Rapid heating: microwave heating is completely different from traditional heating. Microwave heating is the direct absorption of microwaves by the object itself, and does not require a heat transfer process. Even materials with poor thermal conductivity can reach the required heating temperature in a very short time.
Efficient and energy-saving: there is no external loss during heat conduction and heat radiation, and the absorbed energy is mostly inside the heating element, so the thermal efficiency is high and can reach more than 80%. If the relevant thermal insulation configuration is applied to the heater, not only the thermal efficiency is increased, but also the environmental temperature is avoided, and the working conditions are improved. Microwave heating saves more than half of energy by far infrared heating.
Safe and hygienic, less environmental pollution: Microwave energy is controlled in the heating cavity and waveguide processed by metal materials, effectively preventing microwave leakage, no radiation hazard and harmful gas emissions, no thermal inertia and dust pollution.
Strong penetrating power and uniform heating: microwave energy can penetrate the corresponding depth to the medium. The longer the microwave wavelength, the deeper the penetration depth. The microwave allows the electromagnetic wave to uniformly penetrate the electromagnetic wave at the same time to generate thermal energy, which is not limited by the shape of the object, and can achieve uniform heating regardless of the shape of each part of the object.
The operation is simple, the adjustment is sensitive, and the control is convenient: the microwave heating can conveniently control the temperature of the heated body through the adjustment of the power output power, so that the automatic control can be accurately realized, and the application process and the PLC can be used for the heating process and the heating process specification. Programming control automated control of the production line.
Microwave-treated workpieces have higher density, hardness and toughness than conventional sintered workpieces. Sintering in a short time produces a uniform fine-grained microwave structure with large internal pores and a shape of pores that is better than conventional sintered circles, thus having better ductility and toughness. It is suitable for metal, non-metal oxide, ceramic sintering and inorganic Rapid and efficient sintering and synthesis of powders.
