[0002] With the rapid development of the modern construction industry, the requirements for building materials are increasing, especially in terms of strength, durability, aesthetics and environmental protection. As a high-quality building decoration material, high-strength aluminum veneer has been widely used in curtain walls, ceilings, interior decoration and other fields due to its light weight, high strength, corrosion resistance, easy processing, and beautiful appearance. However, the traditional high-strength aluminum veneer production process has gradually revealed some technical problems in the face of diversified market demand, higher product quality requirements and increased environmental pressure. The adjustment often relies on manual experience and simple testing equipment, resulting in inaccurate control of alloy element content, which in turn affects the mechanical properties and corrosion resistance of the product. This has become a technical bottleneck for improving product performance and durability. Secondly, traditional processes mostly use manual or semi-automatic methods for surface treatment, which not only has low production efficiency, but also makes it difficult to ensure uniformity of coating quality, affecting the overall aesthetics and service life of the product. At the same time, the high labor cost in the production process also increases the operating burden of enterprises. Finally, with the enhancement of environmental awareness and the tightening of laws and regulations, traditional processes are facing increasing pressure in material selection, energy consumption and waste disposal. How to achieve green production, energy conservation and emission reduction while ensuring product quality and performance has become a technical problem that needs to be solved urgently.

Surface treatment: The aluminum veneer after extrusion molding is subjected to surface treatment, including but not limited to anodizing to increase surface hardness and corrosion resistance, electrophoretic coating to form a uniform and dense anti-corrosion coating, or fluorocarbon spraying to provide excellent weather resistance and decorative effects. During the surface treatment process, various process parameters must be strictly monitored to ensure the uniformity of the coating, excellent adhesion and long-term stability, and to avoid coating shedding or damage.

[0006] Preferably, the raw material selection and pretreatment step also includes chemical etching of the aluminum alloy raw material to further increase the surface roughness and improve the adhesion of the coating or reinforcement layer in the subsequent processing steps.

[0011] Preferably, the anodizing treatment in the surface treatment step adopts micro-arc oxidation technology to form a denser and harder oxide film layer on the surface of the aluminum veneer, further improving its wear resistance and corrosion resistance.

[0012] Preferably, the production process of the high-strength aluminum veneer is characterized in that the electrophoretic coating or fluorocarbon spraying process in the surface treatment step adopts automated spraying equipment and an intelligent control system to ensure the uniformity and consistency of the coating thickness while reducing coating waste and environmental pollution.

[0020] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0021] Example

[0022] like Figure 1 As shown, a high-strength aluminum veneer production process proposed in one embodiment of the present invention includes the following steps: raw material selection and pretreatment: select an aluminum alloy with high strength and high corrosion resistance as the raw material, then thoroughly clean the raw material to remove surface dirt, degrease the raw material to ensure that there is no grease residue on the surface, and finally dry the raw material to obtain a clean, impurity-free aluminum alloy material surface, alloy composition adjustment: according to the preset product performance requirements, including but not limited to specific indicators of mechanical properties and corrosion resistance, the alloy element content in the aluminum alloy is accurately adjusted to optimize the comprehensive performance of the alloy material, heating and extrusion molding: the pretreated aluminum alloy material is heated to a suitable temperature range, which is sufficient to soften the material without excessive oxidation or deformation, and then a high-precision extruder is used to extrude the heated aluminum alloy under the condition of strictly controlling key parameters such as temperature, extrusion speed and extrusion pressure to form an aluminum veneer with a predetermined shape and size to ensure the uniformity and consistency of the plate, and internal structure reinforcement: reinforcing ribs or reinforcing layers are reasonably set inside the aluminum veneer to enhance the overall structural strength and deformation resistance of the aluminum veneer. The reinforcing ribs or reinforcing layers are firmly bonded to the aluminum veneer body by welding, riveting or high-strength bonding to ensure the strength and durability of the bonded parts. Surface treatment: The aluminum veneer after extrusion molding is subjected to surface treatment, including but not limited to anodizing to increase surface hardness and corrosion resistance, electrophoretic coating to form a uniform and dense anti-corrosion coating, or fluorocarbon spraying to provide excellent weather resistance and decorative effects. During the surface treatment process, various process parameters must be strictly monitored to ensure the uniformity of the coating, excellent adhesion and long-term stability, and to avoid coating shedding or damage.

