What are the aluminum foil bubble insulation film pipe insulation materials?
2021-08-06

I haven't talked about the types and construction methods of outdoor pipe insulation materials. In fact, I don't know much about them. The key is insulation and anti-corrosion materials. There are many kinds of insulation materials, but they are not widely used in pipes, which can achieve the purpose of insulation and anti-corrosion at the same time. Now we are going to teach you to choose insulation and anti-corrosion pipe insulation materials: aluminum foil insulation coil.

1. Aluminum foil bubble insulation film pipe insulation material

The solar absorptivity (solar radiation absorption coefficient) of aluminum foil bubble film is very low (0.03). It has excellent thermal insulation performance and can reflect more than 97% of radiated heat. It can be widely used in building roof and exterior wall insulation.

In addition, the number of bubble layers has little effect on the thermal conductivity of aluminum foil bubble film. When the bubble diameter is constant, the thermal conductivity of aluminum foil bubble film decreases with the increase of bubble height; when the bubble height is constant, the heat of aluminum foil bubble film causes the conductivity to decrease. As the bubble diameter increases, the thermal conductivity of aluminum foil bubble film decreases with the increase of bubble volume, and the thermal insulation performance increases.

2. Aluminum foil foam pipe insulation material

The insulation material, that is, the core layer of the aluminum foil foam insulation film is replaced by XPE or EPE foam, but the insulation performance is better than that of the bubble.

3. Aluminum foil fiberglass cloth

In fact, the general aluminum foil fiberglass cloth pipe insulation material has the function of high temperature resistance, but the heat insulation effect is not good. But it can be combined with other materials (bubble film, XPEPE foam). After the aluminum foil fiberglass cloth is compounded, it has the functions of high temperature resistance, heat insulation and heat preservation.
