UV-Transmissive White Glass (BB) is a special type of optical glass that, unlike conventional glass which absorbs ultraviolet (UV) radiation, allows UV light to pass through while maintaining a white appearance. This type of glass is typically produced by adding specific chemical components during the melting process to minimize UV absorption, while maintaining its white color through the use of white pigments or titanium dioxide (TiO₂) and other additives.
Characteristics of UV-Transmissive White Glass (BB)
- UV Transmittance:
- UV Allowance: It allows both UVA and UVB wavelengths of light to pass through. This is crucial for applications requiring UV light, such as UV curing, photochemical reactions, UV disinfection, and certain scientific experiments.
- White Appearance:
- Color Maintenance: The glass maintains a white appearance, thanks to the addition of white pigments or titanium dioxide, ensuring that the glass remains visually white even when light is transmitted through it.
- Visible Light Transmission:
- Light Passage: In addition to UV light, UV-transmissive white glass also permits visible light to pass through. Depending on the formulation, its light transmission rate and color rendering index may vary.
- Versatile Applications:
- Broad Use: This glass finds applications in various fields including industrial, scientific, medical, and artistic domains.
Applications of UV-Transmissive White Glass (BB)
- UV Curing Technology:
- Curing Processes: In industries like printing, coatings, adhesives, and finishes, where UV light is used for rapid curing, UV-transmissive white glass can serve as a work surface or protective cover.
- Scientific Research:
- Experimental Use: In biological, chemical, and physical research, when experiments require UV light and observation of samples, UV-transmissive white glass can be used as part of experimental containers or equipment.
- Medical Devices:
- UV Disinfection: In medical instruments and equipment, UV-transmissive white glass can be utilized in UV disinfection devices, such as UV light boxes, to disinfect medical tools and surfaces.
- Art and Design:
- Aesthetic Applications: In contexts where unique visual effects are desired, such as in lighting fixtures, decorative items, or art installations, UV-transmissive white glass can create distinctive and eye-catching pieces, especially revealing different colors or patterns under UV light.
Manufacturing Process
The manufacturing of UV-transmissive white glass involves a precise process, requiring accurate control over the formulation and melting conditions to ensure the desired UV transmittance and white appearance under visible light. Manufacturers typically perform rigorous optical performance testing to verify that the glass meets the required specifications and application needs.
