Line cloth Rod

The wire-wound rod is a coating tool that forms a wet film on a substrate by using a steel rod wrapped with metal wire. Its principle involves the grooves formed by the wire carrying a fixed amount of coating material when the rod rotates, which serves to control the thickness of the coating. It is used in laboratory coating processes such as ink opacity testing and paper sizing degree detection.
Selection
When selecting a wire-wound rod, the wire diameter corresponding to the coating thickness should be considered, with common specifications ranging from 10 μm to 200 μm. The rod length should be determined based on the testing standards, with conventional lengths ranging from 200 mm to 400 mm. Stainless steel material is suitable for most solvent-based coatings, while chrome-plated material should be used for corrosive liquids. The straightness error of the rod should be less than 0.1 mm, and the wire winding should be uniform without gaps.
