Calcium Lignosulphonate is used as a pesticide diapersion sustained release agent
Calcium Lignosulphonate:
Lignin can not only be used as a dispersant of dyes, but also as a dispersant of pesticides. Its advantages are:
(1) Lignin is larger than the surface, lighter, and can be fully mixed with pesticides. In particular, there are many active bases in the molecular structure, and it can chemically combine with pesticide molecules through simple chemical reactions.
(2) Lignin has a good ability to absorb ultraviolet light, and can play a stable role in photosensitive and oxygen-sensitive pesticides;
(3) Lignin can degrade slowly in soil, and there will be no residue of pollutants.
(4) Lignin itself is non-toxic.
Generally speaking, for pesticides with strong hydrophobicity, lignosulfonate dispersions with higher relative molecular weight and lower degree of sulfonation are needed. In a certain range, the larger relative molecular weight of sulfonate is, the narrower molecular weight distribution is, the lower degree of sulfonation is, and the better its dispersion performance is. Through the selection of process conditions, changing the relative molecular weight and sulfonation degree of lignosulfonate can selectively improve some properties, so that lignosulfonate products can be mixed with many agricultural products, widely used as a dispersant of wetability powder, water dispersion granule, suspension agent.
Due to the low toxicity of lignosulfonate series products, natural degradation, degradation products are almost non-toxic, and the price is lower than other dispersants, so that its use in the weatable powder occupies the first place. Calcium lignosulfonate is widely used.
