Reach the international regulation to suspending agent.
It is found through experiments that, best using silicate zirconium pearl grinding effect, the first order is 2 millimeters of silicate zirconium pearls of diameter,
The second level is the 1 millimeter of silicate zirconium pearl mixing of 50% diameter, 2 millimeters of silicate zirconium pearls and diameter, and the third level is 1 millimeter of silicic acid of diameter
Salt zirconium pearl；
Cooling water temperature is one of the factor to play an important role to the grinding efficiency of sand mill, and abrasive media is in strenuous exercise's situation
Under, between machine inner wall and abrasive media under the action of impact force, frictional force, mechanical energy is converted into thermal energy, generates a large amount of
Heat, as the temperature rises, material can be aggregated, and the quality of finished particle can decline, therefore, the height of cooling water temperature
It is low to directly affect the indoor operating temperature of grinding, to influence grinding efficiency；Experiment proves that the situation identical in other conditions
Under, high by 34% using 22 DEG C of circulating water treatment amounts using the grinding efficiency ratio of 15 DEG C of chilled waters, therefore, cooling water temperature control exists
15 DEG C or so, it is greatly improved grinding efficiency.
Cyflufenamid of the present invention-kresoxim-methyl suspending agent suspending agent is compounded by cyflufenamid, kresoxim-methyl；It is a kind of high
Effect, wide spectrum, compound disinfectant both with interior suction, equivalence principle is rationally compounded according to pesticide and different compound proportions carry out biometric
Determine as a result, selection cyflufenamid and kresoxim-methyl are compounded；Cyflufenamid and kresoxim-methyl are different to the mechanism of action of fungus damage, then plus
On compounding between the two there is very high synergistic effect, therefore be a kind of ideal fungicide binary combination；Cyflufenamid
The fungicide being combined into kresoxim-methyl reaches mutual supplement with each other's advantages, improves drug effect, expands fungicidal spectrum, reduce cost, delaying drug resistance, subtract
The effect of few chemical pesticide dosage.
Above-described embodiment is merely exemplary to illustrate the principle of the present invention and its effect, and is not intended to limit the present invention.It is any ripe
The personage for knowing this technology all without departing from the spirit and scope of the present invention, carries out modifications and changes to above-described embodiment.Cause
