Calcium Chloride Applications

1. Snow and Ice Melting (Main Application)

It is used for de-icing and snowmelting on roads, airports, and highways. It melts ice quickly and effectively at low temperatures, making it a common chemical for preventing slippery roads in winter.

2. Construction and Concrete Engineering

It is used as a concrete accelerator and antifreeze, improving concrete strength and accelerating hardening, making it suitable for construction in cold regions.

3. Desiccant (Desiccant)

Anhydrous calcium chloride is used in storage, moisture-proof packaging, and air drying systems. It has strong hygroscopicity and a significant dehumidification effect.

4. Oilfield Drilling and Completion Fluids

It is used as a drilling fluid stabilizer, operating fluid, and completion fluid to maintain downhole pressure and prevent shale expansion.

5. Food and Pharmaceutical Industries

Food-grade calcium chloride is used in calcium supplements, food coagulants, and preservation treatments, and in pharmaceuticals to maintain electrolyte balance.

6. Papermaking, Dyes, and Chemical Industries

It is used as an additive, coagulant, dehydrating agent, and reaction medium.
