Alyuminiy folga o'zi yaxshi izolyator emasligi aniq, chunki alyuminiy folga elektr tokini o'tkazishi mumkin.
Alyuminiy folga nisbatan zaif izolyatsiya xususiyatlariga ega. Alyuminiy folga ba'zi hollarda ma'lum izolyatsion xususiyatlarga ega bo'lsa-da, uning izolyatsion xususiyatlari boshqa izolyatsion materiallar kabi yaxshi emas. Chunki oddiy sharoitda, 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 alyuminiy folga. Umuman aytganda, the higher the purity of the aluminum foil, the better its electrical conductivity and the higher its conductivity. Shuning uchun, 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. Umuman aytganda, 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.
Aslida, aluminum is known for its excellent thermal conductivity because it conducts heat so well. Biroq, 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.
