Classification of Safety Glass:
First, Architectural Glass
1. Construction Laminated Glass
Currently, there are two main types of laminated glass used in construction: wet lamination and dry lamination. Wet lamination is a traditional method using adhesive, while dry lamination typically involves EVA or PVB films. Although both have their advantages, they also come with significant drawbacks. Wet-laminated glass lacks sufficient strength and often suffers from issues like yellowing, delamination, and bubbles, which has led to its gradual decline in the market. PVB-laminated glass, on the other hand, offers better strength but requires expensive equipment such as a roller press and autoclave, making it unsuitable for small and medium enterprises. EVA-laminated glass, however, provides a more efficient and cost-effective solution. It’s easy to process, has lower initial investment, and produces high-quality glass without common defects, making it a growing favorite in the construction industry.
2. Curved Laminated Glass
Curved laminated glass is commonly used in curtain walls, windows, columns, and spiral staircases. The market currently features hot-bent laminated glass and bent steel laminated glass. Previously, PVB film was the standard, but this method is complicated and costly due to the need for silica gel strips, constant temperature chambers, and autoclaves. This makes it less practical for large-scale architectural projects. In contrast, EVA film allows for a simpler and faster process, similar to flat lamination, leading to increased adoption in the market.
3. Bulletproof Glass
Used primarily in bank counters, bulletproof glass can be made using wet lamination, EVA, or PVB films. All three methods can produce certified bulletproof glass. However, EVA-based bulletproof glass is increasingly preferred due to its superior safety performance and ease of processing.
Second, Art Glass
1. Clip Real Glass
Originally developed in South Korea, real flower glass has gained popularity in China since its debut at an exhibition in Shanghai in 2009. Its unique patterns and high-end appeal make it a desirable choice for luxury interiors.
2. Wire Cloth Glass
Wire cloth glass features a silk or fabric layer between two pieces of glass, often used in bedroom partitions for aesthetic and safety purposes. Due to the risk of air bubbles in wet-processed versions, EVA film is now the preferred method, offering better quality and greater market potential.
3. Color Laminated Glass
Color laminated glass replaces traditional painted glass by sandwiching colored films between two glass panes. It offers vibrant color and improved safety, commonly used in KTVs, hotels, and high-end interiors.
4. Coffee Table Glass
Coffee table glass, originating from Shandong, uses amber or marbled materials between two glass layers. Its elegant appearance and reasonable price make it a popular choice in home decor.
5. Tempered Glass
Tempered glass features a reinforced layer that enhances safety and aesthetics. With a variety of designs and high durability, it is widely accepted in the market.
6. Closet Doors
Closet doors combine glass and MDF with a bonding film, offering a stylish and safe option. Using 2mm–3mm tempered glass improves the visual effect and is well-received in the market.
7. Marble Laminated Glass
Marble laminated glass combines natural marble between two glass layers, creating a stunning visual effect under different lighting. It is ideal for high-end spaces and offers excellent profit margins.
Third, New Energy
1. Solar Photovoltaic Panels
Solar panels consist of silicon cells and circuit boards. Traditionally made with lamination machines, these were expensive and inefficient. EVA lamination technology now offers a simpler and more cost-effective alternative, becoming the preferred choice in the industry.
2. Conductive Glass
Conductive glass includes a conductive layer between two glass panes, enabling control via AC power. It is widely used in premium products, especially in European and American markets.
3. LED Glass
LED glass features LED boards between two glass layers, allowing it to display signals when powered. It is commonly used in aviation, including all Southern Airlines aircraft.
4. Electric Glass
Electric glass incorporates heating elements and films between two glass panes, mainly used on trains to prevent fogging and improve visibility and safety.
