1. Alkali cleaning: Soak the titanium rod in 3-5% sodium hydroxide analytical pure solution for 30-60 minutes at a temperature of about 40 degrees. Good in ultrasonic cleaners. After soaking, rinse with filtered deionized water or water for injection inside and outside until neutral, and measure the conductivity. Blow dry with pure air at a pressure of 20.4Mpa.
2. Pickling: Soak the titanium rod in 5% nitric acid solution for more than 8 hours at a temperature of 40 degrees. Good in ultrasonic cleaners. After soaking, rinse with filtered deionized water or water for injection until neutral and measure the conductivity. Blow dry with pure air at a pressure of 20.4Mpa.
3. The above two methods can be used alone or in conjunction with each other. If possible, it can be combined with an ultrasonic cleaning machine to achieve good results.
4. Organic pollution can be cleaned with surfactants, and debris pollution systems combined with enzymes have good cleaning effects.
