Overview
The RDS 46 #L2000φ 10 wire-wound Applicator rod is a wire-wound Metering rod that belongs to the classic "Mayer" rod type. It uses a stainless steel 303 mandrel with a chrome-plated surface, a total length of 2000mm, an effective application width of 1900mm, and controls the wet film thickness (about 116.8 μm) by winding a steel wire of a specific diameter (φ 1.17mm). The product originated from the American RDS brand with a history of more than 80 years. With its simplicity, accuracy, uniformity and economy, it has become one of the most popular film methods.
Features
1. Classic Wire Winding Design: Using the original "Mayer" rod process, it has a long history and is widely recognized.
2. Flexible and economical: can disbonding and rewinding steel wire, help to save costs and reduce waste, and no minimum booking and installation costs.
3. Precise specifications: The wire diameter (in mils) directly corresponds to the Coating thickness, providing accurate wet-film control (116.8 μm in this example).
4. Durable material: The mandrel is made of stainless steel 303, and the surface is plated with hard chrome, which significantly prolongs the service life.
5. Customization support: RDS offers a variety of diameters, wire sizes, and bar types (up to 12 feet), which can be customized according to specific application requirements.
Principle
The Working Principle of a Wire-Wrapped Applicator rod is based on the gap formed by the steel wire wound on its surface. When the coating is applied to the substrate and passes through the Metering rod, the grooves between the wires on the rod determine the amount of coating that can pass through, thus precisely controlling the wet film thickness of the coating. The excess coating is scraped off, leaving a uniform, thickness-controlled coating. This method is simple and effective, and the coating weight and film thickness can be quickly adjusted by changing 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. Choose the appropriate wire diameter (rod number) according to the required wet film thickness.
2. Install the Metering rod correctly on the Spreader device.
3. Coating is applied to the substrate surface.
4. Make the substrate with Coating smoothly pass under the Metering rod, and the rod body scrapes off excess Coating to form a uniform coating.
5. Clean the rod body in time after use to prevent Coating from clogging the wire gap.
Notice
• After use, it needs to be cleaned thoroughly in time to prevent the coating from clogging in the steel wire gap.
• During operation, ensure that the rod body is installed smoothly and the contact pressure with the substrate is uniform to obtain the best Spreader effect.
• Although the rewinding rod can be rewound to save costs, the rewinding needs to ensure accuracy to avoid affecting the uniformity of the Spreader.
• For high viscosity coatings, special designs such as notched rods or double-wound rods can be considered to reduce clogging.
• Customized products need to submit detailed requirements through professional tools to obtain accurate quotations.
