Pall ring made of PVDF (polyvinylidene fluoride) is a high-performance plastic filler. Due to its excellent chemical resistance, high purity, low precipitates and other characteristics, it is widely used in petroleum, chemical industry, pharmaceutical and other fields.
The PVDF Pall Ring is a highly porous plastic ring with a unique internal structure. It has 6 side wings, each with many small holes. These small holes allow the fluid to flow smoothly through the packing layer, improving mass transfer. efficiency and uniformity of fluid distribution. In addition, PVDF Pall rings also have good mechanical strength and wear resistance, and can operate stably for a long time under high flow rates and pressures.
Compared with other fillers, PVDF Pall rings have the following advantages:
1. High mass transfer efficiency: The unique internal structure of the PVDF Pall Ring allows the fluid to form a good vortex flow in the packing layer, improving the mass transfer efficiency and uniformity of fluid distribution.
2. High chemical resistance: PVDF material has excellent corrosion resistance and can withstand the erosion of a variety of chemicals, ensuring long-term stable operation of the filler.
3. Low precipitates: PVDF Pall rings are not prone to precipitating harmful substances during operation, ensuring product safety and environmental protection.
4. Good mechanical properties: PVDF Pall rings have high mechanical strength and wear resistance, and can operate stably for a long time under high flow rates and pressures.
5. Easy to clean and regenerate: The surface of PVDF Pall Ring is smooth and not easy to accumulate dirt, making it easy to clean and regenerate.
To sum up, PVDF Pall Ring is an efficient and durable filler with wide application prospects in petroleum, chemical industry, pharmaceutical and other fields.
