Description

Technical Field

[0001] The invention relates to the technical field of cultural relics reinforcement, and in particular to a reinforcement method and a reinforcement device for rapid reinforcement of bone and horn cultural relics, and is particularly suitable for reinforcement of bone and horn cultural relics at archaeological sites. Background Art

[0002] Bone and keratin artifacts can be mineralized to form fossils in a long-term underground burial environment, and their properties are relatively stable. However, a large number of bone artifacts encountered in archaeological excavations have not yet been fully mineralized due to their relatively short burial time. They are affected by many factors such as their own composition and properties, surrounding soil, changes in environmental temperature and humidity, water effects, microenvironment acidity and alkalinity, soil soluble salts, native mold, and the effects of animals and plants. They have suffered from many diseases and are seriously decayed. Their interiors are very fragile and urgently need protection and reinforcement.

[0003] In some existing technologies, calcium hydroxide can be added to bone and keratin artifacts for protection. However, calcium hydroxide-based materials have low initial strength and need to react with carbon dioxide in the air to generate calcium carbonate to provide strength. The carbon dioxide content in the air is only 0.03%, and after the surface of calcium hydroxide is carbonized to generate calcium carbonate, it will further hinder the carbonization process, often requiring a long carbonization time, resulting in a slow increase in the strength of calcium hydroxide-based materials.

[0004] In addition, bone and keratin artifacts unearthed in humid environments often have a high moisture content, and if not treated at room temperature, the moisture will quickly lose. The moisture stored inside may play a certain bonding role, and if it loses water, it is likely to cause it to further lose its bonding strength, resulting in cracking, disintegration, powdering and other diseases.

[0005] Therefore, the prior art needs to be further improved. Summary of the invention

[0006] The invention provides a reinforcement method and a reinforcement device for quickly reinforcing bone and horny cultural relics, so as to solve the technical problem that the existing bone and horny cultural relics have a slow solidification speed.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work belong to the scope of protection of the present invention. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In the present invention, unless otherwise specified, the directional words used, such as "up", "down", "left", "right", "front", and "back", generally refer to the up, down, left, and right of the device in actual use or working state, specifically the drawing direction in the accompanying drawings.

[0021] It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments of the present invention. In addition, in the following embodiments, the description of each embodiment has its own emphasis, and for parts not described in detail in one embodiment, reference can be made to the relevant description of other embodiments.

[0023] Take the water-saturated ivory unearthed as an example, its bone structure has been destroyed and the organic adhesive material has almost disappeared. Due to the lack of appropriate protection technology at the time, these rotten ancient ivory unearthed from the underground water-saturated environment quickly lost water after being unearthed, and began to crack, disintegrate, and powderize, thus losing its cultural value.

[0024] At present, bone cultural relics are mainly reinforced by chemical materials. Among them, calcium hydroxide has the advantages of good compatibility with the reinforced objects, good durability, environmental friendliness, and no breeding of microorganisms. It is often used for the reinforcement of stone cultural relics. It can also be used for the reinforcement of bone and keratin cultural relics, earthen sites, mural restoration, paper deacidification and other fields.

[0025] However, when calcium hydroxide is used to reinforce newly unearthed bone cultural relics, due to its long carbonization time and the need to ensure the moisture content of the bone cultural relics, the existing curing scheme needs to be further improved to accelerate the curing speed of the bone cultural relics while ensuring the moisture content of the surface of the bone cultural relics.

[0026] Based on this, the present invention provides a reinforcement method and a reinforcement device for rapid reinforcement of bone and horny cultural relics.

[0027] See also Figure 1-5 On the one hand, the present invention provides a reinforcement method for rapid reinforcement of bone and horny cultural relics, the method comprising the following steps: S100: Introducing nano calcium hydroxide suspension onto the surface of the unearthed water-saturated bone and keratin cultural relics, and placing the bone and keratin cultural relics in a closed environment.

