In the coating production line, it is inevitable to equip a complete set of excellent drying and curing equipment, which mainly consists of a drying chamber body, a heating system, and temperature control. Because each part is carefully selected, the drying and curing equipment has relatively fewer problems in the coating process. Through practice, it has been proven that there is still room for improvement in the insulation, energy saving, and safety aspects of the drying and curing equipment in the coating production line. Therefore, it often presents the phenomenon of excessively high surface temperature outside the drying chamber. If we delve into the root cause, improper selection of insulation materials for the chamber is the main reason for poor insulation, surface temperature overruns, and inadequate insulation performance. This not only increases the energy consumption of the painting production line, but also does not comply with the relevant regulations on safety skills for drying rooms in the standards. As a drying room in the coating production line, not only should it have excellent insulation, but its outer wall surface temperature should not be higher than 15 ℃ above room temperature, otherwise it will cause adverse consequences. In addition, some coating production lines do not connect the exhaust pipe outlet of the drying and curing room to the outside, while in the workshop, the exhaust gas is directly discharged into the workshop, causing air pollution in the workshop. Some coating production lines' drying and curing rooms do not have exhaust gas discharge outlets located in areas with high exhaust gas concentrations, which is not conducive to the rapid discharge of exhaust gas and leads to simple accumulation. There are also clear regulations in this regard that the exhaust outlet of the drying room in the coating production line should be located in an area with a high concentration of combustible gases; Before entering the drying and solidification chamber, the sprayed workpiece should be dried in the sun to allow the organic solvents that have been applied to evaporate. It should be noted that organic solvent waste gas will occur during the drying and solidification process. Organic solvent waste gas is flammable, and if the waste gas is not discharged from the drying chamber in a timely manner and accumulates in the drying chamber, once the concentration is too high, it will form a safety hazard, which is very risky.
