Description

Technical Field

[0001] This invention relates to the field of metal surface treatment technology, and more specifically to a surface treatment process for stainless steel panel steel formwork suitable for bridge engineering. Background Technology

[0002] With the increasing demand for aesthetically pleasing and long-term corrosion-resistant bridge engineering, stainless steel panels are widely used in bridge construction, landscape decoration structures, and pedestrian walkway load-bearing structures. During processing and on-site installation, stainless steel panels require welding for splicing and fixing. After welding, defects such as weld points, welding spatter, and weld scratches are inevitable on the panel surface. Furthermore, mechanical scratches can occur during transportation and installation, severely affecting the panel's appearance and corrosion resistance. Therefore, professional surface treatment is essential for the steel formwork used to install the welded stainless steel panels.

[0003] In existing technologies, the surface treatment of stainless steel sheets mostly employs large-scale automated polishing and wire drawing equipment. This type of equipment can only process regular flat sheets and cannot meet the surface treatment needs of irregularly shaped or irregularly shaped steel templates. Existing manual surface treatment processes lack standardized process design and parameter matching, commonly suffering from unreasonable polishing grit matching and non-standard process connections. This easily leads to residual surface scratches, insufficient flatness, and defects such as texture breakage, skipped lines, and obvious seams after subsequent wire drawing. Furthermore, uneven force application during manual polishing can cause localized high temperatures from friction, leading to oxidation and discoloration of the stainless steel surface, resulting in color differences. This not only disrupts the uniformity of appearance but also reduces the integrity of the passivation film on the stainless steel surface, affecting the long-term corrosion resistance of the panel. In addition, existing manual wire drawing processes lack suitable auxiliary media. The high frictional resistance between the wire drawing wheel and the stainless steel surface during the wire drawing process easily leads to uneven texture and surface scratches, failing to meet the high standards of appearance consistency and long-term durability required for stainless steel structures in bridge engineering.

[0004] Therefore, developing a surface treatment process for stainless steel panel formwork that is compatible with irregularly shaped structures, enables on-site in-situ construction, standardizes procedures, and ensures stable and controllable surface treatment quality has become an urgent technical problem to be solved in this field. Summary of the Invention

[0005] Therefore, to address the aforementioned shortcomings, this invention provides a surface treatment process for stainless steel panel formwork. This process solves the problems of existing technologies, such as inability to adapt to irregularly shaped stainless steel panel formwork structures, high on-site construction difficulty, unstable surface treatment quality, and susceptibility to color differences, scratches, and uneven brushed texture.

[0006] This invention is implemented by constructing a surface treatment process for stainless steel panel templates, characterized by comprising a preliminary polishing process, a fine polishing process, a high-precision polishing process, and a wire drawing process performed sequentially. The specific steps are as follows: S1 Initial Polishing Process: Using a 100-grit polishing pad and a handheld polishing machine, the weld points, scratches, and welding spatter defects on the surface of the stainless steel panel template are initially polished to remove obvious defects on the panel surface. S2 Fine Polishing Process: Using a 200-grit polishing pad and a handheld polishing machine, the panel surface after the initial polishing process is polished to eliminate the polishing marks left by the initial polishing process, making the panel surface smooth and free of obvious scratches. S3 Fine Polishing Process: Using 320-grit polishing pads and a handheld polishing machine, the panel surface after the fine polishing process is finely polished to achieve a smooth, bright, and uniform surface. S4 Wire Drawing Process: Using 600-mesh talc powder as an auxiliary medium, a handheld wire drawing machine is used to draw the surface of the stainless steel panel template after the fine polishing process, resulting in a finished stainless steel panel template with clear and continuous wire drawing texture, smooth and flat surface, and no seam color difference or defects.

[0007] According to the stainless steel panel template surface treatment process of the present invention, the polishing process of S1 to S3 is characterized in that the force applied to the panel surface by the hand-held polishing machine is controlled to maintain uniform speed of polishing and avoid local discoloration of the panel contact area due to excessive friction and heat.

[0008] According to the surface treatment process of stainless steel panel templates of the present invention, the polishing direction of the polishing pad in the polishing process S1 to S3 is consistent with the wire drawing texture direction in the wire drawing process S4.

[0009] The surface treatment process for stainless steel panel templates according to the present invention is characterized in that the handheld polishing machine is a Dongcheng S1M-FF09-100S model angle grinder.

[0010] The surface treatment process for stainless steel panel templates according to the present invention is characterized in that the handheld wire drawing machine is a Dongcheng S1M-FF-120×100 model wire drawing machine.

[0011] According to the surface treatment process of stainless steel panel templates of the present invention, the characteristic is that in the S4 wire drawing process, 600-mesh talc powder is first uniformly coated on the surface of the panel to be wire drawn, and then the wire drawing process is completed by a hand-held wire drawing machine moving the blade at a uniform speed along a preset uniform texture direction.

[0012] The present invention has the following advantages: First, this invention uses handheld equipment with a standardized step-by-step polishing and wire drawing process, which can perfectly adapt to the irregular cross-sectional structure of stainless steel panel steel templates. At the same time, it can realize in-situ surface treatment after bridge installation, solving the pain points of large automated equipment being unable to handle irregular structures and unable to carry out on-site construction, and has strong construction flexibility.

[0013] Secondly, this invention uses a step-by-step polishing process with gradient grits of 100 grit for initial polishing, 200 grit for fine polishing, and 320 grit for precision polishing to remove surface defects and grinding marks step by step, achieving precise control of surface flatness. This lays a uniform foundation for subsequent wire drawing processing and avoids defects such as broken wire drawing texture, skipped lines, and obvious seams from the root, ensuring the consistency of the board surface effect.

