[0026] In the following description, numerous specific details are set forth to provide a more thorough understanding of this application. However, it will be apparent to those skilled in the art that embodiments of this application may be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described to avoid confusion with embodiments of this application.
[0027] The preferred embodiments of this application will now be described with reference to the accompanying drawings. It should be noted that the terms "upper," "lower," and similar expressions used herein are for illustrative purposes only and are not intended to be limiting.
[0028] In this document, ordinal numbers such as “first” and “second” used in this application are merely identifiers and do not include any other meaning, such as a specific order.
[0029] To fully understand the embodiments of this application, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this application is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this application are described in detail below; however, in addition to these detailed descriptions, this application may also include other embodiments.
[0030] This application provides a container. The inner surface of the container is provided with a protective structure, thereby increasing the corrosion resistance and wear resistance of the inner surface of the container.
[0031] Please refer to Figures 1 to 4The container includes a body 110 and a door 115. The body 110 includes a base frame 113, end walls 111, side walls 112, and a top wall 114. The base frame 113, end walls 111, side walls 112, and top wall 114 form a generally rectangular parallelepiped structure. The body 110 has an opening. The door 115 is movably connected to the body 110 for opening or closing the opening.
[0032] At least one of the base frame 113, end wall 111, side wall 112, top wall 114, and door 115 constitutes the base 116 of the housing 110. Figure 3 and Figure 4 As shown, the inner surface of the substrate 116 is made of metal. The base frame 113 includes a steel floor. A protective structure is disposed on the inner surface (upper surface) of the steel floor. The protective structure includes a primer coating 120. The primer coating 120 can be formed by adhering paint to the inner surface of the substrate 116. The inner surface of the substrate 116 is the surface of the substrate 116 near the center (inside the box) of the housing 110. The primer coating 120 is laid on the inner surface of the substrate 116. The primer coating 120 covers the inner surface of the substrate 116. In this way, the primer coating 120 can seal the metal surface and prevent secondary rusting.
[0033] like Figure 3 and Figure 4 As shown, the protective structure also includes a reinforcing layer 130. The reinforcing layer 130 comprises resin and reinforcing fibers. The reinforcing layer 130 can be attached to the inner surface of the base coating 120. The inner surface of the base coating 120 is the surface of the base coating 120 near the center of the housing 110. The reinforcing layer 130 is laid on the inner surface of the base coating 120. The reinforcing layer 130 covers the inner surface of the base coating 120. Thus, the reinforcing fibers can increase the mechanical strength, deformation resistance, and crack resistance of the protective structure. The resin can increase the corrosion resistance of the protective structure.
[0034] like Figure 3 and Figure 4 As shown, the protective structure also includes an inner surface layer 140. The inner surface layer 140 is laid on the inner surface of the reinforcing layer 130. The inner surface layer 140 covers the inner surface of the reinforcing layer 130. The inner surface layer 140 includes resin and wear-resistant filler. Thus, the wear-resistant filler can increase the wear resistance of the protective structure. The resin in the inner surface layer 140 can increase the corrosion resistance of the protective structure.
[0035] In this embodiment, the inner surface of the substrate 116 is provided with a base coating 120, a reinforcing layer 130, and an inner surface layer 140 sequentially from the outside to the inside (from the outside of the container towards the inside of the container). The paint in the base coating 120 can seal the metal surface and prevent secondary rusting. The reinforcing fibers in the reinforcing layer 130 can increase the mechanical strength, deformation resistance, and crack resistance of the protective structure. The resin in the reinforcing layer 130 can increase the corrosion resistance of the protective structure. The wear-resistant filler in the inner surface layer 140 can increase the wear resistance of the protective structure. The resin in the inner surface layer 140 can increase the corrosion resistance of the protective structure. In this way, the container has strong corrosion resistance and high wear resistance, and can be used to transport and load sulfur, fertilizer, coke, sand, gravel, and mineral bulk cargo.
[0036] Optionally, the base coating 120 includes a silane coupling agent. Therefore, the base coating 120 can enhance the adhesion strength of the reinforcing layer 130 to the base coating 120. Optionally, such as Figure 4 As shown, the reinforcing layer 130 includes a structural reinforcing layer 131. The structural reinforcing layer 131 is attached to the inner surface of the base coat 120. The structural reinforcing layer 131 is laid on the inner surface of the base coat 120. The structural reinforcing layer 131 covers the inner surface of the base coat 120. The structural reinforcing layer 131 includes resin and a first reinforcing fiber article. The first reinforcing fiber article includes chopped strand mat and / or woven fabric. Both the chopped strand mat and the woven fabric include reinforcing fibers, thereby increasing the mechanical strength, deformation resistance, and crack resistance of the protective structure. The resin can increase the corrosion resistance of the protective structure.
