Then the heating sheet for accessing multimeter and temperature measurer is put into circulating water chennel by surface, heating rate is 2 DEG C/min, records it
Variation of the resistance value from room temperature to curie point.
Fig. 4 is that resistance-temperature of heated at constant temperature piece obtained by 1-5 of the embodiment of the present invention tests test effect figure.Due to each heating sheet
The type of middle conducting particles and the difference of quantity, the resistance of each heating sheet is not also identical, and room temperature resistance range is in 260 Ω~600
Ω.Heating sheet is heated, resistance-temperature test curve figure is that is, low in heating sheet temperature as shown in figure 4, heating initial stage
When 45 DEG C, the resistance of embodiment 1-5 heated at constant temperature piece is held essentially constant；When heated at constant temperature piece is heated to Curie temperature 45
When near DEG C, several groups of materials all show apparent PTC effect, and each sheet resistance that heats increased dramatically, and are rapidly increased to tens
Europe becomes semiconductor or insulator, continue heating reach its Curie temperature highest point after, heating sheet resistance have certain decline
(there is weaker NTC effect), then tends towards stability.Increased dramatically for resistance can guarantee that circuit is because of resistance during the energization
It is sufficiently large, make heating power very little and circuit is made to stop heating, so that temperature control be made to avoid at 45 DEG C of Curie point or so
Because temperature it is excessively high caused by local scald.But since the type and ratio of crystalline polymer in each case study on implementation are different, PTC intensity
It is different.Wherein (sudden change of resistivity is big in circuit, and heating power is small, can disconnect electricity in time up to 5.3 for the PTC intensity of embodiment 5
Road preferably guarantees the control and precision of temperature), and its room temperature resistance is only 260 Ω, and heating sheet can be made to have at heating initial stage
Relatively high power realizes the stability for being rapidly heated and guaranteeing subsequent equilibrium temperature.
