This thesis is focused on the effect of glue to bonding strength at DTD-L and ABS edge for increased moisture and heat interaction. This problems is concerned not only furniture, which is located in rooms with increased moisture, as are bathrooms and kitchens, but also furniture, which is exposed to these conditions in logistics during transport, storage etc. In this regard selection of right glue has a great impact on produce quality. This work is divided into two parts, theoretical and practical. There is description of methodology and formal view of problematics in the theoretical part. Experimental measurement of temperature and moisture conditions in interior and exterior are introduced in the practical part. Surface material DTD-L was used in practical part, when was tested strength of glued joints with using PUR adhesive. The samples were burden with increased moisture 90 % and 70 % and with temperatures from 25 ° C to 80 ° C. Subsequently was tested strength of gluent joints with using method of angle pressure shear angle-wise 45 ° and a peeling method angle-wise 90 °. The results were processed, analyzed and evaluated.

Submitted diploma thesis deals with the influence of the adhesive base to quality of veneered furniture parts and follows the requirements of applicable standards for testing. The most frequently used materials in furniture were selected to verify the quality. As substrate samples were chosen 18 mm thick chipboards and as a decorative material were chosen beech veneers with a thickness of 0.6 mm. To test the suitability of adhesive compositions for veneering furniture components were selected adhesive mixtures based on condensation adhesives types (urea-formaldehyde and melamine-urea-formaldehyde adhesives) and dispersion (PVAc), and the resulting adhesive compositions were made from various types of adhesives in specified ratio (60 : 40, 75 : 25 and 85 : 15). The test samples were veneered with the same adhesive coating, which was 150 g/m2. Individual test samples were divided into groups according to the type of used adhesive, pressing temperature and pressing time. These test samples were tested after completion of the adhesive file, compression and conditioning. Quality of furniture parts was assessed in terms of physico-mechanical properties of the finished surface quality of furniture components after the completion of the surface treatment of the test samples with spraying by water-based and acrylate-polyurethane coating. The result of this thesis is the determination of depending of adhesives types to quality of veneered furniture parts. Another result is comparing of different finishes types to quality of veneered furniture parts.

This master thesis deal with the glued joint. Teoretical part is focused on basic facts and an advanteges or disadvanteges of this technique. A large part is devoted to theory of gluid process, adhesion, cohesion wettability of glued surfaces. Last part of the theoretical part is searches in the field of tension glued joints and methods to quality assessment of made joint. Experimental testing glued surfaces was made as bend test. During testing was monitored the acoustic emissions. The emissions characterize violation of glued joints. Results of this experiment are evaluated in the end of this thesis.

The thesis deals with the influence of mixture of the mixed adhesive and dispersion PVAc adhesive for bonding strength in shear strength. For the testing were selected two economically very important wood species (the spruce and beech wood) which are used in construction, furniture and building industry. All samples were grouped by the type of adhesive and by the temperature used for 28 days conditioning. All samples were bonded with coating 120 g/m2. After bonding, pressing and conditioning to required temperature were all samples subjected to a test, which examines the bonding strength in shear. The thesis deals with the comparison of the results and examines the effect of the adhesive mixture to bonding strength.

This dissertation thesis deals with the influence of temperature on the strength of the bond on furniture parts edges from exotic wood and particleboards furniture parts for the side panels. This theme covers the furniture that is during storage and transport exposed to high temperatures. It significantly affects the strength of glued joints with hot melt adhesives. This makes it necessary to pay attention when selecting the adhesive. It must withstand not only high but also low temperatures that occur during transport furniture. The practical part is focused on the problems of thermally stressed connections between the chipboard and furniture edge from exotic wood. Samples were edged by melt adhesive based on EVA copolymers, and polyurethane-based adhesive. Test samples were subjected to cyclic thermal loading that simulated conditions of the internal environment of the transport unit. Testing was used examinations peel and oblique pressure skid. The output data from these tests were evaluated between themselves and compared with edge finished by ABS edge. As a supplementary method was also used bending test, that examined the size of the internal stress in the veneer edge

This study aims to compare the strength of bonding joint and bonding quality depending on the proportion of violations. The first part contains a research of various types of adhesives. Based on the research, two types of adhesive were chosen - the PVAC and UF adhesives. These adhesives are used directly in manufacturing of solid wood panels. Our test samples were made of beech wood and oak wood using both types of adhesive, four groups of samples altogether. The thesis contains an analysis of the requirements for bonding strength as well as production of samples from solid wood panel. According to current standards, the tests were performed to determine the density, moisture content, strength of bonding joint, the bonding quality and proportion of violations.
