Overview
The RDS 8 #L2000φ 10 wire-wound Applicator rod is a wire-wound Metering rod that belongs to the classic "Mayer" rod type. It uses a stainless steel mandrel with a chrome-plated surface, a total length of 2000mm, and an effective application width of 1900mm. It is suitable for Spreader processes in a variety of industries. It has become one of the popular film methods due to its simplicity, accuracy, uniformity and economy.
Features
1. Derived from the American RDS brand with a history of more than 80 years, the process is mature and reliable.
2. Using the classic wire-wound (Mayer rod) design, the Spreader is uniform.
3. The mandrel is made of stainless steel 303 with chrome plating for good durability.
4. Wire winding rods can be disbonded and rewound, helping to save costs and reduce waste.
5. Can be customized according to specific needs, providing flexible solutions.
Principle
The Working Principle of this Wire Wrap Applicator rod is based on the Mayer Rod (Mayer Rod) Spreader method. As the Coating flows through the stainless steel wire tightly wound on the mandrel, the gaps (cavities) between the wires determine the wet film thickness transferred to the substrate. By scraping off excess Coating, a uniform, thickness-controlled coating is left. The wire diameter of this model (0.20mm) is one of the key parameters determining the Coating thickness.
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 Metering rod model (such as the 8 #specification of this product).
2. Install the Metering rod correctly on the Spreader device to ensure stable installation.
3. The coating flows through the surface of the Metering rod, and the Metering rod will scrape off the excess coating to form a wet-film of a predetermined thickness.
4. After completing the Spreader, clean and maintain the Metering rod in time.
Notice
• Although the wire winding rod has a cost advantage, its steel wire gap may be more likely to be blocked than the forming rod, so it needs to be cleaned up.
• After use, it should be cleaned in time to prevent Coating from drying up and blocking the steel wire gap, which will affect the effect of next use.
• Pay attention to protecting the surface of the rod body during operation to avoid bumping and damaging the chrome plating layer or steel wire winding.
• For higher viscosity coatings, consider using models such as notched rods or double-wound rods to reduce clogging.
• The specific selection and operation should be combined with its own process requirements, and customization can be consulted through official channels if necessary.
