Treatment of Paper Oxidation and Acidification by Linseed Gel with MgHCO<sub>3</sub> and Zinc Oxide (NP)

Abstract

Collection paper in museums and libraries and stores suffer from acid hydrolysis and oxidations, many factors catalysis the deterioration by acid hydrolysis and oxidations, such as humidity and temperature and light and fungi, paper contains iron ink and colors based on ions heavy metals such as copper and zinc, air pollution, visible and industry light, Residues of manufacturing processes such as bleaching material, additives such as sizing materials, The study proposes a new antioxidants agent by using Line seed gel with magnesium bicarbonate loaded with Zinc oxide (NP), the positive impact of this treatment was evaluated on thermally accelerated ageing on cotton, linen and wooden samples, the samples was verified by FTIR, tensile strength and elongation measurement, Measurement of color change, PH measurement, aromatic hydroxylation assay, (SEM) scanning Electron microscope, Linseed gel with MgHCO 3 and Zinc oxide (NP) results to stabilize inks and stop oxidation that occurred and treatment of free radicals, the inks were most stable, The mechanical properties of the samples have been greatly improved, Linseed gel with magnesium bicarbonate loaded with Zinc oxide (NP) consolidation and treatment the samples, the zinc oxide (NP) nano oxide was observed between the fibers which works to protect the cellulose fibers From degradation.
