Bulk materials

Bulk materials are materials that can be transported, stored and processed in loose form. They play an important role in surface technology, as the surface treatment of bulk materials enables a wide range of applications. Coating is a common process in the surface treatment of bulk materials. This involves applying a thin layer of a different material to the surface of the bulk material in order to improve or change certain properties. For example, bulk materials can be coated to make them water-repellent, corrosion-resistant or electrically conductive.

Another important process is granulation or pelletizing. Here, bulk materials are processed into uniform, granular particles, which facilitates their handling and use in various applications. This process also makes it possible to distribute additives or active ingredients evenly and improve the solubility or reactivity of the bulk materials. In addition, sieving plays a crucial role in the surface engineering of bulk materials. Sieving removes unwanted particles or impurities from the bulk materials, resulting in a more uniform surface and improved quality.

In some cases, grinding or crushing of bulk materials is also used to reduce their particle size and increase their surface area. This allows them to mix better with other materials or provide a larger surface area for chemical reactions. Overall, the various surface technology processes play an important role in optimizing bulk materials for their respective applications. They make it possible to improve the properties and handling of bulk materials and expand their potential uses in various industries.
