellulose about 10%, lignin accounted for more than 30%. Lignin, considered the most valuable and resource-rich natural polymer on Earth, is produced by dehydrogenation polymerization of the three different types of phenylpropyl monomers mentioned above (coumarin, sumberol, and butanol).
For many years, lignesulfonates have been widely used as dispersing agents in pesticide powders, wettable powders, suspensions, water-dispersing granules and micro-capsule suspensions. It is especially used in wettable powder and water dispersible granule.

Lignosulfonate has the following outstanding advantages:
① It has good compatibility with all kinds of pesticide active ingredients.
② There is good dispersion in the processing, and sometimes there is a certain wettability.
③ Green environmental protection, can be biodegradable in nature.
④ Rich resources, low price.
⑤ Not only has a good dispersion effect, but also has the effect of anti-precipitation and protection of colloids.
⑥ Can play a chelating agent with metal ions.
⑦ Can enhance the hard water resistance of the suspension agent.
⑧ Has good heat resistance, which is fully applied in the processing of dry suspension agent.ent.
