Abstract

U ovom diplomskom radu mjerena je reflektancija na uzorcima papira koji su bili izloženi UV zračenju i na taj način ubrzano ostareni. Navedeni uzorci nastali su u laboratorijskim uvjetima recikliranjem predhodno otisnutog papira.

Diplomski rad podijeljen je na dva dijela: teorijski i eksperimentalni dio.

Teorijski dio govori općenito o prirodi svjetlosti i raznim teorijama koje su se razvijale kroz povijest, o spektru elektromagnetskih valova te o interakciji svjetlosti s materijom. Također su opisana i optička svojstva papira te procesi reciklacije i starenja papira.

U eksperimentalnom dijelu nalaze se opće karakteristike spektrofotometrije kao i opis uređaja koji je korišten prilikom mjerenja pojedinih uzoraka – spektrofotometra. Također su detaljno opisani i specificirani mjerni uzorci. Rezultati mjerenja dani su u obliku spektrofotometrijskih krivulja.

Abstract (english)

In this graduation thesis measuring of reflectance are made on paper samples that were exposed to UV radiation and thus rapidly aged. The aforementioned samples were created in laboratory conditions, recycling of previously printed paper.

Graduation thesis is composed of two parts: theoretical and experimental part.

The theoretical part describes nature of light and different theorys during the course of history, about spectrum of electromagnetic waves and interaction of light and surfaces. Optical features of paper and processes of paper recycling and ageing have been also described.

In the experimental part there are general characteristics of spectrophotometry and the description of the spectropfotometer, the measurement apparatus used for measuring of particular samples. The thesis also includes a detailed description and specification od the measured samples. The measurement results have been presented in spectrophotometric curves.
