Embodiment
A kind of production method containing the solid agent of sustained release highly effective pesticide, this method are containing efficient using absorbent particles absorption
The liquor of agricultural chemicals is formed containing the solid agent of sustained release highly effective pesticide, is comprised the following steps：
Absorbent particles are carried out dewatered drying processing by step A., to absorbent particles water content below 5%；
Step B. quantitatively delivers to the absorbent particles after dewatered drying in reactor, carries out application of vacuum to reactor, and hold
It is continuous that absorbent particles are seethed；
Adsorption saturation degree of the step C. according to absorbent particles total amount in step B, take the liquor containing highly effective pesticide of corresponding amount
Liquor atomization process is carried out, the highly effective pesticide after atomization process is delivered in the reactor containing absorbent particles, ensures atomization
After highly effective pesticide after processing fully enters reactor, the pressure in reactor is equal to or less than reactor safe pressure, continuously
The absorbent particles for seething state adsorb to the highly effective pesticide of spray pattern；
After the step C of certain time is adsorbed, absorbent particles are discharged step D. in a kettle, and efficient agriculture is sustained into containing
The solid agent of medicine.
Above-mentioned technique in the embodiment of the present invention, first absorbent particles are heated to 60-75 DEG C of progress dewater treatment, is made
Absorbent particles water content is less than 5%.To absorbent particles dewater treatment, and adsorbed under vacuum conditions, absorption can be excluded
Space in the absorbent particles that agent absorption air ties up, and then it is obviously improved the suction that absorbent particles adsorb effective medicine component
Attached ratio（Improve the saturation adsorption rate of adsorbent）And adsorption efficiency.Generally absorbent particles are inhaled in natural environment
Moisture in attached air, the saturation degree when adsorbing agricultural chemicals can be reduced, after dewater treatment is carried out to absorbent particles, such as used
60 DEG C -75 DEG C of temperature discharges the water of original absorption in absorbent particles to absorbent particles heat drying in vacuum environment
When dividing with air, the ratio that absorbent particles adsorb effective medicine component can be lifted, the present invention contains acticarbon particle
Water 15% falls below less than 5% from national standard, absorbent particles saturation degree when adsorbing liquor is improved more than 10%,
Improve the adsorption rate more than 10% of absorbent particles absorption effective agent.The negative pressure state of starting is until complete to be adsorbed to reaction
The safe pressure of kettle, production process is safer, efficient, solves high pressure risk of explosion.
In embodiments of the present invention, to realize that absorbent particles adsorb the absorption to two or more agricultural chemicals, chloropicrin is overcome
The defects of liquor and metham-sodium liquor are unable to compounding use, realize in solid agent and contain chloropicrin agricultural chemicals and metham-sodium agricultural chemicals, realize
Two kinds of composite reagents use.The process of use is：In step C, the absorption according to absorbent particles total amount in step B is satisfied
And degree, in the ratio containing metham-sodium and chloropicrin agricultural chemicals in the solid agent of sustained release highly effective pesticide, take corresponding amount contains metham-sodium agriculture
Medicine and liquor containing chloropicrin agricultural chemicals carry out liquor atomization process respectively, by the metham-sodium agricultural chemicals after atomization process deliver to containing
In the reactor of absorbent particles, after ensureing that the metham-sodium agricultural chemicals after atomization process fully enters reactor, the pressure in reactor
Power is equal to or less than reactor safe pressure, and the absorbent particles for continuously seething state are carried out to the metham-sodium agricultural chemicals of spray pattern
Absorption, after absorbent particles complete the absorption of metham-sodium agricultural chemicals, the chloropicrin agricultural chemicals after atomization process is delivered to containing adsorbent
Grain reactor in, ensure atomization process after chloropicrin agricultural chemicals fully enter reactor after, the pressure in reactor be equal to or
Less than reactor safe pressure, the absorbent particles for continuously seething state adsorb to the chloropicrin agricultural chemicals of spray pattern.
Using being that metham-sodium agricultural chemicals is adsorbed first, its reason is that the boiling point of metham-sodium is 218 °C of physical property
Determine, absorbent particles adsorb to the metham-sodium agricultural chemicals of spray pattern at high temperature, and metham-sodium agricultural chemicals carries out absorption completion
Afterwards, adsorb chloropicrin agricultural chemicals, its reason is the boiling point of chloropicrin：112 °C of physical properties determine, reduce chlorination
The environment temperature during absorption of bitter agricultural chemicals, the metham-sodium agricultural chemicals for preventing from being adsorbed are atomized and are atomized again and absorbent particles again
Separation.
The present embodiment, which solves, realizes that chloropicrin agricultural chemicals liquor can not be real with the technological deficiency of metham-sodium agricultural chemicals liquor mixture
Existing chloropicrin agricultural chemicals is lain in same adsorbent simultaneously with metham-sodium agricultural chemicals, plays the purpose that two kinds of composite reagents use.
In embodiments of the present invention, to make the liquor of atomization maintain atomization vaporized state, absorbent particles are facilitated to adsorb,
In step C, the suitable environment temperature that the absorbent particles of state are adsorbed to the highly effective pesticide of spray pattern is continuously seethed
For：95℃-135℃.
In embodiments of the present invention, to ensure that the medicament of final solid dosage forms does not influence plant growth, in step A, institute
The absorbent particles stated are activated carbon or expanded vermiculite or the mixture of activated carbon and expanded vermiculite, and described absorbent particles are inhaled
Attached ratio is 10%-55%.Activated carbon or the selection gist of expanded vermiculite and its mixture be, cost of material, saturation adsorption rate with
And the factor such as the requirement of soil to adsorbent elements.

Percentage by weight is 48%, contains metham-sodium agricultural chemicals liquor by weight into containing the solid agent of sustained release highly effective pesticide in described step D
Percentage is 53%-55%.Meet that metham-sodium active compound content is 25% in the solid agent of activated carbon, has containing the solid agent of sustained release highly effective pesticide
Slow-release pesticidal, sterilization functions.
Domestic existing metham-sodium liquor active compound content is 35%-48% liquors, is further added by content and crystalline solid, chloropicrin then occurs
Active compound component content more a height of 99.8% in liquor, produce solid agent and be easier to, be 25%-30% contents, but production metham-sodium is then not
Easily, because composition containing active compound is low, highest only has 48%（Active compound accounts for liquor percentage by weight）, based on adsorption rate 53%, then 48% ×
53%=25.44%（Metham-sodium active compound accounts for the percentage of solid agent gross weight）, and in the company standard for using and formulating in practice
It is required that active compound content is 25%（Metham-sodium active compound accounts for the percentage of solid agent gross weight）, mu apply 13-14 kilograms, soil could be met
Earth sterilization, desinsection, the effect of sterilization, in practice it has proved that when best acticarbon handling process is proper, highest adsorption rate
For 55%.So the adsorption rate of activated carbon, is brought up to 55% and above is important elder generation by the solid agent of the activated carbon for wanting manufacture metham-sodium
Certainly condition, the present invention solve the problems, such as adsorption rate, allow manufacture to play the role of actual soil disinfection, desinsection, the metham-sodium of sterilization
