With the introduction of national policies on green buildings, building energy conservation has attracted more and more attention. Some research data show that building energy consumption has accounted for one-third of the total energy consumption of society; In building energy consumption, 50% energy consumption is lost through doors and windows, and in doors and windows, glass accounts for about 80%.
At the same time, the waste water, waste gas and waste residue produced by energy production have seriously damaged the construction of social ecological civilization and the health of human settlements. In such a severe situation, it is imperative to accelerate the development of green energy-saving building materials represented by vacuum glass.
Vacuum glass, as its name implies, is to seal two or more pieces of glass, and leave a tiny space between the two pieces of glass to evacuate the air in the space and make it reach a vacuum state. As a new type of high-performance energy-saving glass product with remarkable energy-saving effect, vacuum glass has obvious advantages such as low heat transfer coefficient, high sound insulation performance, light and thin structure, etc.
It is an ideal energy-saving and environmental protection material, which can significantly improve the energy-saving standards of buildings, indoor environmental quality and other performance indicators, and improve the quality of buildings. Randy Machine's 100-person R&D team launched tempered vacuum glass Randy V glass in 8 years, which has seven advantages, such as extreme heat insulation and super silence. Compared with ordinary vacuum glass, its performance advantage is more significant.
Green energy saving
The high vacuum cavity of V-glass effectively blocks the heat transfer, and its heat insulation performance is 2-4 times that of insulating glass and 6-10 times that of single glass. Its performance can meet the requirements of international passive house for the heat transfer coefficient of door and window glass, which can not only greatly reduce the energy consumption in the construction field and the discharge of three wastes, but also reduce the symptoms of "air conditioning disease" such as dizziness and upper respiratory tract infection caused by long-term exposure to air conditioning environment.
Effective noise reduction
The high vacuum cavity of V-glass effectively blocks the sound transmission, and its sound insulation effect is far superior to that of insulating glass, especially for reducing the low-and medium-frequency noise (such as traffic noise and construction noise) with strong penetration. In the case that the density of urban buildings, traffic flow and shopping malls is increasing, and the noise is gradually becoming seriously polluted, the appearance of V-glass has far-reaching significance for creating a peaceful and harmonious living environment.
High security
The surface stress and granularity of V-glass meet the standard of tempered glass, and it has passed many safety tests such as wind pressure and impact performance. A single V-glass can bear a high sand column pressure of 1.7m, which is equivalent to a uniform load of 40 adults with an average weight of 70kg per square meter. V-glass's unique low-temperature flexible sealing process completely retains the safety characteristics of tempered glass, such as high strength and impact resistance. Even if the glass is broken, its honeycomb fine particles are not easy to hurt people.
As a new generation of energy-saving materials promoted by the state, Randy V-glass has not only achieved commercial mass production, but also been successfully selected into the recommended product catalogue of passive low-energy building products of the Ministry of Housing and Urban-Rural Development. In a passive house project in Urumqi, Xinjiang, Randy V-glass won unanimous recognition for its outstanding advantages such as extreme heat insulation and super silence.
Under the background of advocating green buildings around the world, V-glass products have won the favor of passive low-energy buildings because of their irreplaceable energy saving, which undoubtedly means a broader market prospect. At the same time, vacuum glass also has a very broad development prospect in green household appliances, transportation, military development and other application fields, and will make greater contributions to global energy conservation, green and environmental protection in the future.
