Infrared drying of coatings

Rad se sastoji od teorijskog i eksperimentalnog dijela. U teorijskom dijelu rada obrađeni su premazi za zaštitu od korozije te postupci njihova sušenja s naglaskom na sušenje infracrvenim zračenjem (IC). Provedena je analiza isplativosti sušenja IC-om u ekonomskom, energetskom, i ekološkom aspektu u odnosu na druge metode sušenja te je navedeno gdje se danas najčešće primjenjuje. Također, obrađena je elektrokemijska impedancijska spektroskopija kao metoda za ispitivanje zaštitnih svojstava premaza. U eksperimentalnom dijelu rada ispitani su premazi sušeni infracrvenim zračenjem i atmosferski te je cilj bio istražiti mijenjaju li se svojstva premaza promjenom načina sušenja. Detaljno je opisan postupak pripreme površine i svih odrađenih testiranja sukladno normama te su naknadno izneseni rezultati uz zaključke. Na temelju proučene literature i provedenih eksperimenata definirane su prednosti i nedostaci sušenja infracrvenim zračenjem u odnosu na konvencionalne načine sušenja.This graduate thesis consists of theoretical and experimental part. Theoretical part of thesis describes topic of coatings as a system of corrosion protection and drying, with an emphasis on drying by infrared radiation. An analysis of the cost-effectiveness of IR drying in economic, energy, and environmental aspects in relation to other drying methods was conducted and its most common applications were shown. Electrochemical impedance spectroscopy was explained as a method for testing the protective properties of coatings. In the experimental part of the thesis, coatings dried in atmospheric conditions and by infrared radiation were tested. The aim was to investigate whether the properties of the coating change by changing the drying method. The procedure of surface preparation and all performed tests in accordance with the standards are described in detail, and the results are presented with conclusions. Based on the studied theory and conducted experiments, the advantages and disadvantages of infrared drying in relation to conventional drying methods have been established
