Description

Technical Field

[0001] This utility model relates to the field of cultural relic restoration technology, specifically to a steam softening device for damaged areas of oil-based paper murals. Background Technology

[0002] Putty application, an important technique in traditional Chinese civil engineering, dates back to the Ming and Qing dynasties. It was primarily used for moisture and corrosion protection, as well as decorative purposes, of wooden components. This technique involves creating a putty mixture of tung oil, brick ash, and blood pigments, which is then applied in layers—single coats, one layer of hemp fiber with five coats of putty, or two layers of hemp fiber with six coats of putty—to the surface of the wooden component, forming a composite layer that combines protection and artistry. The official paper murals of the Qing dynasty developed a unique technique based on this method. Their ground layer employed the putty application technique, with paper pasted on the surface before mineral pigments were applied, making them important cultural relics reflecting the art of the Qing dynasty court.

[0003] Traditional putty base coats, once cured, possess high hardness and stability, a characteristic once considered an advantage in the conservation of architectural paintings. For the restoration of painted artifacts, the industry has long followed the principle of "cleaning and scraping away the damaged areas," meaning thoroughly removing the affected parts before re-creating the base coat and then painting. This method is widely used in the restoration of ancient buildings. However, paper murals, as multi-layered composite artifacts, are prone to complex problems such as interlayer peeling, blistering, and embrittlement due to long-term environmental changes in temperature and humidity, biological erosion, etc. Because the hardened putty base coat is difficult to soften again, and the paper used for mounting shows significant fiber aging over time, the traditional "cleaning and scraping away the damaged areas" method would lead to the irreversible loss of original historical information, making it difficult to maintain the authenticity of the artifact after restoration.

[0004] For thick-layered paper murals with one layer of hemp and five layers of putty, or two layers of hemp and six layers of putty, the average thickness can reach several millimeters, making it difficult for ordinary chemical reinforcing agents to achieve deep penetration and effective softening. Although high-temperature steam can soften the putty through the thermoplastic effect of tung oil components, it faces multiple technical challenges in practice: insufficient steam pressure prevents penetration of the dense putty layer, while excessive pressure may exacerbate damage to the fragile paper layer; insufficient heat treatment time leads to incomplete softening, while excessive time accelerates adhesive aging. In addition, the defects in the various structural layers of paper murals are often interconnected. Localized warping areas may simultaneously exhibit composite damage such as putty layer cracking, hemp fiber breakage, and paper blistering. Accurate identification of the material characteristics, defect mechanisms, and mechanical states of different layers is necessary to develop an appropriate steam softening method.

[0005] In view of this, this utility model is proposed. Utility Model Content

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below. Where specific conditions are not specified in the embodiments, conventional conditions or conditions recommended by the manufacturer shall apply. Reagents or instruments whose manufacturers are not specified are all conventional products that can be purchased commercially.

[0029] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0030] Example Please refer to Figure 1 This embodiment provides a steam softening device 100 for defects in putty-coated paper murals, including a steam engine 110, a steam spray gun 120, a sealing adapter 130, and an end air outlet.

[0031] The steam engine 110 includes an operation and display unit, a steam generating unit, and a water storage tank. The steam generating unit is located inside the water storage tank and is used to convert the water in the water storage tank into steam. For example, high-temperature steam can be obtained by heating and vaporizing.

[0032] In this embodiment, the operation and display unit is located on the panel above the water storage tank. The operation and display unit includes a power switch 111, a pressure regulator 112, a temperature regulator 113, a pressure safety valve 114, a display screen 115, and an anti-dry burning indicator 116.

[0033] Among them, the power switch 111 is the main switch for controlling the operation of the steam engine 110.

[0034] The pressure regulating element 112 is used to adjust the pressure inside the steam engine 110, thereby controlling the pressure of the outflowing steam.

[0035] Temperature regulator 113 is used to adjust the water temperature inside the water storage tank in order to control the steam generation rate.

[0036] The pressure safety valve 114 is used to ensure the pressure safety of the steam engine 110 during operation. When the pressure inside the steam engine 110 rises and exceeds the safe value, the pressure safety valve 114 automatically releases pressure to prevent the steam engine 110 from being damaged due to excessive pressure.

[0037] The display screen 115 is used to display the machine's operating status and various parameters, such as the water storage capacity, water temperature, gas pressure, and voltage of the steam engine 110.

[0038] The anti-dry-burn indicator 116 is used to ensure the safe use of the steam engine 110. When the water output of the steam engine 110 is lower than the safety threshold, the indicator light of the anti-dry-burn indicator 116 will light up to remind the user and automatically cut off the power to prevent dry burning.

[0039] In other embodiments, depending on actual needs, the pressure safety valve 114, the display screen 115 and the anti-dry burning indicator 116 may be only one of them or any combination of two, but it is preferred to be a combination of the three in this embodiment to ensure the safe and convenient use of the steam engine 110.

[0040] The water storage tank is provided with a steam outlet 117 and a water inlet 118. In this embodiment, both the steam outlet 117 and the water inlet 118 are located on the panel. In other embodiments, the steam outlet 117 and the water inlet 118 may also be located on the side wall of the water storage tank, as long as the functions of water intake and steam exhaust can be realized.

[0041] The steam gun 120 is connected to the steam outlet 117 via a connecting hose 150, which facilitates the operation and adjustment of the position of the steam gun 120.

[0042] In this embodiment, the steam spray gun 120 is a handheld steam outlet control spray gun, which allows the steam flow rate to be adjusted by the gripping force. When the gripping force increases, the steam flow rate increases; when the gripping force decreases, the steam flow rate decreases.

