Judging the pros and cons of the ceramic heater surface

Judging the pros and cons of the ceramic heater surface

 

Surface average power density

The higher the average surface power density can be, the better the performance of the heater.

2. Limit temperature

The higher the ultimate temperature, the better the temperature resistance, so the longer the service life is at the same temperature, the higher the limit temperature, the better the heater performance.

3. Weight

Ceramic heaters of the same type generally have a higher mass and a higher heating efficiency.

4. Lifting temperature performance

The faster the temperature rises and falls, the better the heater performance.

5. Service life

The service life is an important indicator of the performance parameters of the heater. The longer the service life, the better the performance.

6. energy saving effect

Obviously, the better the energy saving effect, the better the performance of the heater.

7. Consistency

The higher the consistency of the parameters of the same type of heater (heat-lifting performance, weight, etc.), the better the performance of the heater.

Factors unrelated to heater performance

8. Glazed brightness

The first condition of the ceramic infrared heater is heating. Therefore, the higher the ceramic emissivity, the better the performance, the glaze brightness is independent of the emissivity, and the glaze is easily melted at high temperatures, so it is not the brighter heating. The better the device.

The nature of gasket fluid:

 

The viscosity of the liquid has a great influence on the sealing performance of the packing and gasket. The fluid with high viscosity is easy to seal due to its poor fluidity. The viscosity of liquid is much greater than that of gas, so liquid is easier to seal than gas. Saturated steam is easier to seal than superheated steam because it will condense droplets and block the leaking passage between the sealing surfaces. The larger the molecular volume of the fluid, the easier it is to be blocked by the narrow sealing gap, thus making it easier to seal. The wettability of the liquid to the seal material also has a certain effect on the seal. Liquids that are easy to infiltrate are prone to permeate leakage due to the capillary action of the micropores inside the gasket and filler.
