pH level of Aluminium Bright Dip
2005
Dear Sir/ Madam;
I found your article on the web and would like to enquire more information.
I am experimenting the Aluminium Bright finishing on sandblasted surface (grade of sand is fine).I have a drum of 25 liters of this chemical and my component (workpiece) is 60 diameter and 75 mm long.
Question is how many of this size of the workpiece that I continue using this chemical before I need to "top up" or replenished.
Is there a guideline that I can worked on?
I understand that normally the chemical concentration is measured by Ph level. In this case, what Ph level is deemed not effective to be used.
I appreciate your reply in advance.
Regards
