Cleaning Proteins: pH and Temperature
We run our caustic cleaning at pH 10-10.5. However, the specifications say the nominal pH of a 1% Tergazyme solution is 9.5 Are we compromising cleaning proteins / enzyme performance by using the higher pH and running as part of a caustic cycle? Can we run it at 110F or should we be lower?
Choosing Temperature for Ultrasonic Parts Cleaning
Q. How to determine appropriate temperature to clean parts with ultrasonic cleaner?
A. In general, every 10 deg C you go up in temperature doubles the cleaning speed. The faster you want to clean the hotter you should get.
There is a theoretical optimal ultrasonic cavitation temperature at around 70 deg C depending on the exact concentration of detergent. Even though in theory cavitation…
