Vliv pružnosti a pevnosti nátěrového filmu na užitné vlastnosti povrchových úprav dílců ze zadýhované DTD
Symerská, Andrea
The submitted thesis issolve deffect elasticity and strengthof a paint film on usable properties surface treatment specifically on work piece sofveneered chipboard and on inertsubstrate UP foil. On foil and chipboard' ssamples were painted nitrocellulosela cquer, water borne lacquer, UV curing lacquer a twoo polyurethane lacquer. Lacker were jugged on physical and mechanical properties by standards and experimental testing. There sultis the evaluation underlying effect elasticity and strength of a paint film on usable properties surface treatment.

Odolnost povrchových úprav vůči poškrabání
Samiecová, Kateřina
This bachelor thesis exames the resistance of surface finish against scraches. The main focus is to analyze the stress of the surface finishes, mainly done by scratching, cutting and hitting. In theoretical part, certain requirements for surface finishes are described. Also there is explained the method of application. There is also analysed their composition and upcoming formation of the film. The main aim was to determined resistance of certain surface finishes against various types of scraching, or demaging the surface of the finish and identify the impact of finishing various types of veneers on the resistance of the surface. There has been also verified if each exam can be replaced by another. Veryfing exames was according to valid standarts.

Vztah pevnosti nátěrových filmů a vlastnosti povrchových úprav
Večeřová, Michaela
The bachelor´s work deals with coating endurance relation and surface finishing properties. The aim of the work is to determine climatic and weather influences relation to durability of wooden garden furniture surface finishing. The theoretical part analyses requirements on surface finishing of wooden garden furniture. It also dissects surface treatment characteristics as well as weather effects influences and the quality of finishing treatment. The practical part deals with solving procedure of examined coating formulas being applied on polyester and wooden base. They were sequentially exposé to particular climatic conditions and then after a certain period examined from the stronghold and physical-mechanical point of view. The experimental measurement proceeded in accordance with standards and experimental methods for surface treatment testing. The benefit of the investigation is learning about the relation of climatic changes and weather conditions to stronghold characteristics and physical-mechanical qualities of surface finishing. The relation between the coating characteristics and the surface treatment has been found.

Vliv exteriéru na vlastnosti nátěrového filmu
Rudická, Eliška
This thesis investigates the influence of weather conditions on the properties of the film.There was selected six kinds of tree species, which are used for the manufacturing of the outdoor furniture the most. There was a request for possibility to grow this kinds of trees in the Czech Republic. There was used five shades of color on the each tree species. Samples were tested at the laboratory before putting to the exposure and when the summer season was over, samples were tested as before. In discussion there is statistical comparison of changes which occurred on the surfaces of the samples. In the end of the diploma thesis is evaluation which are the best tree species and the best color shades for the manufacturing of the garden furniture.

Povrchová úprava stavebně-truhlářských výrobků s krátkou životnosti
Suchý, Michal
This diploma thesis deals with the design system of finishing of structural wood construction with a short lifetime and performing tests of physical and mechanical properties. The system of finishing is based on the used adhesives. Three different kinds of adhesives (UF, MUF, PVAc) were used to test. Tests were conducted by technical standards ČSN, EN, ISO and BS. The aim of the study was to determine the properties and durability of the proposed surface treatment and to evaluate the possibility of using it for practice. Tests were conducted: surface hardness, adhesion to substrates, resistance to scratching, to steam, cold liquid, falling steel ball, abrasion and attrition. Furthermore, the measured sheen, color changes and light fastness.

Odolnost povrchových úprav dřevěných podlah vůči oděru
Kupka, Jan
The work is focused on the influence of climatic conditions and resilience transparent finishes for wood flooring veneered chipboard. Properties of the coatings were tested on DTD spruce and cherry veneer. Samples prior to testing coatings were conditioned under conditions of -30°C, 23°C and 50°C
