Hollow two-cavity thermal insulation glass

Han film center glass is jointly developed by the State Key Laboratory of Organic/Inorganic Composite Materials and Chizhou Yingpai Technology Co., Ltd. It has excellent shading and heat preservation properties, and is currently the world's most energy-saving and environmentally friendly new glass product, which can satisfy Energy-saving standards for glass doors and windows of new buildings in any region.

Han film center glass is a combination of two ordinary white glass and one or more Han films (light-weight thermal insulation and high-transparent materials made of special nano materials and technology), separated into double cavities by spacers or The multi-cavity hollow structure greatly improves the heat insulation and heat preservation performance of the original ordinary insulating glass.

The current implementation of the new energy-saving standards for glass doors and windows makes it necessary to use triple-glass double-cavity hollow glass with active sunshades in most areas. This allows developers to increase the capital investment caused by changing load design and making active sunshades. The weight of the film-mounted glass is basically the same as the weight of the original double-glass hollow doors and windows. There is no need to change the load design of the original building, and the shading coefficient of the Han film has already met the sun-shading requirements for glass doors and windows stipulated in the new standard, which can save developers The series changes the cost of load design and production of active sunshades.

Performance advantages:

1. High transparency and high heat insulation: The SC value of the glass is adjustable between 0.35-0.6. Since the Han film used has the function of blocking more than 90% of the infrared heat, it uses the nano-characteristics of the new material to allow 80% of the visible light in the sun to pass through, ensuring natural lighting in the room. In summer, it absorbs and absorbs the radiant heat energy of direct outdoor air. Prevent entry into the room, reduce the cooling load of air conditioning, and reduce cooling energy consumption. At the same time, a high proportion of infrared heat radiated in the air and on the ground is blocked. The main load of air conditioning in cloudy and evening comes from these two aspects, and both are infrared radiation, so cloudy and evening also have excellent energy-saving effects. This is other internal , Functions that the external shading method does not have

2. High thermal insulation performance:

1. The nanometer characteristics of the Han film can effectively prevent the infrared heat generated by indoor heating from radiating to the outside, achieving the purpose of heat preservation and reducing heating energy consumption.

2. When the air interlayer is in a completely sealed state (hollow glass structure), the dry air in the air interlayer is relatively static, and the relatively still air is a poor conductor of heat, which reduces the rate of cold and heat exchange and has a better resistance to heat conduction The effect of the Han film center glass is to increase one or more air layers on the basis of double glass single cavity, so that the rate of cold and heat exchange is reduced to a lower level, achieving a higher level of insulation effect, and effectively improving the indoor glass The temperature of the surface prevents more heat conduction loss.

Combining the above two technologies, the heat transfer coefficient of the Han film center glass can be adjusted between 2.0-1.0.

3. The parameters can be determined: the Han film center glass with different transmittance, shading coefficient and heat transfer coefficient can be customized according to the needs of the project. All core technologies are the company's patents, and the company's R&D team has very strong R&D capabilities to ensure the leading position of the technology.

4. Unblocked wireless communication: The central glass of the Han film has no barrier to wireless signals, does not interfere with wireless signals such as mobile phones, and can maintain unobstructed communication. The materials used by Hanmo use semiconductor nano materials, not metal coating materials, and will not cause interference and shielding to mobile phone signals and wireless network signals.

5. Cost saving:

1. Reduce the burden on the wall: Because of its light and handy characteristics, the Hanmo central glass does not need to change the wall load-bearing design required for the original double-glass hollow, which can save the corresponding increase in the wall due to the use of doors and windows made of three or more pieces of glass Body weight-bearing cost.

2. Shading lightening: the central glass of the Han film has a great contribution to the overall shading coefficient of the whole window, saving the process and cost of other shading methods.

3. Reduce the burden on the window frame: In comparison, the strength of the window frame and hardware used for the lighter sash can be reduced by one level, saving the cost of the window frame and hardware components.

4. Window burden reduction: the same K-value Han film center-mounted glass is 1/3 lighter than three-glass two-cavity glass and 1/2 lighter than four-glass three-cavity glass, reducing transportation costs, labor costs and installation by more than 1/3 Risk etc.

6. Comfortable application:

1. The central glass with the same K value reduces the weight of the window sash, which is easy to open, and the user feels relaxed and comfortable when using it, and improves the comfort;

2. Noise blocking: The central glass window of Hanmo can eliminate the shortcomings of ordinary double-glass hollow glass resonance, has obvious noise blocking function, and reduces noise by about 30% compared with ordinary double-glass hollow glass;

3. No light pollution: The reflectivity of the glass window in the Han film is less than 15%, and there is no light pollution.

7. Long lifespan: Han film uses nano-oxide, which is stable in natural environment. After aging test, under the condition of 18 years of use in natural conditions, there is no discoloration, and the change of optical performance index is less than 1%.

8. Add highlights:

1. Ultraviolet blocking: The central glass window of Han film has 99% ultraviolet blocking function;

2. Prevent condensation: The thermal insulation performance of the glass in the Han film keeps the temperature difference on both sides of the hollow layer, thereby reducing the heat loss or accumulation of the glass. The internal temperature of the glass is close to the indoor temperature, which can prevent condensation.

9. Convenient production: It can be processed directly on the existing insulating glass production line.

10. Wide coverage: It is convenient for local processing and production, saving freight and labor costs.

Scope of application: Han film center-mounted glass is suitable for newly built or rebuilt buildings with high requirements for K value and SC, and new buildings with strict construction cost control. It is especially suitable for buildings with large sizes of doors and windows, and they are suitable for lighting and shading. Places with multiple requirements.
