11.5mm high precision calcined alumina flap disc

  Calcined alumina flap discs are essential tools for grinding, finishing, and blending metal surfaces.

They are made with high-quality calcined alumina abrasive grains that provide exceptional performance

and durability. The flap discs consist of overlapping flaps that are securely bonded to a backing plate,

allowing for smooth and consistent grinding action.

One of the key benefits of calcined alumina flap discs is their ability to maintain a sharp cutting edge and

consistent performance throughout the entire grinding process. This ensures that you can achieve a smooth

and uniform finish on your workpiece with minimal effort.

Additionally, calcined alumina flap discs are designed to be long-lasting and resistant to wear, making them

ideal for heavy-duty applications. They are also suitable for use on a variety of materials, including steel, stainless steel, and other metals.

 

Sealing Function: The ceramic seal disc is designed to create a watertight seal within the faucet assembly, preventing

water from leaking when the faucet is closed or not in use. The precise machining and smooth surface of the ceramic

disc ensure a tight seal to maintain water integrity.

Compression Sealing: When the faucet handle is turned to close the water flow, the ceramic seal disc is pressed against

another surface, such as a metal seat. The pressure applied during closure compresses the ceramic disc against the seat,

creating a secure seal to stop water flow.

Resistance to Wear: Alumina ceramic seal discs are highly wear-resistant, protecting against abrasion and maintaining their

sealing effectiveness over time. This durability ensures long-term performance and minimizes the need for frequent maintenance

or replacement.

Temperature Stability: Alumina ceramic's high-temperature stability allows the seal disc to maintain its properties even when

exposed to hot water in the faucet system. This thermal stability contributes to the reliability of the seal under varying temperature

conditions.

Chemical Resistance: Alumina ceramic discs are resistant to chemicals commonly found in water systems, ensuring that the seal

remains unaffected by water additives or contaminants. This chemical resistance enhances the longevity and effectiveness of the

ceramic seal disc.
