A flux designed for Pb-free processing can volatilize
until 217[degrees]C when used with SAC alloy solders, but its outgassing paths will be closed at 183[degrees]C if used with SnPb solders.
The chemicals volatilize
on warm days, then enter the water system when blown over the lakes or the rivers and streams that feed them.
Since many dish detergents contain chlorine, Corsi suspects that as they react with food scraps, they "will form some pretty nasty chlorinated organics in the dishwasher, and they will volatilize
." This will add to whatever chemicals had been in the water, he says.
In conjunction with Se uptake, cultivars are evaluated for ability to volatilize
Se as a gaseous compound (18).
Today we rely on organic acids and materials that volatilize
at soldering temperatures to reduce solids content.
While they work well in blown films processed at 400 F, they tend to volatilize
at higher temperatures.
If ample time is not permitted for flux to volatilize
, harmful (conductive and moisture-absorbing) residues inherent in flux chemistries will remain and create potential for electrochemical failures.
Studies from the late 1980s suggested that plants volatilize
about 30 percent of the selenium entering a wetland.
The lid quickly creates a reducing atmosphere in the crucible, in which only live carbons and additives that can volatilize
gases will be detected.
Hydrazine's issues are pretty well documented, so we went up to the next larger molecule, which was ethylene diamine." She says one advantage to ethylene diamine is that it remains a liquid at room temperature, unlike ammonia-based solvents, which volatilize
at or near room temperature.
Because many toxic chemicals can volatilize
out of water, Bhattacharya's group decided to look at postural sway in 28 apparently healthy wastewater-treatment workers.
