Overview
RDS 9 #L1000φ 10 wire-wound Applicator rod is a wire-wound Metering rod produced by RDS in the United States. RDS has more than 80 years of experience in R & D and production of Spreader Metering rod. Its products are based on the classic Mayer rod coating method. It is known for its simple operation, accurate and uniform Spreader, and cost-effective. It can quickly change the coating weight and achieve a wide range of film thicknesses. It is suitable for a wide range of substrates. This model is a wire-wound coating rod with a wet film thickness of 22.9μm.
Features
1. Derived from the American RDS brand with a history of more than 80 years, the technology is mature and reliable.
2. Adopt the classic "Mayer" wire winding rod design, which is widely used.
3. Spreader method is simple, accurate, uniform and economical.
4. Can quickly change the coating weight, to achieve a wide range of film thickness, high flexibility.
5. Suitable for a wide range of substrates, providing solutions for most applications.
6. Wire winding rods can be disbonded and rewound, helping to save costs and reduce waste.
7. Accept customization and can be produced according to specific needs.
Principle
The RDS wire-wound Applicator rod works based on the Mayer rod coating principle. When the Spreader liquid flows over the surface of the Metering rod, the regular grooves (cavities) formed between the precision wire wound on the mandrel and the mandrel determine the final thickness of the coating. The excess Coating is scraped off by the wire, leaving only the Coating in the grooves, resulting in a uniform, controllable wet-film on the substrate.
Applications
Coating, window film, adhesive tape, release paper, photovoltaic film, wall covering material, special paper
Steps
1. According to the Spreader process requirements, select the appropriate RDS Metering rod model (such as wire winding rod, molding rod, etc.).
2. Install the Metering rod correctly on the Spreader device.
3. Spreader liquid flows through the surface of the Metering rod.
4. The groove formed by the steel wire on the Metering rod precisely controls and scrapes off the excess Coating to form a wet-film of a predetermined thickness on the substrate.
5. After completing the Spreader, clean and maintain the Metering rod.
Notice
* Wire winding rods can be disbonded and rewound to save costs and reduce waste.
The grooves of the molding rod (Slotting rod) are less likely to clog and easier to clean than those of the winding rod.
* For high viscosity coatings, consider using notched rods or double-wound rods to reduce clogging and eliminate lines.
Double-wound rods are more durable than notched rods, but they are also more expensive.
* Smooth rods are commonly used to smooth a Measured Coating whose Coating thickness is controlled by pressure or tension.
Users can submit specific requirements for product customization through customization tools.
