Overview
RDS HJFOSH-V04T1 is a custom wire wound Metering rod (Mayer rod), derived from the American RDS brand with more than 80 years of experience in R & D and production of Spreader rods. The product adopts a formed production process. The mandrel is made of stainless steel 303, the surface is standard chrome plated, the total length is 1500mm, the effective Spreader width is 1200mm, and the design wet film thickness is 9.1 μm. The RDS Metering rod is one of the most popular film methods due to its simplicity, accuracy, uniformity and economy. It is suitable for a variety of substrates and industries.
Features
1. Originating from the American RDS brand, with more than 80 years of professional production experience.
2. Using the classic Mayer rod design, it is a long-standing and popular type of Spreader Metering rod.
3. Supports high customization, allowing for specification selection and quotation according to user-specific needs.
4. The mandrel is made of stainless steel 303, which is sturdy and durable.
5. The surface is treated with standard chrome plating, which helps to extend the service life of the rod.
6. Wire winding rod design allows for disbonding and re-winding, helping to save costs and reduce waste.
7. Spreader method is simple and flexible, can quickly change the coating weight and Film thickness.
Principle
Wire-wound Metering rods (Mayer rods) are based on their precise wire-wound construction. As the paint flows through the stainless steel wire wound on the mandrel, the gaps (cavities) between the wires determine the wet film thickness of the final Spreader on the substrate. By scraping or extrusion, the excess paint is scraped off by the wire, leaving a uniform, film thickness-controlled coating. The wet film thickness is mainly determined by the diameter of the wire used (in mils).
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 application requirements (such as wet film thickness, Spreader width, bar diameter, etc.).
3. Wait for the supplier to quote according to the customized requirements.
4. Confirm indent and arrange production.
5. After receiving the customized Metering rod, install it according to the requirements of the Spreader equipment.
6. Spreader operation, control the coating thickness through Metering rod.
Notice
* Please specify the required wet film thickness, effective Spreader width, total length and other key parameters before customization.
Although the wire winding rod has the advantage of being rewound, care should be taken to avoid damage to the winding structure during operation.
* Select the appropriate type of Metering rod (such as wire winding, molding, notched rod, etc.) to adapt to different viscosity coatings.
After use, it should be cleaned up in time to prevent the paint from drying up and blocking in the steel wire gap.
* Although not explicitly mentioned in the information, Metering rods usually need to be properly installed and fixed according to the requirements of the Spreader equipment.
