آیا فویل آلومینیومی عایق خوبی است؟?

مسلم است که فویل آلومینیومی خود عایق خوبی نیست, زیرا فویل آلومینیومی می تواند الکتریسیته را هدایت کند.

فویل آلومینیومی خواص عایق نسبتا ضعیفی دارد. اگرچه فویل آلومینیوم در برخی موارد دارای خواص عایق خاصی است, خواص عایق آن به خوبی سایر مواد عایق نیست. زیرا در شرایط عادی, 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 ورقه ی آلومینیومی. به طور کلی, the higher the purity of the aluminum foil, the better its electrical conductivity and the higher its conductivity. از این رو, در کاربردهای عملی, 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. به طور کلی, 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.

در حقیقت, aluminum is known for its excellent thermal conductivity because it conducts heat so well. با این حال, 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.
