Impact of Several Impregnation Materials and Varnishes on Gases Analysis of Scotch Pine Left in The Weather Conditions

Abstract

The most objectionable environment for the wood material is outdoor conditions. This study is carried out to determine the amounts of oxygen, carbon monoxide, carbon dioxide and nitrogen oxide emitted by the combustion of wood materials, which are left in the outdoor conditions. For this purpose impregnation materials wolmanit-CB and tanalith-E, which are commonly used for wood protection, and synthetic and water-based varnishes as varnish types are studied. The results indicate that CO is emitted. It is confirmed that varnishes show a lowering effect and the impregnation materials shows an additive effect in the combustion caused by fire, combustion with flame and ember combustion phase. As a conclusion, it is observed that impregnation materials wolmanith-CB and tanalith-E and synthetic and water-based varnish types have an important effect on the gas values of wooden material occurring during the combustion.
