Kaitsetöötlus
Kaitsetöötlus refers to the process of treating materials, particularly wood, to protect them from damage caused by biological factors such as fungi, insects, and marine borers. This treatment is crucial for extending the lifespan and structural integrity of wooden products, especially those used outdoors or in contact with moisture. Common agents used in kaitsetöötlus include copper-based compounds, such as copper sulfate or copper azole, which are toxic to wood-destroying organisms. Other preservatives might involve boron compounds or organic biocides. The treatment is typically applied through pressure impregnation, where the preservative is forced deep into the wood under high pressure. This ensures thorough protection throughout the material. Surface treatments, like dipping or brushing, are also used but offer less comprehensive protection. The effectiveness of kaitsetöötlus depends on the type of wood, the intended use, the concentration of the preservative, and the application method. Treated wood is widely used in construction for applications like fences, decks, railway sleepers, and utility poles. Regulatory bodies often set standards for the types of preservatives and their concentrations to ensure environmental and health safety.
