*The heat treatment is 1 ~ 10 times faster than the general method, and the large radiation shortens the heating time. *Save about 30% ~ 50% of electricity. *The volume of the equipment can be reduced by more than half. *No open fire, high safety and durability. *The heated material is uniform. *Easy maintenance and replacement *No dust or harmful gas. *Simple operation and automatic control *Low cost and high efficiency The difference between infrared and far infrared; Infrared ray is a kind of energy wave, which belongs to a family of electromagnetic waves because some of them are electric waves and some are magnetic waves. In the electromagnetic spectrum of polarization analysis, infrared ray is a radiation wave between beyond the visible light band and the outside of microwave, which is an area invisible to the naked eye. Please refer to the following figure. The frequency of infrared ray is about 1012 to 5 × Between 1014c/s, the name of infrared ray and its effect depend on its wavelength. It is known from the infrared spectrum that its wavelength ranges from 0.75 to 1000 μ And is divided into far and near; the wavelength is usually 0.75 to 2.5 μ It is called near infrared, and 2.5 to 1000 μ It is called far infrared; in use, it is divided into three areas, namely, near infrared and intermediate infrared (2.5 μ~ five point six μ)、 And far infrared (2.5 μ~ 1,000 μ) However, in fact, in the field of various electromagnetic waves and rays, there is no precise boundary, but the two ends overlap each other
