Description

Technical Field

[0001] This utility model relates to the field of plastic pellet technology, specifically to a plastic pellet with good compressive strength and corrosion resistance. Background Technology

[0002] Plastics, as a large and diverse family of materials, are composed of a rich array of elements, primarily carbon, oxygen, hydrogen, nitrogen, and other organic or inorganic elements. In the initial manufacturing stage, they exist as a molten liquid with excellent fluidity. Mechanical heating can melt them, and applying pressure allows them to flow within molds or other spaces, filling specific shaped areas. Upon cooling, they solidify into a finished solid product. It is precisely this liquid-to-solid transformation characteristic that allows for the creation of countless shapes to meet the diverse needs of various industrial and everyday applications.

[0003] In applications requiring high pressure resistance, such as support components for heavy machinery and load-bearing plastic components in building structures, ordinary plastic granules are prone to deformation or even breakage due to their poor compressive strength. This threatens the stability of the entire structure and seriously affects the product's service life and safety. At the same time, in environments with corrosive substances, such as chemical, marine, and food processing industries, if plastic granules lack sufficient corrosion resistance, they will be eroded by corrosive media, leading to material performance deterioration. This can not only cause equipment failure but also lead to environmental pollution and food safety issues. Utility Model Content

[0004] To solve the above-mentioned technical problems, a plastic granule with good compressive strength and corrosion resistance is provided. This technical solution solves the problems of easy breakage and easy corrosion by marine and other environments mentioned in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A plastic granule with good compressive strength and corrosion resistance includes: an outer protective shell and a reinforcing ring. The reinforcing ring is fixedly installed inside the outer surface of the outer protective shell. The outer protective shell is located on the outermost side of the plastic granule and is in direct contact with the external environment. The reinforcing ring is fixedly installed inside the outer surface of the outer protective shell. The two work together to initially build the protective and support structure of the plastic granule. The reinforcing ring has a compressive annular rib installed inside. The compressive annular rib transmits the pressure evenly to other internal components through its own annular structure, effectively improving the overall compressive strength of the plastic granule and ensuring the stability of the structure when subjected to large pressure.

[0007] Preferably, a central support column is fixedly installed at the middle of the inner side of the compression-resistant annular rib, and the central support column serves as the core support component of the entire plastic granule structure, providing stable support force for the entire structure along the axial direction. A first oblique compression rib is fixedly installed at the top of the inner side of the compression-resistant annular rib, and a second oblique compression rib is fixedly installed at the bottom of the inner side of the compression-resistant annular rib. The first oblique compression rib provides a key connection and support point to ensure that the internal structure remains stable under stress and does not undergo displacement or deformation. The central support column is inserted into the outer surface of the first oblique compression rib.

[0008] Preferably, several sets of reinforcing connectors are fixedly installed on the opposite side of the outer surface of the two sets of first inclined compressive ribs. The reinforcing connectors further enhance the connection strength between the first inclined compressive ribs, making the entire internal support structure more stable and the collaborative working ability between the components stronger. The outer surface of the compressive annular rib is provided with a buffer filler, which can play a buffering role, absorb part of the impact force, and reduce the direct impact of external forces on the internal precision components.

[0009] Preferably, the outermost surface of the outer protective shell is configured as a wear-resistant and corrosion-resistant outer layer, an anti-oxidation barrier layer is fixedly installed on the inner side of the outer surface of the wear-resistant and corrosion-resistant outer layer, and a reinforced and pressure-resistant fiber layer is provided on the inner side of the anti-oxidation barrier layer.

[0010] Preferably, a heat-insulating buffer layer is provided on the inner side of the outer surface of the reinforced compression-resistant fiber layer, a high-efficiency anti-corrosion additive layer is fixedly installed at the bottom end of the outer surface of the heat-insulating buffer layer, and an elastic reinforcing layer is fixedly installed at the rear end of the outer surface of the high-efficiency anti-corrosion additive layer.

[0011] Preferably, a sealing and adhesive layer is provided at the rear end of the outer surface of the elastic reinforcing layer, a flame-retardant auxiliary layer is fixedly installed at the bottom inner end of the sealing and adhesive layer, an antistatic functional layer is provided on the inner side of the outer surface of the flame-retardant auxiliary layer, and an inner protective base layer is provided at the bottom end of the outer surface of the antistatic functional layer located at the innermost side of the outer protective shell.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This solution proposes a plastic granule with excellent pressure resistance and corrosion resistance. Through the combination of an outer protective shell and reinforcing rings, the overall structural strength is significantly improved, greatly enhancing its pressure resistance and effectively preventing deformation and cracking. The internal pressure-resistant ring ribs, central support column, and diagonal pressure-resistant ribs form a stable support system that efficiently disperses pressure, greatly improving stability under high-pressure environments. For corrosion resistance, multi-layered protection includes an outer wear-resistant and corrosion-resistant layer, an anti-oxidation barrier layer, and a high-efficiency anti-corrosion additive layer, providing layer-by-layer protection against various corrosive media. Compared to the single protection of conventional plastic granules, this significantly extends the service life in corrosive environments.

