Abstract: FIELD: methods of production of plywood. SUBSTANCE: veneers are preliminarily dried up to moisture content of 6.0 to 8.0%, and then, placed in metal container which is used for better preservation of magnetic induction in the process of impregnation of veneers with magnetic water. Magnetic water impregnates the cells of wood veneers to increase the cell hollows. During cementing, cement well penetrates into all anatomic elements. Veneers are impregnated with magnetic water for 48 h. Water is magnetized with the aid of D.C. electromagnetic apparatus or device SO-3 (orchard and garden type). Tap water is let stand for three hours for volatilization of all harmful gas impurities and then, passed up to five times through permanent magnet. After impregnation in magnetic water, wood veneers are dried again and cemented into plywood. Veneers which are not used for cementing are not subject to treatment with magnetic water, and those which are subject for cementing are passed through cementing bench two times for filling all cavities with cement. Plywood with magnetized veneers offers high strength and differs from the common plywood in that it may be used in form of guard structures of heated and nonheated buildings and structures, in form of wall boards, covers and floors, solid doors and panels, and also in form of load-bearing structures of beams, arches, frames, pillars of bow-screen domes and parquet floors. Magnetized plywood is distinguished by higher density, compression, tension and bending strength, reduced moisture and water absorption, and increased static and impact hardness. EFFECT: improved mechanical and physical properties due to treatment of wood veneers with magnetic water. 3 cl
