The Evaluation of Reinforcement Effect on Reinforcing Haimenkou Sites Water Archeological Wood with Phenolic Resin

Reinforcing 60 Haimenkou sites water archeological wood with natural resins (hydrogenated resin and bleached shellac), determining the reinforcement shrinkage, physical and mechanical properties, surface contact angle, formaldehyde emission, antiloss and so on, comparing the evaluation indexes of reinforcement archeological wood with unreinforcement archeological wood′s and modern health wood′s.The results show that the color of reinforcement archeological wood is light redbrown. The average horizontal reinforcement shrinkage is 914%, the average vertical reinforcement shrinkage is 417%. The basic density increased from 016g/cm3 to 029g/cm3. The compressive strength parallel to grain increased from 367MPa to 1670MPa. The surface contact angle of the three facets increased significantly, which show the hydrophobicity of reinforcement ancient is enhanced significantly. The formaldehyde emission with perforator method is 1915mg/100g, so the storage conditions of reinforcement archeological woods are should be sealed. The mass loss rate in water loss test is 547%, which illustrate most of the phenolic resin in the specimen is fixed in the archeological wood. In summary, the indicators of reinforcement archeological with phenolic resin are significantly improved,which can meet the following transport, storage and exhibition.
