Water-based cleaning is the basic cleaning medium with water, and then add other substances composed of cleaning agents. Such as alkaline cleaning, acid cleaning, surfactant cleaning, saponification cleaning, emulsification cleaning, etc. (for the narrative simplicity, the above cleaning media are “water-based” instead).
A, the basic process
① Basic process 1
The basic process is: [water-based hot dip + ultrasonic 1] → [water-based hot dip + ultrasonic 2] → [hot pure water rinsing ten ultrasonic 3] → [hot pure water rinsing] a → [hot air drying].
②Basic process 2
The basic process two is: [water-based hot spray] → [water-based hot dip wash + ultrasonic 1] → [air knife blowing clean] → [hot pure water spray] → [hot pure water rinse + ultrasonic 2] → [hot pure water spray] → [air knife blowing clean] → [channel hot air drying].
B, the process characteristics
1、Non-combustible and non-explosive, low toxicity, good safety.
2、The composition and concentration of water-based cleaning solution has a variety of options, inorganic pollutants can be easily removed, grease, organic film, water-based lubricating fluid, coolant can also be effectively removed by the chemical process of water, cleaning a wide range.
3、there are multiple cleaning mechanisms, in addition to the role of ultrasonic cavitation, there are dissolution, saponification, displacement, emulsification, suspension and other common action, combined cleaning flexible and effective.
4、low price, wide sources, more economical.
5、its disadvantages are: relatively high surface tension; drying is difficult, energy consumption; there is the problem of sewage treatment; high requirements for cleanliness of the workpiece, surfactants are not easily rinsed clean by water; water-sensitive electronic devices are not suitable for water-based cleaning.
