Curtain wall aluminum panels are mainly composed of panels, ribs and corners. The corner code can be directly bent and stamped from the panel, or it can be formed by riveting the corner code on the small side of the panel. The reinforcing rib is connected with the electric welding screw behind the panel (the screw is directly welded on the back of the panel) to make it a solid whole, アルミベニヤカーテンウォールの強度と剛性を大幅に向上させ、長期使用時の平坦性を確保します。. 程度と耐風耐震性. 防音・断熱が必要な場合, アルミ板の内側に効率の良い遮音・断熱材を施工可能.

Aluminum curtain wall structure

アルミ化粧板は仕様によって2種類に分けられます: 厚さ以下のアルミニウムベニヤ 1.2 mmはアルミニウムバックルプレートと呼ばれます (アルミ角板とも呼ばれます), 厚さ以上のアルミニウムベニヤ 1.5 mmはアルミベニヤと呼ばれます (アルミ角板とも呼ばれます) アルミカーテンウォール).

Classification of aluminum curtain wall

現在使用されているアルミカーテンウォールに関しては, それらのほとんどは複合アルミニウムパネルとアルミニウム合金ベニヤです。.

The composite aluminum plate is made of two layers of 0.5mm pure aluminum plate inside and outside (0.2-0.25mm for indoor use), and the middle layer is made of polyethylene (PE or polyvinyl chloride PVC) with a thickness of 3-4mm. Flat plate, のような 4アルミシート×8 (1220mm×2440mm). The fluorocarbon paint on the surface of the composite aluminum plate for external use is also completed by roller coating, rolling and heat sealing at one time. The thickness of the coating is generally about 20 μm. The advantages of the composite aluminum plate are light weight, smooth surface, good flatness, and the same direction It has no color difference and has excellent on-site processability, which provides conditions for dealing with the size change of the outer wall caused by the on-site construction error, reducing the processing cycle of the workshop and shortening the installation period.

Composite aluminum plate

The aluminum alloy veneer is generally 2~4mm aluminum alloy plate. When it is made into a wall panel, the sheet metal processing is carried out according to the requirements of the secondary design, and the edge is directly folded. The four corners are welded into a close groove by high pressure. The wall panel The fixing bolts for the reinforcing ribs are reserved on the back by means of electric welding nails. After the sheet metal work is completed, the fluorocarbon paint is sprayed. 一般的に, there are two coats and three coats, and the thickness of the paint film is 30-40μm. The aluminum alloy veneer is easy to process into arcs and multiple folded edges or sharp angles, which can meet the needs of today’s ever-changing exterior wall decoration, and it is rich in colors, which can be arbitrarily selected according to the design and the owner’s requirements, which truly broadens the scope of architects. their design space.

Aluminum veneer curtain wall

Aluminum curtain wall Features:

1. Aluminum curtain wall has good rigidity, light weight and high strength. The aluminum veneer curtain wall panel has good corrosion resistance, and the fluorocarbon paint can last for 25 色褪せることなく何年も.
2. The aluminum curtain wall has good craftsmanship. 加工後に塗装する工程を採用, the aluminum plate can be processed into various complex geometric shapes such as plane, 円弧面と球面.
3. The aluminum curtain wall is not easy to stain, 掃除とメンテナンスが簡単. The non-adhesiveness of the fluorine coating film makes it difficult for pollutants to adhere to the surface, and it has good cleanliness.
4. The installation and construction of aluminum curtain wall is convenient and quick. The aluminum plate is formed in the factory, and the construction site does not need to be cut but simply fixed.
5. The aluminum curtain wall can be recycled and reused, 環境保護に有益です. Aluminum plate can be 100% recycled, and the recycling value is higher.

Aluminum sheet for aluminum curtain wall

Aluminum curtain wall has unique texture, rich and long-lasting color, and can be diversified in appearance and shape, and can be perfectly combined with glass curtain wall materials and stone curtain wall materials. Its perfect appearance and excellent quality make it favored by owners. Its light weight is only one-fifth of marble and one-third of glass curtain wall, which greatly reduces the load of building structure and foundation, 維持費も安い, 高いパフォーマンスと価格の比率.

Aluminum curtain wall surface treatment process

Fluorocarbon resin spraying

アルミニウムカーテンウォールの表面は、通常、クロムおよびその他の前処理で処理されます。, その後、フロロカーボンスプレーによる処理を行います。 (PVDF). ポリフッ化ビニリデン樹脂 (500大佐) for fluorocarbon paint topcoats and varnishes. Generally divided into two coatings, three coatings or four coatings.

Aluminum coil for aluminum curtain wall

Fluorocarbon coating has excellent corrosion resistance and weather resistance, 酸性雨に耐えられる, 塩水噴霧およびさまざまな大気汚染物質, 耐寒性、耐熱性に優れています, can resist strong ultraviolet radiation, and can maintain long-term non-fading and non-chalking ,long lasting.
Huawei Aluminum selects high-quality fluorocarbon coatings from world-renowned fluorocarbon coating manufacturers such as PPG, DNT, AKZO, and NIPPON. It has a wide range of color options. Customers can directly choose according to the color swatches provided by the manufacturer or provide swatch samples.

陽極酸化処理

The anodized oxide film is generally above 12μ, and the colors are only bronze and white. The color is monotonous. さらに深刻な欠点は、各アルミ板の色が異なることです。. とても醜い.

この欠点は解消できない, 生産技術に起因するものではありません, ただしアルミ板はバッチナンバーではないので, 化学組成には小さな違いがあります, また、酸化時の電解槽の電流密度などの要素も全く同じにすることはできません。, 酸化後の色には多少の違いがあります, 個別に見ると明らかではないかもしれません, しかし、それらをすべて一緒に並べると非常に明白です. したがって, アルミニウムカーテンウォールのアルミニウム板の表面処理は陽極酸化されてはなりません.

Electrostatic spraying

アルミニウムカーテンウォールの表面処理のもう一つの方法は静電スプレーです。. Spraying is divided into powder spraying and liquid spraying. Powder coating materials are mainly polyurethane, expansion resin, epoxy resin and other raw materials combined with high color retention pigments, and dozens of spray powders of different colors can be obtained. The sprayed powder is impact-resistant and wear-resistant. Under the impact of 50kg, the aluminum plate is deformed, and the sprayed coating has no cracks, no peeling, intact, resistant to dilute acid, and resistant to mortar.

The only disadvantage is that it is afraid of long-term exposure to ultraviolet rays, and it is easy to produce yin and yang color difference after a few years.