[0028] There are many ways to introduce the nano sodium hydroxide suspension into the bone horn cultural relics, and the present invention is not limited thereto. In a specific embodiment, the suspension can be added dropwise onto the bone horn cultural relics. The advantage of using the drip method is that when the bone horn cultural relics are irregular in shape, the suspension can be better introduced into the corners of the bone horn cultural relics.

[0029] In another alternative specific embodiment, the nano calcium hydroxide suspension can also be introduced by spraying. The advantage of spraying is that when the bone keratin artifacts are of regular shape, uniform spraying can be achieved better.

[0030] It should be understood that the reason for selecting nano sodium hydroxide suspension is that it can allow calcium hydroxide to penetrate into the bone keratin cultural relics as much as possible, optimize the reinforcement effect, and improve the reinforcement strength of the bone keratin cultural relics.

[0031] S200: preparing a supersaturated salt solution, and placing the supersaturated salt solution in a closed environment.

[0032] At room temperature, add water into a beaker, add salt according to its solubility and stir continuously until solids remain in the beaker to obtain a saturated salt solution. Then add excess salt to prepare a supersaturated salt solution.

[0033] As mentioned earlier, bone and keratin artifacts unearthed in humid environments often have a higher moisture content. For example, the moisture content of unearthed rotten ivory is about 45%. If it is not treated at room temperature, the moisture will be lost quickly.

[0034] Based on this, the present invention adopts the method of saturated aqueous solution of soluble salt. After the soluble salt is dissolved in water, it will be ionized to produce positively charged metal ions and negatively charged ions. Water is a polar solvent, and the ionized charged ions will attract polar water molecules, which will hinder the evaporation of water and reduce the number of water molecules evaporated per unit time. If the salt solution is in a closed container and the temperature is constant, the evaporation of the solution and the condensation of gas phase water molecules will eventually establish a balance, and the vapor pressure of the solution will remain constant, that is, a fixed humidity is generated.

[0035] The saturated salt solution is extremely simple to control humidity, but it is very practical, and the humidity of various salts is very stable and has excellent repeatability. Therefore, the present invention adopts the saturated salt solution standard given by the OIML international recommendation to select a saturated salt solution, and then control the humidity. Furthermore, the use of supersaturated salt solution to control humidity does not require additional power supply, which is more suitable for archaeological sites with complex situations, and realizes the first-time protection of bone and keratin cultural relics.

[0036] In addition, more importantly, in the process of reinforcing bone and keratin artifacts, the use of a saturated aqueous solution of soluble salts is not only to provide a higher humidity to slow down the loss of water in bone and keratin artifacts, but another more important purpose is that by using a salt solution to provide a higher humidity, the carbonization rate of calcium hydroxide can also be accelerated.

[0037] S300: introducing carbon dioxide into the closed environment.

[0038] When adding carbon dioxide to a closed environment, it is preferred to place dry ice or connect a carbon dioxide cylinder. The advantage of doing so is that it does not require electricity and is more suitable for the complex environment of the archaeological site, thus achieving the first-time protection of bone and keratin artifacts.

[0039] S400: Detecting calcium hydroxide introduced into the bone keratin cultural relic using a Raman spectrometer. When calcium hydroxide is not detected but calcium carbonate is detected, the reinforcement of the bone keratin cultural relic is completed.

[0040] In the prior art, since the reinforcement time of bone and keratin artifacts is relatively long, the reinforcement may take more than a week or even longer. Therefore, archaeologists mostly choose redundant reinforcement when carrying out reinforcement, that is, they choose to take out the bone and keratin artifacts after seven days or longer, at which time the reinforcement of the bone and keratin artifacts is considered to be completed.

[0041] However, the problem is that it is uncertain whether the bone-horn cultural relics have been completely reinforced, and at the same time, it is not conducive to the rapid reinforcement of bone-horn cultural relics. In the present invention, by using a Raman spectrometer to detect the changes in calcium hydroxide introduced into the bone-horn cultural relics during the reinforcement process, the reinforcement of the bone-horn cultural relics can be better understood. When the Raman spectrometer does not detect calcium hydroxide, but detects calcium carbonate, it can be considered that the calcium hydroxide introduced into the bone-horn cultural relics has basically completed carbonization.

