What should be noted when using silicone rubber heaters?

Silicone rubber heater, as a commonly used electric heating element in research, mainly converts electrical energy into thermal energy. It can be widely used in various electric heating equipment of enterprises or can be used separately. The heating element of a 3D printer is stacked layer by layer to create a 3D model. Its operation process is similar to that of a traditional printer, except that traditional printers print ink onto paper to form a two-dimensional flat drawing, while 3D printers use liquid photosensitive resin materials, molten plastic fibers, gypsum powder and other materials to achieve layer by layer stacking and forming a 3D solid through spraying adhesives or extrusion. In recent years, due to the greenhouse effect, the temperature of the cabinet dehumidifier heater has been increasing year by year, and the atmospheric environmental factors have gradually deteriorated, such as high temperature, high humidity and other variable climates, making the threat to indoor power distribution facilities increasingly apparent. Silicone rubber heating belt is a particularly soft heating belt composed of nickel chromium alloy wire and insulation material. Its design has high power density, fast heating, high thermal efficiency, and long service life. In addition to being used for heat tracing and insulation in general constant power bands, it can also be used in places that require heating in some cases.

According to reports, when using silicone rubber heaters alone, leakage often occurs or the service life is shortened.

1. Silicone rubber heater is used to heat easily melted metals or solid nitrominerals, paraffin, asphalt and other substances. Firstly, the heating material is melted, and at this time, the external voltage of the silicone rubber heater can be reduced. After melting is completed, it can be restored to the rated voltage. In addition, when silicone rubber heaters heat nitrates and other explosive substances, safety measures should be fully considered.

When using a silicone rubber heater for air heating, attention should be paid to the uniform arrangement of the silicone rubber heater. The benefit of doing this is to ensure that the silicone rubber heater has sufficient and uniform heat dissipation space, and to ensure air flow as much as possible, thereby improving the heating efficiency of the silicone rubber heater.

The magnesium oxide at the outlet of the silicone rubber heater is easily contaminated by impurities and water infiltration. Therefore, attention should be paid to the condition of the outlet of the silicone rubber heater during operation to avoid leakage accidents.

4. The storage location of silicone rubber heaters must be kept dry and have appropriate insulation resistance. If the insulation resistance of the storage environment of the silicone rubber heater is found to be too low during use, it can be restored after low-voltage power on. The silicone rubber heater should be properly fixed before use, and the wiring part should be placed outside the insulation layer to avoid contact with corrosive, explosive media, and water.

5. When using silicone rubber heaters to control the heating of liquid or metal industrial solid materials, it should be noted that the silicone rubber heater can be completely inserted into the heated object, and students are not allowed to experience empty burning of the silicone rubber heater. If there are scale or carbon deposits on the outer metal shell of the silicone rubber heater after use, enterprises should analyze and remove them in a timely manner to avoid serious impacts on the cooling system performance and service network life of the silicone rubber heater.
