Introduction:
Plastic tower packing is made of those heat resistant and chemical
corrosion resistant plastics, including polyethylene (PE),
polypropylene (PP), reinforced polypropylene (RPP), polyvinyl
chloride (PVC), chloridized polyvinyl chloride (CPVC) and
polyvinylidene fluoride (PVDF). It has features such as high void
ratio, low pressure drop, low mass-transfer unit height, high
flooding point, uniform gas-liquid contact, small specific weight,
high mass transfer efficiency and so on, and the application
temperature in media ranges from 60℃to 150℃. For these reasons it
is widely used in the packing towers in petroleum industry,
chemical industry, alkali-Chloride industry, coal gas industry and
environmental protection, etc.
