Overview
The RDS 13 #L1000φ 10 wire-wound Applicator rod is a wire-wound Spreader Metering rod produced by RDS Corporation of the United States (founded in 1936). The product uses the classic "Mayer rod" design, which forms a measurement gap by wrapping a specific diameter of steel wire on the surface of the stainless steel mandrel. It is used to Spreader a wet-film of a specified thickness on a substrate. Its Spreader method is simple, accurate, uniform and cost-effective, enabling rapid changes in coating weight, and is suitable for a wide range of film thicknesses and a variety of substrates.
Features
1. From a professional coating rod manufacturer with more than 80 years of history.
2. Adopting the classic wire winding (Mayer rod) process, the technology is mature and reliable.
3. Accurate wet film thickness control, Spreader uniformity is good.
4. The mandrel is made of stainless steel 303, with chrome plating on the surface, which has good durability and corrosion resistance.
5. Can be customized according to specific needs, providing flexible solutions.
Principle
The working principle of this wire-wound Applicator rod is based on the pre-metered Spreader technology. As the coating flows through the rod body, a fixed gap (cavity) is formed between the wire wound around the mandrel and the surface of the substrate. The volume of this gap determines the amount of coating transferred to the substrate, thus precisely controlling the thickness of the wet-film. Excess coating is scraped off by the wire, leaving a uniform coating.
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 Spreader process requirements, select the appropriate wire-wound Applicator rod model (such as RDS 13 #).
2. Apply the Applicator rod to the Spreader device or bracket correctly, ensuring that the rod body is parallel to the substrate (or back roller).
3. Adjust the Spreader pressure or substrate tension to achieve the desired Spreader effect.
4. Coating is applied to the pre-rod area.
5. Start the device so that the substrate passes under the Applicator rod at a uniform speed to complete the Spreader process.
6. After the Spreader is completed, clean the rod body in time to prevent the Coating from drying up and blocking the winding gap.
Notice
* Please confirm whether the model of Applicator rod (such as wire diameter, wet film thickness) meets the process requirements before use.
* When installing, ensure that the Applicator rod is firmly installed and parallel to the contact surface of the substrate to ensure the uniformity of the Spreader.
During operation, attention should be paid to controlling the Spreader pressure or substrate tension to avoid damage to the rod or substrate due to excessive pressure.
* Spreader should be thoroughly cleaned immediately after completion to keep the winding gap unobstructed and extend the service life of the rod.
* Please evaluate whether Miscellaneous types of Metering rods such as molded rods, notched rods, or double-wound rods are more suitable for use based on characteristics such as Coating viscosity.
* Wire winding rods can be disbonded and rewound to save costs and reduce waste.
