Overview
YONGCHAOMT D10-YC030-L400mm Experimental Spreader Metering rod is a Spreader tool made with an innovative process. It uses cold extrusion technology to process precision wavy Linear dispersion on the surface of the steel rod, replacing the traditional way of winding the steel wire, effectively solving the problem that the steel wire is easy to loose and difficult to clean, and can achieve a more uniform Spreader effect. The rod length is 400mm, the effective film width is 310mm, and the surface is plated with high hardness hard chrome, which has excellent Abrasion Resistance.
Features
1. Linear dispersion is integrally formed on the surface of the steel rod by cold extrusion process, without winding the steel wire, which eliminates 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 hard chromium with hardness up to 1300HV, which significantly improves Abrasion Resistance and service life.
4. It can achieve a more uniform and stable Spreader, especially conducive to the application of ultra-thin film Spreaders.
5. The main body is made of 304 stainless steel, which is sturdy and durable.
Principle
Measurement and control of the film thickness of the Spreader liquid is achieved by the Metering rod through the precision-machined concave-convex wavy Linear dispersion on its surface. When the rod rolls or scrapes on the surface of the substrate, the excess liquid is scraped off by the raised part of the wavy Linear dispersion, and the groove part leaves a wet-film of predetermined film thickness, thus achieving accurate wet-film Spreader. Its wire-free integrated design ensures the stability and conformity of the Spreader process.
Applications
Laboratory research and development, coating performance testing, inks Spreader, Adhesive Spreader, functional coating prepative, paper surface preparation, film material coating
Steps
1. According to the required wet film thickness, refer to the model selection table to select the appropriate Metering rod model.
2. Ensure that the surface of Metering rod and substrate to be Spreader is clean and drying.
3. Pour or drop an appropriate amount of Spreader liquid onto one end of the substrate.
4. Hold both ends of the Metering rod and scrape the rod smoothly across the liquid area at constant speed and pressure.
5. After the Spreader is completed, immediately clean the surface of the Metering rod with a suitable solvent and store it properly.
Notice
• Before use, please confirm whether the wet film thickness corresponding to the model meets the experimental requirements.
• Maintain uniform speed and stable pressure during operation to ensure uniform film Film thickness.
• Spreader should be thoroughly cleaned immediately after completion to avoid residue drying up and clogging the groove.
• When cleaning, it is recommended to use a soft cloth or a soft brush to avoid scratching the surface platings with hard objects.
• When storing, avoid bumping, keep drying, and prevent rust (although the main body is stainless steel and chrome-plated).
• This product is a precision tool, please do not use it for non-Spreader purposes or withstand improper external force.
