Method for preparing seriously contaminated antique silk substitution sample

Abstract

The invention discloses a method for preparing a seriously contaminated antique silk substitution sample. The method comprises the following steps of: A) putting commercially available habotai and a rusty iron product together in a humid environment for 10-15 days so that the commercially available habotai is stained with rust; B) soaking the commercially available habotai stained with rust in fresh pig blood for 12 h and then putting in a mixture of pig meat and pig liver according to a weight ratio of 1: (20-50), and standing for 5-7 days at a cool airtight place, wherein the mixture contains pig fat, pork lean, pig liver and water in a ratio of 2: 1: 1: 4; C) taking out of the commercially available habotai, scraping carrion attached to the surface of the habotai, performing aging treatment on the contaminated sample in a double aging way of ultraviolet rays and ozone, irradiating by means of an ultraviolet treatment box at a radiation intensity of 4000-4600 mu w / cm<2>, and simultaneously supplying ozone into the treatment box for 30 min every hour, wherein the ozone output quantity is 400 mg / h; and turning over the treated commercially available habotai every hour and treatingthe habotai for 50-80 hours. Compared with the prior art, the method is capable of simulating a cultural relic authentically, simple in operation and low in cost.

Description

technical field [0001] The invention belongs to the technical field of cultural relics protection, and in particular relates to a preparation method of a heavily polluted silk cultural relic substitute sample. Background technique [0002] Silk is an important element of Chinese civilization. As an indispensable and important carrier for the study of ancient civilization, silk cultural relics have great historical value, artistic value and scientific value. [0003] Due to the long-term burial in the ground or the influence of various factors, many unearthed silk cultural relics have been seriously polluted and damaged, such as the pollution of organic substances such as blood fat proteins decomposed by corpses, and the rust pollution caused by iron tools in the buried environment. When cultural relics protection workers clean silk cultural relics, it is often difficult to clean due to complex pollutants, serious pollution, and low decay intensity of cultural relics, and eve...
