Spiral-Type Wire Wound Rod

A spiral wire rod is a coating tool with helical grooves engraved on its surface, used to control the thickness of coatings. The principle is that the grooves hold the coating, and excess coating is scraped off during application, forming a uniform wet film. Its function is to simulate the coating process in laboratory or small-scale production settings, testing the leveling and hiding power of coatings. It is applied in quality control in the ink and coating industries, such as for paper and plastic film coating tests.
Selection
When selecting a spiral wire rod, the wire diameter should be considered, as it determines the wet film thickness. The choice should match the coating viscosity, with larger wire diameters selected for higher viscosities. The type of substrate also influences the selection, with finer wire diameters used for smooth surfaces. Standard specifications ensure comparability of results. Stainless steel is commonly used for its corrosion resistance. Ease of operation makes it suitable for routine testing.