[0042] Therefore, through this solution, the solidification of unearthed water-saturated cultural relics can be well achieved while ensuring the moisture content of bone and keratin cultural relics.

[0043] Furthermore, after step S300 and before step S400, the following steps are also included: S310: Using a Raman spectrometer to identify areas with high calcium hydroxide content on the surface of bone-keratin artifacts, spraying carbon dioxide on the areas with high calcium hydroxide content on the surface of the bone-keratin artifacts, so that carbon dioxide is difficult to enter the most vulnerable cracks of the bone-keratin artifacts, accelerating carbonization of calcium hydroxide, and allowing the bone-keratin artifacts to obtain initial strength as soon as possible.

[0044] In the operation steps of the present invention, by using a Raman spectrometer and a spraying device, better reinforcement and solidification of bone and keratin cultural relics can be achieved. In the prior art, the concentration of carbon dioxide in the overall environment is consistent, while the introduced calcium hydroxide is not evenly distributed in the bone and keratin cultural relics, and the areas with more calcium hydroxide are more difficult to carbonize. At the same time, carbon dioxide is more difficult to enter the most vulnerable cracks of bone and keratin cultural relics than other areas, and calcium hydroxide in these areas is often more difficult to carbonize.

[0045] At the same time, more importantly, since the water content of the newly unearthed bone and keratin artifacts is relatively high, and the water molecules inside the artifacts play a certain bonding role, in this case, as the artifacts continue to lose water, the bonding strength inside the artifacts decreases. If the introduced calcium hydroxide cannot be carbonized as soon as possible to play a reinforcing role, the bone and keratin artifacts may break due to water loss.

[0046] In the reinforcement of bone and keratin cultural relics, there is a certain corresponding relationship between the cracks and the calcium hydroxide content. The introduced calcium hydroxide will be preferentially distributed in the cracks. When the cracks are filled with calcium hydroxide, the calcium hydroxide content in the cracks is higher than that in non-cracks.

[0047] The Raman spectrometer's incident light interacts with the chemical bonds in the sample to produce Raman scattering, which can easily determine the calcium hydroxide content at different locations. When measuring the calcium hydroxide content in different areas of the cultural relic surface one by one, ensure that the Raman spectrometer is at the same height from the area. By comparison, the area with high calcium hydroxide content on the surface of bone keratin cultural relics can be determined.

[0048] At the same time, based on the identification results of the Raman spectrometer, when carbon dioxide is introduced, the spray device is set in the areas with higher calcium hydroxide on the bone keratin artifacts. These areas contain some cracks that are difficult for carbon dioxide to enter. Spraying carbon dioxide in these areas through the spray device can further accelerate the carbonization speed of calcium hydroxide in the area, and at the same time, make the fragile crack area gain strength as soon as possible.

[0049] Furthermore, after S400, the method further includes S500: sampling the bone keratin cultural relics, grinding them, and determining the carbonization status of calcium hydroxide using XRD.

[0050] By using XRD to observe the calcification of bone and keratin cultural relics, the carbonization status of bone and keratin cultural relics can be detected relatively well, and further restoration can be carried out based on the carbonization status. For example, when insufficient carbonization is detected, a secondary reinforcement can be carried out to ensure that the reinforcement is completed in the shortest possible time after the cultural relics are unearthed, avoiding later damage to the cultural relics due to incomplete reinforcement.

[0051] Furthermore, in order to better achieve the reinforcement of bone and keratin cultural relics, the ambient temperature of the closed environment during the reinforcement process of bone and keratin cultural relics is preferably 20 degrees Celsius, which can slow down the water loss of bone and keratin cultural relics.

