Overview
RDS custom bar (model: 6 #L500φ 9.5) is a Spreader Measurement tool based on the classic Mayer rod coating principle. As an American professional manufacturer with more than 80 years of history, RDS products are widely used in various industries such as coatings, window films, tapes, release papers, photovoltaic films, wall covering materials and specialty papers with the characteristics of simplicity, accuracy, uniformity and economy. This model is Wire-wound metering rods, which can be customized according to specific needs.
Features
1. Originating from the American RDS brand, it has more than 80 years of professional R & D and production history, with reliable quality.
2. Adopting the classic wirewound rod ("Mayer" rod) design, the technology is mature and widely used.
3. Spreader method is simple, accurate, uniform and cost-effective, can quickly adjust the coating weight and film thickness.
4. Good flexibility, wide range of applicable substrates, can provide a simple solution for Coater transformation.
5. Customization is supported, and specifications can be selected and quoted according to the specific needs of users.
Principle
Wire-wound Metering rod's Working Principle is based on the Mayer rod coating method. A uniform cavity is created between the wires by wrapping a wire of a specific diameter on a precision stainless steel rod. These cavities determine the wet Coating thickness retained on the substrate as the rod rolls or scrapes over the Spreader substrate. Excess paint is scraped off, resulting in a uniform, controlled coating.
Applications
Paint, window film, tape, release paper, photovoltaic film, wall covering material, special paper
Standards
The data did not mention specific compliance criteria.
Steps
1. Submit customization requirements through the NBchao Metering rod customization tool.
2. Specification selection according to specific needs (such as production process, wet film thickness, size, etc.).
3. Wait for the manufacturer to quote according to the customized requirements.
4. Confirm indent and arrange production.
Notice
* This product is a customized model, and the specific specifications (such as production process: wire-wound, wet film thickness: 13.7μm, diameter: 9.5mm, total length: 500mm, effective application width: 400mm, clamping length at both ends: 50mm) need to be clear when placing an order.
* Wire winding rods can be disbonded and rewound to save costs and reduce waste.
* For coatings of different viscosity, Miscellaneous types of Metering rods such as molding rods, notched rods, or double-wound rods can be considered to achieve better Spreader effect.
* Spreader pressure or tension should be adjusted according to the coating characteristics and process requirements to control the coating thickness.
