Description

Technical Field

[0001] This application relates to the field of desiccant technology, and more particularly to a color-changing desiccant packaging structure and server packaging. Background Technology

[0002] A server is a type of computer that runs faster, handles higher loads, and is more expensive than a regular computer. Its English name is "Server," and it refers to a dedicated computer that provides services to clients in a network environment. Server products contain a large amount of metal in their electronic components and integrated circuits. High humidity promotes corrosion and rust, leading to short circuits and damage to these components and integrated circuits. Excessive ambient humidity can severely impact products. Furthermore, the mechanical properties of packaging decrease significantly in high humidity environments. Rain, snow, dew, waves, and accidental water spills during product storage and transportation can all expose products to high humidity. Therefore, proper moisture-proofing of both the product and its packaging is crucial. One of the most common methods of moisture protection is the use of desiccants. The biggest problem with desiccants is that they become saturated with water before use or during packaging, leading to product rusting, short circuits, and other problems. Currently, the most commonly purchased desiccant materials on the market show no significant change after dilution to saturation, making it impossible to determine their effectiveness. Utility Model Content

[0003] This application provides a color-changing desiccant packaging structure and a server packaging component to at least solve the problem in related technologies where the desiccant shows no obvious change after dilution and saturation, making it impossible to determine whether the desiccant is effective.

[0004] This application provides a color-changing desiccant packaging structure, comprising: a color-developing liquid; an inner packaging film enclosing the color-developing liquid; a separator film enclosing the inner packaging film, with a first containment space existing between the separator film and the inner packaging film; a first desiccant body located in the first containment space, wherein the first desiccant body is in powder form in a dry state and hardens into a crystalline form after absorbing moisture, and the crystalline first desiccant body pierces the inner packaging film; an outer packaging film enclosing the separator film, with a second containment space existing between the outer packaging film and the separator film; and a second desiccant body located in the second containment space, wherein the moisture absorption rate of the second desiccant body is higher than that of the first desiccant body.

[0005] This application also provides a server packaging, comprising: any of the color-changing desiccant packaging structures described above.

[0006] According to this application, the color-changing desiccant packaging structure is centered on the color-developing liquid and sequentially wrapped with an inner packaging film, a first desiccant body, a separator film, a second desiccant body, and an outer packaging film. After absorbing moisture, the first desiccant body hardens from a powdery state to a crystalline state, thereby piercing the inner packaging film and causing the color-developing liquid to flow outward, dyeing the outer packaging film and achieving the color change of the desiccant. During use, the moisture in the environment is absorbed by the second desiccant body through the outer packaging film of this color-changing desiccant packaging structure. As the second desiccant body becomes saturated with moisture, the first desiccant body begins to absorb moisture. After absorbing moisture, the first desiccant body hardens into crystalline blocks. The harder crystalline blocks of the first desiccant body come into contact with the inner packaging film. Combined with the external pressure during storage and transportation, the inner packaging film is punctured and ruptured by the crystalline blocks of the first desiccant body. The color-developing liquid inside the inner packaging film flows out and permeates onto the outer packaging film. When the outer packaging film turns color, it indicates that the color-changing desiccant packaging structure has become saturated with moisture, thus indicating that the color-changing desiccant packaging structure has failed and that the humidity of the environment where the color-changing desiccant packaging structure is located is high. This achieves an early warning and alert function, solving the problem in related technologies where there is no obvious change after the desiccant is diluted and saturated, making it impossible to determine whether the desiccant is effective. Furthermore, this application employs a double-layer desiccant structure, with the inner layer using a material that absorbs moisture and hardens into a crystalline form after absorbing moisture, and the outer layer using a material with superior moisture absorption. This ensures both the desiccant's color-changing indication function and the strong moisture absorption capacity of the color-changing desiccant packaging structure, enabling efficient moisture absorption.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0012] It should be noted that, in the description of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. The terms "first," "second," etc., in this application are used to distinguish similar objects and are not used to describe a specific order or sequence.

[0013] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] The embodiments of this application provide a color-changing desiccant packaging structure, which will be described in detail below with reference to the accompanying drawings.

