How much do you know about the structure of coatings? Let's follow the editor of Metal coating from China to have a brief understanding of it!

The uniform coating structure includes a hollow roller and a rotating shaft arranged at the axis of the hollow roller, the rotating shaft is driven to rotate by a driving device, and an arc-shaped shaping sheet is surrounded on the body of the hollow roller. The space between the shaping sheet and the barrel of the hollow roller forms arc-shaped gaps at equal intervals, the entrance of the arc-shaped gap is provided with a coating extrusion nozzle, and the outlet of the arc-shaped gap is provided with a scraper. The blade of the scraper is tangent to the body of the hollow roller, the back of the scraper forms two scrapers, and the two scrapers are arranged above the textile to be processed to form a tool for extrusion coating. The layer forms a coating with a uniform thickness in the arc-shaped gap, peels off the hollow roller under the action of the scraper, and fits the textile under the action of the two scrapers, so that the thickness of the textile coating is consistent.
The above is a brief introduction to the structural knowledge of coatings from Metal coating from China.
