1, simple structure;


2, rapid heating, rapid temperature compensation;


3, the power density;


4, the heating temperature is high, up to 500 ℃;


5, high thermal efficiency, uniform heating, energy conservation;


6, no fire, safe to use;


7, long life, power failure to reduce;


8, the heating element and air-insulated, component acid and other corrosive substances;


Fourth, the main raw material:


1, substrate: with white alumina ceramic multilayer, а-Al2O3 content of not less than 95%


2, lead: the Ф0.48mm nickel wire.


3, casing, tape: Teflon, high temperature adhesive tape


4, the resistance: high-temperature materials such as tungsten


Fifth, the main properties:


1, the electrical properties


Insulation resistance: R≥5 × 108Ω [500VDC]


Rated applied voltage: 220VAC / 110VAC


Resistance: R + 10% (23 + 1 ℃) or according to user requirements of the contract.


2, aging test: applying 110% of the rated voltage in series with a diode-off three minutes of a cycle, a total of two cycles without exception.


3, the voltage boost test: each with 130VAC, 250VAC voltage, in series with a diode, a heating element is energized at each voltage without exception within 10 seconds. [For 230VAC heating sheet]


4, thermal testing: Under normal voltage, an electric substrate heat evenly, without exception.


5, the physical properties of


Density ≥3.6g / cm3


Flexural strength ≥260MPa


6. Lead Rally: axial direction is not less than 5Kgf, and the angle between the direction of the axis 45 is not less than 3Kgf.


7, the temperature performance:


Operating temperature 100 ~ 230 ℃: the maximum temperature of 500 ~ 700 ℃.


8, heating efficiency: up to operating temperature within 30 seconds.


9 Reliability: Installed after the opening 30 minutes, 30 minutes off the table as a loop, the loop 1000 after the test without exception.


Exterior:


Look no mechanical damage burr, cracks, corrosion, pollution, warpage of not more than 0.005mm / mm.
