Overview
YONGCHAOMT D10-YC020-L400mm Experimental Spreader Metering rod is a long bar manufactured by an innovative process. It produces wavy Linear dispersion on the surface of the steel rod by precision die cold extrusion technology, replacing the traditional way of winding steel wire, effectively avoiding the problem of loose steel wire and difficult cleaning, and capable of ultra-thin film Spreader. The rod is 400mm in length, the effective film width is 310mm, and the surface is plated with high hardness hard chrome, which significantly improves Abrasion Resistance and service life.
Features
1. Using cold extrusion processing technology, Linear dispersion is integrally formed on the surface of the steel rod, 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.
3. The surface is plated with hard chrome platings with hardness up to 1300HV, with excellent Abrasion Resistance and long service life.
4. It can realize ultra-thin film Spreader, expanding the application range.
5. Made of 304 stainless steel, the rod body diameter is 10mm, the total length is 400mm, the effective Spreader width is 310mm, and the width of the hand grip part is 45mm + 45mm.
Principle
The Metering rod uses a precision wavy Linear dispersion structure integrally formed on its surface by cold extrusion technology to control the transfer amount of Spreader liquid. When the rod is rolled or scraped on the surface of the substrate, the groove part carries and transfers the Basis Weight coating, resulting in a uniform, Film thickness controllable wet-film on the substrate. Its wet film thickness is determined by the geometry of the surface Linear dispersion, which corresponds to a wet film thickness of 20 μm for this model.
Applications
Laboratory Spreaders, Coatings R & D, inks Testing, Adhesive Spreaders, Functional coatings prepatives
Steps
1. Select the appropriate Metering rod model according to the desired wet film thickness (20μm).
2. Ensure that the surface of Metering rod and substrate to be Spreader is clean and drying.
3. Pour or apply an appropriate amount of paint to the starting end of the substrate.
4. Hold both ends of the Metering rod (hand-held area) and smoothly scrape the rod body across the paint area at constant speed and pressure.
5. After the Spreader is completed, thoroughly clean the surface of the Metering rod with a suitable solvent immediately.
Notice
• Before use, please confirm whether the wet film thickness (20μm) corresponding to the model meets the experimental requirements.
• Maintain uniform speed and stable pressure during operation to ensure uniform film.
• It should be cleaned immediately after use to avoid the paint drying up in the groove of the rod body Linear dispersion, which will affect the accuracy of the next use and damage the platings.
• Use a soft cloth or brush with a suitable solvent when cleaning to avoid scratching the chrome coating on the surface with hard objects.
Store in a drying environment to avoid bumping to protect the surface precision structure.
