Koronatöötlus

Koronatöötlus refers to a specific type of industrial process. It involves the application of a low-temperature plasma to the surface of a material. This plasma treatment is used to modify the surface properties of various substrates without significantly altering their bulk characteristics. The primary goal of koronatöötlus is to enhance surface energy, improve adhesion, and increase wettability.

The process typically uses a high-voltage electrical discharge in a low-pressure gas or at atmospheric pressure. This discharge generates a plasma, which is an ionized gas containing free electrons, ions, and neutral species. When this plasma interacts with the material's surface, it can induce chemical and physical changes. These changes can include the introduction of polar functional groups, etching of the surface, or cross-linking of polymers.

Koronatöötlus finds applications in a wide range of industries. It is commonly used in the manufacturing of plastics, textiles, and printing. For example, it can prepare plastic films for subsequent coating or printing, allowing inks and adhesives to bond more effectively. In the textile industry, it can improve the dyeability and water repellency of fabrics. The automotive and medical device sectors also utilize this technology for surface modification to enhance performance and biocompatibility. The effectiveness of the treatment depends on factors such as the type of gas used, the plasma power, treatment time, and the material being treated.
