Treatment of Ancient Wood by using Radiation Technology of Polymers


Abstract in English

The aim of the study is repairing some partially damaged archeological wood and restoration it before being completely damaged. For achieving this aim, the radiation technology was used in preparing some polymer blends such as Poly (vinyl alcohol) (PVA), Poly ethylene glycol (PEG), acrylic acid (AAC), and Acryl amid (AAm) to improving adhesion forces of polymer with wood and protecting it. The results show that the best mechanical properties was achieved by using Poly(vinyl) alcohol (PVA), acrylic acid (AAC), and acryl amid (AAm). Also, results show that by increasing the ratio of acrylic acid (AAC), the tensile strength, adhesion force, hardness, transparency, are increasing. The best tensile strength obtained was 4.79 MPa for polymer blends contains 18/% acrylic acid, 6% acryl amid, 12% poly (vinyl alcohol) when exposing to Ultra-Violet ray dose of 210 . Results, also showed that the exposing of wood to Ultra-Violet ray dose of 250 [Gry] was enough for doing sterilization, purification.
