PVDF Pall Ring Packing

PVDF Pall ring is polyvinylidene fluoride Pall ring filler, the raw material is PVDF polyvinylidene fluoride, the density is 1.77~1.80g/cm3, the melting point is 172°C, the heat distortion temperature is 112~145°C, and the long-term use temperature is -40~ 150°C. PVDF is a high-strength, corrosion-resistant substance. Its applications are mainly concentrated in the three major fields of petrochemical, electrical and electronic and fluorocarbon coatings. Due to its good chemical resistance, processability, fatigue resistance and creep resistance, PVDF is an One of the best materials for equipment packing, pumps, valves, pipes, pipe fittings, storage tanks and heat exchangers for integral or lining of fluid handling systems.

PVDF Pall ring packing is resistant to oxidation, chlor-alkali, Cl2, wet chlorine, H2SO4, sodium hydroxide and other corrosive substances, and can be widely used in place of ceramic, stainless steel and other plastic packing in towers within 167 °C. It will not deformed in boiling water.

PVDF Pall Ring Structural Features and Advantages

PVDF Pall ring structure has the following advantages: There are many windows on the wall of the packing ring, so that the gas and liquid in the packed tower can pass through the windows freely, especially the inner surface of the packing ring is easily wetted by the liquid, so that the inner surface can be Take advantage of. Regardless of the orientation of the Pall ring packed into the tower, the dispersion of the liquid sprayed onto the packing is very high, and the utilization rate of the inner surface of the packing is also high.
