An ultrasonic degreaser uses energy emitted from a transducer to break up grease and other contaminants on a part.An ultrasonic degreaser is often incorporated into vapor degreasers in industrial degreasing.An ultrasonic degreaser is effective in cleaning parts difficult to degrease using other methods Lucas Moura Brazil Jersey , it is now used widely for certain applications ranging from cleaning a glass lens to degreasing automobile parts. Porous materials such as brass are especially difficult to clean using conventional metal degreasers.Many ultrasonic degreasers are integrated into a solvent cleaning process, components such as filters Lucas Lima Brazil Jersey , rinsers, dryers and other design-specific features are included in the ultrasonic degreaser. Components will vary depending upon the use requirements of the degreaser. Industrial models may be quite large and have multiple chambers while tabletop models for personal use are easily portable.The combination of mechanical cleaning through cavitation and chemical cleaning from the vaporized solvent generally results in a highly satisfactory degreasing.There are two methods that are combined in ultrasonic degreasers: ultrasonic cleaning and vapor degreasing. Ultrasonic degreasers are composed of metal tanks equipped with heating elements in the bottom of the tanks that heat special cleaning solvents to a boil in a closed vessel. As the solvent evaporates it rises to a chamber where the part is placed. Because of the difference in temperature Kaka Brazil Jersey , the solvent condenses onto the part, dissolves the stain and drips off of the part.

Ultrasound may be used alone for parts potentially harmed by immersion in water. The recognition of harmful impact on the environment of solvents classified as ozone depleting solvents (ODS) Jonas Brazil Jersey , industrial degreasing machines have been designed to work with a solvent type that is more environmentally friendly. The ultrasonic degreasers are the last type of solvent degreaser that can be used. This type of unit is similar to the vapor degreasers but it uses ultrasonic waves to clean the parts. The parts that need to be degreased are placed into the tank, and then are sealed off. The ultrasonic components are then turned on for the desired amount of time.Though tightly bonded soils Jemerson Brazil Jersey , greases, and contaminants cannot always be removed with the use of ultrasonic degreasers alone Hulk Brazil Jersey , combining traditional cleaning techniques with ultrasonic cleaning technology has been found to be an effective and environmentally-safe method of cleaning. Ultrasonic degreasers are capable of cleaning individual parts as well as multiple items simultaneously and are used in a variety of commercial and industrial applications in the fabrication, metal processing Giuliano Brazil Jersey , automotive, pharmaceutical Gil Brazil Jersey , electronics and weapons industries.It is ideal for use with traditional solvents like trichloroethylene and methylene chloride, as well as many of the newer solvent. An ultrasonic vapor degreaser has two solvent-filled sumps (the boil sump and the cold sump which is filled with clean Ganso Brazil Jersey , distilled condensate solvent and is often used for rinsing). Near the top of the degreaser is a set of cooling coils that catches the vapor before it escapes from the unit. It cools and condenses it back to its liquid form and flows it back to a clean condensate tank and finally it goes back to the boil sump or the rinse tank.



BEIJING， April 12 (Xinhua) -- A global race is under way to better understand what was behind the outbreak of the Zika virus that began in Brazil last year and has spread to many countries around the world.


U.S. health officials said Monday that the more researchers learn about the Zika virus， the scarier it appears， calling for more funds for mosquito control and for developing vaccines and treatments.


"Most of what we're learning is not reassuring，" said Anne Schuchat， principal deputy director of the U.S. Centers for Disease Control and Prevention. "Everything we look at with this virus seems to be a bit scarier than we initially thought."


Schuchat said that the Zika virus has mainly spread to people primarily through the bite of an infected Aedes species of mosquito and is linked to a broader set of complications in pregnancy， not just microcephaly but also premature birth， eye problems and some other conditions.


Anthony Fauci， director of the U.S. National Institute of Allergy and Infectious Diseases， detailed that Zika may also cause an autoimmune disorder called the Guillain-Barre syndrome， a spinal cord inflammation called acute myelitis， a brain inflammation called Meningoencephalitis， as well as an autoimmune condition called Acute Disseminated Encephalomyelitis， which shares some traits with multiple sclerosis.


"I'm not an alarmist...but the more we learn about the neurological aspects， the more we look around and say this is very serious，" Fauci said.


Both Schuchat and Fauci made the remarks at a White House press briefing， where they were invited to provide an update on this virus and the risk that it poses to the U.S. public.


Schuchat said the Aedes aegypti mosquitoes that spread the virus are present in about 30 U.S. states， instead of 12 states as initially thought.


Meanwhile， the virus is likely to be a problem during much of the pregnancy period， not just the first trimester but potentially throughout the pregnancy， she said.


Health official and experts around the world have reached consensus that the most pressing task now is to advance research and development (R&D) for Zika medical products.


According to the World Health Organization， as of March 2， 67 companies and research institutions were already working on a number of products (31 on diagnostics， 18 on vaccines， 8 on therapeutics， 10 on vector control)， which are at various stages of early development. No vaccine or therapeutic option has yet been tested on humans.
