Description
Technical field
The present invention relates to Blending Fertilizer manufacturing field.The preparation method of mainly a kind of special damp-proof urea of Blending Fertilizer.
Background technology
China is a large agricultural country, and various fertilizer, especially chemical fertilizer play indelible tribute to China's grain security
Offer.
The demand of grain drives the explosive growth of Chinese chemical fertilizer, past 10 years, all kinds of fertilizer enterprises up to 6000 of China
More families, mostly compound fertilizer enterprise, they use granular urea, phosphorus ammonium, potassium chloride or potassium sulfate again after carrying out break process
Steam dram is granulated, or high-tower granulation after melting, is zero for fertilizer nutrient contribution.With our Chinese fertilizer patterns completely
The different U.S., then be based on Blending Fertilizer, Blending Fertilizer be exactly by granular urea, particle phosphorus ammonium and granular potash fertilizer physical mixed and
Into eliminating the secondary operation of composite fertilizer, therefore Blending Fertilizer (also referred to as BB fertilizer) more low-carbon and economy.
In recent years, the Northeast of China also slowly started to apply Blending Fertilizer, and peasant household buys various straight fertilizers, common nitrogen
Fertilizer is such as:Granular urea, conventional phosphate fertilizer is such as：The particle Diammonium phosphate (DAP) of high concentration, particle MAP and rich in phosphorus and calcium,
Micro- general calcium and coarse whiting in magnesium, sulphur etc., conventional potash fertilizer are exactly granule potassium chloride, potassium sulfate.In these fertilizer, general calcium
A kind of cost-effective phosphate fertilizer, its price is much lower compared with MAP and Diammonium phosphate (DAP) and middle micro-element nutrition more comprehensively,
Because the production of general calcium is made with sulfuric acid and ground phosphate rock directly reaction, it is a kind of fertilizer of slant acidity, is providing phosphorus nutrient
Meanwhile all keep down various metal trace elements in ground phosphate rock and moderate-element, plus the slant acidity of general calcium, also may be used
To promote in soil by fixed nutrient again by crop utilization, thus it is better using the crop growing state of general calcium, it is also deep
Approved by peasant.
But the acidic character of general calcium, cause it to be contacted with urea, because the sulfuric acid meeting remained in general calcium and urea
Reaction forms ureasulfuric acid, in liquid, also result in peasant and is being mixed with Blending Fertilizer by the use of general calcium as phosphorus source and urea, potash fertilizer
When, there is fertilizer and get wet, it is agglomerating, the problem of can not applying fertilizer.
Because this problem, the development of Blending Fertilizer is also constrained to a certain extent.
Therefore, in this context, prepare a kind of using general calcium and urea as the Blending Fertilizer tailored version urea of raw material, turn into
The task of top priority.
The content of the invention
The invention reside in providing a kind of preparation method of the special damp-proof urea of Blending Fertilizer, urea made from this method can be with
Stablize mixing with acidic fertiliziers such as general calciums, nonhygroscopic, constant tide, greatly widened the material fertilizer species of Blending Fertilizer.
A kind of preparation method of the special damp-proof urea of Blending Fertilizer, it is characterised in that：In coating drum front end, disk or
Granular urea is put into blender with mixed function, in one layer of special anti-blushing agent of granular urea surface spraying；Then wrapping
In membrane cylinder rear end, disk or in the blender with mixed function, then one layer of modified magnesium powder end is sprayed, that is, be made and mix
The special damp-proof urea of complex fertilizer.
Described granular urea is granular urea, fluidized bed prilling prepared by granular urea, drum equipment prepared by high tower
One or two or more kinds of mixtures in granular urea prepared by the granular urea of preparation, extrusion technique.
Described special anti-blushing agent for Hubei Forbon Technology Co., Ltd. product HISOFT FA130, by weight hundred
Divide than meter, composition is the mixture of 10-30% dextrin, 5-50% Macrogol 4000 and 30-80% water.
The preparation method at described modified magnesium powder end is：By magnesia original powder and quality be magnesia quality 0.5-
One or two or more kinds of mixtures in 10% paraffin, vegetable oil or mineral oil are well mixed, and are ground to 200-2000
Mesh, that is, modified magnesium powder body is made.
Described melting point of paraffin wax is 20 DEG C -120 DEG C.
The advantage of the invention is that：
1st, it is simple and quick.The system of the special damp-proof urea of Blending Fertilizer can be achieved in spraying in existing fertilizer pack roller
It is standby；
2nd, without returning charge.Packing and storing system is directly entered after parcel；
3rd, with anti-caking function.Urea granules are loose made from this method, it is no longer necessary to extra addition fertilizer anti-caking
Agent；
4th, efficiently moistureproof isolation.Two layers of efficient moistureproof isolation processing, urea and general calcium can be avoided completely or other are aqueous
High fertilizer medium contact is measured, realizes preferable isolation effect.
