Description
Technical field
The present invention relates to effervesce fertilizer and preparation method thereof.
Background technique
Effervesce fertilizer can discharge carbon dioxide, adjust the photosynthesis of plant, can also be by effervesce fertilizer to soil
Environment improve, and water temperature and ground temperature can also be improved, to prevent to plant using the heat of effervesce fertilizer acid-base reaction release
Object freeze injury.
Meeting water due to effervesce fertilizer can react, and produce carbon dioxide and water, and the increase of water has been catalyzed effervesce
The progress of reaction, short so as to cause the storage period of product, production process is also difficult to control, affects the stability of effervesce fertilizer.
Fertilizer is seasonal using article, and fertilizer enterprise needs to get ready the goods in advance, this there is storage problem, due to effervesce fertilizer
Water cannot be added when material production, it can only be by squeezing the Van der Waals force formed bonding, therefore hardness is not high, in storage and transportational process
In, under pressure, Yi Fasheng dusting, and then product is caused to agglomerate, inconvenience is caused to client's use.
In order to solve the problems, such as above-mentioned two, granulation mode uses anhydrous granulation mode as far as possible, just like melt granulation (such as US
6071539), dry method rolling granulation etc. should be avoided to use and make the molten of binder or binder with water according to wet granulation technology
Agent, and should be using Organics solvents such as ethyl alcohol, glycerol；Second is that using soda acid, separately the mode of pelletizing reduces soda acid contact surface, or will
Acid, alkali composition are wrapped up with other compositions, are avoided direct contact with, as used with polyethylene glycol (PEG) in technique to acid source
It is embedded；Three is also fine using starch, dextrin, sucrose, polyvinyl alcohol, Arabic gum, gelatin, ethyl cellulose and contracting methyl
It is a kind of water soluble effervescence composition and preparation method thereof that plain sodium, which is tieed up, as binder, such as patent name, application No. is
2008102173796.Using ethyl alcohol, glycerol as Organic solvent, although can be to avoid water is introduced, its viscosity be lower,
And glycerol is hygroscopic, although pellet hardness can be improved, hardness raising is simultaneously little, still remains dusting agglomeration problems；And
Using using starch, dextrin, sucrose, polyvinyl alcohol, Arabic gum, gelatin, ethyl cellulose and contracting sodium carboxymethylcellulose pyce conduct
Binder, in the case that these binders need water, bond effect is just obvious, and effervesce fertilizer strictly limits the content of moisture,
Water content is seldom, its bond effect is not obvious with this condition, such as the food starch that our markets are bought, in packaging bag not
With viscosity, therefore, dusting agglomeration problems can not be solved；The production technology trouble by the way of isolation, due to isolation film
Solution rate is slow when in the presence of, use, and fertilizer efficiency plays relatively slow, and production and use are restricted.
Therefore, market, which is not able to solve, improves effervesce fertiliser granulates hardness, reduces effervesce fertilizer and is storing and transporting
The mature technology of dusting and the agglomeration of process.
Summary of the invention
The present invention provides effervesce fertilizer and preparation method thereof, and solving technical problem is 1) to improve effervesce fertiliser granulates hardness；
2) effervesce fertilizer is reduced in the dusting and agglomeration of storage and transportational process.
In order to solve the above-mentioned technical problem, the invention adopts the following technical scheme:
