Embodiment 122
[0030] Embodiment 122% pentothiastrobin · epoxiconazole suspension concentrate
[0031] The raw material formula is shown in Table 1, wherein the thickener is gum arabic, the antifreeze is propylene glycol, and the preservative is formaldehyde.
[0032] The preparation method of the suspending agent is as follows: add each raw material into the sand mill cylinder according to the formula, and after stirring evenly, pre-disperse it with a high shear machine, then transfer it to a sand mill for sand milling, add sanding medium zirconia beads, and start sanding Grinding, so that the average particle size of the material is below 3 μm, stop sanding after 5 hours, filter, remove the zirconia beads, and obtain.
[0033] The technical indicators of the obtained suspension concentrate are as follows: Suspension rate ≥ 90.0%; pH value 6.0-8.0; sieve analysis (passing through a 75 μm sieve) ≥ 98%; persistent foaming (after 1 min) ≤ 25ml; pouring property: residue after pouring ≤4.0%, r...
