The microwave curing oven is mainly composed of curing chamber body, heating chamber and temperature control. The solid chamber has straight-through, channel, and bridge curing furnaces; the heating methods of the heating system include: diesel, gas (natural gas, liquefied gas), electric heating (far infrared, quartz tube), etc.

In the 1950s and 1960s, steam and coal or electric heating were mainly used as heat sources to achieve drying and curing. In the 1960s, infrared drying and quartz tubes appeared, far infrared drying and microwave drying appeared in the 1970s, and appeared in the 1990s. High-infrared rapid heating technology; with the requirements for drying temperature control and temperature control uniformity, hot air circulation in the furnace appeared. In the late 1980s, a fuel (gas) hot air circulation drying and curing furnace appeared, and The application of fuel (gas) hot air drying and curing is becoming more and more extensive; the method of using fuel (gas) heating to replace electric baking is a major energy-saving technology: in the case of high economic efficiency, the burner fuel hot air circulation type The heating drying and curing process has become the mainstream in the coating production line, and the hot air circulation drying room has the characteristics of uniform heating, small temperature difference between upper and lower, large adjustable range of drying temperature, and convenient use and maintenance.

Drying and curing equipment is relatively less problematic, but attention should still be paid to heat preservation, energy saving and safety!

1: The temperature of the external surface of the drying chamber is too high

The improper selection of the room body insulation materials is the main reason for the poor insulation effect, the surface temperature exceeding the standard, and the insulation performance not meeting the requirements, resulting in increased energy consumption!

Two: The exhaust gas discharge pipeline is set improperly or not set

The exhaust gas outlet of the drying and curing room of some painting lines is not connected to the outdoors, while in the workshop, the exhaust gas is directly discharged into the workshop, causing air pollution in the workshop; some painting lines have the exhaust gas outlet of the drying and curing room It is not set in a place with high exhaust gas concentration, which is not conducive to the rapid exhaust of exhaust gas and prevents accumulation. After spraying, the workpiece enters the drying and curing room. Because the coating contains organic solvents to varying degrees, organic solvent exhaust gas will be generated during the drying and curing process Exhaust gas is flammable. If the exhaust gas is not discharged from the drying room in time and accumulates in the drying room, once the concentration is too high, it will cause safety hazards and cause pollution to the environment!
