Description

Technical Field

[0001] The present invention relates to the technical field of galvanized sheets, and specifically to an environmentally friendly anti-corrosion sound-insulating galvanized sheet. Background Art

[0002] A galvanized sheet refers to a steel sheet with a layer of zinc plated on its surface. Galvanizing is an economical and effective rust prevention method that is often adopted, and about half of the world's zinc production is used for this process.

[0003] After searching, the patent publication number CN221779790U "A Galvanized Steel Sheet" is for facilitating the connection between two galvanized steel sheets. Through the setting of T-shaped ridges and T-shaped grooves, the left and right directions of the two galvanized steel sheet bodies are limited. Also, through the setting of an elastic clamping component, the front and back directions of the two galvanized steel sheet bodies are limited and fixed, enabling the two galvanized steel sheets to be spliced and used. The operation is simple and the firmness is strong. Although the operation is convenient and can increase the firmness, the function is single and it does not have the effect of sound insulation. Therefore, an environmentally friendly anti-corrosion sound-insulating galvanized sheet is proposed. Summary of the Invention

[0004] Technical Problem to be Solved In view of the deficiencies of the prior art, the present invention provides an environmentally friendly anti-corrosion sound-insulating galvanized sheet.

[0005] Technical Solution To achieve the above-mentioned solution purpose, the present invention provides the following technical solution: An environmentally friendly anti-corrosion sound-insulating galvanized sheet, including an upper plate and a lower plate. Two first hollow blocks are installed on the inner surface of the upper plate, and two second hollow blocks are installed on the inner surface of the lower plate. Trapezoidal seats and inner hole seats are installed on both the upper plate and the lower plate. An upper wedge tip and a lower wedge tip are respectively provided on the upper plate and the lower plate. The interiors of the first hollow block and the second hollow block are both hollow.

[0006] Further, a groove is opened at the top end of the second hollow block, and a protrusion is provided at the bottom end of the protrusion.

[0007] Further, trapezoidal holes are opened on the outer surfaces of both the upper plate and the lower plate.

[0008] Further, the upper wedge tip and the lower wedge tip are located between the two trapezoidal seats and the inner hole seats.

[0009] Further, L-shaped grooves are opened on both sides of the upper plate and the lower plate, and connecting insertion rods are sleeved inside the L-shaped grooves.

[0010] Further, the number of the connecting insertion rods is two, and rectangular grooves are opened on the inner sides of the two connecting insertion rods.

[0011] Furthermore, circular grooves are provided at the front and rear ends of the upper plate and the lower plate, and sealing plates are installed inside the circular grooves.

[0012] Furthermore, there are two sealing plates, and the two sealing plates are of the same size.

[0013] Beneficial Effects Compared with the prior art, the present invention provides an environmentally friendly and corrosion-resistant sound-insulating galvanized sheet, which has the following beneficial effects: 1. This environmentally friendly and corrosion-resistant sound-insulating galvanized plate is provided with a trapezoidal seat, an inner hole seat, an upper wedge and a lower wedge. At this time, the propagation path of the sound will be separated, thereby changing the path of the sound propagation and consuming the energy of its propagation. The sound entering the inner hole seat is due to the smaller opening of the upper end of the inner hole seat. When the opening is small, when the sound propagates through the opening, due to the limitation of the propagation path and the divergence of the sound waves, the energy loss of the sound in the propagation process will increase, thereby accelerating the attenuation of the sound. In addition, the air vibration at the small opening will also be limited, which will reduce the radiation efficiency of the sound, further leading to the weakening of the sound intensity. At the same time, the top of the inner hole seat The opening is small, and the material formed around the top is thicker. There are cavities around the top of the inner hole seat to absorb the sound completely and perform sound absorption to the greatest extent. The upper and lower wedge tips are located between the two trapezoidal seats and the inner hole seat. The upper and lower wedge tips will work together with the trapezoidal seats and the inner hole seat to make the sound absorption effect better. At the same time, the upper and lower wedge tips are made of glass wool. The internal fibers of the glass wool are fluffy and interlaced, and there are a large number of tiny pores, which can achieve a sound-absorbing effect. Glass wool has good sound absorption and noise reduction effects: as a porous sound-absorbing material, glass wool can absorb a large amount of sound energy in the room, reduce reverberation time, and reduce indoor noise.

