Abstract
The invention discloses a manufacture process of high-efficiency 40% dimethomorph WG, and relates to the technical field of chemical industry. The manufacture process comprises the steps: measuring and mixing an active compound, additives and packing according to a formula requirement to obtain a mixture I, crushing the mixture I by virtue of supermicro airflow, then sufficiently kneading the crushed mixture with a given amount of water in a kneading machine to obtain a mixture II, transferring the mixture II into an extrusion granulating machine, carrying out the granulation, and drying and screening by virtue of a screen to obtain 40% dimethomorph WG. The preparation method is simple in process and has reference significance to the research and development of a water dispersing agent.
Description
Technical field
The present invention relates to chemical technology field, be specifically related to the manufacturing process of a kind of efficient 40% dimethomorph WG.
Background technology
Water dispersible granules is a kind of pesticides new formulation grown up America and Europe phase early 1980s, is to grow up, therefore once releasing the concern being subject to agricultural chemicals company of various countries on the basis of wetting powder and suspending agent.
Water dispersible granules is the one of granule, there is the performance of granula, but be different from general granula (in water not disintegration-type), namely it can dissolve or be dispersed in water, and " water dispersible granules is made up of pesticide activity component, wetting agent, dispersant, disintegrant, binding agent and filler, particle diameter 200 1 5000nm.This formulation is applicable to the various pesticide active ingredients such as Working liquids water-soluble solid or water-fast solid, and has both had all advantages of granula, has again the performance of suspending agent polymolecularity, use conveniently, environmental pollution is little, and safety is good, added value is high, good in economic efficiency.
Compare with Traditional Agricultural pharmaceutically dosage form, WDG mainly contains following advantage:
L () does not have dust from flying, reduce the pollution to environment, to operator's safety, and can make hypertoxic kind low toxicity.
(2) compare with suspending agent with wetting powder, active constituent content is high, and mostly more than 70%, product relative density is large, and volume is little, is convenient to packaging, storage and transport.
(3) bin stability and physical and chemical stability better, particularly to agricultural chemicals unstable in water, make this formulation better than suspending agent.
(4) disintegration rate of particle is fast, and particle one touches water can be moistening immediately, and rapid disintegration in the process sunk under the water.
(5) disperse particle in a liquid only need stir tiny particulate a little can disperse in a liquid well, until liquid medicine jet is complete can keep uniformity.
Summary of the invention
Problem to be solved by this invention is to provide the manufacturing process of a kind of efficient 40% dimethomorph WG.
To achieve these goals, the technical scheme that the present invention takes is: the manufacturing process of a kind of 40% dimethomorph WG, comprises the steps:
(1) co-grinding: former medicine, auxiliary agent and filler are pressed recipe requirements metering mixing (4:1:5), recycling ultra micro air-flow crushing;
(2) mediate: utilize kneader that step (1) mixture and a certain amount of water are fully mediated;
(3) granulation: utilize Squeezinggranulator that step (2) mixture is carried out granulation, drier, sieved through sieve.
Preferably, in described step (1), the power of micro jet controls at 10-50KW.
Preferably, in described step (2), water content used is 50-60%.
Preferably, in described step (3), screen mesh is of a size of 1.7mm.
Beneficial effect of the present invention: adopt technical scheme of the present invention, by superfine communication technique, the materials such as former medicine, dispersant, disintegrant are re-dubbed powder to utilize, the preferably proportioning of each component, again by the granulation of hot extrusion granulating technique, prepare a kind of formulation advantages, environmental protection type agricultural chemical novel form with high content of technology.The water dispersible granules good product dispersibility that the present invention prepares, suspensibility is large, and wetting time is few, and disintegration time is few, and heat storage resolution ratio is little.The whole manufacture process of the present invention is workable.
Embodiment
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.
Embodiment 1:
(1) co-grinding: by former medicine, auxiliary agent and filler by formula (4:1:5) requirement metering mixing, recycling ultra micro air-flow crushing, the power of described micro jet controls at 28KW;
(2) mediate: utilize kneader that the water of step (1) mixture and mass fraction 50% is fully mediated;
(3) granulation: utilize Squeezinggranulator that step (2) mixture is carried out granulation, drier, sieved through sieve, described screen mesh is of a size of 1.7mm.
Based on above-mentioned, adopt technical scheme of the present invention, by superfine communication technique, the materials such as former medicine, dispersant, disintegrant are re-dubbed powder to utilize, the preferably proportioning of each component, again by the granulation of hot extrusion granulating technique, prepare a kind of formulation advantages, environmental protection type agricultural chemical novel form with high content of technology.The water dispersible granules good product dispersibility that the present invention prepares, suspensibility is large, and wetting time is few, and disintegration time is few, and heat storage resolution ratio is little.The whole manufacture process of the present invention is workable.
Obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
