Nano yellow tungsten oxide may be applied for producing window heat insulation film, which may help you solve the following problems:
1. The windows are dazzling: Sunlight passes through the windows, and dazzling sunlight makes you difficult to work and rest in peace.
2. Serious light pollution: The lights of the opposite building are too strong, which affect your mood;
3. The glass house is too hot: The heat conduction of the glass is obvious in summer and the temperature is extremely high;
4. Electricity consumption in air conditioning soars: In the summer, air conditioning energy consumption is high to reduce indoor temperature.
The ultraviolet rays and near-infrared rays in the sunlight are the source of heat. And the direct result of ultraviolet radiation on human skin for a long time is that the skin becomes dark, which accelerates the aging of the skin. While this type of heat-insulating glass can protect your skin from heat by blocking ultraviolet rays, near-infrared rays, and strong light. And it softens the light in the room.
