dampsorpsjon

Dampsorpsjon, also known as moisture adsorption, refers to the process in which a material absorbs water vapor from the surrounding air. When exposed to humid conditions, molecules of water are drawn into the material's microscopic pores or into its chemical structure, reducing the amount of moisture present in the air. This phenomenon is widely used in various industries such as construction, packaging, and food preservation. For example, silica gel packets that keep items dry rely on damp sorption to trap moisture. In building materials, gypsum and fiberboard can absorb and release moisture, influencing indoor humidity levels and potentially affecting thermal insulation performance. The rate and capacity of damp sorption depend on the material’s porosity, chemical composition, and temperature. Scientific studies often measure sorption isotherms to quantify how much moisture a material can hold at different relative humidity levels. While damp sorption helps control moisture, it can also lead to problems like mold growth or material degradation if not properly managed. Therefore, understanding damp sorption is essential for designing buildings, selecting packaging materials, and preserving moisture-sensitive products.
