a. Product characteristics:
The packing has advantages such as light, high capacity, low pressure drop, large specific surface area, easy replacement, etc. It is widely used in unit operations like rectification, absorption and extraction. The material's heat resistance reaches 100¡æ for PP and 150¡æ for PVDF. The packing sheet may be perforated with small holes to increase mass transfer efficiency. If the separation requirement is not high, it needs no perforation to increase sheet stiffness.

c. Application fields:
The packing is widely used in absorption and desorption unit operation. It is especially suitable for those processes with high liquid loading and high operation pressure, e.g. hydrochloric acid and sulfuric acid industry, stripping of CO2 and H2S in natural gas, chlorine gas drying, ammonia preparation, purification treatment of waste gases and desorption apparatus.
3¡¢PVC Oblique Corrugation Packing
a. Product characteristics:
PVC oblique corrugation packing produced by our company has features such as high temperature resistance, low resistance, large stiffness and convenient to install. It is a good type of packing for cooling towers.
