Yana da tabbacin cewa foil na aluminum da kansa ba shine insulator mai kyau ba, saboda aluminum foil iya gudanar da wutar lantarki.
Aluminum foil yana da ingantattun kaddarorin rufewa. Kodayake foil na aluminum yana da wasu kaddarorin rufewa a wasu lokuta, Abubuwan da ke rufe su ba su da kyau kamar sauran kayan rufewa. Domin a karkashin yanayi na al'ada, the surface of aluminum foil is susceptible to oxidation or corrosion, forming conductive oxides or corrosion products, thereby reducing its insulation performance.
There is a close relationship between the conductivity and purity of aluminum foil. Gabaɗaya magana, the higher the purity of the aluminum foil, the better its electrical conductivity and the higher its conductivity. Saboda haka, in practical applications, aluminum foil is usually not used as an insulating material, but is more often used to make conductive parts or as a conductive material.
Aluminum foil is conductive. The conductivity of aluminum foil depends on its manufacturing process and purity. Gabaɗaya magana, the higher the purity of the aluminum foil, the better the electrical conductivity and the higher the conductivity. Under standard temperature and pressure, the conductivity of aluminum foil is usually between 35-50MS/m.
A gaskiya, aluminum is known for its excellent thermal conductivity because it conducts heat so well. Duk da haka, when used as a radiant barrier or reflective insulation, aluminum foil can effectively reduce heat transfer by reflecting radiant heat. If aluminum foil is placed with the light side facing out in an area where heat is to be reflected, such as behind a radiator or a window, it can help reflect radiant heat back into the room, potentially improving energy efficiency.
Although aluminum foil is not a good insulator in the traditional sense, it serves a very important purpose in other ways.
