Porovnání kvality lepeného spoje v závislost na druhu spojovaného materiálu při plazmatické úpravě dřeva

The work concerns in modern surface treatment, such as cold plasma. The main aim of this work was to find out the effect of plasma treatment on the surface of wood applied before glue treatment which is influential in final quality of glueing. The work compares the firmness of glued joint of solid wood-fibre slab -- HDF and locust tree on groups of samples of treated and non-treated surface in different plasma discharges. The first part of the work comprises a summary of knowledge in the plasma field and glueing and it attempts to establish a general overview of present development in research in the field of examined issue. The second part of the work deals with method of performed experiment according to the researched norms. Results of the work have proven that plasma preparatory treatment influences the firmness of glueing and at a certain type of use of plasma discharge we can improve the quality of glued joint
