To perform deacidification treatment on precious manuscripts of famous scientists as Qian Xuesen, Guo Yonghuai, An Jiguang,
In July, 2020, Reli Heritage Preservation Technologies Ltd. Sent out a working team to China Aerodynamics Research and Development Center. To perform deacidification treatment on precious manuscripts of famous scientists as Qian Xuesen, Guo Yonghuai, An Jiguang, Yue Jialing, Zhang Hanxin, Zhuang Fenggan, etc. The deacdificaition job was successfully done with advanced technology from famous American brand, Bookkeeper. The verification tests show that after deacidification, pH values of manuscripts have been raised to the range of 7.5-8.5, which greatly remedies the acidification situation according to archive conservation standard DA/Z64.4-2018. The conservation life expectation of manuscripts are tremendously prolonged, which is a result highly acknowledged by officers from CARDC.
