METHOD OF TIMBER PROTECTION

摘要

FIELD: process engineering.SUBSTANCE: invention relates to timber processing and protection against biological destruction. Proposed method comprises impregnation of timber with water solution of antiseptic calcium polysulfide containing 18-27 wt % of calcium sulfide with water making the rest. Note here that used water solution of calcium polysulfide features density of 1.20-1.25 g/cmwhile impregnation consists in immersion, spraying and application by brush.EFFECT: reliable protection with minimum negative effects to environments.3 cl, 1 tbl
