In terms of ventilation and ventilation, the flexible aluminum foil duct has better ventilation performance and can effectively transmit air and keep indoor air fresh and circulated. In some special occasions, such as places with high fire protection requirements, aluminum foil hoses have obvious advantages in fire protection performance.
In China, aluminum foil is used as insulation material outside air-conditioning ducts. In developed countries and regions, composite materials of aluminum foil, plastic and woven fiber are also used as insulation layers on building roofs. This material has good insulation effect and long service life.
The inside and outside of the aluminum foil are made of golden aluminium foil paper, fiberglass cloth and steel wire. It can be made into square, round, composite and thermal insulation types. It has good flame retardant performance and telescopic effect, and is used for ventilation in high-rise buildings. Aluminum foil insulation hose is filled with glass wool between the inner and outer layers of aluminum foil, which can insulate the air passing through it.
The air conditioning aluminum foil hose can maintain a constant temperature for the transported gas. No matter what changes occur in the outside world, its internal temperature is very stable. Moreover, this type of material also has anti-static properties and will not be affected by leakage. The important thing is that this type of product will not rust and will not have any impact on the gas inside, so you don't have to worry about the gas being contaminated and damaged during use.
The used aluminum alloys include 1100, 3003 and 8011. 3003 aluminum foil is a representative product of the 3 series aluminum-manganese alloy, also called anti-rust aluminum coil. It is mainly used in pipes, building roofs and walls as insulation materials, etc. Generally, 3003 aluminum coils with a thickness of 0.4-1.0mm are used for thermal insulation.
1100 aluminum foil is 1 series industrial pure aluminum, which contains more than 99.0% aluminum. It has strong conductivity, good formability, corrosion resistance, low strength, and cannot be strengthened by heat treatment.
Al-Fe-Si element is added to 8011 aluminum foil, with a tensile strength of 125 to 165, a yield strength of 110, and an elongation of 2 to 5. 8011 aluminum alloy is commonly used as aluminum foil, but not commonly used as aluminum plate. It has excellent performance and is a main industrial aluminum foil.
