The fluorocarbon spraying process flow is: Pretreatment process: degreasing and decontamination of aluminum profiles →water washing→alkali washing (degreasing)→water washing→acid washing→water washing→chromization→water washing→pure water washing Spraying process: Primer spraying→topcoat→gloss coating→baking (180-250℃)→quality inspection The multi-layer spraying process consists of three sprays (referred to as three sprays), including primer, topcoat, and topcoat, as well as secondary sprays (primer, topcoat). 1. Purpose of pretreatment: Before spraying aluminum alloy profiles , the surface of the workpiece needs to undergo degreasing, decontamination, and chemical treatment to produce a chromized film, increase the adhesion and oxidation resistance between the coating and the metal surface, and is conducive to extending the service life of the paint film. 2. Primer coating: As a primer coating for sealing the substrate, its function is to improve the impermeability of the coating, enhance the protection of the substrate, stabilize the metal surface layer, strengthen the adhesion between the topcoat and the metal surface, and ensure the color uniformity of the topcoat coating. The thickness of the paint layer is generally 5-10 microns. 3. Top coat coating: The top coat coating is a key layer of the spray coating, which provides the decorative color required for the aluminum material, making the appearance of the aluminum material meet the design requirements, and protecting the metal surface from external environmental atmosphere, acid rain, pollution, and UV penetration. The anti-aging ability is greatly enhanced. The top coat is the thicker one in spraying, and the thickness of the paint layer is generally 23-30 microns. 4. Glossy paint coating: Glossy paint coating, also known as varnish coating, mainly aims to more effectively enhance the paint layer's resistance to external corrosion, protect the topcoat coating, increase the metallic luster of the topcoat color, make the appearance more vivid and dazzling, and the coating thickness is generally 5-10 microns. The total thickness of the three spray layers is generally 40-60 microns, and can be thickened if special needs arise. 5. Curing treatment: the three spray coating generally needs secondary curing. The aluminum materials are treated in the curing furnace. The curing temperature is generally between 180℃-250℃, and the curing time is 15-25 minutes. Different Fluorocarbon manufacturers will provide better temperature and time according to their own coatings. Fluorocarbon spraying plants (curium oil plants) also have their own experience in changing the two curing times during the three spraying to one curing. 6. Quality inspection: Quality inspection should follow the AAMA-605.02.90 standard. Strict quality inspection is essential to ensure high-quality spraying products.

Aluminum profiles are aluminum materials with different cross-sectional shapes obtained by hot melting and extrusion of aluminum rods. The production process of aluminum profiles mainly includes three processes: casting, extrusion, and coloring. Among them, coloring mainly includes processes such as oxidation, electrophoretic coating, fluorocarbon spraying, powder spraying, and wood grain transfer printing. Classification method for aluminum profiles 1、 It can be divided into the following categories according to its purpose: 1. Architectural aluminum profiles (divided into two types: doors, windows, and curtain walls) 2. Radiator aluminum profiles. 3. General industrial aluminum profiles: mainly used for industrial production and manufacturing, such as automated mechanical equipment, the framework of covers, and customized mold opening according to the requirements of various companies' mechanical equipment, such as assembly line conveyor belts, elevators, dispensing machines, testing equipment, shelves, etc., are mostly used in the electrical machinery industry and clean rooms. 4. Aluminum alloy profiles for railway vehicle structures: mainly used in the manufacturing of railway vehicle bodies. 5. Frame aluminum profiles, create aluminum alloy picture frames, and frame various exhibitions and decorative paintings. 2、 Classification by alloy composition Aluminum profiles can be classified into alloy grades such as 1024, 2011, 6063, 6061, 6082, and 7075, with the most common being the 6 series. The difference between different grades lies in the different proportions of various metal components. Except for commonly used building aluminum profiles such as 60 series, 70 series, 80 series, 90 series, curtain wall series, etc. for doors and windows, there is no clear model distinction for industrial aluminum profiles. Most production factories process them according to the actual drawings of customers. 3、 Typical uses of different grades of aluminum alloys 1050: Extruded coils, various hoses, fireworks powder for food, chemical, and brewing industries 5050: Thin plates can be used as inner lining plates for refrigerators and refrigerators, as well as for automotive air pipes, oil pipes, and agricultural irrigation pipes; It can also process thick plates, pipes, bars, irregular materials, and wires, etc 5154: Welded structures, storage tanks, pressure vessels, ship structures and offshore facilities, transport tanks 6010: Sheet: Automotive Body 6061: Various industrial structures with certain strength, weldability, and high corrosion resistance are required, such as pipes, rods, shapes, and plates for manufacturing trucks, tower buildings, ships, electric vehicles, furniture, mechanical parts, precision machining, etc 6063: Industrial profiles, building profiles, irrigation pipes, and extruded materials for vehicles, racks, furniture, fences, etc 6066: Forgings and welded structural extrusion materials

