Abstract
The invention discloses a preparation method of a novel anti-blocking granulated fertilizer. The preparation method is characterized by comprising the steps that a granulated fertilizer is sprayed and wrapped by sulfur emulsion, the adding quantity of the sulfur emulsion is adjusted, drying is conducted, and the novel anti-blocking granulated fertilizer is obtained, wherein the adding quantity of the sulfur emulsion is 1%-60% of the mass of the granulated fertilizer; a sulfur wrapper is formed on the surface of the novel anti-blocking granulated fertilizer, the sulfur wrapper has a compact hydrophobic structure, adhesion and agglomeration in the granulated fertilizer can be prevented. According to the preparation method of the novel anti-blocking granulated fertilizer, sulfur can be evenly distributed on the surface of the granulated fertilizer, the anti-blocking function is achieved, the potential risks of sulfur are reduced, sulfur in the product can be absorbed by plants easily, and environmental protection is achieved.
Description
Technical field
The present invention relates to the preparation method of a kind of novel anti-caking granulated fertilizer, belong to novel anti-caking agent technical field.
Background technology
Fertilizer caking is the problem that chemical fertilizer industry is devoted to solve for a long time, and fertilizer caking has had a strong impact on fertilizer efficiency, and
Give storage, transport and use brings many difficulties.Traditional chemical fertilizer anti-caking agent is divided into powder body anti-caking agent and mastic to prevent by outward appearance
Agglomeration agent, but both anti-caking agent in use need to be applied in combination, and need different anti-cakings for different fertilizer
Agent and different consumptions.For environment, maximum problem is to be degraded completely.
Sulfur is one of required nutrient of crop, constitutes sulfur-containing amino acid and the basic nutrition element of protein.It is again
Can synthesize the physiological activities such as other important bioactive substances, the activation of participation enzyme, therefore, sulfur can regulate plant metabolism, carries
High yield and improvement crop product quality.A lack of sulfur not only inhibits crop yield, and reduces the quality of product, thus impact
To the mankind and the health of domestic animal.
Summary of the invention
It is an object of the invention to provide the preparation method of a kind of novel anti-caking granulated fertilizer, fertilizer surface in the present invention
Sulfur integument is hydrophobic structure, can prevent adhesion caking between fertilizer, and sulfur is evenly distributed on fertilizer surface, enhances soil
Middle sulfur to the plant available form i.e. conversion of sulfate, environmental protection, increases production, improves quality, be a kind of can be absorbed by plants new
Type anti-caking agent.
The technical scheme is that
A kind of preparation method of novel anti-caking granulated fertilizer, it is characterised in that: wrap up sulfur at granulated fertilizer surface spraying
Sulphur emulsion, and 1%～60% that the addition of sulfur emulsion is granulated fertilizer quality, by regulation sulfur emulsion addition, dry
Drying novel anti-caking granulated fertilizer；This novel anti-caking granulated fertilizer surface forms sulfur integument, this sulfur integument
There is the hydrophobic structure of densification, adhesion caking between granulated fertilizer can be prevented.
Heretofore described granulated fertilizer is that granule MAP, granule Diammonium phosphate (DAP), carbamide, potassium chloride are or/and sulfur
Acid potassium.
Heretofore described granulated fertilizer is compound fertilizer
The heretofore described aqueous solution that sulfur emulsion is sulfur.
In heretofore described sulfur integument sulfur content account for sulfur parcel after fertilizer gross mass 1%～30%.
The present invention utilizes " a kind of air atomizer spray nozzle for fertilizer anti-caking agents ", the patent No.
ZL201120159830.0, sprays.
The present invention utilizes sulfur Emulsion Spraying to wrap up, and reduces the potentially danger of sulfur in sulfur-containing fertilizer production process,
Sulfur integument is fine and close hydrophobic structure, can prevent adhesion caking between fertilizer, and can be absorbed by plant, environmental protection, volume increase,
Improve quality, be a kind of novel anti-caking technology.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described, but is not limited to embodiment." one is used in present invention utilization
The air atomizer spray nozzle of fertilizer anti-caking agents ", patent No. ZL201120159830.0, spray.
Embodiment 1
In packing machine, add graininess high-class product monoammonium phosphate particle 200kg, be preheating to 85 DEG C, spray to fertilizer surface
Sulfur emulsion, through repeatedly spraying, and heats simultaneously, makes sulfur emulsion uniformly be applied to MAP surface, altogether spraying 45L lac sulfur
Liquid, wherein in sulfur emulsion, sulfur mass concentration is 50%, obtains sulfur-bearing 10.8% monoammonium phosphate particle fertilizer after being cooled to room temperature.Fertilizer
Particle surface has been wrapped one layer of fine and close sulfur anti-caking agent.
Embodiment 2
In packing machine, add graininess high-class product Diammonium phosphate (DAP) granule 200kg, be preheating to 85 DEG C, spray to fertilizer surface
Sulfur emulsion, through repeatedly spraying, and heats simultaneously, makes sulfur emulsion uniformly be applied to Diammonium phosphate (DAP) surface, altogether spraying 50L sulfur emulsion,
Wherein in sulfur emulsion, sulfur mass concentration is 50%, obtains sulfur-bearing 12.1% granulated di-ammonium phosphate containing fertilizer after being cooled to room temperature.Fertilizer
Grain surface has been wrapped one layer of fine and close sulfur anti-caking agent.
