Abstract
The invention discloses a bromo-3-chloro-5,5-dimethyhydantoin wettable powder and a production method thereof, being used for preventing and controlling various diseases of crops. The powder is prepared from bromo-3-chloro-5,5-dimethyhydantoin powder, 5,5-dimethyhydantoin, bromanine and chloramine decomposing agent, wetting agent nekal, dispersing agent NNO, light calcium carbonate, bentonite, palygouskite and the like. The production method comprises the following steps of: drying and grinding the raw materials; and uniformly mixing by weight percent and subpackaging to obtain the powder. The bromo-3-chloro-5,5-dimethyhydantoin wettable powder is quick in water dissolving speed; indexes such as the wetting time, suspensibility, water, ph value, heat storage stability, fineness all meet the standard requirements; the powder has the efficacies of efficiently and widely killing bacteria, fungus, microbe, spores and virus and is safe and convenient to use; and the bactericidal cost of crop planting is lowered, the production process cost is also lowered, the equipment is simple to operate, no 'three wastes' are discharged, and the industrial large-scale production can be realized.
Description
Technical field the present invention relates to a kind of BCDMH wetting powder and production method thereof, is used for the control of the multiple germ of crops.
The background technology BCDMH is mainly used in swimming-pool water, cooling circulating water, wastewater treatment disinfection and the bath of going out, the disinfection that also is used for various body surfaces, nonmetal medicine equipment, aquaculture system and livestock-raising canopy, house, circle and environment also can be used for fruit freshness preserving and proportion of crop planting bactericide and uses.Use is mainly used in preventing and treating the multiple diseases such as the powdery mildews such as paddy rice, wheat, cotton, capsicum, cucumber, rust, damping off, anthracnose, banded sclerotial blight, stalk break, downy mildew as the proportion of crop planting bactericide.Compare with bactericide such as the peaceful glue of wheat cup of commonly using, triazolone, triadimefon, cyflufenamid, epoxiconazole, alkene azoles alcohol, imidazates, stability in use is good, high-efficiency broad spectrum, preferably active component is controlled in the safe concentration of requirement, release concentration is more stable, has reduced the dispensing number of times, can be in for a long time bacteriostasis, bactericidal effect is 10-20 times of common fungicide, is the bactericide of a kind of safety, environmental protection.But the pure powder of BCDMH dissolves in water slowly, affect rapid sterilization effect, as adding bromo-amine chloramines distintegrant, 5 with its preparation, 5-dimethyl hydantion, wetting agent pull open the component such as powder and make wetting powder, can improve the speed that is dissolved in the water, reach rapid sterilization effect.Improve the economic benefit of proportion of crop planting.So developing compound wetting powder of a kind of BCDMH and preparation method thereof is that people are needed.
Summary of the invention the object of the present invention is to provide the compound wetting powder of a kind of BCDMH, accelerate it and be used for decomposition rate behind the crops as disinfectant, reach and have purpose efficient and wide spectrum kill bacteria, fungi, germ, gemma and virus, the use procedure safe ready, can bring into play good bactericidal effect, reduce the proportion of crop planting cost.
Another object of the present invention provides the compound wettable powder agent and process for producing same of BCDMH.
Purpose of the present invention is achieved through the following technical solutions.
A kind of BCDMH wetting powder, be by following component after oven dry is pulverized respectively, mix by mass percentage and form:
The production method of BCDMH wetting powder:
At first with above-mentioned BCDMH powder, 5,5-dimethyl hydantion, bromo-amine chloramines distintegrant, wetting agent pull open the respectively prebake of powder, dispersant NNO, precipitated calcium carbonate, bentonite and attapulgite, moisture reaches below 0.3%, again through being crushed to the pulvis less than 30 microns; Then by each constituent mass percentage weighing, add the mixer mixing and stirring, mixing time is controlled at 40-50 minute; Material after mixing is distributed into the packing of varying number, is the compound wetting powder of BCDMH.
Described BCDMH wetting powder, be by following component after oven dry is pulverized respectively, mix by mass percentage and form:
Described BCDMH wetting powder, bromo-amine chloramines distintegrant are selected sodium carbonate, sodium bicarbonate, citric acid and tartaric acid or wherein several.
The mechanism of product configuration of the present invention: adding bromo-amine chloramines distintegrant (sodium carbonate, sodium bicarbonate, citric acid and tartaric acid) is dissolved in the water and just can reaches rapid sterilization effect.Add stabilizing agent 5, can the multiple reversal reactivation under the 5-dimethyl hydantion exists, again form stable bromide and chloride with remaining bromine and chlorine residue in the water, molten bromine amount and molten chlorine dose have been improved, remaining bromine and chlorine residue windage have been reduced, can make the crops of institute's sterilization be in for a long time bacteriostasis, improve sterilization effect, reduce the dosage of BCDMH.Add wetting agent and pull open powder, dispersant NNO, precipitated calcium carbonate, bentonite, attapulgite and be mixed with wetting powder, improved the economic benefit of proportion of crop planting
Advantage of the present invention: the indexs such as the wetting time of the compound wetting powder of BCDMH, suspensibility, moisture, ph value, hot storage stability, fineness all meet standard-required.Have the characteristics such as use efficient, stable, safety, bactericidal effect is fast, environmental pollution is little, have no side effect in the use procedure.Production cost is low, equipment operating is simple, nothing " three wastes " is discharged, and can realize industrial scale production, has significant economic benefit.
After embodiment each component raw material prebake moisture content index reaches below 0.3% and to require, be crushed to pulvis less than 30 microns with the fluidized bed opposed jet mill machine, weighing mixes respectively by mass percentage.
