Electric heating performance
1 Power self-regulating performance The electric heating power of the heating cable is automatically reduced with increasing temperature, or automatically increased with decreasing temperature.
2 Self-limiting temperature performance When the electric heating cable is heated, the temperature rises and the resistance increases. When the resistance reaches a great value, the electric heating power tends to be extremely small and the temperature rises to the high limit. This is the self-limiting temperature of the electric heating cable. characteristic. Temperature-limited heat tracing refers to the process of heat tracing in a certain temperature zone below the high temperature limit.
3 PTC memory performance The electrical resistance of the heating cable increases with increasing temperature. If the resistance can return to the original starting point along the original heating route during cooling, it has the PTC memory performance. Long-term repeated use of electric heating cables with memory performance
Low temperature automatic temperature and electric heating cable working principle:
The pipeline insulation electric heating system is wound or tiled on the outside of the pipeline or tank by various ways of automatic temperature control and heat tracing, and the thermal insulation material is laid outside. One end of the automatic temperature control heating cable is connected with the temperature controller to accurately control the automatic control. When the temperature sensor detects that the temperature of the pipeline is lower than the set temperature, the thermostat is turned on and the automatic temperature control heating cable starts to run. When the temperature sensor detects that the pipeline temperature is higher than When the set temperature is reached, the thermostat is disconnected from the power supply, so that the self-controlled temperature-heating heating cable runs in the most economical and reasonable state and meets the medium's antifreeze and anti-blocking requirements.
The advantages of electric heating are:
The corresponding heating cable system is equipped with automatic adjustment of output power, so it will not be burned due to its own heat, but because of the actual need for heat compensation, it is a new generation of energy-saving constant temperature heaters. Low temperature quick start, uniform temperature, because each local adjustment may be auto-heating temperature is at. The installation is simple, the maintenance is simple, the automation level is high, and the operation and maintenance costs are low. Safe and reliable, wide use, no environmental pollution, long life.
Zirconium oxide ceramic offers much stronger mechanism strength, fracture toughness than other fine ceramic material, it is well suited to replacing metals due to its these exceptional features.Besides, zriconia has far highest resistance to chemicals and superior erosion resistance, This material is very fit to build wear parts ,cutting tools in every harsh environment.In the meantime, very low thermal conductivity is other critical characteristics of zirconia, it's a very ideal material in need of low thermal conductivity field.
Yttria partially stabilized zirconia(Y-TZP), Magnesia partially stabilized zirconia (M-PSZ) as two regular material exist there for variety of zirconia ceramic components' production.
Zirconia ceramic components typically works as structural ceramics, wear parts, cutting tools, precision valve seats and seals, pump pistons,pump sleeves, spray nozzles, ceramic bearings, fiber optical capillary, oxygen sensors and so on.
