Overview
RDS 12 #L1000φ 10 is a wire-wound Applicator rod (wire winding rod) produced by RDS Company in the United States. It is a classic "Mayer" rod. The product adopts stainless steel mandrel chrome plating process, the wire diameter is 0.3mm (corresponding to 12 #), the total length is 1000mm, and the effective application width is 900mm. RDS has more than 80 years of experience in R & D and production of Spreader Metrod. Its products are widely favored for Spreader's simplicity, accuracy, uniformity and cost-effectiveness. They are suitable for a variety of substrates and a wide range of film thickness requirements.
Features
The brand has a long history: RDS was founded in 1936 and has more than 80 years of professional R & D and production experience.
2. Spreader method is superior: Mayer rod coating method is simple, accurate, uniform and cost-effective, and is one of the popular film methods.
3. Flexible application: can quickly change the coating weight, film thickness range, a wide range of applicable substrates.
4. Proven process: Experience in Coater modification with Metering rods provides solutions for most applications.
5. Customization support: Metering rods in a variety of sizes, materials, and surface finishes are available, up to 12 feet in length, and can be customized.
Principle
The Working Principle of the Wire Wrap Applicator rod is tightly wound on the mandrel based on a predetermined wire diameter (i.e. wire diameter). When the rod body rolls in the Spreader liquid or scrapes across the surface of the substrate, the groove formed between the wound wire and the mandrel determines the wet film thickness transferred to the substrate. The excess coating is scraped off by the wire, resulting in a uniform, thickness-controlled coating.
Applications
Coating, window film, adhesive tape, release paper, photovoltaic film, wall covering material, special paper
Steps
1. Select the appropriate wire winding rod model (such as 12 #) according to the required wet film thickness (such as 30.5μm).
2. Install the Applicator rod correctly on the Spreader device, ensuring it is parallel to the substrate or support roller.
3. Place the material (Coating) to be Spreader in front of the rod body.
4. Move the Applicator rod or substrate at a steady speed to roll the rod over the Spreader area and scrape to form a uniform wet-film.
5. Clean up in time after use to prevent the Coating from drying up and blocking in the gap between the wires.
Notice
• Before use, please confirm whether the Applicator rod model (such as wire diameter and length) meets the Spreader process requirements.
• When operating, ensure that the Applicator rod is firmly installed and the contact pressure with the substrate is uniform to obtain a consistent coating.
• After the Spreader is completed, the rod body should be thoroughly cleaned with a suitable solvent immediately, especially the gap of the wire-wound, to prevent blockage.
• Wire winding rods can be disbonded and re-wound to extend service life and reduce costs, but need to be operated by professionals.
• Avoid bumping or using sharp objects to contact the wrapped wire to prevent damage to the line shape from affecting the Spreader effect.
Store in a drying environment to avoid corrosion.