[0052] The second aspect of the present invention also provides a reinforcement device for bone and keratin cultural relics, the device comprising a housing, a Raman spectrometer, a spraying device, an introduction device and a controller, the controller being connected to the Raman spectrometer, the spraying device, the introduction device being used to introduce a drop of calcium hydroxide suspension onto the surface of the bone and keratin cultural relics; the spraying device being used to introduce carbon dioxide into the closed cavity, and selectively spraying carbon dioxide in areas with high calcium hydroxide content in the bone and keratin cultural relics.

[0053] The box is provided with a closed cavity to accommodate bone and keratin artifacts and a spraying device, and a humidity container is provided in the closed cavity to hold a supersaturated salt solution; the Raman spectrometer is used to identify calcium hydroxide and areas with high calcium hydroxide content in bone and keratin artifacts; the spraying device includes a spraying unit and a concentration control unit, the spraying unit is connected to the concentration control unit, and the spraying unit is connected to the Raman spectrometer, the spraying unit is used to spray carbon dioxide in the area with high calcium hydroxide content based on the identification result of the Raman spectrometer, and the concentration control unit is used to control the concentration of carbon dioxide in the entire closed cavity; the introduction device is connected to the closed cavity to introduce nano calcium hydroxide solution into the bone and keratin artifacts.

[0054] When the bone and horn artifacts need to be reinforced, the bone and horn artifacts are placed in a closed cavity to start the subsequent reinforcement process.

[0055] Then, the controller first controls the introduction device to introduce the nano calcium hydroxide suspension into the entire surface of the bone keratin cultural relic, and then controls the concentration control unit of the spraying device to introduce carbon dioxide into the closed cavity.

[0056] Then the controller performs a curing acceleration treatment on the bone and keratin cultural relics, controls the Raman spectrometer to detect the calcium hydroxide content of the bone and keratin cultural relics, and sprays carbon dioxide to the area with high calcium hydroxide content through the spraying unit of the spraying device.

[0057] Finally, the controller determines whether the bone and keratin cultural relics have been reinforced based on the Raman spectrometer. When the cultural relics are detected by the Raman spectrometer, when no calcium hydroxide is detected, it can be considered that the calcium hydroxide has been completely converted into calcium carbonate, that is, the reinforcement of the bone and keratin cultural relics is basically completed.

[0058] Furthermore, the spraying device includes a carbon dioxide storage unit, which is a dry ice storage tank or a carbon dioxide cylinder, so that the reinforcement device for bone and horny artifacts can be well applied in the field of on-site archaeology.

[0059] Furthermore, the reinforcement device for bone and keratin cultural relics also includes a humidity control unit, which is used to control the humidity in the closed cavity to 80%-90% RH.

[0060] The purpose of controlling the humidity of the sealed cavity in the reinforcement device of bone and keratin cultural relics is that when the humidity in the sealed cavity is too high, it will not accelerate the carbonization rate of the bone and keratin, but will slow down its carbonization rate.

[0061] It should be understood that there are many humidity control methods in the prior art, which are not impossible to implement, and the present invention is not limited thereto. The present invention is exemplified below.

[0062] In a specific embodiment, the humidity control unit includes a humidity detector, a humidity container, a baffle and a humidity controller. The humidity controller is connected to the humidity detector and the baffle. The baffle is arranged on the humidity container for selectively switching the humidity container. The humidity container is a beaker containing a saturated salt solution. The humidity detector is used to detect the humidity in the closed cavity of the reinforcement device of the bone and keratin cultural relics.

[0063] When the humidity controller detects through the humidity detection agent that the humidity in the closed cavity does not meet the preferred range, the control baffle is removed to allow the humidity container to increase the humidity in the closed cavity until the humidity in the closed cavity is within the preferred range. The humidity controller controls the baffle to be completely introduced onto the humidity container to prevent the humidity container from increasing the humidity into the closed cavity.

[0064] Furthermore, the concentration control unit of the spraying device is used to control the concentration of carbon dioxide in the closed cavity.

