Overview
The YONGCHAOMT D10-YC004-L240mm Experimental Spreader Metering rod is a precision Spreader tool manufactured using an innovative process. It produces a specific wavy Linear dispersion on the surface of steel bars by cold extrusion technology, replacing the traditional way of winding steel wires. It is used for preparing wet-film coatings of precise Film thickness in experiments or small-scale production.
Features
1. Innovative process: Using cold extrusion processing technology, Linear dispersion is integrally formed on the surface of the steel rod, without traditional winding steel wire, which eliminates the risk of loosening or breaking of the steel wire.
2. Easy to clean: Linear dispersion on the surface is smooth and smooth, easy to clean thoroughly and easy to maintain.
3. High Abrasion Resistance: The surface is plated with a hard chromium layer with a hardness of up to 1300HV, which significantly improves the wear resistance performance and service life.
4. Precision and reliable: Specially designed for ultra-thin film Spreader, it can achieve the thin layer Spreader effect that is difficult to achieve with traditional bar, and the wet film thickness control is accurate.
Principle
The working principle of the Metering rod is based on its surface precision-machined concave-convex wavy Linear dispersion. As the rod rolls on the surface of the substrate, the grooves carry and transfer the Basis Weight paint, and the raised parts scrape off the excess paint to form a wet-film coating with uniform Film thickness corresponding to the depth of the grooves on the substrate. Its 4μm wet film thickness is determined by the specific groove depth.
Applications
Laboratory research and development, small batch trial production, coating performance testing, inks Spreader, Adhesive Spreader, functional coating prepative
Steps
1. Fix the substrate to be Spreader flat.
2. Take an appropriate amount of paint and place it at one end of the substrate or apply it directly in front of the Metering rod.
3. Holding both ends of the Metering rod, roll the rod body smoothly on the substrate at a uniform speed and appropriate pressure.
4. After Spreader is completed, clean the surface of Metering rod thoroughly with suitable solvent in time.
Notice
* Please make sure that the surface of Metering rod is clean, drying and free of damage before use.
* Maintain uniform speed and pressure stability during operation to ensure uniform film Film thickness.
* It should be cleaned immediately after use to avoid the paint drying up in the groove affecting the accuracy and next use.
* Use a soft cloth and suitable solvent when cleaning to avoid scratching hard chrome platings with hard objects.
* Store in a drying clean place to avoid bumping to protect delicate surfaces.
