1. Oil and gas industry Drilling fluid additives: As a flocculant and inhibitor of drilling fluid, it can adjust the viscosity of drilling fluid, prevent clay expansion, and improve drilling efficiency; it is used as a density regulator in completion fluid to avoid the risk of blowout. Natural gas dehydration: It uses high hygroscopicity to absorb moisture in natural gas and prevent pipelines from being blocked due to the formation of hydrates. It is a key desiccant for natural gas purification. 2. Road and engineering fields Snow melting and deicing: Spherical particles have good fluidity and can be evenly sprayed on roads and airport runways by spreaders. They absorb moisture and release heat to accelerate the melting of ice and snow, and reduce dust pollution compared to powder. Concrete additives: As an early strength agent, it is added to concrete to shorten the solidification time and improve the construction strength in low temperature environments. It is often used for winter engineering repairs. 3. Chemical and pharmaceutical industries Desiccant and dehydrating agent: In chemical production, it is used to dry industrial gases such as nitrogen and oxygen, or as a dehydrating agent for organic solvents (such as ethanol and ether) to ensure that the reaction system is free of water. Pharmaceutical intermediates: used to prepare antiarrhythmic drugs, electrolyte supplements, etc., and its spherical particles are convenient for precise measurement and preparation processing. 4. Food and agricultural applications Food processing: added to canned food and soy products as a calcium fortifier, and at the same time using hygroscopicity to keep food dry (such as fried food to prevent moisture), in line with the "Food Additives Use Standard" (GB 1886.45-2016). Agricultural preservation: Spraying fruits and vegetables with calcium chloride solution to delay the decomposition of cell walls during ripening and extend the shelf life. It is often used in cold chain transportation of apples and grapes. 5. Environmental protection and water treatment Wastewater treatment: Remove pollutants such as phosphates and fluorides from wastewater through coagulation to form precipitates for easy filtration, especially suitable for deep treatment of industrial fluoride-containing wastewater. Dust control: Spray spherical calcium chloride solution in mines and construction sites, use hygroscopicity to adhere to dust particles, reduce dust concentration in the air, and improve the working environment. 6. Energy storage and materials Phase change energy storage materials: compounded with other salts to form a phase change thermal storage system, used for solar thermal storage and building heating systems, using the dissolution-crystallization process to achieve heat storage and release. Molecular sieve raw materials: spherical particles can be further processed to make molecular sieves with excellent adsorption properties, which are used for gas separation (such as purification of oxygen and nitrogen).

Compared with ordinary calcium chloride (such as powder and flake), Calcium Chloride Spherical has multiple advantages in form, performance and application scenarios. Its core advantage comes from the standardized structure of spherical particles: first, it has excellent fluidity and is not easy to clog the pipeline when it is placed by a spreader or automated equipment. The metering accuracy is 40% higher than that of powder, which is especially suitable for scenes that require uniform dispersion such as road snow melting and drilling fluid addition. Secondly, spherical particles have a high packing density (about 1.2-1.4g/cm³) and a uniform specific surface area. In chemical reactions, they can avoid local overheating caused by powder agglomeration, and the fluctuation range of the reaction rate is reduced by 30%. They are often used in chemical drying, concrete early strength agent and other fields that require high reaction stability. In addition, storage and transportation are more convenient-the friction coefficient between particles is low, the packaging breakage rate is 60% lower than that of flakes, and the probability of moisture absorption and agglomeration is significantly reduced, and there is no need to frequently turn the stacks during storage. In terms of environmental protection, the amount of dust raised by spherical particles is 50% less than that of powder, which meets the dust control standards for scenes such as mines and construction sites. Although the production cost is 15%-20% higher than that of ordinary forms, Calcium Chloride Spherical achieves cost optimization due to its operational efficiency and performance stability in scenarios that require automated delivery, precise metering or high safety. It is especially suitable for industries such as oil drilling and food processing that have strict requirements on material form.

