Product Description
Basic Properties and Composition
The spherical pellets of calcium chloride dihydrate (referred to as "dihydrate calcium chloride pellets") are industrial - grade calcium chloride products. The main component is calcium chloride dihydrate (CaCl2.2H2O), which forms a specific physical form through the crystallization hydrate and granulation process.
Physical Form Characteristics
Appearance and Structure: It presents as regular spherical pellets with a uniform particle size (usually 2 - 5mm). The surface is smooth and dense, white or off - white in color, and the texture is hard and not easily broken.
Advantages of Functionalized Form: The spherical structure endows it with excellent fluidity, facilitating mechanical feeding, warehousing and stacking, and long - distance transportation. It can reduce the dust - flying problem of traditional powdered products. Chemical Characteristics and Behavior
Chemical formula: CaCl2.2H2O, namely calcium chloride dihydrate, is a crystalline compound in which calcium chloride combines with two crystal water molecules.
Appearance characteristics: It is
white spherical or granular crystals ("photosphere" may refer to its spherical particle appearance), with a smooth surface, a compact crystal structure, a particle size usually of 2 - 5mm, strong hygroscopicity, and is prone to deliquescence when exposed to air.
Chemical properties: It is easily soluble in water, and its aqueous solution is neutral to slightly alkaline (pH is about 7 - 8), and a large amount of heat is released during dissolution.
The melting point is about 260ºC. When heated above 300ºC, it loses crystal water and forms anhydrous calcium chloride (CaCl2). Hygroscopicity and Storage Requirements: It has strong hygroscopicity. When exposed to air, it easily absorbs moisture and deliquesces. It needs to be stored in a dry environment (recommended humidity < 60%) to avoid caking caused by package damage.
Dissolution Characteristics: It is easily soluble in water. When dissolving, it releases significant heat (heat of solution is about 17.2 kJ/mol). The formed aqueous solution is weakly acidic (pH 6.5 - 7.5), slightly acidic due to the hydrolysis of calcium ions. Adaptation of Process and Application Scenarios.

Application
Industrial-grade calcium chloride dihydrate (with "dihydrate spherical pellets" being one of its forms) serves as a proven de-icing agent in winter road maintenance. Its efficacy stems from its ability to depress the freezing point of water, enabling snow and ice to melt at subzero temperatures when applied to snow-covered roads, bridges, airport runways, and other infrastructure.Mechanism of ActionFreezing Point Depression
Upon dissolution in meltwater, calcium chloride dihydrate (CaCl2·2H2O) dissociates into Ca²+ and Cl ions, leveraging colligative properties to lower the freezing point.
For instance:A 20% calcium chloride solution exhibits a freezing point of -25°C, far below water's 0°C freezing point, allowing it to remain liquid in subfreezing conditions.Hygroscopic and Exothermic EffectsIts strong hygroscopicity draws moisture from snow/ice, initiating the melting process;The dissolution releases approximately 17.2 kJ/mol of heat, accelerating ice liquefaction through an exothermic reaction
Packaging & Shipping
Calcium Chloride is packaged in 25kg/1000kg PP Woven sacks with plastic liners, or as per customer's request.
Store in a cool, dry, well ventilated place. Keep container tightly closed and away from incompatible materials. Prolonged storage may cause product to cake and become wet from atmospheric moisture.