[0065] The purpose of controlling the concentration of carbon dioxide is that during the solidification process of bone and keratin artifacts, when the concentration of carbon dioxide is too high, it will further slow down the carbonization rate of calcium hydroxide and achieve the opposite effect.

[0066] It should be understood that there are many concentration control units in the prior art, which are not impossible to implement, and the present invention is not limited thereto. The present invention is exemplified below.

[0067] In a specific embodiment, the concentration control unit includes a concentration detection agent, a concentration container, a valve and a concentration controller. The concentration controller is connected to the concentration detection agent and the valve. The valve is arranged on the concentration container for selectively switching the concentration container. The concentration container is a carbon dioxide cylinder. The concentration detection agent is used to detect the concentration in the closed cavity of the reinforcement device of the bone and keratin cultural relics.

[0068] When the concentration controller detects through the concentration detector that the concentration in the closed cavity does not meet the preferred range, it controls the baffle to be removed, so that the concentration container can increase the concentration in the closed cavity until the concentration in the closed cavity is within the preferred range. The concentration controller then controls the valve to completely close the concentration container, preventing the concentration container from increasing the concentration in the closed cavity.

[0069] See also Figure 3 The third aspect of the present invention further provides a reinforcement method based on the reinforcement device, the method comprising: S1000: Check whether the bone and horny cultural relics are placed in a closed cavity; S2000: reinforcing the bone-horn cultural relic, including introducing a nano sodium hydroxide suspension into the bone-horn cultural relic and introducing carbon dioxide into the closed cavity; S3000: accelerating the curing of the bone keratin cultural relic, wherein the curing acceleration includes identifying areas with high calcium hydroxide content in the bone keratin cultural relic and spraying carbon dioxide on the areas with high calcium hydroxide content; S4000: Determine whether the bone keratin cultural relic has been reinforced based on the Raman spectrometer.

[0070] The present invention is further described below with specific implementation examples and experimental examples. It should be understood that these implementation examples are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0071] Example See also Figure 4 This embodiment provides a reinforcement device suitable for an archaeological site, comprising: a box 1, a humidity control unit 5, a concentration control unit 8 for controlling the concentration of carbon dioxide, a placement platform 7 for accommodating bone and keratin artifacts, an introduction device for dripping nano-calcium hydroxide suspension (not shown in the figure) and a Raman spectrometer 15.

[0072] The box body 1 is a hollow sealed cavity, which is enclosed by a cover plate 2. The multiple cover plates 2 are sealed and connected by a sealing rubber, and the front cover plate and the bottom cover plate are connected by a spring lock 4 to realize the opening or closing of the sealed cavity of the box body 1. The cover plate 2 is a transparent acrylic plate, or a glass plate and a metal plate.

[0073] The humidity control unit 5 and the concentration control unit 8 are placed below the placement platform in the closed cavity of the box 1. The humidity control unit 5 includes a beaker containing a saturated salt solution and the saturated salt solution. The concentration control unit 8 includes a dry ice placement tank containing dry ice and dry ice.

[0074] A spraying unit 14 and an introduction device (not shown in the figure) of a spraying device are placed above the closed cavity of the box body 1. The spraying unit 14 is connected to the box body through a guide rail 12 and a slider 13. The guide rail 12 includes a first parallel track arranged in the front-to-back direction, and a second track connected to the first track. The slider 13 is arranged on the second track, and the slider 13 can move left and right relative to the second track. Therefore, since the second track can move forward and backward relative to the first track, and the slider can move left and right relative to the second track, the spraying of carbon dioxide on a specific area of ​​a specific surface of a bone keratin cultural relic can be achieved.

[0075] The slider 13 is connected to the Raman spectrometer 15 and the introduction device 3. When it is necessary to drip the nano calcium hydroxide suspension on the other parts of the bone keratin artifact and detect it with the Raman spectrometer, the operator manually turns the bone keratin artifact over so that all surfaces of the bone keratin artifact are detected by the Raman spectrometer 15, so that the spray unit 14 of the spray device sprays carbon dioxide in the area with high calcium hydroxide content based on the detection result of the Raman spectrometer.