[0037] Furthermore, the structural reinforcement layer 131 includes at least two layers (e.g., 2 to 4 layers) of first reinforcing fiber articles. One of two adjacent layers of first reinforcing fiber articles is either chopped strand mat or woven fabric, and the other layer is either chopped strand mat or woven fabric. For example, the at least two layers of first reinforcing fiber articles are alternating layers of chopped strand mat and woven fabric. Thus, a layer of woven fabric is disposed between two adjacent layers of chopped strand mat. A layer of chopped strand mat is disposed between two adjacent layers of woven fabric. A layer of resin is disposed between two adjacent layers of first reinforcing fiber articles. This further increases the mechanical strength, deformation resistance, and crack resistance of the protective structure.
[0038] Optionally, such as Figure 4As shown, the reinforcing layer 130 also includes a transition layer 132. The transition layer 132 is attached to the inner surface of the structural reinforcing layer 131. The inner surface of the structural reinforcing layer 131 is the inner surface of the structural reinforcing layer 131 near the center of the housing 110. The transition layer 132 is laid on the inner surface of the structural reinforcing layer 131. The transition layer 132 covers the inner surface of the structural reinforcing layer 131. The transition layer 132 includes resin and a second reinforcing fiber product. The second reinforcing fiber product includes a surface felt. The surface felt includes reinforcing fibers, thereby increasing the mechanical strength, deformation resistance, and crack resistance of the protective structure. The resin can increase the corrosion resistance of the transition layer 132.
[0039] Optionally, the resin content of the transition layer 132 is >90%. Specifically, the ratio of the weight of the resin in the transition layer 132 to the weight of the transition layer 132 is >90%. As a result, the transition layer 132 forms a dense and corrosion-resistant barrier, further increasing the corrosion resistance of the transition layer 132.
[0040] Optionally, the thickness of the transition layer 132 is 1.5 mm to 3 mm. This further increases the corrosion resistance of the transition layer 132.
[0041] Optionally, the wear-resistant filler includes at least one of silicon carbide, alumina, and quartz sand. This results in a wear-resistant layer with strong wear resistance.
[0042] Optionally, the particle size of the wear-resistant filler is 80 mesh to 400 mesh. As a result, the wear-resistant layer has strong wear resistance.
[0043] Optionally, in the inner surface layer 140, the weight ratio of the wear-resistant filler to the resin ranges from 30% to 60%. This results in a wear-resistant layer with strong wear resistance.
[0044] Optionally, the resin used for the reinforcing layer 130 and the inner surface layer 140 includes one of polyester resin, epoxy resin, vinyl ester resin, and furan resin. This facilitates the selection of resin.
[0045] Optionally, the reinforcing fiber includes one of glass fiber, carbon fiber, aramid fiber, ultra-high molecular weight polyethylene fiber, and basalt fiber. This facilitates the selection of the reinforcing fiber.
[0046] This application also provides a method for processing a container. The method for processing a container is used to process the aforementioned container.
[0047] The container processing method includes steps S1, S3, S5, S7 and S9.
[0048] Step S1: Clean the inner surface of the container base 116 to remove scale, rust, oil and old coatings from the inner surface of the base 116.
[0049] The inner surface of the substrate 116 is treated (e.g., by sandblasting) to thoroughly remove oxide scale, rust, oil, and old coatings from the inner surface of the metal substrate 116, forming a rough, clean inner surface. Step S3 is then performed after step S1.
[0050] Step S3: Apply a base coating 120 to the inner surface of the substrate 116.
[0051] After cleaning the inner surface of the substrate 116, paint is evenly applied to the inner surface of the substrate 116 to form a base coat 120. Step S5 is then performed after step S3.
[0052] In this article, the structure formed by uniform brushing can also be formed by uniform spraying with a spray gun.
[0053] Step S5: A reinforcing layer 130 is provided on the inner surface of the base coating 120.
[0054] During the process of setting the reinforcing layer 130, pressure rollers are used to repeatedly roll and compact the reinforcing layer 130 to remove air bubbles as much as possible and compact the reinforcing fibers of the reinforcing layer 130, so that the resin in the reinforcing layer 130 completely impregnates the reinforcing fiber products (the first reinforcing fiber product and the second reinforcing fiber product). Step S7 is performed after step S5.
[0055] Step S7: An inner surface layer 140 is provided on the inner surface of the reinforcing layer 130.
[0056] The prepared resin mixed with wear-resistant filler is evenly applied to the inner surface of the reinforcing layer 130. Step S9 is performed after step S7.
