AI Technical Summary

Problems solved by technology

The main carrier of powdery anti-caking agent is non-metallic mineral, which is insoluble in water and cannot be degraded, which has a relatively large impact on the environment. At the same time, the inert powder has a general effect due to its poor adhesion.
[0008] 3. Problems in the application of anti-caking agent
The big problem at present is that the mineral oil powder cannot be fixed on the surface of the granules well, or it cannot be wrapped, or it is easy to fall off after being wrapped. The anti-caking and isolation effect of fertilizer will be greatly reduced, and the overall anti-caking effect cannot be guaranteed. Petroleum products such as mineral oil and alkylamine can no longer meet the current environmental protection requirements.

Abstract

The invention discloses a fertilizer anti-caking agent as well as a preparation method and application thereof. A fertilizer anti-caking agent is characterized by comprising the following raw materials in percentage by weight: 10-20% of C8-C20 fatty acid and fat of fatty acid, 3-5% of C12-C20 natural fatty alcohol, 5-10% of nano-scale silicon dioxide, 65-82% of plant natural straw, wherein the sumof the components is 100%. The fertilizer anti-caking agent is prepared by secondary modification and one time compounding. When the fertilizer anti-caking agent is used, the fertilizer anti-caking agent is uniformly applied to the surface of the fertilizer particles by adopting a spiral conveyor according to the amount of 2.5-4.0 kg / ton. The fertilizer anti-caking agent can form a layer of diaphragm on the surface of the fertilizer particles, so that the fertilizer is kept loose for a long time, good liquidity is achieved, and the quality of the fertilizer is guaranteed.

Description

technical field [0001] The invention relates to the technical field of fertilizer anti-caking treatment, in particular to a fertilizer anti-caking agent and a preparation method and application. Background technique [0002] 1. Overview of anti-caking agent [0003] Anti-caking agents are additives designed to promote good flow of fertilizers during storage and handling operations. In order to prevent fertilizer agglomeration, fertilizer manufacturers mainly use the method of coating fertilizer with anti-caking agent while improving process conditions and controlling particle characteristics. The use of anti-caking agent can minimize fertilizer agglomeration, moisture absorption and Pulverization phenomenon, increase the fluidity of particles, and facilitate the storage, transportation and use of fertilizers. Therefore, as a low-cost, high-yield anti-caking measure, anti-caking agents have now been widely used by compound fertilizer manufacturers all over the world. Accept...
