Calcium Chloride

FOTO-32

Calcium Chloride aqueous solution is produced from controlled and extremely pure raw materials with the following chemical reaction, which does not create any adverse by-products:

cloruro-di-calcio-formula

In addition to the high content in CaCl2, one of its main properties is the low concentration of sulphate and heavy metals (ppm). Calcium chloride is produced in concentrations of 34-36%  and is also available diluted at 25-27%.

Calcium Chloride Properties

The main characteristic of calcium Chloride is the electrolytic one which is able to low the freezing point of the aqueous solutions that contain it. The lowest temperatures reachable by these solutions are shown in the chart below, while a different product also used as antifreeze agent cannot reach temperatures under -21°C.

It is also important calcium chloride’s rheological behavior, below the values of viscosity in function to temperatures (from -20°C to + 100°C) related to the concentration of salt in the solution.

The properties described make Calcium Chloride an useful and easy product for removing ice on surfacing in winter treatments (de-icing). Its fluidity even at temperatures below 0°C allows to apply it with vehicles that disperse it on surfacing in liquid form, moreover it is able to persist for a long time after its application as antifreeze (anti-icing). Calcium chloride is an effective deicer, working at temperatures below most competing products, and is significantly more effective than sodium chloride because of its ability to extract moisture from its surroundings and to cause exothermic or heat generating reactions. Also, its effect on vegetation, corrosive characteristics, and concrete performance compares favorably to competing ice-melt materials.
