Halogen heating tube: A tungsten filament is placed in a quartz shell, and the filament design and shell make the filament emit light within a spectrum range.
It is divided into civil and industrial use.
★The far-infrared heating tube uses a quartz glass tube processed by a special process.
It is equipped with carbon fiber and tungsten wire materials as the heating element
Because quartz glass can absorb almost all the radiation from the electric heating wire. All visible light and near-infrared light can be converted into far-infrared radiation.
The current industrial infrared heating tubes have basically eliminated the milky white quartz tubes. Because the material is relatively brittle,
it cannot form a very long milky white heating tube.
And the red color has a light-shielding effect, blocking its heat.
Because of its high tube wall temperature, it is only suitable for near-infrared heating.
★Infrared rays are one of the many invisible rays in the sun
Discovered by the British scientist Herschel in 2000, they are also called infrared thermal radiation
He decomposed the sunlight with a prism Open, thermometers were placed on various colored ribbons in an attempt to measure the heating effect of various colors of light.
It was found that the thermometer located outside the red light heated up the fastest.
Therefore, it is concluded that in the solar spectrum, there must be invisible light outside the red light, which is infrared. It can also be used as a transmission medium.
&The wavelength of infrared rays in the solar spectrum is larger than visible light, and the wavelength is.~&.
★Infrared rays can be divided into three parts, namely near infrared rays,
丶, wavelengths between (.)～(.)&
丶 mid-infrared rays, wavelengths between (.)～&
Far infrared rays have wavelengths between ~.
Infrared ray is an electromagnetic wave with a wavelength between microwaves and visible light
The wavelength is between nanometers and millimeters, and is an invisible light with a longer wavelength than red light
Covering the thermal radiation emitted by objects at room temperature band.
The ability to penetrate clouds and fog is stronger than visible light. It has a wide range of uses in communications, detection, medical treatment, military and other aspects.