[0015] Figure 1 A schematic diagram of the structure of a color-changing desiccant packaging structure 100 in one embodiment of this application is shown as an example. Figure 1 As shown, the color-changing desiccant packaging structure 100 of this application includes:

[0016] 10g of colorimetric reagent;

[0017] Inner packaging film 20, wrapping the above-mentioned color developer 10;

[0018] A separator 30 is used to wrap the inner packaging film 20, and a first accommodating space exists between the separator 30 and the inner packaging film 20.

[0019] The first desiccant body 40 is located in the first accommodating space. The first desiccant body 40 is in powder form when dry and hardens into crystalline form after absorbing moisture. The crystalline first desiccant body 40 pierces the inner packaging film 20.

[0020] An outer packaging film 50 wraps the aforementioned separator film 30, and a second accommodating space exists between the outer packaging film 50 and the aforementioned separator film 30;

[0021] The second desiccant body 60 is located in the second containment space, and the moisture absorption rate of the second desiccant body 60 is higher than that of the first desiccant body 40.

[0022] Through the above embodiments, in the color-changing desiccant packaging structure of this application, an inner packaging film, a first desiccant body, a separator film, a second desiccant body, and an outer packaging film are sequentially wrapped outward from the color-developing liquid as the center. After absorbing moisture, the first desiccant body hardens from powder to crystalline form, thereby piercing the inner packaging film and causing the color-developing liquid to flow outward, dyeing the outer packaging film and realizing the color change of the desiccant. During use, the color-changing desiccant packaging structure of this application allows moisture in the environment to be absorbed by the second desiccant body through the outer packaging film. As the second desiccant body becomes saturated with moisture, the first desiccant body begins to absorb moisture. After absorbing moisture, the first desiccant body hardens into crystalline form. The harder crystalline first desiccant body comes into contact with the inner packaging film, and with the external pressure during storage and transportation, the inner packaging film is punctured and ruptured by the crystalline first desiccant body. The color-developing liquid inside the inner packaging film flows out and permeates onto the outer packaging film. When the outer packaging film turns color, it indicates that the color-changing desiccant packaging structure has become saturated with moisture, thus indicating that the color-changing desiccant packaging structure has failed and that the ambient humidity of the environment where the color-changing desiccant packaging structure is located is high. This achieves an early warning and alert function, solving the problem in related technologies where there is no obvious change after the desiccant is diluted and saturated, making it impossible to determine whether the desiccant is effective. Furthermore, this application employs a double-layer desiccant structure, with the inner layer using a material that absorbs moisture and hardens into a crystalline form after absorbing moisture, and the outer layer using a material with superior moisture absorption. This ensures both the desiccant's color-changing indication function and the strong moisture absorption capacity of the color-changing desiccant packaging structure, enabling efficient moisture absorption.

[0023] In some exemplary embodiments, the inner packaging film 20 can be made of a thin film material that is highly water-resistant, tough, and not puncture-resistant. In this embodiment, the inner packaging film 20 can ensure the safe storage of the color developer 10 when the desiccant is not saturated, and can quickly release the color developer 10 once the desiccant is saturated and hardened, thus providing a color change warning.

[0024] In one alternative embodiment, the inner packaging film 20 is a polypropylene film. Polypropylene film possesses good water resistance and toughness, but is not puncture-resistant. This allows it to effectively encapsulate the color-developing liquid 10 within the color-changing desiccant packaging structure 100, while remaining easily puncturable after the first desiccant body 40 has hardened. The properties of the polypropylene film match the crystalline morphology of the first desiccant body 40 after hardening, further ensuring the reliability of the color-changing warning mechanism.

[0025] In other embodiments, other film materials with similar properties to polypropylene film, such as polyethylene film, can also be used as the material of the inner packaging film 20 to achieve the same effect as polypropylene film.

[0026] According to some embodiments of this application, the outer packaging film 50 can be made of a film material with excellent water vapor permeability, abrasion resistance, and toughness. In this embodiment, the outer packaging film 50 ensures that the desiccant is not damaged by external environmental factors during moisture absorption, and can respond promptly to humidity changes, providing early warning.

[0027] In some exemplary embodiments, the outer packaging film 50 is one of cotton paper, filter paper, non-woven fabric, and textured paper. Choosing cotton paper, filter paper, non-woven fabric, or textured paper as the outer packaging film 50 provides good water vapor permeability and abrasion resistance, effectively supporting the internal structure of the color-changing desiccant packaging structure 100 while allowing moisture from the environment to enter. The high permeability and abrasion resistance of the outer packaging film 50 ensure the moisture absorption performance and structural integrity of the color-changing desiccant packaging structure 100, enabling it to operate effectively in various environments.

