Overview
YONGCHAOMT D10-YC010-L240mm Experimental Spreader Metering rod (bar) adopts precision die cold extrusion processing technology to process concave and convex wavy Linear dispersion on the surface of 304 stainless steel rod body, replacing the traditional winding steel wire coating method. The surface of this product is plated with high hardness hard chromium, which has excellent Abrasion Resistance and service life, and is easy to clean, suitable for laboratory precision Spreader.
Features
1. The use of cold extrusion technology integrated molding, the surface for precision processing of concave-convex wavy Linear dispersion, no traditional winding wire, eliminate the risk of wire loosening or breaking.
2. Linear dispersion on the surface is smooth and smooth, easy to clean thoroughly and easy to maintain.
3. The surface of the rod body is plated with hard chromium coating with hardness up to 1300HV, which significantly improves Abrasion Resistance and prolongs service life.
4. Ultra-thin Film Spreader can be realized to meet the needs of High Accuracy Experiments.
Principle
The Spreader Metering rod is used to Basis Weight Transfer and Spreader Liquid through its surface precision machined concave-convex wavy Linear dispersion. As the rod body rolls on the surface of the substrate, its Linear dispersion groove accommodates and controls the amount of Spreader Liquid, resulting in a uniform, Film thickness accurate wet-film on the substrate. Its design principle is the same as that of the traditional wire-wound drawdown bar, but a more reliable and durable Spreader effect is achieved through the integrally molded Linear dispersion structure.
Applications
Laboratory Precision Spreaders, Coating R & D, Inks Testing, Adhesive Coating, Functional Film Preparative
Steps
1. Ensure that the surface of the Spreader rod and the substrate to be Spreader is clean and drying.
2. Place an appropriate amount of Spreader liquid on the front end of the substrate.
3. Hold both ends of the Metering rod and smoothly contact the groove surface with the liquid and substrate.
4. Pull or push the Metering rod in the direction of the body at uniform speed and pressure to complete the Spreader.
5. After the Spreader is completed, immediately clean the surface of the Metering rod with a suitable solvent and store it properly.
Notice
• Be sure to clean the rod body thoroughly before and after use to prevent the residue from blocking the groove or damaging the surface after drying.
• Please maintain uniform force and speed during operation to ensure the conformity of film Film thickness.
• Avoid hitting the rod body or rubbing against hard objects to prevent damage to the hard chrome platings and precision Linear dispersion structures on the surface.
• Spreader liquid according to the nature of the choice of appropriate cleaning solvent.
Store in a dry, clean environment.
