  Dongguan City Electric Co., Ltd. is a Arima and fever tablets, heater, production and development as one of the manufacturers of electric products, the company produces a variety of heating element, the hotline. Ceramic heating element is just one of them, here to introduce you to what is a ceramic heating element.
 
  First, the ceramic heating element features:
 
  High temperature ceramic heat for baking (MCH) is directly on AL2O3 alumina ceramic green printed resistor paste after, at a high temperature of about 1600 ℃ for baking, and then by a new generation of electrode leads after treatment, the production of low temperature heating element. is the second alloy heating wire, and a new generation after the PTC heating elements are widely used in daily life, industrial and agricultural technology, telecommunications, health care, environmental protection and many other fields and other low-temperature heating needs. In terms of household electric appliances: such as a small warm air from warming, hair dryer, dryer, heater, air phones, dryers, electric plywood, electric irons, electric irons, straight hair, curly perm, electronic thermos in the electronics industry-specific terms such as small crystal devices thermostat;, cabinet, electric cooker, Commode ceramic heaters, water heaters, etc; in industries such as industrial drying technology equipment, electric bonding, a water heater, oil and acid-base liquid trough; in health care, such as infrared physiotherapy, intravenous fluid heater and so on.
 
  Second, the background information:
 
  With the advent of the era of integration of various electronic devices, electronic machine for circuit miniaturization, high density, versatility, reliability, speed and power of a higher demand because co-fired ceramic substrate able to meet many of the requirements for electronic machine circuit, so in recent years has been widely used. Co-fired ceramic substrate can be divided into high-temperature co-fired ceramic (HTCC) substrate and a low temperature co-fired ceramic (LTCC) substrate two kinds. High-temperature co-fired ceramic LTCC compared with high mechanical strength, high wiring density, chemical stability, high thermal coefficient and low cost materials, higher thermal stability requirements, require less volatile gas temperature, require higher heat sealing and packaging areas, has been more widely used. HTCC ceramic heat primarily to replace now the most widely used alloy wire heating element and the PTC heating element and its components. The existence of high-temperature alloy wire heating element is easily oxidized, short life, there is fire safe, low thermal efficiency, uneven heating and other shortcomings; PTC heating element and the heating temperature is generally only about 200 ℃, the heating temperature is higher than 120 ℃ of the commonly used four lead oxide, which are due to the large genus of leaded products being eliminated.
 
  Third, the ceramic heat advantages:
 
  A 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 saving;
 
  6, no fire, the use of safety;
 
  7, long life, reducing power failure;
 
  8, a heating body and air insulation, element acid and other corrosive substances;
 
  Fourth, the main raw material:
 
  1, the board: 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. Resistance: tungsten and other high-temperature materials
 
  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, an aging test: applying 110% of rated voltage in series with a diode-off three minutes for a cycle, a total of two cycles without exception.
 
  3, the voltage boost test: each with 130VAC, 250VAC voltage in series with a diode, powered heating element at each voltage without exception within 10 seconds. [Applicable to 230VAC fever tablets]
 
  4, thermal testing: Under normal voltage, electric substrate heat evenly, without exception.
 
  5, the physical properties of
 
  Density ≥3.6g / cm3
 
  Flexural strength ≥260MPa
 
  6. Lead Rally: axis of not less than 5Kgf, and the angle between the direction of the axis of not less than 45 3Kgf.
 
  7, the temperature performance:
 
  Operating temperature 100 ~ 230 ℃: maximum temperature up to 500 ~ 700 ℃.
 
  8, heating efficiency: 30 seconds up to operating temperature.
 
  9. Reliability: Installed after the opening 30 minutes, 30 minutes off the table for a loop, loop 1000 after the test without exception.
 
  Appearance:
 
  Look no mechanical damage burrs, cracks, corrosion, contamination, it is no more than warp 0.005mm / mm.