[0028] In other embodiments, the same effect can be achieved by using other materials with high breathability and abrasion resistance, such as polyester fiber cloth, which are similar to cotton paper, filter paper, non-woven fabric, or textured paper.

[0029] Furthermore, to ensure the high air permeability of the outer packaging film 50, the outer packaging film 50 may have multiple mesh openings, which may be evenly or non-uniformly distributed. These mesh openings allow for the penetration of high-humidity external moisture. The diameter of the mesh openings may be smaller than the diameter of the second desiccant body 60.

[0030] Specifically, the material of the first desiccant body 40 is selected to be in powder form when dry and hardens into a crystalline form after absorbing moisture. The volume of the first desiccant body 40 in the crystalline form is larger than that in the powder form. In this embodiment, the first desiccant body 40 can harden and increase in volume after absorbing moisture, generating sufficient hardness to pierce the inner packaging film 20, release the color developing liquid 10, and achieve color change warning.

[0031] In some alternative solutions, the material of the first desiccant body 40 is gypsum powder or cement powder. In this technical solution, the main component of gypsum powder is calcium sulfate, which hardens into gypsum stone after absorbing moisture; the main component of cement powder is calcium oxide or calcium sulfate, which hardens into cement stone after absorbing moisture. Both gypsum stone and cement stone can puncture relatively thin film materials. Gypsum powder or cement powder is powdery in a dry state and hardens into crystalline form after absorbing moisture, making them ideal inner layer moisture-absorbing materials. The moisture-absorbing and hardening properties of gypsum or cement, combined with the properties of the inner packaging film 20, can continue to absorb moisture and puncture the inner packaging film 20 after the second desiccant body 60 is saturated, thereby triggering the warning mechanism. Furthermore, gypsum powder and cement powder are both low-cost materials, widely available and easily obtained in the prior art, which can make the overall cost of the color-changing desiccant packaging structure 100 of this application low.

[0032] In other embodiments, the same effect can be achieved by using other materials with similar hygroscopic hardening properties, such as certain types of salts or mineral powders, to address the early warning needs under different humidity environments.

[0033] According to some other embodiments of this application, the color developing solution 10 can be selected from low-cost, colored liquid materials. The use of the color developing solution 10 is based on the mechanism that the desiccant punctures the inner packaging film 20 after saturation and hardening, allowing the color developing solution 10 to contact and penetrate the outer packaging film 50, thereby changing its color.

[0034] In some exemplary embodiments, the color-developing solution 10 is a copper sulfate solution or a ferric sulfate solution. Copper sulfate or ferric sulfate solutions have the advantages of low cost and significant color-developing effect. They can rapidly penetrate the outer packaging film 50 after the desiccant saturates and punctures the inner packaging film 20, changing the color of the outer packaging film 50 and achieving a visual warning of color change indicating failure.

[0035] Specifically, most of the copper sulfate solutions mentioned above are blue solutions, but when the concentration of copper sulfate in the solution is high, the solution turns green. The ferric sulfate solutions mentioned above are yellow or brownish-yellow solutions.

[0036] In this application, the color of the outer packaging film 50 is different from the color developing liquid 10. The color difference provides a clear visual warning, making it immediately apparent whether the color-changing desiccant packaging structure 100 has failed, without the need for complex testing or judgment of the desiccant.

[0037] To further ensure a more obvious color development effect after dyeing with the color developer 10, the outer packaging film 50 is, for example, white or another light-colored material. Based on this, the color design of the color developer 10 is more flexible, allowing for the selection of different low-cost color-developing materials to achieve a balance between economy and functionality.

[0038] In practical applications, the material of the second desiccant body 60 can be selected from commercially available granular moisture-absorbing materials with good moisture absorption properties. The high moisture absorption rate of the second desiccant body 60 enables it to effectively control the humidity of the product packaging environment and prevent the product from being damaged by moisture.

