High-pressure Cleaning

picture info	High-pressure Cleaning Pressure washing or power washing is the use of high-pressure water spray to remove loose paint, mold, grime, dust, mud, and dirt from surfaces and objects such as buildings, vehicles and concrete surfaces. The volume of a mechanical pressure washer is expressed in gallons or liters per minute, often designed into the pump and not variable. The pressure, expressed in pounds per square inch, pascals, or bar, is designed into the pump but can be varied by adjusting the unloader valve. Machines that produce pressures from 750 to 30,000 psi (5 to 200 MPa) or more are available. The terms pressure washing and power washing are used interchangeably in many scenarios, and there is some debate as to whether they are actually different processes. A pressure washing surface cleaner is a tool consisting of two to four high-pressure jets on a rotating bar that swivels when water is flowing. This action creates a uniformed cleaning pattern that can clean flat surfaces at a rapid rate. H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Pascal (unit) The pascal (symbol: Pa) is the unit of pressure in the International System of Units (SI), and is also used to quantify internal pressure, stress, Young's modulus, and ultimate tensile strength. The unit, named after Blaise Pascal, is defined as one newton per square metre and is equivalent to 10 barye (Ba) in the CGS system. The unit of measurement called standard atmosphere (atm) is defined as 101,325 Pa. Common multiple units of the pascal are the hectopascal (1 hPa = 100 Pa), which is equal to one millibar, and the kilopascal (1 kPa = 1000 Pa), which is equal to one centibar. Meteorological observations typically report atmospheric pressure in hectopascals per the recommendation of the World Meteorological Organization, thus a standard atmosphere (atm) or typical sea-level air pressure is about 1013 hPa. Reports in the United States typically use inches of mercury or millibars (hectopascals). In Canada these reports are given in kilopascal ...

picture info	Bar (unit) The bar is a metric unit of pressure, but not part of the International System of Units (SI). It is defined as exactly equal to 100,000 Pa (100 kPa), or slightly less than the current average atmospheric pressure on Earth at sea level (approximately 1.013 bar). By the barometric formula, 1 bar is roughly the atmospheric pressure on Earth at an altitude of 111 metres at 15 °C. The bar and the millibar were introduced by the Norwegian meteorologist Vilhelm Bjerknes, who was a founder of the modern practice of weather forecasting. The International System of Units, despite previously mentioning the bar, now omits any mention of it.. The bar has been legally recognised in countries of the European Union since 2004.British Standard BS 350:2004 ''Conversion Factors for Units''. The US National Institute of Standards and Technology (NIST) deprecates its use except for "limited use in meteorology" and lists it as one of several units that "must not be introduced ...

	Pounds Per Square Inch The pound per square inch or, more accurately, pound-force per square inch (symbol: lbf/in2; abbreviation: psi) is a unit of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force of one pound-force applied to an area of one square inch. In SI units, 1 psi is approximately equal to 6895 Pa. Pounds per square inch absolute (psia) is used to make it clear that the pressure is relative to a vacuum rather than the ambient atmospheric pressure. Since atmospheric pressure at sea level is around , this will be added to any pressure reading made in air at sea level. The converse is pounds per square inch gauge (psig), indicating that the pressure is relative to atmospheric pressure. For example, a bicycle tire pumped up to 65 psig in a local atmospheric pressure at sea level (14.7 psi) will have a pressure of 79.7 psia (14.7 psi + 65 psi). When gauge pressure is referenced to something other than ambient atmospheric pressure, then the u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Washdown Washdown (also wash down) is the process of cleaning or washing a surface for appearance, sanitation, or removal of contamination. It may involve pressure washing. Sometimes wash down involves rinsing with fresh water; other times it involves use of detergents and other chemicals. Food processing and packaging machinery Regulations for processing sensitive products such as food and pharmaceuticals require periodic thorough washing and sanitizing. Some equipment can be moved to a central washing facility. Other machinery must be cleaned in place using portable specialized washing equipment. High-pressure cleaning is used with water and cleaning chemicals. A washdown is usually a manual operation and is designed to kill bacteria and other microorganisms. Automatic cleaning of industrial equipment is often carried out by clean-in-place (CIP) and/or steam-in-place (SIP) operations. CIP( CIP) systems often make use of Programmable logic controllers and SCADA software. Decks ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Society For Protective Coatings SSPC: The Society for Protective Coatings (SSPC) is a professional association for the industrial protective and marine coatings industry. It was founded in 1950 as the Steel Structures Painting Council, a non-profit association concerned with the use of coatings to protect steel structures such as bridges, ships, water tanks, and locks and dams. Since the original mission of the organization evolved over the years to include structures built with materials other than steel (concrete, composite materials, etc.), the name was changed in 1997 to SSPC: The Society for Protective Coatings. The organization was originally affiliated with Carnegie Mellon University but is now independent. As of the end of 2019, there are approximately 16,000 members worldwide. There are also approximately 960 corporate members. Industrial painting contractors are a primary beneficiary of SSPC's efforts. Because of significant overlap in mission and services, in April 2020 the membership approved a me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
