Overview
YONGCHAOMT D10-YC015-L240mm Experimental Spreader Metering rod is a Spreader tool made with an innovative process. It uses precision die cold extrusion technology to process a specific wavy Linear dispersion on the surface of the steel rod, replacing the bar of traditional wound steel wire, avoiding the problem of loose and broken steel wire, and easy to clean. The rod body is made of 304 stainless steel, and the surface is plated with high hardness hard chrome, which has excellent Abrasion Resistance and long service life.
Features
1. Using cold extrusion technology to process surface wavy Linear dispersion, without winding steel wire, completely eliminate the risk of steel wire loosening or breaking.
2. Linear dispersion is smooth, easy to clean and easy to maintain.
3. The surface is plated with hard chrome platings of high hardness (about 1300HV), with excellent Abrasion Resistance and long service life.
4. The rod body is made of 304 stainless steel, which is sturdy and durable.
5. Accurate wet film thickness (15μm) Spreader can be achieved.
Principle
The Metering rod is used to Basis Weight Transfer and Spreader Liquids through the concave-convex wavy Linear dispersion of its surface precision machining. When the rod body rolls or scrapes on the surface of the substrate, the gap formed by the rod body Linear dispersion carries and controls a specific volume of paint, resulting in a layer of film thickness uniform and accurate wet-film (this model is 15 μm) on the surface of the coated object. Its Working Principle is similar to that of a traditional wound steel bar, but the structure is more reliable.
Applications
Laboratory R & D, Coating performance testing, inks Spreader, Adhesive Spreader, Precision film prepative
Steps
1. Ensure that the surface of Metering rod and substrate to be Spreader is clean and drying.
2. Pour an appropriate amount of the paint to be tested on one end of the substrate.
3. Holding both ends of the Metering rod, scrape or roll the Metering rod from the paint to the other end at a uniform speed and appropriate pressure.
4. After Spreader is completed, clean the surface of Metering rod thoroughly with suitable solvent and store it properly.
Notice
• Be sure to thoroughly clean the rod body before and after use to prevent residual coating curing from affecting the accuracy and damaging the rod body.
• Maintain uniform traverse speed and pressure during operation to ensure consistent film Film thickness.
• Avoid scratching or hitting the surface of the rod body with hard objects to prevent damage to the precision Linear dispersion and hard chrome platings.
• Please select the appropriate cleaning solvent according to the characteristics of the coating.
Store in a drying environment to avoid moisture and rust (although it is made of stainless steel, it is still necessary to pay attention).
