Overview
RDS 45 #L2000φ 10 wire-wound Applicator rod is a wire-wound Spreader Metering rod produced by RDS Company in the United States. RDS has more than 80 years of experience in R & D and production of coating rods. Its products have become one of the popular film methods due to their simplicity, accuracy, uniformity and economy. The total length of this type of rod body is 2000mm, the effective application width is 1900mm, and it adopts stainless steel 303 mandrel chrome plating process, which is suitable for Spreader needs in a variety of industries.
Features
1. Originating from the American RDS brand, it has more than 80 years of professional production history.
2. Adopting the classic "Mayer" wire winding rod design, the technology is mature and reliable.
3. The wet film thickness is 114.3 μm, which is determined by the diameter of the steel wire of φ 1.14mm.
4. The diameter of the main rod is φ 10mm, the total length is 2000mm, and the effective application width is 1900mm.
5. The mandrel is made of stainless steel 303, and the surface is chrome-plated to enhance durability.
6. Wire winding rod design can be disbonded and re-wound, which helps to save costs and reduce waste.
7. Spreader method is simple and flexible, can quickly change the coating weight and film thickness, suitable for a wide range of substrates.
Principle
The Working Principle of the RDS Wirewound Applicator rod is based on the classic Mayer rod coating method. When the coating flows through the wire tightly wound on the mandrel, the gap (cavity) between the wires determines the wet film thickness of the final Spreader to the substrate. By controlling the pressure of the rod body on the substrate or the tension of the substrate, the Basis Weight Coating can be evenly transferred to the surface of various substrates such as paper and film.
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 RDS Metering rod model (such as wire winding rod, molding rod, etc.).
2. Install the Metering rod correctly on the Spreader equipment and adjust the pressure or substrate tension between the rod body and the support roller.
3. Coating evenly through the surface of the Metering rod, Measurement through the wire gap.
4. The substrate is passed under the Metering rod to complete the Spreader process.
5. Metering rods of different types can be quickly replaced as needed to adjust the Coating thickness.
Notice
* The wire winding rod should be cleaned after use to prevent residual blockage of the coating.
* When operating, choose the appropriate Metering rod type according to the characteristics of Coating viscosity (such as high viscosity Coating can consider notched rod or double wound rod).
When installing, ensure that the rod body is firmly clamped, and the clamping length at both ends meets the equipment requirements.
The chrome-plated surface can extend the life of the rod body, but it is still necessary to avoid scratching with hard objects.
* Wire rewinding rods can be disbonded to save costs, but rewinding needs to ensure accuracy.
For specific application requirements, custom requirements can be submitted to the vendor.
