Infrared led heating
Infrared led Produce heating whether efficiently. Mainly depends on the absorption of the object. The absorption rate more than high , the better the effect of infrared radiation. The absorption rate depends on the type of heated material, the surface state, and the wave length of the infrared radiation source.The Reflectivity ratio is different when different surface conditions and different materials. Penetration with the nature and thickness of the material varies.Different materials have different effective penetration.Penetration of non-transparent material usually regarded as zero.in General metallic crystals are very dense,the electromagnetic radiation from the surface can rapidly decay in a very short distance,so heat radiation penetration depth on the metal is micrometer level.The molecular structure of the non-metallic material is not very dense,therefore, when the incident electromagnetic wave reaches the interface, electromagnetic wave is rarely reflected, easily pass and into the surface,When passing through the full thickness only,unabsorbed radiation energy can be pass.Therefore, the non metal’the penetration depth is high than metal.Superiority and efficiency of Infrared heating, the user accept infrared drying heating method in recent years(Infrared with the amazing speed of development), mainly advantages of infrared drying method has the following advantages:
1. With the penetrating power, and can produce heating both inside and outside.
2 Not need the heat transfer medium to passes, thermal efficiency is good. 3 can be localized heating, save energy.
4 To provide a comfortable working environment.
5 to save the construction cost and space, combination, installation and maintenance simple and easy.
6 heating process is clean.
7 temperature control is easy, and the temperature rise rapidly, and is relatively safe.
8 thermal inertia is small, do not need to preheat, save manpower.
Because infrared heating has the advantages and therefore to obtain high efficiency and uniformity of heating is possible and get high quality products
