According to the different nature of pharmaceutical production requirements solvents and media technology engineering company for titanium filter regeneration procedures are as follows:
1, caustic: 3-5% solution of sodium hydroxide AR soak 30-60 minutes or so a temperature of 40 degrees.titanium alloy sheet Best in ultrasonic cleaning machine. After soaking with deionized water or filtered water for injection and outside the red to neutral, measured conductivity. Dry with clean air ≥0.4Mpa pressure.
2, acid: 5% nitric acid solution soak for 8 hours at a temperature of 40 degrees. Best in ultrasonic cleaning machine. After soaking with deionized water or filtered water for injection and outside the red to neutral, measured conductivity.Medical titanium alloy Dry with clean air ≥0.4Mpa pressure.
3, the above two methods may be used alone may also be used interchangeably with each other. If the conditions can be combined with ultrasonic cleaning machine best.
4, organic pollution can be combined with a surfactant cleaning, cell debris contaminated system conjugating enzyme cleaning effect is more ideal. (Food and drink can be a high concentration of citric acid wash)
Note: grade 3 titanium Always online blowback wash (line cleaning with pure liquid or compressed air or clean water filtration recoil) using the above method can reduce the number of cleaning.
