Product introduction of anhydrous spherical calcium chloride

Anhydrous spherical calcium chloride is a common inorganic salt compound with the chemical formula of CaCl₂. Because it is anhydrous, easily soluble in water, and has strong hygroscopicity, it has a wide range of applications in industry and life. Anhydrous spherical calcium chloride usually appears in the form of particles or spheres, named after the “spherical” form, and its shape is similar to a small ball, which helps to improve its dissolution rate and hygroscopicity.

1. Physical and chemical properties of anhydrous spherical calcium chloride

Molecular formula and molecular weight
The molecular formula of anhydrous calcium chloride is CaCl₂, and the molecular weight is 110.98 g/mol.
Appearance and morphology
It usually appears as white spherical particles with uniform particles and good fluidity. The shape of the spherical particles has a large specific surface area, which increases the contact area with the air and improves the moisture absorption efficiency.
Density
The density of anhydrous spherical calcium chloride is about 2.15 g/cm³.
Melting point and boiling point
The melting point is about 772℃, the boiling point is 1600℃, and it has good stability at high temperature.
Solubility and hygroscopicity
It is easily soluble in water, releases heat in water, and can quickly absorb moisture in the air to form hydrated calcium chloride. The spherical structure greatly improves the hygroscopic effect.

2. Preparation method of anhydrous spherical calcium chloride

Calcium chloride solution evaporation method
Calcium hydroxide or calcium carbonate is reacted with hydrochloric acid to generate calcium chloride solution, which is filtered to remove impurities, and then the calcium chloride solution is evaporated, concentrated and dried to obtain anhydrous calcium chloride.
Direct heating method of calcium carbonate
Calcium carbonate is heated to react with chlorine to generate calcium chloride gas, and then anhydrous calcium chloride is obtained by capture and condensation, and then processed into spherical particles.
Spiky ball forming process
The prepared calcium chloride is molded and the flow rate is controlled during the granulation stage to form a uniform spiky ball shape, which increases its contact area and ensures more efficient moisture absorption during use.

3. Main uses of anhydrous spiky ball calcium chloride

Industrial desiccant
Spiky ball calcium chloride has strong moisture absorption capacity and is suitable for industrial desiccant. In the fields of air conditioning, refrigeration, gas drying, etc., it can remove moisture from air and gas to achieve moisture-proof effect.
De-icing agent
On roads in cold areas, anhydrous calcium chloride, as an effective de-icing agent, can quickly reduce the melting point of ice and snow, help melt ice and snow on the road, and ensure driving safety. The spiky ball particles increase the contact area, allowing them to contact and react with ice and snow faster.
Cement and construction industry
In cement production, anhydrous calcium chloride is used as an accelerator to help accelerate the solidification of cement, especially at low temperatures, and improve construction efficiency. In addition, its addition to concrete can increase early strength and improve the compressive properties of building materials.
Food Industry
In food processing, calcium chloride is often used as a coagulant, anti-caking agent and preservative to ensure the stability and safety of food texture. It is especially widely used in canned and dairy processing.
Water Treatment Industry
Calcium chloride can be used to remove impurities and harmful ions in water during sewage treatment, and settle suspended matter through precipitation reaction to achieve the purpose of purifying water quality.
Agriculture and Animal Husbandry
In agriculture, calcium chloride is used to improve soil structure, supplement calcium elements, and prevent diseases caused by calcium deficiency during crop growth. It is also used as a feed additive in animal husbandry to help livestock supplement calcium.
Medicine and Laboratory Reagents
Anhydrous spiky ball calcium chloride is used in pharmaceutical production to prepare calcium supplements, detoxifiers and other medicines. In laboratories, it is a commonly used desiccant for various chemical reactions or gas drying.

4. Use and storage of anhydrous thorn ball calcium chloride

Usage method
When using thorn ball calcium chloride, it should be placed in an area with good air circulation as much as possible to improve its moisture absorption speed and efficiency. It is usually placed in a closed environment as a desiccant to ensure the effect.
Storage method
Calcium chloride should be stored in a dry, cool, well-ventilated environment, avoiding exposure to moisture and air to prevent moisture absorption and self-dissolution. Since anhydrous calcium chloride is irritating to the skin, gloves and goggles should be worn during operation.
Packaging and transportation
Calcium chloride is generally packaged in plastic barrels or plastic bags and sealed to prevent deterioration due to absorption of moisture in the air during transportation.

5. Safety of anhydrous thorn ball calcium chloride

Hygroscopic properties
Calcium chloride has strong hygroscopicity. Direct contact with the skin may cause dryness and irritation. Contact with the eyes may cause strong discomfort. If necessary, rinse and seek medical attention.
Health effects
Although calcium chloride is non-toxic in most cases, direct contact or inhalation of excessive dust can irritate the respiratory tract. It is recommended to wear protective equipment during operation.
Environmental protection
Calcium chloride itself is not a hazardous chemical, but it may cause salt pollution after large-scale use. Therefore, it needs to be properly handled after use to avoid environmental pollution.

VI. Market application prospects of anhydrous spiky ball calcium chloride

As a high-efficiency desiccant and industrial raw material, the market demand for anhydrous spiky ball calcium chloride has increased year by year. With the rapid development of modern industry, the demand for calcium chloride in fields such as drying, dehumidification, snow melting and water treatment has increased significantly. At the same time, the manufacturing technology of spiky ball anhydrous calcium chloride has gradually matured, creating conditions for its promotion and application in a wider range of fields.

In addition, under the increasingly stringent environmental protection requirements, spiky ball calcium chloride is widely used in environmental protection technologies such as sewage treatment and air drying, showing good application value.
