Usage of Nanoparticles in Consolidating Painted Wooden Ceilings

Abstract

Wood ceilings with colorful decorations are one of the distinctive architectural characteristics of Islamic homes. Islamic architecture used wood widely in building ceilings, so that they are built in the form of prominent wood beams interspersed with a low area called the truss, provided that they were decorated with plant or engineering units that could be colored or gilded. In addition, ceilings were often inscribed in the middle with colorful decorative light lanterns. Despite the heritage and aesthetic values of these ceilings, most of them, if not all, are exposed to many factors and conditions that caused their deterioration discoloration. One of the topics presented for research and discussion is how to find the best materials and methods that can be applied for the treatment and consolidation of these valuable colored decorations. In light of the recent scientific revolution of the success of Nano-scale applications that have been addressed in most areas of science and technology in addition to the field of restoration, the research aims to try using nanotechnology so that the nanometer sized materials can be obtained and used in the treatment and consolidation of the colors applied to wood ceilings. Therefore, this paper aims at applying the Nano technology, specifically (Primal AC33/TiO2 nanoparticles), practically to the field of restoration in terms of treating and consolidating deteriorated colored wood ceilings. Primal AC33 5% is applied with TiO2 Nano compounds to consolidate the color layers on the wood ceilings. Then, their physical, mechanical and optical properties are evaluated after the applying the aging processes. The results concluded that the compound (Primal AC33 / Nano TiO2) can be considered as a new factor in the field of preserving color layers of wood surfaces.
