The aim of this diploma thesis is a study and description of a mutual interaction of solvents belonging to the green solvents group, specifically glutaric acid esters and selected acrylic and alkyd coating systems. In the experimental part of this thesis there is a study of a resistance of the coating systems to solvents by the spotting method, which is subsequently then combined with an adhesion experiment of the coating film by the cross-cut test. Those experiments are made according to matching methods in valid version.

This thesis is aimed at a very detailed process of a transparent plexiglass used for manufacturing an upstand of a gramophone. The diploma work is mainly focused on various types of the plexiglass, its attributes and the gramophone’s upstand production. Several manufacturing technologies of a plexiglass such as division of a board-type semi product, precise milling, grinding, polishing and thermal treatment are provided in this diploma work through a very detailed description of a production process of a gramophone’s deck. The outcome of this thesis is a description of individual technologies and the economic evaluation within the real business environment of AZ Plastik company.
