The stainless steel calendered hole ring packing is a kind of small-particle high-efficient packing, made of metal plate, and the diameter and height of the packing are equal.
Calendered hole ring packing is mainly used in the separation process of laboratory and small batch and high-purity products. Its strength is greater than that of other laboratory fillers.

1. The calendered hole ring material is thin and has a large specific surface area.
2. The air void ratio is large, so the resistance is small.
3. The rolling hole ring mesh is fine and dense, which promotes the surface tension or capillary action. After the filler is soaked, a layer of uniform flow mass transfer film is formed on the surface of the mesh, so the effective utilization rate of the filler surface is high.
Due to the above characteristics, the equal-plate height of the calender hole ring mesh packing is small, its resistance is small, and the solid pressure drop is small. In addition, due to the high surface saturation rate, the liquid holdup per unit volume is large, but due to the small theoretical equal-plate height, this characteristic is very suitable for distillation. Moreover, due to the burr of the calendering ring, the liquid surface is full of unevenness, which is also conducive to the mass transfer process, and the time required to reach the gas-liquid equilibrium is greatly shortened.