[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0020] Reference Figure 1-3As shown, a plastic granule with good compressive strength and corrosion resistance includes: an outer protective shell 1 and a reinforcing ring 2. The outer protective shell 1 is located on the outermost side of the plastic granule and directly bears external physical impact, friction, and chemical corrosion, providing basic protection for internal components. The reinforcing ring 2 is fixedly installed inside the outer surface of the outer protective shell 1. The two fit together tightly, greatly enhancing the overall structural strength of the plastic granule. The reinforcing ring 2, like a skeleton, improves the compressive strength of the outer protective shell 1, making the plastic granule less prone to deformation or breakage when facing external forces. It initially establishes a solid protective and support structure to ensure the safety of internal components. The reinforcing ring 2 is fixedly installed inside the outer surface of the outer protective shell 1, and the reinforcing ring 2 has a compressive annular rib 3 installed inside it. Its main function is to evenly distribute the pressure. The pressure-resistant annular rib 3 disperses external pressure. When the plastic granule is under pressure, the pressure-resistant annular rib 3 transmits the pressure to other internal components through its own annular structure, avoiding excessive local pressure. This significantly improves the overall compressive strength of the plastic granule, ensuring that the structure remains stable and will not be damaged under pressure, thus providing a guarantee for the use of plastic granules in high-pressure environments. A central support column 4 is fixedly installed in the middle of the internal center of the compressive rib 3. It is firmly installed in the middle of the internal center of the compressive rib 3 and provides stable support for the entire plastic granule structure along the axial direction. It is the main beam of the plastic granule, which not only greatly enhances the compressive strength of the plastic granule in the vertical direction, but also provides a key connection point for peripheral components such as the first diagonal compressive rib 5. Under stress, the central support column 4 can ensure the internal structure. The structure is stable, preventing component displacement or deformation, maintaining the shape and performance stability of the plastic granules, and ensuring excellent performance of the plastic granules under vertical pressure. A first oblique pressure-resistant rib 5 is fixedly installed inside the pressure-resistant annular rib 3, and a second oblique pressure-resistant rib 6 is fixedly installed at the bottom of the inner part of the pressure-resistant annular rib 3. The first and second oblique pressure-resistant ribs 5 and their outer surfaces are interlocked with the central support column 4, forming a stable triangular support structure together with the pressure-resistant annular rib 3. According to the principle of triangle stability, the oblique pressure-resistant rib 5 can effectively decompose and transfer the pressure it bears, avoiding local pressure concentration. Several sets of reinforcing connectors 7 are fixed on opposite sides of the first and second oblique pressure-resistant ribs 6, further enhancing the connection between the first and second oblique pressure-resistant ribs 5 and 6. This increased strength makes the entire internal support structure more stable, enhances the collaborative working ability of each component, and allows the plastic granules to withstand more complex and high-intensity external forces, significantly improving compressive strength. Furthermore, central support columns 4 are inserted into the outer surfaces of the first and second oblique compressive ribs 5 and 6. Several sets of reinforcing connectors 7 are fixedly installed on the opposite sides of the outer surfaces of the first and second oblique compressive ribs 5 and 6. A buffer filler 8 is provided inside the outer surface of the compressive annular rib 3, filling the space between the compressive annular rib 3 and other outer structures. When the plastic granules are impacted by external forces, the buffer filler 8 can act as a buffer, absorbing part of the impact force and reducing the direct impact of external forces on the internal precision components, protecting the internal components from damage. Simultaneously, it fills the structural gaps.This enhances the overall density of the plastic granules, helping to improve their compressive strength. Furthermore, the buffer filler 8 can, to some extent, resist the intrusion of external corrosive substances, providing additional protection for internal components and extending the service life of the plastic granules.