Aluminum profiles are aluminum materials with different cross-sectional shapes obtained by hot melting and extrusion of aluminum rods. The production process of aluminum profiles mainly includes three processes: casting, extrusion, and coloring (coloring mainly includes oxidation, electrophoretic coating, fluorocarbon spraying, powder spraying, etc.). Aluminum materials are extremely unstable in the air and can easily form oxide films that are difficult to recognize with the naked eye. Due to the different processing methods for aluminum parts, such as casting, direct cutting from extruded sheets, mechanical precision processing, or heat treatment or welding after different processes, the surface of the workpiece will present different states and varying degrees of dirt or marks. Therefore, in the pre-treatment process, the pre-treatment process must be selected based on the actual situation of the workpiece surface. In the pretreatment process, attention should be paid to: although the natural oxide film on the surface of the fine machined parts is only initially formed, the unmachined surface is left with an excessively thick oxide layer formed during the casting process, and a layer of oily sintered coke is formed before the workpiece is transferred to the heat treatment or welding process. The treatment precautions are as follows: (1) The problems to be noticed in the pretreatment process of fine machined parts: although the natural oxide film on the surface of fine machined parts has just formed and is easy to remove, it is greasy, especially in and around the eyelet (added due to lubrication needs during machining). Such parts must be cleaned with organic solvent first. If you directly use alkali, it is not only greasy and hard to remove, but also the fine machined surface can not withstand strong alkali corrosion for a long time, The result will also affect the roughness and tolerance fit of the workpiece surface, which may eventually become a waste product. (2) The issues that need to be noted in the pre-treatment process of casting molded parts. Not all surfaces of cast parts have undergone mechanical processing. Unmachined surfaces have an excessively thick oxide layer formed during the casting process, and some even contain sand layers. At this time, the original oxide film in this area should be removed first using machining or sandblasting methods, or processed after alkali washing. Only in this way can the original oxide layer in the unprocessed area be removed and the tolerance dimensions of the machined area be avoided from changing. (3) During the pre-treatment process of workpieces that have undergone heat treatment or welding, attention should be paid to the following issues: according to the process requirements, the workpieces need to be cleaned with organic solvents before being transferred to the heat treatment or welding process to remove surface oil stains. However, currently, this is generally not possible. Therefore, a ...

To this end, a reasonable product structure is designed through mechanical analysis, which can not only meet the usage requirements, but also have a simple and lightweight structure. 1.2 Design requirements: (1) Solar panel specifications: 1650mm×990mm×50mm (2) Number of solar panels installed: 14 ( 3) Solar panel array: 2×7=14 (4) Bracket tilt angle: 30° (5) Maximum wind speed: 42m/s (6) Snow load: 0.65kN/m2 (7) Solar panel load: 0.2kN/m2 (8) Installation conditions: Ground, ground roughness category II (9) Calculation standard: JIS C8955: 2011 (10) Product design life: 20 years 2 Strength design 2.1 Design conditions ①The snow load is 0.65kN/m2, and the maximum wind speed is set to: 42m/s. Seismic loads are not considered. It can be calculated that the vertical snow thickness is less than 1m, which is a calculation for ordinary places. ② According to the above, it can be assumed to be the maximum load in a general place, and the short-term composite load of the fixed load G and the wind pressure load W generated by the storm is used, that is, G+W; the load combination of G+S when there is snow. ③ Calculate the bending strength and bending amount of the material caused by the wind pressure blowing from the front of the bracket (downwind) and the wind pressure blowing from behind the bracket (headwind), and confirm the strength. ④ Maximum height H=2.175m. 2.2 Assumed loads ①Fixed load solar module: Gm =0.2kN/m2; Weight of T-shaped track 110: G2= 1.703×9.8/(1.65/2)=0.021kN/m2; Fixed load weight of single T-shaped track 110 G= 0.2+0.021=0.221kN/m2; ②Wind pressure load: Assume that the wind pressure load of the wind blowing from the front of the array (downwind) is Wp Wp=Cw×(0.6×V0 2 ×E×I) Cw—wind coefficient. This scheme is positive pressure. The calculation formula is: 0.65+0.009θ=0.65+0.009×30=0.92 V0—Wind speed 42m/s E—Environmental coefficient, since H=2.175m is less than Zb=5m According to formula (4), the ground roughness category is II Er=1.7×(Zb /ZG)α =1.7×（5/350）0.15=0.8988 E=Er 2 /m2 The wind pressure load of the wind (headwind) blowing from behind the array is Wp, and the wind coefficient is changed to: Cw—wind coefficient. This plan is negative pressure. The calculation formula is: 0.71+0.016θ=0.71+0...
