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

Wire mesh packing is currently a widely used high-efficiency packing material in various countries around the world. It is a disc-shaped packing composed of several parallel and straight metal corrugated mesh sheets arranged in a row. The corrugation has an inclination angle of 30 degrees or 45 degrees to the axis, and adjacent corrugated sheets have opposite directions. Metal wire mesh corrugated filler has a large specific surface area, high porosity, and light weight; The inclination angle of the gas phase pathway is small, regular, and the pressure decreases; Good radial diffusion, sufficient gas contact, almost no low load limit, and high operational flexibility.   (1) High number of theoretical plates, high flux, and reduced pressure; (2) Good low load performance, the theoretical number of plates increases with the decrease of gas load, and there is almost no low load limit; (3) High operational flexibility; (4) The amplification effect is not easy to understand; (5) Can meet the requirements of precision, large, and high vacuum distillation equipment. The distillation separation of difficult to separate systems, thermosensitive systems, and high-purity products provides favorable conditions. (6) Application of metal wire mesh corrugated packing (7) X-250: Precision distillation with high production intensity and few theoretical plates; (8) X-500: Vacuum distillation with thermal sensitivity and difficult to separate characteristics, especially for vacuum distillation with pressure less than 7KPa. (9) Y-700: Separation of Isotope Mixtures and Isomer Mixtures
