Vrednotenje emisij delcev prahu nastalih pri procesih rezanja jekla

Bojič Burgos, Jay (author), Karpe, Blaž (mentor), Agarski, Boris (co-mentor)

V okviru diplomskega dela so bile izvedene meritve emisij delcev prahu nastale pri rezanju jekla S460 s plamenom in s plazmo. Meritve emisij delcev prahu so bile izvedene z merilnikom za osebno vzorčenje ZAMBELLI EGO PLUS TT, analizo sestave in geometrije delcev prahu zbranih na filtrih merilnika za osebno vzorčenje pa smo opravili na vrstičnem elektronskem mikroskopu ThermoFisher scientific Quattro S. Vrednotenje velikosti in oblike delcev je bilo izvedeno v skladu s standardom ISO 13322. Temeljni cilj predlaganega diplomskega dela je bila analiza emisij inhalatornih frakcij prahu v delovnem okolju pri procesih rezanja jekla s poudarkom na analizi kemijske sestave prahu, velikosti in oblike delcev.

• Title: Evaluation of the emissions of dust particles resulting from steel cutting processes

Abstract

Within the framework of this diploma thesis, measurements of dust particle emissions from Oxy-fuel and plasma cutting were made. The measurements were carried out using a ZAMBELLI EGO PLUS TT personal sampler. The analysis of composition and the geometry of dust particles, that were collected on the filters of the personal sampler, were analyzed using a typical electron microscope ThermoFischer scientific Quattro S. Particle size and shape evaluation was performed in accordance with the standard ISO 13322. The basic aim of the proposed diploma thesis was to analyze the emissions of inhalable dust fractions in the working environment of steel cutting processes with an emphasis on the analysis of dust composition, particle size and shape.
