Infrared radiation temperature control method for spraying production line

Abstract

The invention discloses an infrared radiation temperature control method for a spraying production line, a plurality of catalytic heating plates are arranged in an infrared radiation furnace, any catalytic heating plate is provided with a temperature sensor, and the infrared radiation temperature control method comprises the following steps of: simulation temperature detection, contrast temperature recording, fine adjustment, synchronous temperature rise adjustment, calculation of the temperature regulation coefficient of each catalytic heating plate, catalytic heating plate fine-tuning reference selection, and temperature control. According to the method, temperature control correlation and real-time temperature monitoring of the catalytic heating plates can be achieved, overall temperature control adjustment is carried out through the correlation coefficient, the individual difference of the catalytic heating plates and the furnace chamber temperature difference adjustment requirements are met, the product is heated uniformly and stably, the curing stability of the product is improved, and the qualified rate of the product is greatly improved. And a reflectivity attenuation self-adaptive adjusting function is realized, so that the temperature of the furnace chamber is stable and uniform, the curing temperature is stable, and the phenomena of non-uniform curing and incomplete curing are prevented.

Description

technical field [0001] The invention relates to an infrared radiation temperature control method, and belongs to the technical field of paint curing control methods. Background technique [0002] Infrared rays are also called infrared light. In the electromagnetic spectrum, electromagnetic radiation with wavelengths between red light and microwaves. Outside the range of visible light, the wavelength is longer than red light, which has a significant thermal effect. Infrared drying technology uses its unique thermal effect. Infrared rays are easily absorbed by objects and have radiation, penetrating power, and electromagnetic waves have special affinity for polar substances, such as water molecules. The required heat energy acts simultaneously inside and outside, which is more effective and thoroughly removes the bound water in the material, so as to achieve a more ideal drying effect, thereby avoiding the energy loss caused by heating the heat transfer medium, which is ben...
