Abstract

U ovom diplomskom radu načinjena su ispitivanja na fotokopirnim papirima od 7 različitih svjetskih proizvođača (Fabriano, IQ, Navigator, Pioneer, Plano Premium, rcopy i Xerox). Praćen je utjecaj neionske površinsko aktivne tvari, etoksilata masnog alkohola na optička svojstva papira. Od svakog fotokopirnog papira pripremljeno je 10 uzoraka jednake mase. Načinjene su dvije obrade papira: a) u destiliranoj vodi i b) u vodenoj otopini etoksilata masnog alkohola. Na jednom uzorku je načinjeno spektrofotometrijsko mjerenje nakon sušenja na zraku, a drugi je prvo izložen ubrzanom starenju elektroničkom lampom koja emitira vidljivo i ultraljubičasto elektromagnetsko zračenje, te su nakon toga napravljena mjerenja. Načinjeno je po 3 mjerenja spektrofotometrom za svaki pojedini uzorak. Spektrofotometrijski podaci obrađeni su u Origin 6.5 Professional programu, te su rezultati prikazani spektrofotometrijskim krivuljama. Ovisno o proizvođaču, odnosno sastavu papira pokazali su i različite rezultate na osnovu kojih je moguće odrediti svojstva, tip i kvalitetu papira.

Abstract (english)

This thesis made studies on paper from 7 different manufacturers in the world (Fabriano, IQ, Navigator, Pioneer, Plano Premium, rcopy and Xerox). The effects was monitored of non-ionic surfactants, fatty alcohol ethoxylate on the optical properties of paper. Of each photocopy paper it was prepared 10 samples of equal mass. Two processing of paper was made: a) in distilled water and b) in the aqueous solution of fatty alcohol ethoxylate. Once the sample is made spectrophotometric measurements was taken after air drying, and the other is first subjected to accelerated aging with electronic lamp that emits visible and ultraviolet electromagnetic radiation, and then made measurements. Three spectrophotometer measurements was made for each sample. Spectrophotometric data were analyzed in Origin 6.5 Professional program, and the results are shown by spectrophotometric curves. Depending on the manufacturer and parts of the paper, they showed different results based on which it is possible to determine the preferences, type and quality of the paper.
