What does the process of "sap displacement" in wood treatment involve?

The process of "sap displacement" in wood treatment involves replacing the wood's natural sap with preservatives. This method is significant in wood preservation as it helps to ensure that the wood is protected from decay and insect damage. By displacing the natural sap, which can provide a conducive environment for pests and fungi, the treatment allows for the infusion of chemical preservatives that penetrate deeply into the wood and create a barrier against such threats. This process is essential for extending the lifespan of wood materials used in various applications, especially those exposed to elements or high moisture environments.
