Introduction Name:Calcium Chloride Dihydrate CAS No:10043-52-4 Formula:CaCl2 Assay:74%/77% Application Water is a special substance, that is, its density decreases when it freezes. Generally, the density of a substance in solid state is higher than that in liquid state. Therefore, the higher the pressure, the lower the melting point of ice. It is often seen that the snow is easy to melt where the wheels run over. After spraying calcium chloride snow melt agent on the snowy road, it is easier to melt the snow after being rolled by the vehicle. Therefore, spraying calcium chloride snow melt agent is conducive to snow removal. In addition to the need for calcium chloride to dissolve heat, there is another role is to reduce the freezing point of salt water, so it is difficult to form ice after the salt is dissolved in snow water (calcium chloride snowmelt agent dissolved in water or snow, its freezing point is about -20); In addition, after the snowmelt agent is dissolved in water, the concentration of ions in water increases, so that the liquid vapor pressure of water decreases, but the solid vapor pressure of ice remains unchanged. In order to achieve the solid-liquid vapor pressure of ice-water mixture, the ice melts. This principle well explains the fact that calcium chloride salt water is not easy to freeze, and it can deice and melt snow very well.