The production process of Calcium Chloride Spherical is centered on "liquid purification-precision granulation-gradient drying", and the standardized preparation of spherical particles is achieved through multi-stage process control. First, industrial-grade calcium chloride solution (concentration of about 30%-40%) or natural brine is used as raw material, and impurities such as magnesium and iron are removed by soda precipitation method, and then finely filtered through a plate and frame filter press to obtain a clear solution with a purity of ≥94%. Then enter the key granulation link: using a pressure spray granulation process, the purified solution is transported to the atomizing nozzle through a high-pressure pump (pressure 8-12MPa), and in the drying tower, it is reversely contacted with 300-350℃ hot air. The solution is instantly atomized into micron-sized droplets, which naturally shrink into a sphere due to surface tension, and the initial drying is completed at the same time (the moisture content is reduced to 10%-15%). Next, the particles enter the fluidized bed dryer and are gradient dried by hot air at 70-90°C to reduce the moisture content to below 2%. During this period, spherical particles with a particle size of 0.5-2mm are screened out by a vibrating screening device (screening efficiency ≥95%). For food-grade products, ultraviolet sterilization is also required in a sterile environment, and the particle uniformity is further optimized by an air flow classifier (particle size deviation ≤±0.2mm). The entire process is monitored in real time by the DCS system for temperature, pressure and particle size distribution to ensure that the bulk density (1.2-1.4g/cm³) and fluidity (angle of repose ≤35°) of the spherical particles meet industrial application standards. Compared with the traditional flake process, the energy consumption of the granulation process increases by about 20%, but the added value of the product increases by more than 30%. Therefore, when storing and using powdered calcium chloride, be sure to be careful to avoid these "reaction partners". Otherwise, at best the original properties of calcium chloride will be lost, and at worst it may cause danger!

The storage and transportation of Calcium Chloride Spherical should be combined with its spherical particle characteristics and chemical properties, and follow the following specifications to ensure stable product performance: Storage points: It should be stored in a dry and ventilated warehouse, and a moisture-proof pad (≥15cm from the ground) should be laid on the ground to avoid direct contact with the wet ground. Because spherical particles have strong hygroscopicity, the humidity in the warehouse must be controlled below 60%, the temperature should not exceed 30℃, and it should be kept away from heat sources and acidic gases (such as sulfur dioxide) to prevent deliquescence or chemical reactions. The packaging should be woven bags (industrial grade) lined with food-grade polyethylene film or fully sealed plastic barrels (food grade). The seal must be tight, and the bag mouth must be tied in time when it is not used up to avoid long-term contact between the particles and the air and moisture absorption and agglomeration. Different purity levels (such as 74%, 94%) need to be stored in separate areas, and obvious signs should be set to prevent mixed loading and misuse. Transportation requirements: Waterproof tarpaulins must be used to cover during transportation to avoid rain and exposure to the sun. Clean and dry carriages should be used for rail or road transportation. Mixing with toxic and hazardous goods (such as pesticides and chemical waste) is prohibited. Spherical particles have good fluidity, so the stacking height must be controlled during loading (≤2.5 meters), and barrier measures must be used to prevent sliding and reduce the rate of package damage. For food-grade products, special food transportation tools must be used. Handle with care during loading and unloading to avoid dust caused by rupture of the packaging bag. The transportation temperature should be kept between -5℃ and 40℃ to prevent freezing at low temperatures or accelerated decomposition at high temperatures, and ensure that the particle integrity is ≥98% and the moisture content is maintained below 2% when arriving at the destination.

The market price of Calcium Chloride Spherical is affected by purity grade, particle size specifications, production scale and application field, and presents a certain fluctuation range. At present, the mainstream quotation of industrial-grade 74% purity spherical calcium chloride (particle size 0.5-2mm) is 1200-1500 yuan/ton. The price of 94% high-purity products is increased to 1800-2200 yuan/ton due to the complex purification process. Food grade (in accordance with GB 1886.45 standard) requires aseptic treatment and precision screening, and the price range is 2500-3200 yuan/ton. Specifically, the price of Calcium Chloride Spherical for oil drilling (requires fluidity ≥35°/s) is 15%-20% higher than that of ordinary industrial grade due to the addition of anti-caking additives; ultra-pure products used for pharmaceutical intermediates (purity ≥96%, impurity ions ≤10ppm) can reach 4000-5000 yuan/ton. In terms of regional differences, the prices in East China and South China are 300-500 yuan/ton lower than those in North China and Northwest China due to lower transportation costs; in the peak season for snowmelt demand in winter (November-February), the price of industrial-grade products will rise by 10%-15% in the short term, while in summer, due to weak demand, it may drop by about 5%. When purchasing on a large scale, a single order of ≥50 tons can enjoy a 10%-15% discount, and the price for long-term strategic cooperation customers can be reduced to 1000-1300 yuan/ton for industrial grade. It should be noted that since 2023, affected by the rising prices of calcium chloride raw materials (hydrochloric acid, limestone), the overall price has risen by about 200-300 yuan/ton compared with the same period in 2022. It is expected that in the next six months, the price will fluctuate in a narrow range with the fluctuations in the chemical raw materials market.
