How to improve the efficiency of infrared heating lamps?
1. Choose the appropriate wavelength. The working principle of the infrared heating tube, when the wavelength of the infrared radiated by the heating tube is consistent with the wavelength absorbed by the heated material, the heated object can absorb a large amount of infrared, causing the molecules and atoms inside the object to resonate, and the temperature of the object rises. To achieve the purpose of heating", based on this point, the first step in purchasing a heating tube is to choose an infrared tube that matches the wavelength of the heated material. For example, polyethylene and polyvinyl chloride plastics are particularly good infrared radiation absorbers in the mid-wave region.
2. Use proper coating. When the direction of the object to be heated is fixed, the coating can help the heating tube to conduct the light source energy radiated by it, focusing on the direction of the object to be heated, saving unnecessary heat loss and realizing effective work. The coating can be made into different coverage areas and angles.
There are two types of coatings, gold-plated reflective coating and white-plated reflective coating. The appropriate coating can be selected according to the following data:
Reflectivity: 90% gold-plated coating, 70% white coating.
Temperature resistance point: The recommended working environment temperature of the gold-plated coating is lower than 600 degrees, and the white-plated coating can be used at a high temperature of 900-1000 degrees.
