Background

The Dacromet coating is a novel anticorrosive coating with zinc powder, aluminum powder, chromic acid and deionized water as main components, the thickness of the Dacromet coating is only 4-8 mu m, but the antirust effect of the Dacromet coating is 7-10 times of that of the traditional electrogalvanizing, hot galvanizing or coating method, red rust does not appear on standard parts and pipe fittings treated by the Dacromet process after a salt spray resistance test for more than 1200h, the Dacromet treatment process determines that the Dacromet does not have hydrogen embrittlement phenomenon, so the Dacromet is very suitable for coating stress parts, the Dacromet can resist high-temperature corrosion, the heat-resistant temperature can reach more than 300 ℃, the Dacromet coating has good bonding force with a metal matrix and strong adhesiveness with other additional coatings, the treated parts are easy to spray and color, the bonding force with an organic coating even exceeds that of a phosphating coating, and deep holes of workpieces due to electrostatic shielding effect, The parts such as the slit, the inner wall of the pipe fitting and the like are difficult to be electroplated with zinc, so the parts of the workpiece cannot be protected by an electroplating method, the dacromet can enter the parts of the workpiece to form a dacromet coating, and in the whole process of production processing and workpiece coating, the dacromet cannot generate waste water and waste gas which pollute the environment, does not need three-waste treatment, and reduces the treatment cost.

The Dacromet coating needs to be dried by using a drying device after the coating is finished, steam is generated in the drying process, and the steam accumulated in the drying device can influence the drying effect of the drying device on the Dacromet coating. We have therefore improved this and have proposed a drying apparatus for the application of a coating of dacromet.