[0039] In some embodiments, the material of the second desiccant body 60 is one of montmorillonite, calcium chloride, and bentonite. Montmorillonite, calcium chloride, or bentonite, as materials for the second desiccant body 60, possess excellent moisture absorption properties and environmentally friendly characteristics, effectively absorbing moisture even in low ambient humidity and protecting the product from moisture. Furthermore, the high moisture absorption rate of the second desiccant body 60 ensures that it can absorb most of the moisture, thereby intercepting the amount of water reaching the first desiccant body 40 and extending the service life of the color-changing desiccant packaging structure 100. Moreover, montmorillonite, calcium chloride, and bentonite are all inexpensive materials, widely available and readily accessible in the prior art, which allows for a lower overall cost of the color-changing desiccant packaging structure 100 of this application.

[0040] In some other embodiments of this application, the same effect can be achieved by using other materials with high moisture absorption properties, such as silica gel or certain types of molecular sieves, to solve the humidity control problem in specific environments.

[0041] In other alternatives, the separator 30 is made of a membrane material with good abrasion resistance, toughness and air permeability, which serves to block the mixing of the two moisture-absorbing materials, the first desiccant body 40 and the second desiccant body 60, while allowing water vapor to pass through.

[0042] For example, the puncture strength of the separator 30 is greater than that of the inner packaging film 20. This allows the separator 30 to effectively separate the two desiccant bodies, preventing the separator 30 from being punctured during the moisture absorption and hardening process of the first desiccant body 40, thus avoiding mutual interference between them during moisture absorption and further ensuring the normal operation of the color change warning mechanism of the color-changing desiccant packaging structure 100.

[0043] According to another optional embodiment of this application, the material of the separator 30 is the same as the material of the outer packaging film 50. In this embodiment, the material of the separator 30 is selected based on its required abrasion resistance and air permeability to ensure that the two desiccant components do not mix while allowing moisture to pass through. The material of the outer packaging film 50 must also possess the above characteristics, so the same material can be used to form the two film layers. In addition, using the same material for the separator 30 and the outer packaging film 50 simplifies the manufacturing process of the desiccant and reduces manufacturing costs.

[0044] For example, the separator 30 can be one of cotton paper, filter paper, non-woven fabric, or textured paper. Choosing cotton paper, filter paper, non-woven fabric, or textured paper as the separator 30 provides good water vapor permeability and abrasion resistance, effectively separating the first desiccant body 40 and the second desiccant body 60 while allowing moisture from the environment to enter. The high permeability and abrasion resistance of the separator 30 ensure the moisture absorption performance and structural integrity of the color-changing desiccant packaging structure 100, enabling it to work effectively in various environments.

[0045] Furthermore, to ensure the high air permeability of the aforementioned separator membrane 30, the separator membrane 30 may have multiple mesh openings, which may be uniformly or non-uniformly distributed. These mesh openings allow for the penetration of high-humidity external moisture. The diameter of the aforementioned mesh openings may be set to be smaller than the diameter of the aforementioned first desiccant body 40 in the dry state, and smaller than the diameter of the aforementioned second desiccant body 60.

[0046] Of course, the aforementioned separator membrane 30 may also be without the aforementioned air-permeable mesh.

[0047] In some embodiments, the volume of the first accommodating space is smaller than the volume of the second accommodating space. This results in a smaller amount of the first desiccant body 40 in the first accommodating space compared to the amount of the second desiccant body 60 in the second accommodating space. This allows the color-changing desiccant packaging structure 100 to absorb moisture as much as possible before it becomes discolored and expires, further extending the service life of the color-changing desiccant packaging structure 100.

[0048] Optionally, the thickness of the inner packaging film 20 is less than the thickness of the outer packaging film 50 and the thickness of the separator film 30. This thickness design further ensures that the first desiccant body 40 can easily puncture the inner packaging film 20 after hardening, thereby further ensuring that the color-changing desiccant packaging structure 100 can immediately change color after absorbing moisture saturation, thus improving the timeliness and accuracy of failure prediction and high ambient humidity warning. At the same time, the thickness of the outer packaging film 50 and the separator film 30 can provide sufficient structural strength and stability for the desiccant body.

[0049] In practical applications, the thickness ratio of the inner packaging film 20, the outer packaging film 50, and the separator film 30 can be adjusted to adapt to the hardening characteristics of different desiccant materials and the packaging requirements of different application scenarios.