[0023] In the present invention, the raw materials are selected from qualified suppliers to purchase aluminum alloy materials with high strength and high corrosion resistance, such as commonly used aluminum alloys of grades 6061, 7075, etc. The aluminum alloy materials are placed in a cleaning tank, and deionized water and a special cleaning agent are used to thoroughly clean the aluminum alloy materials to remove impurities such as oil stains and dust on the surface. The cleaned aluminum alloy materials are degreased by an alkaline degreasing agent to ensure that there is no grease residue on the surface. The surface of the aluminum alloy materials after degreasing is completely dried by a hot air dryer or natural air drying to prepare for subsequent processes. According to the mechanical properties and corrosion resistance requirements required by the product, the content of alloy elements in the aluminum alloy is accurately adjusted. This usually involves adding an appropriate amount of alloy elements such as copper, magnesium, and zinc, and strictly controlling their content to achieve a preset alloy formula. During the adjustment process, the alloy composition can be monitored in real time by methods such as spectral analysis or X-ray fluorescence analysis to ensure that the content of alloy elements is accurate, and the pretreated aluminum alloy material is sent to a heating furnace and heated to a suitable temperature range. The selection of heating temperature should be based on the characteristics of the alloy and the requirements of the extruder to ensure that the material has good plasticity and fluidity during the extrusion process. The heated aluminum alloy material is fed into a high-precision extruder and extruded through a die. During the extrusion process, parameters such as temperature, extrusion speed and extrusion pressure are strictly controlled to ensure that the shape, size and performance of the aluminum veneer meet the design requirements. After the extrusion is completed, the aluminum veneer is cut, trimmed and other subsequent treatments are performed to obtain a finished product of a predetermined shape and size. According to the specific application requirements and stress conditions of the aluminum veneer, a reinforcing rib or reinforcing layer is set inside the aluminum veneer to enhance its overall strength and anti-deformation ability. The reinforcing rib or reinforcing layer can be firmly combined with the aluminum veneer body by welding, riveting or bonding. During the bonding process, ensure that the bonding surface is clean and free of impurities, and use appropriate process parameters to ensure the bonding strength. The aluminum veneer after extrusion molding and internal structure strengthening is surface treated to improve its corrosion resistance, wear resistance and decorativeness. The surface treatment process can be selected according to customer needs and product design requirements. Anodizing, electrophoretic coating, fluorocarbon spraying, etc. During the surface treatment process, process parameters such as voltage, current, temperature, time, etc. are strictly controlled to ensure that the coating is uniform, has strong adhesion and is not easy to fall off.

[0024] The raw material selection and pretreatment step also includes chemical etching of the aluminum alloy raw material to further increase the surface roughness and improve the adhesion of the coating or reinforcement layer in the subsequent treatment steps.

[0025] In the present invention, in the pretreatment step, in addition to basic cleaning, degreasing and drying, a chemical etching process is also added. The aluminum alloy material is immersed in an etching solution containing a certain concentration of acid or alkali, and the roughness of the material surface is increased by chemical reaction, thereby improving the adhesion between the subsequent coating or reinforcement layer and the substrate. After etching, it is necessary to clean and dry again to ensure that there is no residual etching solution on the surface.

[0026] In the alloy composition adjustment step, the alloy elements are added by a precise metering system, and the alloy composition is monitored in real time by spectral analysis or X-ray fluorescence analysis to ensure that the alloy element content reaches a preset value.

[0027] In the present invention, when adjusting the alloy composition, a high-precision metering system is used to accurately weigh the alloy elements, and the alloy elements are added to the molten aluminum alloy through an automated control system. At the same time, online monitoring technologies such as spectral analysis or X-ray fluorescence analysis are used to monitor the changes in the alloy composition in real time to ensure that the content of the alloy elements reaches the preset value. If necessary, fine-tuning can be performed to ensure the accuracy of the alloy composition.

