Corrosion cleaning agents using

Just as there are strong and weak acids, so too there are strong and weak bases. One very common strong base is caustic soda - sodium hydroxide. This has a powerfully corrosive effect on grease and animal matter, and is often used in cleaning agents for ovens and drains. 

Phosphonates are surface-active chelants and are widely used in industry for scale and corrosion control, and in cleaning agents, dispersants, and other applications. The annual sales of phosphonates in the U S A amount to over two billion dollars per year [8]. Phosphonates inhibit calcium scale formation by interfering with the crystal structure of calcium salts, making the crystals softer so that they are more easily removed by washing - the threshold effect [9]. A key application is controlling scale particularly in hard-to-reach places such as laundry and dishwashing machines. 

Gas propulsion. Here, cleaning agents (which must not be overly corrosive at high temperatures) are propelled through the system by steam. This method is useful for pipelines. 

Review with the owner his operating procedure, include corrosive elements anticipated query him in detail. Determine low and high temperatures anticipated and their duration. Thermal shock is or may be an important factor. Review the type of cleaning to be used, water-hot, cold, steaming. The type of cleaning agents and solutions or solvents can be a factor. 

The obvious method of corrosion control of farm equipment and machinery is to keep it clean and dry after use. Prevention of corrosion under deposits such as mud or waste products prolongs the life of the equipment. Exposure of the equipment to bacteria, fertilizers, cleaning agents, and sanitizing solutions should be minimized. It is also advisable to remove the mud or adhering dirt such as sand particles to decrease wear and possible erosion-corrosion on engines and moving components. 

Surfactants play an important role in the processing of metals. They are used in many treatment steps as emulsifiers, surface-active agents, lubricants, cleaning agents and corrosion inhibitors. 

The cryogenic process uses pelletized carbon dioxide at -73°C as a fluidized abrasive cleaning agent for surface preparation and removal of corrosion and old coatings. Not only does this provide an abrasion mechanism, but certain inorganic salts and organic contaminants can be dissolved with supercritical carbon dioxide. 

Usually corrosion specimens with as-manufactured surfaces are tested without further surface treatment other than cleaning. Corrosion specimens should be cleaned in a cleaner such as 5-10 % aqueous ammonia. An ultrasonic device can be used if available. Because of tightening regulation, organic solvents became undesirable cleaning agents recently. Use... 

Useful life for an aqueous cleaning machine is only 3 to 5 years at best) because of the generally corrosive character of aqueous cleaning agents.
