What are the storage conditions for Calcium Chloride Granular?
Calcium Chloride Granular should be stored in a dry, cool and ventilated place. This is because of its strong hygroscopicity, if it is in a humid environment, it is easy to deliquescent and cause quality damage.
Where stored, the temperature should be controlled within a reasonable range and should not be too high. Under high temperatures, or cause changes in the chemical properties of calcium chloride, affecting its efficacy. For example, in some industrial applications, high temperatures may cause calcium chloride to participate in the reaction at a different rate than expected, which is unfavorable for product manufacturing.
Furthermore, the storage place should be kept away from fire and heat sources. Although calcium chloride is not flammable, there are fire sources, heat sources, or other dangerous conditions. If there are flammable substances around, it is easy to cause fire, and the temperature is abnormally elevated or affects the stability of calcium chloride.
also needs to be stored in isolation from acids, bases and active metal powders. Calcium chloride will chemically react with acids and bases, causing its own deterioration, and at the same time forming harmful and dangerous products. Coexistence with active metal powders may also trigger chemical reactions and threaten storage safety.
When storing, use a well-sealed container. This can not only prevent moisture absorption and deliquescence, but also avoid reaction with external substances. After taking it, be sure to seal the container in time to ensure its quality is stable. In short, following these storage conditions can ensure that the Calcium Chloride Granular maintains good quality and performance during storage.

These small packages are easy to access and accurate measurement, which is conducive to the development of experiments and the needs of fine production.
Second, the size of the medium package is often 5 kilograms, 10 kilograms, 25 kilograms. 5kg and 10kg packaging are quite common in small chemical processing and agricultural special application scenarios. The 25kg package is a more general specification and is widely used in various industrial applications, such as the production of road snow melting agents and the preparation of building antifreeze agents. Because of its moderate quality, it is easy to handle and store, and it is very convenient for industrial circulation.
Third, large packaging specifications are packed in ton bags, usually 1 ton. This specification is mainly used in large-scale industrial production enterprises, such as large-scale chemical enterprises for raw material procurement, large-scale road maintenance engineering materials, etc. Ton bag packaging can improve loading and unloading efficiency, reduce unit packaging costs, and is suitable for large-scale demand scenarios.
In addition, there are also special customized packaging specifications to meet the special needs of different customers. Or according to the customer's use frequency, storage conditions and other factors, customize the suitable packaging to achieve the best use and management effect.
Calcium Chloride Granular has a variety of packaging specifications, from small laboratory needs to large-scale industrial applications, to meet the requirements of different fields and scales of use.
What is the compatibility of Calcium Chloride Granular Compatibility Issues with Other Chemicals?
Calcium Chloride Granular is often used in chemical industry. It is active and combines with many other substances, and there is a question of whether it is compatible or not.
Looking at its relationship with acids, strong acids such as sulfuric acid and hydrochloric acid, calcium chloride is co-located with it. At room temperature, it has little chemical reaction and is multi-compatible. Covered calcium chloride is saline, and when it encounters strong acids, there is no precipitation between ions, gas or weak electrolytes, and the system is usually stable. However, when encountering weak acids, such as carbonic acid, although carbonic acid is easy to decompose, theoretically, if it is in a closed and carbon dioxide gas environment, or when calcium bicarbonate is generated, there is a slight change and the compatibility is slightly different.
As for bases, common bases such as sodium hydroxide and potassium hydroxide coexist with calcium chloride. In the ionic state, the concentration of calcium and hydroxide ions does not reach the solubility product, and there is no precipitation. However, in case of special organic bases, complex structures, or groups that can be complexed with calcium ions, it may be induced and incompatible.
Among salts, when it encounters silver nitrate salts, chlorine and silver ions rapidly form silver chloride precipitation, which is an obvious example of incompatibility. And with sodium salts, potassium salts and other common ones, if there is no special condition, there is no significant reaction between ions, and they are pluripotent compatible.
In organic compounds, non-polar organic compounds such as benzene and hexane have little effect and are compatible with calcium chloride. However, for polarity, such as alcohols, the hydroxyl groups in alcohols may have weak interactions with calcium ions, which may affect their compatibility at high concentrations or under special conditions.
In general, the compatibility of Calcium Chloride Granular with other substances depends on the nature of the encountered substance and environmental conditions (temperature, pressure, concentration, etc.). It is necessary to study the principle and material characteristics in detail to understand its compatibility.
What is the proportion of Calcium Chloride Granular used in different industries?
Calcium Chloride Granular, is wonderfully used in various industries, and its use cases are numerous, as follows:
In the road maintenance industry, every winter, ice and snow are blocked, in order to ensure the smooth passage of the road, Calcium Chloride Granular is often sprinkled on the road. The dosage varies according to the snow and icing conditions on the road. Most of the city streets, the dosage is about 50-100 grams per square meter; while on highways, due to the large traffic flow and high driving speed, in order to efficiently melt snow and prevent skid, 100-200 grams per square meter may be required.
This is because of its hygroscopicity, it can reduce the freezing point in case of ice and snow, promote the rapid melting of ice and snow, and have good anti-skid effect, which can protect the safety of vehicles and pedestrians.
In the field of construction, it is also indispensable. When mixing concrete, an appropriate amount of Calcium Chloride Granular is added, which can be used as an early strength agent. It can speed up the concrete setting and hardening process and improve early strength. Generally speaking, the amount of calcium chloride added to each cubic meter of concrete is about 1% - 2% of the cement quality.
In this way, construction in cold weather can prevent concrete from freezing damage and ensure the progress and quality of the project.
In the food industry, Calcium Chloride Granular is also useful. Often used as a food additive, such as in the processing of soy products, it can solidify soy milk into tofu, optimize the texture of tofu, and increase its toughness and water retention. For fruit and vegetable preservation, treating with a certain concentration of calcium chloride solution can prolong the preservation period. If apples are kept fresh, they can be soaked in a solution with a mass fraction of 2% - 4% calcium chloride to protect their color and taste.
In the oil drilling industry, Calcium Chloride Granular also plays a big role. Adding it to the drilling fluid can regulate its properties, such as enhancing the density and viscosity of the drilling fluid, stabilizing the well wall, and preventing collapse and blowout. The dosage depends on the drilling formation condition and the drilling fluid formula, usually accounting for 0.5% - 3% of the drilling fluid quality.
In the field of chemical production, Calcium Chloride Granular is widely used. In the manufacture of desiccants, it is often the first choice for raw materials because of its strong moisture absorption. In the gas drying process, it can efficiently remove water vapor in the gas. For example, drying nitrogen, oxygen and other gases can greatly reduce the water content of the gas and reach industrial production standards after drying with calcium chloride.
In summary, Calcium Chloride Granular is widely used in various industries, and the dosage varies according to specific scenarios and needs, but it is a key factor in promoting the production and operation of various industries.
