Flake calcium chloride is a common solid form of calcium chloride, presenting as white or grayish-white flakes. It has strong hygroscopicity and is prone to deliquescence (requiring sealed storage). Its chemical formula is CaCl₂, and it is highly soluble in water with a slight heat release during dissolution. It has a wide range of uses. In industry, it can be used as a desiccant, road de-icing agent and early strength agent for concrete. Food-grade products can be used as coagulants for soy products and preservatives for fruits and vegetables. It can also be used in the medical field to prepare physiological saline, among other applications. When in use, be cautious of its irritability. It is recommended to wear protective equipment.

APPLICATION

1. Desiccant/hygroscopic agent: Calcium chloride flakes are used to dry gases (such as nitrogen, oxygen, hydrogen), petroleum products (such as lubricating oil, fuel oil), and organic solvents (such as ethanol, acetone). By taking advantage of its extremely strong hygroscopic property, it absorbs moisture and prevents materials from getting damp and deteriorating.
2. Road and site snow and ice removal: As a de-icing agent, CaCl2 is spread on roads, parking lots, airport runways, etc. By lowering the freezing point of ice and snow (as low as -50 ℃), it accelerates the melting of ice and snow, and at the same time reduces the re-freezing of ice and snow, ensuring traffic safety.
3. Concrete additives: As early strength agents for concrete, they are added to concrete to promote the hydration reaction of cement, shorten the setting and hardening time of concrete, enhance early strength, and accelerate the construction progress of building projects (especially suitable for low-temperature construction environments).
4. Industrial wastewater treatment: CaCl2  is used to remove phosphates and heavy metal ions (such as lead, mercury, and cadmium) from industrial wastewater. Through chemical reactions, insoluble precipitates are formed to achieve pollutant separation. At the same time, it can adjust the pH value of the wastewater and neutralize acidic wastewater.
5. Refrigerant/cooling medium: Calcium chloride flakes is formulated into water solutions of different concentrations and used as the heat transfer medium in industrial cooling systems (such as chemical equipment and refrigeration units), taking advantage of its low freezing point to maintain the low-temperature cooling effect.
