Evaluation of the resistance of adhesive joints of carpentry to atmospheric fluctuations

Wood and wooden glued products are widely used as building structures in various construction industries that operate within a wide range of atmospheric factors require stability durability. Therefore, the goal was to conduct experimental studies determine adhesive bond window element made wood under influence temperature moisture static fluctuations. In this regard, comprehensive approach applied experimentally establish effectiveness layer by investigating resistance destruction when changing humidity fields range. According values boundary after exposure such wood, it established best result tensile strength (0.29 N/mm2) obtained for polyurethane adhesive. For rubber glue PVA, 0.17 N/mm2, which provides adhesion quite well due its properties. This is fact composition must have sufficient elasticity allow expand dry out temperature. turn, based on bustilate liquid glass, has set at preasure 0.07 N/mm2 0.12 accordingly. A decrease capacity low-temperature level, loses The glass-based an alkaline environment interacts with components resin acids, reducing adhesion. results selecting effective adhesives production composite materials from depending operating conditions, provide properties
