Ultrasonic cleaners are highly effective at cleaning dirt and grime, and the types of contaminants cleaned by ultrasonic cleaners vary across different industries. The common types of contaminants in ultrasonic cleaning are as follows:
1.Based on the way scaling occurs in industrial production, the contaminants cleaned by ultrasonic equipment can be classified as scale (such as calcium scale), coal tar, rust, dust, material residues, etc.
2.Based on the hardness of the dirt, ultrasonic cleaning equipment can be divided into hard contaminants and soft contaminants.
3.Based on the density of the dirt, ultrasonic cleaning equipment can be classified into loose dirt and compact dirt.
4.Based on the permeability of the dirt, ultrasonic cleaning equipment can be categorized into permeable dirt and impermeable dirt.
For high-pressure cleaning, operators must fully understand the nature of the contaminants in order to choose the appropriate pressure and suitable high-pressure nozzle for efficient cleaning.
Most of the cleaning agents used in ultrasonic cleaning equipment are liquid detergents, which are composed of surfactants, chelating agents and other additives, as well as organic solvents such as trichloroethylene. Chelating agents and certain metal ions in solution such as Ca2+Mg2+ form stable chelates, thus making the detergent resistant to hard water.
When a substance dissolved in water, even at a small concentration, significantly reduces the surface tension between water and air, or the interfacial tension between water and other substances, the substance is called a surfactant. The molecular structure of a water-soluble surfactant is asymmetric and polar. It adsorbs at the interface between the aqueous solution and other phases, greatly changing the physical properties between the cleaning object, dirt and cleaning medium, especially the interfacial tension at the interface between the phases.
According to the electrical properties of hydrophilic groups when the surfactant is dissolved in water, surfactants can be divided into anionic surfactants, cationic surfactants, neutral surfactants and amphoteric surfactants.
Ultrasonic cleaning machine equipment cleaning requires cleaning agent, divided into liquid detergent and powder detergent. Powdered detergent or cleaning powder is easy to use, easy to load and unload, and easy to store. In the use of the effect, the effect of the two forms of detergent can not be generalised.
