[China Aluminum Industry Network] Aluminum profiles are widely used in buildings, doors, windows, curtain walls and other products for many years due to their small specific gravity, easy processing, and large mechanical strength. Aluminum is a more active light metal with silvery white luster, and its corrosion resistance has the following two characteristics:
The higher the purity, the better the corrosion resistance, mainly because pure aluminum reacts with oxygen in the air, producing a thin and dense natural oxide film on the aluminum surface, which is faster and thicker than other metal oxide films. , Which prevents further corrosion of harmful gases and moisture in the air and plays a protective role;
Aluminum profiles have high mechanical strength but low corrosion resistance. The corrosion resistance of pure aluminum is good, but its mechanical strength is poor, which restricts the application of aluminum to a certain extent. For this reason, people add appropriate amounts of magnesium, copper, zinc, and other metals into aluminum to make various types of aluminum. Aluminum alloys greatly increase the mechanical strength of aluminum and greatly expand its application range, but its corrosion resistance is worse than that of pure aluminum, and therefore it may be corroded by oxidation. This requires powder coating to protect the aluminum profiles.
In addition to high corrosion resistance, powder-coated aluminum profiles have many advantages such as color diversification, good surface texture, etc., echoing with various colors of architectural exterior paints to adapt to different architectural styles.
Right Angle Prisms are used to direct beams at 90 degrees by using hypotenuse face in total internal reflection (TIR). The right angle prisms are often preferable to an inclined mirror in applications involving severe acoustic or inertial loads, because they are easier to mount, and deform much less than mirror in response to external mechanical stress. As long as acceptance angle limitations for TIR from the roof faces are not exceeded, the right angle prisms can serve as a retro reflector, turning beams back to the original direction.
Available in sizes ranging from 3 mm to 60 mm, Right-Angle Prisms can be used to deviate a light path by 90° or 180°, depending on which surface is used as the input for the light source.
Right angle prisms are used to redirect light beams at 90 degrees. Right angle prisms are made of BK7, UVFS optical materials.
- 45-45-90 degree prisms
- Can be used as internal or external reflectors or as retro - reflector