[0076] The advantage of this arrangement is that, although slightly cumbersome, it is particularly suitable for archaeological sites. As mentioned earlier, due to the complex conditions at the archaeological site, there may be a problem of insufficient power supply, and the reinforcement device needs to be moved back and forth. Through this solution, the structural complexity of the reinforcement device can be reduced as much as possible, making it easier for archaeologists to assemble it on site and carry it, while also being able to complete the reinforcement of bone and keratin artifacts.

[0077] It should be noted that, in a specific embodiment of the present invention, the introduction device does not exist, but is manually operated by archaeologists. The main reason is that the unearthed bone and keratin cultural relics have different shapes and damages due to the large differences in the burial environment. The use of an introduction device with a specific structure is difficult to meet the needs of all types of bone and keratin cultural relics, which causes many inconveniences at the archaeological site.

[0078] Furthermore, the placement platform 7 is provided with two layers, and can be selectively placed on the first layer or the second layer according to the size of the bone keratin artifacts. When placed on the second layer below the first layer, the placement platform of the first layer needs to be removed to facilitate the spraying device 14 and the Raman spectrometer 15 to perform dripping and detection.

[0079] Experimental Example 1 This example is a control experiment, in which the bone keratin cultural relic samples are placed indoors and naturally carbonized in the air at a humidity of about 60% RH, without using carbon dioxide to accelerate the carbonization.

[0080] On the third day, the sample of this embodiment was sampled, ground into powder using a mortar, and then measured using an X-ray powder diffractometer (XRD) to obtain a diffraction pattern as shown below: Figure 5 As shown, Figure 5 This indicates that only a portion of the calcium hydroxide sample has turned into calcium carbonate. Quantitative analysis using the RIR method shows that calcium hydroxide accounts for about 74% of the sample, and the vast majority of the calcium hydroxide has not yet been carbonized.

[0081] Experimental Example 2 Select a supersaturated potassium chloride solution to provide appropriate humidity. At room temperature, add water to a beaker, then add potassium chloride thereto and stir continuously until potassium chloride solids remain in the beaker and can no longer be dissolved, to obtain a saturated potassium chloride solution, then add potassium chloride to prepare a supersaturated potassium chloride solution. The solution is placed in the humidity control unit in the accelerated carbonization box of the present invention, and the humidity in the environmental box can be maintained at 85-86%RH as measured by the humidity sensor.

[0082] The samples are placed on a placement platform in the accelerated carbonization box of the present invention, and a carbonization acceleration experiment is carried out in a closed environment.

[0083] On the third day, the sample of this embodiment was sampled, ground into powder using a mortar, and then measured using XRD to obtain its diffraction pattern as shown below: Figure 5 As shown, Figure 5 This indicates that only a portion of the calcium hydroxide sample has turned into calcium carbonate. Quantitative analysis using the RIR method shows that calcium hydroxide accounts for about 68% of the sample, and the vast majority of the calcium hydroxide has not yet been carbonized.

[0084] Experimental Example 3 This embodiment is substantially the same as embodiment 2, except that a supersaturated potassium sulfate solution is selected to provide appropriate humidity. At room temperature, water is added to a beaker, and then potassium sulfate is added thereto and stirred continuously until potassium sulfate solid remains in the beaker and can no longer be dissolved, thereby obtaining a saturated potassium sulfate solution, and potassium sulfate is then added to prepare a supersaturated potassium sulfate solution. The solution is placed in a humidity control unit in the accelerated carbonization box of the present invention, and the humidity in the environmental box can be maintained at 92-93%RH as measured by a humidity sensor.

[0085] The samples are placed on a placement platform in the accelerated carbonization box of the present invention, and a carbonization acceleration experiment is carried out in a closed environment.