[0043] The end-point vent is connected to the steam gun 120 via a sealing adapter 130. The sealing adapter 130 is compatible with various end-point vents and has a built-in high-temperature resistant sealing ring to effectively prevent steam leakage.

[0044] Please refer to the following: Figure 2 The end-venting component includes a silicone softening cover 141 and a steam nozzle, which includes two types: a multi-directional steam nozzle 142 and a unidirectional steam nozzle 143. It should be noted that in this embodiment, since there is only one sealing adapter 130, only one end-venting component is connected to the sealing adapter 130 at a time. Furthermore, depending on the structure of the paper mural being fumigated each time, the end-venting component is selected from any one of the following: the silicone softening cover 141, the multi-directional steam nozzle 142, or the unidirectional steam nozzle 143.

[0045] The silicone softening cover 141 can specifically repair hardened and peeling putty layers.

[0046] In this embodiment, the silicone softening cover 141 is flared, and its inner diameter gradually increases from the steam inlet end to the steam outlet 117 end.

[0047] Please refer to the following: Figure 3 In this embodiment, the steam outlet 117 end of the silicone softening cover 141 is round or square. The appropriate shape of the silicone softening cover 141 can be selected according to the condition of the disease in different parts. The remaining unused silicone softening covers 141 are reserved.

[0048] In this embodiment, the silicone softening cover 141 has three different sizes of steam outlet 117 end caps, namely 28cm and 28cm. 2 78cm 2 and 314cm 2 These correspond to small, medium, and large sizes, respectively.

[0049] It should be noted that the silicone softening cover 141 in this embodiment has large, medium and small sizes for both the circular and square steam outlets 117. Therefore, this embodiment has a total of six silicone softening covers 141 of different sizes and shapes to meet the repair needs of different areas of paper murals with different degrees of damage.

[0050] Please refer to the following: Figure 2 and Figure 4 The multi-directional steam nozzle 142 can specifically repair the relatively hard and warped burlap ground layer. By venting steam from multiple directions through the multi-directional steam nozzle 142, the burlap ground layer can be evenly moistened by steam, which is conducive to the softening and repair of the burlap ground layer, while avoiding local over-softening or over-hardening that could damage the paper mural.

[0051] In this embodiment, the multi-directional steam nozzle 142 has a plurality of first steam outlets 1421; the plurality of first steam outlets 1421 are equidistantly spaced along the axial direction of the multi-directional steam nozzle 142, the distance between two adjacent first steam outlets 1421 is 1cm, and the directions of two adjacent first steam outlets 1421 differ by 90°, so that the side view projection of the plurality of first steam outlets 1421 forms a regular quadrilateral.

[0052] Please refer to the following: Figure 4 The one-way steam nozzle 143 is used for targeted repair of relatively hard and warped burlap ground layers, especially the deeper areas within the burlap ground layer. If the warped joint of the burlap ground layer is far from the edge of the warp, it cannot be effectively and evenly moistened. By using the one-way steam nozzle 143 to specifically spray steam to soften the warp, the paper mural restoration can be carried out smoothly.

[0053] Therefore, in this embodiment, the one-way steam nozzle 143 has a second steam outlet 1431, which is located at the end of the one-way steam nozzle 143 away from the sealing adapter 130.

[0054] The steam nozzle provided in this embodiment has three lengths: 25cm, 45cm, and 65cm, corresponding to small, medium, and large sizes, respectively.

[0055] Since the multi-directional steam nozzle 142 and the unidirectional steam nozzle 143 provided in this embodiment both have the above three sizes, the steam nozzles provided in this embodiment have a total of 6 different models or sizes, so that the appropriate steam nozzle can be selected according to the condition of the damaged area of ​​the paper mural.

[0056] In this embodiment, the outer diameter of the steam nozzle is 1.6 mm. Due to its small outer diameter, it can penetrate deep into the interior of the paper mural damage without affecting the paper mural restoration process.

[0057] In addition, the steam nozzles in this embodiment are all hollow tubes to facilitate steam transport. The inner diameter of the steam nozzle is 1.2 mm, the orifice diameter of the first steam outlet 1421 is 1 mm, and the orifice diameter of the second steam outlet 1431 is 1 mm.

[0058] In this embodiment, a universal joint 160 is provided between the steam nozzle and the sealing adapter 130. The universal joint 160 can be a flexible hose to ensure that the steam nozzle can penetrate deep into the damaged area of ​​the paper mural.

[0059] The steam softening device 100 provided in this embodiment for treating defects in putty-covered paper murals has at least the following advantages: The silicone softening hood 141 effectively seals steam within the repair area, maintaining a high-humidity state in the cracked, warped, and deformed surface layer for a certain period. The steam does not dissipate immediately after entering the hood, thus improving fumigation efficiency. This avoids the drawbacks of traditional steam fumigation processes, which only offer point-to-point fumigation, resulting in low efficiency, slow speed, long fumigation time for the artifact, and a large affected area.

[0060] The multi-directional steam nozzle 142 and the unidirectional steam nozzle 143 are mainly designed for fumigation of the back of hollow burlap ground layer. Compared with the old-fashioned steam engine 110 nozzle, which is shorter and has only one air outlet, making it unable to effectively soften deeper hollow burlap layers, the multi-directional steam nozzle 142 and the unidirectional steam nozzle 143 can effectively perform targeted fumigation and softening of the affected area, greatly improving fumigation efficiency and enhancing the softening and repair effect.

[0061] The structural design of the temperature regulating component 113, the pressure regulating component 112, and the handheld steam exhaust control spray gun greatly improves the controllability of the softening fumigation step, and significantly enhances the safety and operability of the cultural relic during the restoration process.

[0062] The pressure relief valve 114 and the anti-dry-burn indicator 116 effectively ensure the safety of cultural relics during the restoration process.

[0063] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
