Document Type and Number:
WIPO Patent Application WO/2019/105168
Kind Code:
A1
Abstract:
A novel method for repairing an ancient book by deacidification. The treatment method comprises: first putting an ancient book to be treated into a closed deacidification repairing device; dehumidifying and vacuumizing the system after the device is sealed so as to keep the system dry; after the system stays stable under negative pressure, starting a fan set (4), directly introducing nano-scale alkaline deacidification powder into the deacidification repairing device by means of a gas pipeline (15), or atomizing an alkaline deacidification solution by means of an ultrasonic atomizer (14) first and then introducing the atomized solution into the deacidification repairing device by means of the gas pipeline (15), so as to enable said ancient book to absorb the alkaline deacidification agent fully and uniformly, and at the same time, monitoring the pH value and humidity of the ancient book. Thus, deacidification repairing of the ancient book is implemented.
