Overview
RDS 7 #L1000φ 10 is a wire-wound Applicator rod produced by RDS Company in the United States. RDS company has more than 80 years of experience in R & D and production of Spreader Metering rod, and its products are widely popular in the Chinese market. This model adopts wire-wound process, the mandrel is made of stainless steel 303, the surface is chrome plated, the total length is 1000mm, and the effective application width is 900mm. It is suitable for Spreader applications in various industries.
Features
1. Derived from the American RDS brand with a history of more than 80 years, with reliable quality.
2. Adopt the classic "Mayer" wire winding rod design, which is widely used and popular.
3. Wire winding rod structure can be disbonded and re-wound, which helps to save costs and reduce waste.
4. More than 70 wire sizes and 15 bar diameters are available to meet different Spreader thickness requirements.
5. Accept customized services and can produce according to specific needs.
Principle
The Working Principle of the wire-wound Applicator rod is based on the Mayer rod coating method. As the coating flows through the precision wire wound on the mandrel, the gap between the wires determines the thickness of the wet coating. Through the scraping action, the excess coating is scraped off by the wire, leaving a uniform, thickness-controlled coating. This method is simple, accurate and cost-effective.
Applications
Coating, window film, adhesive tape, release paper, photovoltaic film, wall covering material, special paper
Steps
1. Select the appropriate Metering rod model (e.g. 7 #) according to the desired wet film thickness (e.g. 17.8 μm).
2. Install the Metering rod correctly on the Spreader device to ensure that the two ends are firmly clamped.
3. Place the substrate to be Spreader flat.
4. Coating is applied to the substrate in front of the Metering rod.
5. Push or pull the Metering rod at uniform speed and pressure for scraping.
6. After the Spreader is completed, clean the Metering rod in time.
Notice
* Before use, please confirm whether the Metering rod model (such as steel wire diameter φ 0.18mm, main rod diameter φ 10mm) meets the process requirements.
* Maintain uniform scraping speed and pressure during operation to ensure consistent Coating thickness.
* After the Spreader is completed, the rod body should be thoroughly cleaned with a suitable solvent immediately to prevent the Coating residue from clogging the wire gap.
* Wire winding rod can be disbonded and re-wound, but professional operation is required to maintain accuracy.
* Avoid bumping when storing to prevent wire deformation from affecting the Spreader effect.
* For high viscosity coatings, consider using notched rods or double-wound rods to reduce clogging.
Customized products require specific requirements to be submitted through official channels.
