Chemical packing is a kind of solid filler, because it is easy to draw materials, easy to manufacture, cheap, so it is widely used.Its function is to provide sufficient contact surface for gas and liquid phases, and to create conditions for enhancing the degree of turbulence so as to facilitate mass transfer.But now chemical packing market mixed, so we choose chemical packing before we need to know our requirements, but also to understand what kind of chemical packing can be used, ruipin packing also for customers do not know the introduction of chemical packing requirements:

The efficiency of packing column is closely related to the chemical packing used. Generally, there are several requirements for chemical packing as follows:

1. Chemical fillers are required to have good corrosion resistance to the processed materials.
2. The chemical packing is larger than the surface, that is, the surface area of the unit volume packing layer is larger.

3 chemical filler itself density (including material and structure) to be small, and by enough mechanical strength.

4. Chemical filler surface wettability is better, and in the structure should be conducive to close contact between the two phases, promote turbulence.
5. Chemical packing void (also known as free volume) to be large, that is, the unit volume of the pore volume of the packing layer to be large.
