Under what different circumstances will silicone rubber heaters increase heating time and slow down heating

In the use of civil and industrial silicone rubber heaters, there is often a problem of long heating time for the heating tube. The silicone rubber heater is mainly composed of nickel chromium alloy heating wire and silicone rubber high-temperature insulation layer. The high-temperature insulation layer of silicone rubber is a thin sheet (with a standard thickness of 1.5mm) composed of silicone rubber and glass fiber cloth, and the silicone rubber heater has good flexibility. Silicon rubber heating plate heating element: Wrap nickel alloy heating wire around glass fiber, heating power can reach 2.1W/c ㎡, heating more evenly. Moisture and chemical resistant silicone rubber material provides a longer heater lifespan. Pressure sensitive adhesive can be used to bond flat and smooth workpieces. Lithium battery heaters have basic functions, such as heating, constant temperature, and temperature control.

In the case of hot water supply, due to water quality issues, the surface of the heating tube is prone to scaling, and a large amount of scaling can lead to a decrease in the thermal efficiency of the heating tube. Therefore, in the case of hot water supply, if it is found that the heating of the silicone rubber heater is slow after a period of time, scaling should be considered first.

Generally speaking, the heating time is directly proportional to the power of the silicone rubber heater. The higher the power, the shorter the heating time. Therefore, a suitable power source should be selected before using a silicone rubber heater.

Figure 3. When designing a silicone rubber heater, consideration should be given to changes in the heating environment, whether it is heating the liquid or dry burning, because the heating environment cannot be completely uniform, so the heating time will increase or decrease with changes in the starting temperature. Therefore, when designing silicone rubber heaters, heating time should be considered, and the power should be appropriately high to ensure heating efficiency.

4. The external power supply environment can also affect the heating efficiency, and the corresponding silicone rubber heaters are different in voltage environments of 220V and 380V. Insufficient power supply voltage caused by peak electricity consumption or other reasons will cause the heating tubes to work at low power, and the heating efficiency will also decrease.

5. In addition, prolonged and uninterrupted use can also cause the heating of silicone rubber heaters to slow down, because the heating technology principle of most of our heating tubes is to internally control the resistance wire to generate heat and then transfer heat. Under long-term high temperature conditions, the resistance value of the resistance wire will increase, leading to different types of heating slowing down. Therefore, under long-term high temperature conditions, slowing down is a normal social phenomenon for oneself. It is possible to design and adopt a method of regular rest and maintenance, which not only ensures the heating efficiency of the system but also extends the lifespan of the network.
