Kuivaruiskuprosessi

Kuivaruiskuprosessi, also known as dry spraying, is a manufacturing technique used for applying powdered materials, typically plastics or metals, onto a substrate. This process involves atomizing the powder into a fine mist and then propelling it towards the surface to be coated. The particles adhere to the substrate through a combination of electrostatic forces and thermal energy, which can be applied externally or generated by the process itself.

In a typical kuivaruiskuprosessi setup, the powder is fed from a hopper and then dispersed into a stream of carrier gas. This gas, often air or an inert gas, carries the powder particles through a nozzle or gun. Various methods exist for activating the particles, such as heating the powder stream or using electrostatic charging. Upon impact with the substrate, the particles melt or sinter, forming a cohesive and continuous coating. The temperature of the substrate can also be controlled to optimize adhesion and the final properties of the coating.

The kuivaruiskuprosessi is employed in a wide range of applications. It is commonly used for applying protective coatings, such as corrosion-resistant layers or wear-resistant surfaces, onto metal components. In the automotive industry, it can be used for interior trim components. It is also utilized in the aerospace sector for creating specialized coatings with enhanced thermal or electrical properties. The versatility of the process allows for the coating of complex shapes and geometries, making it a valuable technique in modern manufacturing.
