What material is used for filtering corrosive liquids

September 13,2023

When dealing with corrosive liquids, it is necessary to use filter bag materials with corrosive resistance to ensure filtration efficiency and durability of the filter bag.

The following are commonly used filter bag materials for filtering corrosive liquids:

Polypropylene (PP) filter bag:Polypropylene material has excellent corrosion resistance, exhibiting excellent corrosion resistance under low to acidic and alkaline conditions. Polypropylene filter bags have a long service life and can be reused.

Polyester (PE) filter bag:Polyester material has good corrosion resistance and high temperature resistance, and can be used within a certain temperature range, usually reaching over 100 ℃. Polyester filter bags have high filtration efficiency and can filter out small particles and sediment.

PTFE filter bag:PTFE material has excellent corrosion resistance, high temperature resistance, and corrosion resistance, and can be used in extreme acidic and alkaline conditions. The filtration accuracy of polytetrafluoroethylene filter bags is high, which can filter out small particles and precipitates.

It should be noted that when selecting filter bag materials, the selection should be based on the specific characteristics of corrosive liquids and filtration requirements. In addition, when using corrosive liquid filter bags, attention should be paid to protecting the safety of operators and the environment to prevent the harm caused by the corrosion of filter bag materials. At the same time, it is necessary to comply with relevant safety operating procedures when using filter bags to ensure their normal use and replacement.
