Cleaning and Degreasing P2 Fact Sheet

چکیده
Vapor degreasing uses a partially full container of cleaner heated to its boiling point. The parts to be cleaned are suspended in the vapor cloud above the boiling liquid. The vapor condenses on the cooler parts, dissolves the contaminants and flushes the liquid mixture back into the hot liquid. When the cleaning process is complete, the parts are removed from the tank and they quickly dry in the air.

The Avd"* Process: Vapor Degreasing without Chlorinated Solvents
A few years ago, the first semi-aqueous circuit board defluxing composition was developed and introduced by Petroferm. Since that time, several other semiaqueous products have appeared, and semi-aqueous cleaning is now considered one of the leading choices for replacing ozone-depleting CFCs. Now, an advanced vapor degreasing process has been developed which offers the ease of use, fast drying, ...

The use of tetrachloroethylene as a dry cleaning agent, chemical intermediate, and metal degreasing agent has led to its release to the environment. It has also been shown to be produced naturally by several temperate and subtropical marine macroalgae, but the majority of exposure to tetrachloroethylene is still through anthropogenic sources. It is primarily released to the air where it is slow...
