Anhydrous calcium chloride CAS No.: 10043-52-4
Formula: Cacl2
EINECS: 233-140-8
HS CODE:2827 200000
Anhydrous calcium chloride refers to calcium chloride without crystalline water. Typically, calcium chloride can exist in hydrated or anhydrous forms. The chemical formula for anhydrous calcium chloride is CaCl₂. At room temperature, it is a white solid with hygroscopic properties, rapidly absorbing moisture from the air to form hydrates.
Anhydrous calcium chloride is widely used in various fields, such as:
- Desiccant: Due to its hygroscopic nature, anhydrous calcium chloride is commonly used as a desiccant to absorb moisture from the surrounding environment. It is utilized in many industrial processes for dehumidification and drying.
- De-icing Agent: Anhydrous calcium chloride is also used as a de-icing agent for roads. It can absorb surrounding moisture and release heat, aiding in the melting of ice and snow.Calcium chloride has long been proven as a professional grade snow and ice melter. It consistently delivers safe surfaces for commercial and residential building owners and facilities managers without damaging granite steps, tile entrance ways, or sensitive environmentally friendly landscape features and surrounding vegetation.
- Phase Change Materials: Because of its hygroscopic and heat-releasing properties, anhydrous calcium chloride can serve as a material in some phase change systems, used for storing and releasing thermal energy.
- Calcium Chloride for Dust Control:Use our dry calcium chloride for dust control and fugitive dust suppression.Advantages of Using Calcium Chloride Flakes and Pellets for Dust Suppression Calcium chloride is the first choice for road dust control products. Why? The reasons are many:
Calcium chloride is hygroscopic, meaning it attracts moisture from the air and its surroundings. This keeps unpaved surfaces damp and the dust down.
Cal chloride also resists evaporation, so a single application provides ongoing benefit.
Calcium chloride’s thirst for moisture helps bind aggregate particles together. Unpaved surfaces become and remain compacted and over time, the chemical penetrates the surface adding a stabilizing effect to reduce frost damage and overall wear.
Maintenance costs for a calcium chloride-treated road are much less than untreated roads.
Dry CaCl2 in flake and pellet form will work well in most existing equipment that is set up to spread sand and salt products in the winter. New England Townships have used calcium chloride to manage unpaved surfaces, including dirt roads and parking areas, for years. This cost effective process reduces the amount of labor required to maintain unpaved surfaces that typically require grading and rolling several times of year when calcium is not applied. Our most popular calcium chloride dry products for dust management are our calcium chloride flakes in super sacks and 25kg bags, and our calcium chloride pellets.
Whether building new roads or rehabilitating existing roads, simply spreading calcium chloride on the surface, or using it in full-depth reclamation technique, calcium chloride is the dust control material of choice.
