Abstract
A kind of Joint Production method of calcium sulfate crystal whiskers and urea ammonium nitrate solution, belongs to field of inorganic chemical engineering.It includes the reaction of calcium nitrate and ammonium sulfate;Add crystallization aid;It is mixed;The filtering of mixed liquor;Washing and drying to filter residue;The concentration of filtrate is reconciled;Filtrate is mixed with urea;Product packaging is examined and is put in storage.Production cost of the present invention is low, simple for process, and easy to operate.High practicability and generalization.
Description
Technical field
The invention belongs to technical field of inorganic chemical industry.
Background technology
The present invention relates to the background technologies of two aspects, are on the one hand the background technologies in terms of calcium sulfate crystal whiskers, another
Aspect is the background technology in terms of ammonium nitrate fertilizer.The technical background of calcium sulfate crystal whiskers is introduced first, and calcium sulfate crystal whiskers refer to tool
There are uniform cross section, complete shape, the fibrous monocrystal of perfect internal structure.When CaSO4 content >=98%, sulfuric acid
The average aspect ratio of calcium pyroborate is 10~200.Calcium sulfate crystal whiskers are widely used in high molecular material, it can not only increase
The intensity and toughness for adding material can also play thickening, heat-resisting, wear-resisting, the effect of oil resistant.Calcium sulfate crystal whiskers are than other whiskers
Product price is cheaply very much, and performance is suitable, and manufacture craft is simple, and excellent cost performance makes the market of calcium sulfate crystal whiskers
It is very wide.
About the background technology of ammonium nitrate, ammonium nitrate is a kind of purity nitrogen fertilizer that nitrogen content is 35%, is highly soluble in water, is easy
Moisture absorption is lumpd, and when being clashed or high temperature, is easy to happen explosive decomposition reaction.From 2002, China was by nitric acid
Ammonium is classified as civil detonation product, and from this China, fertilizer market forbids pure ammonium nitrate nitrogenous fertilizer to buy and sell.Legal requirement is to agricultural ammonium nitrate fertilizer
Material is improved, and so that it is lost explosive and unreducible rear and be can be used as fertilizer sales and use.Currently on the market to nitric acid
The improved goods of ammonium is mainly calcium ammonium nitrate and urea ammonium nitrate solution(Liquid Fertilizer), both fertilizer products all meet the method in China
Laws & Regulations, and since supply falls short of demand always in the market in fertilizer for its good fertilizer efficiency.
Invention content
The main object of the present invention has at 2 points, first, providing, a kind of product purity is high, and crystal form is good, and low energy consumption, technique letter
Single, environmentally safe calcium sulphate crystal whisker preparation method;Secondly providing a new production way for urea ammonium nitrate solution
Diameter.
The present invention adopts the following technical scheme that realize that object above, specific production stage be:
1. allocating the calcium nitrate solution that mass concentration is 15%~80% and the ammonium sulfate that mass concentration is 10%~50%.It will be real
Border participates in the calcium nitrate of chemical reaction and the amount ratio of the substance of ammonium sulfate is controlled in 1 ︰ 1 or so, and corresponding mass ratio is about
1.24 ︰ 1.
2. two kinds of solution are mixed, and crystallization aid is added,(Adjuvant can be that crystal-directing-agent calcium sulfate is brilliant
Must, can also be crystal modifier magnesia or magnesium sulfate), the wherein quality of crystal-directing-agent is about to generate calcium sulfate quality
1%, the quality of crystal modifier is the 0.1%~3% of calcium nitrate quality, and at 20 DEG C~100 DEG C, mixing speed is control temperature
50~300RPM, it is 20~80 minutes that the time, which is mixed, and two kinds of solution is made fully to react.
3. gained mixed liquor is filtered, dry to gained residue washing, and fully, products obtained therefrom is calcium sulfate crystalline substance
Palpus.
4. gained filtrate is ammonium nitrate solution after filtering, the ammonium nitrate for the urea ammonium nitrate solution allocated as needed is dense
Filtrate is concentrated or is diluted by angle value, and the urea for needing dosage is then added in the solution, after being sufficiently stirred, gained production
Product are urea ammonium nitrate solution.
5. two kinds of products are packed respectively, and examine storage.
The raw material that this technical solution uses is calcium nitrate and ammonium sulfate, and source is sufficient, cheap.Gained calcium sulfate crystal whiskers
Product, crystal form is good, and purity is more than 99%, and whiteness is more than 95%.Another product of gained is urea ammonium nitrate solution, belongs to purity nitrogen liquid
Body fertilizer, containing nitrate nitrogen, ammonium nitrogen and urea state nitrogen, fertilizer efficiency are good.Required production equipment is simple, and technical maturity entirely produced
Journey is environmentally protective, is generated without poisonous and hazardous byproduct.
Description of the drawings
Specific implementation mode provides specific embodiment by legend.What Fig. 1 was provided is a kind of calcium sulfate crystal whiskers and urea nitre
The process flow chart of the Joint Production method of acid ammonium solution, it includes the mixing of calcium nitrate solution and ammonium sulfate, crystallization auxiliary
The addition of agent, stirring make reaction abundant, the filtering to mixed liquor, washing and drying to filter residue, the reconciliation to filtrate, with urea
Mixing storage is examined to the packaging of products obtained therefrom calcium sulfate crystal whiskers and urea ammonium nitrate solution.
Claims (2)
1. the Joint Production method of a kind of calcium sulfate crystal whiskers and urea ammonium nitrate solution, is mainly characterized by:By calcium nitrate solution and
Crystallization aid is added in reaction in ammonium sulfate hybrid reaction, waits after the completion of reacting, and gained mixed liquor is filtered, will
The calcium sulfate residue washing of gained, and be dried, to obtain calcium sulfate crystal whiskers.
2. a kind of Joint Production method of calcium sulfate crystal whiskers and urea ammonium nitrate solution as described in claim 1, main feature
It is:The concentration of the ammonium nitrate filtrate of gained is reconciled, and adds and the urea of dosage is needed to be mixed, to obtain urea
Ammonium nitrate solution.
