Overview
YONGCHAOMT D10-YC060-L240mm Experimental Spreader Metering rod is a precision Spreader tool manufactured by cold extrusion technology. It achieves Spreader through concave-convex wavy Linear dispersion machined on the surface of the steel rod, replacing the bar of traditional winding steel wire, solving the problem that the steel wire is easy to loosen and difficult to clean, and has excellent Abrasion Resistance and service life.
Features
1. Using cold extrusion processing technology, Linear dispersion is integrally formed on the surface of the steel rod, without wire-wound, eliminating the risk of loosening or breaking of the steel wire.
2. Linear dispersion is smooth and easy to clean thoroughly.
3. The surface is plated with high hardness (1300HV) hard chrome platings, Abrasion Resistance is excellent, long service life.
4. The rod body is made of 304 stainless steel, making it a sturdy and durable structure.
Principle
The Metering rod uses a specific concave-convex wavy Linear dispersion (corresponding to 60 μm wet film thickness) precisely machined on its surface by cold extrusion technology to transfer and control the Spreader liquid. As the rod rolls on the surface of the substrate, the groove Basis Weight carries the Spreader liquid, and the raised part scrapes off the excess liquid to form a uniform wet-film with accurate Film thickness on the substrate.
Applications
Laboratory Spreaders, Sample prepatives, Paint Development, inks Testing, Adhesive Spreaders
Steps
1. Pour or drop the liquid to be Spreader onto one end of the substrate.
2. Place the grooved side of the Metering rod facing the liquid.
3. Pressure evenly with your hands and push the Metering rod to the other end at a constant speed to spread the liquid evenly.
4. Lift Metering rod to complete Single Spreader.
Notice
• Please clean the rod body thoroughly in time before and after use to prevent the residue from clogging the groove after drying.
• When cleaning, it is recommended to use suitable solvents and soft cloths to avoid scratching and damaging the chrome-plated surface with hard objects.
• Keep the pushing speed uniform and pressure stable during operation to ensure film Film thickness conformity.
• Do not use the Metering rod for viscous liquids or materials containing hard particles beyond its design range to avoid damaging the groove.
Store in a drying place to avoid bumping to maintain the integrity of its delicate structure.
