1. Pickling: Soak in 5% nitric acid solution for more than 8 hours at a temperature of 40 degrees Celsius. In ultrasonic cleaning machines. After soaking, rinse inside and outside with filtered deionized water or injection water until neutral, and measure the conductivity. Dry with purified air at a pressure of ≥ 0.4Mpa.


2. Alkali washing: Soak in 3-5% sodium hydroxide analytical pure solution for 30-60 minutes at a temperature of around 40 degrees Celsius. In an ultrasonic cleaning machine, soak and rinse with filtered deionized water or injection water to neutral, measure conductivity, and blow dry with pure air at a pressure of ≥ 0.4Mpa.


Note: Both methods can be used separately or alternatively in combination. If conditions permit, ultrasonic cleaning machines can be combined to achieve the best results.


3. Organic pollution can be combined with surfactant cleaning, while cell debris pollution system combined with enzyme cleaning has a more ideal effect.


4. Titanium rod processing requires frequent online backflushing, which can reduce the number of times the above methods are used for cleaning.
