INVESTIGATION OF PHYSICAL AND MECHANICAL CHARACTERISTICS CHANGE OF PINUS NIGRA AND ITS USE WATER COOLING TOWERS

Abstract

The aim of this study is to investigate the effectiveness of Wolmanit-CB and Protim WR230 as wood

preservatives for water cooling towers. Scotch Pine (Pinus nigra) 2x2x30 cm dimensions specimens were

prepared and placed to water return system on water cooling tower and impregned. Duration of exposure to

return water of cooling tower was 9 months. Specimens were tested for bending strenght and compression

strenght parallel to grain.

As a result, there was no rottenness or any odour observed on the specimens terated with preservatives.

However, for the control specimens significant color change, odour and surfacae softenning was observed.

According to the results of compression tests parallel to the grain and bending tests, there was a significant

strenght loss on control specimens.
