Abstract

The article developed a technique for accelerated aging of wood in a climatic chamber, which simulates the operating conditions in certain classes of service conditions of wood impregnated with protective agents with confirmation of the preservation of protective properties in relation to mold, wood-coloring and wood-destroying fungi. A program for imitation in laboratory conditions of XIV–XVIII classes of wood service in accordance with GOST 20022.2–2018 has been proposed. It has been shown that under these conditions, the most effective protective agent against mold, wood-coloring and wood-destroying fungi is shale oil. However, shale oil contains a number of toxic substances with an unpleasant odor.

It has been established that a water-soluble inorganic agent based on copper triazoles in the XV, XVII and XVIII (tropical climate) service classes according to the protective ability is classified as effective, in the XVI and XVIII (subtropical climate) – ineffective.

A protective water-soluble inorganic agent based on copper triazoles and containing ammonium groups in the XV–XVIII service classes in terms of protective ability, according to test results, is classified as effective. The durability of wood impregnated with protective agents has been confirmed after 64 test cycles in a climatic chamber, corresponding to an 8-year service life.
