Determining the resistance of paint films due to the thickness and number of layers
Ježek, Jan ; Bomba, Jan (advisor) ; Pánek, Miloš (referee)
In the theoretical part of this work there is described the theory of coating substances: sorts of coating substances, making a coating (paint) film and requirements of coating matters. In the practical part there was being found an affect of cold liquids upon concrete coating substances, an affect of the thickness of the coating film upon the resulting surface resistence and an affect of wood upon the quality of the coating. No difference of film quality of coating substances applied to conifers and leafy wood was evidenced. The quality of coating was applied to plawood materials where pores of the upper veneer were filled with paste and so there was no difference between conifers and leafy wood. According to statistics there is no important affect upon the film quality. The coatings 80 and 150g/m2 were used, which are the limited statements of an interval recommmended by producers and the quality of coating is declared. The result: the most aggressive liquid was remover, then plum brandy, Savo liquid, vinegar and mouthwash. Jar, the preparation for washing dishes, was the least aggressive.
