Introduction:
Kynol fiber packing is a specialized type of packing material made from Kynol fibers, which are a type of high-performance novoloid fiber known for their unique properties and wide range of applications. Here is a detailed introduction to Kynol fiber packing:
Composition and Manufacturing:
Material: Kynol fiber packing is made from 100% Kynol fibers, which are impregnated with PTFE (polytetrafluoroethylene) lubricant. This combination enhances the mechanical properties of the packing, providing a balance of softness and strength.
Manufacturing Process: The fibers are processed using a unique PROIM process and then knitted at high speeds to form the packing material. This process ensures the packing has excellent properties such as corrosion resistance, abrasion resistance, and high strength.
Key Features and Benefits:
High Temperature Resistance: Kynol fiber packing does not melt or burn in flames up to 2500°C, making it highly suitable for high-temperature applications. It also exhibits low heat expansion and excellent thermal stability.
Chemical Resistance: The packing is highly resistant to a wide range of chemicals, particularly acids, and is also resistant to organic solvents, oils, and fuels. This makes it ideal for use in chemical plants and other harsh environments.
Dimensional Stability: It maintains high dimensional stability even at elevated temperatures, ensuring consistent performance under varying conditions.
Low Smoke and Toxic Gas Emission: When exposed to flame, Kynol fibers carbonize and emit a small amount of smoke, with minimal toxic gas emission, making them a safer choice for various applications.
Applications:
Industrial Uses: Kynol fiber packing is widely used in industries such as chemical processing, pulp and paper mills, and refineries. It is suitable for use in rotating and reciprocating pumps, washer journals, and liquor pumps.
Abrasive Media Handling: Due to its excellent resistance to abrasion, it is also used in environments where abrasive media are present, and contamination is not permitted.
Technical Specifications:
Temperature Range: The packing can operate effectively in temperatures ranging from -200°C to +260°C in an atmospheric environment.
Pressure Resistance: It can withstand pressures up to 200 bar in static applications, 100 bar in reciprocating applications, and 20 bar in rotating applications.
PH Range: The packing is compatible with a wide pH range of 1 to 13.
In summary, Kynol fiber packing is a versatile and robust material that offers excellent thermal and chemical resistance, making it a preferred choice for demanding industrial applications.
