Wood preservation impregnates the wood to stabilize its dimensions, increase its resistance to water and chemicals, and reduce cracking.
The structure of wood is similar to a sponge, with cell cavities and cell walls, which represent the actual wood. Wood treatment coats these walls with preservatives to protect them from decay caused by wood-destroying fungi and insects.
The preservative penetrates deep into the wood with pressure and vacuum. The vacuum removes the air from the cavities to create space for the preservation solution. The solution is then forced deep into the wood under high pressure.
Wood treatment resists wood rotting and infestation due to soil or water, fungi, insects, and other elements. This process is widely employed in damp and excessively humid areas. To obtain maximum penetration of preservatives, vacuum is used to impregnate the wood.
While process requirements vary in the desired vacuum and capacity, the basic procedures are similar, consisting of initial vacuum, filling, application of pressure, discharging the solution, recovery vacuum, and end of a cycle.
When a leading, global material & chemical production company sought to upgrade its legacy equipment, they chose to continue their long-standing relationship with Nash.
