Example Embodiment

[0019] Example 1

[0020] Prepare the simulated gypsum crust sample: first clean the fresh bluestone sample (size 100mm×50mm×10mm) with distilled water, and then dry it in an oven at 105℃ for 24h. Mix gypsum powder and deionized water 1:3 (m:m) evenly (gypsum powder solidifies fast, ready for use), refer to JC / T 973-2005 (natural stone protective agent for building decoration) on the sample surface Brush evenly three times and let it dry naturally at room temperature for 7 days.

[0021] Based on the chromaticity value of the fresh lapis lazuli, measure the chromaticity value of the sample before and after cleaning in the cleaning area. Calculate the change of color difference before and after gypsum coating, the change of color difference before and after cleaning, and the change of color difference between fresh sample after cleaning. Record photos of the cleaning process.

[0022] Prepare a 5% EDTA disodium salt solution at room temperature, use an ultrasonic vibration brush to...

[0026] Example 2

[0027] Ink stained sample: first clean the fresh lapis lazuli sample (size 100mm×50mm×10mm) with distilled water, and then dry it in an oven at 105℃ for 24h. Use a marker to write "1" on the surfaces of the two samples.

[0028] Use Anyty V500IR / UV portable digital microscope to observe the surface micro-morphology of the simulated ink stain sample before and after cleaning. Record photos of the cleaning process.

[0029] Dip a proper amount of acetone (analytical pure) solvent with an ultrasonic vibration brush, place it on the surface of the sample to be cleaned, turn on the switch, and vibrate evenly in the cleaning area for 2 minutes, gently spray the surface with a small spray can of deionized water to wash away the residual solvent on the surface , Observe the cleaning effect.

[0030] by image 3 It can be observed that after cleaning with ultrasonic vibration brush + acetone, there is almost no ink on the sample. Observed with a video microscope under 60...

Abstract

The invention discloses an ultrasonic vibration brush cleaning method for stone cultural relics, and belongs to the technical field of cleaning of the stone cultural relics. According to the ultrasonic vibration brush cleaning method, an ultrasonic vibration brush and a chemical cleaning agent are adopted, so that a physical cleaning method and a chemical cleaning method are combined. The specific cleaning operation comprises the following steps: dipping the ultrasonic vibration brush with a proper amount of the chemical cleaning agent, carrying out uniform vibrating and cleaning for several minutes on the surfaces of stone and the stone cultural relics or on the corrosion regions on the surfaces, and spraying and washing the cleaning the regions by using spray mist containing deionized water to remove the residual solvent.

Description

technical field [0001] The invention belongs to the technical field of cleaning stone cultural relics, in particular to an ultrasonic vibration brush cleaning method for stone cultural relics. [0002] technical background [0003] The Stone Age is the first era of human history and civilization. The historical process of human utilization and mining of rocks is almost in sync with the development of human beings. Because of its good weather resistance, rock materials are widely used in buildings, structures and artworks, such as stone towers, grottoes, steles, etc. These different forms of stone cultural relics have precious historical, scientific and artistic value, and are a valuable historical heritage. However, in recent years, air pollution problems such as acid rain and smog have led to the formation of gray-black gypsum crusts on the surface of cultural relics, moss, mold and other organisms parasitic on the surface of cultural relics, and man-made pollution such as ...
