Wood treatment involves the use of various agents and products to prolong its lifespan and enhance its properties against external agents such as moisture, rain, and sunlight. The basic system includes a mixing tank to dilute the salts in water, a storage tank for the solution, and the autoclave where the wood undergoes a vacuum and pressure process. Additional tanks can be added in parallel to the autoclave to perform multiple treatments and treat different types of wood. For this purpose, an automatic interior washing system is included in the autoclave to facilitate cycles of impregnation with different treatments, preventing them from mixing with each other. Impregnation products typically consist of water-based solutions with a concentration of copper salts. The treatment to be applied depends on the intended use of the wood. THE BASIC TREATMENT CYCLE CONSISTS OF: 1 – Initial vacuum: The air is removed from inside the autoclave and from the wood cells by applying vacuum. 2 – Filling with impregnation solution: the solution stored in the tank is transferred to the autoclave under vacuum. 3 – Pressure: pressure is applied inside the autoclave to ensure that the solution permeates the entire surface of the wood. 4 – Discharge of the solution: the pressure in the autoclave is released, and any excess solution is transferred back to the storage tank using vacuum. 5 – Final vacuum: vacuum is applied again in the autoclave to reduce the moisture content of the wood before its removal. 6 – Cleaning: Once the wood has been removed from inside the autoclave,the autoclave walls can be automatically cleaned by applying water under pressure.