[0014] Third, the present invention uses 600-mesh talc powder as an auxiliary medium in the wire drawing process, which can effectively reduce the frictional resistance between the wire drawing wheel and the stainless steel plate surface, and at the same time play a role in lubrication and cooling, avoiding the problems of scratches on the plate surface and local overheating and discoloration during the wire drawing process, and further improving the clarity and continuity of the wire drawing texture and the color difference control effect of the plate surface.

[0015] Fourth, this invention achieves standardized construction of stainless steel panel steel formwork surface treatment through standardized process parameters, equipment selection and operation control requirements, reduces quality fluctuations in manual operation, ensures the stability of finished product surface quality, and improves construction efficiency, which can meet the large-scale construction needs of bridge engineering.

[0016] Fifth, the stainless steel panel template treated by this invention has a complete and uniform passivation film on the surface, without local oxidation defects. While ensuring the aesthetic effect, it greatly improves the long-term anti-corrosion performance of the panel and extends the service life of the stainless steel bridge structure. Attached Figure Description

[0017] Figure 1 This is a schematic diagram illustrating the surface treatment effect of stainless steel panel steel template. Detailed Implementation

[0018] The following will be combined with the appendix Figure 1 This invention will be described in detail, and the technical solutions in the embodiments of this invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0019] This invention provides an improved surface treatment process for stainless steel T-beam panels, which will be further described in detail below with reference to specific embodiments.

[0020] Example 1: This example discloses a surface treatment process for stainless steel panel formwork. It addresses the issue of weld points, welding spatter, and installation scratches on the surface of the stainless steel panel formwork after welding. The specific treatment process is as follows: Preparations before construction: Prepare a Dongcheng S1M-FF09-100S handheld polisher with 100-mesh, 200-mesh, and 320-mesh polishing pads; prepare a Dongcheng S1M-FF-120×100 handheld wire drawing machine with nylon wire drawing wheels; prepare 600-mesh talc powder.

[0021] Initial polishing process: Using a 100-grit polishing pad mounted on a handheld polishing machine, the weld points, welding spatter, and obvious scratches on the stainless steel panel template are initially polished. The polishing direction is consistent with the subsequent pre-set wire drawing direction. The polishing machine is moved at a uniform speed to remove all obvious surface defects, so that the panel surface is free of raised weld beads and spatter.

[0022] Fine polishing process: Replace with a 200-grit polishing pad and perform a full polishing of the entire panel surface after the initial polishing to eliminate the rough polishing marks left by the initial polishing. During the polishing process, control the force to be applied evenly and avoid excessive force in some areas. After polishing, the panel surface is smooth and there are no obvious scratches visible to the naked eye.

[0023] Fine polishing process: Replace with 320-grit polishing pads to finely polish the panel surface after fine polishing, fully covering the surface of the stainless steel panel template. After polishing, the panel surface is flat, bright, and uniform, without any residual micro-scratches, providing a uniform base surface for wire drawing.

[0024] Wire drawing process: 600-mesh talcum powder is evenly coated on the polished panel surface. A handheld wire drawing machine is used to draw the wire at a uniform speed along the preset uniform longitudinal texture direction. During the wire drawing process, the speed is kept consistent, with no overlapping or missed areas. The talcum powder plays a role in reducing resistance, lubrication, and cooling throughout the process. The final product is a stainless steel panel template with clear and continuous wire drawing texture, smooth and flat surface, no seams, no color difference, and no defects.

[0025] Finished product inspection: The surface of the treated panel is visually inspected. The texture consistency meets the standard, there are no defects such as discoloration, scratches, or color difference, and the surface roughness meets the design requirements.

[0026] Example 2 The difference between this embodiment and Embodiment 1 is that this embodiment performs in-situ surface treatment on the stainless steel panel template that has been installed on-site. The stainless steel panel template has weld points and installation scratches from on-site welding. In the processing flow, the polishing process adjusts the holding angle of the polishing machine for irregular corners and narrow gaps to ensure that all areas are polished properly. In the wire drawing process, the corner wheel of the wire drawing machine is used to process the corner areas to ensure that the texture at the corners is continuous and consistent with the flat area, without any seam marks. The force applied by the polishing machine is controlled throughout the process to avoid overheating due to friction, which could cause local discoloration of the panel. The final product quality is consistent with that of Embodiment 1.

[0027] This invention addresses the challenges of surface treatment for stainless steel panels and formwork in bridge engineering, and possesses strong engineering applicability and practical value throughout the entire lifecycle.

[0028] In terms of scenario adaptability, this process uses handheld equipment in conjunction with standardized procedures, which is perfectly adapted to the irregular cross-sectional structure of stainless steel panel steel formwork. It can take into account both the batch processing of prefabricated parts in the factory and the on-site construction after bridge installation. It solves the industry pain point that large automated equipment cannot handle irregular structures and cannot operate on-site, and greatly expands the applicable scenarios.

[0029] In terms of quality control, the flatness of the panel is precisely controlled by the step-by-step polishing process with gradient mesh size. Combined with the talcum powder-assisted wire drawing process, the defects such as scratch residue, texture breakage, and local discoloration that are prone to occur in manual processing are solved from the root. The finished product has a strong consistency in appearance, while the passivation film on the stainless steel surface is completely preserved, which greatly improves the long-term anti-corrosion performance of the panel and meets the dual high standards of aesthetics and durability required by bridge engineering.

[0030] In terms of economic efficiency, this process requires no investment in large equipment, has low equipment and material costs, and standardized procedures lower the operational threshold, enabling assembly line operations, significantly improving construction efficiency and reducing rework rates. At the same time, the treated panels can significantly reduce subsequent maintenance and replacement costs, resulting in significant economic benefits throughout the entire life cycle. It is well-suited to the large-scale construction needs of bridge engineering and has outstanding value for industry promotion.

[0031] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
