Application features of silicon rubber heating chip
1. The heating plate using the electric heating device, it is necessary to pay attention to its continued use operating temperature should be less than 240 ℃, the instantaneous does not exceed 300 ℃.
2. The silica gel heating chip can work and bear pressure. Use auxiliary pressure plate to make it close to the hot surface. Outstanding thermal conductivity, temperature not to surpass 240 ℃ in the assignments section, the current density can be up to 3 w/c ㎡. We see a lot of shawl massagers, massage belts, backrest massagers and so on are made with non-woven fever piece. Non-woven fever piece only 3 to 5 mm, the thickness of the area from 10 cm to 4.0 ㎡, the work from 0.5 watts to several hundred watts, the highest working temperature of 150 ℃. It is an ideal heating element for the design of low temperature surface heating applications.
3. Zhang Tieshi device working conditions, to allow operating temperature is less than 150 ℃.
4. If the air dry condition, the data constraints of heat-resistant, its power density should be less than 1 W/c ㎡; Not continue working condition, the power density of 1.4 W/c ㎡.
5. The working voltage of the heating plate is selected according to the criteria of high power - high voltage and low power - low voltage. Special requirements can be listed out.