[0014] 2. This environmentally friendly, corrosion-resistant sound-insulating galvanized sheet has a passivation treatment on the surfaces of the upper and lower sealing plates, and a dense compound film is generated on the surface of the galvanized layer. This film can tightly cover the surface of the galvanized layer, preventing external corrosive media from directly contacting the metal matrix, thereby effectively preventing the occurrence of corrosion.

[0015] 3. This environmentally friendly and corrosion-resistant sound-insulating galvanized plate connects the upper plate and the lower plate together by connecting the rods. Finally, the front ends of the upper plate and the lower plate are provided with circular grooves. At this time, the front ends of the upper plate and the lower plate are closed by the sealing plate, which is convenient to operate and increases its firmness. At the same time, before packaging, the outer surfaces of the connecting rods and the sealing plate are coated with epoxy resin adhesive to make the adhesion more firm and will not produce gaps to affect the sound insulation effect. At the same time, the epoxy resin adhesive has a certain degree of corrosion resistance. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Please refer to Figures 1 to 5 The present invention provides an environmentally friendly and corrosion-resistant sound-insulating galvanized sheet, which includes an upper plate 1 and a lower plate 2. During use, due to different application methods, the existing galvanized sheets have different functions. Nowadays, during the use of galvanized sheets, they need to have the functions of corrosion resistance and sound insulation. Therefore, an environmentally friendly and corrosion-resistant sound-insulating galvanized sheet is proposed. First, the operator sets trapezoidal holes 3 on the outer surface of the upper plate 1. The trapezoidal holes 3 have a certain gradient, and this design is also adopted on the lower plate 2. When sound is transmitted to the surface of the sheet, it will pass through the surface of the trapezoidal holes 3 and be consumed in a gradient by the shape of the trapezoidal holes 3, thereby reducing the energy of sound transmission and achieving the purpose of preliminary sound attenuation. At the same time, galvanizing treatment is carried out on the outer surfaces of the upper plate 1, the lower plate 2 and the trapezoidal holes 3. A dense barrier layer will be formed on the surface of the galvanized layer, which can effectively isolate the direct contact between air, moisture and other corrosive substances and the steel plate matrix, thereby preventing the internal sheet from being oxidized and corroded. At the same time, during the production process, the surfaces of the upper plate 1 and the lower plate 2 are passivated, and a dense compound film is formed on the surface of the galvanized layer. This film can closely cover the surface of the galvanized layer, preventing the direct contact between external corrosive media and the metal matrix, thereby effectively preventing corrosion from occurring.

[0024] Next, in order to more effectively isolate the sound, a trapezoidal seat 4 is installed on the inner surface of the upper plate 1. An inner hole seat 5 is installed inside the trapezoidal seat 4. There is a certain distance between the trapezoidal seat 4 and the inner hole seat 5. At this time, the sound propagation path will be separated, thereby changing the sound propagation path and further consuming the energy of its propagation. For the sound entering the inner hole seat 5, since the upper port of the inner hole seat 5 is smaller and the opening is small, when the sound propagates through the opening, due to the limitation of the propagation path and the divergence of the sound wave, the energy loss during the sound propagation will increase, thereby accelerating the attenuation of the sound. In addition, the air vibration at the small opening is also restricted, resulting in a decrease in the sound radiation efficiency and further weakening the sound intensity. At the same time, the top opening of the inner hole seat 5 is small, and the material formed around the top is thick. A cavity is provided around the top of the inner hole seat 5, thereby absorbing the sound completely and performing sound insulation treatment to the greatest extent.

