In the realm of architecture, the use of titanium materials is increasingly widespread. From roofs and curtain walls to walls, decorations, and even sculptures, titanium's unique corrosion resistance offers novel solutions for construction. However, as time progresses and people's aesthetic standards rise, the reflectivity and decorative aspects of titanium surfaces have become focal points of attention.
To diminish reflectivity and prevent glare, various surface treatment techniques are commonly employed:
Polishing and Rolling Method
During the final stage of titanium rolling, the surface is processed with textured rollers, imparting a glossy appearance while reducing reflectivity.
Acid Etching Method
Acid etching is a primary means of enhancing the brightness of titanium and its alloy construction materials. By using different ratios of nitric acid and hydrofluoric acid, the titanium surface is dissolved, resulting in a whitish hue.
Composite Method
Employing a combination of polishing and rolling with acid etching, the composite treatment yields a white surface with a hint of titanium's inherent metallic color. This technique has gained popularity in recent years, particularly in large-scale buildings.
Sandblasting Method
High-speed sandblasting is utilized to create a finely textured surface on titanium, reducing its glossiness and producing a gray coloration.
Anodizing with Coloring
To achieve a vibrant appearance, anodizing with coloring is applied to the titanium surface. This process employs an anodizing apparatus, which applies direct or alternating current. By adjusting the voltage, the titanium surface can exhibit an array of colors, including gold, reddish-purple, purplish-blue, yellow, purple, blue, teal, and lime green. This captivating coloration enhances the visual appeal and creativity of the entire structure.
Looking ahead, with continuous innovation and refinement of titanium surface treatment techniques, titanium building materials are expected to become an integral part of modern architecture. They will contribute to the creation of visually appealing, durable, and environmentally friendly built environments.
