What are the factors that affect the performance of insulating glass:
1. The thickness of the gas spacer layer is mainly to prevent the formation of turbulent airflow inside the hollow glass by controlling the thickness, and the hot and cold airflow of the control gas interferes with each other, or controls the airflow of the rising and falling air to interfere with each other to control the generation thereof. Flow heat transfer.
2. The gas type and humidity between the gas layers are filled with inert gas inside the insulating glass, which can reduce the heat insulation and sound insulation properties of the insulating glass. For example, the argon gas and the sulfur fluoride can increase the heat insulation of the insulating glass. Sound insulation performance; the content of water vapor inside the hollow glass increases, which will cause internal condensation or even water, which will affect the aesthetic effect of the insulating glass, and will increase the conduction heat transfer coefficient of the insulating glass and reduce the heat insulation effect.
3. Edge sealing of insulating glass On the one hand, if the edge of the insulating glass is not well sealed, the proportion of water vapor entering the interior of the insulating glass through the sealing layer will increase, and the speed of failure of the insulating glass will also increase. Any product, no matter how good its initial performance, however, its life is very short, such a product can not be said to be a good product; on the other hand, if the edge material of the insulating glass has good thermal conductivity, then pass The heat transfer of the sealant connected to the glass at the edge of the insulating glass is relatively large, and the heat insulating coefficient of the insulating glass is improved, and the heat insulating performance is lowered.
4. Heat Transmittance of Glass In the above analysis, we can understand that if a reasonable space layer design and construction is adopted, the convection and conduction heat transfer through the insulating glass can be basically controlled. The heat transfer of the insulating glass is mainly carried out by means of radiation heat transfer. If ordinary transparent glass with high transmittance and low reflectivity is used, the insulating performance of the insulating glass is higher than that of the coated glass with high reflection and low transmittance or Low- E glass is much lower.
5. The plane size of the glass increases the plane size of the insulating glass, which can reduce the heat loss per unit area of ​​the insulating glass and improve the overall heat insulation effect of the insulating glass.
