Problems solved by technology

[0005] In summary, on the one hand, the fertilizer dyes in the prior art have problems such as easy fading, uneven dyeing, non-degradable dye itself, and soil pollution; on the other hand, ordinary conditioners or dyes can only give ammonium phosphate Provide the single function of coloring or improving granules, and cannot simultaneously dye, improve the roundness and luster of granules; moreover, the use of common conditioners or coloring agents is not conducive to fertilizer efficiency and fertilizer utilization to a certain extent

preparation example Construction

[0057] The present invention also provides a preparation method of the ammonium phosphate conditioning agent described in the above technical scheme, comprising the following steps:

[0058] a) Mix tartrazine, polyethylene glycol, humic acid, polymerized amino acid, phosphoric acid and water to obtain an ammonium phosphate conditioner.

[0059] The invention mixes tartrazine, polyethylene glycol, humic acid, polymerized amino acid, phosphoric acid and water to obtain the ammonium phosphate conditioner. In the present invention, the process of said mixing is preferably specifically:

[0060] Add phosphoric acid into water, then add tartrazine, after being completely dissolved, then add polyethylene glycol, humic acid and polymerized amino acid in sequence, stir until completely dissolved, and obtain the ammonium phosphate conditioner. The present invention has no special limitation on the stirring method, and the technical solution of mechanical stirring or manual stirring wel...

Embodiment 1

[0079] (1) Add 2kg of phosphoric acid to 79kg of water under stirring conditions, then add 6kg of tartrazine, after completely dissolving, add 8kg of polyethylene glycol 400, 2kg of potassium humate and 3kg of polyaspartic acid successively, at 25 Stir at ℃ for 30 minutes until the solution is completely dissolved to obtain ammonium phosphate conditioner.

[0080] (2) Add the ammonium phosphate conditioner obtained in step (1) to the slurry before monoammonium phosphate granulation in an amount of 1 kg / t and mix evenly to obtain an ammonium phosphate product with smooth particle surface and uniform dyeing.

[0081] The sample photo of the ammonium phosphate conditioner that the embodiment of the present invention 1 obtains is referring to figure 2 Shown; The dyeing effect figure of the ammonium phosphate product that the embodiment of the present invention 1 obtains is referring to image 3 shown.

[0082] The ammonium phosphate product utilization rate (fertilizer effect) ...

Embodiment 2

[0090] (1) 5kg phosphoric acid is added in 77kg water under the condition of stirring, then add 7kg tartrazine, after treating to dissolve completely, then add 5kg polyethylene glycol 400, 5kg potassium fulvic acid and 1kg polyaspartic acid successively, in Stir at 25°C for 30 minutes until the solution is completely dissolved to obtain an ammonium phosphate conditioner.

[0091] (2) Add the ammonium phosphate conditioner obtained in step (1) to the slurry before diammonium phosphate granulation in an amount of 2 kg / t and mix evenly to obtain an ammonium phosphate product with smooth particle surface and uniform dyeing.

[0092] The dyeing effect figure of the ammonium phosphate product that the embodiment of the present invention 2 obtains is referring to Figure 4 shown.

[0093] According to the test method provided in Example 1, the utilization rate of the ammonium phosphate product provided in Example 2 of the present invention was tested, and compared with the unconditi...

Abstract

The invention provides an ammonium phosphate conditioner. The ammonium phosphate conditioner comprises the following components: 5wt% to 10wt% of lemon yellow, 5wt% to 10wt% of polyethylene glycol, 1wt% to 5wt% of humic acid, 1wt% to 5wt% of polymeric amino acid, 1wt% to 5wt% of phosphoric acid and the balance of water. Compared with the prior art, the ammonium phosphate conditioner provided by the invention adopts components of specific content, so that the synergistic effect can be realized and then an ammonium phosphate fertilizer is dyed uniformly to improve the roundness and luster of product particles so as to improve the appearance of the product. Furthermore, the fertilizer efficiency of the ammonium phosphate fertilizer can be increased, the soil aggregate structure is improved, and the growth of crops is stimulated to enhance the utilization rate of the ammonium phosphate fertilizer. Experimental results show that the ammonium phosphate product is smooth in particle surface and uniform in dyeing after conditioned by the ammonium phosphate conditioner, furthermore, compared with the ammonium phosphate fertilizer which is not conditioned, the utilization rate of the nitrogen fertilizer is increased by 7.01% to 10.14%, and the utilization rate of the phosphorus fertilizer is increased by 5.24% to 10.36%.

Description

technical field [0001] The invention relates to the technical field of chemical fertilizers, in particular to an ammonium phosphate conditioner and its preparation method and application. Background technique [0002] At present, with the implementation of the "Agricultural Supply-Side Structural Reform" policy proposed by the central government in 2015 and the implementation of the "Action Plan for Zero Growth in Fertilizer Use by 2020" formulated by the Ministry of Agriculture, the domestic compound fertilizer industry has a great improvement in terms of product structure and quality. With great improvement, the competition in the market is becoming more and more fierce. In addition, imported compound fertilizers have great advantages in appearance, quality and user acceptance, which intensifies the competition in the domestic compound fertilizer market. Manufacturers, sellers, and users of compound fertilizers have higher requirements for compound fertilizers not only on...
