Ultra-white float glass is a kind of flat glass with high transparency and low iron content. Due to its excellent optical performance and pure appearance, it is widely used in high-end buildings, solar energy, furniture, electronic products and other fields. The following is a detailed introduction to ultra-white float glass:
1. Characteristics
A. Low iron content
B. High light transmittance
C. Pure appearance
D. Excellent performance
2. Production process
Ultra-white float glass is made by the float process, but the raw materials and process control are stricter:
A. Raw material selection: High-purity quartz sand, soda ash, etc. are used, and iron impurities are strictly controlled.
B. Melting process: When melting at high temperatures, iron contamination should be avoided. Platinum channels or special refractory materials should be used.
C. Tin bath forming: The molten glass is spread out and polished in the tin bath to form a uniform thickness.
D. Annealing and Cutting: Slow annealing to relieve stress, then cut to standard size.
3. Application fields
A. Building curtain walls and skylights
B. Solar photovoltaic
C. Furniture and household Appliances
D. Electronic display
E. Artistic decoration
4. Strengths and Weaknesses
A. Advantages:
a. It has excellent light transmittance, enhancing the lighting and energy efficiency of buildings.
b. The color reproduction is realistic and it is suitable for display and optical applications.
c. It can be processed a second time.
B. Disadvantages:
a. The cost is relatively high, and the control over raw materials and production is strict.
b. High ultraviolet transmittance.
c. The surface is more prone to getting dirty and requires high maintenance.
Ultra-white float glass, with its "crystal-like" texture, has become an important material for modern high-end design and technological applications. Despite its high price, it is irreplaceable in scenarios where quality and aesthetics are pursued.
