This method is called PVCR. It is used for processing

building structures and parts using fire retardants and antiseptics.

Description:

When impregnating using this method, a vacuum is used, which is formed as a result of the temperature difference in the wood, first by the hot liquid being heated in it, then quickly cooled.
When heated, the air increases in volume iceland mobile database is removed, while moisture evaporates.
When immersed in a cold liquid, the volume of the cooled steam-air mixture decreases, creating a vacuum in the outer layers of the wood.
The antiseptic solution penetrates the material under the influence of atmospheric pressure.
Impregnation by immersion

It is considered the most preferred method when working on construction sites, allowing wood processing without interrupting the construction process.

Description:

This method involves soaking the wood.
It is the simplest, since it requires a large container in which the material is soaked for a certain period of time.
Baths can be cold or hot, equipped with special lids, anti-floating mechanisms, allowing the material to be kept at the required depth.
The impregnation time is determined individually, usually it is about several days, during which the wood is impregnated by a couple of centimeters.
