Clean my hydraulic parts so that could be recycled by filter




Dear sirs
I am making hydraulic parts and searching for a detergent to clean it before assemblying so be recycled and remove any acids and oily surface. Can I use Na2SiO3 (sod)? if yes, please tell me about how to use it?

Hello, Ali. All of the suppliers of metal finishing processes have a wide variety of filterable cleaning solutions pretty much tailored to exact needs depending on production rate, immersion time (or spray time), what other metals may be present besides steel, the nature of the oils and soils, whether electrolytic action or ultrasonic action is available to assist, etc. The Garden State Branch AESF "ELECTROPLATING COURSE MANUAL -- Basic Practical Electroplating" has an outstanding 25-page chapter explaining the various ingredients needed for metal cleaning, but unless you have vast experience in it, buying a packaged cleaner is the only way to go.

A good alkaline cleaner is made up of numerous compounds and can be tailored for specific needs. It is not cost effective to make your own. Talk to any of the major electroplating suppliers about your precise needs. They may want to do a few test parts to sell you an optimum product. They will also tell you how to maintain it for the best solution life and how to test at least 1 of the components.
Have you thought about organic solvents. Commercially Recycled vapor degreaser chemicals work very well as cold solvents.
