हे निश्चित आहे की ॲल्युमिनियम फॉइल स्वतःच एक चांगला इन्सुलेटर नाही, कारण ॲल्युमिनियम फॉइल वीज चालवू शकते.
ॲल्युमिनियम फॉइलमध्ये तुलनेने खराब इन्सुलेशन गुणधर्म आहेत. जरी काही प्रकरणांमध्ये ॲल्युमिनियम फॉइलमध्ये विशिष्ट इन्सुलेट गुणधर्म असतात, त्याचे इन्सुलेट गुणधर्म इतर इन्सुलेट सामग्रीइतके चांगले नाहीत. कारण सामान्य परिस्थितीत, 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 अॅल्युमिनियम फॉइल. साधारणतः बोलातांनी, the higher the purity of the aluminum foil, the better its electrical conductivity and the higher its conductivity. त्यामुळे, 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. साधारणतः बोलातांनी, 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.
खरं तर, aluminum is known for its excellent thermal conductivity because it conducts heat so well. तथापि, 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.
