How do silicone rubber heating tapes work in silicone rubber heaters?

Silicone rubber heaters are mainly composed of metal tubes, insulating magnesium oxide powder and silicone rubber heating belts. So how does the silicone rubber heating zone work in silicone rubber heaters?

1. Working principle of silicone rubber heating strips

The working principle of silicone rubber heating belts is the same as other metal heating elements, which is the electric heating phenomenon after the metal is energized. Electric vehicle battery heaters use the heat energy generated by auxiliary heaters to heat the battery pack, which will not consume battery power, so it will not affect the power and range of electric vehicles. At the same time, it can also ensure the heat required by the air-conditioning system. The vehicle controller distributes heat by controlling the opening of each electric control valve, and the control method is simple. Cabinet dehumidification heaters In recent years, due to the greenhouse effect, the temperature has risen year by year, and the atmospheric environmental factors have gradually deteriorated. The changeable climate such as high temperature and high humidity has made the threats faced by indoor power distribution facilities more and more obvious. The oil drum heating belt adopts the soft and bendable characteristics of the silicone heating plate. The metal buckles are riveted on the reserved holes on both sides of the heating plate, and the spring buckles are buckled on the barrel, pipe, and tank. Easy and quick installation. The silicone rubber heating plate can be made to be tightly attached to the heated part by the tension of the spring, and the heating is rapid and the thermal efficiency is high. Electric heating means that after the current passes through the conductor, a certain amount of heat will be generated and conducted away by the conductor. The silicone rubber heating belt itself is a metal conductor, which can generate heat and provide heat energy after being energized.

2. Classification of types of silicone rubber heating belts

The types of silicone rubber heating belts are divided according to the chemical element content and organizational structure of the silicone rubber heating belts. The types of silicone rubber heating belts are iron-chromium-aluminum rubber plus tropical belts and nickel-chromium silicone rubber heating belts. These two types of silicone rubber and tropical belts have different functional characteristics as electric heating elements.

3. Advantages and disadvantages of iron-chromium-aluminum alloy silicone rubber heating belts

The advantage of iron-chromium-aluminum alloy silicone rubber heating belts is high working temperature. The highest working temperature of iron-chromium-aluminum alloy silicone rubber heating belts can reach 1400℃. Iron-chromium-aluminum alloy silicone rubber heating belts have long service life, high resistivity, good surface compositeness and good oxidation resistance.

The disadvantage of iron-chromium-aluminum alloy silicone rubber heating belts is low strength under high temperature environment. The plasticity of the iron-chromium-aluminum alloy silicone rubber heating belt increases with the increase of temperature, that is, the iron-chromium-aluminum alloy silicone rubber heating belt is easy to deform at high temperature and difficult to repair after deformation.

4. Advantages and disadvantages of nickel-chromium alloy silicone rubber heating belt

The advantages of nickel-chromium alloy silicone rubber heating belt are high strength in high temperature working environment, long-term high temperature operation, and it is not easy to deform and change the social structure. The room temperature plasticity of nickel-chromium alloy silicone rubber heating belt is good, and the repair technology after deformation is relatively simple. In addition, the nickel-chromium alloy silicone rubber heating belt has high emissivity, no magnetism, good corrosion resistance and ability, and long service life.

The disadvantage of the nickel-chromium alloy silicone rubber heating zone is that the working temperature does not reach the level of the previous silicone rubber heating zone.
