Description

Technical Field

[0001] This utility model relates to a modular rust-proof flexible packaging device for high humidity environments, belonging to the field of packaging technology. Background Technology

[0002] In modern society, metal corrosion causes significant economic losses and safety hazards across various sectors. Especially in high-humidity environments, the rate of metal corrosion accelerates considerably, making the use of rust inhibitors and desiccants common methods.

[0003] Chinese Patent Publication No. CN204280213U discloses a moisture-indicating desiccant, comprising a desiccant and at least one humidity indicator printed on the outer wall of the desiccant bag. The desiccant and humidity indicator are integrated; the humidity value inside the sealed packaging bag is immediately known by the color change of the humidity indicator, thereby determining whether the desiccant has failed and whether it needs to be replaced, ensuring that the product inside the sealed packaging bag is not affected or damaged by moisture.

[0004] The aforementioned patent uses a color-changing indicator printed on the outer wall of the desiccant bag to display the current humidity value, determining whether the desiccant has failed and then replacing it. However, this method is inefficient, difficult to implement, and the integrated packaging of the desiccant and indicator makes it impossible to adjust the configuration according to environmental changes, thus failing to achieve maximum rust prevention.

[0005] Therefore, it is necessary to improve the existing modular rust-proof flexible packaging devices for high-humidity environments. Utility Model Content

[0006] The purpose of this invention is to provide a modular rust-proof flexible packaging device for high humidity environments, so as to solve the problems mentioned in the background art.

[0007] The technical solution of this utility model is as follows:

[0008] A modular rust-proof flexible packaging device for high humidity environments includes a flexible packaging body, a rust-inhibiting module, and a drying monitoring module. The flexible packaging body encloses the rust-inhibiting module and the drying monitoring module. The rust-inhibiting module and the drying monitoring module form two cavities through a magnetic separator embedded between them. The surfaces of the two cavities are provided with at least one hole. The rust-inhibiting module and the drying monitoring module can be disassembled and connected through the magnetic separator.

[0009] Furthermore, the cavities of both the rust-inhibiting module and the drying monitoring module are made of soft rubber.

[0010] Furthermore, the cavity of the rust-inhibiting module contains a VCI corrosion inhibitor powder packet.

[0011] Furthermore, the dryness monitoring module includes a humidity detection card and a desiccant compartment. The humidity detection card is affixed to the surface of the cavity of the dryness monitoring module, and the desiccant compartment is located inside the cavity of the dryness monitoring module. The humidity detection card is made of cobalt chloride-silica gel composite material and has a three-color warning zone, wherein: when the relative humidity is less than 60%RH, the humidity detection card displays green; when the relative humidity is between 60%RH and 90%RH, the humidity detection card displays yellow; and when the relative humidity is greater than 90%RH, the humidity detection card displays red.

[0012] Furthermore, the hole is 20 mm long and 100 mm wide.

[0013] This utility model has the following beneficial effects:

[0014] The rust-inhibiting module and the drying monitoring module are connected and disassembled by a magnetic separator, facilitating the replacement of the VCI corrosion inhibitor powder pack in the rust-inhibiting module and the drying chamber in the drying monitoring module. This allows for convenient replacement of the desiccant and corrosion inhibitor within the packaging device, reducing the rate of metal corrosion in high-humidity environments. The rust-inhibiting module uses the VCI corrosion inhibitor powder pack in its loading chamber. The VCI corrosion inhibitor powder pack evaporates in the enclosed space, forming a gaseous protective film that is evenly adsorbed onto the metal surface, reducing the occurrence of corrosion reactions and lowering the metal corrosion rate. The drying monitoring module is equipped with various desiccants that continuously absorb moisture within the packaging, maintaining a relatively dry environment and reducing the likelihood of metal corrosion. A humidity monitoring card is used, with the color indicating the humidity inside the device. This allows for external monitoring of the internal humidity within the packaging device. Both the rust-inhibiting module and the drying monitoring module have at least one hole on their cavity surfaces to promote VCI molecule diffusion and water molecule aggregation, and also facilitate the quick replacement of the VCI corrosion inhibitor pack and desiccant chamber, further reducing the metal corrosion rate.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0020] Please refer to Figures 1 to 2 A modular rust-proof flexible packaging device for high humidity environments includes a flexible packaging body 1, a rust-inhibiting module 2, and a drying monitoring module 3. The flexible packaging body 1 encloses the rust-inhibiting module 2 and the drying monitoring module 3. The rust-inhibiting module 2 and the drying monitoring module 3 form two cavities through a magnetic separator 4 embedded between them. The surfaces of the two cavities are provided with at least one hole 5. The rust-inhibiting module 2 and the drying monitoring module can be disassembled and connected through the magnetic separator.

