What is the principle of insulation of aluminum foil tape?
Air-conditioning foil manufacturing air conditioner heat exchanger fin of special materials, the early use of air-conditioning foil is a prime foil. In order to improve the surface properties of plain foil, before forming coated with anti-corrosion coating of organic and inorganic hydrophilic coating to form hydrophilic foil.
Foil is actually outside temperature conduction, the temperature inside to protect from outside influence, in fact, cotton insulation is insulation. There are thermal insulation, waterproof, moisture and other functions. Its solar radiation absorption coefficient is very low, most of the heat transfer can be separated.
Aluminum foil itself is a good conductor of heat, directly above the package is basically not play the role of insulation, but also accelerate the loss of heat, so use the time at which wrapped some cotton insulation and then wrapped in aluminum foil.
