Problems solved by technology

At present, the sublimation speed of these temporary solid materials is single, and they cannot provide a series of material systems with gradient removal rates; they cannot meet the requirements of cultural relic protection workers for the artificially adjustable duration of temporary solid effects; they cannot meet different excavation conditions. The actual needs of the archaeological site

Embodiment 1

[0055] Camphene Used in the Extraction of Painted Relics

[0056] Clean up the soil on the surface of the painted relics to be extracted and separate them from the surrounding relics. After heating and melting the camphene, use a brush to apply it on the surface of the painted relic. When brushing, make sure that the brush stays on the surface of the relic for 1-2 seconds to ensure that the liquid penetrates. After brushing once, spread gauze on the surface of the relic to ensure The gauze is docile on the surface of the remains, and then the molten amphene liquid is brushed on the gauze. After solidification, the painted relics were taken indoors as a whole. Permanent reinforcement from the back with acrylic emulsion AC33. Place the remains in a fume hood, let the camphene volatilize naturally at room temperature, and remove the gauze. Then reinforce it with acrylic emulsion AC33 from the front until the painted relics are thoroughly reinforced and reach a certain strength...

[0059] Camphor is used in the extraction of broken pottery

[0060] Separate the pottery from other surrounding relics, ensure that the relative position of each piece of pottery is the same as when it was unearthed, clean up the soil around the pottery, cover the whole pottery with gauze, brush the molten camphor twice, and wait for the first time to solidify Finally, brush again to ensure strength. Extract the reinforced pottery as a whole, wrap it with plastic film, put it in the storage box, and wait for the right time to carry out subsequent protection treatment.

[0061] The pottery extracted by the above method is broken into dozens of fragments, the texture is fragile, and the relative position information between the pottery pieces needs to be guaranteed. After being reinforced with camphor, the plastic film is wrapped to delay the volatilization of camphor, which can keep the extracted pottery with a certain strength within half a year and can withstand certain hand...

[0063] Use of naphthalene in the extraction of burial murals

[0064] Determine the scope of the mural to be removed, do a good job of recording such as taking pictures and measuring in the early stage, use charcoal to bake the picture, reduce the moisture content of the mural, spread the cut gauze of appropriate size on the surface of the mural, and apply the molten naphthalene brush on the gauze , stay for a few seconds to ensure that naphthalene can penetrate into the mural, and after the first pass is cured, brush again to ensure that the mural and the gauze are consolidated into one, separate the mural from the support behind it, and place the shoveled mural on a bag On the support of the sponge, carry it out of the tomb. In the laboratory, place the removed mural in a fume hood, blow the surface of the mural with a hair dryer, accelerate the volatilization of naphthalene, remove the gauze, infiltrate the permanent reinforcing agent MC76 from the back, and then perform pe...

Abstract

The invention belongs to the field of archaeological and cultural relics protection, and relates to a temporary reinforcing material and application of a material to archaeological fragile remain extraction. The temporary reinforcing material comprises any one of camphene, camphor, naphthalene and menthyl lactate or comprises any two or three or four of camphene, camphor, naphthalene and menthyl lactate; in the process of applying the temporary reinforcing material to the archaeological excavation process, the unearthed fragile remain is subject to temporary reinforcing firstly, then, extracting or uncovering is carried out, then, the remain is transported or moved to an indoor portion, then, the temporary reinforcing material is manually removed, finally, a permanent reinforcing agent isapplied. The selection range of the temporary reinforcing material is expanded, the problem that at present, the menthol material is single in removal speed is solved, meanwhile, the temporary reinforcing material has the gradient sublimation speed, the actual needs of different archaeological sites or cultural relic repair sites to the keeping time of the temporary reinforcing effect are met, andthe aim of adjusting the removal speed of the temporary reinforcing material manually is achieved.

Description

technical field [0001] The invention belongs to the field of archaeology and cultural relics protection, and in particular relates to a type of temporary solid material and its application in the extraction of archaeologically unearthed fragile remains. Background technique [0002] At archaeological excavation sites, many relics and relics that are seriously decayed and fragile, leaving only traces of damage are often unearthed, such as fragments of painted lacquerware, decayed wooden remains, and muddy and ashesed textiles. These extremely fragile remains are fragile at the touch of a touch and cannot be exposed for a long time. They need to be safely extracted as soon as they are unearthed and transferred to the restoration room for subsequent protection. When many relics were unearthed, they were mixed with various materials, and they were stacked together, such as the stacked and deformed coffin lids, which needed to be carefully peeled off before layered extraction. M...
