Insulating film to prevent sunlight reflection
There are three basic ways of heat transfer: heat conduction, convection, and radiation. Most of the heat transfer in buildings is the result of a combination of three methods. Jibao reflective insulation film, which radiates very little heat, is widely used in the insulation of roofs and walls.
Heat transmission route (without reflective film): heating source—infrared magnetic wave—heat energy increases the temperature of tiles—tile becomes a heat source and emits heat energy—heat energy increases the temperature of the roof—the roof becomes a heat source and emits heat energy—the indoor ambient temperature continues Elevated.
Heat transmission route (with reflective film): heating source—infrared magnetic wave—heat energy increases the temperature of tiles—tile becomes a heat source and emits heat energy—heat energy increases the surface temperature of aluminum foil—aluminum foil emits extremely low emissivity and emits a small amount of heat energy—indoor Maintain a comfortable ambient temperature.
It can be installed on the roof, wall or floor to block the thermal energy of the building from the outside. It has walls to withstand sudden increases and drops in temperature.
Use
1. Roof, wall, floor;
2. Air conditioner and water heater jacket;
3. Protect the outer layer of water pipes and ventilation pipes.
Aluminized film is a composite flexible packaging material formed by coating a thin layer of metal aluminum on the surface of a plastic film. The commonly used method is the vacuum aluminum plating method, which is to melt and evaporate the metal aluminum at high temperature under high vacuum. , The aluminum vapor is deposited on the surface of the plastic film, so that the surface of the plastic film has a metallic luster. Because it has the characteristics of plastic film and metal, it is a cheap, beautiful, high-performance, and practical packaging material.
