Water-soluble cleaning metal parts

Water-soluble cleaning metal parts
In the metal processing industry is the need to ultrasonic cleaning, and use it to remove oil, oily grease, metalworking fluids, abrasive polishing agents and metal fine and workshops specific contaminants like dust, 1.1.1 trichloroethane and the like cleaning agent mainly by CFC-113 azeotropes composed of carbon and chlorine, has been widely used to remove these impurities, but these solvents associated with the impact of the ozone layer, so the phase out production and use of Chiang Kai-shek.

The use of aqueous solutions and the newly developed semi-aqueous chemical solution is environmental protection departments authorized replacement product above combination of ultrasonic processing to achieve the same situation with the past with the cleanliness of the solvent, for those with blind holes, grooves or complex geometry of the metal parts, the ultrasound has outstanding advantages.

Newly developed semi-aqueous chemical solution has a remarkable feature is that they are very specific applications. Will be able to write these letters have a new chemical solution used successfully to clean metal parts of the detailed report.

Ai V also designed special for the semi-aqueous cleaning fluid equipment, rinse with special consideration of its arrangement.

Semi-aqueous chemical solution is used to balance the quality of dissolved organic and inorganic components of the hydrocarbon solvent in the cleaning liquid is broken down in the dirt and rinse water was continuously washed out in the rinse water at the organic dirt and hydrocarbon components from the effluent limitation separated, but because of their chemical properties for the sake of complete removal of the solution, at least the need for two separate rinse thoroughly when any process contains water, must be included in the final processing stage drying.

Inorganic water-based cleaning fluid is a chemical solution, which emulsified, dispersed or dissolved in the liquid dirt. By means of ultrasound, they are to remove dirt and organic matter can be quite a performance.

In this essay, explain and evaluate these two kinds of replacement solvent ultrasonic cleaning technology.

Cleaning valve requirements:
Light oil from the valve clearance and cutting oil.

Before cleaning method:
With FC-113 for alcohol azeotrope solvent or vapor cleaning.

Recommended approach:
l the valve immersed in the heating 40KHZ ultrasonic cleaning tank 3 minutes, the tank is stored in the temperature of 1400F oil emulsion in alkaline solution. the use of the volume concentration of 5%.
l of hot water with the 1500F spray 45 seconds.
l use of ultrasound in 1500F of hot water rinse tank by three cascade 3 minutes at a flow rate 1GPM.
l using air knife hair, then use the evaporation of high purity 2800F hot air dryer drying.

Equipment: a dryer Branson ultrasonic cleaning system containing aqueous solution, and the combination of a TDR-50 type automatic transmission.

Advantages:
l avoid the use of CFC-based (CFC) solvents.
l do not need to look for those who can prove effective cleaning oil replacement.
l the use of pumps and filtration equipment ultrasonic cleaning solution can be removed from the emulsified oil. to extend the use of clean solution time.
l make the product more light more attractive.

Clean bearing requirements:
Without the use of CFCs in the case, remove grease from stainless steel bearings and oil, to achieve the last commonly used cleaning solution has the same cleanliness.

Before cleaning method:
Conducted with 1.1.1 trichloroethane solvent or steam cleaning.

Recommended approach:
l to the level of immersion bearing heating at 40KHZ ultrasonic cleaning tank 5 minutes, the tank is the temperature of 1250C semi-aqueous solutions. the use of high concentration solution.
l of hot water at 1500F, the use of ultrasonic overflow rinse for 90 seconds at a flow rate 0.3GPM. sewage into the dirt or make the separation of hydrocarbon material and water separation tank.
l of hot water at 1600F, the three cascade rinse tank 3 minutes at a flow rate 1.5GPM.
l using air knife hair, then blow hot air dryer with a drying, drying temperature of 2400F.

Equipment:
Branson ingredients or semi-aqueous continuous treatment with dryer washing machine.

Advantages:
l enhance the cleaning ability of ions and organic dirt
l do not need to change the current process used in the manufacture of oil or lubricant.
l better process control ---- simple processing techniques. does not require complex monitoring.
l ---- to help protect the environment and hydrocarbon organic matter dirt separated from the water, thus reducing the load handling equipment cleaning.
