[0003] 1. Microform: The duplication of documents is a regenerative protection measure for documents, but even documents that are too brittle to be flipped cannot be microformed, and this microform method can no longer maintain the original features of ancient books
[0004] 2. Deacidification reinforcement: deacidification is an important measure to delay the aging and deterioration rate of books and documents, but the current deacidification method has problems such as high cost, complicated operation and environmental pollution.
[0005] 3. Wire mesh reinforcement: its main disadvantages are that the repair rate is too low, the workload is too large, and the service life is not long
[0006] To sum up, the known protection and reinforcement methods for ancient books and documents are difficult to meet the current increasingly urgent requirements for the rescue of ancient books and documents of the Republic of China due to the reasons of technology and materials.

Embodiment 1
[0035] The parylene surface coating process of ancient books and documents includes the following steps:
[0036] 1. Put the p-xylene raw material in the evaporation boat in the evaporation chamber;
[0037] 2. Clamp the books or documents to be coated on the book expansion bracket in the polymerization deposition chamber, and close the vacuum bell jar;
[0038] 3. Open the throttle valve, turn on the vacuum mechanical pump, and evacuate the system to make the vacuum degree of the system below 10pa;
[0039] 4. Raise the temperature of the cracking chamber to 600°C, open the cold trap, and make the temperature of the cold trap below -80°C, and then heat the evaporation chamber to steadily increase the temperature of the evaporation chamber to 120°C. When the temperature of the evaporation chamber exceeds 90°C, adjust the throttle valve The pumping speed is to keep the vacuum degree of the sedimentation chamber at 20pa. At the same time, start the transmission motor to make th...

[0046] The parylene surface coating process of ancient books and documents includes the following steps:
[0047] 1. Put the p-xylene raw material in the evaporation boat in the evaporation chamber;
[0048] 2. Clamp the books or documents to be coated on the book expansion bracket in the polymerization deposition chamber, and close the vacuum bell jar;
[0049] 3. Open the throttle valve, turn on the vacuum mechanical pump, and evacuate the system to make the vacuum degree of the system below 10pa;
[0050] 4. Raise the temperature of the cracking chamber to 700°C, open the cold trap, and make the temperature of the cold trap below -80°C, and then heat the evaporation chamber to steadily increase the temperature of the evaporation chamber to 125°C. When the temperature of the evaporation chamber exceeds 90°C, adjust the throttle valve The pumping speed is to keep the vacuum degree of the precipitation chamber at 40pa, and at the same time start the transmission motor to make...

Abstract
The parylene surface coating equipment and coating process for ancient borrowed books and documents of the present invention relate to the gas phase deposition coating process and coating equipment for the reinforcement and protection of parylene on the surface of ancient borrowed books, archives, documents, etc. . The structure of coating equipment includes evaporation chamber, cracking chamber, polymerization deposition chamber, cold trap, throttle valve, vacuum mechanical pump and refrigerator. The coating process is to put the p-xylene raw material in the evaporation boat of the evaporation chamber; clamp the books or documents to be coated on the book expansion bracket of the polymerization deposition chamber; vacuum the system to make the vacuum degree of the system below 10pa Raise the temperature of the cracking chamber to 600°C-700°C, open the cold trap, reheat the evaporation chamber, adjust the pumping speed of the throttle valve, keep the vacuum degree of the precipitation chamber at 20-40pa, and start the transmission motor at the same time to make the book unfolding bracket rotate, The p-xylene gas generated by the evaporation chamber enters the cracking chamber, enters the polymerization deposition chamber through the gas splitter, and is coated on the surface of the rotating book or document.
Description
technical field [0001] The parylene surface coating equipment and coating process of ancient books and documents of the present invention relate to the vapor deposition coating process of parylene (Parylene) reinforcement and protection on the surface of ancient books (rare books), archives, documents, etc. and its coating equipment. Background technique [0002] According to the research and analysis of the current situation of the paper aging and deterioration of the books and documents collected by the National Library of my country, it can be seen that the books, newspapers and periodicals and other documents in the collection of books and periodicals in my country are currently in a relatively serious state of aging, especially the paper aging of documents before the 1940s is particularly serious, and some It is no longer possible to carry out circulation and borrowing. If rescue measures are not taken in time, irreparable losses will be caused. In February 2004, the Anc...
