Abstract

Diplomski rad sastoji se od teorijskog i eksperimentalnog dijela.
U teoretskom dijelu rada pobliže je objašnjen sastav premaza, njegovo djelovanje na površinu i vrste premaza. Također, prikazan je pregled metoda zaštite od korozije, te su detaljnije prikazani neposredni troškovi uzrokovani korozijom. Detaljnije je opisan protupožarni premaz za zaštitu čeličnih konstrukcija te je obrađen sustav zaštite protupožarnim premazom. Primjerom zaštite pasivnim protupožarnim sustavom na školskoj dvorani dan je realni prikaz izračuna faktora profila i debljine suhog filma protupožarnog premaza za klase otpornosti R30 i R60.
U eksperimentalnom dijelu rada provedena su ispitivanja debljine premaza, ispitivanja u slanoj komori, ispitivanja u vlažnoj komori, ispitivanja prionjivosti, ispitivanja vatrootpornosti te ispitivanja prema normi ISO 4628. Cilj ispitivanja bio je utvrditi otpornost protupožarnog premaza na otvoreni plamen nakon izlaganja korozivnim uvjetima ovisno u sustavu antikorozivne zaštite koja se primjenjivala u sustavu sa protupožarnim premazom. Svaki uzorak je premazan temeljnim premazom, vatrootpornim premazom i završnim premazom. Ispitane su dvije skupine uzoraka, jedna klase otpornosti R30 i jedna klase otpornosti R60.

Abstract (english)

This graduate thesis consists of two parts: theoretical and experimental.
In theoretical part of the thesis, the definition of coatings and its effects on the surface is explained more precisely. Also, an overview of the corrosion protection and costs caused by corrosion is given. A fire protection coatings are explained more detailed and one example of fire protection on steel construction is given. Example of passive fire protection on school hall gives a realistic view of the profile factors and the thicnesses of dry film of the fire resistance coatings for R30 and R60.
In experimental part of the thesis, dry film coating thickness are measured. Tests in the salt spray and humidity chamber are concluded. Adhession test with Pull-off method, fire protection test were carried out and examinations according to the ISO 4628. Each sample is coated with a primer, fireproof coating and finish coat. Two groups of samples are tested, one with the fireproof resistance class of R30 and with the fireproof resistance class R60.