[0057] Step S9: Curing the container in an environment where the temperature and humidity are within a preset range.
[0058] The treated container is left to stand in an environment where the temperature and humidity are within a preset range, thereby solidifying the reinforced structure.
[0059] In this embodiment, the container processing method is used to process the aforementioned container. The inner surface of the substrate 116 is sequentially provided with a base coating 120, a reinforcing layer 130, and an inner surface layer 140 from the outside to the inside (from the outside of the container towards the inside of the container). The paint of the base coating 120 can seal the metal surface and prevent secondary rusting. The reinforcing fibers of the reinforcing layer 130 can increase the mechanical strength, deformation resistance, and crack resistance of the protective structure. The resin of the reinforcing layer 130 can increase the corrosion resistance of the protective structure. The wear-resistant filler of the inner surface layer 140 can increase the wear resistance of the protective structure. The resin of the inner surface layer 140 can increase the corrosion resistance of the protective structure. In this way, the container has strong anti-corrosion performance and high wear resistance.
[0060] Optionally, the roughness grade of the inner surface of the cleaned substrate 116 is Sa 2.5. This increases the mechanical interlocking area between the inner surfaces of the primer 120 and the substrate 116, thereby increasing the adhesion between the primer 120 and the inner surfaces of the substrate 116.
[0061] Optionally, step S3 is executed after a preset time has elapsed since step S1. The preset time is less than 4 hours. As a result, the amount of dust and other debris adhering to the inner surface of the substrate 116 can be reduced when step S3 is executed, thereby increasing the adhesion between the base coating 120 and the inner surface of the substrate 116.
[0062] Optionally, the thickness of the base coating 120 is between 80 μm and 120 μm. For example, the thickness of the base coating 120 is one of 85 μm, 90 μm, 95 μm, 100 μm, 105 μm, and 110 μm. Thus, the base coating 120 can adhere more firmly to the inner surface of the substrate 116.
[0063] Optionally, step S5 includes step S51. Step S51: sequentially lay one of a first reinforcing fiber product and a layer of resin, then lay the other, and then repeatedly roll it a first preset number of times.
[0064] Following step S3, step S51 is executed. After laying a layer of the first reinforcing fiber product and uniformly applying a layer of resin, a pressure roller is used to repeatedly roll the product a first preset number of times to remove air bubbles as much as possible, compact the reinforcing fibers, and ensure that the resin completely impregnates the first reinforcing fiber product, thereby forming a structure in which the first reinforcing fiber product is impregnated with resin, thus constituting the structural reinforcement layer 131. The first preset number of times can be set as needed. In step S51, a layer of the first reinforcing fiber product can be laid first, followed by a layer of resin. Alternatively, a layer of resin can be applied first, followed by a layer of the first reinforcing fiber product.
[0065] Step S5 also includes step S52. Step S52: sequentially lay one of a second reinforcing fiber product and a layer of resin, and then lay the other.
[0066] Step S52 is executed after step S51. After laying a layer of the second reinforcing fiber and uniformly applying a layer of resin, a pressure roller is used to repeatedly roll the product a second preset number of times to remove air bubbles as much as possible, compact the reinforcing fibers, and allow the resin to more completely impregnate the second reinforcing fiber product, thereby forming a structure in which the second reinforcing fiber product is impregnated with resin, and thus forming the transition layer 132. The second preset number of times can be set as needed, and the second preset number of times can be the same as the first preset number of times, or they can be different. In step S52, a layer of the second reinforcing fiber product can be laid first, and then a layer of resin can be applied. Alternatively, a layer of resin can be applied first, and then a layer of the second reinforcing fiber product can be laid.
[0067] For example, a layer of resin can be applied first, then a layer of second reinforcing fiber product can be laid, then another layer of resin can be applied, and so on, until the number of layers of the second reinforcing fiber product in the transition layer 132 reaches the required number.
[0068] Optionally, if the resin in the last layer of step S52 has not cured, step S7 is performed, or After the second reinforcing fiber product of the last layer in step S52 is laid, proceed to step S7.
[0069] If the inner surface of the transition layer 132 (the last layer in step S52) is resin, then step S7 is executed while the resin in the last layer of step S52 is not yet cured.
[0070] If the inner surface of the transition layer 132 (the last layer in step S52) is a second reinforcing fiber product, then after the last layer of the second reinforcing fiber product is laid, step S7 is executed directly.
[0071] Optionally, the preset temperature range is 15℃ to 30℃. The preset humidity is less than 80%. This enhances the curing effect of the protective structure, resulting in stronger corrosion resistance and wear resistance after curing.
