Strain processes are All those during which the treatment is completed in closed cylinders with used force or vacuum. These procedures Have a very selection of advantages more than the non-pressure methods. Generally, a deeper and even more uniform penetration and the next absorption of preservative is achieved. A different advantage is that the treating circumstances may be managed to ensure that retention and penetration could be different. These pressure processes can be adapted to big-scale generation.
