Vacuum drying

Vacuum drying is a process in surface technology that is often used to remove moisture or solvents from materials. In this process, the material to be dried is placed in a vacuum chamber in which the pressure is reduced to create a vacuum. By lowering the pressure, the boiling point of the water or solvents is lowered, allowing them to evaporate at lower temperatures. The vaporized water or solvent is then extracted, effectively drying the material.

Vacuum drying offers several advantages in surface technology. Firstly, it enables gentle drying at low temperatures, which is particularly important for sensitive materials that could be damaged at high temperatures. In addition, the vacuum process enables efficient removal of moisture or solvents from the pores or structures of the material, resulting in more even and thorough drying. This is particularly important for coatings or materials where uniform drying is critical to the quality and performance of the end product.

In surface technology, vacuum drying is often used in the production of paints, coatings, plastics and other materials where precise drying is required to achieve the desired properties. It is an important step in many production processes to ensure that the materials produced meet the required quality standards and offer optimum performance.
