With Parylene coating technology, the entire book can be reinforced and protected without having to disassemble it, and each page can be effectively protected. At present, the precious archives and materials collected by the Nanjing Museum have adopted this coating protection technology. In recent years, this technology has attracted the attention of many western developed countries, and has been applied to the reinforcement and protection of cultural relics.
1.Parylene deposition process
Parylene uses a vacuum vapor deposition process to vaporize the solid powder first, then crack it at high temperature, and then polymerize it into a high molecular polymer in a room temperature deposition chamber, which is deposited on the sample to be protected to form a protective film. The deposition polymerization is carried out at room temperature. The film is transparent, does not damage the handwriting of ancient books, and does not generate shrinkage stress. It can strengthen and protect paper, archives and books almost without changing the original appearance. The anti-aging performance of Prylene coating technology is also very good. The paper reinforced and protected by Parylene can prolong the service life of cultural relics.
2. Features of Parylene coating
Parylene is prepared by a unique vacuum vapor deposition process, and a fully conformal polymer film coating (commonly known as: conformal coating, conformal coating, Conformal Coating) is "grown" on the surface of the substrate by active small molecules. ), it can be applied to a variety of surfaces, including sharp edges, crevices and interior surfaces. This 0.1-100 micron thin film coating prepared by room temperature deposition has uniform thickness, dense and pinhole-free, transparent and stress-free, no additives, no damage to the workpiece, excellent electrical insulation and protection, and good physical properties. Mechanical properties, it is a tough, self-lubricating and uniform polymer coating material.
