The concept of dispersant is present in the formulation of imported pesticide additives. It is considered from the synthesis process of polycarboxylates. A product is relatively concentrated in molecular weight distribution, and it is difficult to target the range of all materials. To solve this problem, the general imported products have matching dispersing agents. Domestic pesticide additives are mostly selected from NN0 and sodium polyphosphate. NNO disperses and suspends well on some products, but the addition is excessive, easy to absorb moisture and make the particles become sticky; sodium polyphosphate has obvious effect on improving the suspension rate performance, but its industrial grade and analytical grade are quite different, no Conducive to unified procurement, and excessive addition, it is easy to harden the particles, which is not conducive to disintegration. Moreover, the thermal storage properties of these two additives are not ideal.