[0021] Furthermore, the outermost surface of the outer protective shell 1 is configured as a wear-resistant and corrosion-resistant outer layer 101. Located on the outermost surface of the outer protective shell 1, it directly contacts the outside environment. With its wear-resistant and corrosion-resistant properties, it becomes the first line of defense against external friction and corrosive media. In daily use, it effectively resists wear and reduces material loss due to friction. In corrosive environments, it prevents chemical corrosion, greatly extending the service life of the plastic granules and improving their wear-resistant and corrosion-resistant properties, enabling them to adapt to various harsh environments. An anti-oxidation barrier layer 102 is fixedly installed on the inner side of the outer surface of the wear-resistant and corrosion-resistant outer layer 101. It effectively prevents external oxidizing substances from penetrating inward, preventing internal materials from deteriorating due to oxidation. Many materials experience aging and brittleness after contact with oxidizing substances. The presence of the anti-oxidation barrier layer 102 acts like a protective barrier. The internal materials are "protected" to maintain their stability and preserve the various properties of the plastic granules, indirectly improving their durability and reliability. A reinforced compression-resistant fiber layer 103 is provided on the inner side of the anti-oxidation barrier layer 102. This layer utilizes high-strength fibers to further enhance the overall compression strength of the plastic granules. The high-strength fibers distributed within it act like "steel bars" inside the plastic granules. When subjected to pressure, the fibers can share the pressure, enhancing the structural toughness and making the plastic granules perform better in terms of compression resistance. This improves the safety of the plastic granules in high-pressure environments. A heat-insulating buffer layer 104 is provided on the inner side of the outer surface of the reinforced compression-resistant fiber layer 103. Its main function is to reduce the impact of external temperature changes and impacts on the interior. In environments with large temperature variations, the heat-insulating buffer layer 104 can provide insulation, preventing damage to internal components due to drastic temperature changes.When subjected to external impact, it can also function as a buffer, working in conjunction with the buffer filler 8 to provide comprehensive protection for internal components, ensuring stable operation of the plastic granules in complex environments. A high-efficiency anti-corrosion additive layer 105 is fixedly installed at the bottom of the outer surface of the heat insulation buffer layer 104. By adding special anti-corrosion additives, the corrosion resistance of the plastic granules is further enhanced. These additives can react with external corrosive substances, neutralizing or preventing their corrosion of the plastic granules, providing strong protection for the use of plastic granules in highly corrosive environments and broadening the application range of plastic granules. An elastic reinforcement layer 106 is fixedly installed at the rear end of the outer surface of the high-efficiency anti-corrosion additive layer 105, which enhances... The elasticity of the plastic granules allows them to absorb some energy through elastic deformation under pressure, aiding in compression resistance and reducing permanent deformation caused by external forces. This enables the plastic granules to maintain good shape and performance even after repeated pressure tests, extending their service life and improving efficiency. A sealing and adhesive layer 107 is provided at the rear end of the outer surface of the elastic reinforcing layer 106. This layer tightly bonds the layers together, preventing corrosive substances from seeping into the interlayer gaps. If corrosive substances do enter the interlayer gaps, they may corrode the plastic granules from the inside. The sealing and adhesive layer 107 effectively prevents this, enhancing the overall protective performance of the plastic granules, ensuring the coordinated work of each functional layer, and improving the overall performance of the plastic granules. The sealing and bonding layer 107 features corrosion resistance and pressure resistance. A flame-retardant auxiliary layer 108 is fixedly installed at the bottom of the inner part of the layer. In specific environments, such as locations with potential fire risks, the flame-retardant auxiliary layer 108 helps improve the flame-retardant performance of the plastic granules. When exposed to a fire source, its flame-retardant properties prevent the spread of fire and reduce the risk of fire, thus increasing safety for the use of plastic granules in special environments. An antistatic functional layer 109 is provided on the inner side of the outer surface of the flame-retardant auxiliary layer 108. This layer prevents the plastic granules from generating static electricity, avoiding the adverse effects of static electricity, such as dust attraction and spark generation. This is particularly beneficial in fields sensitive to static electricity, such as electronic equipment manufacturing and chemical processing. The presence of the antistatic functional layer 109 ensures the normal use of the plastic granules, improving their applicability and safety in these fields. The bottom of the outer surface of the antistatic functional layer 109 is located at the innermost side of the outer protective shell 1, where an inner protective base layer 110 is situated. This inner protective base layer 110 provides basic protective support for the entire multi-layer structure, working in conjunction with other layers. It not only enhances the stability of the entire structure but also, to a certain extent, resists internal stress and minor damage, ensuring that each functional layer effectively functions and collectively achieves the plastic granules' compressive strength, corrosion resistance, and other functions. It is a crucial guarantee for the overall performance of the plastic granules.

[0022] Working principle and implementation method: When the plastic granule is subjected to external pressure, the outer protective shell 1 and the reinforcing ring 2 work together to resist it. The reinforcing ring 2 enhances the strength of the outer protective shell 1 to initially resist the pressure. The pressure is transmitted to the pressure-resistant annular rib 3, whose annular structure evenly distributes the pressure to the internal components. At the same time, the central support column 4 provides stable support along the axial direction to strengthen vertical pressure resistance. The first oblique pressure-resistant rib 5 and the second oblique pressure-resistant rib 6, together with the central support column 4 and the pressure-resistant annular rib 3, form a triangular support structure. Based on the principle of triangular stability, the pressure is effectively decomposed to avoid local concentration. The reinforcing connector 7 further stabilizes the connection between the oblique pressure-resistant ribs and improves the overall pressure resistance. In terms of corrosion resistance, the wear-resistant and corrosion-resistant outer layer 101 directly resists external friction and corrosive media. The anti-oxidation barrier layer 102 prevents oxidizing substances from penetrating. The high-efficiency anti-corrosion additive layer 105 reacts with corrosive substances. The sealing and bonding layer 107 prevents substances from entering from the gaps between the layers, thus ensuring corrosion resistance in all aspects.
