Embodiment 1
[0050] Example 1: Discussion on the production process of paste containing different additives and the test of paste acidity and viscosity
[0051] 1. Experimental materials and instruments: flour (produced by Iron Man Dacheng Company); Chuanjiao (purchased from Beijing Tongrentang Wangjing Store), alum, frankincense (purchased from China Medicinal Materials Company), beeswax (purchased from Beijing Chemical Reagent Company, melting point 62°C ~67°C); phosphate standard buffer (25°C, pH6.86), phthalate standard buffer (25°C, pH4.02); NDJ-1 rotary viscometer (Shanghai Changji Geological Instrument Co., Ltd. Company); pHS-3C precision acidity meter (Shanghai Second Instrument Factory).
[0052] 2. Production of mounting paste
[0053] Through consulting ancient documents, many years of practical experience and many experiments and explorations, it is preliminarily determined that the dosage ratio of flour and water is 1:3, and the production time at 200V is 7-11 minutes. The d...
Embodiment 2
[0076] Embodiment 2, the bacteriostasis effect evaluation that contains different additive ingredients paste
[0077] The loss and damage of traditional cultural relics is very serious, and the cause of mold pollution has become an important reason for document damage. Cladosporium, Alternaria alternaria, Aspergillus flavus, Aspergillus niger, Aspergillus versicolor and other Aspergillus, Penicillium rugosa and other Penicillium and Mucor, Aspera, Curvularia lunata, Paeciliaceae are the most frequently appearing in cultural relics Mildew, bulbous hair shell, Fusarium and so on. Through the four aspects of strain selection, inoculum control, medium selection, and in vitro antibacterial test methods, the relevant literature was summarized, and the strain selected for this test was determined to be the most common mold: Aspergillus niger; Determine the drug-based culture medium method as the test method of this test. Medicine-based medium method: According to the physiological ...
Embodiment 3
[0103] Embodiment 3, carry out screening test to alternative alum additive
[0104] Shown by the experiment of embodiment 1 and embodiment 2, alum, Chuanjiao, Radix Potatoes, frankincense, beeswax are all by its advantage in paste additive, especially the antibacterial advantage of alum is bigger, although alum can increase paste The viscosity of the paste also has antibacterial effect, but the acidity is strong, which is not conducive to the preservation of paper. Therefore, on the basis of determining the increase in paste viscosity and antibacterial effect, select a suitable additive that can replace alum, thereby increasing the acidity.
[0105] 1. Test materials
[0106] (1) Flour (Guchuan brand, 5Kg); (2) Artemisia argyi, Baibu, Chuanjiao (purchased from Shaanxi Ruikang Biological Engineering Co., Ltd.), borneol, alum, talc (purchased from Tongrentang Wangjing store); (3) Red Star brand special clean skin Shengxuan; NDJ-1 rotary viscometer (Shanghai Changji Geological I...
