Overview
The RDS 37 #L1000φ 10 is a wire-wound Applicator rod manufactured by RDS, an American company with over 80 years of history. The product features a classic "Mayer" rod design and is manufactured through a wire-wound process. The Spreader method is simple, accurate, uniform, and cost-effective. It can quickly change the coating weight and is suitable for a wide range of film thicknesses and multiple substrates.
Features
1. Originating from the American RDS brand, with more than 80 years of professional production experience.
2. Adopting the classic Mayer rod design, the technology is mature and reliable.
3. Spreader method is simple, accurate, uniform and cost-effective.
4. Can quickly change the coating weight, apply to a wide range of film thickness, good flexibility.
5. Wire winding rods can be disbonded and rewound, helping to save costs and reduce waste.
6. Provide customized services and can be produced according to specific needs.
Principle
The working principle of the wire-wound Applicator rod is based on the Mayer rod coating method. When the coating flows through the spiral groove formed by the stainless steel wire wound on the mandrel, the excess coating is scraped off, and the amount of coating retained in the groove determines the final wet film thickness applied to the substrate. Accurate and uniform coating thickness control can be achieved by controlling the diameter of the wire (i.e. rod number) and the Spreader operating parameters.
Applications
Coating, window film, adhesive tape, release paper, photovoltaic film, wall covering material, special paper
Standards
The product information does not mention the specific standards it meets.
Steps
Select the appropriate rod number (e.g. 37 #) according to the desired wet film thickness (e.g. 94 μm).
2. Apply the Applicator rod correctly to the Spreader device to ensure that the effective application width (900mm) is aligned with the substrate.
3. Coating is applied so that it flows through the winding area of the Applicator rod.
4. Push or pull the Applicator rod at a steady speed and pressure to scrape off excess Coating and form a uniform wet-film.
5. After the Spreader is completed, clean the Applicator rod in time to prevent the Coating from drying up and blocking the winding gap.
Notice
* Please select the appropriate rod number according to Coating viscosity and required film thickness before use.
* When installing, ensure that the Applicator rod is parallel to the surface of the substrate for uniform coating.
During operation, a steady speed and pressure of the Spreader should be maintained.
After use, it should be thoroughly cleaned immediately, especially the winding gap, to prevent blockage from affecting the next use.
* Use suitable solvents and soft tools when cleaning to avoid damage to the winding or chrome surface.
* Clean and apply anti-rust oil before long-term storage and store in a drying environment.
* Wire winding rod can be disbonded and rewound, but it needs to be operated by professionals to maintain accuracy.
