Ultrasonic cleaning machine is mainly divided into solvent-based cleaning machine and water-based cleaning machine two categories. The cleaning agent has the function of decomposition, solubilization, emulsifying, and dispersing in the cleaning process, and then it is cavitated by ultrasonic wave, and the impact will peel off the dirt layer on the surface of the object. The cleaning agent will affect the cleaning effect of the ultrasonic cleaning machine. Therefore, the appropriate cleaning agent should be carefully selected.
The following five elements should be taken into account when selecting:
1. Cleaning effect and efficiency: select effective cleaning solvent through samples and batch experiments.
2, the operation is simple and non-corrosive: the liquid should be harmless, non-corrosive, and easy to operate.
3. Durability and cost: the cost of using cheap cleaning solvents is not necessarily low. When using, we should consider the factors such as high efficiency of solvent cleaning, good durability, how many workpieces can be cleaned by a certain amount of solvent, utilization ratio, etc. The cost of the selected cleaning agent is calculated when the cleaning effect is compatible with the workpiece material.
4, the choice of cleaning agent: try to choose a water-based cleaning agent, because of the ultrasonic machine in the process of heating oscillation, solvent-based cleaning agents than water-based cleaning agent stability, and accident-prone. In addition, the instruction of the ultrasonic cleaning machine will mention that 2/3 of the tank volume should be added to the cleaning fluid, but, some people to save costs, often add a small amount, which may also damage the circuit board and components.
5. Environmental issues: environmental issues can not be ignored. Although Enterprises want to put profit first, with the relevant departments concerned about pollution in all walks of life, not paying attention to environmental protection will inevitably lead to damage to the interests of enterprises. The environment-friendly cleaning agent should have the characteristics of environmental protection and harmlessness. It can degrade the wastewater and make the wastewater discharge reach the legal standard.
