Description
Technical field
The invention belongs to formulations of pesticide field, be specifically related to a kind of weed killer herbicide, bactericide, agrochemical pesticide dry suspending agent formulation manufacture method.
Background technology
Missible oil, pulvis, wetting powder, granule four major types are occupied an leading position on the formulations of pesticide at present, and wherein the missible oil formulation accounts for half of agricultural chemicals total amount.Farm chemical emulsion preparation not only expends a large amount of organic solvents, and serious environment pollution.Therefore, use no or little organic solvent in recent years aborning, the novel form good with Environmental compatibility obtains exploitation as far as possible.At present, the novel form development trend just towards water-based, granular, slowly-releasing, multi-functional, laborsaving, become more meticulous and the direction of high concentrationization develops, some are efficient, safety, economy, labour-saving formulation are risen.
Dry suspending agent is the novel form that grows up on the basis of wetting powder and suspending agent.It has lot of advantages: (1) does not neither with an organic solvent produce dust again, and is all fool proof to operator and environment, and this is the main cause of being favored and developing rapidly in the U.S., this formulation of Europe.(2) compare with suspending agent with wetting powder, the active constituent content height is given packing, stores, is transported and brought very big economic benefit and social benefit.(3) physical and chemical stability is good, is difficult for decomposing rotten.(4) available papery packing is convenient to reclaim and is destroyed or natural degradation.(5) good fluidity, easily metering, not sticking wall can not remain in and form secondary pollution in the packing container.(6) medicine grain diameter is superfine, helps target and fully absorbs and play a role, and can improve the pesticide original medicine service efficiency, reduces consumption, improves effect.
The granulation mode of dry suspending agent mainly contains spray granulation.The shortcoming of spray granulation is the wet granulation mode, preparation to be made aqueous suspension agent earlier, the spray-dried again product that obtains, the whole former medicine instability of production process, energy consumption height and particle are little and loose, general its particle diameter is 0.1-0.3cm, and bulk density is at 0.2-0.5g/cm.
Summary of the invention
The objective of the invention is to overcome the shortcoming in the granulation mode process of spray granulation, propose that a kind of technology is simple, equipment investment is few, the particle of gained circle and evenly, be convenient to the non-slurry pelletizing mode of the pesticide dry suspending agent of penetration and promotion, general particle diameter can reach 0.3～1.5cm, and bulk density can reach 0.5～0.8g/cm.
Purpose of the present invention can reach by following measure:
A kind of prilling process of pesticide dry suspending agent, pesticide original medicine is mixed the back just be ground into 150～250 purpose powder with solid additive, pass through rigidity comminution by gas stream and flexible comminution by gas stream again, obtain female powder of 5～10 μ m, with female powder with contain granulation after the aqueous solution of binding agent, oven dry, screening, obtain the pesticide dry suspending agent that diameter is 0.3～1.5cm
Wherein just pulverize and adopt hammer mill to pulverize, flexible comminution by gas stream adopts flat airslide disintegrating mill (as rotating disc type) to pulverize, and the rigidity comminution by gas stream adopts the fluidized bed type airslide disintegrating mill to pulverize.
The present invention adopts three grades of pulverizing process in pulverizing process, earlier be ground into 150-250 purpose powder through hammer mill, be ground into 600-800 purpose powder through flat airslide disintegrating mill again, after the fluidized bed type airslide disintegrating mill is pulverized, get ultra-fine female powder of 5-10 μ m again.The feeding air pressure of wherein flat airslide disintegrating mill and fluidized bed type airslide disintegrating mill is 0.3～0.9MPa, and the pulverizing air pressure is 0.6～1.5Mpa, and charging rate is 15～130kg/h.
During granulation female powder sent into through the vacuum dispenser and carry out granulation in the fluidized granulating machine, spray into the aqueous solution that contains binding agent simultaneously.The feeding speed of granulation is 10～130kg/h, and atomisation pressure is 0.1～0.3Mpa.The consumption that contains the aqueous solution of binding agent is 20～100% of female grain weight amount.Wherein binding agent is sodium carboxymethylcellulose, Ac-Di-Sol, polyoxyethylene alcohol, gum Arabic or a Macrogol 2000-6000.
Concrete grammar of the present invention is: with pesticide original medicine and solid additive (i.e. wetting agent except that binding agent and water, dispersant, disintegrant, filler) mixes, be ground into 150-250 purpose powder through hammer mill, be ground into 600-800 purpose powder through flat airslide disintegrating mill again, after pulverizing, the fluidized bed type airslide disintegrating mill gets ultra-fine female powder of 5-10 μ m again, the feeding air pressure of airslide disintegrating mill is 0.3-0.9Mpa, the best is 0.8Mpa, the pulverizing air pressure is 0.6-1.5Mpa, the best is 1.2Mpa, charging rate is 15～130kg/h, and the best is 45～50kg/h.Female powder is sent in the fluidized granulating machine through the vacuum dispenser; spray into the aqueous solution that contains suitable on a small quantity binding agent simultaneously; can carry out fluidized granulating, the feeding speed of granulating working procedure is 10～130kg/h, and the best is 45～50kg/h; atomisation pressure is 0.1-0.3Mpa; the best is 0.15Mpa, and oven dry obtains even pesticide dry suspending agent of the present invention through screening more simultaneously; particle diameter can obtain the particle of different size according to mesh size, and diameter is 0.3-1.5cm.Particle good dispersion, uniform particles, the density produced with this technology are suitable.
