Corrosion Inhibitor Additives for Water Boilers

Author: Thomas Yoon explains about water boilers in his article...
....scales are very damaging to the boiler because they interfere with the heat transfer and can lead to overheating and eventually, boiler rupture...click here to read the entire article at his blog

By using one of the corrosion inhibitor powders we discussed in our last post, the build up of sediment deposits and damaging corrosion of water boilers is greatly reduced. Most users apply VCI-1 powder to working water boilers at a rate of 0.5 to 1.0 percent of the weight of water in the system. This amounts to 4 up to 8 pounds of powder corrosion inhibitor in 100 gallons of water.

Tarnish Protection Packaging for Silver

Noble metals and non-ferrous metals require a different system or formula to prevent tarnish because of the unique characteristics of these types of metals. Typcially a VCI (vapor corrosion inhibitor packaging) paper or VCI poly packaging is designed to protect a range of metal types. Two broad classifications of types are for FERROUS METALS or for MULTI-Metals. Although Multi-metal VCI packaging products are somewhat effective for corrosion protection of silver, they are ideally suited where a combination of metal types are present. The two types of packaging above do not specifcially target corrosion protection (tarnish prevention) for silver metals.

Anti-tarnish for silver metals is best achieved with a packaging system that is designed specifically for silver and noble metals. This is available in the form of Silver Guard Zipper bags or Silver Saver paper.

Here is a good article posted by krs1 at The Practical Environmentalist about Daubert Rust Remover
I was just doing some research on how to remove rust from home gardening equipment without using caustic chemicals, and found this interesting press release about Evapo-Rust(TM), an environmentally friendly rust removing product that is an alternative to Naval Jelly, the most common way people remove rust from metal tools, car parts, etc. Here's some info from the press release: continue reading rust remover...

VCI Corrosion Inhibitor Powder Additives For Water Systems

When choosing a water additive for corrosion control it is important to know the metals that the water with inhibitor will come into contact. Second is the type of system. Is it open, closed or a recirculating water system such as a cooling system (chiller), heating system, hydro static testing, (pressure test stands), boiler or other type of industrial process water? Is there make-up water coming into the system on a continual or on a batch top up basis? What is the throughput of the system? What is the use of the treated system or finished parts that are being treated for corrosion protection? Is this a lay-up for long term corrosion protection or a short term corrosion control less than 1 year?