[0028] Among them, in the heating and extrusion molding steps, the heating process adopts a step-by-step temperature increase strategy to reduce the thermal stress inside the material, and an online cooling system is introduced during the extrusion process to control the outlet temperature of the plate to avoid performance degradation caused by overheating.

[0029] In the present invention, during the heating process, a step-by-step temperature increase strategy is adopted to gradually heat the aluminum alloy material to a suitable temperature. This strategy helps to reduce the thermal stress inside the material and avoid cracks or deformation. During extrusion molding, an online cooling system is introduced to control the outlet temperature of the plate by adjusting the flow rate and temperature of the cooling water to ensure the mechanical properties and dimensional stability of the material during the extrusion process.

[0030] Among them, in the internal structure strengthening step, the shape, layout and size of the reinforcing ribs or reinforcing layers are optimized according to the specific application requirements and stress conditions of the aluminum veneer to achieve the best reinforcement effect. The bonding interface between the reinforcing ribs or reinforcing layers and the aluminum veneer body adopts special treatment processes, such as sandblasting, chemical activation, etc., to enhance the mechanical bite force and chemical bonding force of the bonding surface and improve the stability of the overall structure.

[0031] In the present invention, the shape, layout and size of the reinforcing ribs or reinforcing layers are reasonably designed according to the specific application requirements of the aluminum veneer. During the bonding process, the bonding interface is specially treated, such as sandblasting to increase the surface roughness, or a chemical activator is used to promote the chemical reaction of the bonding surface, thereby enhancing the mechanical bite force and chemical bonding force of the bonding surface. The bonding between the reinforcing ribs or reinforcing layers and the aluminum veneer body is firm and reliable, meeting the use requirements.

[0032] Among them, the anodizing treatment in the surface treatment step adopts micro-arc oxidation technology to form a denser and harder oxide film layer on the surface of the aluminum veneer, further improving its wear resistance and corrosion resistance. The production process of the high-strength aluminum veneer is characterized in that the electrophoretic coating or fluorocarbon spraying process in the surface treatment step adopts automated spraying equipment and an intelligent control system to ensure the uniformity and consistency of the coating thickness, while reducing paint waste and environmental pollution.

[0033] In the present invention, when surface treatment is performed, an appropriate process is selected according to customer needs. If anodizing is used, micro-arc oxidation technology is used to form a dense and hard oxide film layer on the surface of the aluminum single plate under the action of a high-voltage electric field. If electrophoretic coating or fluorocarbon spraying process is used, automated spraying equipment and intelligent control systems are used to ensure that the coating thickness is uniform, the adhesion is strong and it is not easy to fall off. During the coating process, process parameters such as voltage, current, temperature, time, etc. are strictly controlled to obtain an ideal coating effect.

[0034] This also includes quality inspection and evaluation. After the surface treatment is completed, the finished aluminum panels are subjected to comprehensive quality inspection, including but not limited to appearance inspection, dimension measurement, mechanical property testing and corrosion resistance testing, to ensure that the product quality meets relevant standards and customer requirements. In the quality inspection and evaluation steps, automated testing equipment and data analysis systems are introduced to conduct real-time analysis and feedback of the test data, so as to timely adjust the production parameters, optimize the production process, and improve product qualification rate and production efficiency.

[0035] In the present invention, after the surface treatment is completed, the finished aluminum veneer is subjected to comprehensive quality inspection and evaluation. First, an appearance inspection is carried out to ensure that there are no defects such as scratches and bubbles on the surface; then, dimensional measurement and mechanical property testing are carried out to verify whether the dimensional accuracy and mechanical properties of the aluminum veneer meet the relevant standards and customer requirements; finally, a corrosion resistance test is carried out to evaluate the corrosion resistance of the aluminum veneer under different environments. Automated testing equipment and data analysis systems are introduced in the quality inspection process to perform real-time analysis and feedback on the test data. If unqualified products are found, they are marked, isolated and disposed of in a timely manner. At the same time, production parameters are adjusted and production processes are optimized according to the test results to improve product qualification rate and production efficiency.
