Zusammenfassung:PRESSURE IMPREGNATION OF WOOD POLES FOR PRESERVATION A treatment for wood poles, as used for telecommunications and electric power poles, to reduce surface hardening comprises modifying the standard treatment solution by the addition of a polymer of ethylene oxide. A surface active agent is a further possible additive, and reduction of the hexavalent chrome ion in the standard solution is a further modification.
