क्या आप जानते हैं एल्युमिनियम फॉयल एक अच्छा इंसुलेटर है?

क्या एल्युमीनियम फ़ॉइल एक अच्छा इन्सुलेटर है??

यह निश्चित है कि एल्युमीनियम फ़ॉइल स्वयं एक अच्छा इन्सुलेटर नहीं है, क्योंकि एल्युमिनियम फॉयल बिजली का संचालन कर सकता है.

एल्युमीनियम फ़ॉइल में अपेक्षाकृत ख़राब इन्सुलेशन गुण होते हैं. हालाँकि कुछ मामलों में एल्यूमीनियम फ़ॉइल में कुछ इन्सुलेशन गुण होते हैं, इसके इन्सुलेशन गुण अन्य इन्सुलेशन सामग्री जितने अच्छे नहीं हैं. क्योंकि सामान्य परिस्थितियों में, 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 एल्यूमीनियम पन्नी. आम तौर पर बोलना, the higher the purity of the aluminum foil, the better its electrical conductivity and the higher its conductivity. इसलिए, व्यावहारिक अनुप्रयोगों में, 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. आम तौर पर बोलना, 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.

असल में, 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.
