PVDF corrugated packing: a long-term efficiency enhancing tool under strong acid and alkali working conditions

In highly corrosive environments such as concentrated sulfuric acid, hydrofluoric acid, and chlor alkali, the frequent failure of traditional metal/ceramic fillers has become a chronic problem in the industry - equipment downtime, increased maintenance costs, and disrupted production continuity. How to solve this stubborn disease? PVDF corrugated packing is becoming a key solution to replace traditional packing materials in fields such as chemical engineering, environmental protection, and wet metallurgy due to its excellent corrosion resistance.

 ?  Advantages: Maintain near zero corrosion to 98% concentrated sulfuric acid, 40% hydrofluoric acid, concentrated alkali, and organic solvents (measured lifespan>10 years)

 ?  Technical comparison: Corrosion resistant rolled 316L stainless steel, 5 times higher than PP/PE plastic, solves the risk of collapse and fragmentation of the filling layer, and provides dual effect empowerment in structural design

 ? Ripple topology optimization: gas-liquid distribution efficiency increased by 40%, pressure drop reduced by 35% (third-party flow field simulation data)

 ? Lightweight Revolution: With a density of only 1.78g/cm ³, reducing tower load by over 30% and improving seismic and crack resistance performance
