Overview
The YONGCHAOMT D10-YC120-L240mm Experimental Spreader Metering rod is a precision Spreader tool manufactured using an innovative process. It uses cold extrusion technology to process a specific Linear dispersion on the surface of the steel rod to replace the traditional way of winding the steel wire, achieving a more stable and durable Spreader effect. It is suitable for precise Spreader operations in laboratories and small-scale production.
Features
1. Using cold extrusion processing technology, Linear dispersion is integrally formed on the surface of the steel rod to replace the traditional winding steel wire and completely eliminate the risk of loosening or breaking of the steel wire.
2. Linear dispersion on the surface is smooth and smooth, easy to clean thoroughly, and avoid sample residue.
3. The surface is plated with a hard chromium layer of high hardness (1300HV), which significantly improves Abrasion Resistance and service life.
4. It can achieve a more uniform and stable Spreader, which is especially conducive to the application of ultra-thin film Spreaders.
Principle
The Metering rod is used to Basis Weight Transfer and Spreader Liquids by means of a concave-convex wavy Linear dispersion precisely machined on its surface. As the rod rolls on the surface of the substrate, the Linear dispersion groove holds and carries a specific volume of paint, and the excess paint is scraped off, resulting in a wet-film coating of uniform Film thickness on the substrate, determined by the groove depth (here 120 μm wet film thickness).
Applications
Laboratory Development, Small Batch Sample Preparative, Coating inks Testing, Adhesive Spreader, Functional Film Production
Steps
1. Pour or drop the liquid to be Spreader onto one end of the substrate.
2. Linear dispersion end of the Metering rod is placed behind the liquid to ensure that the rod body is in parallel contact with the substrate surface.
3. Use your hands to apply even pressure and smoothly push or pull the Metering rod to roll over the entire Spreader area.
4. After the Spreader is completed, immediately clean the surface of the Metering rod with a suitable solvent and dry it for storage.
Notice
• Before use, make sure that the surface of Metering rod and substrate is clean and drying without dust or oil.
• Spreaders need to maintain uniform thrust and stable speed to obtain coatings with consistent Film thickness.
• Wash thoroughly immediately after use to prevent the paint from drying up and clogging the surface Linear dispersion grooves.
• Do not use hard objects to scratch or hit the surface of the rod body, so as not to damage the precision Linear dispersion or hard chrome platings.
• It is recommended to store it in a special bracket or box to avoid collision with Miscellaneous tools.
