Why does the surface of the finned tubular heater turn black?
The finned tubular heater manufacturer will answer for you what is the reason for the blackening of the tubular heater surface?
1. Because the tubular heater itself has been damaged, the surface layer will turn black. If this is the case, the product does not have to be used again, and it is recommended to replace the tubular heater with a new one.
2. Caused by abnormal power supply system or frequent power cut off. The electric tubular heater in the application is constantly cut off or the power supply system is abnormal, which endangers all normal applications and turns black.
3. The point contact of the control panel is loose, the power cord plug and the electric heating power socket are loose.
4. The oxidation of the air by the electric heater. After the application of the electric tubular heater electric heater, due to the hazard of the gas or the damp and cold natural environment, the surface layer forms several gray-black blocks due to the oxidation of the air, which is like a stainless steel plate. When the flame burns, its surface becomes gray-black chemical substances. This kind of thing is more common, and this kind of gray-black metal oxide is non-toxic, and the electric tubular heater can be used again.
Therefore, when the electric tubular heater is heated for a period of time, the surface will deteriorate, and people should distinguish what caused it. If it also has a resistance value, it still shows that it is only caused by air oxidation; if it does not have a resistance value, it should be burned.
