Formula composition and principle of anti-caking agents for compound fertilizers
Thread Content
Composition and principles of anti-caking agents for compound fertilizers (for detailed information, contact via mobile phone 13207228022). Anti-caking agents are primarily composed of crystal phase inhibitors, hydrophobics, enhancers, dispersants, emulsifiers, water, and water-soluble natural colorants. The functions of each component are as follows: (1) Phase inhibitor: It is the surfactant that plays a key role; its hydrophilic groups bind to the surface of the fertilizer particles through hydrogen bonds, while the hydrophobic groups remain on the outside of these particles. (2) Hydrophobic agents: Hydrophobic agents also possess the properties of surfactants; their hydrophilic groups can bind to fertilizer particles, while their hydrophobic groups are arranged on the surface of these particles. However, its binding strength is weaker than that of phase inhibitors; the hydrophobic groups of the hydrophobizing agents can more easily combine with those of phase inhibitors, thereby forming a denser hydrophobic film on the surface of the fertilizer particles. (3) Reinforcing agents: These are mainly polymeric substances that can form a network structure on the surface of fertilizer particles, thereby enhancing the strength of the hydrophobic layer on their surface. This prevents the hydrophobic layer from being damaged when exposed to temperature changes, compression, humidity, or other conditions. (4) Emulsifier: A surfactant with higher polarity, which can combine an aqueous solution of naturally water-soluble colorants with hydrophobic agents, and enable strong bonding between the colorants and the hydrophobic agents. (5) Natural water-soluble colorants: After the application of chemical fertilizers, these colorants combine with anti-caking agents on the surface of the fertilizer particles, thereby coloring the outside of those particles. Moreover, after the use of chemical fertilizers, the colorant can dissolve quickly in the soil, preventing it from accumulating there and causing environmental pollution.

The amine value of octadecylamine is used as a testing parameter; how does the level of this amine value affect the effectiveness of anti-caking agents?
Why use octadecylamine? I don’t see any point to it
Why is it not interesting? Please explain in detail

So, one shouldn’t be limited to raw materials; this way, you’ll have more room for creativity. Adding octadecylamine ensures no caking? The product will definitely clump together without octadecylamine, right? Not necessarily
The compound fertilizers produced these days are no longer limited to octadecylamine, engine oil, and paraffin. I once talked with a manufacturer of anti-caking agents; nowadays, for better results and a better cost-performance ratio, octadecylamine is just one of various surfactants. The specific amounts used as well as other surfactants are considered confidential and generally not available to outsiders
Octadecylamine should be classified as an intermediate among cationic surfactants; it can barely be considered a surfactant. Paraffin is a surfactant, and paraffin along with alcohols represent the two extreme forms of surfactants. Hehe, I haven’t worked as a anti-caking agent for many years; I’m not sure if what I say is accurate
I thought that by clarifying the following issues, it would be possible to truly find a way to prevent compound fertilizers from caking. 1. What is the mechanism behind the caking of compound fertilizers? 2. What causes compound fertilizers to clump? 3. Why isn’t the newly produced compound fertilizer in a clumped form? What do you all think? Friends at sea, please point out any mistakes.
Hehe. Here, anti-oiling agent and powder are added together and mixed into the drum
