Abstract
The article presents a method of experimental studies of changes in the density of birch and pine wood under the influence of various acidic environments. Graphs of changes in wood density with different impregnation periods with acetic, lactic, and hydrochloric acids are plotted. Changes in the density of solid birch and pine wood samples depending on the impregnation period are compared. It was found that the acidic aggressive medium increases the density of all the studied samples, but at different rates.
During 28 days of acid impregnation, the density of solid wood increased from 1.4 to 1.9 times, depending on the type of wood and the influence of a certain acidic environment.
