What are 74% Calcium Chloride Granules?

Our 74% calcium chloride granules are a standardized chemical raw material specifically designed for industrial applications. It is made from high-quality natural brine through multiple refining processes. Its chemical name is calcium chloride, CAS number 10043-52-4, EC number 233-140-8, molecular formula CaCl₂, and molecular weight 110.98 g/mol.

This product maintains a stable calcium chloride content of 74%, strictly complying with the HG/T2327-2004 industrial grade calcium chloride standard. Sodium chloride impurity content is ≤2.5%, and water-insoluble matter content is ≤0.1%. All indicators have been verified by professional testing institutions. This product is a white to off-white solid granule with uniform particle size, good flowability, and easy storage, transportation, and feeding. It is a basic chemical raw material with extremely high cost-effectiveness in industrial production.

What are the product characteristics?

Our 74% calcium chloride granules possess a variety of excellent properties, perfectly meeting the needs of various industrial applications.

It possesses extremely strong hygroscopic properties. It can quickly absorb water vapor from the surrounding environment, effectively controlling ambient humidity. It also has excellent solubility, readily dissolving in water. After dissolving, it forms a clear, colorless solution. Furthermore, the dissolution process is accompanied by a significant exothermic reaction, rapidly increasing the solution temperature.

Additionally, this product exhibits significant deliquescence. In high-humidity environments, it can absorb large amounts of moisture until it forms a liquid solution. This characteristic makes it stand out in drying applications. Its freezing point is as low as -15℃, effectively lowering the freezing point of water and maintaining good performance even in low-temperature environments.

This product is odorless, non-toxic, and environmentally friendly, with a melting point as high as 782℃. It possesses extremely strong high-temperature stability, maintaining stable chemical properties under various industrial conditions, ensuring safe and reliable use.

What is the production process?

As a professional calcium chloride manufacturer, we employ a closed-loop production process to ensure the consistent quality of each batch of 74% granular calcium chloride.

In the raw material stage, we carefully select high-purity brine and perform multi-stage filtration to remove impurities, ensuring the purity of the raw materials. In the reaction stage, the Solvay process is employed. Hydrochloric acid and limestone are mixed in a precise ratio and neutralized in a reactor to generate a calcium chloride solution. Subsequently, excess water is removed from the solution through high-temperature evaporation and concentration, yielding a high-concentration calcium chloride stock solution.

The concentrated solution is cooled and crystallized to form solid calcium chloride, which is then processed into uniform granules using precision granulation technology. Finally, drying, sieving, and impurity removal processes ensure uniform particle size and meet purity standards.

The entire production process strictly adheres to the ISO9001-2008 quality management system. Each process is monitored in real-time by professional quality inspectors. Before leaving the factory, the finished product undergoes more than 20 tests to ensure a 100% pass rate.

What are the applications of this product?

74% calcium chloride granules have excellent performance and are widely used in multiple industrial fields.

In the road maintenance field, it is a highly efficient de-icing and snow-melting agent. When applied to roads and airport runways in winter, it quickly melts snow and ice, reducing the risk of icing and ensuring smooth traffic flow. Its corrosiveness to road surfaces is far lower than that of traditional rock salt.

In the construction industry, it can be used as a concrete accelerator. Added to concrete mixes, it accelerates hydration reactions and shortens setting time by more than 30%. It is particularly suitable for construction in low-temperature environments, helping projects to be completed on time.

In the oil and gas industry, this product is used as a drilling fluid additive, effectively controlling wellbore stability, preventing clay expansion, and ensuring drilling safety. Furthermore, it is widely used in industrial drying, water treatment, and dust removal, making it an indispensable multi-functional chemical raw material in industrial production.
