PVD anodizing aluminum mirror sheet

PVD anodizing aluminum mirror sheet introduction

PVD (Physical Vapor Deposition) anodizing aluminum mirror sheets is a process where a thin layer of material is deposited onto the surface of the aluminum through a vacuum deposition process. PVD coating can enhance the appearance, durability, and corrosion resistance of aluminum surfaces, including mirror sheets.

Huawei Aluminum provides PVD anodizing aluminum mirror sheet with a reflectivity of up to 99%. We can adjust the reflectivity of the product by controlling the thickness of PVD.

PVD anodizing aluminum mirror sheet production process

• Cleaning and Preparation: The aluminum mirror sheets are cleaned thoroughly to remove any contaminants or residues that could affect the adhesion of the PVD coating.
• Vacuum Chamber: The cleaned aluminum mirror sheets are placed inside a vacuum chamber. This chamber is then evacuated to create a vacuum environment.
• Target Material Evaporation: Inside the vacuum chamber, the target material (often a metal or a metal compound) is evaporated using various techniques such as sputtering or evaporation. This material is deposited onto the surface of the aluminum mirror sheet.
• Film Formation: The evaporated material condenses onto the surface of the aluminum mirror sheet, forming a thin film. The thickness and properties of this film can be controlled precisely during the deposition process.
• Annealing (Optional): In some cases, after the deposition, the coated aluminum mirror sheets may undergo annealing to improve the adhesion, density, and stability of the PVD coating.
• Inspection and Quality Control: Once the coating process is complete, the coated aluminum mirror sheets are inspected for uniformity, adhesion, and other quality parameters to ensure they meet the desired specifications.

Advantages of PVD anodizing aluminum mirror sheet

Excellent corrosion resistance:

The anodizing process generates a dense aluminum oxide (Al₂O₃) film on the surface of the aluminum plate, which enhances the aluminum plate’s resistance to the atmosphere, chemical substances and moisture, and significantly improves its corrosion resistance.

High strength and wear resistance:

The high hardness of the anodized film makes the surface of the aluminum plate have good wear resistance and can resist scratches and wear during daily use, maintaining long-term beauty.

Excellent mirror effect:

PVD coating technology can deposit an ultra-thin and uniform metal or alloy film, such as titanium, chromium, zirconium, titanium nitride, etc., on the surface of the aluminum plate to form a mirror effect with high reflectivity. This mirror effect is not only beautiful, but also enhances the brightness and visual openness of the indoor space.

Rich color options:

PVD coating can adjust coating materials and process parameters as needed to achieve a variety of color choices, including primary metal colors, gold, rose gold, black, bronze, etc., to meet personalized and high-end design needs.

Environmentally friendly and pollution-free:

The PVD coating process is a green surface treatment technology with low temperature, low energy consumption and no wastewater discharge. It is environmentally friendly and meets the requirements of modern sustainable development.

Excellent weather resistance:

The PVD coating layer is stable, not easy to fade, and is not affected by ultraviolet radiation. Even if it is used for a long time in an outdoor environment, it can maintain a bright color without peeling or rusting.

Excellent adhesion and abrasion resistance:

There is good bonding force between PVD coating and anodized film, making the coating firmly adhere to the surface of the aluminum plate and not easy to fall off. At the same time, the PVD coating itself has high hardness and wear resistance, further enhancing the scratch resistance of the aluminum plate surface.

Easy to clean and maintain:

The mirror aluminum plate has a smooth surface and is not prone to dust accumulation. When cleaning, you only need to wipe it gently with a soft cloth to restore its original luster, reducing maintenance costs.

Wide applicability:

PVD anodized mirror aluminum sheets are widely used in many fields such as interior and exterior building decoration, high-end furniture, display racks, lighting fixtures, elevator decoration, automotive interiors, and electronic product casings due to their excellent decorativeness and functionality.

Typical applications of PVD anodizing aluminum mirror sheet

High reflectivity aluminum mirror sheets find diverse applications across various industries due to their exceptional optical properties.Such as, Tubular Daylighting Devices (TDD),solar power systems,satellite reflectors and telescopes, and so on.

Overall, the versatility, durability, and high reflectivity of aluminum mirror sheets make them indispensable in a wide range of applications, driving innovation and efficiency across industries.

Tubular Daylighting Devices (TDD)

Using PVD anodizing aluminum mirror sheet in Tubular Daylighting Devices (TDD) is a smart choice for maximizing light transmission efficiency.

These mirror sheets are specifically designed to have excellent reflective properties, which means they can efficiently redirect sunlight into the TDD system, illuminating interior spaces with natural light.

PVD anodizing aluminum mirror sheet for Solar Power System

PVD (Physical Vapor Deposition) anodizing aluminum mirror sheets offer several advantages when used in solar power systems:

• 1. Enhanced Reflectivity: PVD anodizing can enhance the reflective properties of aluminum mirror sheets, allowing them to efficiently reflect sunlight onto solar panels. This maximizes the amount of sunlight captured by the solar cells, increasing the overall energy output of the system.
• 2. Improved Durability: Anodizing aluminum through PVD creates a hard, durable surface layer that enhances the material’s resistance to corrosion, abrasion, and weathering. This ensures that the mirror sheets maintain their reflective properties over an extended period, even when exposed to harsh outdoor conditions.
• 3. Temperature Resistance: PVD anodized aluminum mirror sheets can withstand high temperatures, which is important in solar power systems where the mirrors may be subjected to intense sunlight and heat. The anodized surface helps dissipate heat more effectively, preventing degradation of the reflective coating.
• 4. Reduced Maintenance: The durable and corrosion-resistant nature of PVD anodized aluminum mirror sheets reduces the need for frequent maintenance. This lowers the overall maintenance costs of the solar power system and ensures consistent performance over time.
• 5. Customizable Finishes: PVD anodizing can produce a wide range of surface finishes and colors, allowing for customization to match the aesthetic requirements of the solar power installation. This flexibility in design can enhance the visual appeal of the system while maintaining high reflectivity.
• 6. Environmental Benefits: PVD anodizing is an environmentally friendly process that produces minimal waste and emissions compared to traditional surface treatment methods. This aligns with the sustainable principles of solar energy production and contributes to a cleaner environment.
