Overview
YONGCHAOMT D10-YC030-L240mm Experimental Spreader Metering rod is a professional Spreader tool manufactured by cold extrusion processing technology. It achieves accurate wet-film Spreader by precision machining concave-convex wavy Linear dispersion on the surface of 304 stainless steel rod body, replacing the traditional method of winding steel wire.
Features
1. Using cold extrusion processing technology, the surface of the rod body is an integrally formed concave-convex wavy Linear dispersion, without winding the steel wire, completely eliminating the risk of loosening or breaking the steel wire.
2. Linear dispersion on the surface is smooth and smooth, easy to clean thoroughly and easy to maintain.
3. The surface is plated with a hard chromium layer of high hardness (1300HV), with excellent Abrasion Resistance and long service life.
4. It can achieve the Spreader effect of traditional bar, and is more suitable for ultra-thin film Spreader.
Principle
The Spreader Metering rod Basis Weight transfer coatings by means of a precision machined, height-specific Linear dispersion. As the rod rolls on the surface of the substrate, the raised part scrapes off the excess paint, and the paint retained in the groove is evenly Spreader on the substrate, resulting in a film thickness uniform coating determined by the depth of the groove (here 30 μm wet film thickness).
Applications
Laboratory coating R & D, coating performance testing, inks Spreader, Adhesive Spreader, Precision film prepative
Steps
1. Place an appropriate amount of the paint to be tested on one end of the substrate.
2. Linear dispersion end of the Metering rod is placed behind the paint to ensure that the rod body is in full contact with the surface of the substrate.
3. Pressure evenly by hand and push the Metering rod forward at a constant speed to make the paint evenly scraped.
4. Lift Metering rod to complete Single Spreader.
5. After use, thoroughly clean the surface of the rod body with a suitable solvent, dry it and store it.
Notice
• Before use, make sure that the surface of Metering rod and substrate is clean, drying and dust-free.
• The pressure should be uniform and the speed should be stable during the push process to achieve the best Spreader effect.
• Be sure to clean immediately after use to prevent the paint from drying up in the Linear dispersion groove and affecting the subsequent use accuracy.
• Use a soft cloth or brush when cleaning to avoid scratching with hard objects to avoid damaging hard chrome platings.
• Please store in a drying place to avoid bumping to protect the precision surface.
