Overview
RDS 16 #L1000φ 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 are simple, accurate, uniform and economical, making them one of the most popular film methods. This type of rod body is suitable for rapidly changing coating weight and a wide range of film thickness. It has good flexibility and is suitable for a wide range of substrates.
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 widely used.
3. Customized services can be provided to meet specific application requirements.
4. The mandrel is made of stainless steel 303 and has a chrome-plated surface for good durability.
5. The wet film thickness is accurate, 40.6μm, and the uniformity of Spreader is high.
Principle
The product is a wire-wound Spreader Metering rod. Its Working Principle is to form regular grooves by tightly wrapping a stainless steel wire of a specific diameter (φ 0.41mm) on the surface of the main rod (φ 10mm). As the Coating flows through the rod body, the gap between the wound wires determines the wet film thickness that is ultimately transferred to the substrate. Coating thickness can be precisely controlled by controlling the wire diameter and winding spacing.
Applications
Coating, window film, adhesive tape, release paper, photovoltaic film, wall covering material, special paper
Steps
1. According to the process requirements of Spreader, choose the appropriate Metering rod model (such as RDS 16 #L1000φ 10).
2. Install the Metering rod correctly on the Spreader device to ensure that the two ends are firmly clamped.
3. Adjust the pressure or tension between the Metering rod and the support roller or substrate to control the Coating thickness (for types such as smooth rods).
4. Start the Spreader device so that the Coating flows evenly through the surface of the Metering rod.
5. After the Spreader is completed, clean the Metering rod in time to prevent Coating from clogging the groove.
Notice
* Wire winding rods can be disbonded and rewound to save costs and reduce waste.
* After use, it is necessary to clean the rod body in time, especially the groove of the wire winding rod and the molding rod, to prevent Coating curing blockage.
* For high viscosity coatings, consider using notched rods or double-wound rods to reduce clogging and line problems.
* Pay attention to the protection of the rod body during operation to avoid bumping and damaging the surface platings or wire-wound structures.
* Customized Metering rods need to submit specific requirements through professional tools, and the manufacturer will quote and produce them.
