Overview
The RDS 30 #L2000φ 10 wire-wound Applicator rod is a wire-wound Spreader Metering rod, which belongs to the classic "Mayer" rod type. The product is developed and produced by the American RDS company with a history of more than 80 years. It uses stainless steel 303 mandrel, chrome-plated surface, total length 2000mm, effective application width 1900mm, suitable for Spreader process in various industries.
Features
1. Classic design: Using the popular "Mayer" wire winding rod design since the 1920s.
Specifications are clear: Model 30 #corresponds to a wire diameter of 0.76mm (about 30 mils), which can form a wet film thickness of about 76.2μm.
3. Durable material: The mandrel is made of stainless steel 303, and the surface is plated with hard chrome, which significantly prolongs the service life.
4. Economic and environmental protection: Wire winding rods can be disbonded and rewound, which helps to save costs and reduce waste.
5. Flexible customization: Offers a variety of diameters and wire diameters, up to 12 feet in length, and accepts customization requirements.
Principle
The Working Principle of wire-wound Applicator rod is based on the Mayer Rod (Mayer Rod) Spreader method. A stainless steel wire of a specific diameter is tightly wound around a smooth metal rod core, and the gap between the wires forms a measurement cavity. When an excess of Coating is scraped across the rod body, the steel wire scrapes off the excess Coating, allowing only the Coating of the cavity volume to pass through, thereby forming a wet-coating film of uniform thickness on the substrate and determined by the diameter of the 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, select the appropriate wire diameter (type) Metering rod.
2. Install the Metering rod correctly on the Spreader equipment, ensuring that the rod body is parallel to the substrate or support roller.
3. Coating excess is applied to the substrate in front of the rod body.
4. Make the substrate pass under the Metering rod at a steady speed, and the steel wire on the rod body will scrape off the excess Coating, leaving a uniform wet-film.
5. After the Spreader is completed, clean up the residual Coating on the rod body in time to prevent blockage.
Notice
• Select the appropriate type of Metering rod (e.g. wire wound, molded, notched or double wound) according to the Coating viscosity and desired film thickness.
• After operation, it is necessary to thoroughly clean the rod body in time, especially the wire gap of the wire winding rod, to prevent Coating curing blockage.
• Compared with the forming rod, the wire gap of the wire winding rod is more likely to be blocked, and it needs to be cleaned more carefully.
• Pay attention to avoid bumping when using, protect the wire windings and rod surface platings to maintain Measurement accuracy and life.
• For high viscosity coatings, consider using notched or double-wound rods to reduce clogging and line problems.