[0050] According to a specific embodiment of this application, the thickness of the inner packaging film 20 is 0.05–0.1 mm. For example, the thickness of the inner packaging film 20 can be 0.05 mm, 0.06 mm, 0.07 mm, 0.08 mm, 0.09 mm, or 0.1 mm, etc. The thickness of the outer packaging film 50 is 0.3–0.5 mm. For example, the thickness of the outer packaging film 50 can be 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, or 0.5 mm, etc. The thickness of the separator film 30 is 0.3–0.5 mm. For example, the thickness of the separator film 30 can be 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, or 0.5 mm, etc. This embodiment, through precise film thickness design, can further ensure the stability of the desiccant structure and the reliability of the early warning mechanism. Specifically, the inner packaging film 20 with a thickness of 0.05 to 0.1 mm ensures that it can be easily punctured after the first desiccant body 40 has hardened, while the outer packaging film 50 with a thickness of 0.3 to 0.5 mm and the separator film 30 with a thickness of 0.3 to 0.5 mm provide sufficient structural strength and stability for the color-changing desiccant packaging structure 100 as a whole, while allowing water vapor to pass through these two layers of film.

[0051] The color-changing desiccant packaging structure 100 described in this application has a simple structure, uses low-cost and environmentally friendly materials, and is easy to mass-produce and use. This color-changing desiccant packaging structure can solve the problem that montmorillonite and calcium chloride desiccants cannot determine whether they have become saturated with water and have failed, and it also solves the problem that color-changing silica gel desiccants are expensive and the materials are not environmentally friendly.

[0052] To enable those skilled in the art to better understand the technical solution of this application, the specific structure and color-changing principle of the color-changing desiccant packaging structure of this application will be described in detail below with reference to specific embodiments.

[0053] This embodiment provides a color-changing desiccant packaging structure, which consists of a color-developing liquid, an inner packaging film, a separator film, a first desiccant body, a second desiccant body, and an outer packaging film. The outer packaging film acts as a carrier, enclosing the color-developing liquid, inner packaging film, separator film, first desiccant body, and second desiccant body internally. The outer packaging film possesses excellent water vapor permeability, abrasion resistance, and toughness. The outer packaging film can be made of cotton cloth and is white in color to facilitate color development. The first and second desiccant bodies are carried inside the outer packaging film and separated into two moisture-absorbing areas from the outside to the inside by the separator film. The second desiccant body is located in the outer moisture-absorbing area, and the first desiccant body is located in the inner moisture-absorbing area. The material of the second desiccant body can be a commercially available granular moisture-absorbing material with good moisture absorption properties, specifically montmorillonite. The material of the first desiccant body is a powdery form in its dry state, which crystallizes after absorbing moisture; the material can be gypsum powder or cement powder. Gypsum powder absorbs water to form hardened gypsum stone, and cement powder absorbs water to form hardened cement stone. Gypsum stone or cement stone can puncture thin film materials. The separator membrane is made of a membrane material with good wear resistance, toughness, and breathability. The material can be the same as the outer packaging membrane material to prevent the mixing of the two hygroscopic components. The inner packaging membrane is placed inside the inner moisture-absorbing area and is made of a membrane material with high water resistance and toughness but not puncture resistance; the material can be polypropylene film. The color developing solution is placed inside the inner packaging membrane and is made of a low-cost, colored liquid material; specifically, the color developing solution can be copper sulfate solution or ferric sulfate solution.

[0054] The color-changing principle of the aforementioned color-changing desiccant packaging structure is as follows: During use, moisture in the environment permeates through the outer packaging film and is first absorbed by the second desiccant in the outer moisture-absorbing area. As the second desiccant in the outer moisture-absorbing area becomes saturated, the first desiccant in the inner moisture-absorbing area begins to absorb water. The first desiccant in the inner moisture-absorbing area forms hard crystals after absorbing water. When these hard crystals come into contact with the thinner inner packaging film, the inner packaging film is punctured and ruptured under external pressure during storage and transportation. The color-developing liquid inside the inner packaging film flows out and permeates the outer packaging film. When the outer packaging film turns color, it indicates that the color-changing desiccant packaging structure is saturated, signifying that the packaging structure has failed and the humidity of the product packaging environment is too high, thus providing an early warning and alert function.

[0055] The low-cost, environmentally friendly color-changing desiccant packaging structure proposed in this application possesses excellent hygroscopic properties and a color-changing function. When the packaging structure becomes saturated with moisture, it changes color, serving as an early warning and alert. This helps prevent the use of ineffective desiccants during packaging, which could lead to product rust, short circuits, and other problems. Simultaneously, the color-changing desiccant packaging structure can detect excessive moisture levels inside the packaging during storage and transportation, providing a warning. Furthermore, the proposed color-changing desiccant packaging structure is simple in structure, uses low-cost and environmentally friendly materials, and is easy to mass-produce.

