What is the structured packing material

The materials of structured fillers mainly include metals, plastics, ceramics and carbon fibers. The specific categories are as follows:

Metal material: such as stainless steel, copper, aluminum, pure titanium, molybdenum five titanium, etc., with large flux, strong impact resistance, high temperature and high pressure resistance, widely used in petrochemical, fragrance rectification and other fields 136.

Plastic material: Mainly polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), light weight, corrosion resistance and low cost, often used in gas purification, water treatment and other scenes 137.

Ceramic material: corrosion resistance, high temperature resistance, but brittle and fragile, mostly used in gas absorption, liquid extraction and other processes 137.

Carbon fiber material: a new type of material, with high strength and lightweight advantages, suitable for special industrial needs 13.

In addition, some structured fillers are also made of special plastic materials such as PTFE (polytetrafluoroethylene) to enhance corrosion resistance and self-lubrication, which is used in chemical industry, environmental protection and other fields. The selection of different materials needs to be comprehensively evaluated according to the specific working conditions (such as temperature, pressure, corrosion) 247.
