Overview
RDS 19 #L2000φ 10 is a wire-wound Applicator rod produced by RDS Corporation of the United States (founded in 1936), which belongs to the classic "Mayer" rod type. The product uses the wire-wound process to form a precise Measurement gap on the stainless steel mandrel by winding the stainless steel wire to achieve a simple, accurate, uniform and economical film. Its design is suitable for rapid change of coating weight and a wide range of film thickness, with sufficient flexibility, suitable for a wide range of substrates.
Features
1. From the American RDS brand with more than 80 years of experience in R & D and production of coating rods.
2. Using the classic Mayer rod design, the Spreader method is simple, accurate, uniform, and economical.
3. Can quickly change the coating weight, provide a wide range of film thickness selection, suitable for a wide range of substrates.
4. Wire-wound rod design allows for disbonding and re-winding of steel wire, helping to save costs and reduce waste.
5. The mandrel is made of stainless steel 303 and the surface is chrome-plated to enhance durability.
6. Accept customization and provide solutions according to specific needs.
Principle
The working principle of this wire-wound Applicator rod is based on the Mayer rod coating method. As the coating flows through the regular gap formed by the stainless steel wire wound on the mandrel, the excess coating is scraped off by the wire, and the amount of coating retained on the substrate is precisely controlled by the diameter of the wire (i.e. the gap height), resulting in a wet-film of a set thickness. The wet film thickness is mainly determined by the diameter of the selected wire.
Applications
Coating, window film, adhesive tape, release paper, photovoltaic film, wall covering material, special paper
Standards
The data did not mention specific compliance criteria.
Steps
1. According to the required wet film thickness (such as 48.3 μm), select the appropriate wire diameter (such as φ 0.48mm) Metering rod model.
2. Install the Applicator rod correctly in the Spreader equipment to ensure that the effective application width (1900mm) matches the width of the substrate, and the clamping parts (50mm each) at both ends are firmly fixed.
3. Coating evenly flows through the winding area of the Applicator rod.
4. Drive the substrate (such as paper, film) through the bottom of the Applicator rod, the Applicator rod will scrape off the excess Coating, leaving a predetermined thickness of wet-film coating on the substrate.
5. Clean the rod body in time after use to prevent Coating from curing blockage in the steel wire gap.
Notice
• When selecting the model, specify the required wet film thickness to correspond to the correct wire diameter (rod number).
• When installing, ensure that the Applicator rod (total length 2000mm) is placed smoothly, the effective Spreader area (1900mm) is aligned with the substrate, and the clamping parts (50mm each) at both ends are avoided from participating in the Spreader.
• Cleaning and maintenance should be carried out in time after operation to prevent Coating residue from drying up and blocking the winding gap, which will affect the accuracy of the next Spreader.
• The wire winding rod can be disbonded and re-wound with steel wire for repeability, but care should be taken to avoid damage to the rod body.
• For higher viscosity coatings, consider using Miscellaneous models such as notched rods or double-wound rods to reduce clogging.
• This product is a precision Spreader tool and needs to be kept properly to avoid bumping and causing winding deformation or surface damage.
