6. Performance characteristics:

1. High energy utilization rate: this equipment adopts microwave/electric hybrid heating, which can well integrate the traditional kiln and microwave heating It can save more than 40% energy than conventional electric kiln, gas kiln or oil kiln;

2. Good product quality: this equipment is based on the microwave heating mechanism, which is different from the conventional heating method. It is the internal friction of materials and the direct coupling of molecules caused by the movement of polar particles and forced vibration. The material body directly acts as the heating body. The product is heated evenly, and the product quality is good;

3. High production efficiency: this equipment can overcome the shortcomings of slow heating speed caused by the poor microwave absorption ability of some materials to be burned at low temperature during pure microwave heating, and extend the heating time of materials. At the same time, it makes full use of the advantages of microwave heating, and has high production efficiency;

4. Flexible process adjustment: It has the functions of gas replacement and atmosphere control, and can pass through protective gas, weak reducing gas, air, and oxygen enriched air; It can be used for high-temperature synthesis, sintering, ashing, incineration and heat treatment of various solid materials in various atmospheres (air, oxygen, nitrogen, argon, weak reducing atmosphere, etc.);

5. No environmental pollution: this equipment has no waste gas, sewage, dust, noise, etc., and uses a safe and reliable microwave shielding chamber and airtight system design to prevent microwave and gas leakage;

6. Small floor area of equipment: the floor area of this equipment is 1/2 of that of ordinary electric kiln, greatly reducing the land use cost;

7. Strong operability and convenient use: this equipment adopts PLC+touch screen control mode, which can directly exchange data with the computer. It can visualize the operation of the whole equipment on the computer, realize automatic data recording, access and supporting editing and printing functions, set multiple temperature curves, and have dual functions of automatic and manual operation;

8. Safe and reliable: this equipment is equipped with an industrial water-cooled microwave source system, which can be used 24 hours without interruption. The microwave leakage value of the equipment system is far lower than the national standard (only equivalent to the radiation level when using mobile phones). It has its own microwave leak prevention alarm device and safety lock. When the microwave exceeds the standard, the microwave source can be cut off automatically or manually, and the original technology is adopted, Isolate the microwave field from the electric heating to eliminate the influence of the microwave field on the electric heating components. The feeding and discharging devices are electrically controlled and self-locking to ensure the safety of the operator and equipment.
