Description of the technical principle

1) It lowers the freezing temperature by the third-party chloride injection. However, when the chloride is lost by the vehicle wheels or the salt dissolved by melting snow and ice is discharged into the sewer.

2) To solve the above problems, insoluble sulfide PCM and paraffin PCM are mixed to maintain anti-freezing for a long time.

3) Since insoluble PCM does not dissolve in water, it can maintain phase change performance for a long time. Therefore, chloride PCM is dissolved and fine particle pores are generated, and in the fine particle pores generated, sulfide PCM and paraffin PCM that are not dissolved in water change from solid to liquid and settle in the fine particle pores.

4) By adjusting the phase change temperature of sulfide PCM and paraffin PCM to be lower than that of chloride PCM, the liquid can be re-settled in the fine particle pores created by the dissolution of chloride PCM.

5) Even if chloride PCM is continuously dissolved and lost, sulfide PCM and paraffin PCM can fill its place, thereby maintaining anti-freeze.

6) Anti-freeze temperature can be achieved at a minimum of -16 degrees, but the anti-freeze temperature decreases over time as the dissolved chloride PCM disappears.

7) Compared to other companies' products, the black ice phenomenon can be minimized at -5 degrees or higher, and traffic accidents can be reduced with sufficient anti-freeze in shaded areas and mountainous regions.
