Embodiment 1

[0026] Embodiment 1 paper cultural relic mildew spot cleaning method

[0027] (1) Preparation of mildew spots on paper cultural relics

[0028] Potato Sugar Agar Medium (PDA): Wash and peel potatoes, cut 200g into small pieces, add appropriate amount of water, boil for half an hour, filter with 8 layers of gauze, add 10g of agar powder and 20g of glucose to the filtrate , and finally make up 1000mL of water, sub-package, sterilize, pour plate, spare liquid medium and solid medium composition formula is the same, without agar powder.

[0029] Mildew spot samples of paper cultural relics: cut late Qing rice paper 6cm×10cm, spread it on a petri dish after sterilization, spray the spore suspension of Penicillium chrysogenum on the rice paper surface with a sprayer, and cultivate it in an incubator for 10 days. During the cultivation and reproduction period, spray sterile distilled water every 12 hours, take it out after a good plaque is formed, gently treat the surface mycelium w...

Abstract

The invention relates to a method for cleaning mildew on paper relics. A technical scheme is as below: fixing a paper sample with mildew between two pieces of glass, soaking the sample in a mildew enzyme cleaner for paper relics at 20-40 DEG C for 15-90 min, then removing the residual cleaner by a siphon method, and naturally drying. The method has good cleaning effect on paper sample with mildew; the treated paper has whiteness improved by 5.58, glossiness improved by 0.33, and pH value increased to 6.82, and the tensile strength decrease has no significant change compared with the index in traditional distilled water cleaning.

Description

technical field [0001] The invention relates to a method for cleaning mildew spots on paper cultural relics. Background technique [0002] Paper cultural relics are the carrier of Chinese culture, carrying the genes of the cultural origin of the Chinese nation, and at the same time witnessing the historical changes of China, with extremely high historical value. However, with the passage of time, most of the paper cultural relics have been damaged to varying degrees, and mildew is one of them. At present, methods such as physical chemistry are used at home and abroad. Although they have certain effects, the oxidation is relatively serious, which brings adverse effects on the long-term preservation of paper cultural relics. Contents of the invention [0003] In order to solve the above problems, the present invention provides a method for cleaning mildew stains on paper cultural relics with biological protease as the main component of mildew stain cleaning agent, which has...
