Rinse Tank Water PH

What effect, if any, will raising the temperature of RO water in a post-anodize, post-chromate rinse tank from ambient to 130°F have on the water’s pH value? Is there a way to rinse in hot RO water, max 130°F, and still be able to maintain a pH level on the part between 5.5 and 8.0 or the water in the rinse tank?

“Fuzzy” Parts

We are noticing that some of the parts form a “fuzz” where they are machined. This area is white powder and when removed leaves a black spot on the surface of the tube that will not chromate.

Hazey Parts

The cleaner we used for four years worked great until recently. After the initial few days of the new bath, the parts start to develop a haze when cleaned. Is this a water issue? Should I put a water softener on the water supply? Is it some kind of build up inside the washer? Should I descale? Any Ideas?

FRP Parts Washer

I am considering the use of a 5 stage part washer constructed from FRP (Fiber Reinforced Plastic). Do you or know anyone who has any experience with a washer constructed from this material? It is intended to wash mild steel sheet metal parts.

Replaced Liner Just Isn't The Same As The Old

The liner on our Osrotron 10-cu-ft bowl wore out and we decided to reline rather than purchase a new machine. When we got the bowl back with the new liner, we could not adjust the machine to the same good action we had before. Our supply vendor is not qualified to help with this. We don’t know where to turn for assistance since Osro is out of business.

Pretreatment

I am setting up a new Batch operation and wanted to know which pretreatment to go with. A 3 stage dipping system, or is a 3 stage hot pressure cleaning solution wash, Clear Rinse and sealant? Will the Iron railings benefit from a 3 minute dipping more than a power wash manually?

Passivating Brass Shell Cases after Pickling/Polishing

Question: I am running a mass finishing process that requires an aqueous passivation of the brass as a final process to help prevent corrosion.
