Abstract
The invention discloses a preparation method of tebuconazole suspension concentrates used for preventing crop rust, powdery mildew, net blotch, foul foot and gibberella zeaze petch of wheat and barley, groundnut early leaf spot, exobasidium vexans massee of tea plants, and bunt smut. The preparation method comprises the following steps of dispensing, emulsifying, sanding, mixing, secondary-dispensing, stirring, canning and the like, wherein all components are prepared at the first dispensing according to a certain weight. The invention prevents products from layering, degrading and agglomerating, and has the advantages of good product stability, good use effect, low production cost, high drug effect, and good economic benefit.
Description
Technical field
The present invention relates to a kind of preparation method of agricultural chemicals, relate in particular to a kind of preparation method who is used for preventing and treating the tebuconazole suspension concentrates of crops rust, powdery mildew, net blotch, root rot and gibberella zeaze petch of wheat and barley, the cercospora brown spot of peanut, tea tree tea gall, stinking smut.
Background technology
It is not really stable later on that tebuconazole suspension concentrates is processed into product, all is mostly phenomenons such as layering, caking and content degraded to occur in half a year, do not have effect when causing product to use even can't use, so the selection to auxiliary agent is extremely important in this formula for a product.We are through repeatedly debugging and developing, and invented a kind of prescription of producing the 430g/l tebuconazole suspension concentrates through Success in Experiment repeatedly, the invention of this prescription is by selecting proper assistant, overcome phenomenons such as this product layering, caking and content degraded, make product stable, result of use is good, and the product cost of producing with this prescription is low, the drug effect height, this prescription is put into after the society, can bring very high income to society.
Summary of the invention
At the deficiencies in the prior art, the invention provides and a kind ofly can overcome product layering, caking and content signs of degradation, product stability is good, result of use is good, and production cost is low, the drug effect height, the preparation method of the tebuconazole suspension concentrates of big control crops rust, powdery mildew, net blotch, root rot and the gibberella zeaze petch of wheat and barley of community income, the cercospora brown spot of peanut, tea tree tea gall, stinking smut.
For solving the problems of the technologies described above, the invention provides a kind of preparation method of tebuconazole suspension concentrates, described preparation method comprises following processing step:
Step 1: prepare burden for the first time, former medicine of Tebuconazole and auxiliary agent are put in the emulsion tank by the proper proportion proportioning, stir the material that basic evenly back formation mixes with wooden stick;
Step 2: open high-speed mixer, above-mentioned material is carried out emulsification in emulsion tank;
Step 3: the material after the emulsification enters 2 company's of scurrying formula sand mills successively and carries out sand milling, and wherein first sand mill sand milling time is no less than 2 hours, and second sand mill sand milling time is no less than 2 hours;
Step 4: after sand milling finished, with 50kg running water cleaning equipment and ducted clout, then that sand milling is good material was imported in the preassigned head tank and is mixed;
Step 5: in head tank, add water 80kg, open the agitator in the head tank, stirred 20 minutes～30 minutes;
Step 6: batching for the second time, treat lather collapse after, the mixed solution of going back virgin rubber and 20kg ethylene glycol of getting 2.5kg slowly adds in the material;
Step 7: stir control in the sampling after 20 minutes, treat to add water again according to analysis result after the result comes out, be generally and add water 67.5kg, canned back forms finished product.Every crowd of finished product 1085kg.
Wherein, each component of Tebuconazole material is pressed following weight proportion in described step 1:
The former medicine of 95% Tebuconazole: 453.0kg
NP-100：4.0kg
Turn round and look at 2700:10.0kg
7204:6.0kg is changed very much in Nanjing
Sodium Benzoate: 2.0kg
Ethylene glycol: 30kg
Clean tap water: 360kg
Because adopt above-mentioned technical scheme, the present invention has following beneficial effect:
Prevent product layering, caking and content signs of degradation, good product stability, result of use is good, and production cost is low, drug effect height, economic benefit height.
Description of drawings
Fig. 1 is the preparation method's of tebuconazole suspension concentrates of the present invention process chart.
Embodiment
As shown in Figure 1, the invention provides a kind of preparation method of tebuconazole suspension concentrates, described preparation method comprises following processing step:
Step 1: prepare burden for the first time, former medicine of Tebuconazole and auxiliary agent are put in the emulsion tank by the proper proportion proportioning, stir the material that basic evenly back formation mixes with wooden stick;
Step 2: open high-speed mixer, above-mentioned material is carried out emulsification in emulsion tank;
Step 3: the material after the emulsification enters 2 company's of scurrying formula sand mills successively and carries out sand milling, and wherein first sand mill sand milling time is no less than 2 hours, and second sand mill sand milling time is no less than 2 hours;
Step 4: after sand milling finished, with 50kg running water cleaning equipment and ducted clout, then that sand milling is good material was imported in the preassigned head tank and is mixed;
Step 5: in head tank, add water 80kg, open the agitator in the head tank, stirred 20 minutes～30 minutes;
Step 6: batching for the second time, treat lather collapse after, the mixed solution of going back virgin rubber and 20kg ethylene glycol of getting 2.5kg slowly adds in the material;
Step 7: stir control in the sampling after 20 minutes, treat to add water again according to analysis result after the result comes out, be generally and add water 67.5kg, canned back forms finished product.Every crowd of finished product 1085kg.
The present invention overcomes phenomenons such as this product layering, degraded, caking by selecting proper assistant, makes product stable, result of use is good, and the product cost of producing with this prescription is low, the drug effect height, product is put into after the society, has very high social benefit and economic benefit.
