the widespread use of aluminum alloy doors and windows hollow glass is the symbol of the evolution of the times, and it is also the reason for the development of energy-saving buildings.
Insulating Glass is also called insulating glass, which is composed of two or more pieces of glass; Because the glass plate is separated by a partition frame, the edges around are sealed by welding or welding. Inert gas is injected in the middle, and desiccant is filled into the frame to ensure dryness. The energy-saving efficiency of insulating glass used in doors and windows is also very high. Let's learn about the energy transmission mode of insulating glass:
1. Radiation Transmission
rays include infrared rays, ultraviolet rays and so on, through which energy is transmitted in the form of radiation. Assembling insulating glass with reasonable spacing thickness according to specific conditions can effectively weaken the outdoor solar rays to transmit appropriate energy.
2. Convection transmission
when there is a temperature difference on both sides of the glass, the air on both sides will rise unevenly, resulting in air convection and energy loss. The reasons for this are: 1. The glass does not fit well with the surrounding seal. 2. The internal structure design of hollow glass is unreasonable. Reasonable design of hollow glass will reduce gaseous exchange.
3. Conduction transmission
conduction transmission is to drive energy movement through the movement of object molecules to achieve the purpose of transmission. And hollow glass is completed by glass and internal air. Active molecules such as water molecules in the air will affect the conduction and transmission performance of hollow glass energy to a high extent. Therefore, the important factor affecting the thermal insulation performance of insulating glass is the sealing performance.
After understanding the energy transfer mode of hollow glass, we can know that it can be reasonably matched with doors and windows and combined into a complete door and window system. It makes full use of the low energy consumption of hollow glass, and at the same time, it achieves the effects of energy saving, emission reduction and environmental protection.