[0021] The flexible composite membrane is made of PTFE / PE breathable and waterproof composite membrane, which is a transparent composite membrane. The PTFE (polytetrafluoroethylene) layer is located on the outside and has a thickness of 30-50 mm. PTFE material has high stability and low coefficient of friction, and can resist various chemical erosions in high humidity environments. The PE (polyethylene) layer is located on the inside and has a thickness of 20-30 mm. It has good flexibility and certain mechanical strength. The two layers combined have both breathable and waterproof properties.

[0022] The cavities of both the rust-inhibiting module 2 and the drying monitoring module 3 are made of soft rubber to prevent damage to the flexible packaging body 1 during packaging and transportation.

[0023] The rust-inhibiting module 2 contains a VCI corrosion inhibitor powder packet 8. The VCI corrosion inhibitor powder packet 8 is double-layered, with an inner layer of kraft paper and an outer layer of breathable non-woven fabric with a mesh size of 60-80 mesh. This prevents leakage of the VCI vapor phase corrosion inhibitor while ensuring the effective volatilization of the inhibitor components. Users accurately calculate and fill an appropriate amount of VCI vapor phase corrosion inhibitor according to the packaging size and required protective effect. The VCI vapor phase corrosion inhibitor is a composite product containing fatty acid salts and aromatic acid salts. After volatilization, these components can adsorb onto the metal surface, forming a dense protective film that blocks oxygen and moisture from contacting the metal, inhibiting the rust reaction. After filling, the opening of the corrosion inhibitor powder packet is sealed using a heat-sealing process. The heat-sealing temperature is controlled at 130-150℃ for 2-4 seconds to ensure a firm seal and prevent corrosion inhibitor leakage.

[0024] The dryness monitoring module 3 includes a humidity detection card 6 and a desiccant compartment 7. The humidity detection card 6 is affixed to the surface of the cavity of the dryness monitoring module 3. The desiccant compartment 7 is located inside the cavity of the dryness monitoring module 3 and is used to hold desiccant, including but not limited to color-changing silica gel and magnesium chloride. The desiccant compartment 7 is made of breathable non-woven fabric (50-70 mesh) in a bag shape as the outer shell, and is filled with desiccant, including but not limited to silica gel desiccant particles with a particle size of 3-5 mm. The amount used is reasonably adjusted according to the packaging size, usually 100-1000 particles per 1 cm³. g. Desiccant; The humidity detection card 6 is made of cobalt chloride-silica gel composite material. The color of the humidity detection card 6 is adjusted by adding calcium chloride, methyl red, or bromocresol green to the cobalt chloride-silica gel composite material, achieving a three-color warning zone. The colors of the three-color warning zone are arranged from top to bottom: green, yellow, and red. Specifically: when the relative humidity is less than 60%RH, the humidity detection card 6 displays green, indicating that the desiccant is working well; when the relative humidity is between 60%RH and 90%RH, the humidity detection card 6 displays yellow, indicating that the desiccant has partially absorbed moisture and subsequent changes need to be monitored; when the relative humidity is greater than 90%RH, the humidity detection card 6 displays red, indicating that the user needs to immediately replace the desiccant compartment 7. The desiccant monitoring module 3 should be removed and a new desiccant monitoring module 3 installed, or a new desiccant compartment 7 can be replaced through the hole 5.

[0025] The hole 5 is 20 mm long and 100 mm wide. The hole 5 is used to facilitate the diffusion or aggregation of VCI molecules or water molecules, and to facilitate the replacement of VCI corrosion inhibitor powder pack 8 and desiccant compartment 7.

[0026] Working principle of this utility model:

[0027] When performing rust prevention treatment on metal objects, first place the metal product on the unfolded flexible packaging body 1. Cut the flexible packaging body 1 appropriately according to the shape and size of the metal to ensure it tightly wraps or adheres to the metal object. Then, magnetically attach the pre-fabricated rust-inhibiting module 2 and the drying monitoring module 3 to a suitable position inside the flexible packaging body 1, ensuring effective evaporation of the corrosion inhibitor and easy observation of the humidity detection card 6 on the drying monitoring module 3. After completing the above operations, seal the flexible packaging body 1, using methods such as heat sealing or cable ties, to ensure a good seal.

[0028] Users should conduct regular inspections of the packaging equipment based on actual conditions, increasing the inspection frequency in high-humidity and harsh environments, paying particular attention to the color of the humidity detection card 6 on the drying monitoring module 3. If the detection card displays red, immediately initiate the desiccant replacement procedure by disassembling the drying monitoring module 3 and replacing the desiccant chamber 7, or by removing the saturated desiccant chamber 7 through the holes 5 on the surface of the drying monitoring module 3 and refilling it with a new one. Simultaneously check the condition of the rust-inhibiting module 2; if the humidity is high, this module can also be replaced to ensure the entire packaging equipment maintains good rust prevention performance and effectively protects metal objects from corrosion in high-humidity environments.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
