Metal degreasing operation using trichloroethylene are categorized in following two categories such as cold degreasing and
vapor degreasing. In cold degreasing trichloroethylene is applied on the metal parts at room temperature, while in
vapor degreasing solvent vapor condensed on the metal parts to be cleaned.
Historically,
vapor degreasing was the default cleaning process for most industries when complex electronic equipment was introduced.
Contract Cleaning: Able provides contract cleaning services on metal parts from
vapor degreasing to complex customer specific cleaning specifications.
* Proposed rule for TCE in
vapor degreasing: December 2016
TCE, which is commonly used in
vapor degreasing of metal parts, can also be found in paint removers/strippers, adhesives and refrigerants.
There are four types of PCB cleaning processes: aqueous (water-based), semiaqueous, emulsion and
vapor degreasing. The main differences between aqueous and semiaqueous cleaning equipment are in the spray bars, cleaning solvents (and subsequent residues), cycle lengths, cleaning solution mixtures, speeds and temperatures.
nPB is used as a
vapor degreasing solvent, a carrier solvent in adhesives and in industrial aerosol products like degreasers.
Looking first at agents then at systems, contributors mostly from chemical and ultrasound companies explore such topics as hydrofluorocarbons,
vapor degreasing with traditional chlorinated solvents, ultrasonic cleaning with two frequencies, from laboratory cleaning to production cleaning, cleaning with micro sandblasters, gas plasma as a dry process for cleaning and surface treatment, and liquid displacement drying techniques.
BACKGROUND: Previous epidemiologic findings suggest an association between exposure to trichloroethylene (TCE), a chlorinated solvent primarily used for
vapor degreasing of metal parts, and non-Hodgkin lymphoma (NHL).
Since its introduction within the United States, 1-BP has been applied as a solvent in many industrial processes, including
vapor degreasing, foam cushion manufacturing, and dry cleaning.
To maintain its diversification, more than 40% of Stabers' business focuses on contract fabrication work involving laser cutting, bending, and welding, as well as
vapor degreasing and powder-coat painting of metal parts and assemblies.
