[0002] Paper artifacts, such as ancient books, archives, documents, and books, serve as crucial carriers of history and culture, carrying a wealth of historical information and cultural heritage. However, paper is susceptible to various factors during production and use, including acidification, contamination, and wear, which can cause it to age, yellow, become brittle, and even break, severely impacting its shelf life and reading value. Deacidification and restoration are crucial technologies in the preservation of paper artifacts. Deacidification aims to remove acidic substances from paper, slowing the acidification process and thereby extending its shelf life.

[0003] During restoration, books usually need to be placed in a vacuum container for processing. The lid and the container body of the vacuum container are usually sealed with an ordinary O-ring. The O-ring is sealed by applying pressure to the lid. However, the lid is often not tight and is prone to wear, which affects the vacuum pumping of the container.

[0004] In view of this, research and improvement are carried out on the existing problems, and a deacidification repair machine sealing component is provided, aiming to achieve the purpose of solving the problem and improving the practical value through this technology. Utility Model Content
