Engineering Practice of Chemical Cleaning of Titanium Equipment

There are some difficulties in chemical cleaning of the magnetic oxide scale on titanium equipment.The mixed acid cleaning technology of hydroxyacetic acid and formic acid is used abroad.but due to the expensive price of the hydroxyl acetic acid,it is used less in china.For a titanium equipment for producing salt,a cleaning agent with citric acid as main component was propared and corresponding cleaning method was established.The result of engineering application showed that the cleaning effect was good.
