METHOD FOR TREATMENT OF CREOSOTE IMPREGNATED WOOD TO SUBSTANTIALLY REDUCE OR AVOID BLEEDING

摘要

The invention relates to a method for treatment of creosote impregnated wood in order to substantially reduce or avoid bleeding, the wood being treated with air at a pressure above atmospheric before impregnation. The method is characterized in that after the creosote impregnated wood has been stored at least until the initial air pressure has been balanced it is subjected to a heat treatment in a heat medium, a vacuum being simultaneously applied.