[0025] Next, in order to make the sound deadening treatment more effective, the operator installs an upper wedge tip 6 on the inner surface of the upper plate 1 and a lower wedge tip 7 on the inner surface of the lower plate 2. The upper wedge tip 6 and the lower wedge tip 7 are located between the two trapezoidal seats 4 and the inner hole seat 5. The upper wedge tip 6 and the lower wedge tip 7 will act together with the trapezoidal seats 4 and the inner hole seat 5 to achieve better sound absorption effect. At the same time, the upper wedge tip 6 and the lower wedge tip 7 are made of glass wool. The internal fibers of the glass wool are fluffy and intertwined, with a large number of tiny pores, thus achieving the sound absorption effect. Glass wool has good sound absorption and noise reduction effects: As a porous sound-absorbing material, glass wool can absorb a large amount of sound energy in the room, reduce the reverberation time, and reduce indoor noise. For example, in large spaces such as gymnasiums and workshops, using sound-absorbing bodies made of glass wool can effectively absorb sound and improve the acoustic performance of the space. High temperature resistance and corrosion resistance: Glass wool has relatively high heat resistance and can withstand temperatures up to 500°C or even higher. At the same time, it is relatively stable to general chemical substances and is not easily corroded, and can maintain its performance in a variety of harsh environments. Third, good economic performance and high cost performance: Glass wool is a thermal insulation material with a relatively low price and can achieve high thermal insulation performance at low cost. Compared with other thermal insulation materials on the market, it has more economic advantages while ensuring performance. Convenient construction: Glass wool is soft in texture, has good elasticity and adaptability, is easy to cut and install, can be cut arbitrarily according to needs, and is suitable for large-area laying. This not only improves the construction efficiency but also reduces the construction cost. Fourth, strong durability and not easy to age: The raw material of glass wool, glass, has high durability and will not deteriorate over time. In long-term use, it can maintain stable performance and reduce the frequency of maintenance and replacement. Resistance to insect infestation and mildew: Glass wool will not breed bacteria and mildew and will not pose a health risk to the living environment. This enables it to maintain a good state of use for a long time in humid environments and other environments. Fifth, good environmental performance and recyclable: Glass wool can be made from recycled glass, meeting the requirements of sustainable development. This not only reduces the consumption of natural resources but also reduces the generation of waste. Non-toxic and harmless: The International Agency for Research on Cancer (IARC) has proven that glass wool has a low carcinogenic risk and is a material friendly to the environment and human health.

[0026] During the assembly of the soundproof board, in order to seal the upper board 1 and the lower board 2 as a whole, two first hollow blocks 8 are carefully installed on the inner surface of the upper board 1. The interiors of these two first hollow blocks 8 are in a sealed vacuum environment. This unique design can effectively isolate the transmission of sound because sound cannot be effectively transmitted in a vacuum, thus laying a solid foundation for the soundproof performance of the entire structure. At the same time, a relatively soft protrusion 9 is fixedly installed at the bottom end of the first hollow block 8. This texture selection ensures a certain elasticity without being too soft to affect the stability of the structure. On the inner surface of the lower board 2, two second hollow blocks 10 are installed. Their interiors are also hollow, and in order to perfectly cooperate with the protrusion 9 at the bottom end of the first hollow block 8, grooves 11 are opened at the top ends of the two second hollow blocks 10. When the operator assembles the upper board 1 and the lower board 2, the cooperation between the first hollow block 8 and the second hollow block 10 is seamless. The protrusion 9 of the first hollow block 8 will accurately snap into the groove 11 at the top end of the second hollow block 10, thus firmly installing the upper board 1 and the lower board 2 together to form a whole.

[0027] During the clamping process of the upper board 1 and the lower board 2, the trapezoidal seats 4 and the inner hole seats 5 installed on them also play a crucial role. The trapezoidal seats 4 and the inner hole seats 5 on the upper board 1 and the trapezoidal seats 4 and the inner hole seats 5 on the lower board 2 will accurately converge into a whole with their tails connected and are in a mirror-symmetrical form during assembly. This ingenious structural design enables sound to be effectively blocked and absorbed whether it propagates from the direction of the upper board 1 or the lower board 2, thus playing an excellent sound-absorbing role. When the sound is first absorbed by the trapezoidal seats 4 and the inner hole seats 5, it will not stop there, but will be further subjected to deeper sound-absorbing treatment by another trapezoidal seat 4 and inner hole seat 5. This dual sound-absorbing mechanism greatly improves the soundproof effect of the entire structure, bringing the soundproof performance to a new level.

[0028] At the same time, the upper wedge tips 6 and the lower wedge tips 7 installed on the upper board 1 and the lower board 2 are also misaligned and distributed between the two trapezoidal seats 4 and the inner hole seats 5, further enhancing the sound-absorbing effect. The special shapes and arrangement methods of the upper wedge tips 6 and the lower wedge tips 7 can effectively capture and absorb sounds of different frequencies, ensuring that sounds are absorbed and consumed as much as possible during propagation, thereby minimizing the sound transmission and achieving the ideal soundproof purpose. This innovative soundproof board assembly and application solution not only shows ingenuity in structural design but also performs excellently in soundproof performance, providing strong support and guarantee for solving the problem of noise pollution.

[0029] After the upper plate 1 and the lower plate 2 are snap-connected together, the operator needs to perform fine-tuning. They carefully move the upper plate 1 or the lower plate 2 so that the protrusion 9 on the plate slides smoothly inside the groove 11. This fine-tuning operation requires extremely high precision and skills. The operator, relying on rich experience and keen observation, continuously adjusts the position of the plate until the length between the upper plate 1 and the lower plate 2 reaches the optimal matching state.

