It has good corrosion resistance and heat resistance, with cheaper cost, and with good surface wetting properties, brittle, fragile is its
biggest drawback. In gas absorption, gas scrubbing liquid extraction process more general use.
It made of a variety of materials available, the main consideration when selecting corrosion problems. Carbon steel low cost, and has a
good surface wetting properties, for non-corrosive or low corrosive Mixtures Preference shall be given; stainless steel corrosion
resistance, in addition to the general ability of Cl-corrosion than common physical system, but its high cost and poor wetting properties of the surface, and in some special occasions (such as low-density spray under vacuum distillation process), need to be treated on its surface, in order to achieve good use of effects; titanium, special alloy steel and other materials made of packing cost is high, generally only in some highly corrosive substance used under the Department. Generally, a metal filler can be made thin-walled structure, its flux, gas resistance, and a high impact resistance in high temperature, high pressure, high impact strength is used, the widest range of
applications.
Materials include polypropylene (PP), polyethylene (PE) and polyvinyl chloride (PVC) and other domestic general use of polypropylene.Plastic fillers better in corrosion resistance, can withstand general inorganic acids, bases and organic solvents. Its tem perature resistance, good long-term 100 掳 C or less. Plastic packing light, cheap, good toughness, impact resistance, non-friable, can be made into thin-walled structures. Its flux, pressure drop, and more for absorption and desorption, extraction, dust and other devices. The disadvantage of plastic fillers poor wetting properties of the surface, but can be an appropriate surface treatment to improve its surface wetting properties.
