Description
Technical field
The invention belongs to water soluble fertilizer technical field, more particularly, to the preparation method of a great number of elements water-soluble fertilizer.
Background technology
Agricultural is the first big source of China's pollution, and it, which is related to caused by chemical fertilizer production, pollutes, and is directed to use chemical fertilizer
Caused water pollution.Although it is maximum pollution sources, although also organic fertilizer, bio-fertilizer account for very big market, chemical fertilizer
Or indispensability fertilizer, in very long one period, large-scale use of still having on agricultural planting.
With social development, science and technology and cognition are constantly lifted, and chemical fertilizer is gradually understood to " traditional fertilizer ", and it is wrapped
Include conventional Chemical Mixed Fertilizer, Blending Fertilizer etc., and the water-soluble fertilizer made based on chemical industry or agricultural industrial chemicals, it has been " new, environmentally friendly
Type fertilizer ".It is somebody's turn to do " new, environment-friendly type fertilizer " and is embodied in national policy《To the year two thousand twenty fertilizer application amount zero growth rate action side
Case》In be previously mentioned " ... with reference to efficient water-saving irrigation, the technology such as Demonstration And Extension fertigation, sprinkler irrigation fertilization, promote liquid manure
The lower ground of one, improves fertilizer and water resource utilization efficiency ", this target is realized, only water-soluble fertilizer can be used, and this is state
Family advocates what is used, is not " chemical fertilizer " that zero growth rate is realized in scheme, nor being dissolved in water by complex fertilizer serves as water
What molten fertilizer can was realized.
A great number of elements water-soluble fertilizer has national sector standard, and standard No. is NY 1107-2010.End in July, 2017
Query site result in " St Chemical Fertilizer Q Supervision ＆ Testing Center (Beijing) " on the 26th shows that the whole nation obtains such fertilizer altogether
Formal and temporary registration certificate 1494, through random inspection, belong to only 17.5% or so (but of market circulation of water aqua type
It is water aqua type to have 5% or so), other are powder-types.
The water-soluble fertilizer of powder-type, and the making of Blending Fertilizer are very nearly the same, distinguish mainly in the content of impurity, typically
After finished product packing all without influence use, but be dissolved in water using when just embodied inadaptability, such as：(1) in being formulated not
Chemical reaction is mutually produced with raw material, so as to reduce nutrient availability, after being dissolved in water, or even it is more than hour to place 1
Muddy and precipitation occurs；(2) impurity is inevitably present, causes shower nozzle, dropper etc. to block；(3) can only use substantial amounts of
Aqueous medium is dissolved, and can not progressively be dissolved to water saturation state on a small quantity, because can so cause mixed erosion, precipitation etc. bad anti-
It should produce；(4) usually, acid stronger, the equipment such as perishable pipeline.
And a great number of elements water-soluble fertilizer of water aqua type, clear liquid type and floating type can be divided into again, we can intuitively can manage
Xie Wei：The fertilizer of clear liquid type is as clear as crystal, chemical property is stable, its aesthetic appearance is strong, and the fertilizer of floating type then have it is many suspend it is former
Expect particle, opaque, unlimpid, chemical property there may be unstable, such as layering, crystallization etc. for a long time.The contrast of advantage
On, clear liquid type fertilizer then has the requirement for being adapted to the micro- spray of highest level, will not block hole, long-time storage even dissolves
Yu Shuihou will not also produce ammonia taste, conglomeration, into cream, crystallization separate out, layering, the bad phenomenon such as precipitation, appearance is fabulous, during use
Also quickly can mix well in water, this is also the advantages of clear liquid type fertilizer is irreplaceable, and it also represent a great number of elements Water soluble fertilizer mesh
Preceding state-of-the-art technology, this is also the product of the invention to be done.
From the point of view of manufacture craft, most enterprises are when producing water aqua type a great number of elements water-soluble fertilizer, more using Blending Fertilizer
Make common material and thinking is made by mixing, various raw materials are dissolved in water to greatest extent, and add synergist, suspending agent, prevent
Crystallizing agent, thickener, antifreezing agent etc..But the making thinking based on Blending Fertilizer, although can also produce the water aqua type that index meets
The water-soluble material of a great number of elements, but effect is often had a greatly reduced quality.
So-called effect gives a discount, it will be understood that：Conventional Chemical Mixed Fertilizer, the low of plant recovery of nutrient of Blending Fertilizer are industry institutes
It is generally acknowledged, if the production of water-soluble fertilizer and using conventional Chemical Mixed Fertilizer and the preparation method of Blending Fertilizer, nothing more than being exactly by it
Water is dissolved in, so, more reduces effective utilization of nutrient on the contrary.Simultaneously as every liter of the technical requirement of product
Total nutrient (N+P that must be containing 500g in liquid fertilizer2O5+K2O), therefore selectable raw material range is considerably less, general enterprises
The raw material that capital Selective dissolution degree is big and total nutrient is higher, such as：Urea (total nutrient 46%), urea ammonium nitrate (total nutrient 32g/
L), potassium chloride (total nutrient 60%) Diammonium phosphate (DAP) (total nutrient 74%), APP (total nutrient 44g/L) etc..On the other hand,
When using the relatively very low but high total nutrient raw material of solubility, such as potassium dihydrogen phosphate (total nutrient 85%), potassium nitrate (total nutrient
58%) when, a great number of elements water-soluble fertilizer for being just necessarily used for floating type produces.