[0030] To further enhance the connection firmness between the upper plate 1 and the lower plate 2, the operator opens L-shaped grooves on both of their sides. The design of these L-shaped grooves has undergone careful calculation and strict testing to ensure a perfect fit with the connecting plug 12. The operator picks up the connecting plug 12 and accurately inserts it into the inside of the L-shaped groove, thereby tightly connecting the upper plate 1 and the lower plate 2 together. On the inner surface of the connecting plug 12, the operator has pre-set rectangular grooves 13, and these rectangular grooves 13 provide an ideal space for subsequent sound absorption treatment. The operator fills the inside of the rectangular groove 13 with high-quality sound insulation material. This material not only has excellent sound absorption performance but also can effectively reduce the weight of the entire structure, thus achieving the purpose of weight reduction. During the filling process, the operator ensures that the sound insulation material is evenly distributed in the rectangular groove 13, without gaps or overfilling, to achieve the best sound absorption effect and structural stability.

[0031] On the outer surface of the connecting plug rod 12, the operator evenly applied a layer of epoxy resin adhesive. This adhesive is renowned for its excellent bonding performance and good weather resistance, and can remain stable under different environmental conditions. When the connecting plug rod 12 is inserted into the L-shaped groove and the adhesive is applied, it not only makes the upper plate 1 and the lower plate 2 more firmly integrated as a whole, but also effectively prevents gaps from appearing at the connection, thereby avoiding the influence on the sound insulation effect. As the adhesive cures, it forms a strong bonding layer, ensuring a tight bond between the adhered objects, making the entire assembly structure both firm and aesthetically pleasing, fully meeting the requirements of high-quality standards, and providing reliable guarantees for subsequent use and transportation. Epoxy resin has small physical shrinkage and high stability: During the curing process, the shrinkage rate is low, generally between 1% of the upper plate and 2% of the lower plate. After curing, the volume change is small, and it can maintain good shape and dimensional stability, reducing internal stress and deformation caused by shrinkage. Chemical corrosion resistance: It has good tolerance to many chemical substances such as acids, alkalis, salts, etc., is not easily corroded, can be used in a variety of chemical environments, and maintains bonding performance and material integrity. Electrical insulation: It has excellent electrical insulation performance, high resistivity, and low dielectric constant, and can be used for insulating bonding of electronic and electrical equipment to ensure the safe operation of the equipment. Water and oil resistance: It can still maintain good bonding performance in water and oil media, is not easily eroded by water or oil, and is suitable for humid environments or occasions that need to come into contact with oil. It does not contain volatile solvents: During the curing process, it does not release a large amount of volatile organic compounds, reducing environmental pollution and harm to human health, and also avoiding defects and safety hazards caused by solvent volatilization.

[0032] Finally, the operator is dressed in clean work clothes. The upper plate 1 and the lower plate 2 are carefully processed through multiple complex processes. The front end is specially provided with round grooves 15. The dimensions and positions of these round grooves 15 have been precisely calculated and strictly quality inspected to ensure the accuracy and stability of the subsequent encapsulation process. At this time, the operator skillfully picks up the sealing plate 14. This sealing plate 14 is a component specially designed to close the front end of the plate. Its material and strength are perfectly matched with the plate. The round rods carefully set on the sealing plate 14 perfectly fit the round grooves 15 at the front ends of the upper plate 1 and the lower plate 2. When the sealing plate 14 is installed in place, the round rods are precisely inserted into the round grooves 15. This ingenious design can not only effectively prevent the plate from shifting or loosening during use, but also provide strong support and stability for the entire structure.

[0033] During the encapsulation process of the upper plate 1 and the lower plate 2, the operator first applied a meticulous epoxy resin adhesive to the inner surface of the sealing plate 14. They used professional application tools to ensure that the adhesive evenly covered every corner of the sealing plate 14, without any excess accumulation or missed blank areas. This adhesive has strong adhesion and excellent weather resistance, and can remain stable under different environmental conditions, providing a solid guarantee for subsequent encapsulation. When the sealing plate 14 is installed on the plate, the adhesive starts to work, tightly bonding the sealing plate 14 to the plate to form a firm whole. After a period of curing, this bonding effect will be more significant, ensuring the stability and reliability of the entire encapsulation structure, enabling the final product to meet the requirements of high-quality standards, and providing a reliable guarantee for subsequent use and transportation.
