Various classifications of bolt heaters

Bolt electric heaters are commonly used electric heating devices. It is small in size, high in heating power and widely used. Here is a detailed introduction to the types of bolt heaters, so that you can understand and choose correctly: according to the different materials, there are ceramic bolt electric heaters, stainless steel bolt electric heaters and so on. The shell of the ceramic bolt heater is made of stainless steel, and the heating resistance wire inside is added with heat-resistant ceramics. The advantage of this is that the ceramics can prevent corrosion, and the heater heats up quickly, has high efficiency, and does not pollute the environment when used, and is environmentally friendly Energy saving. The stainless steel bolt heater is evenly distributed with high-temperature resistance wires. The internal structure without fillers is filled with crystalline magnesium oxide powder. When the current passes through the resistance wires, the crystalline magnesium oxide powder is heated and floats outwards. At this time, it is in a high temperature state, and when it reaches the adherend, it will send heat to achieve the purpose of heating. In addition, there are also cast bolt electric heaters, braided heaters and so on. The former is heated in a solution such as copper and aluminum, which is very closely related to industry, while the latter uses multiple resistance wires to be wound and combined with the fiber body to generate heat. It is also widely used in industry. Bolt electric heaters are electrical related devices. If used improperly, it is easy to cause undesirable consequences. So I have listed some precautions for the use of bolt heaters: first use in an adapted environment, try to avoid high temperature and humidity , Corrosive environment; secondly, at the heater's power and rated current and voltage to prevent it from overloading and causing fire; the effective heating element of the bolt electric heater must all be immersed in the heated object to prevent it from burning; the bolt electric heater The wiring part of the cable should also be avoided to be exposed to the air; when the bolt electric heater is not in use, it should be placed in a dry and non-corrosive environment.