[0056] Embodiments of this application also provide a server package comprising any of the above-described color-changing desiccant packaging structures.

[0057] In the above embodiments, by applying the aforementioned color-changing desiccant packaging structure to server packaging, a desiccant structure capable of providing a failure warning through color change is provided. Specifically, during use, moisture in the environment is absorbed by the second desiccant body through the outer packaging film of the color-changing desiccant packaging structure. As the second desiccant body becomes saturated with moisture, the first desiccant body begins to absorb moisture. After absorbing moisture, the first desiccant body hardens into a crystalline form. The harder crystalline first desiccant body comes into contact with the inner packaging film, and with the external pressure during storage and transportation, the inner packaging film is punctured and ruptured by the crystalline first desiccant body. The color-developing liquid encased inside the inner packaging film flows out and permeates onto the outer packaging film. When the outer packaging film turns color, it indicates that the color-changing desiccant packaging structure has become saturated with moisture, thus indicating that the color-changing desiccant packaging structure has failed and that the ambient humidity in which the color-changing desiccant packaging structure is located is high. This achieves the warning and alert function, solving the problem in related technologies where there is no obvious change after the desiccant is diluted and saturated, making it impossible to determine whether the desiccant is effective. Furthermore, this application employs a double-layer desiccant structure. The inner layer uses a material with hygroscopic properties that hardens into a crystalline form after absorbing moisture, while the outer layer uses a material with even better hygroscopic properties. This design ensures both the desiccant's color-changing indication function and the strong moisture absorption capacity of the color-changing desiccant packaging structure, achieving efficient moisture absorption. The color-changing mechanism of this desiccant packaging structure, combined with the humidity control requirements of server packaging, ensures the product's moisture protection during storage and transportation. It effectively prevents the use of expired desiccants in server packaging, which could lead to the desiccant failing to achieve its intended drying effect and causing adverse phenomena such as rusting or short circuits in the server, thus improving product reliability and lifespan. Moreover, the color-changing function of the aforementioned desiccant packaging structure can detect whether the humidity inside the packaging is too high during product storage and transportation, thus serving as a warning.

[0058] Servers provide computing or application services to other client machines (such as PCs, smartphones, ATMs, and even large equipment like train systems) on a network. Servers possess high-speed CPU processing power, long-term reliable operation, powerful I / O external data throughput, and better scalability. Generally, servers are capable of responding to service requests, providing services, and ensuring service availability, depending on the services they provide. As electronic devices, servers have a complex internal structure, but it is not significantly different from the internal structure of ordinary computers, including components such as CPU, hard drive, memory, system, and system bus. Server products contain a large amount of metal in their electronic components and integrated circuits, commonly containing copper, tin, nickel, zinc, aluminum, chromium, lead, and mercury, existing in various forms as elements and compounds; physical forms also vary, including alloys, plating, etc. Some components even contain precious metals. High humidity promotes metal corrosion and rust, leading to short circuits and damage to components and integrated circuits. Excessive ambient humidity can severely impact products. Furthermore, in high humidity environments, the mechanical properties of packaging significantly decrease. Rain, snow, dew, waves, and accidental water spills during product storage and transportation can all create high-humidity environments for the product. Therefore, proper moisture-proofing of both the product and its packaging is crucial. The aforementioned color-changing desiccant packaging structure effectively protects the server from moisture.

[0059] Specifically, the aforementioned color-changing desiccant packaging structure can be applied to processes in high-humidity environments such as server storage, transportation, and packaging. While ensuring sufficient drying of the server, it also provides early warning and alert functions when the desiccant becomes saturated with moisture, preventing corrosion and rust of high-precision electronic components and circuits in the server, which could lead to short circuits and damage to components and integrated circuits.

[0060] In other embodiments, the above-described color-changing desiccant packaging structure can also be applied to the packaging of other electronic devices or sensitive products to address humidity control and early warning needs in specific environments.

[0061] The foregoing has provided a detailed description of a color-changing desiccant packaging structure and a server packaging component provided in this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are merely for the purpose of helping to understand the solution and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this application.
