The role of magnesium powder in electric heating tubes
The role of magnesium powder in electric heating pipes is often easily overlooked. Beste tells everyone here that the irregular filling of magnesium powder will cause the electric heating pipe to appear unstable during use. Therefore, the filling of magnesium powder in the production process has a necessary relationship with the quality of the electric heating tube. Here are three aspects that Beste noticed during the production process.
The first is whether the manufacturer (magnesium powder) is matched according to this ratio. The actual use of the inspection data basically has the problem that the coarse sand and fine sand seriously exceed the standard.
The second is that during the long-distance transportation of this electric heating pipe product, there will be sieving of sand particles with different mesh sizes. If it is directly re-used into the powder bin without remixing before use, the flow rate cannot be guaranteed;
The third is that the filling machine must cause the silt of the silo to be sieved during the shaking process, so why the same tube has a large difference in filling weight during operation because of the above three factors, of course, the factors affecting the flow rate are divided by the number of mesh In addition to the ratio, the viscosity of the moisture-proofing agent also has a considerable impact on the flow rate, which is also a detail that the magnesium powder plant must pay attention to in real time.
Therefore, it is also important to choose the appropriate magnesium powder for addition. I hope that everyone pays attention to the addition of magnesium powder when purchasing electric heating pipes. At this time, it is especially important to choose a regular manufacturer. Don't be more tempted by small and cheap. Big unnecessary loss.
When the electric heating pipe is used to heat easily meltable metals or solid nitrates, paraffin, asphalt and other substances, the heating substance must be melted first. At this time, the external voltage of the electric heating pipe can be reduced, and the melting voltage can be restored to the rated voltage. In addition, safety measures should be fully considered when heating the heating pipe with substances that are liable to explode, such as nitrate.
When the electric heating pipe is used for air heating, pay attention to the uniform arrangement of the electric heating pipe. The advantage of doing so is to ensure that the electric heating pipe has sufficient and uniform heat dissipation space, and to ensure the air mobility as much as possible, and improve the heating efficiency of the electric heating pipe.
The gap inside the electric heating tube is filled with magnesia. The magnesia at the outlet end of the heating tube is easily contaminated by the infiltration of impurities and moisture. Therefore, pay attention to the state of the outlet end of the heating tube during operation to avoid leakage accidents.
