1. Corrosion resistance:

 Titanium is an inert metal with excellent corrosion resistance. The titanium rod filter element made of titanium metal can be filtered in a medium with strong alkali and acid. Can be widely used in the chemical industry, in the pharmaceutical industry organic lysoin production process filtration, due to the application of organic solvents, if the use of polymer filter elements such as: PE, PP filter elements to filter, easy to be dissolved by these organic solvents, and titanium rod in the organic solvent medium is quite stable, widely used.

Corrosion resistance of titanium filter media:

A: Corrosion resistance, corrosion rate below 0.127mm/year.

B: Compared with corrosion resistance, the corrosion rate is below 0.127mm-1.27mm/year, which can be used.

C: For corrosion resistance, the corrosion rate is more than 1.27mm/year, which is not recommended.