[0086] On the third day, the above samples were sampled, ground into powder using a mortar, and then the diffraction pattern was measured using XRD. Figure 5 As shown, Figure 5 This indicates that only a portion of the calcium hydroxide sample has turned into calcium carbonate. Quantitative analysis using the RIR method shows that calcium hydroxide accounts for about 63% of the sample, and the vast majority of the calcium hydroxide has not yet been carbonized.

[0087] Experimental Example 4 In this embodiment, a saturated salt solution is not placed in the humidity control unit in the accelerated carbonization box. The humidity in the environmental box can be maintained at 60-65%RH as measured by the humidity sensor.

[0088] Dry ice was used to provide a carbon dioxide atmosphere, and a carbon dioxide concentration meter was used to measure the CO2 concentration and monitor the CO2 concentration changes. After 10 g of dry ice was put in, the CO2 concentration in the box was higher than the maximum limit of 9999 ppm of the carbon dioxide concentration meter.

[0089] The samples are placed on a placement platform in the accelerated carbonization box of the present invention, and a carbonization acceleration experiment is carried out in a closed environment.

[0090] On the third day, the CO2 concentration was measured using a carbon dioxide concentration meter, and the CO2 concentration in the box was still higher than 9999 ppm. The above samples were sampled, ground into powder using a mortar, and then the diffraction pattern was measured using XRD as shown below: Figure 5 As shown, Figure 5 This indicates that most of the calcium hydroxide samples have turned into calcium carbonate. Quantitative analysis using the RIR method shows that calcium carbonate accounts for about 95% of the samples, and most of the calcium hydroxide has been carbonized.

[0091] Experimental Example 5 This embodiment is basically the same as embodiment 2, except that a supersaturated potassium chloride solution is selected to provide appropriate humidity, and the difference is that dry ice is selected to provide a carbon dioxide atmosphere, and a carbon dioxide concentration meter is used to measure the CO2 concentration and monitor the change of CO2 concentration. After 10 g of dry ice is placed, the CO2 concentration in the box is higher than the maximum limit of 9999 ppm of the carbon dioxide concentration meter.

[0092] The samples are placed on a placement platform in the accelerated carbonization box of the present invention, and a carbonization acceleration experiment is carried out in a closed environment.

[0093] On the third day, the CO2 concentration was measured using a carbon dioxide concentration meter, and the CO2 concentration in the box was still higher than 9999 ppm. The above samples were sampled, ground into powder using a mortar, and then the diffraction pattern was measured using XRD as shown below: Figure 5 As shown, no calcium hydroxide was found in the X-ray diffraction pattern, indicating that the calcium hydroxide sample has all been converted into calcium carbonate.

[0094] Experimental Example 6 This embodiment is basically the same as the embodiment 3, except that a supersaturated potassium sulfate solution is selected to provide appropriate humidity, and the difference is that dry ice is selected to provide a carbon dioxide atmosphere, and a carbon dioxide concentration meter is used to measure the CO2 concentration and monitor the change of CO2 concentration. After 10 g of dry ice is placed, the CO2 concentration in the box is higher than the maximum limit of 9999 ppm of the carbon dioxide concentration meter.

[0095] The samples are placed on a placement platform in the accelerated carbonization box of the present invention, and a carbonization acceleration experiment is carried out in a closed environment.

[0096] On the third day, the CO2 concentration was measured using a carbon dioxide concentration meter, and the CO2 concentration in the box was still higher than 9999 ppm. The above samples were sampled, ground into powder using a mortar, and then the diffraction pattern was measured using XRD as shown below: Figure 5 As shown, no calcium hydroxide was found in the X-ray diffraction pattern, indicating that the calcium hydroxide sample has all been converted into calcium carbonate.

[0097] It can be seen from the above examples and comparative examples that under high humidity and high carbon dioxide concentration, the carbonization speed of calcium hydroxide is greatly increased, and more calcium carbonate is obtained by carbonization in the same time. The present invention can accelerate the carbonization of calcium hydroxide.
