Abstract
In modern conditions of development of a national economy wood is among the most widespread constructive materials. Also, wood traditionally occupies its niche in the production of furniture and joinery. In these industries, the bonding of wood and wood materials is the main connection. Gluing of wood is made not only to give to preparations of the demanded sizes, but also improvement of operational characteristics, and also for the purpose of economy of a material. There are different types of gluing: gluing blanks in thickness and length, gluing tenon joints, gluing boards and gluing layouts on the edges of the boards, gluing with simultaneous bending, facing with wood and synthetic materials, gluing parts of soft furniture elements. The paper investigated the influence of the type of glue on the bonding strength of wood and wood materials in modern industrial use. Adhesives based on polychloroprene, polyvinyl acetate, rubber and wood materials of different species – ash and beech-were selected for the study. The tensile strength of the adhesive joint was controlled when chipping along the fibers. most suitable for gluing pieces of wood of firm deciduous breeds in the thickness and width are adhesives based on polyvinyl acetate. Noticeable differences in the strength of freshly glued seams on beech and ash are not recorded, which is explained by their almost identical density.
