Deacidification protection method for rubbing with concave-convex structure

A concave-convex structure and deacidification technology, applied in the post-processing of waste paper, recycling technology, paper recycling, etc., can solve the problems of damage to the concave-convex shape structure on the rubbing surface, inability to remove the inert layer of the rubbing, and unsatisfactory deacidification effect. Improve the deacidification effect, the deacidification effect is remarkable, the deacidification process is mild

Problems solved by technology

But in above-mentioned two kinds of methods, directly soaking in water-based deacidifying liquid can make the water content in rubbing too high, cause the distortion of rubbing fiber, destroy the structure of rubbing; The rubbing produces a scour effect, which damages the concave-convex shape structure on the surface of the rubbing
And the above two deacidification methods cannot remove the inert layer on the rubbing surface, so the deacidification effect is not ideal

Embodiment 1

[0029] Select acidified rubbings (rice paper material), use DC high-voltage power supply to generate plasma through dielectric barrier discharge in the plasma reaction chamber, use helium gas, the reaction voltage is 60V, and the current is 0.3A. The plasma generated by the gas discharge in the medium is brought out to generate a plasma flow. When a stable pulse current filament appears in the reaction chamber, start timing. The time for the plasma flow to process the rubbings is 3min. After the plasma treatment is completed, turn off the power. Take out the rubbings and put them in the deacidification room for later use.

[0030] First, 4wt% calcium hydroxide solution is ultrasonically atomized, and the atomized deacidification agent is passed into the deacidification chamber. After the surface of the rubbing is soaked by the atomized deacidification agent, the rubbing is taken out and placed in Dry naturally in the air, that is to complete the deacidification process of rubb...

Embodiment 2

[0047] The deacidifying agent in the embodiment 1 is adjusted to 3wt% magnesium hydroxide solution, and the rest are the same as the operation steps of the embodiment 1. The final deacidification effect is substantially the same as in Example 1.

Embodiment 3

[0049] The deacidifying agent in embodiment 1 is adjusted to 8wt% calcium bicarbonate solution, and all the other are identical with embodiment 1 operation steps. The final deacidification effect is substantially the same as in Example 1.

Abstract

The invention provides a deacidification protection method for a rubbing with a concave-convex structure. The method comprises the following steps: 1) activating the surface of the rubbing by using plasma airflow, and removing an inert layer on the surface of the rubbing, wherein plasma airflow activation is to take out plasmas generated by gas plasma discharge in a reaction chamber through air to generate plasma airflow which is used for activating the rubbing; and 2) atomizing a deacidifying agent, infiltrating the rubbing with the atomized deacidifying agent, and carrying out deacidifying treatment. According to the method, deacidification of the rubbing is completed on the premise that the concave-convex structure of the surface of the rubbing and dye and ink marks on the surface of the rubbing are not damaged.

Description

technical field [0001] The application relates to the field of deacidification protection of cultural relics, in particular to a method for deacidification protection of rubbings with concave-convex structure. Background technique [0002] Rubbing refers to a piece of paper that rubs the shape of the surface of inscriptions, stone carvings, oracle bone bronzes, coin portraits, etc., as well as the characters and patterns on them, and sticks the paper on the hard surface of the utensils. The words and patterns on the surface of the utensils are clearly reproduced on the paper. Rubbings are one of the important carriers to record the long history and culture of the Chinese nation. It is an ancient traditional skill in our country. Many lost and damaged inscriptions, bronzes and other cultural relics can be preserved because of the existence of rubbings. The paper used for rubbings is mostly rice paper with high water absorption. In ancient times, ink was mostly used as the dy...
