METHOD FOR PREPARATION OF PLANKS TO THEIR NATURAL DRYING Russian patent published in 2001 - IPC

FIELD: process of drying of wood, mainly of heart planks, may be widely applicable at wood- working plants in production of planks, furniture, houses, etc. SUBSTANCE: prior to drying, heard planks are subjected to preliminary preparation by closing their ends and seams with an aqueous emulsifying agent possessing adhesion with raw wood. The so prepared wood and then dried by the natural method is nonhydroscopic, since it does not absorb moisture from ambient air. The method was tested on wood of the following species: pine, fir, oak, larch, maple, and cedar. The plank drying time for all the above species was on the average by 2 to 4 times shorter as compared with the traditional natural method for drying. The water content in the above species attained in the process of preparation and further natural drying did not exceed 6%. EFFECT: reduced time and enhanced efficiency of drying. 1 dwg
