The main objective of the master's thesis - to examine the car putty dryness under different temperature regimes, hardener content and drying time, isiaiškinti bending methods and putty chapping. Plaster drying time depends on the equipment used, and the curing time dependence of the direct influence of the drying modes addiction. Since the greatest influence putty hardener, the curing time may be varied to increase or decrease and filler solidification effective as a drying temperature of 60 degrees and a hardener points placed in terms of technologies. It was found that using the appropriate filler and hardener proportions hardened remains elastic, does not any air gaps, cracks, too late sanding and well treated. The analysis carried out showed that the addition of filler to lower the amount of hardener is not fully cured and remains fragile, soft, suveliamas sanding paper remains poor quality both treatment and further course of priming and painting process, as there is a variety of errors. Machining costs depend on the glaze preparation and putties. Botched ready for damage not just filler, but also sanding, primer and paint and time consumption. Work size - 47 p. text, 54 pictures, 6 tables. |
