Example Embodiment

[0015] Example 1

[0016] The powder compound fertilizer anti-caking agent of this embodiment contains the following components by weight percentage: nepheline powder 90%, sodium oleate 10%

[0017] The preparation method is as follows: adding 600 mesh nepheline powder and dried sodium oleate to the powder modification equipment, controlling the temperature at 60°C, stirring for 20 minutes, and cooling after modification to prepare the powder compound fertilizer anti-caking agent. When in use, 2.8 kg of the anti-caking agent prepared in this implementation is sprayed per ton of fertilizer, which can effectively ensure that the fertilizer will not agglomerate for 6 to 8 months, and there will be no large lumps in the appearance. Up to 98%.

Example Embodiment

[0018] Example 2

[0019] This embodiment contains the following components by weight: 85% nepheline powder, 15% sodium oleate

[0020] The preparation method is: adding 800 mesh nepheline powder and dried sodium oleate into the powder modification equipment, controlling the temperature at 65 DEG C, stirring for 10 minutes, and cooling after modification to prepare the powder compound fertilizer anti-caking agent. When in use, spraying 2.5 kg of the anti-caking agent prepared in this implementation for each ton of fertilizer can effectively ensure that the fertilizer will not agglomerate for 6 to 8 months, and the appearance of the fertilizer will not be large, and it will be broken by hand crushing, and its anti-caking rate will be tested Up to 98%.

Example Embodiment

[0021] Example 3

[0022] This embodiment contains the following components by weight percentage: nepheline powder 88%, sodium oleate 12%

[0023] The preparation method is: adding 1200 mesh nepheline powder and dried sodium oleate into the powder modification equipment, controlling the temperature at 70°C, stirring for 15 minutes, and cooling after modification to prepare the powder compound fertilizer anti-caking agent. When in use, spraying 2.6 kg of the anti-caking agent prepared in this implementation per ton of fertilizer can effectively ensure that the fertilizer will not agglomerate for 6 to 8 months, and the appearance of the fertilizer will not be large, and it will be crushed by hand, and the anti-caking rate will be tested. Up to 98%.

Abstract

The invention relates to a powdery compound fertilizer anti-caking agent and a preparation method therefor. The powdery compound fertilizer anti-caking agent comprises the following components in percentage by weight: 85-90% of inorganic powder and 10-15% of modifiers. The inorganic powder is nepheline powder, and the modifiers are sodium oleate. The preparation method for the compound fertilizer anti-caking agent comprises the following steps: adding inorganic powder of 600-1200 meshes and modifiers into powder modifying equipment, controlling the temperature to be 60-70 DEG C, stirring the mixture for 10-20 minutes, and cooling down the mixture to obtain the powdery compound fertilizer anti-caking agent. The powdery compound fertilizer anti-caking agent has the following advantages: low costs; convenient use and addition, thereby facilitating popularization and use; no pollution to human bodies and lands, thereby facilitating environmental protection; and good anti-caking effects, thereby ensuring that fertilizer will not be caked in 6-8 months.

Description

technical field [0001] The invention relates to an anti-caking agent, in particular to a powder compound fertilizer anti-caking agent and a preparation method thereof. Background technique [0002] At present, the main problem of compound fertilizer production in our country is that the product is easy to agglomerate, which makes it difficult for farmers to use it and seriously affects the product quality of production enterprises. Enterprises have to use various anti-caking agents to achieve the purpose of anti-caking. In order to solve the caking problem of compound fertilizers, various fertilizer companies and scientific research institutes have conducted in-depth research on this subject, and have developed targeted anti-caking agents for different types of fertilizers. Our country produces tens of millions of tons of compound fertilizers every year, most of which use oil-soluble anti-caking agents, which consume a large amount of mineral oil every year, with high usage ...
