Ultra white glass is a kind of ultra transparent low iron glass, also known as low iron glass and high transparent glass. It is a new high-grade glass variety with high quality and multi-function, with a light transmittance of more than 91.5%. It has the characteristics of crystal clear, high-grade and elegant. It is known as the “crystal Prince” of the glass family. Ultra white glass has all the processability of high-quality float glass at the same time, and has superior physical, mechanical and optical properties. It can be processed like other high-quality float glass. Unparalleled superior quality and product performance make ultra white glass have broad application space and bright market prospects.
Concept introduction
In the world, only a few enterprises such as PPG in the United States, Saint Gobain in France, Pilkington in the United Kingdom, Asahi nitrate in Japan, China Southern glass, Taiwan glass, Xinyi Group and Jinjing glass have mastered the production technology of ultra white glass. The high price and excellent quality make ultra white glass a symbol of the identity of buildings.
Unique advantages
1. The self explosion rate of glass is low
Because the raw materials of ultra white glass generally contain less impurities such as NIS and are finely controlled in the melting process of raw materials, the ultra white glass has more uniform composition and less internal impurities than ordinary glass, which greatly reduces the possibility of self explosion after tempering.
2. Color consistency
Because the iron content in raw materials is only 1 / 10 or even lower than that of ordinary glass, ultra white glass absorbs less green and purplish red bands in visible light than ordinary glass, ensuring the consistency of glass color.
3. High visible light transmittance and good permeability
6mm thick glass has a visible light transmittance of more than 91%, with crystal clear crystal quality, which makes the exhibits more clear and highlight the true appearance of the exhibits.
Ultraviolet light should be removed. General ultra white glass does not have this feature, and the ultraviolet transmittance is higher than that of ordinary glass.
4. Large market, high technical content and strong profitability
Ultra white glass has relatively high scientific and technological content, difficult production control and strong profitability compared with ordinary glass. The high quality determines its expensive price. The price of ultra white glass is 1 ~ 2 times that of ordinary glass, and the cost is not much higher than that of ordinary glass, but the technical barrier is relatively high and has high added value.
application area
The product characteristics of ultra white glass also set an application field for ultra white glass.
High end market
Ultra white glass with crystal luster, clear brightness and good light refractive index is also widely used in the high-end market. For example, the interior and exterior decoration of high-end buildings, high-end horticultural buildings, high-end glass furniture, all kinds of imitation crystal products and cultural relics protection display, high-end gold jewelry display, high-end shopping malls, shopping center space, brand stores and so on
Technology products
Ultra white glass is also used in some scientific and technological products, electronic products, high-grade car glass, solar cells and other industries because of its good light transmittance. The development and application of solar energy will also provide huge business opportunities for the development of ultra white glass – the glass substrate of solar photovoltaic power generation system needs to use ultra white glass, because the transmittance of ultra white glass is more than 92%.
building
For example, the National Grand Theatre in Beijing uses super white glass from Saint Gobain, France, Shanghai Opera, etc.
classification
Solar ultra white calendered glass
Solar ultra white calendered glass components can absorb the radiant heat of solar energy to the greatest extent and greatly improve the photoelectric conversion efficiency of solar cells. This glass can also resist the radiation of the sun’s ultraviolet rays, and the transmittance does not decrease. This can extend the service life of the cover glass more effectively, and the alkali resistance, anti mildew ability and anti-aging performance of all the environments are enhanced than that of the ordinary panel super white glass, so that the solar energy battery module cover glass is more conducive to protecting the silicon crystal plate under its own strength from being damaged by the outside and durable.
Ultra white transparent flat glass
Ultra white transparent flat glass (commonly known as “crystal glass”) It is a new type of transparent flat glass product developed and manufactured here. It is a flat glass with extremely low iron compound content produced by the melting and forming process of flat glass by using high-tech means to effectively reduce iron oxide in the optimization and processing of raw materials. Ultra white transparent flat glass has the appearance characteristics similar to colorless crystal. No matter viewed from the front or side, it has no green visual effect like ordinary flat glass. At the same time, it also has higher visible light transmittance and transparency than ordinary transparent flat glass.
purpose
Ultra white glass can be processed like other float glass, such as toughening, bending, gluing, hollow assembly, etc. The superior visual performance of ultra white glass will greatly improve the function and decorative effect of these processed glass. Therefore, ultra white glass has a wide range of applications and broad market prospects.
In foreign countries, ultra white glass is mainly used in high-grade buildings, high-grade glass processing and solar photoelectric curtain walls, as well as high-grade glass furniture, decorative glass, imitation crystal products, lamp glass, precision electronics industry (copier, scanner), special buildings, etc.
In China, the application of ultra white glass is expanding rapidly, and it has been applied in high-end buildings and special buildings. For example, ultra white glass has been applied in hundreds of projects, such as Beijing National Grand Theater, Beijing Botanical Garden, Shanghai Opera House, Shanghai Pudong Airport, Hong Kong Convention and Exhibition Center, Nanjing China Art Center and so on. Ultra white glass has also been widely used in high-grade furniture and high-grade decorative lamps. At the furniture and processing machinery exhibition held in Beijing, many glass furniture choose ultra white glass.
As a substrate material, ultra white glass provides a broader development space for the development of solar energy technology with its unique high transmittance. Using ultra white glass as the substrate of solar photothermal and photoelectric conversion system is a breakthrough in solar energy utilization technology in the world, which greatly improves the photoelectric conversion efficiency. In particular, China has begun to build a new solar photovoltaic curtain wall production line, which will use a large number of ultra white glass.
Supply and demand situation
Demand for ultra white glass: 3 million heavy containers in 2009 and 5.5 million heavy containers in 2010. Mainland and Taiwan film enterprises will usher in the first development peak in the second half of 2009 and 2010. It is expected that the production capacity will be close to 400MW by the end of 2009 and 1000MW in 2010.
The main sales targets of the company’s ultra white glass are amorphous film enterprises using Oerlikon equipment, domestic amorphous film enterprises and CIGS film enterprises. In the future, enterprises of Amat equipment are likely to join the demand side of ultra white glass.
Development prospect
Due to the high scientific and technological content and difficult production, ultra white glass is expensive, which is 5 ~ 10 times that of ordinary glass, but the cost is only 2 ~ 3 times that of ordinary glass, which has high added value. Ultra white glass accounts for 20%-30% of the total cost of thin film batteries. In the world, only a few enterprises such as PPG in the United States, Saint Gobain in France, Pilkington in the United Kingdom and Asahi Salter in Japan have mastered the production technology of ultra white glass, among which PPG has the most mature technology. In order to ensure the relative monopoly of the market, most of these glass giants adopt the means of technical blockade, do not transfer technology and adopt the marketing mode of production restriction, which makes ultra white glass have a high entry threshold in technology and capital.
The high price and excellent quality make the super white glass a symbol of the identity of the building. From the worldwide sales situation, only those high-end hotels, urban landmark buildings, government financial projects and large-scale high-end exhibition venues can use ultra white glass, such as Beijing’s bird’s nest, water cube, China History Museum, National Grand Theater, Shanghai Song theater and other well-known domestic buildings.
