However, such cleaning agents contain ozone layer-damaging substances, and improper use of halogens and compounds thereof can bring harm to the body and environment of workers in the production process, and ODS is gradually forbidden along with the improvement of safety and environmental awareness.
The halogen-free cleaning agent adopted at present mainly comprises low-flash and low-boiling-point solvents such as alcohols, ketones, alkanes and lipids, the cleaning agent has less residues after cleaning but has higher cost, toxicity, flammability and explosiveness and high volatility, and in addition, the low-carbon alcohols can cause the whitening phenomenon on the cleaned surface because of strong water absorption.

Although the cleaning requirements can be basically met, on one hand, most cleaning agents have strong dependence on the types of brazing filler metal and soldering flux, limited cleaning range and poor stability, are volatile and are harmful to human health. On the other hand, most of cleaning agents are complex in preparation method, other auxiliary equipment needs to be introduced, the cleaning agents are complex in components, corrosion can be caused to welding points, a large amount of bubbles can be generated in the cleaning process, and the cleaning agents cannot be used for full-automatic cleaning and ultrasonic cleaning.
