Description
Technical field
The present invention relates to a kind of chemical fertilizer additive, more particularly to a kind of anti-powdering agent of composite fertilizer.
Background technology
Composite fertilizer grows some radiation shapes, straight, thickness such as hair or catkin shape, penniform semi-transparent in particle surface
Bright crystal, is touched with hand and fracture becomes powder, is then commonly called as " becoming mildewed " phenomenon in rapid dissolving on hand sometimes.And " whiting ", " length
Hair " and " efflorescence " can respectively regard the different phase of " becoming mildewed " as, and " whiting " is early stage, because internal and external factor influence may not
Continue to change, seem clearly for " whiting ", especially dark colour fertilizer；" efflorescence " is the later stage, due to inside and outside influence,
" becoming mildewed " is constantly broken, forms efflorescence.
In fertilizer market, through being commonly encountered composite fertilizer " whiting ", " becoming mildewed " and " efflorescence " phenomenon, composite fertilizer's " becoming mildewed ", " powder
Change " with " caking " equally, it has also become a great problem that composite heat transfer producer faces.In addition, existing composite fertilizer's balling ratio
Than relatively low, 70% is not almost reached, so stacked less than one month even less than a week in storehouse, be easy for efflorescence occur
Phenomenon.Composite fertilizer's " becoming mildewed ", " efflorescence " phenomenon drastically influence the condition outward appearance of fertilizer, and when peasant uses, sense organ is more impacted.
This also results in a large amount of dealers' return of goods and exchanges goods, and substantial amounts of economic loss is caused to composite heat transfer enterprise.Therefore, composite fertilizer is " long
Hair ", " efflorescence " seriously economic development of restriction fertilizer enterprises, therefore ask as chemical fertilizer production enterprise is in the urgent need to address
Topic.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of has that the anti-efflorescence ability of composite fertilizer is strong, improve composite fertilizer's balling-up
Rate, the cost for reducing composite fertilizer material, can strengthen fertilizer granule strength, reduce fertilizer agglomeration rate, improve fertilizer whiteness spy
The anti-powdering agent of composite fertilizer of point.
The anti-powdering agent of composite fertilizer of the present invention, including water soluble polymer resin and the inorganic salts with water imbibition effect；Its
In, the amount of described water soluble polymer resin is the 10~30% of the quality of the anti-powdering agent of composite fertilizer；It is described with water suction
Property effect inorganic salts amount for the anti-powdering agent of composite fertilizer quality 70~90%.
Optionally, the water soluble polymer resin described in the anti-powdering agent of composite fertilizer of the present invention be carboxymethylcellulose calcium and its
Two or more in salt, high molecular cellulose, polyacrylamide and lignosulfonates.
Optionally, the inorganic salts with water imbibition effect described in the anti-powdering agent of composite fertilizer of the present invention are calcium chloride and sulphur
One or two in sour sodium.
Further, described in the anti-powdering agent of composite fertilizer of the present invention water soluble polymer resin and with water imbibition effect
Inorganic salt particle size is 100~200 mesh.
The purposes of the anti-powdering agent of composite fertilizer of the present invention, addition of the anti-powdering agent of described composite fertilizer in composite fertilizer be
When 0.8~1.8%, with composite fertilizer's efflorescence is prevented, balling ratio is improved, strengthen fertilizer granule strength, low fertilizer agglomeration rate is improved
The effect of fertilizer whiteness.
The invention has the advantages that：
1st, the inorganic salts present invention uses water soluble polymer resin and with water imbibition effect.The nothing of water imbibition effect
Machine salt can be firmly adsorbed on compound fertilizer granules surface, can solve the problems, such as that particle top layer is excessive with core moisture content difference, and
Hydrophobic layer is formed, water soluble polymer resin then forms a coating film, prevents the contact between particle on compound fertilizer granules surface,
Improve balling ratio, and increase the intensity of compound fertilizer granules, so as to play the good result of anti-efflorescence.
2nd, balling ratio can be improved using the anti-powdering agent of composite fertilizer of the invention.This product than traditional additive clay,
Such as attapulgite, bentonite, kaolin, there is stronger caking property, and this product replaces clay in composite heat transfer, can improve
Balling ratio is so as to improve yield.Through experiment, 70% is about using prior art production high nitrogen fertilizer balling ratio, and added in composite fertilizer
After entering 0.8~1.8% product of the present invention, balling ratio improves 20%~30%, almost can reach balling ratio 100%.
3rd, cost of material can be reduced using the anti-powdering agent of composite fertilizer of the invention.Because of the anti-powdering agent of composite fertilizer of the invention
Addition in composite fertilizer is 0.8~1.8%, less than the addition of clay, so as to increase the tune of other formulas in fertilizer
Whole space.Because ammonium chloride unit nitrogen price is less than urea, the fertilizer of same nitrogen content is produced, it is possible to reduce more urea add
Dosage, increases more ammonium chloride additions, reaches the purpose for reducing cost of material.
4th, the anti-powdering agent of composite fertilizer of the invention can strengthen fertilizer granule strength.To addition 0.8~1.8% in composite fertilizer
Product of the present invention, granule strength improves 10~20N, so as to prevent granule atomization, reduces fertilizer agglomeration rate.
5th, the anti-powdering agent of composite fertilizer of the invention can improve the whiteness of fertilizer.The color of traditional clay is in canescence,
It is added into composite fertilizer, is a bit darkish in color；The color of the anti-powdering agent of this composite fertilizer is milky, is added into composite fertilizer, composite fertilizer
Particle surface is smooth shinny, white is presented, because that with traditional clay is that replaced, can improve the whiteness of fertilizer, so as to meet
Pursue the demand of the user of fertilizer whiteness.
6th, the application method of the anti-powdering agent of composite fertilizer of the invention is simple.Position addition directly can be delivered in raw material, i.e.,
Raw material conveyer belt position addition before compound fertilizer prilling machine.
In a word, the anti-powdering agent of composite fertilizer of the invention has that the anti-efflorescence ability of composite fertilizer is strong, quick improve composite fertilizer's balling-up
Rate, the cost for reducing composite fertilizer material, can strengthen fertilizer granule strength, reduce fertilizer agglomeration rate, improve fertilizer whiteness it is excellent
Point.Be aided with environmentally safe, biodegradable effect again, thus the anti-powdering agent of composite fertilizer of the present invention have it is inexpensive, low
Consumption, raw material sources enrich, easily produce and be easy to make an addition to the advantage in composite fertilizer.
