Definitions
- the present invention relates to the field of coating compositions applied to granular materials, such as granular fertilizers, in order to improve their quality and to obtain easier, longer and safer storage.
- a granular material is a discrete solid particle which can be produced by many different chemical or mechanical processes in which one or more components are consolidated.
- Fertilizers are materials that provide one or more of the nutrients that are necessary for the proper development and growth of plants. These can be, for example, chemical or mineral fertilizers, manure or plant residues. Fertilizers are usually in the form of granular materials, since this facilitates their storage, transport and use in the fields. There are many known processes for preparing fertilizers in the form of granular material, such as granulation, crystallization, crushing, grinding, grinding and compaction, among others.
- Fertilizers and other mineral products are often stored in large quantities over different durations. Many of them have a tendency to agglomerate during storage and to generate a large amount of dust during transport. The agglomeration can make the transportation and use of fertilizers and other mineral products difficult, very difficult or even impossible, insofar as they cannot flow properly. In addition, the dust generated during transport and during the loading and unloading operations of such products can cause serious health and safety problems as the atmosphere can become saturated with fine mineral particles.
- a common solution to reduce such problems is to apply a thin coating of a liquid or solid formulation on the particles.
- This coating prevents or slows down the agglomeration process and suppresses or at least reduces the generation of fine dust from the surface of the particle, for example a fertilizer or mineral or other product.
- the coating in liquid form, is usually sprayed onto the particles before storage.
- Known coating formulations of this type are mainly based on mineral oils, often comprising surfactants in order to reduce any effect. agglomeration. These formulations can also contain other components which modify the viscosity of the formulation such as waxes.