Mode based on conventional Chemical Mixed Fertilizer, Blending Fertilizer goes to produce water-soluble fertilizer, also results in the original of many high nutrient contents
Material can not use, because these raw materials are not easy to be absorbed by crops in itself or have adverse reaction to crop, such as potassium pyrophosphate, phosphoric acid
Hydrogen dipotassium, potassium formate etc..And clear liquid type water-soluble fertilizer is made, chemical reaction is reasonably make use of, will can be not easy to be absorbed by crops
Or there is the raw material of adverse reaction to be changed into another kind to crop and be easily absorbed by crops the compound for not having adverse reaction, this
And clear liquid type water-soluble fertilizer is maximum different from other water-soluble fertilizers (water-soluble fertilizer of such as floating type), and core technology
One of.
In addition, to meet the index of trace element, the trace element compounds such as copper sulphate, boric acid are often used again,
Also using moderate-element compounds such as calcium nitrate, magnesium sulfate.
The product investigation and analysis of online Baidu search and Alibaba are based primarily upon, due to the natural limitation of raw material, with
And the problem of technical merit, the water aqua type a great number of elements water-soluble fertilizer that most enterprises are produced are mostly floating types, clear liquid type
A great number of elements water-soluble fertilizer account for the 20% of water aqua type a great number of elements water-soluble fertilizer less than, that is to say, that a large amount of members of clear liquid type
Plain water-soluble fertilizer has fertilizer registration card to be less than 1494 × 17.5% × 20% ≈ 53 in the whole nation, and national quantity is substantially few.
Detected for the clear liquid type a great number of elements water-soluble fertilizer being commercially available, total nutrient can generally reach 500g/L's
Technical indicator, still, micro- majority comprise only one or both of boron, zinc, and few enterprise can accomplish to contain three simultaneously
More than kind of trace element, accomplish micro- not find temporarily containing five kinds simultaneously.Also just due to technical difficulty this because
Element, the company of domestic several Liquid Fertilizer production bases for being known as maximum, also simply mainly sells raw material.
Therefore analysis is drawn, a great number of elements water-soluble fertilizer of clear liquid type contains more than three kinds trace elements and meets industry mark
Accurate production is great difficulty, especially accomplishes containing five kinds of trace elements and to meet professional standard simultaneously, the type fertilizer
Material can be described as represent the current high-tech of water-soluble fertilizer.
With reference to some patents, such as《A kind of a great number of elements water-soluble fertilizer containing humic acid and preparation method thereof
CN201710031010.5》, it includes humic acid, ethylene glycol, urea, phosphoric acid, potassium hydroxide, AEO, sulphur
Sour zinc, ferrous sulfate, boric acid, lauryl sodium sulfate, it will be apparent that, crop is the potassium for the potassium hydroxide that can not absorb caustic potash
Element, it is necessary to which phosphoric acid and potassium hydroxide carry out reaction generation potassium dihydrogen phosphate (acidity) can just be absorbed by crops.But these
It is related to a problem, the solubility of potassium dihydrogen phosphate is too low, and in a kettle, ferrous sulfate is in alkalescence or local
Yellow iron ion flocculence material can be directly generated under conditions of alkalescence, and (final at most also only remaining micronutrient boron, zinc are to have
Imitate state), very conference causes fertilizer integral black to the amount added by humic acid relatively again, so, to the end of all reactions, it will turn into
The mixture of mixed erosion type, clear liquid type a great number of elements Water soluble fertilizer is to realize.Meanwhile although a great number of elements water is hung in the invention
The name of molten fertilizer, but that in fact make is (agricultural industry criteria NY 1106-2010) containing humic acid water-soluble fertilizer.

Change potassium and potassium sulfate carries out network, accelerate the dissolving of potassium chloride and potassium sulfate in water.The invention is the production of powder-type, but
The existing technical thought non-fully made by the way of Blending Fertilizer physical mixed.But trace element is but not so good as people
Meaning, also only two kinds of boron, zinc.
In summary, it is found that the problem of clear liquid type a great number of elements water-soluble fertilizer prior art is present has：
(1) market survey is found and existing patented technology is shown, a great number of elements water-soluble fertilizer even powder of water aqua type
Formulation, due to zinc and boron dissolves easily in water and easily affine particularity, and industry is also more using in only addition trace element
Zinc and boron, from the perspective of balance formula, trace element others ferrous iron, copper, manganese, molybdenum are all difficult to exist in formula, its pole
Easily (it is difficult to add with chemically reactive, also not all right even with EDTA Chelating states such as the raw material such as phosphate of a great number of elements
Enter dissolving), this is the technical threshold for being difficult to cross over that industry presently, there are, and is not intended to add what is just added, nor ability
Prior art well known to field technique personnel；
(2) Blending Fertilizer or Chemical Mixed Fertilizer can correspond to numerous formula with a technical matters, still, clear liquid type it is a large amount of
Element water-soluble fertilizer is not all right：Each formula can only correspond to a technical matters, and formula can only somewhat change in very low range
Become；Beyond the control (such as pH and temperature) of control parameter scope, even if formula is constant, clear liquid can also become mixed erosion even pasty state；
(3) due to not using the mode of production of reactor compared with multiple enterprises, but use and be similar to Blending Fertilizer physical agitation
The normal agitation mode of production, therefore it is relative lacked the advantage means such as polymerisation, raw material range is narrow used by causing
(kind concentrations are in the raw material selection of conventional Chemical Mixed Fertilizer, Blending Fertilizer), it is impossible to as patent CN201410415592.3
Using the raw material (such as potassium formate, potassium pyrophosphate) of various unconventional property, because once using, it will cause crop failure even
It is dead.
(4) do not save, the heating stirring described by some patents was for up to 2 hours.
