    Ceramic heater
    Ceramic heater is a high-efficiency heater with uniform thermal distribution, metal alloy with excellent thermal conductivity, which ensures uniform temperature of hot surface and eliminates hot and cold spots of equipment.
    There are two types of ceramic heaters, namely PTC ceramic heating element and MCH ceramic heating element. The materials used in these two products are completely different, but the finished products are similar to ceramics, so they are collectively referred to as "ceramic heating elements".

    Ceramic heaters have the advantages of long life, good thermal insulation performance, strong mechanical properties, corrosion resistance, and magnetic field resistance.

    Preparation method
    The alloy wire is cast in a semiconductor made of quartz glass. It has the characteristics of high temperature resistance (up to 1200 degrees), anti-corrosion, beautiful and wear-resistant. Widely used in aquarium fish tank heating, high temperature heating furnace, semiconductor engineering, glass, ceramics and wire engineering.

    Category by shape
    Ceramic electric heater
    There are ring and plate specifications, reliable operation, long life, sturdy and durable, energy saving, and has the advantages of flexible installation, high temperature resistance, fast heat transfer, good insulation, and production is not limited by model and size. According to the wiring method required by the user, the voltage is from 36V, 110V, 180V, 220V, 380V, and the power load is 6.5W per square. Compared with the traditional electric heater, the energy consumption can be reduced by 30%.

    Ceramic heater
    It is suitable for electric heating products such as electric splints, hair curlers, electric irons, electric irons, hair dryers, dryers, steamers, heaters, toilet seats with warm water, and medical equipment for straight hair. Ceramic heaters have the advantages of easy installation, high temperature resistance, fast heat transfer, good insulation, and production is not limited by models and specifications  .

    Category from material
    PTC ceramic heating element
    The PTC ceramic heating element is a thermistor, which is composed of a PTC ceramic heating element and an aluminum tube. It has the advantages of small thermal resistance and high heat exchange efficiency, and is an automatic constant temperature and power-saving electric heater.
    Structural principle: PTC ceramic heating element is a kind of positive temperature coefficient self-controlling ceramic heating element sintered at high temperature.
    Main advantages: The surface temperature of the PTC ceramic heating element can be automatically controlled and constant, which can prevent the phenomenon of dry burning
    Main disadvantages: 1. The surface of the PTC ceramic heating element itself is charged, and it needs to be installed in a special heat dissipation component after surface insulation treatment, which increases the assembly cost; 2. The product and the object to be heated are indirectly heated due to heat loss, which leads to a decrease in thermal efficiency; 3 . The heating power of the PTC ceramic heating element will gradually decay with the increase of working time; 4. The lead content of the product does not meet the environmental protection requirements.

    MCH ceramic heater
    MCH ceramic heating element uses alumina ceramic, which is a new type of high-efficiency, environment-friendly and energy-saving ceramic heating element. It has built-in heating wire. Compared with PTC ceramic heating element, it can save 20~30% electric energy under the same heating effect.
    Structural principle: A new type of heating element is formed by using alumina ceramics with high thermal conductivity as the matrix and heat-resistant and refractory metals as the internal electrodes to form a heating circuit.
    Main advantages: The surface of the product is not charged, and the water and electricity are isolated during the working process; the ceramic base material is not easy to form scale during use; the volume is small, and the power density (≥35w/cm²) heats up quickly (can reach more than 900 ℃ in 30 seconds), High thermal efficiency; good safety, the heating circuit is sealed in ceramics, the insulation withstand voltage is 4200V/S without breakdown, the product insulation resistance is ≥100MΩ; the service life is long, the average service life is ≥10000 hours; the product has good acid and alkali resistance; The medium power is stable, and the power will not be attenuated for long-term use; it does not contain harmful substances and meets the requirements of ROHS; the product can withstand dry burning.
    The main disadvantage: the production process is complicated and the cost is high
    Precautions for MCH heating element:
    Due to the fast heating speed, care should be taken to prevent burns
    In general, MCH ceramics are more environmentally friendly than PTC ceramics, have higher thermal efficiency, and have a longer service life, but cannot control the constant temperature automatically.

    Product Structure
    Product structure of ceramic heater: The ceramic heater is made of stainless steel skin, with a resistance wire inside the ceramic with high insulation and fire resistance, and then mechanically twisted into shape, connected to the power supply, and ready to use. Heating up to 500 degrees in 30 seconds

    *Power supply from 12V-380V any
    *The shape is not limited by the shape (can be customized)
    *Adopt foreign technology of honeycomb ceramic heater element
    *Not afraid of water and acid and alkali
    *It is heated by ceramic sheets, which does not emit red light, does not burn, and heats up quickly, and it can rise to 500 ℃ within 30 seconds.
    *500 ℃, the following nameless fire does not consume oxygen, does not oxidize, does not dry the mouth and tongue, can deodorize and keep indoor air fresh.
    *The thermal efficiency can reach more than 90%, which is 1.5 times that of PTC heaters, and 2 times that of traditional heating wire heaters, which can save 30% of energy and electricity expenses.
    * It can emit far infrared rays and radiant heat, and its radiation rate is as high as 91%.
    *It does not burst when exposed to water, acid and alkali resistant, suitable for use in harsh environments.
    *There is no inrush current when starting, and the temperature can be maintained at a constant temperature.
    *Ceramic heater is suitable for: make-up, face application, rheumatism, relief of joint pain. In addition to the warmth of the room, it also has excellent effects on cold feet, sore feet and so on when sitting in the office and practitioners.
    *Use any voltage from 12V-380V, and any power from 50W-2000W.
    * Widely used in household appliances (hair dryer), beauty equipment, medical equipment, industrial dryers, fax machines, etc.
