Transfer magnesium oxide powder with good insulation and thermal conductivity to the surface of the metal in the electric heating tube

The heating of an electric heating tube is due to the presence of a resistance wire inside the tube. Once the resistance wire is energized, heat is generated and transmitted to the surface of the metal of the electric heating tube by magnesium oxide powder with good insulation and thermal conductivity. In this way, the surface of the electric heating tube will quickly heat up, which will play a heating role.

It is often said that electric heating tubes can heat because they have electric heating wires, which are generally divided into two types: iron chromium aluminum and nickel chromium alloy wires. There are some differences in price and material between these two types of electric heating wires.

Price: Iron chromium aluminum is affordable, and nickel chromium wire is more expensive than iron chromium aluminum.

Material: 1. The temperature of iron, chromium, and aluminum used in the atmosphere is high. The iron chromium aluminum electric heating wire 0Cr27AL7Mo2 has the highest temperature of up to 1400 ℃, while the nickel chromium wire Cr20Ni80 has the highest temperature of only 1200 ℃.

2. Under the same working temperature in the atmosphere, the lifespan of the iron chromium aluminum network is longer than that of nickel chromium alloy wire.

3. The antioxidant performance of nickel chromium wire is better than that of iron chromium wire.

2, What is the difference between an electric heating tube and an electric heating wire?

The difference between electric heating and electric heating is that the surface of electric heating is not charged, while the surface of electric heating is charged. Electric heating is used in a closed space because the surface of the electric heating is charged when it is electrified. Therefore, electric heating is usually used in environments such as electric heating, air, liquids, etc. The surface of the heating tube cannot conduct electricity because magnesium oxide powder is tightly filled between the heating wire and the shell of the heating tube. Electric heating is very similar to electric heating, and electric heating is the raw material for electric heating, so the cost of electric heating is lower than that of electric heating.
