Halogen lamp infrared plastic heating

Infrared heating technology is a new type of technology that has been widely used and has a very broad development prospect. At the same time, infrared heating technology is not only energy efficient, clean and environmentally friendly, but also can better ensure product quality. This paper discusses infrared heating technology in the plastics processing process.

As a new type of heating technology, infrared heating technology has incomparable advantages over traditional heating technology, including improved heating process, uniform heating of materials, high product quality, space saving, no pollution of the environment, etc. Due to the existence of these advantages, infrared heating technology has a very wide application prospect in the plastics processing industry.

Principle: Infrared heating technology is a drying method that uses infrared radiation elements to emit infrared rays that are absorbed by materials and directly converted into heat energy to achieve the purpose of heating and drying. The essence is the infrared radiation heat transfer process, infrared as a kind of electromagnetic wave, has a certain penetration, can transmit energy through radiation.

After the material absorbs the infrared radiation energy, the radiation energy will be completely transformed into the rotation energy of the material molecules or make the rotation energy of the molecules change. And the vibrational spectrum can increase the amplitude of the vibrational or rotational action of the material molecules, thus intensifying their internal vibration.

Due to the movement of electrons and molecules vibration speed is very fast, so the material between the lattice and the bond group vibration collision faster, friction heat faster, so that the material in the use of infrared heating to warm up faster. In particular, the infrared radiation frequency and the material molecules of the same inherent frequency, will produce similar resonance phenomenon, so the internal movement of the material molecules more intense, heating up faster, so as to achieve the purpose of rapid drying.

Due to the infrared ray has a certain penetration, infrared heating material internal heat accumulation, the temperature is constantly rising; material external due to the continuous evaporation of moisture heat absorption, the temperature is constantly reduced; material formed a temperature difference from inside to outside, so the material heat diffusion process from inside to outside. In addition, the internal moisture content of the material is greater than the external, and the moisture is diffused from the inside to the outside. Therefore, the wet diffusion and thermal diffusion of materials in the same direction, thus accelerating the diffusion of water, that is, to accelerate the drying process of materials.
